Vitamin C pretreatment protects from nickel-induced acute nephrotoxicity in mice.

Nickel is an abundant carcinogenic and nephrotoxic metal whose activity leads to renal impairment. Previous studies have shown a protective effect of simultaneous vitamin C administration on acute and chronic nickel toxicity. However, very little research relating to the effect of vitamin C pretreatment in preventing nickel-induced acute nephrotoxicity is available.

Nickel-induced cell death and survival pathways in cultured renal proximal tubule cells: roles of reactive oxygen species, ceramide and ABCB1.

Nickel and nickel compounds are carcinogens that target the lungs and kidneys causing cell death or cell survival adaptation. The multidrug resistance P-glycoprotein ABCB1 protects cells against toxic metabolites and xenobiotics and is upregulated in many cancer cell types. Here, we investigated the role of ABCB1 in nickel-induced stress signaling mediated by reactive oxygen species (ROS) and ceramides.

2.45-Gz wireless devices induce oxidative stress and proliferation through cytosolic Ca²⁺ influx in human leukemia cancer cells.

Purpose: Electromagnetic radiation from wireless devices may affect biological systems by increasing free radicals. The present study was designed to determine the effects of 2.45 GHz radiation on the antioxidant redox system, calcium ion signaling, cell count and viability in human leukemia 60 cells.
