Revealing ARID1A Function in Gastric Cancer from the Bottom Up.
Overview
abstract
In this issue of Cancer Discovery, Lo and colleagues use CRISPR-based genome engineering in primary human gastric organoids to reveal the functional consequences of ARID1A loss in the early stages of gastric cancer. They show that ARID1A disruption is not tolerated in wild-type organoids, but in the context of TP53 loss, leads to WNT suppression, mucinous metaplasia, enhanced tumorigenicity, and selectively toxicity to BIRC5/Survivin inhibition.See related article by Lo et al., p. 1562.
