               [摘   要] 目的:研究甲状腺激素合成和代谢相关基因表达与内脏脂肪米色化的关系。方法:收集甲状腺功能正常的正常体
                重和肥胖者的内脏脂肪组织,荧光实时定量PCR检测甲状腺激素合成和代谢相关基因、内脏脂肪米色化功能蛋白和转录因子
                的 mRNA 表达,并进行相关性分析。结果:肥胖者内脏脂肪组织甲状腺激素转运体包括溶质载体家族 16 成员 2 和成员 10
               (SLC16A2、SLC16A10)、溶质载体有机阴离子转运体家族成员 1C1(SLCO1C1)、促甲状腺激素β亚基(TSHB)和脱碘酶 2(iodo⁃
                thyronine deiodinase 2,DIO2)的mRNA表达均下降,其中SLC16A2、TSHB和DIO2差异有统计学意义。在校正年龄、性别、体重
                指数和FT3后内脏脂肪米色化功能蛋白UCP1及标志转录因子PR结构域家族成员16(PR domain⁃containing 16,PRDM16)的表
                达与上述基因表达呈正相关。结论:肥胖者内脏脂肪米色化功能下降与甲状腺激素合成和代谢密切相关。

               [Abstract] Objective:This study aims to study the relationship between thyroid hormone synthesis and metabolism⁃related gene
                expression and browning of visceral fat. Methods:The visceral fat tissues of normal weight and obese persons with normal thyroid
                function were collected,and the mRNA expression of genes related to thyroid hormone synthesis and metabolism,visceral fat beige
                functional protein and transcription factors were detected by fluorescence real⁃time quantitative PCR,then the correlation analysis was
                performed. Results:The mRNA expression of thyroid hormone transporters included solute carrier family 16 members 2 and 10
               (SLC16A2,SLC16A10),solute carrier organic anion transporter family member 1C1(SLCO1C1)thyroid stimulating hormone β
                subunit(TSHB)and iodothyronine deiodinase 2(DIO2)decreased significantly in the visceral adipose tissue of obese people. There
                were significant differences in SLC16A2,TSHB and DIO2 between two groups The expression of visceral fat beige functional protein
                UCP1 and marker transcription factor PR domain⁃containing 16(PR domain⁃containing 16,PRDM16)are positively correlated with the
                expression of the above genes after adjusted by age,gender,body mass indexand FT3. Conclusion:Decreased beige function of
                visceral fat in obese people is closely related to thyroid hormone synthesis and metabolism.
