SRF protein levels do not change with cellular age. (A) Western blots used equal amounts of protein from young (Y, 36 mean population doublings) and old (O, 82 mean population doublings) Hs68 fibroblasts. Total (Tot) and nuclear (Nuc) extracts and a polyclonal antibody generated against full-length SRF were used. The arrow identifies a 67-kDa band characteristic of native SRF. (B) Young and senescent primary human diploid fibroblasts were fixed and stained with rabbit anti-SRF followed by goat anti-rabbit antibody-Texas Red and counterstained with DAPI to visualize DNA.
