DNA sensing and Interferon Beta 1 transactivation drive radiation-induced anti-tumor immune effects in human pancreatic cancer cells
We demonstrate that a clinically relevant X-ray hypofractionation regimen (3x8 Gy) of multiple PDAC cel lines effectively induces immunogenic cell death and transactivates Interferon beta-1 in a STING-dependent manner. RNA-seq analyses showed a global and steady upregulation of type I interferon response in PDAC cells following 3x8 Gy.
