Abstract

Plant steroids are being recognized as influential secondary bio factors, assimilating in animal tissues through diet and affecting their cellular metabolic function to varying degree. They modulate catalytic and signaling functions in mammalian cells, affecting cellular homeostasis. The effect of phyto brassinosteroid ketoisoform 28-homocastasterone (28-HC), was assessed for its influence on blood glucose, plasma lipid and selective signal marker levels in normal and diabetic male wistar rat models. A 15 day oral feed regimen employing the experimental rat, noted that circulating blood glucose, cholesterol and triglyceride level in diabetic rat were markedly reduced by this compound. This study confirmed that the keto form had anti-hyperglycemic and anti-lipidemic potency associated with it and was available to man and animals in their diet. Western blots of marker protein, PCR amplicons of marker mRNA expressions and In Silico studies suggested that 28-HCeffect is being mediated through LxR molecular operatives in the rat cell.
