Epidermal growth factor,

      Epidermal growth factor is the body of an active substance, consisting of 53 amino living cells, by stimulating epidermal growth factor receptor tyrosine phosphorylation, the skin surface cells to repair hyperplasia, is said to injuries,the loss of the epidermis has an excellent efficacy. Its greatest feature is able to promote cell proliferation and differentiation of new cells to replace the aging and dying cells. EGF can stop bleeding and accelerate the skin and mucosal wound healing, anti-inflammatory... [Lire la suite]

Growth factors and hormones

    Variety of hormones, growth factors have an important role for maintaining cell function to maintain cell state (differentiated or undifferentiated). Some hormonal growth promoting effect on many cell growth, such as insulin, which promote cell use of glucose and amino acids. A certain type of cells, some hormones role, such as hydrocortisone can promote the growth of epidermal cells, prolactin to promote mammary epithelial cell growth.

Epidermal growth factor (EGF) found

      In 1962, Dr. Cohen accidentally discovered in an experiment of epidermal growth factor (EGF), it is a widely present in the small molecule peptide or other animals, a very low concentration, can strongly stimulate cell growth, inhibit the aging gene appears, slow down the aging epidermal cells. Combining with its receptor play a role.       Epidermal growth factor receptor (EGFR) is a tyrosine kinase activity of the membrane surface receptors, intracellular District 3 sub-region is to play the key...

lecular structure of the epidermal growth factor (EGF)

    EGF is by 53 amino acid residues of a peptide, molecular weight for 6045 D. The earliest EGF is 1962 years from mouse contents extract to extract a thermal stability of material, since it has induced eyelids open and mice early early out the role of long teeth and was named the epidermal growth factor. EGF is through the cell membrane and the epidermal growth factor receptor (EGFR) combined with and play their role. EGFR is a exists in the surface of cells across the membrane protein molecules multi-function,... [Lire la suite]

The epidermal growth factor family profile

    The epidermal growth factor family (epidermal growthfac-tor family) is a group of and epidermal growth factor (EGF epidermal growthfactor) structure and the biological function of close glycoprotein, it consists of EGF, transformation growth factor (transform-ing growthfactor, TGF), heparin combination EGF sample growth factor   (heparin-binding EGF-likegrowth factor,HB-EGF),gender regulatory protein(amphiregulin,AR),cellularregulation element(betacellulin,BTC),epiregulin,NDFs (neudifferentiationfactors), a growth...

The clinical significance of HERZ

Excessive expression of lung cancer on radiation therapy HERZ not sensitive to the chemotherapy drug resistant, and with monoclonal antibodies for HERZ significantly inhibit excessive express HERZ of lung cancer cell lines, and can increase the sensitivity of the cancer cells to chemotherapy. In addition, HERZ had breast cancer patients to express), agents may resistance, the endocrine therapy effect is poor, the onion rings drugs is better than the adjuvant chemotherapy), agents (CMF, beauty of hebron method). HERZ had expressed... [Lire la suite]
