Background: Medicinal plants have been known as one of the most important therapeutic agents for cancer treatment and prevention. Capparis spinosa L is a multipurpose plant that contains different bioactive phytochemicals including phenols and flavonoids.Aims: In the present study we explore the invivo antitumor activity of Capparis spinosa L extract and most potent constituents rutin and hesperidin against Ehrlich ascites carcinoma (EAC). Also study the side effect of treatments on different organs (liver, kidney and heart). Material and method: The antitumor effect was assessed by evaluating tumor volume , tumor cell count , survival time and increase in life span of EAC bearing mice. We assessed the effect of Capparis spinosa L extract , rutin and hesperidin on the level of malonaldialdhyde (MDA) and Catalase activity. Also, we estimated their effect on Alanine aminotransferase (ALT), Aspartate aminotransferase (AST) , Albumin , urea , creatinine ,Lactate dehydrogenase activity (LDH), Creatine Kinase-MB activity (CK-MB). Apoptosis was assessed by BCL2 and caspase3 activity. Results : The Capparis spinosa L extract , rutin and hesperidin showed significantly decreased (p<0.001) in the volume of the EAC and in the count of EAC cells and increase the life span of EAC bearing mice. The treatment with Capparis spinosa L extract , rutin and hesperidin showed significantly decreased (p<0.001) the lipid peroxidation marker (MDA) and recovered catalase activity towards normal as compared to positive control. We founded that Capparis spinosa L extract , rutin and hesperidin treatment induced apoptosis demonstrated by an increased in Caspase 3 activity and decreased in BCL2 .The treatment of Capparis spinosa L extract , rutin and hesperidin significantly reduced the elevated levels of ALT , AST ,LDH ,CK-MB,Urea and Creatinine in positive control as compared with negative control. Also, they showed protection for both liver and kidney histopathologically. Conclusions: The present study demonstrated that Capparis spinosa L extract , rutin and hesperidin have potent antitumor activity against Ehrlich ascites carcinoma. The anti-tumor mechanism may be mediated by preventing oxidative damage and induction of apoptosis.

Background: Increasing evidence in both experimental and clinical studies suggests that there is a close link between hyperglycemia, oxidative stress, and diabetic complications. Resveratrol a polyphenolic compound found in various natural food products. Aim: The aim of the present study was to screen insulin sensitization via PPARγ and glucose uptake through activation of PI3K/p-Akt signaling pathway by resveratrol in type 2 diabetic rats Material and methods: Four groups male adult albino rats were used in this study: Negative control, Positive control, Therapeutic group and Standard group. Results: The treatment of resveratrol significantly reduced the elevated levels of blood glucose, Total cholesterol, Triglyceride, LDL-c, Urea and Creatinine in positive control as compared with negative control. Treatment of resveratrol also reverted back the decreased levels of insulin, HDL-c, Irisin, enzymatic antioxidant (catalase and superoxide dismutase) as well as decreased level of the non-enzymatic antioxidant (reduced glutathione) in tissue extracts from different organs of diabetic rats to near normal values. Resveratrol significantly increased expression of the PPAR γ gene in adipose tissue compared to positive control. It also regulated insulin mediated glucose uptake in adipose tissue through activation of PI3K/p-Akt signaling pathway. PPARγ gene showed many different expressions for other side the PPARγ sequences from the adipose tissue confirm there is a mutation with the gene isolated from positive control against therapeutic group, meaning the Type 2 diabetes cause a mutation in the gene sequencing compared to negative control. Hence, we find the opposite with the PPARγ sequencing in therapeutic group. Conclusion: These results clearly suggest that the resveratrol has an antioxidant effects and could improve adipose tissue insulin sensitivity and maintain glucose homeostasis in adipose tissue.
