Deregulated c-fos expression interferes with normal bone development in transgenic mice
Nature
|January 4, 1987
Abstract:
Transgenic mice were generated expressing c-fos genes under the control of the human metallothionein promoter. Although high levels of c-fos messenger RNA were detectable in a variety of tissues, deregulated c-fos expression specifically interfered with normal bone development without inducing malignant tumours.
Insights
Researchers created transgenic mice with deregulated c-fos gene expression. This altered bone development but did not cause cancerous tumors, highlighting c-fos
Area of Science:
- Molecular Biology
- Genetics
- Developmental Biology
Background:
- The c-fos gene is an immediate-early gene involved in cellular responses.
- Understanding c-fos regulation is crucial for studying development and disease.
Purpose of the Study:
- To investigate the effects of deregulated c-fos gene expression in vivo.
- To determine if altered c-fos levels impact specific physiological processes, such as bone development.
Main Methods:
- Generation of transgenic mice utilizing the human metallothionein promoter to drive c-fos expression.
- Detection of c-fos messenger RNA (mRNA) levels across various tissues.
Main Results:
- High levels of c-fos mRNA were observed in multiple tissues of the transgenic mice.
- Specific interference with normal bone development was noted.
- No induction of malignant tumors was observed despite high c-fos expression.
Conclusions:
- Deregulated c-fos expression can specifically disrupt bone development.
- High levels of c-fos expression, under these conditions, do not necessarily lead to tumorigenesis.
