A recently developed technology (xCelligence) integrating micro-electronics and cell biology allows real-time, uninterrupted and quantitative analysis of cell proliferation, viability and cytotoxicity by measuring the electrical impedance of the cell population in the wells without using any labeling agent. In this study we investigated if this system is a suitable model to analyze the effects of mitogenic (FSH) and cytotoxic (chemotherapy) agents with different toxicity profiles on human granulosa cells in comparison to conventional methods of assessing cell viability, DNA damage, apoptosis and steroidogenesis. The system generated the real-time growth curves of the cells, and determined their doubling times, mean cell indices and generated dose-response curves after exposure to cytotoxic and mitogenic stimuli. It accurately predicted the gonadotoxicity of the drugs and distinguished less toxic agents (5-FU and paclitaxel) from more toxic ones (cisplatin and cyclophosphamide). This platform can be a useful tool for specific end-point assays in reproductive toxicology.

Background: Granulosa cell proliferation and survival are essential for normal ovarian function and follicular development. Long non-coding RNAs (lncRNAs) have emerged as important regulators of cell proliferation and differentiation. Nuclear paraspeckle assembly transcript 1 (NEAT1) has been implicated in various cellular processes, but its role in granulosa cell function remains unclear.

Ovarian aging significantly impacts female fertility, with mitochondrial dysfunction emerging as a key factor. This study investigated the effects of recombinant follicle-stimulating hormone (FSH) and luteinizing hormone (LH) on mitochondrial function and metabolism in aging female reproductive cells. Human granulosa cells (HGL5) were treated with FSH/LH or not.

Diabetes mellitus (DM) causes numerous systemic diseases in animals and humans. This may also lead to reproductive problems among individuals of reproductive age. Detrimental effects such as apoptosis in ovarian granulosa cells, degradation of communication proteins, decreased oocyte quality, delayed meiotic maturation, and atrophy are among the increasing evidence that chronic hyperglycemia causes reproductive problems.

Gengnianchun (GNC) is a traditional remedy used for diminished ovarian reserve, but its underlying mechanisms remain unclear. This study aimed to explore these mechanisms in human granulosa-like cancer (KGN) cells pretreated with medicated rat serum (MRS) before HO exposure. MRS pretreatment significantly alleviated HO-induced cell damage, including improvements in cell viability, superoxide dismutase and GSH-Px activities, and Bcl-2 expression.

As one of the essential lignan derivative found in traditional Chinese medicinal herbs, secoisolariciresinol diglucoside (SDG) was proved to promote women's health through its phytoestrogenic properties. Increasingly studies indicated that this compound could be a potential drug capable of preventing estrogen-related diseases. Here, we aimed to investigate whether SDG can counteract cyclophosphamide (CTX) induced premature ovarian insufficiency (POI) and further explore its specific molecular mechanism.
