Toxic Metals Increase Serum Tumor Necrosis Factor-α Levels, Modified by Essential Elements and Different Types of Tumor Necrosis Factor-α Promoter Single-nucleotide Polymorphisms.

Abstract excerpt

BACKGROUND: Lead (Pb), cadmium (Cd), and arsenic (As) could cause health issues through oxidative stress that is indicated in the elevated tumor necrosis factor-alpha (TNF-α). However, some of the essential elements-selenium (Se), zinc (Zn), cobalt (Co), and copper (Cu)-are cofactors or structural components of antioxidant enzymes. It is suggested that single-nucleotide polymorphisms (SNPs) in the TNF-α gene have...
