Hepatic lipid metabolism disorders and immunotoxicity induced by cysteamine in early developmental stages of zebrafish. Toxicology 2023; 493:153555. [PMID: 37236339 DOI: 10.1016/j.tox.2023.153555] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2023] [Revised: 05/13/2023] [Accepted: 05/23/2023] [Indexed: 05/28/2023]
Abstract
Cysteamine, a sulfhydryl compound, is an intermediate in the metabolism of coenzyme A to taurine in living organisms. However, the potential side effects of cysteamine such as hepatotoxicity in pediatric patients have been reported in some studies. To evaluate the impact of cysteamine on infants and children, larval zebrafish (a vertebrate model) were exposed to 0.18, 0.36 and 0.54mM cysteamine from 72 hpf to 144 hpf. Alterations in general and pathological evaluation, biochemical parameters, cell proliferation, lipid metabolism factors, inflammatory factors and Wnt signaling pathway levels were examined. Increased liver area and lipid accumulation were observed in liver morphology, staining and histopathology in a dose-dependent manner with cysteamine exposure. In addition, the experimental cysteamine group exhibited higher alanine aminotransferase, aspartate aminotransferase, total triglyceride and total cholesterol levels than the control group. Meanwhile, the levels of lipogenesis-related factors ascended whereas lipid transport-related factors descended. Oxidative stress indicators such as reactive oxygen species, MDA and SOD were upregulated after cysteamine exposure. Afterwards, transcription assays revealed that biotinidase and Wnt pathway-related genes were upregulated in the exposed group, and inhibition of Wnt signaling partially rescued the abnormal liver development. The current study found that cysteamine-induced hepatotoxicity in larval zebrafish is due to inflammation and abnormal lipid metabolism, which is mediated by biotinidase (a potential pantetheinase isoenzyme) and Wnt signaling. This provides a perspective on the safety of cysteamine administration in children and identifies potential targets for protection against adverse reactions.

Zhuang Z, Ding R, Qiu Y, Wu J, Zhou S, Quan J, Zheng E, Li Z, Wu Z, Yang J. A large-scale genome-wide association analysis reveals QTL and candidate genes for intramuscular fat content in Duroc pigs. Anim Genet 2021; 52:518-522. [PMID: 34060118 DOI: 10.1111/age.13069] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/10/2021] [Indexed: 01/30/2023]
Abstract
This study aimed at identifying genomic regions and genes associated with intramuscular fat content (IMF) in Duroc pigs using a weighted single-step GWAS. Data from 3912 pigs, of which 3770 animals were genotyped with GeneSeek Porcine 50K Bead chip, were used for the association analysis. We identified 19 genomic regions that each explained >1% of the additive genetic variance associated with IMF. Notably, a consistent QTL on SSC7 (117.42-117.92 Mb) was confirmed, explaining 3.70% of the additive genetic variance, and two genes, BDKRB2 and ATG2B, were highlighted as promising candidates for IMF. Two QTL (SSC7, 94.19-94.64 Mb; SSC14, 123.25-123.75 Mb), which harbored MED6 and MAP3K9 genes and TCF7L2 gene respectively, were newly identified as associated with IMF. In conclusion, we identified a consistent QTL and additional genomic regions and genes that contributed to the genetic variance of IMF using a large-scale sample size of genotyped pigs and genealogical information.
