Research Abstract |
We have previously reported that histone H1 disappears and HMGA proteins are increased in cellular senescent cells. In this study, we further examined the structure and function of the nucleus in senescent cells. We found that 1) histone H1 is likely degraded via the ubiqutin-proteasome pathway, 2) the NF-kB pathway is involved in inducing the characteristic gene expression profiles in senescent cells, and 3) the nuclear membrane is structurally and biochemically dysfunctional. These results will provide a means to control the senescence phenotypes.
