Özet

The first of our aims in this study was to investigate the effects of 5-HT2AR, 5-HT7R, and A2AR blockades on miR-27b-3p expression in the short and long-term in neuroblastoma cells. Our second aim was to reduce the expression of pERK and suppress proliferation by blocking the 5-HT2AR with ketanserin. Our third aim was to reduce the expression of pAKT and induce apoptosis by blocking the A2AR and 5-HT7R with MSX3 and SB269970. Thus, we aimed to investigate the therapeutic efficacy of ketanserin, MSX3 and SB269970, individually or in combination, on neuroblastoma cells. We found that short and long-term blockades of A2A, 5-HT2A, and 5-HT7 receptors had different effects on miR-27b-3p expression. Blockade of A2AR and 5-HT7R with MSX3 and SB269970 decreased miR-27b-3p expression in the short term while increasing it in the long term. Ketanserin increased miR-27b-3p expression in both the short and long term. When 5-HT2AR was blocked with ketanserin, no significant difference was observed in pERK expression and proliferation in the short term. In contrast, a substantial decrease in pERK expression and proliferation was detected in the long term. Our findings show that the MSX3 + SB269970 dual combination and ketanserin + MSX3 + SB269970 triple combination are especially critical in suppressing pAKT expression in the long term. These findings showed that pAKT protein expression induced apoptosis due to decreased in neuroblastoma cells. Our study provides the first evidence for the relationships between ketanserin/miR-27b-3p/pERK, MSX3/miR-27b-3p/pAKT, and SB269970/miR-27b-3p/pAKT in neuroblastoma cells. Ketanserin, MSX3, and SB269970 drug combinations may be promising therapeutic agents in neuroblastoma cells.
