Receptor-mediated endocytosis of tissue-type plasminogen activator by the human hepatoma cell line Hep G2.
Receptor-mediated endocytosis of tissue-type plasminogen activator (t-PA) was characterized with the human hepatoma cell line Hep G2. At 4 degrees C binding of 125I-t-PA to Hep G2 cells is rapid, specific, saturable, and reflective of a homogeneous population of 76,000 high-affinity surface sites per cell (Kd = 3.7 nM). The kinetics of 125I-t-PA binding to its receptor are characterized by rate...
متن کامل25-Hydroxylation of vitamin D3 in the human hepatoma cell lines Hep G2 and Hep 3B.
Two human hepatoma cell lines, Hep G2 and Hep 3B, were screened for vitamin D3-25-hydroxylase enzyme activity by incubation with radioactive vitamin D3. A compound co-chromatographing with 25-OH-D3 was synthesized in both cell lines but its rate of synthesis was tenfold greater in Hep 3B than in Hep G2 cells. The identity of the compound was confirmed by comparing its chromatographic properties...
متن کاملParameters of cholesterol metabolism in the human hepatoma cell line, Hep-G2.
The human hepatoma cell line Hep-G2 has been shown to express the major enzymes of intra- and extracellular cholesterol metabolism. These include lecithin:cholesterol acyltransferase, acyl coenzyme A:cholesterol acyltransferase, 3-hydroxy-3-methylglutaryl coenzyme A reductase, and cholesterol-7 alpha-hydroxylase. Regulatory mechanisms that have been described in other hepatic systems also appea...
متن کاملCYTOKINE AND GROWTH FACTOR MODULATION OF CELL CYCLE EVENTS IN HUMAN MELANOMA CELL LINES
Cytokines influence cell cycle events, which in some but not all instances can be associated with melanoma progression. Analysis of the G0/G 1 and S phase fractions of the cell cycle was used to assay the proliferative or inhibitory activity of cytokines against ten human melanoma cell lines, including pairs of cell lines derived from primary and metastatic tissue of individual patients. Cy...
متن کاملHeterogeneity of nascent high density lipoproteins secreted by the hepatoma-derived cell line, Hep G2.
Nondenaturing gradient gel analysis of high density lipoproteins (HDL, d 1.063-1.235 g/ml) isolated from Hep G2 24-hr, serum-free conditioned media shows four distinct, reproducible particle subclasses I, II, III, and IV with apparent Stokes' diameters of 13.3, 12.0, 9.5, and 7.4 nm, respectively. Fractions enriched in lipoproteins from each of these subclasses were isolated by either density g...
