• RITA: Separating Growth Arrest from Cell Death

  2026-09-14

  RITA (NSC 652287) is a p53-pathway research compound with pronounced activity in renal carcinoma models. This article explains how to interpret its effects by separating proliferation arrest, cell death, DNA damage, and tumor regression rather than relying on a single viability endpoint.

• ZK53 Activates ClpP to Arrest Lung Cancer

  2026-09-14

  This Nature Communications study identifies ZK53 as a selective activator of human mitochondrial ClpP and shows that uncontrolled mitochondrial proteolysis suppresses oxidative phosphorylation, activates ATM-mediated DNA damage signaling, and arrests lung squamous cell carcinoma growth. Its structure-guided and in vivo evidence establishes a mechanistic bridge between mitochondrial proteostasis and cell-cycle control, while also defining experiments needed to test whether ATM signaling is required for the response.
