新生SD乳鼠心脏中分离原代心肌细胞,将其分为对照组、AngⅡ组(2 µmol/L)、TSG组(7.5 µg/mL)、PFK-015组[6-磷酸果糖-2-激
酶/果糖-2,6-二磷酸酶 3(PFKFB3)抑制剂 10 nmol/L]和 TSG+PFK-015 组(TSG 7.5 µg/mL+PFK-015 10 nmol/L),检测各组细胞表
面积、蛋白合成情况、能量代谢相关指标[游离脂肪酸(FFA)、辅酶A(CoA)、乙酰辅酶A(acetyl-CoA)]含量、糖酵解相关因子[缺氧
诱导因子1α(HIF-1α)、葡萄糖转运蛋白4(GLUT-4)、乳酸脱氢酶A(LDHA)、丙酮酸脱氢酶激酶1(PDK1)、PFKFB3]的表达情况。
结果 与对照组相比,AngⅡ组细胞表面积显著增大,蛋白合成显著增多,FFA 含量和 HIF-1α、LDHA、PDK1、PFKFB3 蛋白及
mRNA的表达均显著升高或上调,CoA、acetyl-CoA含量和GLUT-4蛋白及mRNA的表达均显著降低或下调(P<0.05)。与AngⅡ
组相比,TSG组和PFK-015组细胞上述指标均显著改善,且TSG+PFK-015组细胞的改善程度普遍优于TSG组和PFK-015组(P<

ABSTRACT OBJECTIVE To investigate the ameliorative effects and potential mechanism of total secondary ginsenosides
(TSG) on hypertrophic changes of primary cardiomyocytes stimulated by angiotensin Ⅱ (Ang Ⅱ ). METHODS Primary
cardiomyocytes were isolated from the hearts of neonatal SD rats and divided into the following groups: control group, AngⅡ
group (2 µmol/L), TSG group (7.5 µg/mL), PFK-015 group [6-phosphofructo-2-kinase/fructose-2, 6-bisphosphatase 3 (PFKFB3)
inhibitor, 10 nmol/L], and TSG+PFK-015 group (TSG 7.5 µg/mL+PFK-015 10 nmol/L). The surface area, protein synthesis,
energy metabolism-related indicators [free fatty acid (FFA), coenzyme A (CoA), acetyl coenzyme A (acetyl-CoA)], and the
expressions of glycolysis-related factors [hypoxia-inducible factor 1α (HIF-1α), glucose transporter protein 4 (GLUT-4), lactate
dehydrogenase A (LDHA), pyruvate dehydrogenase kinase 1 (PDK1) and PFKFB3] in primary cardiomyocytes of each group were
measured. RESULTS Compared with the control group, the surface area of primary cardiomyocytes and protein synthesis were
significantly increased, the content of FFA, protein and mRNA expressions of HIF-1α, LDHA, PDK1 and PFKFB3 were
significantly increased or up-regulated in the AngⅡ group, while the contents of CoA and acetyl-CoA, the protein and mRNA
expressions of GLUT-4 were significantly decreased or down-regulated (P<0.05). Compared with the AngⅡ group, both TSG
group and PFK-015 group showed significant improvements in these indexes, with the TSG+PFK-015 group generally
demonstrating superior effects compared to either treatment alone (P<0.05). CONCLUSIONS TSG can reduce the surface area of
AngⅡ-induced primary cardiomyocytes, decrease protein synthesis, and inhibit their hypertrophic changes. These effects may be
related to improving energy metabolism and the inhibition of glycolysis activity.
