Hedgehog signaling is involved in acquired resistance to KRASG12C inhibitors in lung cancer cells

Description: Article states that although KRASG12C inhibitors have shown promising activity in lung adenocarcinomas harboring KRASG12C, acquired resistance to these therapies eventually occurs in most patients. The authors report that the hedgehog signal is induced by KRASG12C inhibitors and mediates KRAS re-expression in cancer cells treated with a KRASG12C inhibitor.
