Contributor Information
- Name Fiona Watt
- Institute Cancer Research UK, London Research Institute: Lincoln's Inn Fields
Tool Details
- Tool name: K14dNLef1 Mouse
- Tool type: Experimental models
- Tool sub-type: Mouse
- Cancer type: Sebaceous adenoma; Sebeoma; Squamous papilloma
- Disease: Cancer; Sebaceous adenoma; Sebeoma; Squamous papilloma; Telogen effluvium;
- Conditional: Yes
- Conditional description: Conditional expression of deltaN-Lef1 under Keratin 14 promoter giving tissue-specific epidermal expression.
- Genetic background and cross history: A deltaNLef1 transgene vector, containing an N-terminally deleted mouse Lef1 cDNA under the control of the keratin 14 promoter, was injected into fertilised CBA/C57BL6 ooctyes. Founders were backcrossed to establish transgenic lines.
- Phenotype: Tumourigenesis (skin); skin abnormalities (hair follicle, sebaceous gland)
- Zygosity:
- Description: In vivo study of Lef1 activity in skin; model for hair growth & follicle formation; disease model for skin tumour formation (sebaceous adenoma, sebeoma, squamous papilloma)
- Research area: Cancer; Cell Signaling & Signal Transduction; Developmental Biology; Epigenetics & Nuclear Signalling; Genetic studies; Stem Cell Biology
- Production details: A deltaNLef1 transgene vector, containing an N-terminally deleted mouse Lef1 cDNA under the control of the keratin 14 promoter, was injected into fertilised CBA/C57BL6 ooctyes. Founders were backcrossed to establish transgenic lines.
