Potential role of Bcl2 in lipid metabolism and synaptic dysfunction of age-related hearing loss


ABSTRACT: Age-related hearing loss (ARHL) is a prevalent disease that affects millions of people worldwide. BCL-2 gene plays a tremendous role in cellular senescence, and it was confirmed that the BCL-2 family is closely associated with neurological disorders and ARHL. In addition to modulating apoptosis and oxidative stress, as well as other effects, this study we report here that BCL-2 plays a crucial position in regulating phospholipid and lipid metabolism in the developing cochlear tissues of rats and a sensory epithelial cell line(OC1), including the cholesterol synthesis pathway that is differentially expressed by genes such as LSS,NSDHL, and CYP51, which further demonstrates the mechanism of the action of BCL-2 in hair cells. In conclusion our data provide a new molecular framework for the regulatory mechanism of BCL-2 down-regulation in senescent cells. These findings provide valuable insights into the molecular mechanisms of ARHL and may set the stage for new therapeutic approaches for this prevalent age-related disease.
