Fumarate hydratase (FH) is a tumor suppressor, but how it acts is unclear. Two reports in this issue of Cancer Cell reveal that FH deficiency leads to succination of Keap1, stabilization of Nrf2, and induction of stress-response genes including HMOX1, which is important for the survival of FH-deficient cells.
琥珀酸脱氢酶(FH)是一种肿瘤抑制因子,但它的作用机制尚不清楚。本期《癌细胞》杂志的两篇报道揭示,FH 缺陷导致 Keap1 的琥珀酰化、Nrf2 的稳定,以及应激反应基因(包括对 FH 缺陷细胞的存活很重要的 HMOX1)的诱导。
