CLDN4 and FUT4 mRNA and protein expressions in HTR8/SVneo cells. (a) CLDN4 and FUT4 mRNA expressions were reduced by small interfering RNA (siRNA) transfection as measured by qPCR. *P < 0.001; (b and c) CLDN4 and FUT4 protein expressions were reduced by siRNA transfection as measured by western blot (b) and immunocytochemistry staining (c). CLDN4 displayed a primary membrane staining, and FUT4 was a primary cytoplasmic staining. Blue color showed the 4′,6-Diamidino-2-phenylindole (DAPI) nuclear staining; Red color was CLDN4 or FUT4 protein staining. Magnification of images: ×400.
