Fig. 1From: miRNA-221 promotes cutaneous squamous cell carcinoma progression by targeting PTENExpression of miR-221 in CSCC tissues and cell lines. a qPCR analysis of miR-221 in tumor and adjacent non-tumor tissues. b Average relative miR-221 level in CSCC cell lines (A431, SCC13, HSC-5 and SCL-1) and the human normal skin cell line HaCaT. Data are means ± SD of three independent experiments. * P < 0.05, compared with controlBack to article page
