PDHA1 Succinylation and α-KGA Immune Escape

2026-09-07

A 2025 Nature Communications study identifies PDHA1 lysine 83 succinylation as a metabolic control point in cholangiocarcinoma. The modification increases alpha-ketoglutarate accumulation, activates OXGR1–MAPK signaling in macrophages, suppresses MHC-II antigen presentation, and provides a preclinical rationale for combining succinylation-directed intervention with gemcitabine and cisplatin.

Dual HER2–VEGFR2 Targeting in TNBC Metastasis

2026-09-07

The reference study investigates lapatinib plus Telatinib (BAY 57-9352) in HER2-negative MDA-MB-231 triple-negative breast cancer cells.

Maternal Deltamethrin, Ferroptosis, and Memory

2026-09-05

A 2025 study shows that maternal deltamethrin exposure impairs hippocampal learning and memory in male offspring through a p53-associated SLC7A11/GPX4 ferroptosis pathway. Its integration of behavioral, histological, biochemical, calcium-signaling, and pharmacological evidence offers a useful framework for studying developmental neurotoxicity.

Ether Lipids Shape B Cell Germinal Center Responses

2026-09-04

This study establishes a causal role for B-cell-intrinsic ether lipid biosynthesis in germinal center development, antibody production, and affinity maturation.
