Insights

Transgenic models reveal matrix metalloproteinases (MMPs) directly impact lung emphysema and inflammatory cell recruitment. This technology enables controlled experiments in mammals to study MMP roles in disease.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Genetics

Background:

  • Matrix metalloproteinases (MMPs) are crucial proteinases involved in numerous physiological and pathological processes.
  • Understanding the direct role of MMPs in disease pathogenesis is essential for developing targeted therapies.

Purpose of the Study:

  • To investigate the direct contribution of MMPs to physiological and pathological processes using transgenic technology.
  • To explore MMP-dependent mechanisms in disease development and inflammatory responses.

Main Methods:

  • Utilizing gain of function and loss of function transgenic models in mammals.
  • Performing controlled experiments to elucidate the causative roles of MMPs.

Main Results:

  • Confirmed causative roles of specific MMPs in the development of pulmonary emphysema.
  • Uncovered a novel MMP-dependent mechanism regulating inflammatory cell recruitment.

Conclusions:

  • Transgenic technology provides powerful tools for dissecting MMP functions in complex mammalian systems.
  • Controlled experiments in vivo are crucial for validating the roles of MMPs in disease and inflammation.

In-vitro Mutagenesis

To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.

Mouse Models of Cancer Study

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,...

Role of Matrix Metalloproteases in Degradation of ECM

Matrix metalloproteases (MMPs) are enzymes involved in the hydrolysis of proteins and glycoproteins of the extracellular matrix. MMPs are essential for the migration and proliferation of cells through the dense matrix network, throughout embryonic development, and throughout morphogenesis. The first MMP activity discovered was a collagenase in a tadpole's tail undergoing metamorphosis. The active collagen deposition and modifications lead to the morphogenesis of tadpoles into the adult body.
