USP36–Snail1 Control of Ribotoxic Stress in Cancer
2026-08-18
The reference study identifies a noncanonical nucleolar function for Snail1: after ribotoxic stress, JNK-driven USP36 induction stabilizes nucleolar Snail1, supporting ribosome biogenesis and cancer-cell survival. This mechanism helps explain why homoharringtonine is active in leukemia but relatively ineffective against solid tumors, and it provides a rationale for combination strategies that disrupt the JNK–USP36–Snail1 axis.

PID1, Oxysterols, and Antitumor Macrophage Reprogramming
2026-08-13
The reference study identifies PID1 as an immunometabolic regulator that suppresses LDL uptake and limits the generation of antitumor oxysterols in tumor-associated macrophages. Its findings connect PID1 loss to cholesterol accumulation, reactive oxygen species, 5α,6α-epoxycholesterol and 7β-hydroxycholesterol production, inhibition of mTOR–STAT6 signaling, and improved CD8+ T cell-mediated tumor control.

Sin3L/Rpd3L HDAC Activation by Inositol Phosphates
2026-08-12
Marcum and Radhakrishnan showed that inositol phosphates stimulate HDAC1/2 activity in the conserved Sin3L/Rpd3L complex through the SAP30 zinc finger, a mechanism functionally analogous to—but structurally distinct from—the SANT-domain mechanism found in other HDAC assemblies. Their biochemical, interaction, and NMR experiments also identified RBBP4 as a constitutive activity-enhancing subunit, separating inducible and baseline regulation within one complex.
