Pancreatic cancer is one of the most deadly cancers affecting Western world. Because disease highly metastatic and difficult to diagnosis until late stages, 5-y survival rate around 5%. The identification molecular drivers critical for furthering our understanding development improved diagnostic tools therapeutics. We have conducted a mutagenic screen using Sleeping Beauty ( SB ) in mice identify new candidate genes pancreatic cancer. By combining with an oncogenic Kras allele, we observed...

High spliceosome activity is a dependency for cancer cells, making them more vulnerable to perturbation of the splicing machinery compared normal cells. To identify factors important prostate (PCa) fitness, we performed pooled shRNA screens in vitro and vivo. Our identified heterogeneous nuclear ribonucleoprotein M (HNRNPM) as regulator PCa cell growth. RNA- eCLIP-sequencing HNRNPM binding transcripts key homeostatic genes. its targets prevents aberrant exon inclusion backsplicing events. In...

Large-scale oncogenomic studies have identified few frequently mutated cancer drivers and hundreds of infrequently drivers. Defining the biological context for rare driving events is fundamentally important to increasing our understanding druggable pathways in cancer.

The p53 transcription factor modulates gene expression programs that induce cell cycle arrest, senescence, or apoptosis, thereby preventing tumorigenesis. However, the mechanisms by which these fates are selected unclear. Our objective is to understand target selection and, thus, enable its optimal manipulation for cancer therapy. We have generated targeted transgenic reporter mice in EGFP driven transcriptional activity at a response element from either p21 Puma promoter, induces...

The tumour suppressor p53 is regulated primarily at the protein level. In normal tissues its levels are maintained a very low level by action of specific E3 ligases and ubiquitin proteosome pathway. mutant contributes to transformation, metastasis drug resistance. High can be found in tumours accumulation has previously been reported pathologically cells human skin. We show for first time that similarly elevated detected apparently knock-in mouse model. fact, small intestine, spontaneously...

Cancer driver prioritization for functional analysis of potential actionable therapeutic targets is a significant challenge. Meta-analyses mutated genes across different human cancer types has reaffirmed the role major players in cancer, including KRAS, TP53 and EGFR, but had limited success prioritizing with non-recurrent mutations specific types.

Transposon-based insertional mutagenesis in the mouse provides a powerful approach for identifying new cancer genes. Transposon insertions genes are selected during tumor development because of their positive effect on growth, and transposon insertion sites tumors thus serve as tags Direct comparisons transposon-mutated with mutated human can lend insight into signaling pathways that drive tumorigenesis. This is critical prioritizing further study, either efficacy biomarkers or drug targets....

<h3>Background</h3> Overall, 30% of human cancers are driven by mutant RAS proteins, which have historically been difficult to target. While immunotherapy is effective for <i>NRAS</i>-mutant melanoma, resistant disease inadequately addressed, and <i>KRAS</i>-driven carcinomas much less responsive. Oncogenic pathways often key targets inhibition. Even so, resistance the inability safely combine these approaches with immunotherapies remain major challenges. The idea oncogenic pathway agonism...
