| Sumario: | Cellular senescence: SMARCD1, a key molecule in lipid accumulation A team led by Yoshinori Katakura at Kyushu University tried to clarify the molecular mechanisms of pathogenesis of fatty liver, focused on SMARCD1, one of the identified senescence-associated genes, and revealed its pivotal roles in cellular senescence induction and lipid accumulation in hepatocytes. SMARCD1 is a member of the SWI/SNF chromatin remodeling complex family and known to regulate the transcription of target genes through the alteration of chromatin structure. The results obtained here suggest that dietary imbalance such as high-fat diet impaires expression of SMARCD1, which triggers cellular senescence and lipid accumulation in hepatocytes, indicating a potential role of SMARCD1 in the prevention of lifestyle-related diseases. |
