The tight skin 2 mouse

Abstract

Tsk2 is a novel mutation which displays histopathologic and biochemical abnormalities similar to those present in the skin of patients with SSc, including increased collagen content and expression of type I collagen genes. This mutation has been mapped to a 15.3-cM region on mouse chromosome 1. Further study of this novel mutation will allow the identification of previously undescribed mechanisms involved in the regulation of normal and pathologic collagen gene expression.
