Summary
Maspin (SERPINB5), a tumor suppressor, is crucial for regulating cell adhesion and invasion. This review details mouse models used to study maspin
Area of Science:
- Cellular biology
- Molecular oncology
- Tumor suppressor genes
Background:
- Clade B serpin family proteins regulate cellular functions like adhesion and motility.
- Maspin (SERPINB5) is a key clade B serpin and a type II tumor suppressor.
- Maspin expression decreases in breast tumors, correlating with invasiveness.
Purpose of the Study:
- To review the development of mouse models for studying maspin's role in mammary tumorigenesis.
- To investigate maspin's function in normal mammary development in vivo.
- To validate in vitro findings on maspin's regulation of apoptosis, adhesion, migration, and invasion.
Main Methods:
- Development of transgenic mouse models.
- Utilization of syngeneic mouse models.
- In vivo studies of mammary gland development and tumorigenesis.
Main Results:
- Maspin's role in regulating cell apoptosis, adhesion, migration, and invasion is studied in vivo.
- Transgenic and syngeneic models allow for the investigation of maspin's impact on mammary development.
- These models are essential for verifying cell culture observations in a living system.
Conclusions:
- Mouse models are critical for understanding maspin's in vivo functions in mammary biology.
- Studying maspin in these models will elucidate its role as a tumor suppressor.
- Further research using these models will advance knowledge of mammary tumorigenesis and development.

Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...
