Abstract:The activation of RAS signaling has been shown to act as the driver of both de novo and relapsed, chemotherapy resistant acute lymphoblastic leukemia (ALL). Full RAS transformation requires the activity of the small RAS-related C3 botulinum toxin substrate (RAC) protein family, including the hematopoietic-specific RAC2 GTPase and we have previously demonstrated the role of RAC in specific leukemia types. Even though relapsed ALL patients have a 34% overall prevalence of RAS-activating mutations, KRASG12C mutat… Show more
