NAD+ depletion by type I interferon signaling sensitizes #pancreatic cancer cells to NAMPT inhibition

Emerging evidence suggests that intratumoral interferon (IFN) signaling can trigger targetable vulnerabilities. A hallmark of pancreatic ductal adenocarcinoma (PDAC) is its extensively reprogrammed metabolic network, in which nicotinamide adenine dinucleotide (NAD) and its reduced form, NADH, are critical cofactors. Here, we show that IFN signaling, present in a subset of PDAC tumors, substantially lowers NAD(H) levels through up-regulating the expression of NAD-consuming enzymes PARP9, PARP10, … Continue reading NAD+ depletion by type I interferon signaling sensitizes #pancreatic cancer cells to NAMPT inhibition
