The aim is to investigate how KRAS signaling intensity affects pancreatic ductal adenocarcinoma (PDAC) initiation, progression, and response to treatment.
Developed mouse models with varying KRAS signaling levels by crossing specific genetically modified mice.
Assessed tumor onset, metastasis, and survival in these models.
Classified human PDAC cell lines based on KRAS signaling intensity and evaluated their response to the pan-RAS inhibitor RMC-6236.
Mice with high KRAS signaling developed PDAC significantly earlier than those with low signaling.
Median survival time was 8 weeks for high KRAS, 23 weeks for intermediate, and 41 weeks for low signaling.
Higher KRAS signaling levels correlated with increased distant metastasis to the lung and liver.
Cells with lower KRAS signaling were more sensitive to RMC-6236, indicating potential for patient stratification.
