GSE60569: Sustained expression of activated beta-catenin in dermal fibroblasts causes skin fibrosis

• Organsim mouse
• Type RNASEQ
• Target gene
• Project ARCHS4

Forced expression of activated beta-catenin in mouse dermal fibroblasts is sufficient to cause spontaneous, progressive skin fibrosis in vivo. We generated triple-transgenic HoxB6CreERT/+; R26-YFP/+; Catnbex3/+ "activated beta-catenin" mice and double-transgenic HoxB6CreERT/+; R26-YFP/+ littermate control mice. We induced Cre activity (resulting in expression of activated beta-catenin in triple-transgenic mutant fetuses) by administering tamoxifen to the pregnant dam at embryonic day 16.5. The activated beta-catenin mice developed fibrotic skin, characterized by elevated collagen deposition and increased fibroblast proliferation. We performed RNA-sequencing to profile gene expression in the dermis of control and activated beta-catenin mutant mice with established skin fibrosis at 3 weeks of age.
