In the current study, the effects of 7-BIO as a specific GSK3β inhibitor was examined on cell survival and expression of miR-29a-3p and miR-34a-5p in neurotoxin MPP treated SH-SY5Y cells. Our findings revealed that while co-treatment of the cells with 7-BIO and MPP did not alter the toxicity induced by MPP, pretreatment with 3.5 μM 7-BIO for 6 h increased the survival of the 2 mM MPP treated cells. Also, qRT-PCR analysis of gene expression showed that while miR-29a-3p was unchanged in cells treated with either 2 mM MPP or 3.5 μM 7-BIO alone, miR-34a-5p was increased by MPP but decreased by 7-BIO. Pretreatment with 3.5 μM 7-BIO prior to MPP however, increased miR-29a-3p but decreased miR-34a-5p induced by MPP. We therefore suggest that 7-BIO inhibition of GSK3β alleviates the MPP induced neurotoxicity by regulating miR-29a-3p and miR-34a-5p expressions in Parkinson's disease model SH-SY5Y cells.
