Epigenetic and oncogenic inhibitors cooperatively drive differentiation and kill KRAS-mutant colorectal cancers [LOVO_BCat]

Project description:Current treatments for KRAS-mutant colorectal cancers (CRCs) are often limited by cellular plasticity and rewiring responses. Here we describe a promising therapeutic strategy that simultaneously targets epigenetic and oncogenic signals. Specifically, we show that inhibitors of the histone methyltransferase, EZH2, synergize with various RAS pathway inhibitors and promote dramatic tumor regression in vivo. Together these agents cooperatively suppress WNT-driven transcription and drive CRCs into a more differentiated cell state by inducing the Groucho/TLE corepressor, TLE4, along with a network of WNT pathway inhibitors and intestinal differentiation proteins. However, these agents also induce the pro-apoptotic protein BMF, which subsequently kills these more differentiated cells. Accordingly, cell death can be prevented by activating β-catenin, blocking differentiation, or by ablating BMF expression. Collectively, these studies reveal a new therapeutic approach for treating KRAS-mutant CRCs and illustrate a critical convergence of EZH2 and RAS on oncogenic WNT signals, intestinal differentiation, and apoptosis.

A pan-KRAS inhibitor and its derived degrader elicit multifaceted anti-tumor efficacy in KRAS-driven cancers [scRNA-seq]

Project description:KRAS is the most frequently mutated oncogene in human cancers, but to date, only KRASG12C inhibitors have been FDA-approved. Small-molecule inhibitors that target other more prevalent KRAS mutations are in urgent clinical need. Here, we report a highly potent pan-KRAS inhibitor, MCB-294, that selectively targets KRAS, but not HRAS or NRAS. Molecular profiling studies show that MCB-294 binds to and inhibits several KRAS mutants, including G12D, G12C, G12V, thereby disabling KRAS oncogenic signaling. MCB-294 is well tolerated in mice and exhibits remarkable therapeutic efficacy against the growth of a comprehensive range of KRAS-driven cancer cell lines, patient-derived organoids, and tumor xenografts and prolongs mouse survival. By employing an MCB-294 derivative as the KRAS binder, we further identify a VHL-based pan-KRAS degrader, MCB-36, that efficiently degrades KRAS in vitro and in vivo through the ubiquitin-proteasome system. Importantly, MCB-294 and MCB-36 not only effectively kill KRASG12C inhibitor-resistant cells, but also reshape the tumor microenvironment by boosting T cell-mediated anti-tumor immunity. Taken together, our findings demonstrate a successful and feasible strategy for targeting pan-KRAS to impair multifaceted features of KRAS-driven cancers.

A proteomic and phosphoproteomic landscape of KRAS mutant cancers identifies combination therapies

Project description:KRAS mutant cancers, which feature the activation of multiple phosphorylation signaling pathways, remain a major challenge for cancer therapy. This study provides a landscape of the proteomics and phosphoproteomics of KRAS mutant cancers by analyzing different KRAS mutant human cancer cell lines across different tissues types. By integrating multi-omics analysis, we identify different robust subsets, which recapitulate the histological, pathological and prognostic features of human cancers.
