Influence of steroid hormones on plasma proteins in freshwater tilapia Oreochromis mossambicus.
The effect of administration of cortisol, corticosterone, testosterone, progesterone and a synthetic estrogen, diethylstilbestrol on plasma proteins of tilapia (Oreochromis mossambicus) was investigated. SDS-PAGE clearly revealed the appearance of several new bands of protein, which were not present in the control plasma and were comparable to the known bands of the molecular markers. Of the different bands appeared in the steroids treated plasma, the most important ones were the presumed vitellogenin and corticotrophin binding globulin with a molecular weight of 180 and 17 kDa, respectively. Increase in protein bands in the steroid treated plasma of O. mossambicus confirmed the anabolic role of steroids in teleost.
