Galectin-7 regulates ΔNp63 expression through miR-203. (a) The p63 protein levels; (b) The galectin-3, galectin-7, p63, and keratin-1 protein levels; (c) Immunofluorescence of p63; and (d) The relative ratio of p63-positive cells in galectin-7 and miR-203 knockdown cells after normalization to parental cells are presented. The statistical analyses were performed in triplicated experiments by individually comparing with the HaCaT parental cells, *P < 0.05, **P < 0.01, ***P < 0.001. Scale bar = 200μm. (e) The relative ratio of p63-positive cells in transfected galectin-7 knockdown cells (sh-1) by indicated plasmids was normalized to sh-1 cells. The statistical analyses were performed by individually comparing with the galectin-7 knockdown cell line (sh-1), ns: not significant, **P < 0.01. (f) The p63 protein levels of transiently transfected HaCaT cells.
