28-HOMOCASTASTERONE: A NOVEL DIETARY PHYTO KETO OXYSTEROL MODULATING TESTICULAR STEROID METABOLISM AND LxR mRNA EXPRESSION IN DIABETIC RAT

Abstract

Objective: Present study aims to investigate 28-homocastasterone (28-HC) influences on testicular tissue in the normal and diabetic rat.Methods: Induction of diabetes was achieved by single peritoneal injection of streptozotocin (60 mg/kg b. wt) followed by 28-HC (100 µg/150 gm body weight) administration by oral gavage for 15 consecutive days to experimental rats. 3β-hydroxysteroid dehydrogenase, 17β-hydroxysteroid dehydrogenase activities, testosterone level, Liver X Receptor (LxR) mRNA expression, malondialdehyde (MDA), reduced glutathione (GSH) and testis histology was analysed.Results: Increased cholesterol level, 3β-hydroxysteroid dehydrogenase (3βHSD), 17β-hydroxysteroid dehydrogenase (17βHSD) activities, testosterone level with significant elevation of LxR-α and β mRNA expression in treated rat testis. A significant reduction found inMDA and increased reducedGSH along with improved testicular architecture was observed.Conclusion: In the present study demonstrated that 28-HC induced 3βHSD, 17βHSD enzyme activity and testosterone level, thus indicative of steroidogenic potential and capable of transactivating LxR-α and β molecular operative in rat testicular tissue.

Therapeutic Potential of Brassinosteroids in Biomedical and Clinical Research

“…It was found that brassinosteroid keto isoform homocastasterone exhibited antiglycemic activity in diabetic rats and also improved RBC, WBC, platelets, hemoglobin levels, and reduced cell damage and inflammatory disorders such as inflammatory bowel disease, allergic reactions, and leukemia or myeloproliferative neoplasms in humans [131].…”
