Mutations in the Rat Sarcoma Virus Oncogene Homolog (RAS) protein occur in approximately 20% to 30% of cancer cases, and is the most common mutated oncogenes in pancreatic cancer, colorectal cancer, and non-small cell lung cancer. RAS proteins function as molecular switches, activated when bound to Guanosine-5′-triphosphate (GTP) and deactivated when bound to Guanosine-5′-diphosphate (GDP). Mutations in RAS proteins impair their ability to hydrolyze GTP with GTPases, causing the molecular switch to remain persistently active in the GTP-bound state. This drives unchecked downstream oncogenic signaling, such as through the RAS-Rapidly Accelerated Fibrosarcoma kinase (RAF)-MAPK/ERK Kinase (MEK)-Extracellular Signal-Regulated Kinase (ERK) pathway and the RAS-Phosphoinositide 3-Kinase (PI3K)-Phosphoinositide-Dependent Kinase-1 (PDK1)-Protein Kinase B (AKT) pathway, thereby promoting the survival and proliferation of cancer cells.
Son of Sevenless Homolog 1 (SOS1) protein is a Guanine Nucleotide Exchange Factor (GEF) that has been shown to catalyze the binding of Kirsten Rat Sarcoma Viral Oncogene Homolog (KRAS) to GTP, thereby facilitating the activation of KRAS. Consequently, the targeted inhibition of SOS1 protein and the SOS1-KRAS interaction, regardless of the specific KRAS mutation, emerges as a promising therapeutic target for cancer treatment. Furthermore, research has demonstrated that the combination of MEK inhibition can lead to profound pathway blockade and tumor regression in vivo, presenting a potential approach to treating a majority of KRAS-driven cancers.
