ST6Gal-I expression in OV4 ovarian cancer cells. OV4 cells that have no endogenous ST6Gal-I were stably transduced with either empty vector or ST6Gal-I-expressing lentivirus. ST6Gal-I expression was confirmed by immunocytochemistry (A) and immunoblotting (B). ST6Gal-I localization to the Golgi is shown by co-localization with the Golgi marker GM-130 in the ST6Gal-I forced expression line (C) Par = parental; EV = empty vector; ST6 = cells with forced ST6Gal-I expression.
