The changes enable cGAS to retain chromatin longer upon DNA damage by weakening TRIM41-mediated ubiquitination and interaction with the segregase P97. Prolonged chromatin binding of cGAS enhanced the interaction between repair factors FANCI and RAD50 to facilitate RAD50 recruitment to damage sites, thereby potentiating homologous recombination repair.

Selectively blocking the RAS-PI3Kα interaction may represent a strategy for treating RAS-dependent cancers as it would avoid the toxicity associated with inhibitors of PI3Kα lipid kinase activity. We developed compounds that bind covalently to cysteine 242 in the RBD of PI3K p110α and block RAS activation of PI3Kα activity. In mice, inhibitors slow the growth of RAS mutant tumors and Human Epidermal Growth Factor Receptor 2 (HER2) overexpressing tumors, particularly when combined with other inhibitors of the RAS/Mitogen-activated protein kinase pathway, without causing hyperglycemia. Oncogenic mutations in the small guanosine triphosphatase RAS occur in 20% of human cancers, with RAS proteins activating both the mitogen-activated protein kinase (MAPK) and Phosphoinositide 3-kinase (PI3K) pathways ( <jats:xref ref-type=\"bibr\"> <jats:italic toggle=\"yes\">1</jats:italic> </jats:xref> – <jats:xref ref-type=\"bibr\"> <jats:italic toggle=\"yes\">3</jats:italic> </jats:xref> ).
