Application of histone H3K18 lactic acid modification related target in preparation of medicine for preventing or treating atherosclerosis

PendingCN121868497Aclearly targetedIntervention path is clearOrganic active ingredientsCardiovascular disorderArteriolePharmaceutical Substances
The invention relates to an application of a histone H3K18 lactic acid modification related target in preparation of a medicine for preventing or treating atherosclerosis. The invention belongs to the field of biological medicine, and discloses histone acetyltransferase P300 and application of histone H3K18 lactylation (H3K18la) modification mediated by the histone acetyltransferase P300 as a new target spot for treating atherosclerosis (AS). Researches find that in the AS process, lactic acid accumulation in vascular smooth muscle cells (VSMCs) up-regulates H3K18la through P300 catalysis, and then the pathological phenotype of the VSMCs is induced, and plaque development is promoted. H3K18la can be reduced and the phenotype can be improved by inhibiting LDHA and MCT1 in vitro or knocking out a P300 gene; the P300 for in-vivo targeted inhibition of the VSMCs can significantly reduce the artery plaque. Therefore, the P300 and H3K18la inhibitors can be used for preparing the anti-atherosclerosis medicine.
