SLC7A11 and carcinoma: Finally, The immunocytochemical staining with anti-CCDC6 (HPA019051) and anti-xCT/SLC7A11 antibodies in the Embryonal Carcinoma NTERA-2 cells and in murine testicular cells, wild type or engineered for CCDC6 depletion or overexpression, showed that the expression of CCDC6 and xCT/SLC7A11 proteins inversely correlated, as also appreciated by western blot analysis performed with the same antibodies (Fig. 7).
