Further assessment of Salvia haenkei as an innovative strategy to counteract skin photo-aging and restore the barrier integrity
Figure 6. Effect of Salvia haenkei extract 0.01-0.1 and 1 μg/ml on Sirtuin-1 protein expression in HaCaT cells exposed and not exposed to UVB radiation (30 KJ/m2). Results are normalized to calnexin, expressed as a ratio of treatment vs control not exposed to UVB [+ UVB/ (ctr - UVB)], and are the mean ± SEM of 4 independent experiments. *p < 0.05, **p < 0.01, ***p < 0.001 treatment vs control-UVB; §p < 0.05, treatment vs control+UVB.
