Arsenic is an environmental toxicant. Its overdose can cause liver damage. Autophagy has been reported to be involved in arsenite (iAs3+) cytotoxicity and plays a dual role in cell proliferation and cell death. However, the effect and molecular regulative mechanisms of iAs3+ on autophagy in hepatocytes remains largely unknown. Here, we found that iAs3+ exposure lead to hepatotoxicity by inducing autophagosome...
Arsenic, an established human carcinogen, causes genetic toxicity. However, the molecular mechanisms involved remain unknown. MicroRNAs (miRNAs) are regulators that participate in fundamental cellular processes. In the present investigation, we selected, as research subjects, patients with arsenic poisoning caused by burning of coal in Guizhou Province, China. For these patients, the plasma levels...
