Epigenetic modifications from arsenic exposure: A comprehensive review.

Area of Science:

• Environmental Toxicology
• Epigenetics
• Molecular Biology

Background:

• Arsenic exposure is a global health concern, particularly in South and Southeast Asia.
• Arsenic causes various health problems, including cancer and non-cancerous conditions.
• While arsenic's genotoxicity is well-studied, its epigenetic effects are a recent focus.

Purpose of the Study:

• To review the mechanisms of arsenic-induced epigenetic alterations.
• To understand how arsenic exposure reprograms the epigenome, affecting cell signaling and epigenetic components.
• To propose novel therapeutic strategies for arsenic poisoning.

Main Methods:

• Literature review of arsenic-induced epigenetic changes.
• Analysis of mechanisms underlying epigenome reprogramming by arsenic.
• Synthesis of mechanistic information to inform therapeutic development.

Main Results:

• Arsenic exposure can lead to significant epigenetic modifications.
• These modifications disrupt normal cellular signaling pathways.
• Dysfunction of key epigenetic regulators is a consequence of arsenic exposure.

Conclusions:

• Understanding arsenic's epigenetic mechanisms is crucial for addressing arsenic poisoning.
• Novel therapeutic strategies targeting epigenetic pathways show promise.
• Further research can lead to effective interventions for arsenic-induced health effects.
