Objective: To evaluate the effects of berberine (BBR) on the liver phosphatidate phosphohydrolase (PAP) and plasma lipids in rats fed on high lipogenic and normal diet.Methods:diet. Group II received standard diet plus 90 mg/kg BBR and Groups IV received lipogenic diet (containing sunflower oil, cholesterol and ethanol) without treatment. Groups III and V received lipogenic diet plus 90 mg/kg BBR and 30 mg/kg gemfibrozil, respectively. On Day 60 of the experiment, blood samples were collected and PAP, total cholesterol, triglyceride, low density lipoprotein cholesterol, high density lipoprotein cholesterol, very low density lipoprotein, malondialdehyde, plasma antioxidant, and liver histopathology assessments were conducted.Results:Forty rats were randomly divided into 5 groups. Group I (control) received standard malondialdehyde levels decreased significantly (P<0.05) in Group III compared to Group IV (24.94%, 36.11%, 21.18%, 36.86% and 19.59%, respectively). The liver triglyceride and cholesterol in Groups III and V had a remarkable decrease (P<0.001) compared with Group IV (24.94% and 49.13%, respectively). There was a significant reduction (P<0.05) in atherogenic index in Groups III compared with Group IV. PAP, plasma triglyceride, total cholesterol, very low density lipoprotein, and Conclusions: These results clearly suggested that BBR could be effective in reducing liver PAP, lipid abnormality, liver triglyceride and lateral side effects of hyperlipidemia.

Background: In this study, we demonstrated the effects of the Gallic Acid (GA) molecule on the prostate cancer cells line PC3 using the comet assay (Alkaline electrophoresis) technique and its effects on some important apoptotic factors including BAD (Bcl-2-Associated Death promoter), BAK (Bcl-2 homologous Antagonist/Killer), and BIM (Bcl-2-like protein 11) via simulation analysis by using the Auto Dock and Gromacs software. Methods: Following the MTT assay on the PC3 cells, and determining IC50, we used three concentrations of GA to around IC50 to treat PC3 cells. 100 comet pictures were obtained by alkaline electrophoresis and have been analysed with the CASP version 1.2.2 software; all the results were thereafter analysed by the SPSS version 21 statistical software. Results: The IC50 value for GA was determined to be 35 μM. The ratio of tail to head in alkaline electrophoresis for the three concentrations below the IC50 of GA in 25, 30, and 35 μM were measured as 24.7 (2.7), 44.5 (1.8), and 57.3 (1.3) percent, respectively. The results of the preapoptotic factors (BAD, BAK, and BIM) in the performed simulation in the absence and presence of GA showed that the GA protein causes the structural instability in the BAD protein, and the effect of GA can be explained by the creation of hydrogen bonds with proteins. Conclusion: GA is a polyphenol compound in plants that can suppress cell growth and induce apoptosis in PC3 cells in prostate cancer in the range of IC50 concentrations. The apoptotic properties of GA induce pre-apoptotic factors.
