In this short overview of oncogenes and cell growth, the protein products have been divided into two classes, proto-oncogenes and oncogenes. Proto-oncogenes can be activated by point mutations and deletions. Two classes exist: the dominant, which leads to cell growth and the suppressor, which by definition suppresses growth.

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.

Current Protocols in Immunology, 1997
AbstractThis appendix provides two protocols for monitoring cell growth. Counting cells using a hemacytometer is tedious but it allows one to effectively distinguish live cells from dead cells (using Trypan Blue exclusion). In addition, this procedure is less subject to errors due to cell clumping or heterogeneity of cell size. The use of an electronic

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.

Cell-to-Cell Communication and the Control of Growth
American Review of Respiratory Disease, 1990Growth of transformed cells is inhibited by cell-to-cell communication with normal cells. This communication is regulated by certain oncogenes that alone or in cooperation can block the communication.

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.

Tumor cell growth and cell kinetics
Seminars in Oncology Nursing, 1992Cancer cells differ from normal cells in many ways, but most importantly by not responding to normal growth-control mechanisms. Whereas the growth and division of normal cells is carefully regulated to meet the needs of the body, tumor cells proliferate autonomously and continually, eventually interfering with and destroying the functions of normal ...

Journal of Biomedical Materials Research, 1993
AbstractA cell growth factor protein (insulin) and/or a cell‐adhesion protein (fibronectin) were immobilized on surface‐hydrolyzed poly(methyl methacrylate) membranes. The growth of mouse fibroblast cells STO was accelerated by the immobilized insulin. This acceleration was enhanced by introduction of spacer arms.
