ClC-3氯通道过表达对小鼠甲状腺结构及功能的影响

         

摘要

目的:研究过表达ClC-3基因对小鼠甲状腺结构及功能的影响.方法:以3月龄FVB小鼠为实验对象,研究野生型(WT)小鼠和ClC-3转基因小鼠甲状腺结构及功能的差异.用qPCR、Westren blot和免疫荧光技术观察小鼠甲状腺ClC-3的表达与分布;对小鼠日常活动进行行为学监测;ELISA检测小鼠血清总三碘甲状腺原氨酸(TT3)、总甲状腺素(TT4)和促甲状腺激素(TSH)的浓度.结果:与WT组小鼠相比:ClC-3转基因组小鼠甲状腺ClC-3表达明显增多(P<0.05);甲状腺表现为明显的增生,滤泡明显增大;体重减轻但摄食量增加(P<0.05),毛发无光泽,行为活跃,易激惹;TT3、TT4明显增高(P<0.05),但TSH变化不明显.结论:ClC-3过表达可导致甲状腺组织增生,甲状腺激素分泌增多.本研究提示ClC-3很可能参与了甲状腺激素的合成.%AIM:To study the effect of ClC-3 gene over-expression on thyroid structure and function in mice. METHODS:Three-months-old FVB mice were used to study the difference of thyroid structure and function between wild-type(WT)mouse and ClC-3 transgene mice.The expression and distribution of ClC-3 in the thyroid of mice were deter-mined by the methods of qPCR,Western blot and immunofluorescence.Behavioral monitoring was performed on the daily activities of mice.Serum concentrations of total triiodothyronine(TT3), total thyroxine(TT4)and thyrotropin(TSH) were measured by ELISA.RESULTS:Compared with the WT group,the expression of ClC-3 in the thyroid of ClC-3 trans-gene group was significantly increased(P<0.05).The thyroid gland showed obvious hyperplasia and the folliculi glandu-lae thyreoideae was significantly bigger in ClC-3 transgene mice(P<0.05).The weight loss was increased in ClC-3 trans-gene mice(P<0.05).The expression of TT3 and TT4 were significantly higher than that of WT group(P<0.05),but the change of TSH was not obvious.CONCLUSION:ClC-3 over-expression results in thyroid hyperplasia and thyroid hor-mone secretion.This study suggests that ClC-3 is likely to be involved in the synthesis of thyroid hormones.
