In this line, in oral squamous cell carcinoma collagen XVI expression is induced which results in an upregulation of Kindlin-1 followed by an increased interaction with beta1-integrin.
Loss of function mutations in the FERMT1 gene which encodes Kindlin-1 leads to the development of Kindler Syndrome (KS) an autosomal recessive skin disorder characterized by skin blistering, photosensitivity, and predisposition to aggressive squamous cell carcinoma (SCC).
These latter findings support a tumor suppressor function for KIND1, and identify c-Jun N-terminal kinase and NF-κB as potential therapeutic targets for prevention of squamous cell carcinoma in patients with Kindler syndrome.
