Antitumor effect of a small-molecule inhibitor of KRASG12D in xenograft models of mucinous appendicular neoplasms

373 views | Jan 25 2024

The profound inhibition of tumor growth in a high-grade PMP xenograft mouse model carrying a KRASG12D mutation by the small-molecule KRASG12D inhibitor MRTX1133 underscores its potent efficacy and supports its potential for clinical translation in treating PMP. [Read the Full Post]

CRISPR screening identifies mechanisms of resistance to KRASG12C and SHP2 inhibitor combinations in non-small cell lung cancer

338 views | Jan 23 2024

The study uncovers that while KRASG12C inhibitors initially exhibit promising responses, combining them with SHP2, PI3K, and CDK4/6 inhibitors extends regression in preclinical models, yet resistance emerges via KRASG12C amplification and MAPK/PI3K pathway alterations, with FGFR1 loss sensitizing and PTEN loss rescuing against the KRASG12C/SHP2 inhibition.
