Figure 4. miR-23a downexpression suppressed the PUVA- and UVB-induced SIPS.
a. The G1 arrest was examined in the Ant-23a- or Ant-CNT-transfected cells with or without UV irradiation. b., c. The relative protein levels of p53, p16, and p21 were examined in the Ant-23a- or Ant-CNT-transfected cells with or without UV irradiation (n = 3). Actin was used as a loading control. The p53/Actin, p16/Actin, and p21/Actin densitometric ratios were marked (3 independent experiments gave similar results. See Figure S3).
