Sub-chronic cadmium and lead compound exposure induces reproductive toxicity and development of testicular germ cell neoplasia in situ in murine model: Attenuative effects of resveratrol.

Cadmium and lead are widespread, nonbiodegradable heavy metals of perpetual environmental concerns. The present study aimed to evaluate whether sub-chronic exposure to cadmium chloride (CdCl ) and lead acetate [Pb(CH COO) ] induces reproductive toxicity and development of testicular germ cell neoplasia in situ (GCNIS) in swiss albino mice. The effects of resveratrol to reverse the metal-induced toxicity were also analyzed.

Lead and cadmium exposure induces male reproductive dysfunction by modulating the expression profiles of apoptotic and survival signal proteins in tea-garden workers.

The aim of this study was to evaluate the impact of Lead (Pb) and Cadmium (Cd) exposure at the molecular level on the reproductive status of tea garden workers in North-East India. Using semen samples, we experimentally determined sperm analysis as well as oxidative stress parameters in all samples and evaluated the expression levels of apoptotic and cell survival proteins [p53, phospho-Akt, nuclear factor-κB (NF-κB, p50 subunit) and B cell lymphoma 2 (Bcl2)]. Our data revealed significant differences in the average heavy metal concentrations and various semen analysis profile between the infertile and normal groups.

Madhuca indica Inhibits Breast Cancer Cell Proliferation by Modulating COX-2 Expression.

Background: Madhuca indica belongs to the family sapotaceae, commonly known as Mahua. It is primarily known for alcoholic beverage production and is reported to have anti-inflammatory, analgesic and antipyretic properties. Madhuca indica has also been reported to be effective in several diseases.

Resveratrol Alleviates Cadmium-Induced Damage and Overexpression of Epidermal Growth Factor Receptor and its Downstream Signaling Proteins in the Reproductive System of Male Swiss Albino Mice.

Nowadays, exposure to heavy metals and their detrimental effects in humans are grave health concerns. In this study, we investigated the protective effect of resveratrol (RES) against CdCl2 (cadmium chloride)-induced impairment of spermatogenesis, histopathological alterations, and the up-regulation of epidermal growth factor receptor (EGFR) signaling cascade in Swiss albino mice. Two different doses of CdCl2 were injected intraperitoneally into two groups of mice, and in the third group RES was administered orally before injecting CdCl2 (3 times/wk) for 14 days.
