Background:
This study aims at investigating the effect of growth hormone (GH) on the growth of human endometrial glandular cells (hEGCs) and preliminary exploring its mechanism.
Methods:
HEGCs were isolated from the endometrial biopsies and exposed to different dose of GH (0, 50, 100, and 200 ng/mL). Cell proliferation and cell cycle assay, migration assay was performed to investigate the growth and motivation of hEGCs, respectively. Reverse transcription-polymerase chain reaction (RT-PCR), immunocytochemistry (ICC), and western blot (WB) were processed to investigate its related gene or protein expression.
Results:
The results revealed that GH administration promoted the proliferation, cell cycle, migration, and growth hormone receptors (GHRs) expression of the hEGC. We further inhibited GHRs with AG490, and the inhibitor reversed the effects of GH on cell growth, motion, and the activation of GHR and STAT3/5.
Conclusions:
GH promoted hEGCs proliferation and motion, which is GHR-JAK-STAT3/5 signaling pathway-dependent. These findings reveal the essential roles of GH in the hEGCs growth and provide evidence for potential GH therapy in intrauterine adhesion (IUA) treatment.

01:22Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair...

01:22Target Cell Response to Hormones
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...
01:26Secondary Messengers in Hormone Action
Many hormones bind to transmembrane G protein-coupled receptors that connect to regulatory G proteins. These G proteins can then activate enzymes such as adenylyl cyclase or phospholipase C. Adenylyl cyclase converts ATP to cAMP, activating...
