Fig. 3. Effects of carnosine and ROL on HAS protein expression in NHEKs. Western blot analysis was performed to evaluate HAS expression after 24 h and 48 h treatment with carnosine and ROL individually or in combination. NHEKs were cultured in 6-well plates, and protein extraction was conducted. Values represent the mean expression ± standard deviation (SD) (n=3). *p≤0.05 vs. vehicle control; **p≤0.01 vs. vehicle control; #p≤0.05 vs. ROL 10 μM and ##p≤0.01 vs. ROL 10 μM.
