چکیده انگلیسی
To obtain evidence of the presence of sex steroid hormones in mollusks, hormone variation in the gonads of the Zhikong scallop Chlamys farreri was analyzed using UPLC-MS/MS. These were found, as expected, with concentrations of estrone (E1), 17beta-estradiol (E2), and testosterone (T) in the testes ranging from not detected (ND) to 0.07 ± 0.10, ND to 3.10 ± 2.00, and ND to 2.67 ± 1.55 ng/g wet weight, respectively. In the ovaries, these hormones ranged from ND to 2.45 ± 1.22, ND to 27.90 ± 4.23, and ND to 2.38 ± 1.56 ng/g ww, respectively. The levels of T in males and E2 in females followed a trend similar to the gonadal-somatic index over the course of the reproductive period. In addition, the gene expression of vitellogenin and calmodulin-2 showed similar patterns to T and E2, while the estrogen receptors and calmodulin-1 did not. These results indicate that sex steroids are present in the scallop and that they may regulate endocrine functions during the reproductive process.
