Durable clinical responses to immune checkpoint inhibitors (ICB) remain limited to a minority of patients, and the molecular pathways that modulate ICB efficacy remain incompletely defined. Here we demonstrate that immunotherapy with anti-CTLA-4 and its combination with anti-PD-1 rely on melanoma cell-intrinsic activation of the cytosolic RNA receptor RIG-I. Mechanistically, tumor cell-intrinsic RIG-I...

Summary from the GEO: "Pancreatic adenosquamous carcinoma (PASC) is an aggressive cancer whose mutational origins are poorly understood. An early study reported high-frequency somatic mutations affecting UPF1, a core nonsense-mediated mRNA decay (NMD) factor, in PASC, but subsequent studies did not observe these lesions. The corresponding controversy about whether UPF1 mutations are important contributors...
