With the development of research,the mechanism of cell aging has been investigated in molecular level. Two hypotheses have emerged to explain the reason that lamins contribute to cell aging,one is the mechanical stress hypothesis,the other is the gene expression hypothesis. The latter proposes that mutations in A-type lamins lead to abnormal tissue-specific gene regulation. In recent years,the molecular mechanisms of lamins causing cell aging primarily include gene mutation,Zmpste24 mutation,CAAX mutation and other mutations. These mutations in the gene that encode nuclear lamins cause nuclear lamina damage directly and result in cell aging,which have been associated with several degenerative disorders.展开更多
