Effects of MEL and UVB on cell viability in HaCaT cells. (A) HaCaT cell viability was assayed by an MTT assay after various concentrations of MEL-A incubation for 0, 0.625, 1.25, 2.5, 5, 10, 20, 40 or 80 μg/mL. (B,C) HaCaT cells were treated with different doses of MEL-B and MEL-C for 24 h and their cell viability. (D) Effect of different exposure intensities of UVB on cell viability in HaCaT cells. Values are expressed as means ± SD (n = 3). * p < 0.05, **** p < 0.0001 vs. control group (Ctrl).
