Germicidal lamps using UV-C radiation may pose health safety issues: a biomolecular analysis of their effects on apoptosis and senescence


Figure 4. Analysis of principal pathways involved in senescence, apoptosis, and proliferation by western blot. The histogram shows the quantitative evaluation of western blot bands in HDF, HaCaT, and ARPE-19 after UV exposure with two different lamp sources: Purple Dawn (PD) and HVC2654025-16W (HVC) as indicated. The data are expressed as Arbitrary Units (A.U.) with the mean expression values (± SD, n = three). *p < 0.05; **p < 0.01; ***p < 0.001.
