SHP2 inhibition prevents adaptive resistance to MEK inhibitors in multiple cancer models

C Fedele, H Ran, B Diskin, W Wei, J Jen, MJ Geer… - Cancer discovery, 2018 - AACR
Adaptive resistance to MEK inhibitors (MEKi) typically occurs via induction of genes for
different receptor tyrosine kinases (RTK) and/or their ligands, even in tumors of the same …

Shipping out MEK inhibitor resistance with SHP2 inhibitors

P Torres-Ayuso, J Brognard - Cancer discovery, 2018 - AACR
RAS is one of the most frequently altered oncogenes, yet RAS-driven tumors are largely

The Q61H mutation decouples KRAS from upstream regulation and renders cancer cells resistant to SHP2 inhibitors

T Gebregiworgis, Y Kano, J St-Germain… - Nature …, 2021 - nature.com
Cancer cells bearing distinct KRAS mutations exhibit variable sensitivity to SHP2 inhibitors
