The cDNA encoding the follicle stimulating hormone beta subunit (FSH-β) was isolated from a red kangaroo pituitary cDNA library by using a porcine probe and the nucleotide sequence for the coding region was determined. The highest degree of deduced amino acid sequence identity (91%) was observed between the red kangaroo and another marsupial, the brushtail possum (Trichosurus vulpecula), followed by eutherian species (76%, 75% and 74%, respectively, for pig, mouse and sheep). Based on the deduced red kangaroo FSH-β amino acid sequence, putative antigenic sites have been identified that may prove useful for studying the hormonal control of reproduction in marsupials.

Subunit Gene

Reverse transcription–PCR has been used to obtain a cDNA sequence from the follicle-stimulating hormone (FSH) β-subunit gene of the Australian brushtail possum (Trichosurus vulpecula). Comparisons of the possum FSHβ-mRNA coding region nucleotide sequence with that of six eutherian mammal homologues reveals a mean percent identity of 77·3% and 76·8% at the nucleotide and predicted amino acid-sequence levels respectively. Furthermore, the predicted amino acid sequence of the possum FSHβ mature protein shows evolutionary conservation of twelve cysteine residues and two potential N-linked glycosylation sites. The protein lacks the CAGY motif present in most reported glycoprotein β-subunit sequences. The translation termination codon and consensus polyadenylation sequence overlap, a feature observed in other mammalian FSHβ genes. Northern hybridization of total RNA from adult female possum pituitary revealed three hybridizing transcripts of approximately 2·8, 1·2 and 0·5 kb which may arise from utilizing alternative polyadenylation signals. In situ hybridization localized the FSHβ transcripts to a sub-population of anterior pituitary cells interpreted as being gonadotropes. In summary the results indicate considerable evolutionary conservation of the structure of the FSH b-subunit gene between the marsupial and eutherian mammalian lineages.

Stimulating Hormone

Mammalian reproduction is mainly driven and regulated by the hypothalamic-pituitary-gonadal (HPG) axis. Follicle-stimulating hormone (FSH), which is synthesized and secreted by the anterior pituitary gland, is a key regulator that ultimately affects animal fertility. As a dimeric glycoprotein hormone, the biological specificity of FSH is mainly determined by the β subunit. As research techniques are being continuously innovated, studies are exploring the underlying molecular mechanism regulating the secretion of mammalian FSH. This article will review the current knowledge on the molecular mechanisms and signaling pathways systematically regulating FSH synthesis and will present the latest hypothesis about the nuclear cross-talk among the various endocrine-induced pathways for transcriptional regulation of the FSH β subunit. This article will provide novel ideas and potential targets for the improved use of FSH in livestock breeding and therapeutic development.
