Transformation and gene expression study of recombinant fish GnRH in E. coli BL21 in order to produce recombinant hormone
Gonadotropin releasing hormone (GnRH) is a neuropeptide known to regulate reproduction in vertebrates. Different analogues of synthetic GnRH are used to induce final sexual maturation in fish breeders. The purpose of this research was to evaluate the expression of recombinant GnRH (rGnRH) in Escherichia coli BL21 to produce recombinant hormone. In the present research, the sequence of DNA relat...

متن کاملIntermediary role of kisspeptin in the stimulation of gonadotropin-releasing hormone neurons by estrogen in the preoptic area of sheep brain
Introduction: The role of estrogen in the stimulation of gonadotropin-releasing hormone (GnRH) neurons is clear. These neurons do not express estrogen alpha receptors, so other mediator neurons should be present to transmit the positive feedback effect of estrogen to the GnRH neurons. Kisspeptin neurons have an important role in the stimulation of GnRH neurons, so they can be the mediator of...
متن کاملGonadotropin-releasing hormone and TGF-beta activate MAP kinase and differentially regulate fibronectin expression in endometrial epithelial and stromal cells.
Gonadotropin-releasing hormone analog (GnRHa) is used for medical management of endometriosis and premature luteinizing hormone surge during controlled ovarian stimulation. Human endometrium expresses GnRH receptors, and GnRHa alters the expression of transforming growth factor-beta (TGF-beta) and receptors in endometrial cells. Because the diverse biological actions of GnRHa and TGF-beta are m...
متن کاملp38/RK is essential for stress-induced nuclear responses: JNK/SAPKs and c-Jun/ATF-2 phosphorylation are insufficient
The ERK, JNK/SAPK and p38/RK MAP kinase subtypes (reviewed in [1]) are differentially activated in mammalian cells by various stimuli, which elicit induction of immediate-early (IE) genes, such as c-fos and c-jun (reviewed in [1-3]), as well as phosphorylation of histone H3 [4] and HMG-14 [5]. Anisomycin and UV radiation have been suggested to induce c-fos and c-jun transcription via JNK/SAPK-m...
