Caveolin-1, a 21-24 kDa integral membrane protein, is a principal structural component of caveolae in vivo. To investigate the roles of caveolin-1, we established stable transfectants in Hs578T breast adenocarcinoma cells that had up- and down-regulated caveolin-1 expression. In the paper, we demonstrated that caveolin-1 overexpression in Hs578T cells significantly reduced staurosporine-induced apoptosis and the levels of caveolin-1 expression positively correlated with the number of colonies and colony size in soft agar. Our findings indicate for the first time in Hs578T cells that caveolin-1 might play a pivotal role in regulating apoptosis as a suppressor rather than a facilitator through inhibition of neutral-sphingomyelinase, decrease of ceramide, furthermore, activation of Akt signaling pathway.
