The raw material for the recalled heparin batches was processed in China from pig's intestines by the American pharmaceutical firm Scientific Protein Laboratories. [1] [2] [3] The U.S. Food and Drug Administration was quoted as stating that at least 81 deaths were believed to be linked to a raw heparin ingredient imported from the People's Republic of China, and that they had also received 785 ...
Heparin-binding EGF-like growth factor has been shown to interact with NRD1, [9] Zinc finger and BTB domain-containing protein 16 [10] [11] and BAG1. [12]HB-EGF biological activities with these genes influence cell cycle progression, molecular chaperone regulation, cell survival, cellular functions, adhesion, and mediation of cell migration.
Overexpression of FGF9 in prostate epithelial cells can lead to high grade prostate intraepithelial neoplasia, which is a precursor for prostate cancer. Additionally, high expression of the gene in prostate epithelial cells disrupts prostate tissue homeostasis, and promotes a high frequency of metastasis.
Structure formula of one of the many sulfation patterns of the heparan sulfate subunit. Heparan sulfate (HS) is a linear polysaccharide found in all animal tissues. [1] It occurs in a proteoglycan (HSPG, i.e. Heparan Sulfate ProteoGlycan) in which two or three HS chains are attached in close proximity to cell surface or extracellular matrix proteins.
Heparin, also known as unfractionated heparin (UFH), is a medication and naturally occurring glycosaminoglycan. [3] [4] Heparin is a blood anticoagulant that increases the activity of antithrombin. [5] It is used in the treatment of heart attacks and unstable angina. [3] It can be given intravenously or by injection under the skin. [3]
Perlecan is a key component of the extracellular matrix of cartilage [15] where it is essential for normal growth plate development and long bone growth. [16] [17] The dwarfism exhibited by the perlecan null mouse resembles the phenotype produced by activating mutations in the gene for FGFR3, [18] a receptor for fibroblast growth factors.
In cell biology, precursor cells—also called blast cells—are partially differentiated, or intermediate, and are sometimes referred to as progenitor cells. A precursor cell is a stem cell with the capacity to differentiate into only one cell type, meaning they are unipotent stem cells .
Simplification on the mutation 46 XX 4q16.3 (female), 46XY 4q16.3 (male). Gain of function mutations in this gene can develop dysfunctional proteins "impede cartilage growth and development and affect chondrocyte proliferation and calcification" [6] which can lead to craniosynostosis and multiple types of skeletal dysplasia (osteochondrodysplasia).
