CDK4-Transformed Mouse Podocytes Useful for Studying Glomerular Diseases

Posted Jul 26 2011 8:00pm

Description of Invention:
Podocytes, cells of the visceral epithelium in the kidneys, are a key component of the glomerular filtration barrier. Podocyte damage and loss contribute to the initiation of glomerular diseases. Cyclin-dependent kinase 4 (CDK4), a catalytic subunit of the cyclin D-CDK4 serine/threonine kinase complex, is a critical regulator of the cell cycle. Recent studies showed that cells immortalized with CDK4 are useful to study pathophysiology. NIH investigators have generated mouse podocytes transformed with CDK4 as a nonviral immortalizing gene. These transformed podocytes show podocyte characteristics and express podocyte markers. Furthermore, confluent CDK4-podocyte cultures show higher levels of gene expression for multiple podocyte differentiation genes compared with subconfluent or lower density culture.

  • Model system for study of glomerular disorders.
  • Useful tools to study podocyte biology.

Better model system to study podocyte structure and function.

Development Status:
  • Early-stage
  • Pre-clinical
