ABSTRACT

 

Zamani-Pereshkaft M, Mehrabani D, Borzou B, Zare S, Jamhiri I., Effects of Methamphetamine on KI-67, PPARα, PPARγ and Bax genes on human SH-SY5Y cell proliferation, differentiation and apoptosis, Onl J Vet Res., (10):684-694, 2021. Methamphetamine is a powerful stimulant of the central nervous system. We describe effect of the drug on cell viability, proliferation, differentiation and apoptosis in human SH-SY5Y cells. Succinate dehydrogenase activity (MTT assay) was used to determine neurotoxicity and RT-PCR for effects on expression of KI-67, PPARα, PPARγ and Bax genes in human SH-SY5Y cell proliferation, differentiation and apoptosis. Glyceraldehyde-3-phosphate dehydrogenase was used as housekeeping gene. SH-SY5Y cells appeared neuroblastic growing in clusters and clumps. Methamphetamine was associated with dose dependent reductions in SH-SY5Y cell viability Compared with SHSY-5Y controls, 1.2μM methamphetamine increased expression of Bax gene 1.51 fold (P < 0.01). In contrast Ki-67 gene declined 0.55 and 0.41 fold (p < 0.002-0.0004). Doses of 0.6 or 1.2um metamphetamine, reduced PPARα gene 0.75 and 0.54 fold (p < 0.02-0.002) and PPARγ expression 0.06 and 0.04 fold. We find that low dose 0.6-1.2 μM methamphetamine reduced human SH-SY5Y cell viability, proliferation and differentiation and enhanced apoptosis.

Key words: Methamphetamine, Neurotoxicity, SH-SY5Y cells, Proliferation, Differentiation, Apoptosis.
