Pretreatment anti-Müllerian hormone predicts for loss of ovarian function after chemotherapy for early breast cancer [PDF]

, 2013
Aim: Improving survival for women with early breast cancer (eBC) requires greater attention to the consequences of treatment, including risk to ovarian function. We have assessed whether biochemical markers of the ovarian reserve might improve prediction

The Role of miRNAs in Chicken Immune Regulation and Prospects for Disease‐Resistant Breeding

Animal Research and One Health, EarlyView.
A schematic workflow illustrating the screening of disease‐resistant miRNAs and the generation of miRNA‐based disease‐resistant chickens via PGC‐mediated germline genome editing. ABSTRACT MicroRNAs (miRNAs) are emerging as pivotal regulators of the immune system, playing a decisive role in shaping disease resistance in chicken.

Theca: the forgotten cell of the ovarian follicle [PDF]

Reproduction, 2010
Abstract Theca cells function in a diverse range of necessary roles during folliculogenesis; to synthesize androgens, provide crosstalk with granulosa cells and oocytes during development, and provide structural support of the growing follicle as it progresses through the developmental stages to produce a mature and fertilizable ...

Genomic Structural Variations Provide Insights Into Litter Size and Teat Number Traits in Hu Sheep

Animal Research and One Health, EarlyView.
Here, we conducted whole genome sequencing on 300 Hu sheep with an average depth of 16.51X. Two candidate genes associated with litter size and teat number traits were identified, namely MAST2 and AFDN. ABSTRACT Litter size and the teat number are important economic indicators in sheep production.

Correlation between basal antral follicle count and mean ovarian diameter with ovarian responsiveness in art cycles

Majallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Bābul, 2006
BACKGROUND & OBJECTIVE: Since, ovarian response during assisted reproductive technology (ART) depends on ovarian reserve so it is important to evaluate ovarian reserve before the ART cycle.

Ovarian follicle burnout: A universal phenomenon? [PDF]

Cell 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.

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.

Is in utero exposure to maternal socioeconomic disadvantage related to offspring ovarian reserve in adulthood?

Women's Midlife Health, 2018
Background Because the ovarian follicle pool is established in utero, adverse exposures during this period may be especially impactful on the size and health of the initial follicle endowment, potentially shaping trajectories of ovarian follicle loss and

The relation between variation in size of the primordial follicle pool and age at natural menopause

, 2015
Context: Tumors producing insulin-like growth factor 2 (IGF-2oma) are a major cause of spontaneous hypoglycemia. The treatment mainstay is surgical resection.
