Fig. 5From: Human epithelial-type ovarian tumour marker beta-2-microglobulin is regulated by the TGF-β signaling pathwayMeasurement of B2M concentration after TGF-β1 treatment. The concentration of B2M in the cytosol and culture medium of OVCAR-3 and SK-OV-3 cells in the absence (−) or presence (+) of 10 ng/ml TGF-β1 for 72 h (a) and 24 and 48 h (b), respectively, was determined by the ELISA assay. *P < 0.05Back to article page
