Effect of nicotine against apoptosis of rat cortical neurons induced by colchicines / 中国病理生理杂志

ABSTRACT

AIM: To explore the mechanism of nicotine against the apoptosis induced by colchicines in rat cortical neurons.METHODS: Cortical neurons were cultured from newborn Sprague-Dawley(SD) rats(less than 12 h).The rate of apoptosis was measured by Hoechst33258 fluorescence staining in the neurons,and the activity of Akt473 was analyzed by assay kit Akt473.RESULTS: The apoptosis of cortical neurons can be induced by 0.1 ?mol/L colchicine.The phosphorlation of Akt 473 decreased significantly(1/3 times of the control group,P
