摘要:
目的 探讨氯化锂对缺氧后神经干细胞磷酸化Caspase-9(P-Caspase-9)蛋白表达的影响。方法 分离培养新生Sprague-Dawley乳鼠神经干细胞(NSCs),建立缺氧NSCs模型。将NSCs分为正常对照组、单纯缺氧组、生理盐水干预组和1、3、5 mmol·L-1氯化锂干预组。正常对照组乳鼠NSCs加无血清培养基,单纯缺氧组乳鼠NSCs仅缺氧 1 h,生理盐水干预组乳鼠NSCs缺氧1 h后加生理盐水,3组氯化锂干预组乳鼠NSCs缺氧1 h后分别加入氯化锂至1、3、5 mmol·L-1。免疫组织化学法检测各组乳鼠NSCs中P-Caspase-9阳性细胞表达。结果 成功建立了NSCs缺氧模型。正常对照组、单纯缺氧组、生理盐水干预组及1、3、5 mmol·L-1氯化锂干预组P-Caspase-9阳性细胞数分别为126.400±0.548、21.000±0.707、21.200±0.837、64.600±0.548、116.800±1.483、17.200±1.643。单纯缺氧组和生理盐水干预组乳鼠NSCs中P-Caspase-9阳性细胞数比较差异无统计学意义(P>0.05);其余各组NSCs中P-Caspase-9阳性细胞数两两比较差异均有统计学意义(P<0.05)。结论 氯化锂可能通过磷脂酰肌醇-3-激酶/蛋白激酶B/Caspase-9信号通路调控缺氧NSCs增殖。
Abstract:
Objective To investigate the effect of lithium chloride on the expression of phospho-Caspase-9(P-Caspase-9) protein of hypoxic neural stem cell(NSCs).Methods The NSCs of neonatal Sprague-Dawley rats were isolated and cultured,and the hypoxic NSCs model was established.The NSCs were divided into normal control group,hypoxia group,physiological saline intervention group,and 1,3,5 mmol·L-1 lithium chloride intervention group.The NSCs of normal control group were cultured in serum-free medium;the NSCs of hypoxia group underwent hypoxia for 1 h;the NSCs of physiological saline intervention group were given normal saline after 1 h hypoxia;the NSCs of 1,3,5 mmol·L-1 lithium chloride intervention group were given 1,3,5 mmol·L-1 lithium chloride respectively after 1 h hypoxia.The expression of P-Caspase-9 in NSCs was detected by immunohistochemistry.Results The model of hypoxic NSCs was established successfully.The number of P-Caspase-9 positive cells in normal control group,hypoxia group,physiological saline intervention group,and 1,3,5 mmol·L-1 lithium chloride intervention group was 126.400±0.548,21.000±0.707,21.200±0.837,64.600±0.548,116.800±1.483,17.200±1.643 respectively.There was no statistic difference in the number of P-Caspase-9 positive cells between the hypoxia group and physiological saline intervention group(P>0.05);there was statistic difference in the number of P-Caspase-9 positive cells among another groups(P<0.05).Conclusion Lithium chloride may regulate the proliferation of hypoxic NSCs through phosphoinositide 3-kinase/ protein kinase B/Caspase-9 signaling pathway.
