Abstract
Disinfection byproducts (DBPs) are a class of ubiquitous chemicals in drinking water and inevitably result in widespread human exposures. Potentially adverse health effects of DBP exposures, including reproductive and developmental outcomes, have been increasing public concerns. Several reviews have focused on the adverse pregnancy outcomes of DBPs. This review summarized current evidence on male reproduction health upon exposure to DBPs from toxicological and epidemiological literature. Based on existing experimental studies, there are sufficient evidence showing that haloacetic acids (HAAs) are male reproductive toxicants, including reduced epididymal weight, decreased semen parameters and sperm protein 22, and declined testosterone levels. However, epidemiological evidence remains insufficient to support a link of DBP exposures with adverse male reproductive outcomes, despite that blood and urinary DBP biomarkers are associated with decreased semen quality. Eight potential mechanisms, including germ/somatic cell dysfunction, oxidative stress, genotoxicity, inflammation, endocrine hormones, folate metabolism, epigenetic alterations, and gut microbiota, are likely involved in male reproductive toxicity of DBPs. We also identified knowledge gaps in toxicological and epidemiological studies to enhance future needs.

Abstract
Ectoderm and mesoderm can be considered as prototypes for epithelial and mesenchymal cell types. These two embryonic tissues display clear differences in adhesive and motility properties, which are phenomenologically well characterized but remain largely unexplored at the molecular level. Because the key downstream regulations must occur at the plasma membrane and in the underlying actin cortical structures, we have set out to compare the protein content of membrane fractions from Xenopus ectoderm and mesoderm tissues using 2-dimensional difference gel electrophoresis (DiGE). We have thus identified several proteins that are enriched in one or the other tissues, including regulators of the cytoskeleton and of cell signaling. This study represents to our knowledge the first attempt to use proteomics specifically targeted to the membrane-cortex compartment of embryonic tissues. The identified components should help unraveling a variety of tissue-specific functions in the embryo.

[PMID: 16935423 DOI: 10.1016/j.neulet.2006.06.067] [Citation(s) in RCA: 22] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2006] [Revised: 06/16/2006] [Accepted: 06/30/2006] [Indexed: 01/13/2023]
Abstract
DJ-1 was initially identified by us as a novel oncogene and has recently been found to be a causative gene for familial Parkinson's disease (PD) PARK7. DJ-1 plays roles in transcriptional regulation and in oxidative stress function, and its oxidative state at cysteine residues determines activities of DJ-1. In this study, we found that recombinant DJ-1 expressed in and purified from E. coli was specifically cleaved between glycine and proline at amino acid numbers 157 and 158, respectively, by treatment of DJ-1 with H2O2. A substitution mutant of DJ-1 from cysteine to serine at amino acid number 106, a major oxidation site of DJ-1, was found not to be cleaved under an oxidative condition, suggesting oxidation-dependent cleavage of DJ-1. Cleavage of DJ-1 was also observed in human SH-SY5Y cells that had been treated with H2O2. These results suggest that oxidative stress-induced cleavage of DJ-1 regulates functions of DJ-1.
