Abstract:
Objective To compare the effects of UVA irradiation on cell morphology,quantity and expression of inducible nitric oxide synthase (iNOS) mRNA and protein in human fibroblasts versus a kerati- nocyte cell line HaCaT.Methods Human fibroblasts and HaCaT cells were cultured and irradiated by 5 J/cm~2 UVA.Then,at 24,48 and 72 h after the stimulation,the cell morphology was observed under an in- verted microscope,and iNOS mRNA and protein were measured by RT-PCR and immunohistochemistry method,respectively.Results After the irradiation,human fibroblasts showed shrinkage at the three time points,the quantities of the cells began to decrease significantly at 24 h (P
