ETS1, Mitophagy, and BPD: SENP2/HSPA8/FUNDC1
2026-08-13
The reference study identifies ETS1 as a transcriptional regulator that protects against hyperoxia-associated bronchopulmonary dysplasia by suppressing excessive mitochondrial damage-induced mitophagy. Its mechanistic contribution is the definition of an ETS1–SENP2–HSPA8–FUNDC1 pathway in which FUNDC1 deSUMOylation promotes chaperone-dependent degradation, linking transcriptional control with mitochondrial quality control.

SmD2 Acetylation Links Splicing to PARP Sensitivity
2026-08-10
The 2024 Nature Communications study identifies acetylation-dependent control of the spliceosome protein SmD2 as a mechanism connecting alternative splicing, DNA-damage repair, and PARP-inhibitor response in hepatocellular carcinoma. Its data support combined HDAC2-directed modulation and olaparib as a preclinical strategy, while also positioning SmD2 and BRCA1/FANC cassette-exon regulation as mechanistic biomarkers for further investigation.
