Steroidogenic compensation and lipid deficiency with enhanced NAD+ salvage in small‐for‐gestational‐age placenta

The FEBS Journal, EarlyView.
Fetal growth restriction is associated with placental metabolic adaptations. In small‐for‐gestational‐age placenta (SGA), cholesterol receptors and steroidogenic enzymes are upregulated, enhancing steroidogenesis. NAD salvage pathway is also increased to support NADP+/NADPH requirements.

Filamin A in the ovary: a mediator of granulosa cell functions

Reproduction and Fertility
Filamin A (FLNA) regulates the mechanical properties and shape of cells by cross-linking actin filaments orthogonally. It also serves as a scaffold for numerous interacting proteins, thereby coordinating cell differentiation and morphogenesis.

Corticotropin receptors, cyclic AMP and steroidogenesis

, 1984
The detection and characterization of the physiologically relevant receptors for corticotropin (ACTH) in rat adrenocortical cells is described. By the use of a radioligand with full biological potency and high specific radioactivity (1800+75 Ci/mmol), a ...

From hepatic to hematopoietic: LRH‐1's expanding cellular repertoire to the immune system

The FEBS Journal, EarlyView.
The nuclear receptor LRH‐1 is a well‐characterized regulator of endodermal tissue. Yet, increasing evidence indicates that LRH‐1, although expressed at low levels, is also a critical regulator of the hematopoietic system. LRH‐1 regulates the immune system by contributing to immune cell‐specific functions.

Serum Starvation Affects the Transcriptomic and Proliferative Response to ACTH in Primary Cultures of Rat Adrenocortical Cells

Cells
The adrenocorticotropic hormone (ACTH) is a key regulator of adrenal cortex function, promoting glucocorticoid synthesis and modulating cell proliferation.

Endocrine Disrupters, Steroidogenesis and Inflammation

, 2007
During the past decade, considerable information concerning the effects of endocrine disrupters (EDCs) on animals and humans has been accumulated. These compounds of anthropogenic or natural origin mimic the action of sex hormones, thus disturbing the ...

Genetic Parameters and Genome‐Wide Association Studies for Fertility and Reproduction Traits in U.S. Katahdin Sheep Based on the Single‐Step GBLUP Methodology

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Sheep production contributes to a secure and diverse food and fibre supply in the United States, with growing ethnic diversity strengthening demand. Katahdin is a composite hair‐type sheep breed developed in the United States that has become the most popular breed in many regions of the country and the first one to have genomic selection ...

Steroidogenesis and its control in rat corpus luteum [PDF]

, 1978
The rat corpus luteum produces progesterone which is essential for the maintenance of pregnancy. This steroidogenesis is influenced and maintained by 'the pituitary trophic hormone luteinising hormone.

Dietary L‐Tyrosine Sustains Egg Production and Quality by Modulating Promoter CpG Methylation, Gene Expression, and Hormone Profiles in Reproductive Signalling Pathways of Aged Laying Hens

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Managing prolactin (PRL)‐mediated reproductive suppression is critical for maintaining egg production in commercial laying hens. L‐tyrosine (TYR), a precursor of dopamine (DA), may counteract age‐related reproductive decline by suppressing PRL, thereby sustaining productivity and egg quality in late‐phase laying hens.
