OBJECTIVE

To observe the effect of ginkgo biloba extract on myocardial apoptosis after myocardial infarction and its influence on the expression of signaling pathway proteins by regulating the Wnt/β-catenin signaling pathway.

METHODS

Thirty-five SD rats were selected as the experimental subjects and divided into the blank control group, the model group, the captopril group, and the low-dose and high-dose groups of ginkgo biloba extract. After 24 hours of modeling, continuous intervention was performed for 6 weeks. Cardiac function indicators of rats were detected, and pathological changes of rat myocardial tissue were observed. Enzyme-linked immunosorbent assay (ELISA) was used to detect serum CK-MB, cTnT levels, and collagen Ⅰ and collagen Ⅲ levels in myocardial tissue. Western blot (WB) was used to detect the protein expression levels of β-catenin, Wnt5a, and cleaved caspase-3 in rat myocardial tissue. Reverse transcription quantitative polymerase chain reaction (RT-qPCR) was used to detect the mRNA expression levels of β-catenin and MMP-9.

RESULTS

Compared with the blank control group, the levels of LVESD and LVEDD in the model group rats were increased, while the levels of LVEF and LVFS were decreased. The expression levels of serum CK-MB, cTnT, and collagen I and collagen III in myocardial tissue were increased. The mRNA expression of β-catenin and MMP-9 mRNA in myocardial tissue was increased. and the protein expression of β-catenin, Wnt5a, and cleaved-caspase-3 proteins was also increased. Compared with the model group, the treatment groups showed decreased levels of LVESD and LVEDD, and increased levels of LVEF and LVFS. The serum indicators and collagen content of rats in each treatment group were reduced. The expression of β-catenin and MMP-9 mRNA in myocardial tissue was reduced. And the expression of β-catenin, Wnt5a, and cleaved-caspase-3 proteins were significantly reduced. Compared with the captopril group, the low-dose ginkgo biloba extract group showed improved cardiac function indicators, and the high-dose group exhibited more significant improvement than the low-dose group. The serum indicators and collagen content in both low-dose and high-dose ginkgo biloba extract groups were decreased. The mRNA expression was decreased in the low-dose group, while there was no statistically significant difference in the high-dose group cmRNA expression in the high-dose group. The protein expression levels in both low-dose and high-dose groups were increased compared with the captopril group.

CONCLUSION

Ginkgo biloba extract improves myocardial injury in rats with myocardial infarction by inhibiting the Wnt/β-catenin signaling pathway, improving cardiac function related indicators, reducing the degree of myocardial injury, and ultimately improving rat cardiac function.

目的

观察银杏叶提取物通过调节Wnt/β-连环蛋白信号通路影响心肌梗死后心肌凋亡及对信号通路蛋白表达的影响。

方法

选用35只SD大鼠作为实验对象,分为空白对照组、模型组、卡托普利组和银杏叶提取物低、高剂量组;造模24 h后,连续干预6周。检测大鼠心功能指标;观察组织病理学变化;ELISA法检测大鼠CK-MB、cTnT、CollagenⅠ、CollagenⅢ水平;WB检测大鼠β-连环蛋白(β-catenin)、Wnt5a、裂解型半胱天冬酶-3(cleaved-caspase-3)蛋白表达水平;RT-qPCR检测β-catenin、MMP-9 mRNA表达。

结果

与空白对照组比,模型组大鼠LVESD、LVEDD水平升高,LVEF、LVFS水平降低;血清CK-MB、cTnT及心肌组织CollagenⅠ、CollagenⅢ含量表达升高;心肌组织MMP-9、β-cateninmRNA表达升高;且β-catenin、Wnt5a、cleaved-caspase-3蛋白表达均升高。与模型组比较,给药组LVESD、LVEDD水平升高,LVEF、LVFS水平降低;给药组大鼠血清指标和胶原蛋白含量降低;心肌组织β-catenin、MMP-9mRNA表达降低;且β-catenin、Wnt5a、cleaved-caspase-3蛋白表达均降低。与卡托普利组相比,低剂量组的心功能指标改善,且与低剂量组相比,高剂量组的心功能指标改善;银杏叶提取物高、低剂量组的血清指标和胶原蛋白含量升高;低剂量组的mRNA表达升高,高剂量组的mRNA表达无统计学差异;且低、高剂量组蛋白表达均有所增多。

结论

银杏叶提取物通过抑制Wnt/β-catenin信号通路,改善心肌梗死大鼠心肌损伤,改善心功能相关指标,降低心肌损伤程度,进而改善大鼠心脏功能。

目的

观察银杏叶提取物通过调节Wnt/β-连环蛋白信号通路影响心肌梗死后心肌凋亡及对信号通路蛋白表达的影响。

方法

选用35只SD大鼠作为实验对象,分为空白对照组、模型组、卡托普利组和银杏叶提取物低、高剂量组;造模24 h后,连续干预6周。检测大鼠心功能指标;观察组织病理学变化;ELISA法检测大鼠CK-MB、cTnT、CollagenⅠ、CollagenⅢ水平;WB检测大鼠β-连环蛋白(β-catenin)、Wnt5a、裂解型半胱天冬酶-3(cleaved-caspase-3)蛋白表达水平;RT-qPCR检测β-catenin、MMP-9 mRNA表达。

结果

与空白对照组比,模型组大鼠LVESD、LVEDD水平升高,LVEF、LVFS水平降低;血清CK-MB、cTnT及心肌组织CollagenⅠ、CollagenⅢ含量表达升高;心肌组织MMP-9、β-cateninmRNA表达升高;且β-catenin、Wnt5a、cleaved-caspase-3蛋白表达均升高。与模型组比较,给药组LVESD、LVEDD水平升高,LVEF、LVFS水平降低;给药组大鼠血清指标和胶原蛋白含量降低;心肌组织β-catenin、MMP-9mRNA表达降低;且β-catenin、Wnt5a、cleaved-caspase-3蛋白表达均降低。与卡托普利组相比,低剂量组的心功能指标改善,且与低剂量组相比,高剂量组的心功能指标改善;银杏叶提取物高、低剂量组的血清指标和胶原蛋白含量升高;低剂量组的mRNA表达升高,高剂量组的mRNA表达无统计学差异;且低、高剂量组蛋白表达均有所增多。

结论

银杏叶提取物通过抑制Wnt/β-catenin信号通路,改善心肌梗死大鼠心肌损伤,改善心功能相关指标,降低心肌损伤程度,进而改善大鼠心脏功能。

OBJECTIVE

To observe the effect of ginkgo biloba extract on myocardial apoptosis after myocardial infarction and its influence on the expression of signaling pathway proteins by regulating the Wnt/β-catenin signaling pathway.

METHODS

Thirty-five SD rats were selected as the experimental subjects and divided into the blank control group, the model group, the captopril group, and the low-dose and high-dose groups of ginkgo biloba extract. After 24 hours of modeling, continuous intervention was performed for 6 weeks. Cardiac function indicators of rats were detected, and pathological changes of rat myocardial tissue were observed. Enzyme-linked immunosorbent assay (ELISA) was used to detect serum CK-MB, cTnT levels, and collagen Ⅰ and collagen Ⅲ levels in myocardial tissue. Western blot (WB) was used to detect the protein expression levels of β-catenin, Wnt5a, and cleaved caspase-3 in rat myocardial tissue. Reverse transcription quantitative polymerase chain reaction (RT-qPCR) was used to detect the mRNA expression levels of β-catenin and MMP-9.

RESULTS

Compared with the blank control group, the levels of LVESD and LVEDD in the model group rats were increased, while the levels of LVEF and LVFS were decreased. The expression levels of serum CK-MB, cTnT, and collagen I and collagen III in myocardial tissue were increased. The mRNA expression of β-catenin and MMP-9 mRNA in myocardial tissue was increased. and the protein expression of β-catenin, Wnt5a, and cleaved-caspase-3 proteins was also increased. Compared with the model group, the treatment groups showed decreased levels of LVESD and LVEDD, and increased levels of LVEF and LVFS. The serum indicators and collagen content of rats in each treatment group were reduced. The expression of β-catenin and MMP-9 mRNA in myocardial tissue was reduced. And the expression of β-catenin, Wnt5a, and cleaved-caspase-3 proteins were significantly reduced. Compared with the captopril group, the low-dose ginkgo biloba extract group showed improved cardiac function indicators, and the high-dose group exhibited more significant improvement than the low-dose group. The serum indicators and collagen content in both low-dose and high-dose ginkgo biloba extract groups were decreased. The mRNA expression was decreased in the low-dose group, while there was no statistically significant difference in the high-dose group cmRNA expression in the high-dose group. The protein expression levels in both low-dose and high-dose groups were increased compared with the captopril group.

CONCLUSION

Ginkgo biloba extract improves myocardial injury in rats with myocardial infarction by inhibiting the Wnt/β-catenin signaling pathway, improving cardiac function related indicators, reducing the degree of myocardial injury, and ultimately improving rat cardiac function.
