ABSTRACT
BACKGROUND:
Although nucleotides -like Adenosine Triphosphate (ATP) and its derivatives Adenosine, were known to induce growth inhibition and apoptosis in diverse cell lines, little is known about their effects on trophoblast.OBJECTIVE:
To elucidate the effects of extracellular ATP and adenosine on trophoblast cell growth and to delineate if apoptosis is involved in this mechanism. MATERIALS ANDMETHODS:
We used TL cell line, derived from human term placenta. The cells were cultured for 24, 48, and 72 hours after being treated with ATP and adenosine, each. Also, cell growth according to different concentrations of ATP and adenosine was evaluated. To test whether apoptosis was induced by each nucleotide, DNA fragmentation and nuclear condensation by Hoechst 33258 stain and P53 protein expression were evaluated.RESULTS:
Cell growth was inhibited by ATP and adenosine in time and dose-dependent manner. Furthermore, the growth inhibitory effect of adenosine was stronger than ATP, whereas signs of DNA fragmentation and nuclear condensation were observed in ATP treated cells, but not in adenosine treated ones.CONCLUSION:
Our results shows that ATP and adenosine exert inhibitory effect on growth in TL cell line. These findings suggest that pathological production of ATP or its metabolites, adenosine, may lead to a pathologic status such as preeclampsia or intrauterine growth restriction.
