ABSTRACT
Determination the activity of the genes of sirtuin-1, hyaluronidase, TGF-ß cytokine, calreticulin in the process of replicative aging of human fibroblasts in vitro and the effect of hyaluronan preparations with gold nanoparticles on the activity of replicative cell aging. Compared the expression of proteins of the studied genes using specific markers at 7 and 14 passages of cultivation of fibroblasts isolated from human skin, without drugs and in the presence of drugs in the growth medium. This work shows a decrease in the activity of the sirtuin 1 gene and an increase in the expression of hyaluronidase in the process of replicative aging of human fibroblasts. Found a means of slowing down replicative aging by activating the SIRT-1 gene and reducing the activity of hyaluronidase in action in the growth medium of hyaluronan preparations with gold nanoparticles. The discussed variants of cell transitions to the pathological state, caused by replicative aging and the mechanisms of slowing down the replicative aging of human fibroblasts.
