Hyaluronan and proteoglycans in ovarian follicles [PDF]

open access: yesHuman Reproduction Update, 1999
Proteoglycans are macromolecules formed by a protein backbone to which one or more glycosaminoglycan side chains are co-valently attached. They can be secreted by the cells, retained at the cell surface, or stored in intracellular vacuoles. Hyaluronan is an extremely long glycosaminoglycan which, at variance with other glycosaminoglycans, is released ...

A Microfluidic Device for Culturing an Encapsulated Ovarian Follicle

open access: yesMicromachines, 2017
Microfluidic chips have been proved effective in mimicking different organs of human body. Simulating human ovarian follicles by microfluidic device will be useful in exploring the mechanism of folliculogenesis and related diseases.

NAD+‐Dependent Enzyme SIRT3 Limits Intestinal Epithelial Cell Functions Through NAD+ Synthesis Pathway in Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
Microbiota‐derived quinolinic acid is used as an alternative source of replenishing the intracellular NAD+ pool induced by SIRT3 deficiency to regulate intestinal epithelial cell and T cell function, which has implications for targeting intestinal epithelial cells as an approach to the treatment of immune‐associated diseases, including colorectal ...

Monitoring of Ovarian Follicular Development and Ovulation with Transvaginal Sonography (TVS) in Infertile Women in Eastern Region of Nepal

open access: yesJournal of Nobel Medical College, 2016
Background Ultrasonography is the first line imaging modality for evaluation of ovaries, monitoring ovarian follicular development and detecting ovulation in infertile women; thus plays a significant role in infertility management.

Neurokinin B Regulates Gonadotropin Secretion, Ovarian Follicle Growth, and the Timing of Ovulation in Healthy Women

open access: yesJournal of Clinical Endocrinology and Metabolism, 2017
Context: Neurokinin B (NKB) is obligate for human puberty, but its role in adult female gonadotropin secretion and ovarian follicle growth is unknown.

HMGB2–RAD21 Axis Promotes Fibro/Adipogenic Progenitor Proliferation and Regulates Fat Infiltration

open access: yesAdvanced Science, EarlyView.
This study constructed the first developmental atlas of embryonic skeletal muscle fibro/adipogenic progenitors (FAPs) and identified an HMGB2+ FAPs subpopulation that regulates FAP pool size and muscle homeostasis. HMGB2 directly targets the RAD21 promoter, and its knockout significantly reduces FAP numbers, thereby lowering the potential for ...

Primordial follicle survival of goat ovarian tissue after vitrification and transplantation on chorioallanthoic membrane

open access: yesMiddle East Fertility Society Journal, 2020
Background Ovarian tissue vitrification is an alternative fertility preservation procedure for young female patients prior to gonadotoxic treatment. Primordial follicle loss might be a potential issue for vitrification and transplantation procedures ...

CPEB3 deficiency in mice affect ovarian follicle development and causes premature ovarian insufficiency

open access: yesCell Death and Disease, 2021
Premature ovarian insufficiency (POI) is a heterogeneous and multifactorial disorder. In recent years, there has been an increasing interest in research on the pathogenesis and treatment of POI, owing to the implementation of the second-child policy in ...

The Photoperiod Regulates Granulosa Cell Apoptosis through the FSH-Nodal/ALK7 Signaling Pathway in Phodopus sungorus

open access: yesAnimals, 2022
The photoperiod regulates the seasonal reproduction of mammals by affecting the follicle development, for which the granulosa cells provide nutrition. However, the underlying mechanism remains unclear.

Ovarian follicle burnout: A universal phenomenon? [PDF]

open access: yesCell Cycle, 2013
The ovarian follicle reserve is maintained in a delicate state of homeostasis aimed at preserving the majority of follicles in a dormant state. Key regulatory factors in follicle activation and quiescence include the PI3K/PTEN/Akt signaling pathway in the oocyte, as well as external paracrine inhibitory factors such as anti-Mullerian hormone (AMH) (Fig.
