Expression of the xenobiotic- and reactive oxygen species-detoxifying enzymes, GST-pi, Cu/Zn-SOD, and Mn-SOD in the endocrine cells of colorectal cancer.
This study analysed 12 single-nucleotide polymorphisms (SNPs) in selenoprotein genes [glutathione peroxidase 1 (GPX1), GPX4, 15 kDa selenoprotein (SEP15), selenoprotein S (SELS), selenoprotein P (SEPP1) and thioredoxin reductase 2 (TXNRD2)] and in genes that code for a key protein in Se incorporation [SECIS-binding protein 2 (SBP2)] and in antioxidant defence [superoxide dismutase 2 (SOD2)] in relation to sporadic CRC incidence.
We investigated whether this polymorphism of the MnSOD gene is associated with increased risk for colorectal cancer among Hispanics and non-Hispanic whites.
