MYC is a transcription factor that depends on several binding partners to function. We therefore explored the possibility of targeting MYC via its interactome in pancreatic ductal adenocarcinoma (PDAC). Design To identify the most suitable targets among all MYC binding partners, we constructed a targeted shRNA library and performed screens in cultured PDAC cells and tumours in mice. Results Unexpectedly, many MYC binding partners were found to be important for cultured PDAC cells but dispensable in vivo. However, some were also essential for tumours in their natural environment and, among these, the ATPases RUVBL1 and RUVBL2 ranked first. Degradation of RUVBL1 by the auxin-degron system led to the arrest of cultured PDAC cells but not untransformed cells and to complete tumour regression in mice, which was preceded by immune cell infiltration. Mechanistically, RUVBL1 was required for MYC to establish oncogenic and immunoevasive gene expression identifying the RUVBL1/2 complex as a druggable vulnerability in MYC-driven cancer. Conclusion One implication of our study is that PDAC cell dependencies are strongly influenced by the environment, so genetic screens should be performed in vitro and in vivo. Moreover, the auxin-degron system can be applied in a PDAC model, allowing target validation in living mice. Finally, by revealing the nuclear functions of the RUVBL1/2 complex, our study presents a pharmaceutical strategy to render pancreatic cancers potentially susceptible to immunotherapy. Data are available in a public, open access repository. Primary sequencing data (shRNA screen, SLAM-seq, ChIP-seq, RNA-seq) have been deposited in the Gene Expression Omnibus under the accession number GSE216095.

MYC is a transcription factor that depends on several binding partners to function. We therefore explored the possibility of targeting MYC via its interactome in pancreatic ductal adenocarcinoma (PDAC). Design To identify the most suitable targets among all MYC binding partners, we constructed a targeted shRNA library and performed screens in cultured PDAC cells and tumours in mice. Results Unexpectedly, many MYC binding partners were found to be important for cultured PDAC cells but dispensable in vivo. However, some were also essential for tumours in their natural environment and, among these, the ATPases RUVBL1 and RUVBL2 ranked first. Degradation of RUVBL1 by the auxin-degron system led to the arrest of cultured PDAC cells but not untransformed cells and to complete tumour regression in mice, which was preceded by immune cell infiltration. Mechanistically, RUVBL1 was required for MYC to establish oncogenic and immunoevasive gene expression identifying the RUVBL1/2 complex as a druggable vulnerability in MYC-driven cancer. Conclusion One implication of our study is that PDAC cell dependencies are strongly influenced by the environment, so genetic screens should be performed in vitro and in vivo. Moreover, the auxin-degron system can be applied in a PDAC model, allowing target validation in living mice. Finally, by revealing the nuclear functions of the RUVBL1/2 complex, our study presents a pharmaceutical strategy to render pancreatic cancers potentially susceptible to immunotherapy. Data are available in a public, open access repository.

id="abstract-1"><h2>Abstract</h2><div id="sec-1" class="subsection"><p id="p-3"><strong>Objective</strong> The hallmark oncogene MYC drives the progression of most tumours, but direct inhibition of MYC by a small-molecule drug has not reached clinical testing. MYC is a transcription factor that depends on several binding partners to function. We therefore explored the possibility of targeting MYC via its interactome in pancreatic ductal adenocarcinoma (PDAC).</p></div><div id="sec-2" class="subsection"><p id="p-4"><strong>Design</strong> To identify the most suitable targets among all MYC binding partners, we constructed a targeted shRNA library and performed screens in cultured PDAC cells and tumours in mice.</p></div><div id="sec-3" class="subsection"><p id="p-5"><strong>Results</strong> Unexpectedly, many MYC binding partners were found to be important for cultured PDAC cells but dispensable in vivo. However, some were also essential for tumours in their natural environment and, among these, the ATPases RUVBL1 and RUVBL2 ranked first. Degradation of RUVBL1 by the auxin-degron system led to the arrest of cultured PDAC cells but not untransformed cells and to complete tumour regression in mice, which was preceded by immune cell infiltration. Mechanistically, RUVBL1 was required for MYC to establish oncogenic and immunoevasive gene expression identifying the RUVBL1/2 complex as a druggable vulnerability in MYC-driven cancer.</p></div><div id="sec-4" class="subsection"><p id="p-6"><strong>Conclusion</strong> One implication of our study is that PDAC cell dependencies are strongly influenced by the environment, so genetic screens should be performed in vitro and in vivo. Moreover, the auxin-degron system can be applied in a PDAC model, allowing target validation in living mice. Finally, by revealing the nuclear functions of the RUVBL1/2 complex, our study presents a pharmaceutical strategy to render pancreatic cancers potentially susceptible to immunotherapy.</p></div></div><ul class="kwd-group"><li class="kwd">PANCREATIC CANCER</li><li class="kwd">GENE REGULATION</li><li class="kwd">ONCOGENES</li><li class="kwd">IMMUNOTHERAPY</li><li class="kwd">GENE TARGETING</li></ul><div class="section data-availability" id="sec-40"><h2 class="">Data availability statement</h2><p id="p-122">Data are available in a public, open access repository.

Patients with PDAC have a median survival of less than 1 year,<a id="xref-ref-2-1" class="xref-bibr" href="#ref-2">2</a> resulting in 530 000 deaths per year worldwide.</p><p id="p-11">The main limitation of targeted cancer therapy, in general and particularly in PDAC, is its narrow applicability. Indeed, each targeted therapy is designed for a specific subset of patients whose tumours have specific genetic profiles.<a id="xref-ref-3-1" class="xref-bibr" href="#ref-3">3</a> While the availability of a targeted therapy is an attractive therapeutic option for this particular patient subgroup, the corresponding genetic mutation is often rare, so the number of patients who can benefit is small. This conundrum also applies to immunotherapies, where only patients with an immunologically active tumour microenvironment benefit from immune checkpoint blockade.<a id="xref-ref-4-1" class="xref-bibr" href="#ref-4">4</a> To date, it has proven impossible to develop a universally applicable targeted cancer therapy by inhibiting common oncogenes.</p><p id="p-12">An important example of oncogenes with universal significance is the family of MYC transcription factors, which comprises c-MYC (called MYC hereafter), NMYC and LMYC.<a id="xref-ref-5-1" class="xref-bibr" href="#ref-5">5 6</a> Several lines of experimental and clinical research suggest that MYC should be an outstanding cancer target. Most tumours have deregulated MYC expression caused by various mechanisms including somatic gene amplifications and translocations, mutations that increase MYC protein stability and alterations in upstream pathways that enhance MYC transcription.<a id="xref-ref-7-1" class="xref-bibr" href="#ref-7">7</a> The link between high MYC expression and tumorigenesis is causative, since exogenous expression of MYC in mouse models initiates<a id="xref-ref-8-1" class="xref-bibr" href="#ref-8">8</a> or accelerates<a id="xref-ref-9-1" class="xref-bibr" href="#ref-9">9</a> tumour development. Importantly, deregulated MYC expression drives tumour initiation and renders established tumours ‘addicted’ to it, since silencing exogenous MYC irreversibly eradicates tumour cells.<a id="xref-ref-10-1" class="xref-bibr" href="#ref-10">10–14</a> Moreover, systemic expression of a dominant negative allele of MYC, called Omomyc, induced regression of established murine tumours but was tolerated by normal cells,<a id="xref-ref-15-1" class="xref-bibr" href="#ref-15">15</a> suggesting the existence of a therapeutic window for the pharmaceutical inactivation of MYC. Strikingly, periodic inhibition of endogenous MYC by Omomyc permanently prevented tumour progression in mice without any sign of resistance.<a id="xref-ref-16-1" class="xref-bibr" href="#ref-16">16</a> Recombinant Omomyc showed therapeutic efficacy in preclinical models of lung cancer<a id="xref-ref-17-1" class="xref-bibr" href="#ref-17">17</a> and has been tested for safety in a phase I clinical trial (<a class="external-ref external-ref-type-clintrialgov" href="/lookup/external-ref?link_type=CLINTRIALGOV&access_num=NCT04808362&atom=%2Fgutjnl%2F73%2F9%2F1509.atom">NCT04808362</a>).<a id="xref-ref-18-1" class="xref-bibr" href="#ref-18">18</a> </p><p id="p-13">Clinical testing of an MYC-derived therapeutic protein is exciting, but it might be difficult to deliver macromolecules to tumours in organs such as the brain and pancreas.<a id="xref-ref-19-1" class="xref-bibr" href="#ref-19">19</a> Indeed, protein-based drugs have more limited drug-delivery properties compared with small-molecule drugs, but so far no small-molecule inhibitor of MYC has advanced to clinical testing for various reasons. MYC lacks catalytic activity that can be easily inhibited; instead, MYC functions by binding other proteins and DNA. The DNA-binding domain of MYC is formed by extensive interactions with its partner MAX<a id="xref-ref-20-1" class="xref-bibr" href="#ref-20">20</a> and is structurally similar to the corresponding domains of other basic helix-loop-helix transcription factors. The transactivation domain of MYC is intrinsically disordered. These structural features impede the development of small-molecule drugs that directly inhibit MYC.</p><p id="p-14">An attractive alternative to inhibiting MYC directly is targeting a binding partner that is a better drug target than MYC itself. MYC’s DNA binding and transactivation activities both depend on MYC binding partners, as has been explicitly shown for MAX, WDR5, PAF, SPT5 and TRRAP.<a id="xref-ref-21-1" class="xref-bibr" href="#ref-21">21–28</a> However, MYC has broad affinity to other proteins, and dozens of putative binding partners have been identified by systematic proteomics methods.<a id="xref-ref-28-1" class="xref-bibr" href="#ref-28">28–31</a> It is currently unclear which of them are essential for MYC function and oncogenic growth in PDAC. We therefore used a targeted shRNA library to analyse the dependence of pancreatic cancer cells on 91 MYC binding partners, in vitro and in vivo. Our genetic screens revealed that among the most essential MYC binding partners were RUVBL1 and RUVBL2, which are AAA ATPases that form heteromeric complexes. We observed that oncogenic MYC expression renders cells dependent on the activity of the RUVBL1/2 complex and that acute depletion or inhibition of RUVBL1 provokes immune infiltration and eradicates pancreatic tumours in mice.</p></div><div class="section results" id="sec-9"><h2 class="">Results</h2><div id="sec-10" class="subsection"><h3>Genetic dropout screens reveal differential dependence on MYC binding partners in PDAC in vitro and in vivo</h3><p id="p-15">To assess the essentiality of MYC binding partners in PDAC, we generated a doxycycline-inducible shRNA library (containing five shRNAs per gene and 18 non-targeting control (NTC) shRNAs)<a id="xref-ref-32-1" class="xref-bibr" href="#ref-32">32</a> against 91 MYC binding partners identified in quantitative mass spectrometry (MS) experiments of natively isolated MYC complexes.

After 14 days, genomic DNA was isolated and sequenced to identify integrated shRNAs in the two treatment groups. This analysis showed that for each shRNA the changes were similar among three replicates, and for each MYC binding partner the changes were similar among the five shRNAs, documenting the robustness of the screening system (<a id="xref-fig-1-2" class="xref-fig" href="#F1">figure 1B</a>).

We therefore engrafted 10 mice with 100 000 cells each, induced shRNA expression by doxycycline in five of the animals and analysed integrated shRNA abundance in tumours after 14 days.</p><p id="p-22">First, we compared the abundance of integrated shRNA in the five tumours of the untreated mice with that in the originally transduced KPC cells (<a id="xref-fig-1-4" class="xref-fig" href="#F1">figure 1C</a>). No shRNA was found to be significantly depleted in tumours, confirming that shRNA expression is not induced in the absence of doxycycline. In a comparison between doxycycline-treated and untreated mice, 70 of the 460 targeting shRNAs were significantly depleted (log2 fold change (log2FC) <−1, p<0.05), while the abundance of the 18 NTC shRNAs was unchanged (<a id="xref-fig-1-5" class="xref-fig" href="#F1">figure 1D</a>). When we examined the median shRNA change per gene, we observed that only 26 MYC binding partners were significantly depleted (<a id="xref-fig-1-6" class="xref-fig" href="#F1">figure 1E,F</a>).</p><p id="p-23">To understand how the dependency of KPC cells differs between the in vitro and in vivo conditions, we compared the doxycycline-induced change in all MYC binding partners in a scatter plot (<a id="xref-fig-1-7" class="xref-fig" href="#F1">figure 1G</a>; see also <a id="xref-supplementary-material-3-3" class="xref-supplementary-material" href="#DC3">online supplemental table 2</a>). This analysis revealed that 31 MYC binding partners, such as the SMARCD2 subunit of the SWI/SNF chromatin remodelling complex, are not essential in either condition. Furthermore, 34 MYC binding partners were found to be essential in vitro but dispensable in vivo.

This observation is also consistent with the dominant-negative function of Omomyc, which shifts MAX from activating MYC/MAX to transcriptionally inactive Omomyc/Max dimers.<a id="xref-ref-15-2" class="xref-bibr" href="#ref-15">15 16 42 43</a> </p><p id="p-24">Finally, 27 genes were found to be essential both in vitro and in vivo.

Therefore, we studied RUVBL1 and MYC binding to chromatin globally in KPC<em> <sup>AID-Ruvbl1; TIR1</sup> </em> cells treated with vehicle or auxin by chromatin immune precipitation (ChIP) followed by sequencing. In vehicle-treated cells, RUVBL1 occupied 10 016 genomic sites, of which 7386 were in RNAPII promoters (<a id="xref-supplementary-material-2-23" class="xref-supplementary-material" href="#DC2">online supplemental figure S4F</a>). Auxin-mediated depletion of RUVBL1 drastically reduced the number of RUVBL1-occupied sites to 805 and brought the signals at promoters to background levels (<a id="xref-fig-4-4" class="xref-fig" href="#F4">figure 4E,F</a>). MYC occupied 15 991 genomic sites, of which 7906 were in promoters (<a id="xref-supplementary-material-2-24" class="xref-supplementary-material" href="#DC2">online supplemental figure S4F</a>).

These analyses revealed that genes activated by RUVBL1 have higher promoter occupancy of both MYC and RUVBL1 than non-regulated and repressed genes.

However, at later time points the bioluminescence increased, and tumours returned to their starting sizes despite auxin treatment. Instead, tumours in all vehicle-treated animals grew progressively from the start of the experiment. Survival analysis showed that auxin-induced RUVBL1 depletion provided a strong survival advantage, with a median survival time of 47 vs 25 days in the vehicle-treated group (<a id="xref-fig-6-4" class="xref-fig" href="#F6">figure 6E</a>).

To first investigate whether the toxicity of CB-6644 in KPC cells is due to specific inhibition of RUVBL1, we stably expressed an inhibitor-resistant RUVBL1 mutant (RUVBL1<sup>A62T</sup>).<a id="xref-ref-49-2" class="xref-bibr" href="#ref-49">49</a> Both native KPC cells and KPC cells overexpressing wild-type RUVBL1 were sensitive to CB-6644 (IC<sub>50</sub>=50 nM).

To this end, we first quantified MYC and RUVBL1 levels in a panel of pancreatic cancer cells by immunoblotting (<a id="xref-fig-7-5" class="xref-fig" href="#F7">figure 7D</a>) and observed a strong correlation between the levels of both proteins (<a id="xref-fig-7-6" class="xref-fig" href="#F7">figure 7E</a>) and between their levels and sensitivity to CB-6644 as estimated in cell growth assays (<a id="xref-fig-7-7" class="xref-fig" href="#F7">figure 7F</a>).</p><p id="p-54">Subsequently, we silenced MYC in KPC cells with a doxycycline-inducible shRNA (<a id="xref-supplementary-material-2-44" class="xref-supplementary-material" href="#DC2">online supplemental figure S7C</a>) and treated them with 200 nM CB-6644. In cells not exposed to doxycycline, viability was strongly reduced (89±14%) by CB-6644 treatment.

This finding is remarkable, since the concentration of CB-6644 was higher in all tested healthy tissues than in pancreatic tumours (34 times higher in spleen, <a id="xref-supplementary-material-2-47" class="xref-supplementary-material" href="#DC2">online supplemental figure S7F</a>) and since the limited solubility of CB-6644 prevented the use of higher, possibly more effective doses. Strikingly, no CB-6644-treated mouse reached the endpoint during the 28-day treatment, while all vehicle-treated mice did (<a id="xref-fig-7-9" class="xref-fig" href="#F7">figure 7I</a>). Thus, the median survival time of tumour-bearing mice was doubled by CB-6644 treatment. We next wondered if CB-6644-mediated inhibition of RUVBL1 would also synergise with αPD-1 treatment, as it did with auxin-mediated depletion. We therefore transplanted naïve KPC cells into 32 mice and, based on tumour size on day 7, sorted the mice into groups with similar size tumours, each receiving CB-6644 or αPD-1 treatment, combinatorial treatment or vehicle injections. While both CB-6644 and αPD-1 mono treatments slowed tumour growth, the combinatorial treatment induced tumour regression (<a id="xref-fig-7-10" class="xref-fig" href="#F7">figure 7J</a>) and most profoundly extended the life span of tumour-bearing mice (<a id="xref-fig-7-11" class="xref-fig" href="#F7">figure 7K</a>). Finally, inhibition of RUVBL1 by CB-6644 for 5 days caused infiltration of CD3-positive immune cells in tumours induced by a second KPC cell line (9172) and murine PDAC cells driven by the mutations <em>Kras<sup>G12D/+</sup> </em> and <em>Cdkn2a<sup>−/</sup> </em> <sup>−</sup> (24031), indicating that RUVBL1-mediated immune evasion is not restricted to the initially used KPC cell line (<a id="xref-supplementary-material-2-48" class="xref-supplementary-material" href="#DC2">online supplemental figure S7G,H</a>). Overall, we concluded that high MYC expression renders pancreatic cancer cells dependent on RUVBL1/2 and that inhibition of the RUVBL1/2 complex is therapeutic at doses tolerated by healthy tissues.</p></div></div><div class="section discussion" id="sec-18"><h2 class="">Discussion</h2><p id="p-57">The hallmark oncogene MYC plays a crucial role in tumorigenesis and is considered a key therapeutic target based on many studies in murine tumour models.<a id="xref-ref-7-2" class="xref-bibr" href="#ref-7">7 10 16</a> Here, we explored the approach of targeting MYC via its interactome. MYC depends on its binding partners for function, but it was unclear which of these are most relevant for oncogenic growth and tumour maintenance.</p><p id="p-58">To narrow down the spectrum of MYC binding partners, we performed a series of genetic screens in cultured PDAC cells and fibroblasts, as well as in murine pancreatic tumours. Among the candidates essential for PDAC growth in vivo but dispensable for fibroblasts, the two complex-forming proteins RUVBL1 and RUVBL2 scored highest. RUVBL1 depletion mimicked cellular phenotypes previously observed on MYC depletion in pancreatic cancer cells. For instance, depletion of RUVBL1 (in this study) or MYC<a id="xref-ref-26-1" class="xref-bibr" href="#ref-26">26 35</a> resulted in S-phase arrest but not apoptosis in cultured cells. Furthermore, depletion of either protein in immunocompetent mice led to the rapid regression of pancreatic tumours accompanied by immune cell infiltration, as shown here for RUVBL1 and earlier for MYC.<a id="xref-ref-12-3" class="xref-bibr" href="#ref-12">12 35 51</a> </p><p id="p-59">Consistent with these phenotypic similarities is our observation that high MYC expression levels make cancer cells dependent on the full activity of RUVBL1. We therefore consider the MYC-RUVBL1 axis to be a targetable vulnerability in cancer cells, since the RUVBL1/2 complex is a druggable AAA ATPase.<a id="xref-ref-56-1" class="xref-bibr" href="#ref-56">56</a> In fact, the allosteric RUVBL1/2 inhibitor CB-6644 had previously been shown to arrest Ewing sarcoma and multiple myeloma in immunocompromised mice<a id="xref-ref-49-3" class="xref-bibr" href="#ref-49">49 54</a> and had a striking therapeutic effect on pancreatic tumours at tolerated concentrations in immunocompetent mice in our study. However, because of the drug’s low solubility and unfavourable pharmacokinetics, it was not possible to establish higher, possibly even more effective drug concentrations in pancreatic tumours. Nonetheless, we expect that it will be possible to develop inhibitors of RUVBL1 with a better pharmacokinetic profile.</p><p id="p-60">In addition to the important identification of RUVBL1 as a candidate for the development of an MYC-based cancer therapy, several further observations emerged from this study. First, we found that the dependence of pancreatic cancer cells on specific MYC binding partners differs dramatically when grown in culture or in vivo. About one-third of all tested MYC binding partners were essential for KPC cells in culture but dispensable for the same cells when growing in their natural environment in mice. Some of these proteins are currently targets of drug development campaigns, such as YY1, p400 and RAD21. We speculate that unnatural metabolite conditions and the absence of stromal cells in culture generate artificial dependencies. On the other hand, the settings of our in vivo screen could also create artificial dependencies, such as the immunogenicity of transgenes and the use of doxycycline for shRNA activation. Overall, our results highlight the need to complement the available results of genome-wide screens in cancer cell line panels<a id="xref-ref-36-2" class="xref-bibr" href="#ref-36">36</a> with genetic screens in intact organisms. However, our in vivo screen did not only devalidate target candidates but also confirmed proteins as promising cancer targets. One prominent example is WDR5, which was one of the few tested MYC binding partners with an even greater dropout in pancreatic tumours than in cultured KPC cells. WDR5 is considered a druggable cancer target and is being intensively investigated by others.<a id="xref-ref-57-1" class="xref-bibr" href="#ref-57">57–59</a> </p><p id="p-61">Our work also clarified the mechanistic connection between MYC and RUVBL1. It has been shown earlier that MYC recruits the TIP60 complex to chromatin and interacts with the TIP60 components TRRAP and RUVBL1/2<a id="xref-ref-27-1" class="xref-bibr" href="#ref-27">27 52 53</a> via a domain known as MYC Box II, which is essential for MYC’s transforming potential.<a id="xref-ref-29-1" class="xref-bibr" href="#ref-29">29</a> The role of RUVBL1 on MYC-mediated gene regulation was however unclear. To understand the primary effect of RUVBL1 on gene expression, we used the AID system to induce the complete degradation of RUVBL1 within a few hours. The acute depletion of RUVBL1 induced the downregulation of a gene expression profile typical of high, oncogenic MYC expression. In addition, promoters of RUVBL1-activated genes were bound by both MYC and RUVBL1, suggesting direct activation of RNAPII function (see graphical abstract). In contrast, we hypothesise that the regulation of MYC/RUVBL1 repressed genes is indirect, since the promoters of these genes are much less occupied by both proteins. We speculate that in a RUVBL1-proficient situation, RNAPII or RNAPII-associated proteins are recruited to MYC/RUVBL1-bound genes and thus sequestered away from MYC/RUVBL1-negative promoters. Such a squelching mechanism has previously been proposed by us<a id="xref-ref-24-1" class="xref-bibr" href="#ref-24">24</a> and others<a id="xref-ref-60-1" class="xref-bibr" href="#ref-60">60</a> for MYC-mediated gene repression.</p><p id="p-62">This study also demonstrated that the AID system can be used to degrade RUVBL1 in vivo. Previously, this system was shown to degrade GFP reporter proteins in healthy mouse tissues,<a id="xref-ref-48-2" class="xref-bibr" href="#ref-48">48</a> but it was unclear whether it could also be used for target depletion in orthotopic tumours in immune-competent mice. The established auxin depletion system can be used to investigate whether other murine and human PDAC models are similarly dependent on RUVBL1 as the KPC cell model used here. This is necessary because human PDAC tumours are characterised by a high degree of phenotypic and genetic heterogeneity and may therefore show variable dependence on RUVBL1. The auxin system is also ideal for investigating whether the effects of RUVBL1 on transcription are always MYC dependent, since RUVBL2 has been shown to have direct effects on the subnuclear distribution and clustering of RNAPII in mouse embryonic stem cells.<a id="xref-ref-47-2" class="xref-bibr" href="#ref-47">47</a> Overall, we envision that auxin-mediated target depletion, in combination with bioluminescence, will become a powerful tool for future mechanistic and translational studies in mice.</p><p id="p-63">Finally, we observed that tumour regression after RUVBL1 depletion was accompanied by a massive infiltration of CD3-positive immune cells in the KPC model used here. This finding is significant, since both murine and human pancreatic tumours are sparse in immune cells and are therefore considered immunologically ‘cold’.<a id="xref-ref-61-1" class="xref-bibr" href="#ref-61">61</a> Accordingly, most patients with pancreatic cancer do not benefit from immunotherapies such as PD-1/CTLA-4 checkpoint blockade. We speculate that drugs targeting the MYC-RUVBL1 axis could make pancreatic tumours susceptible to immunotherapy. In support of this proposition, four of 11 mice with orthotopic tumours were cured by a combinatorial treatment consisting of transient RUVBL1 depletion and PD-1 checkpoint blockade. Thus, this study has possibly discovered a pharmaceutical strategy to render pancreatic cancers immunologically ‘hot’ and susceptible to immune therapy.</p></div><div class="section methods" id="sec-19"><h2 class="">Methods</h2><div id="sec-20" class="subsection"><h3>Cell lines and animals</h3><p id="p-64">KPC (kindly provided by Jens Siveke, Essen, Germany), 9172, R211 (Kras<sup>G12D/+</sup>, Trp53<sup>R172H/+</sup>), 8661, 6075 (Kras<sup>G12D/+</sup>, classical), 5320, 9091 (Kras<sup>G12D/+</sup>, mesenchymal), 24031, 24033 (Kras<sup>G12D/+</sup>, Cdkn2a<sup>−/−</sup>), SB1551, SB1557 (Kras<sup>G12D/+</sup>, Cdkn2a<sup>−/−</sup>) (kindly provided by Dieter Saur, Munich, Germany), NIH3T3 (RRID:CVCL_0594), A375 (RRID:CVCL_0132), PaTu 8988t (RRID:CVCL_1847) and PANC-1 (RRID:CVCL_0480) cell lines were cultured in DMEM (Thermo Fisher Scientific) supplemented with 10% FBS (Capricorn Scientific), 100 U/mL penicillin and 100 µg/mL streptomycin (Sigma-Aldrich) at 37°C, 5% CO<sub>2</sub>.

Afterwards, each transduced KPC culture was divided into two: in one-half the culture medium was supplemented with 1 µg/mL doxycycline (Sigma-Aldrich) and the other half received an equal volume of ethanol vehicle. The six cultures were subcultured every 2–3 days while maintaining a representation of at least 1000 cells per shRNA construct.

The mice were fed standard chow (ssniff Spezialdiäten) ad libitum, and when mice reached the humane endpoint, they were killed and the tumours were harvested. Reaching the humane endpoint was determined from both signs of reduced well-being (dishevelled fur, blurry eyes, reduced interactions, lethargy) and large tumour size (assessed by bioimaging). Genomic DNA was extracted from tumours and assessed for shRNA representation. The best cell number was then injected into the pancreata of 10 C57BL/6J mice. After 7 days, mice were divided into five pairs based on the size of developed tumours. One mouse of each pair was fed chow containing 625 mg/kg doxycycline (A112D70624, ssniff Spezialdiäten), while the other mouse received standard chow (both, ad libitum).

Briefly, 10 nt (6 nt unique molecular identifier (UMI)+4 nt spacer) were trimmed from the 5' ends of reads (FastqFilter program from the GRAND-SLAM pipeline), and the sequencing adapter (<span class="named-content sequence" id="named-content-1">AGATCGGAAGAGCACACGTCTGAACTCCAGTCA</span>) was trimmed from the 3' end using Cutadapt V.3.4. Next, Bowtie 2 (V.2.3.0) with default parameters was used to discard reads mapping to rRNA (GenBank identifier <a class="external-ref external-ref-type-gen" href="/lookup/external-ref?link_type=GEN&access_num=U13369.1&atom=%2Fgutjnl%2F73%2F9%2F1509.atom">U13369.1</a>) and to verify the absence of <em>Mycoplasma</em> contamination.

Finally, all reads mapping to the same genomic location sharing the same UMI were collapsed, and only mismatches that occurred in the majority of these reads were retained (DedupUMI program of the GRAND-SLAM pipeline). The GRAND-SLAM program was run with parameter –trim 15 against a combined index of murine mRNAs (Ensembl 102) and the ERCC92 spike-ins, to count reads and to estimate the new-to-total RNA ratio for each sample and each mRNA.</p><p id="p-95">The grandR package (version 0.1.11 for the CB-6644 data set, and version 0.1.23 for the auxin data set) was used for quality control and downstream analyses. The absence of cellular toxicity of 4sU was confirmed using the ‘PlotToxicityTestRankAll’ function. Genes were filtered to have at least 50 reads in at least half of the samples. Read counts per sample were normalised by dividing by the size factors (estimateSizeFactorsForMatrix from the DESeq2 R package) computed from either the total number of ERCC92 mapped reads or the total number of murine mRNA mapped reads. Greater within-replicate variability after ERCC92 normalisation indicated that the variance in ERCC spike-ins was greater than in total RNA content of the samples. Therefore, we continued with murine mRNA size factor-normalised counts. Principal component analysis showed an extreme outlier (the third replicate of the 15-hour time point in the auxin data set), which was therefore excluded from further analyses. P values were computed on total or new RNA using the Wald test implemented in DESeq2, and fold changes were estimated using the PsiLFC estimator from the lfc package.</p></div><div id="sec-31" class="subsection"><h3>RNA-seq</h3><p id="p-96">Cells were treated with 1 µM CB-6644 for 24 hours.
