Objective

To explore the molecular mechanism of berberine in improving insulin resistance and liver lipid metabolism in obesity mice.

Methods

Sixty clean-grade C57BL/6 mice were randomly divided into control group (normal diet), model group (high fat diet), experimental-L group (model+50.00 mg·kg-1 berberine), experimental-H group (model+100.00 mg·kg-1 berberine), inhibitor NC group (model +100.00 mg·kg-1 berberine + tail vein injection mmu-inhibitor NC), miR-125a inhibitor group (model +100.00 mg·kg-1 berberine + tail vein injection of mmu-miR-125a inhibitor). Berberine was administered by gavage once a day, and subcutaneous injection was performed every 4 days. After a continuous treatment period of 28 days, the insulin resistance levels were detected, serum lipid levels were analyzed, the expression levels of related genes were detected by real-time quantitative polymerase chain reaction (RT-qPCR), and the expression of related proteins in liver tissue was detected by Western blot (WB).

Results

The levels homeostatis model assessment of insulin resistance (HOMA-IR) in control group, model group, experimental-H group, inhibitor NC group and miR-125a inhibitor group were 2.56±0.11, 7.23±0.67, 5.04±0.20, 4.99±0.34 and 6.46±0.40, respectively; triglyceride (TG) levels were (0.46±0.04), (0.93±0.08), (0.65±0.05), (0.63±0.06) and (0.74±0.06) mmol·L-1, respectively; the relative expression levels of miR-125a were 1.00±0.12, 0.56±0.07, 0.77±0.10, 0.78±0.11 and 0.21±0.03, respectively; fatty acid synthase (FAS) mRNA were 1.00±0.10, 1.90±0.14, 1.40±0.22, 1.41±0.16 and 1.67±0.14, respectively; the relative protein expression levels of phosphorylated phosphatidylase 3-kinase (p-PI3K) were 0.78±0.09, 0.42±0.05, 0.69±0.06, 0.70±0.03 and 0.51±0.06, respectively; phosphorylated protein kinase B (p-AKT) protein levels were 0.84±0.12, 0.30±0.05, 0.64±0.08, 0.65±0.08 and 0.49±0.07, respectively. Compared between the model group and the control group; between the experimental-H group and the model group; and between the miR-125a inhibitor group and the inhibitor NC group, all differences of the above inclicatovs went statistically significant (P<0.01, P<001).

Conclusion

Berberine may improve insulin resistance and fat metabolism in obesity mice by activating PI3K/AKT signal through miR-125a.

目的

探讨小檗碱改善肥胖小鼠胰岛素抵抗和肝脂质代谢的分子机制。

方法

将60只清洁级C57BL/6小鼠随机分为对照组(普通饲料)、模型组(高脂饲料)、低剂量实验组(模型+50.00 mg·kg-1的小檗碱)、高剂量实验组(模型+100.00 mg·kg-1的小檗碱)、inhibitor NC组(模型+100.00 mg·kg-1的小檗碱+尾静脉注射mmu-inhibitor NC),miR-125a inhibitor组(模型+100.00 mg·kg-1的小檗碱+尾静脉注射mmu-miR-125a inhibitor),小檗碱一天灌胃1次,皮下注射每隔4 d 1次,连续治疗28 d后检测胰岛素抵抗水平、用全自动生化分析血清血脂指标水平,实时定量聚合酶链式反应(RT-qPCR)实验检测相关基因表达水平,蛋白质印迹(WB)实验检测肝组织相关蛋白表达。

结果

对照组、模型组、高剂量实验组、inhibitor NC组和miR-125a inhibitor组胰岛素抵抗水平(HOMA-IR)分别为2.56±0.11、7.23±0.67、5.04±0.20、4.99±0.34及6.46±0.40;甘油三酯(TG)水平分别为(0.46±0.04)、(0.93±0.08)、(0.65±0.05)、(0.63±0.06)及(0.74±0.06)mmol·L-1miR-125a相对表达水平分别为1.00±0.12、0.56±0.07、0.77±0.10、0.78±0.11及0.21±0.03;脂肪酸合成酶(FAS)mRNA水平分别为1.00±0.10、1.90±0.14、1.40±0.22、1.41±0.16及1.67±0.14;磷酸化-磷脂酰化醇3-激酶(p-PI3K)蛋白水平分别为0.78±0.09、0.42±0.05、0.69±0.06、0.70±0.03及0.51±0.06;磷酸化-蛋白质激酶B(p-AKT)蛋白水平分别为0.84±0.12、0.30±0.05、0.64±0.08、0.65±0.08及0.49±0.07;模型组上述指标与对照组比较,高剂量实验组上述指标与模型组比较,miR-125a inhibitor组上述指标与inhibitor NC组比较,在统计学上差异均具有统计学意义(P<0.01,P<001)。

目的

探讨小檗碱改善肥胖小鼠胰岛素抵抗和肝脂质代谢的分子机制。

方法

将60只清洁级C57BL/6小鼠随机分为对照组(普通饲料)、模型组(高脂饲料)、低剂量实验组(模型+50.00 mg·kg-1的小檗碱)、高剂量实验组(模型+100.00 mg·kg-1的小檗碱)、inhibitor NC组(模型+100.00 mg·kg-1的小檗碱+尾静脉注射mmu-inhibitor NC),miR-125a inhibitor组(模型+100.00 mg·kg-1的小檗碱+尾静脉注射mmu-miR-125a inhibitor),小檗碱一天灌胃1次,皮下注射每隔4 d 1次,连续治疗28 d后检测胰岛素抵抗水平、用全自动生化分析血清血脂指标水平,实时定量聚合酶链式反应(RT-qPCR)实验检测相关基因表达水平,蛋白质印迹(WB)实验检测肝组织相关蛋白表达。

结果

对照组、模型组、高剂量实验组、inhibitor NC组和miR-125a inhibitor组胰岛素抵抗水平(HOMA-IR)分别为2.56±0.11、7.23±0.67、5.04±0.20、4.99±0.34及6.46±0.40;甘油三酯(TG)水平分别为(0.46±0.04)、(0.93±0.08)、(0.65±0.05)、(0.63±0.06)及(0.74±0.06)mmol·L-1miR-125a相对表达水平分别为1.00±0.12、0.56±0.07、0.77±0.10、0.78±0.11及0.21±0.03;脂肪酸合成酶(FAS)mRNA水平分别为1.00±0.10、1.90±0.14、1.40±0.22、1.41±0.16及1.67±0.14;磷酸化-磷脂酰化醇3-激酶(p-PI3K)蛋白水平分别为0.78±0.09、0.42±0.05、0.69±0.06、0.70±0.03及0.51±0.06;磷酸化-蛋白质激酶B(p-AKT)蛋白水平分别为0.84±0.12、0.30±0.05、0.64±0.08、0.65±0.08及0.49±0.07;模型组上述指标与对照组比较,高剂量实验组上述指标与模型组比较,miR-125a inhibitor组上述指标与inhibitor NC组比较,在统计学上差异均具有统计学意义(P<0.01,P<001)。

结论

小檗碱可能通过miR-125a激活PI3K/AKT信号改善肥胖小鼠胰岛素抵抗和肝脏脂质代谢。

Objective

To explore the molecular mechanism of berberine in improving insulin resistance and liver lipid metabolism in obesity mice.

Methods

Sixty clean-grade C57BL/6 mice were randomly divided into control group (normal diet), model group (high fat diet), experimental-L group (model+50.00 mg·kg-1 berberine), experimental-H group (model+100.00 mg·kg-1 berberine), inhibitor NC group (model +100.00 mg·kg-1 berberine + tail vein injection mmu-inhibitor NC), miR-125a inhibitor group (model +100.00 mg·kg-1 berberine + tail vein injection of mmu-miR-125a inhibitor). Berberine was administered by gavage once a day, and subcutaneous injection was performed every 4 days. After a continuous treatment period of 28 days, the insulin resistance levels were detected, serum lipid levels were analyzed, the expression levels of related genes were detected by real-time quantitative polymerase chain reaction (RT-qPCR), and the expression of related proteins in liver tissue was detected by Western blot (WB).

Results

The levels homeostatis model assessment of insulin resistance (HOMA-IR) in control group, model group, experimental-H group, inhibitor NC group and miR-125a inhibitor group were 2.56±0.11, 7.23±0.67, 5.04±0.20, 4.99±0.34 and 6.46±0.40, respectively; triglyceride (TG) levels were (0.46±0.04), (0.93±0.08), (0.65±0.05), (0.63±0.06) and (0.74±0.06) mmol·L-1, respectively; the relative expression levels of miR-125a were 1.00±0.12, 0.56±0.07, 0.77±0.10, 0.78±0.11 and 0.21±0.03, respectively; fatty acid synthase (FAS) mRNA were 1.00±0.10, 1.90±0.14, 1.40±0.22, 1.41±0.16 and 1.67±0.14, respectively; the relative protein expression levels of phosphorylated phosphatidylase 3-kinase (p-PI3K) were 0.78±0.09, 0.42±0.05, 0.69±0.06, 0.70±0.03 and 0.51±0.06, respectively; phosphorylated protein kinase B (p-AKT) protein levels were 0.84±0.12, 0.30±0.05, 0.64±0.08, 0.65±0.08 and 0.49±0.07, respectively. Compared between the model group and the control group; between the experimental-H group and the model group; and between the miR-125a inhibitor group and the inhibitor NC group, all differences of the above inclicatovs went statistically significant (P<0.01, P<001).

Conclusion

Berberine may improve insulin resistance and fat metabolism in obesity mice by activating PI3K/AKT signal through miR-125a.
