Abstract B083: Mutant KRAS cooperates with the hypoxic tumor microenvironment to drive immunosuppressive macrophages via a paracrine PGE2/GM-CSF axis

Hypoxia is known to drive an immunosuppressive microenvironment in pancreatic ductal adenocarcinoma (PDAC). However, the underlying immunosuppressive mechanisms remain unclear. Here, we hypothesized that hypoxia-induced factors secreted from tumor cells promoted immunosuppressive macrophages in PDAC. We tr...

Targeting AXL Overcomes Adaptive Resistance to KRAS Inhibition in KRAS-Driven Cancer

By integrating adaptive response to KRAS inhibition with anti-tumor immunity, AXL represents a mechanistically actionable vulnerability whose inhibition deepens and prolongs responses to both allele-specific and pan-KRAS-targeted therapies.
