Влияние Р2-рецепторов на цитотоксическое действие цисплатина в культуре клеток рака шейки матки

To investigate the influence of purinergic signalling in squamous cell uterine cervix cancer in vitro, the effect of combining ATP (nonselective agonist P2-receptor) with the nonselective P2 receptor antagonists PPADS (P2Xreceptors), RB2 (P2Y-receptors) and suramin (both P2Yreceptors and P2X-receptors) and the chemotherapeutic drug cisplatin was assessed. ATP effectively reduces up to twofold the growth of uterine cervix cancer cells. RB2 promoted survival of tumor cell by 52,1% compared to the control. Combinations of the cisplatin + ATP demonstrated a strong sensitivity at 2,7 fold. However, this effect of ATP was reversed in the presence of RB2 by 41%. This highlights the potential use of selective P2Y receptor agonists in the treatment of squamous cell uterine cervix cancer
