Growth Factors and Regulation of Cell Growth
Annual Review of Medicine, 1982A new class of polypeptide hormones known collectively as growth factors has been identified. These polypeptides are able to stimulate DNA synthesis and mitosis of cells cultured in vitro. Growth factors have been isolated from several sources, including platelets, submaxillary glands, pituitary, brain, and medium conditioned by cells grown in vitro ...

Curcumin, the active ingredient of turmeric (Curcuma longa) used in culinary and medical practices in Asia, has immense potential for being used in cancer chemotherapy because of its control over the cell growth regulatory mechanisms. The present chapter throws light on the role of curcumin in modulating the various phases of the cell cycle and its ...

Cell length, cell growth and cell division
Nature, 1976When cells of E. coli reach a certain critical length, which is constant in all growth conditions and eqqal to twice the minimum cell length, they abruptly increase their rate of elongation and divide about 20 min later. Chromosome replication terminates at about this same cell length but is not the signal for the change in rate of cell elongation.

Coordination of cell growth with cell division
Current Opinion in Genetics & Development, 1999Proliferating cells must increase their mass coordinately with cell division. Recent evidence suggests that coupling of cell growth with cell division might be achieved by making synthesis of activators of cell division particularly sensitive to the capacity of the cell's protein synthesis machinery.

The coupling of cell growth to the cell cycle
Current Opinion in Cell Biology, 2001The development of a complex multicellular organism requires a coordination of growth and cell division under the control of patterning mechanisms. Studies in yeast have pioneered our understanding of the relationship between growth and cell division.

Growth control by cell to cell contact
Journal of Supramolecular Structure, 1979AbstractControl of cell growth by cell to cell contact is reviewed with particular emphasis on two systems – contact inhibition of growth observed with Swiss 3T3 cells and the mitogenic stimulation of Schwann cells by dorsal root ganglia neurites.

Phosphoinositides and Cell Growth
1992The findings described above illustrate how the src kinase can influence several new pathways of inositol phosphate metabolism, both at the membrane level with the production of novel D-3 phosphoinositides and the activation of PI-3 kinase, and at the cytosolic level by altering the expression of certain inositol polyphosphates, in particular Ins(1,4,5,

The Bulletin of Mathematical Biophysics, 1967
A theory of growth of a cell which takes up nutrients by diffusion or active transport is discussed. The main conclusion is that the volume should grow at least as fast as the third power of the time. Existing experimental evidence is not a conclusive test of the theory, and further experiments to test it are proposed.

Interferons in cell growth and development
Trends in Genetics, 1989Interferons (IFNs), besides inducing an antiviral state in uninfected cells, are also natural regulatory molecules. They play a key role in the regulation both of cell growth and differentiation, and of development. Up- or down-regulation of oncogenes by IFNs may be one of the mechanisms by which these molecules affect cell physiology.
