Cell-cycle analysis was performed using flow cytometry, and mRNA levels of p16, p21 and p53 were detected by a reverse transcription-polymerase LMTK2 chain reaction (RT-PCR), and protein levels were detected using Western blot analysis. Results: Five types of traditional Chinese medicine attenuated UVB-induced G1 growth arrest. The mRNA and protein levels of p16, p21 and p53 in HaCaT cells and dermal fibroblasts increased after UVB irradiation, but pretreatment with five types of traditional Chinese medicine decreased the expression of p16, p21 and p53. Conclusions: These results indicated that five types of traditional Chinese medicine can attenuate G1 growth arrest of HaCaT cells and dermal fibroblasts induced by UVB exposures, which was caused by down-regulating the expression of cell-cycle regulatory proteins p16, p21 and p53. ""Vitiligo is an autoimmune depigmentation disorder, commonly associated with systemic autoimmune diseases. Deficient serum 25-hydroxyvitamin D (25(OH)D) levels have been noted in some patients with autoimmune diseases. To evaluate serum 25(OH)D levels in vitiligo patients with and without systemic autoimmune diseases. Romidepsin price A case-control study was conducted on 40 vitiligo patients (20 patients with systemic autoimmune diseases and 20 patients without autoimmune diseases) and 40 age-, gender- and skin phototype-matched healthy controls. Serum 25(OH)D was measured in all subjects, divided into: normal or sufficient (��?30?ng/ml), insufficient (?20?ng/ml) and deficient (��?20?ng/ml) levels. One patient with vitiligo (2.5%) versus 33 healthy controls (82.5%) have sufficient serum 25(OH)D levels while 39 patients (97.5%) versus 5 controls (12.5%) have U0126 purchase deficient 25(OH)D levels with significantly lower serum 25(OH)D levels in patients compared to controls (P-value?
