Background: Deep suppression of LH in GnRH antagonist cycles may have detrimental effect on reproductive out come. It was hypnotized that adding LH activity via the administration of low dose HCG in late follicular phase shortened the duration of stimulation, decreased consumption of gonadotropin and increased estrogen levels. This study was designed to evaluate the effect of adding low dose HC...
Follicle stimulating hormone (FSH) is a glycoprotein hormone with subunitsαandβ, and is required for gamete development. Differential glycosylation may produce diglycosylated FSH with higher biological activity, and is suspected to be generated via the action of oligosaccharyltransferase(OST) isoforms. Signal peptide hydrophobicity of α and β maycontribute to selective usage of OST, and hence m...
Specific reversed-phase high-performance liquid chromatography conditions are reported for the analysis of recombinant and native human luteinizing hormone (hLH) and human chorionic gonadotropin (hCG) preparations. Heterodimeric hLH, hCG and their alpha- and beta-subunits migrated with significantly different retention times (t(R)) in the following order of increasing hydrophobicity: alpha-hCG<...
The morphology of hyperplastic pituitaries in seven human growth hormone-releasing factor (hGRF) transgenic mice were compared to those of two normal control mice. Under continuous stimulation by hGRF, both the total volume of the pituitary and the size of individual cells increased, and a nodular lesion, designated a "hypertrophic nodule", was identified. Immunohistochemically, the hyperplasti...
Two obelin mutants distinctly different in the color of bioluminescence were successfully applied to simultaneous detection of two analytes in a single well. The flash-type signals were triggered by single injection of Ca and were discriminated by the spectral and time resolutions. The technique was developed in a high-throughput format, and applied to simultaneous immunoassay of two gonadotrop...
Recombinant human follicle-stimulating hormone (r-hFSH) is widely used in fertility treatment. Although biosimilar versions of r-hFSH (follitropin alfa) are currently on the market, given their structural complexity and manufacturing process, it is important to thoroughly evaluate them in comparison with the reference product. This evaluation should focus on how they differ (e.g., active compon...
