Taurine (Tau), a sulfur-containing amino acid with cell membrane stabilization and antioxidant properties, may mitigate these effects. This study examined how Tau can protect against oxidative stress and apoptosis induced by Acr in mouse ovarian tissue. Forty adult healthy mice, aged 6-8 weeks, were randomly assigned to four groups including the controls (received normal saline orally), Acr (50 mg/kg/day Acr orally), Acr + Tau75 (Acr and 75 mg/kg/day Tau), and Acr + Tau150 (Acr and 150 mg/kg/day Tau). Treatments were administered for 35 days, followed by assessments of stress markers and apoptosis via immunofluorescence and TUNEL assays. Both doses of Tau significantly increased the gene and protein expression levels of stress response enzymes, including Gpx1, Sod1, and Cat. Moreover, Tau significantly decreased the gene expression levels of apoptotic markers Caspase3 and Bax, while upregulating the antiapoptotic gene Bcl2l2. The TUNEL assay revealed the preventive properties of Tau against Acr-induced apoptosis in the ovaries. The current findings suggest the promising properties of Tau in the prevention of Acr-induced oxidative stress and apoptosis in mouse ovarian tissue. Therefore, Tau could play a protective role against Acr-induced reproductive toxicity in females, meriting further research into its potential applications.","PeriodicalId":23171,"journal":{"name":"Toxicology and Industrial Health","volume":" ","pages":"282-293"},"PeriodicalIF":1.7,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143983214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In studies in experimental animals, VTMS showed a low acute toxicity via oral, dermal, and inhalation routes of exposure. VTMS is not a dermal or eye irritant. A weight of evidence assessment of four available dermal sensitization studies in guinea pigs supports the conclusion that VTMS is not a dermal sensitizer; however, based on one additional study that gave positive results, ECHA classified VTMS as Category 1B (may cause an allergic skin reaction). VTMS is not considered to be genotoxic based on results of in vitro and in vivo studies. In various experimental animal studies, VTMS has shown neither reproductive nor developmental effects. Short-term, oral administration of VTMS for 28 days in rats produced treatment-related effects in the urinary bladder and kidney. In a 14-week inhalation study in rats, VTMS exposure was associated with histopathological changes in the kidney and urinary bladder. However, an expert panel review of the urinary bladder and kidney observations concluded they were an adaptive response to physical or chemical irritant(s) in the urine.

This study investigated the toxic effects (DNA damage) of LCH exposure on zebrafish for 24 and 72 h. After zebrafish (Danio rerio) were obtained commercially, acclimated, and adapted to laboratory conditions. They were randomly selected, transferred to the experimental aquariums (their average height is 2.51 ± 0.49 cm long, 10 L aquarium size of 10x20x35), and exposed to 0.1 mg/L LCH concentrations for 24 and 72 h. There was also a control and a solvent control group in the study, and whole body tissues of zebrafish were analyzed for 8-hydroxy-2-deoxyguanosine (8-OhdG) determination (ng/100 mg tissue), using an Agilent LC-MS/MS with electrospray ionization in positive ion mode.

These results suggest that LCH could lead to oxidative DNA damage by causing an increase in 8-OHdG activities in zebrafish, one of the aquatic ecosystem model organisms, indicating that it may also cause undesirable effects on other non-target species.","PeriodicalId":23171,"journal":{"name":"Toxicology and Industrial Health","volume":" ","pages":"186-194"},"PeriodicalIF":1.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143190363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
