Abstract

Several observations, both in humans and laboratory animals, have suggested that proanthocyanidins exhibit a broad spectrum of pharmacological, therapeutic and chemoprotective properties. Specifically, some of our earlier studies have shown that IH636 grape seed proanthocyanidin extract (GSPE, commercially known as ActiVin) provides excellent concentration- and dose-dependent protection against toxicities induced by diverse agents, such as acetaminophen, hydrogen peroxide, 12-O-tetradecanoylphorbol-13-acetate (TPA), smokeless-tobacco extract, idarubicin and 4-hydroxyperoxycyclophosphamide in both in vitro and in vivo models. In some models, GSPE proved to be a better cytoprotectant than vitamins C, E and beta-carotene. The purpose of this investigation was three fold: (i) to indirectly assess the bioavailability of GSPE in multiple target organs, (ii) quantify GSPE's capacity to avert cadmium chloride (CdCl2)-induced nephrotoxicity, dimethylnitrosamine (DMN)-induced splenotoxicity and O-ethyl-S,S-dipropyl phosphorodithioate (MOCAP)-induced neurotoxicity, and lastly (iii) to evaluate possible mechanisms of protection in mice. In order to determine all these, three separate experiments were designed and each experiment consisted ...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
