Dual inhibition of JAK and MEK suppresses T-cell acute lymphoblastic leukemia induced by mutant IL7R and RASGRP1 overexpression.
Gain-of-function mutant IL-7Rα (mutIL7R) occurs in approximately 10% of patients with Tcell acute lymphoblastic leukemia (T-ALL), an aggressive pediatric cancer. Nearly half of patients with T-ALLs also overexpress RAS guanyl nucleotide exchange factor (RASGRP1), an activator of RAS. Since mutant RAS itself has been sh...
