The mammalian genetic stress response
Advances in Enzyme Regulation
|January 1, 1986
Abstract:
A number of carcinogenic and cocarcinogenic agents induce new gene products in mammalian cells including primary human skin fibroblasts. These have been defined by cDNA cloning techniques, by protein resolutions in 2D PAGE and by the detection of new enzymatic functions. The uniform and transient genetic reaction is tentatively called the genetic stress response.
Insights
Carcinogenic agents trigger new gene products in human cells, a response identified through genetic and protein analysis. This transient genetic stress response is observed in mammalian cells, including skin fibroblasts.
Area of Science:
- Molecular biology
- Cellular biology
- Carcinogenesis research
Background:
- Carcinogenic and cocarcinogenic agents are known to alter cellular processes.
- Understanding cellular responses to carcinogens is crucial for cancer research.
Purpose of the Study:
- To identify and characterize new gene products induced by carcinogenic agents in mammalian cells.
- To define the nature of the uniform and transient genetic reaction observed.
Main Methods:
- cDNA cloning techniques were employed to identify new gene products.
- Two-dimensional polyacrylamide gel electrophoresis (2D PAGE) was used for protein resolution.
- Detection of novel enzymatic functions was performed.
Main Results:
- New gene products were successfully identified in mammalian cells, including primary human skin fibroblasts.
- Protein analysis via 2D PAGE revealed distinct changes.
- New enzymatic functions associated with these gene products were detected.
Conclusions:
- A uniform and transient genetic reaction, termed the genetic stress response, is induced by carcinogenic agents.
- This response involves the induction of specific new gene products and enzymatic functions.
- The findings contribute to understanding cellular defense mechanisms against carcinogens.
