Protective effect of luteinizing hormone on frozen-thawed ovarian follicles and granulosa cells.

open access: yesPLoS ONE
Ovarian tissue cryopreservation addresses critical challenges in fertility preservation for prepubertal female cancer patients, such as the lack of viable eggs and hormonal deficiencies.

Overexpression of CDC25C affects the cell cycle of ovarian granulosa cells from adult and young goats

open access: yesElectronic Journal of Biotechnology, 2018
Background: CDC25 is a dual-specificity phosphatase that was first identified in the yeast Schizosaccharomyces pombe as a cell cycle-defective mutant. Although CDC25 is involved in the cell cycle of ovarian granulosa cells, the CDC25 signaling pathway ...

Effect of Insulin-Like Growth Factor-1 (IGF-1) on the expression of NFκB and cFLIP in Bovine Granulosa Cells [PDF]

open access: yes, 2014
Infertility, often attributed to follicular atresia, is a growing problem in the agricultural industry. Programmed cell death, also known as apoptosis, is a contributing factor of follicular atresia.

Multi-scale modeling of follicular ovulation as a reachability problem [PDF]

open access: yes, 2007
During each ovarian cycle, only a definite number of follicles ovulate, while the others undergo a degeneration process called atresia. We have designed a multi-scale mathematical model where ovulation and atresia result from a hormonal controlled ...

Large‐Scale Quantitative Morphometry of Platelet α‐Granules via SIM Super‐Resolution Microscopy for Cancer Liquid Biopsy

open access: yesAdvanced Science, EarlyView.
ABSTRACT Blood‐based liquid biopsies hold transformative potential for non‐invasive cancer management, but current approaches relying on rare circulating tumor components limit their broad clinical utility. Platelets, abundant in blood and mediating diverse cancer‐associated responses, represent a compelling yet largely unexplored alternative.

Impact of In Vitro Long-Term Low-Level DEHP Exposure on Gene Expression Profile in Human Granulosa Cells

open access: yesCells, 2022
Here, we applied a model of long-term exposure of human granulosa cells to low environmentally relevant levels of di(2-ethylhexyl) phthalate (DEHP). This approach provides more relevant data regarding the impact of DEHP on the function of human granulosa

Fosl2 Regulates FSH‐Dependent Follicle Maturation Through Feedback Amplification of FSH/FSHR Signaling

open access: yesAdvanced Science, EarlyView.
This study identifies a FOSL2‐driven positive feedback loop that amplifies FSH/FSHR signaling. During FSH‐dependent follicle maturation, FSH induces Fosl2 expression via the cAMP‐PKA‐CREB cascade. FOSL2 in turn binds the promoters of Fshr and estrogen‐biosynthesis genes to enhance their transcription, thereby increasing Fshr mRNA level and amplifying ...

Intrinsic differences in mTOR activity mediates lineage-specific responses to cyclophosphamide in mouse and human granulosa cells

open access: yesJournal of Ovarian Research
Background Cyclophosphamide (CTX) often induces oocyte and granulosa cell injury, leading to fertility loss in young female cancer survivors. Deciphering the mechanisms underlying follicular cell injury could offer novel insights into fertility ...

Epidermal growth factor receptor signaling uncouples germ cells from the somatic follicular compartment at ovulation

open access: yesNature Communications, 2021
Uncoupling of mature oocytes from somatic granulosa cells is required for their fertilization. Here the authors show that activation of EGFR signalling in granulosa cells during ovulation triggers ERK-dependent loss of filopodia oocyte adhesion, and Arp2/

Natural Resistance to Ovarian Hyperstimulation Syndrome in Estrildid Finches Reveals Macrophage GPR183 as a Potential Therapeutic Target

open access: yesAdvanced Science, EarlyView.
Ovarian macrophage depletion reverses OHSS resistance in estrildid finches and exacerbates OHSS symptoms in rats. Activating macrophage GPR183 alleviates OHSS by reducing pro‐inflammatory factors, increasing immunomodulatory molecules, remodeling CD44/SDC4‐mediated communication, and restoring immune homeostasis.
