Functionally, LPO teams up with dual oxidases (DUOXs) to generate bactericidal hypothiocyanite in the presence of thiocyanate. DUOX2 is expressed in intestinal epithelium, but there is little information on LPO expression in this tissue. To fill the gap of knowledge, we have analyzed Lpo gene expression and its regulation in mouse intestine. In wild-type (WT) C57BL/6 (B6) mouse intestine, an appreciable level of mouse Lpo gene expression was detected in the colon, but not the ileum. However, in B6 mice deficient in glutathione peroxidase (GPx)-1 and -2, GPx1/2-double-knockout (DKO), which had intestinal pathology, the colon Lpo mRNA levels increased 5-to 12-fold depending on mouse age. The Lpo mRNA levels in WT and DKO 129S1/SvlmJ (129) colon were even higher, 9- and 5-fold, than in B6 DKO colon. Higher levels of Lpo protein and enzymatic activity were also detected in the 129 mouse colon compared to B6 colon. Lpo protein was expressed in the differentiated colon epithelial cells, away from the crypt base, as shown by immunohistochemistry. Similar to human LPO mRNA, mouse Lpo mRNA had multiple spliced forms, although only the full-length variant 1 was translated. Higher methylation was found in the 129 than in the B6 strain, in DKO than in control colon, and in older than in juvenile mice. However, methylation of the Lpo intragenic CpG island was not directly induced by inflammation, because dextran sulfate sodium-induced colitis did not increase DNA methylation in B6 DKO colon. Also, Lpo DNA methylation is not correlated with gene expression."xsd:string |
