Transcriptomic Analysis for Differentially Expressed Genes in Ovarian Follicle Activation in the Zebrafish

Frontiers in Endocrinology, 2018
In teleosts, the onset of puberty in females is marked by the appearance of the first wave of pre-vitellogenic (PV) follicles from the pool of primary growth (PG) follicles (follicle activation) in the ovary during sexual maturation.

Identifying Causes of Reproductive Failure in Zoo‐Housed Bush Dogs (Speothos venaticus) to Improve Ex Situ Management

Zoo Biology, EarlyView.
We distributed a survey to global institutions housing bush dogs (Speothos venaticus) to collect data on factors which may affect litter survival. Information from the Zoological Information Management System (ZIMS) and studbook records supplemented this dataset. We found that within northern temperate regions, the number of pups reared to the age of 1

Hormad1 mutation disrupts synaptonemal complex formation, recombination, and chromosome segregation in mammalian meiosis [PDF]

, 2010
Meiosis is unique to germ cells and essential for reproduction. During the first meiotic division, homologous chromosomes pair, recombine, and form chiasmata.

Kisspeptin as a test of hypothalamic dysfunction in pubertal and reproductive disorders

Andrology, EarlyView.
Abstract The hypothalamic–pituitary–gonadal axis is regulated by the gonadotropin‐releasing hormone pulse generator in the hypothalamus. This is comprised of neurons that secrete kisspeptin in a pulsatile manner to stimulate the release of GnRH, and, in turn, downstream gonadotropins from the pituitary gland, and subsequently sex steroids and ...

A pilot study on transcriptome data analysis of folliculogenesis in pigs

Animal, 2009
Three different stages of pig antral follicles have been studied in a granulosa-cell transcriptome analysis on nylon microarrays (1152 clones). The data have been generated from seven RNA follicle pools and several technical replicates were made.

Lifestyle Management in Menopause: A Systematic Review of Women With Premature Ovarian Insufficiency

Clinical Endocrinology, EarlyView.
ABSTRACT Objective Premature ovarian insufficiency (POI), the loss of ovarian function before age 40, increases the risk of cardiovascular disease, low bone mineral density, dementia and psychological distress. Lifestyle interventions reduce chronic disease risk in other populations and, with hormone therapy, may improve health outcomes in POI.
