Metabolic syndrome (MetS) is a group of risk factors in the form of central obesity, insulin resistance, dyslipidemia, and hypertension, increasing oxidative stress. This pathological event leads to the development of cardiovascular disease, for instance, atherosclerosis. Besides modifiable risk factors, non-modifiable risk factors such as genetic factors also play a role in the formation of atherosclerosis in MetS conditions such as THOC5, AIF1, CNN1, and ACTA2. Recently, natural compound derivatives, such as epigallocatechin-3-gallate (EGCG), chlorogenic acid (CGA), and turmeric, have shown beneficial effects in MetS improvement. This study aimed to investigate the effect of green tea, green coffee, and turmeric extract on the expression of THOC5, AIF1, CNN1, and ACTA2 genes that contributed to atherosclerotic vasculopathy development in the MetS rat model. Twenty-five MetS rat models were grouped into 4 groups (n = 5): Standard control (SC), MetS (MetS), a combination of green tea, green coffee, and turmeric extract with treatment doses: 300/100/150 mg/BW(C1) and 400/200/250 mg/BW(C2) group. The THOC5, AIF1, CNN1, and ACTA2 expression were measured at the end of treatment periods. This study found that administering green tea, green coffee, and turmeric extract can lower the expression of THOC5, AIF1, CNN1, and ACTA2. The correlation test showed that there is a strong correlation between THOC5 and AIF1 gene expression, with positive value. In summary, the combined effects of green tea, green coffee, and curcumin extract show significant promise as a potential anti-atherosclerosis treatment by improve the THOC5 and AIF1, but not ACTA2 and CNN1 gene expression in the aortic tissue of metabolic syndrome model.
