Pivotal role of High-Mobility Group Box 2 in ovarian folliculogenesis and fertility

Journal of Ovarian Research, 2022
Background High-Mobility Group Box 1 (HMGB1) and HMGB2 are chromatin-associated proteins that belong to the HMG protein family, and are involved in the regulation of DNA transcription during cell differentiation, proliferation and regeneration in various

Myrianthus arboreus P. Beauv (Cecropiaceae) Extracts Accelerates Sexual Maturation, and Increases Fertility Index and Gestational Rate in Female Wistar Rats

Medicines, 2018
Background: Despite the wide use of leaves of Myrianthus arboreus (Cecropiaceae) in several African countries including Cameroon as food and against amenorrhea and female infertility, it has never been tested for this purpose.

An oocentric view of folliculogenesis and embryogenesis

Reproductive BioMedicine Online, 2007
The mammalian oocyte undertakes a highly complex journey to maturity during which it successively acquires a series of characteristics necessary for fertilization and the development of a healthy embryo. While the contribution of granulosa cells to oocyte development has been studied for many years, it has recently become apparent that the oocyte ...

Increased Formation of Follicular Antrum in Aquaporin-8-Deficient Mice Is Due to Defective Proliferation and Migration, and Not Steroidogenesis of Granulosa Cells

Frontiers in Physiology, 2018
Aquaporin-8 (AQP8) is a water channel protein expressed exclusively in granulosa cells (GCs) in mouse ovary. Our previous studies of AQP8-deficient (AQP8-/-) mice demonstrated that AQP8 participates in folliculogenesis, including in the formation of ...

Unique morphological characteristics in the ovary of cotton rat (Sigmodon hispidus)

The Journal of Reproduction and Development, 2020
Cotton rats (Sigmodon hispidus, CRs) are commonly used as animal models in biomedical research. However, the reproductive characteristics and ovarian development in the CRs has not been widely investigated.

Integrative Transcriptome Analysis Across Follicles Highlights Key Regulatory Pathways in Low and High-Egg-Laying Hens

Animals
Egg-laying performance in hens is regulated by complex molecular mechanisms within the hypothalamic–pituitary–gonadal (HPG) axis and ovarian follicles. This study employed integrative transcriptome profiling of primordial (PR), primary (PM), small white (

Folliculogenesis and Abnormalities

Journal of Gynecology Research Reviews & Reports
Research on oocytes and their associated follicles has advanced significantly over the past two decades, shedding light on the fragility of the processes governing their active life. The ovarian follicles and the germ cells within them are crucial to understand conception, growth, and survival mechanisms.
