Hydrogen peroxide reduces lead-induced oxidative stress to mouse brain and liver.

Bull Environ Contam Toxicol 82(4):419-22 (2009) PMID 18974911

Lead (Pb) intoxication may initiate many disorders in human and animals. This study investigates the role of exogenous hydrogen peroxide (H(2)O(2)) in inducing mouse tolerance to Pb exposure. Results showed that the simultaneous application of 1.2 microg H(2)O(2) per kg body weight efficiently protected mice against the Pb-caused injury, as revealed by decreased growth suppression caused by the Pb stress, increased antioxidative enzyme activity, reduced lipid peroxidation, and the protective effect on the nuclear DNA integrity. To our knowledge, this is the first finding of this sort.

    We show that the miR-181 family is developmentally regulated and present in high amounts in astrocytes compared to neurons. Overexpression of miR-181c in cultured astrocytes results in increased cell death when exposed to lipopolysaccharide (LPS). We show that miR-181 expression is altered by exposu...
  3. Antioxidant response of soybean seedlings to joint stress of lanthanum and acid rain.

    Environ Sci Pollut Res Int (2013) PMID 23653318

    We studied antioxidant response of soybean leaves and roots exposed to lanthanum (0.06, 0.18, and 0.85 mmol L(-1)) under acid rain conditions (pH 4.5 and 3.0). We found that low concentration of La(3+) (0.06 mmol L(-1)) did not affect the activity of antioxidant enzymes (catalase and peroxidase)...
