Expression of ANXA2, NDRG1 and STAT1 in CaSki and C-4I cells. a The relative mRNA expression was evaluated by RT-qPCR and samples were normalized to the mean of two housekeeping genes, actin and B2M. For each mRNA, results are presented as fold change compared to CaSki cells (n = 3). b Representative Western blot of ANXA2, NDRG1 and STAT1 protein representation in CaSki and C-4I cells. Actin and HSP70 were used as controls. c Representative pictures showing immunolocalization of ANXA2, NDRG1 and STAT1 in CaSki and C-4I cells (magnification 100x)
