Exposure to individual phthalates disrupts ovarian function; however, the direct effects of phthalate mixture exposure on ovulation is unknown, especially in women. Human granulosa cells were used to test the hypothesis that exposure to a p…
Leukocytes are in situ regulators critical for ovarian function. However, little is known about leukocyte subpopulations and their interaction with follicular cells in ovulatory follicles, especially in humans. Single-cell RNA sequencing (s…
Exposure to phthalates disrupts ovarian function. However, limited studies have investigated the effects of phthalate mixtures on ovulation, especially in women. Human granulosa cells were used to test the hypothesis that exposure to a phth…
FOS, a subunit of the activator protein-1 (AP-1) transcription factor, has been implicated in various cellular changes. In the human ovary, the expression of FOS and its heterodimeric binding partners JUN, JUNB, and JUND increases in periov…
The midcycle surge of LH sets in motion interconnected networks of signaling cascades to bring about rupture of the follicle and release of the oocyte during ovulation. Many mediators of these LH-induced signaling cascades are associated wi…
The matrix metalloproteinases (MMPs) are postulated to facilitate ovulation by remodeling the follicular wall. The MMP family is comprised of 25 different proteinases, many of which share common structural and functional characteristics and…
The matrix metalloproteinase (MMP) family is believed to play a role in the ovulatory process because MMP inhibitors block oocyte release. However, little is known about the mechanisms by which the MMPs affect ovulation. The present study i…
Alterations in the interaction between the follicle and the matrix must occur before follicular rupture and ovulation can take place. Such interactions are controlled in part by the delicate balance between the matrix metalloproteinases (MM…
In the ovary, the matrix metalloproteinases (MMPs) and the tissue inhibitors of metalloproteinases (TIMPs) have been postulated to play a critical role in extracellular matrix remodeling associated with ovulation as well as luteal formation…
OBJECTIVE: To characterize the expression of basigin in ovarian endometriotic tissue, normal ovary, and endometrium during the menstrual cycle. DESIGN: Controlled, retrospective study for evaluation of basigin expression in archived specim…
OBJECTIVE: To evaluate the effects of a gonadotropin-releasing hormone agonist (GnRH-a) on plasminogen activator (PA), matrix metalloproteinase (MMP), plasminogen activator inhibitor (PAI) and matrix metalloproteinase inhibitor (MMPI) activ…
OBJECTIVE: Our purpose was to determine in the rat model whether endometriosis could influence ovarian function by altering oocyte release or folliculogenesis. STUDY DESIGN: We histologically examined the ovaries of reproductively cycling …
The influence of ovarian adrenergic nerves on follicular growth during the estrous cycle in the adult guinea pig was ascertained by comparing follicular development in control and chemically sympathectomized ovaries from the same animal. Se…
The structure of the human ovarian ligament was studied with light and electron microscopy, with emphasis on neural components. The ligament is primarily composed of smooth muscle arranged in an outer oblique and an inner longitudinal layer…
