Chronic arsenic exposure is a major environmental health concern
currently affecting millions of people worldwide. Given the consequences
of arsenic on human health, this study explores the effects of arsenic
exposure in human population currently exposed to alarmingly high levels
of arsenic. Genome-wide gene expression pattern analysis provides strong
evidences for arsenic to be carcinogenic and to contribute to a
well-defined spectrum of diseases. We also identify a potential
bio-marker to arsenic induced carcinogenesis. This study thus provides
critical insights into modus operandi of the environmental toxin
arsenic. Also despite arsenic being a prominent health hazard, an
effective preventive measure for treating arsenic induced toxicity
eludes us. We document GARLIC to be an effective antidote to arsenic.
The restorative property of garlic was attributed to its antioxidant
activity, chelating efficacy, and/or oxidizing capability of trivalent
arsenic to its less toxic pentavalent form. We therefore identify garlic
as a potential protective regimen to arsenic induced-toxicity. We have
also discussed the paradoxical therapeutic potential of arsenic in this
book.
