The Wilms

Area of Science:

  • Molecular Biology
  • Developmental Biology
  • Genetics

Background:

  • The Wilms' tumour gene (WT1) encodes a protein with four zinc fingers, likely functioning as a transcription factor.
  • WT1 mutations in humans are associated with childhood kidney tumors and developmental defects in kidneys and gonads.
  • WT1 may play a role in the mesenchyme-to-epithelial transition in various mesodermally derived tissues.

Purpose of the Study:

  • To investigate the role of the WT1 gene and its protein product in embryonic development.
  • To explore the potential of WT1 as a tumor suppressor gene with a specific developmental function.

Main Methods:

  • Analysis of WT1 gene mutations and their correlation with developmental defects.
  • Investigation of WT1 protein's transcriptional regulatory activity.

Related Experiment Videos

  • Study of WT1's potential targets, including growth-factor genes.

    • Main Results:

    • WT1 mutations lead to significant developmental abnormalities in kidney and gonad formation.
    • WT1 protein appears to regulate the expression of growth-factor genes during development.
    • WT1 demonstrates a crucial role in the differentiation of mesodermal tissues.

    Conclusions:

    • The WT1 gene is essential for normal kidney and gonad development.
    • WT1 acts as a transcription factor, repressing growth-factor genes during development.
    • WT1 represents a novel class of tumor-suppressor genes with critical developmental functions.
