Corticosterone (CORT) can stimulate growth hormone (GH) cell (somatotroph) differentiation and GH secretion on embryonic day (e) 12 but not e20 in the chicken. GH induction involves both glucocorticoid receptors (GR) and ...

This study was designed to develop an in situ histochemical heme staining method for an intact animal using the free-living nematode Caenorhabditis elegans. Although, heme is vital to many biological processes and synthesized ...

Understanding the immune defense of the mammary gland is important in devising and developing measures to control mastitis. Lipopolysaccharide (LPS) is the predominant factor causing pathogenesis in Gram-negative bacterial ...

The secretion of fat droplets from mammary epithelial cells requires the expression of two major proteins, butyrophilin1A1 (BTN) and xanthine oxidoreductase (XOR). Ablation of the BTN or XOR gene in mice results in the ...

Short-term storage trials were conducted in 2008 and 2009 on Atlantic sturgeon semen obtained from captive males, held at the U.S. Fish and Wildlife Service, Northeast Fish Technology Center, that were hormonally induced ...

Lysine and arginine transport is primarily mediated by cationic amino acid transporters (CATs) in cells. The chicken CAT-2 (cCAT-2) transcript is alternatively spliced to three isoforms. Transcriptional and cellular ...

Despite its biological significance, little is known about how animals sense and respond to heme to maintain homeostasis. C. elegans is a heme auxotroph, which makes it an excellent model to identify and dissect heme ...

The neonatal Fc receptor for IgG (FcRn), a major histocompatibility complex (MHC) class I-related molecule, plays an important role in IgG transport and protection. The transport of IgG across epithelial and endothelial ...

Growth hormone (GH) effects growth and contributes to a lean phenotype in broiler chickens. GH secretion by the anterior pituitary begins on embryonic day (e) 14, concomitantly with a rise in adrenal glucocorticoids (GC) ...
