Extraovarian granulosa cell tumor

Indian Journal of Pathology and Microbiology, 2009
Extraovarian granulosa cell tumor (GCT) is a very uncommon tumor, assumed to arise from the ectopic gonadal tissue along the embryonal route of the genital ridge. One such rare case of extraovarian GCT was encountered in a 58-year-old female who presented with a large intraabdominal lump.

Histological Characterization and Comparative Transcriptomic Analysis of Gonads During Early Sex Differentiation in the Northern Snakehead (Channa argus)

Animal Research and One Health, EarlyView.
This study delineates the early sex differentiation timeline in the northern snakehead (Channa argus). These findings provide a foundation for future sex‐control breeding in this economically important species. ABSTRACT The northern snakehead (Channa argus) is an economically important aquaculture species in China.

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

Journal 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 ...

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope

Animal Research and One Health, EarlyView.
FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable

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

Nature 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/

Modern competency‐based teaching of human sexual development

Anatomical Sciences Education, EarlyView.
Abstract Embryology is an integral part of anatomy and a key subject in basic medical education. The development of the sexual tract, which is closely associated with the formation of the urinary tract and the organs of continence, is particularly complex and relevant for many medical disciplines.

Oocyte–cumulus cell interaction: a key factor in early embryo development

Biological Reviews, EarlyView.
ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.

Ameliorative Effect of Itaconic Acid/IRG1 Against Endoplasmic Reticulum Stress-Induced Necroptosis in Granulosa Cells via PERK-ATF4-AChE Pathway in Bovine

Cells
The necroptosis of granulosa cells has been proven to be one of the important triggers of follicular atresia, which is an important cause of reduced reproductive capacity in cows.

Acupuncture regulates the apoptosis of ovarian granulosa cells in polycystic ovarian syndrome-related abnormal follicular development through LncMEG3-mediated inhibition of miR-21-3p

Biological Research, 2023
Background The main features of polycystic ovary syndrome (PCOS) are abnormal follicular development and ovulatory dysfunction, which are caused by excessive apoptosis of ovarian granulosa cells.

Oogenesis and germinal bed morphology of the brown anole (A. sagrei)

Developmental Dynamics, EarlyView.
Abstract Background The brown anole is a model species of the genus Anolis, a squamate (encompassing lizards and snakes) group widely studied in evolutionary, behavioral, and developmental biology. Full genome annotation, the establishment of gene editing techniques, and comprehensive description of reproductive tract morphology and embryogenesis in ...
