SCGB1D2 and breast carcinoma: To our knowledge, few papers have investigated the functional role of LipB overexpression in cancer cells: Sjodin et al. demonstrated that ectopic overexpression of lipophilin B did not affect the cell proliferation rate of breast carcinoma cells in vitro [37], while Tucker et al. reported that it does not appear to mediate chemoresistance to the estradiol derivative estramustine in hormone refractory prostate cancer [38].
