The NF1 tumor suppressor regulates PD-L1 and immune evasion in melanoma

Abstract excerpt

Hotspot BRAF, hotspot NRAS, and NF1 loss-of-function mutations are found in approximately 50%, 25%, and 15% of cutaneous melanomas, respectively. Compared to mutant BRAF and NRAS, the role of NF1 loss in melanoma remains understudied. NF1 has a RAS GTPase-activating protein (GAP) function; however, studies also support NF1 RAS-independent tumor-suppressor functions. Recent reports indicate that patients with NF1...
