Steroid hormones modulate galectin-1 in the trophoblast HTR-8/SVneocell line

Bojić-Trbojević Žanka, Božić Milica, Vićovac Ljiljana

The effects of steroids on galectin-1 (gal-1) were studied in HTR-8/SVneo cells by immunocytochemistry, cell-based ELISA, the MTT proliferation test and the Matrigel TM invasion test. Dexamethasone (DEX), progesterone (PRG), and mifepristone (RU486) were used. Gal-1 was modulated in a steroid- and dose-dependent manner by DEX, which mildly but significantly stimulated production at low concentrations (0.1-10 nM), and inhibited it at 100 nM, while the effects of PRG and RU486 were opposite. HTR-8/SVneo cell invasion of Matrigel was significantly decreased in the presence of DEX and lactose. The obtained data support the proposed regulatory role of steroids in trophoblast gal-1 production.
