Expression of ΔNLef1 in mouse epidermis results in differentiation of hair follicles into squamous epidermal cysts and formation of skin tumours

Abstract excerpt

To examine the consequences of repressing beta-catenin/Lef1 signalling in mouse epidermis, we expressed a DeltaNLef1 transgene, which lacks the beta-catenin binding site, under the control of the keratin 14 promoter. No skin abnormalities were detected before the first postnatal hair cycle. However, from 6 weeks of age, mice underwent progressive hair loss which correlated with the development of dermal cysts....
