Abstract
The present invention relates to transgenic animals, as well as compositions and methods relating to the characterization of gene function. Specifically, the present invention provides transgenic mice comprising mutations in a BMP gene. Such transgenic mice are useful as models for disease and for identifying agents that modulate gene expression and gene function, and as potential treatments for various disease states and disease conditions.
Claims4
A transgenic mouse whose genome comprises a disruption in an endogenous BMP gene comprising the nucleic acid sequence set forth in SEQ ID NO:
- 1, wherein where the disruption is homozygous, the transgenic mouse lacks production of functional protein encoded by the nucleic acid sequence, and exhibits at least one of the following phenotypes:
- a kinky tail, low body weight or short body length, relative to a wild-type mouse.
A transgenic mouse comprising a heterozygous disruption in an endogenous BMP gene comprising the nucleic acid sequence set forth in SEQ ID NO:
- 1, wherein the disruption in a homozygous state results in lack of production of functional protein encoded by the nucleic acid sequence;
- and a transgenic mouse exhibiting at least one of the following phenotypes:
- a kinky tail, low body weight or short body length, relative to a wild-type mouse.
A method of producing a transgenic mouse comprising a disruption in an endogenous BMIP gene comprising the nucleic acid sequence set forth in SEQ ID NO:
- 1, the method comprising:
- a) introducing a targeting construct capable of disrupting the endogenous BMP gene comprising the nucleotide sequence set forth in SEQ ID NO:
- 1 into a murine embryonic stem cell;
- b) selecting a murine embryonic stem cell that has undergone homologous recombination;
- (c) introducing the murine embryonic stem cell into a blastocyst;
- (d) implanting the resulting blastocyst into a pseudopregnant mouse, wherein said mouse gives birth to a chimeric mouse;
- and
- (e) breeding the chimeric mouse to produce the transgenic mouse, wherein where the disruption is homozygous, the transgenic mouse lacks production of functional protein encoded by the nucleic acid sequence set forth in SEQ ID NO:
- 1, and exhibits at least one of the following phenotypes:
- a kinky tail, low body weight or short body length, relative to a wild-type mouse.
