CYTOKINE 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 کاملPlant Cell Growth and Elongation
The plant cell wall is a strong material that resists expansion when water is taken up by the protoplast; for cells to expand irreversibly, the existing wall architecture must be loosened to permit the insertion of newly synthesized wall polymers. Biochemical approaches have identified changes in wall composition that occur during growth and some of the enzymes involved in wall loosening, whils...
متن کاملPlant cell growth in tissue.
Cell walls are part of the apoplasm pathway that transports water, solutes, and nutrients to cells within plant tissue. Pressures within the apoplasm (cell walls and xylem) are often different from atmospheric pressure during expansive growth of plant cells in tissue. The previously established Augmented Growth Equations are modified to evaluate the turgor pressure, water uptake, and expansive ...
متن کاملExpansive growth of plant cell walls.
The enlargement of plant cell walls is a key determinant of plant morphogenesis. Current models of the cell wall are reviewed with respect to their ability to account for the mechanism of cell wall enlargement. The concept of primary and secondary wall loosening agents is presented, and the possible roles of expansins, xyloglucan endotransglycosylase, endo-1,4-beta-D-glucanase, and wall synthes...
متن کاملB Cell Growth Factor Distinct
The importance of murine monokines and lymphokines in T cell immune responses has been emphasized by the development o f T cell cloning technology (1) and the identification of cloned tumor lines that respond to or secrete these factors (2, 3). Such studies have shown that the monokine interleukin 1 (IL-1) 1 induces certain T cells to secrete interleukin 2 (IL-2), and that this lymphokine can m...
