WebSerotoninergic system is shown to have a negative feedback on the GnRH biosynthesis, but still, the effect of serotonin on GnRH mRNA expression in females is unknown (Li and Pelletier, 1992). Additionally, noradrenaline represents dual effects on GnRH, and LH secretion according to steroid level status (Kalra, 1993). WebGnRH plays a key role in the vertebrate reproductive system by stimulating biosynthesis and secretion of pituitary gonadotropins. However, the potential involvement of microRNAs (miRNAs) on this activation has still to be explored. In this study, we investigated the role of miRNA-132 and miRNA-212, two tandemly expressed miRNAs that target the ...

WebApr 1, 2005 · In addition to GnRH-I, a second GnRH subtype (termed GnRH-II) that was originally identified from chicken hypothalamus has been found in humans (15, 16). This second GnRH form differs from GnRH-I by three amino acid residues at positions 5, 7, and 8 (His 5 Trp 7 Tyr 8 GnRH-I) and is conserved from primitive fish to humans (16, 17).
