Abstract:
The influence of hyaluronan (HA) on the expression of human skin fibroblast elastase-type protease (HSFEp) (Homsy et al, 1988) was studied. At confluency of HSF cultures, hyaluronan increased the level of HSFEp in a time and dose-dependent fashion. Optimal effect was observed after 48 h of culture and at 2 mg/ml HA concentration; the stimulatory effect of HA could be suppressed by 1 microM cycloheximide. The enhancement of enzyme biosynthesis by HA was dependent on cell proliferation but quasi invariant with HSF passage number (from 7-21).
