Researchers study mouse development by examining gene families like homeobox (Hox), paired-box (Pax), and POU genes. Analyzing these genes in mouse models reveals the genetic basis of developmental control.

Area of Science:

  • Developmental Biology
  • Genetics
  • Molecular Biology

Background:

  • Gene families such as homeobox (Hox), paired-box (Pax), and POU genes are crucial for regulating embryonic development.
  • Understanding these gene families' roles is key to deciphering developmental processes.

Purpose of the Study:

  • To compare gene organization, structure, and expression patterns of Hox, Pax, and POU gene families in mice.
  • To analyze the functions of these genes using molecular and genetic approaches.

Main Methods:

  • Comparative analysis of gene families based on homology to Drosophila and human transcription factors.
  • In vitro and in vivo functional analysis using mouse mutants and transgenic mice.
  • Generation of gain- or loss-of-function mutations via random or targeted transgene introduction.

Main Results:

  • Identification and characterization of key gene families involved in mouse development.
  • Elucidation of gene organization, structure, and expression patterns.
  • Demonstration of gene function through mutant and transgenic mouse models.

Conclusions:

  • Comparative genomics and functional studies of gene families provide insights into developmental regulation.
  • Mouse models are powerful tools for dissecting the genetic control of development.
  • These strategies reveal successive steps in genetic developmental control.
