Functional characterization of genetic alterations is a prerequisite for pancreatic cancer precision medicine. Here, using in vivo CRISPR screens, the authors integrate human cancer genomics and mouse models, identifying that loss of USP15 or SCAF1 accelerates tumor development and leads to reduced inflammatory responses and increased sensitivity to PARP inhibition and Gemcitabine.

| Open AccessCancer-associated Histone H3 N-terminal arginine mutations disrupt PRC2 activity and impair differentiation
Missense mutations in histones can drive oncogenesis and disrupt chromatin, but the associated mechanisms for many such mutations remain poorly understood. Here, the authors show that cancer-associated histone mutations at arginines in the H3 N-terminal tail disrupt repressive chromatin domains, alter gene expression, and in one case impair differentiation via reduction of PRC2 function.

| Open AccessMixed responses to targeted therapy driven by chromosomal instability through p53 dysfunction and genome doubling
Mixed responses to targeted therapy within a patient are a clinical challenge. Here the authors show that TP53 loss-of-function cooperates with whole genome doubling which increases chromosomal instability. This leads to greater cellular diversity and multiple routes of resistance, which in turn promotes mixed responses to treatment.
