In this study, subchronic inhalation toxicity of HTP aerosols for 90 days was performed to assess its health risk of kidney. The nose-only exposure experiments were performed with SD rats. All the rats were randomly divided into sham, HTP (HTP_10, HTP_23, and HTP_50), and CS (Cig_23) groups. After exposure, the blood and kidney were prepared to detect its redox state, biomarkers in the early injury, apoptosis, and histopathology. The results showed that HTP and cigarette smoke both induced the expression of biomarkers including kidney injury molecule-1, neutrophil gelatinase-associated lipocalin, interleukin 18, and oxidative stress. For biochemical markers associated with kidney function, CS induced increased creatinine and urea for female rats and uric acid decreased, while HTP exposure only induced the upregulation of creatinine. Moreover, no obvious apoptosis and pathology of kidney were observed after HTP exposure, which indicated that HTP exposure may induce some biomarkers in the early stage of kidney injury without more serious changes. Overall, these results suggested that HTP with high concentration exposure showed potential slight health risks of kidney.","PeriodicalId":11333,"journal":{"name":"Drug and Chemical Toxicology","volume":" ","pages":"1-10"},"PeriodicalIF":2.1,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144474266","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}

However, repeated oral administration of TLAF (540 mg/kg) to beagle dogs for 28 days can cause 50% of administered animals to die.

For the toxicity study, forty adult male rats were divided into four groups.

Results showed that TCS exposure caused significant alteration in sperm parameters, and reduced antioxidant enzyme activity while increasing the concentration of oxidative stress markers. Moreover, DNA integrity was compromised along with testicular histopathological damage and lowered levels of reproductive hormones. Fertility test revealed reduced pregnancy outcomes and small litter sizes in females paired with TCS-treated males. RE treatment effectively normalized the attributes of sperm parameters and enzymatic activities of antioxidants. Additionally, co-treatment of RE restored the hormonal levels thus normalizing testicular architecture. Increased pregnancy outcomes and litter size in RE-treated animals were also recorded.

Mice were randomly divided into four groups (n = 10) which received daily intraperitoneal injections of either saline, 1 or 3 mg/kg of MPA, or 1 mg/kg of METH for 7 days. The novel object recognition test (NORT) revealed a significant decline in recognition memory, particularly evident at a dose of 3 mg/kg of MPA, similar to METH at 1 mg/kg, observed 24 h post-withdrawal. MPA at 3 mg/kg also impaired working and reference memory performance in the 8-arm radial maze (8-ARM) test and exhibited an anxiolytic effect in the open field test (OFT). These cognitive impairments were accompanied by decreased dopaminergic parameters and p-ERK1/2 expression within the prefrontal cortex (PFC). This further suggests that MPA neurotoxicity is targeted at the dopaminergic transmission in the PFC. In conclusion, MPA consumption is associated with memory impairment, which is attributable to dopaminergic deficits and reduced p-ERK1/2 activities in the PFC.","PeriodicalId":11333,"journal":{"name":"Drug and Chemical Toxicology","volume":" ","pages":"1-11"},"PeriodicalIF":2.1,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144309643","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}

Reverse transcription-PCR (RT-PCR) and Western blotting were employed to assess gene expression at the mRNA and protein levels. As early as 4 hours after exposure, DMBA caused increased DNA synthesis and consequent hypertrophy, which was followed by overexpression of ODC, c-Myc, PCNA, and Cox-2. It gradually decreases at the end of the 24-hour period following exposure to DMBA, after peaking at the end of the 16-hour period.

A retrospective analysis was performed on 50 breast cancer patients who developed ANT-associated cardiac dysfunction. Clinical assessments included measurements of left ventricular ejection fraction (LVEF) and serum markers, such as cardiac troponin I (cTnI), creatine kinase-MB (CK-MB), N-terminal pro-B-type natriuretic peptide (NT-proBNP), and serum iron levels. Serum analysis revealed a marked downregulation of lncRNA H19 and upregulation of Hmox1, both significantly correlated with impaired cardiac function and disrupted iron homeostasis. To further elucidate the mechanism, an Epirubicin (EPI)-induced injury model in HL-1 cardiomyocytes was established. EPI exposure led to suppression of lncRNA H19, upregulation of Hmox1, and induction of apoptosis and ferroptotic cell death. RNA-seq analysis identified potential downstream targets linking lncRNA H19 to iron metabolism via Hmox1 modulation. Functional assays demonstrated that overexpression of lncRNA H19 mitigated EPI-induced ferroptosis, while enforced expression of Hmox1 reversed these protective effects. Collectively, these findings identify the lncRNA H19/Hmox1 axis as a critical regulator of ferroptosis in ANT-induced cardiotoxicity and suggest it as a potential therapeutic target for mitigating cardiac injury in breast cancer patients undergoing anthracycline chemotherapy.","PeriodicalId":11333,"journal":{"name":"Drug and Chemical Toxicology","volume":" ","pages":"1-12"},"PeriodicalIF":2.1,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144157420","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}
