Fig. 9From: Characterization of stemness features and construction of a stemness subtype classifier to predict survival and treatment responses in lung squamous cell carcinomaValidation of the expression of hub genes using qRT-PCR. A The expression levels of nine hub genes in tumor and normal tissues in TCGA dataset. B The expression levels of COL3A1, EFEMP2, EHD2, FSTL3 and ALOX5 in 10 paired LUSC tumor and adjacent normal tissues were quantified by qRT-PCR. * p < 0.05, ** p < 0.01, *** p < 0.001Back to article page
