Description
| - Mercury is a prominent environmental contaminant that causes endocrine disorder to human and other organisms. But little is known about the response of the thyroid functions and hypothalamic-pituitary-thyroid (HPT) axis to mercury in teleosts and the few studies that are available have not yielded consistent results. In this study, expression profiles of corticotropin-releasing hormone (crh), thyroid stimulating hormone beta (tsh beta), solute carrier family 5 (sodium iodide symporter) member 5 (slc5a5), thyroglobulin (tg), thyroid hormone receptor alpha (tr alpha) and thyroid hormone receptor beta (tr beta) genes were determined in whole-body of Chinese rare minnow (Gobiocypris Torus) larvae after exposure to different levels of Hg2+ (0, 0.1 and 0.3 mg/l) for 4 days, as well as the thyroid hormones (THs) levels. Moreover, the 96-h lethal concentration of Hg2+ on rare minnow larvae was determined as 0.32 mg/l. The results showed that crh, tg, tr alpha and tr beta mRNA levels were significantly up-regulated in the larvae, but the gene expression of tsh beta and slc5a5 was not significantly changed in our study. Besides, the THs levels increased in the whole-body of fish, especially the thyroxine (T4) level. The above results indicated that Hg2+ could alter some genes expression in the HPT axis which could be used as the potential biomarkers for evaluating the environmental Hg2+-induced stress in fish.
