dc.description.abstract | Peroxiredoxins (Prxs) play an important role in regulating cellular differentiation and proliferation in several types of mammalian cells. One mechanism for this action involves modulation of hydrogen peroxide (H2O2)-mediated cellular responses. This report examines the expression of Prx I and Prx II: in thyroid cells and their roles in eliminating H2O2 produced in response to thyrotropin (TSH), Prx I and Prx II are constitutively expressed in FRTL-5 thyroid cells. Prx I expression, but not Prx II expression, is stimulated by exposure to TSH and H2O2. In addition, methimazole induces a high level of Prx I mRNA and protein in these cells, Overexpression of Prx I and Prx II enhances the elimination of H2O2 produced by TSH in FRTL-5 cells. Treatment with 500 mu M H2O2 causes apoptosis in FRTL-5 cells as evidenced big standard assays of apoptosis the. terminal deoxynucleotidyl transferase deoxyuridine triphosphate-biotin nick end labeling, BAX expression, and poly(ADP-ribose) polymerase cleavage. Overexpression of Prx I and Prx II reduces the amount of H2O2-induced apoptosis measured by these assays. These results suggest that Prx I and Prx LI are involved in the removal of H2O2 in thyroid cells and can protect these cells from undergoing apoptosis. These proteins are likely to be involved in the normal physiological response to TSH-induced production of H2O2 in thyroid cells. | - |
