Comparative study on the transcriptional activities of grass carp (Ctenopharyngodon idellus) peroxisome proliferator-activated receptors induced by different fatty acids. Comp Biochem Physiol B Biochem Mol Biol 2024; 275:111021. [PMID: 39151662 DOI: 10.1016/j.cbpb.2024.111021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2024] [Revised: 08/13/2024] [Accepted: 08/13/2024] [Indexed: 08/19/2024]
Abstract
Peroxisome proliferator-activated receptors (PPARs) are ligand-activated transcription factors that are part of the nuclear hormone receptor family, playing a crucial role in gene expression regulation. They serve as a connection between lipid metabolism disorders and innate immunity by being activated by fatty acids and their derivatives, facilitating signal transduction between the cell surface and nucleus. However, the specific transcriptional effects of different fatty acids (FAs) in fish are not yet fully understood. In our research, we identified and characterized PPARs in grass carp (Ctenopharyngodon idellus). The complete coding sequences of pparαa, pparαb, pparγ, pparδa, and pparδb were 1443 bp, 1404 bp, 1569 bp, 1551 bp, and 1560 bp in length, respectively. Pparα showed the highest expression in the liver, pparγ was mainly expressed in abdominal adipose tissue, and pparδ exhibited increased expression in the heart compared to other tissues. Gene localization analysis revealed that only pparδa was present in both the nucleus and cytoplasm, while the other four genes were exclusively located in the nucleus. Furthermore, our study explored the influence of various fatty acids (docosahexaenoic acid, palmitic acid, lauric acid and oleic acid at concentrations of 0, 50, 100, and 200 μM) on the transcriptional activities of different PPARs, demonstrating the diverse effects of fatty acid ligands on PPAR transcriptional activity. These results have significant implications for understanding the regulation of PPARs transcriptional activity.

ENVIRONMENT INTERNATIONAL 2021; 154:106646. [PMID: 34049269 DOI: 10.1016/j.envint.2021.106646] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/10/2021] [Revised: 05/04/2021] [Accepted: 05/13/2021] [Indexed: 06/12/2023]
Abstract
Cadmium is a well-known hazardous pollutant that mainly comes from dietary, tobacco and occupational exposure, posing threat to kidney. However, there is still a lack of systematic study on metabolic pathways and urinary biomarkers related to its nephrotoxicity under cadmium exposure for both females and males. In this study, a mass spectrometry-based metabolomics investigation of a cohort of 144 volunteers was conducted to explore sex-specific metabolic alteration and to screen biomarkers related to cadmium-induced nephrotoxicity. When the concentration of urinary cadmium increased, creatine pathway, amino acid metabolism especially the tryptophan metabolism, aminoacyl-tRNA biosynthesis, and purine metabolism were primarily influenced regardless of the gender. Also, the most specific biomarkers linked with nephrotoxicity based on the statistical analysis were detected including creatine, creatinine, l-tryptophan, adenine and uric acid. The study outcome might provide information to reflect the body burden and help improve health policy for risk assessment.
