Aldehyde Dehydrogenase 2 Lactylation Aggravates Mitochondrial Dysfunction by Disrupting PHB2 Mediated Mitophagy in Acute Kidney Injury.

Mitochondrial dysfunction is a crucial event in acute kidney injury (AKI), leading to a metabolic shift toward glycolysis and increased lactate production. Lactylation, a posttranslational modification derived from lactate, plays a significant role in various cellular processes, yet its implications in AKI remain underexplored. Here, a marked increase in lactate levels and pan-Kla levels are observed in kidney tissue from AKI patients and mice, with pronounced lactylation activity in injured proximal tubular cells identified by single-cell RNA sequencing.

Targeting histone methylation and demethylation for non-alcoholic fatty liver disease.

Non-alcoholic fatty liver disease (NAFLD) is the leading chronic liver disease worldwide, facing increasing challenges in terms of prevention and treatment. The methylation of lysine and arginine residues on histone proteins is dynamically controlled by histone methyltransferases (HMTs) and histone demethylases (HDMs), regulating chromatin structure and gene transcription. Mutations, genetic translocations, and altered gene expression involving HMTs and HDMs are frequently observed in NAFLD.

Targeting DNA methyltransferases for cancer therapy.

DNA methyltransferases (DNMTs) play a crucial role in genomic DNA methylation. In mammals, DNMTs regulate the dynamic patterns of DNA methylation in embryonic and adult cells. Abnormal functions of DNMTs are often indicative of cancers, including overall hypomethylation and partial hypermethylation of tumor suppressor genes (TSG), which accelerate the malignancy of tumors, worsen the condition of patients, and significantly exacerbate the difficulty of cancer treatment.
