Defining Live Cell Liver Peptide Growth Factors
From the Department of Pathology and Laboratory Medicine at Brown University in Providence, Rhode Island, U.S.A., three investigating pathologists, Drs. N. Fausto, A.D. Laird, and E.M. Webber, advise: "During liver regeneration quiescent hepatocytes [liver cells] undergo one or two rounds of replication and then return to a nonproliferative state. Growth factors regulate this process by providing both stimulatory and inhibitory signals for cell proliferation.”
The idea of intrinsic hepatic growth control factors produced by animal and human liver cells has been stated in published reports, which date back as Iong as forty-six years ago. Much of this early research was conducted on rats and dogs, but currently clinical investigations among both healthy human volunteers and really sick people have taken place.
Comprised of the tiniest of protein molecules which biochemists and physiologists call peptides, these growth factors are of an exceedingly low molecular weight (30,000 Da) which yield two or more amino acids on hydrolysis. The Dalton with a symbol of D or Da, also called an atomic mass unit is equivalent to 1.657 X 10 (24) gm. Peptide growth factors form by loss of water from the NH2and COOH molecular groups of adjacent amino acids and are additionally referred to in biochemistry as di-, tri-, tetra-, etc. peptides, depending on the number of amino acids in the molecule. Thus peptides make up the constituent parts of proteins. Examples of those several dozen peptides from the human liver and other organs which often give birth to growth factors are: hepatocyte growth factor (HGF), epidermal growth factor (EGF), transforming growth factor-beta (TGF-beta), and dozens more. |
