Abstract     [Buy Article]
    Chronic exposure to atrazine (ATR) raises concerns about adverse effects on reproductive functions. We tested our previously validated filtering device, the OBP-based filter, onto a biological model constituted of cultured swine granulosa cells treated for 48 h with media conditioned with 0.1 or 10 micrometre ATR evaluating cell viability and steroidogenesis. The tested atrazine concentrations did not change granulosa cell viability and no filtering effects was observed following treatments with media prepared with differently filtered water. As for steroidogenesis, treatment of water with OBP -based filter containing 10 micrometre atrazine completely suppressed the stimulatory effect of 10 micrometre atrazine on progesterone production as well as the inhibitory effect of 0.1 micrometre ATR on estradiol-17 production by granulosa cells. Our data demonstrate that the impairment of steroidogenesis induced by ATR is effectively removed after water filtration in the experimental device thus suggesting potential use in biotechnological applications on living cells and/or organisms.
