Role of Vitamin E-acetate on Cisplatin induced genotoxicity: An in vivo analysis

Central European Journal of Biology (Impact Factor: 0.71). 04/2012; 7(2). DOI: 10.2478/s11535-012-0001-z

ABSTRACT Vitamin E has generated immense interest because of its potential of being an antioxidant, a neuroprotector, and a protector against
atherosclerosis, carcinogenesis and cardiovascular disease. However, the prooxidant chemistry of Vitamin E cannot be ignored since
it is related to the generation of peroxyl radicals. In the present study, 125, 250 and 500 mg/kg of Vitamin E-acetate (VE) administered
intraperitoneally (i.p.) to Balb/C mice significantly induced 6.00%, 8.00% and 11.33% (control value=2.33%) of chromosome
aberrations (CA) and 0.88%, 1.39% and 1.81% (control value=0.61%) of micronucleus (MN), following 24 hour of treatment in
the bone marrow cells. In the germ cells, VE did not induce any sperm head abnormality (SHA) after 35 days of exposure. Most
importantly, it has been observed that pre-treatment with VE significantly reduces CA, MN, and SHA induction by chemotherapeutic
drug Cisplatin (CIS). Our findings suggest that lone treatment with VE induce genotoxicity in somatic cells after 24 and 48 hours of
exposure but not in germ cells after 35 days of exposure, whereas pre-treatment with VE reduces CIS induced genotoxicity as well
as cytotoxicity. There exists a thin line of difference on the behavioral transition of VE when acting alone and when acting with a drug.

    ABSTRACT: To evaluate and synthesize the evidence on the effect of supplements of vitamin E on the prevention and treatment of cardiovascular disease. Systematic review of placebo-controlled randomized controlled trials; meta-analysis where justified. Eighty-four eligible trials were identified. For the outcomes of all-cause mortality, cardiovascular mortality, fatal or nonfatal myocardial infarction, and blood lipids, neither supplements of vitamin E alone nor vitamin E given with other agents yielded a statistically significant beneficial or adverse pooled relative risk (for example, pooled relative risk of vitamin E alone = 0.96 [95% confidence interval (CI), 0.84 to 1.10]; 0.97 [95% CI, 0.80 to 1.90]; and 0.72 [95% CI, 0.51 to 1.02] for all-cause mortality, cardiovascular mortality, and nonfatal myocardial infarction, respectively. There is good evidence that vitamin E supplementation does not beneficially or adversely affect cardiovascular outcomes.

    ABSTRACT: Natural vitamin E consists of four different tocopherol and four different tocotrienol homologues (alpha,beta, gamma, delta) that all have antioxidant activity. However, recent data indicate that the different vitamin E homologues also have biological activity unrelated to their antioxidant activity. In this review, we discuss the anti-inflammatory properties of the two major forms of vitamin E, alpha-tocopherol (alphaT) and gamma-tocopherol (gammaT), and discuss the potential molecular mechanisms involved in these effects. While both tocopherols exhibit anti-inflammatory activity in vitro and in vivo, supplementation with mixed (gammaT-enriched) tocopherols seems to be more potent than supplementation with alphaT alone. This may explain the mostly negative outcomes of the recent large-scale interventional chronic disease prevention trials with alphaT only and thus warrants further investigation.

    ABSTRACT: The purpose of this study was to measure and compare the effect of d-alpha-tocopheryl succinate (alpha-TS) in modifying radiation-induced chromosomal damage in human normal cells and cancer cells in culture. Three human normal fibroblast cell lines (GM2149, AG1522 and HF19) and three human cancer cell lines, cervical cancer (HeLa) and ovarian carcinoma cells (OVGI and SKOV3) were treated with alpha-TS (37.6 microM) 20 hours before 100 cGy gamma-irradiation. After 30 minutes of irradiation, colcemid was added and cells were fixed. One hundred randomly selected metaphase cells were scored for the presence of chromatid gaps and breaks. To study the cellular accumulation of alpha-TS. cells were incubated in the presence of alpha-TS (18.8 and 37.6 microM) for 24 hours, and alpha-TS was extracted with hexane using a-tocopheryl acetate as an internal standard. The levels of alpha-TS were determined by HPLC. Results showed that alpha-TS induced chromosomal damage in both human cervical cancer cells and ovarian cancer cells, but not in human normal fibroblasts in culture. In addition, alpha-TS enhanced the level of radiation-induced chromosomal damage in cancer cells, but it protected normal cells against such damage. Both cancer cells and normal cells accumulated similar levels of alpha-TS, suggesting that increased sensitivity of cancer cells to alpha-TS is acquired during transformation. The use of alpha-TS during radiation therapy may improve the efficacy of radiation therapy by enhancing tumor response and decreasing some of the toxicities on normal cells.
