The D(3) dopamine receptor inhibits dopamine release in PC-12/hD3 cells by autoreceptor signaling via PP-2B, CK1, and Cdk-5.

7 Jun 2009 The function of the D(3) dopamine (DA) receptor remains ambiguous largely because of the lack of selective D(3) receptor ligands. To investigate the function and intracellular signaling of D(3) receptors, we established a PC-12/hD3 clone, which ... Read more...

Effect of NH4+ and glycerol on cytidine 5'-diphosphocholine synthesis in Saccharomyces cerevisiae.

18 May 2009 Both stimulation of ammonium ion on the glycolytic flux and regulation by glycerol of enzymes in Kennedy pathway for cytidine diphosphate choline production in S. cerevisiae were studied. The conventional transformation course featured four stages. ... Read more...

Myoblast sensitivity and fibroblast insensitivity to osteogenic conversion by BMP-2 correlates with the expression of Bmpr-1a.

13 May 2009 BACKGROUND: Osteoblasts are considered to primarily arise from osseous progenitors within the periosteum or bone marrow. We have speculated that cells from local soft tissues may also take on an osteogenic phenotype. Myoblasts are known to adopt a ... Read more...

Technical information about 'Feedback, Biochemical'

Definition: A mechanism of communication among life processes to coordinate development, reproduction, and homeostasis. In humans, feedback loops are especially important for communication between organs that are spatially separated. Virtually all hormones from the nervous and endocrine systems are under feedback control: by peripheral hormones, cations, metabolites, osmolarity or extracellular fluid volume.
