p63 overexpression induces the expression of Sonic Hedgehog.

p63 and p73 are members of the p53 protein family and have been shown to play an important role in cell death, development, and tumorigenesis. In particular, p63 has been shown to be involved in the maintenance of epidermal stem cells and in the stratification of the epidermis. Sonic Hedgehog (Shh) is a morphogen that has also been implicated to play a role in epithelial stem cell proliferation and in the development of organs.

Genotypic analysis of the TGF beta-509 allele in patients with systemic lupus erythematosus and Sjogren's syndrome.

Transforming growth factor beta (TGFbeta) is a secreted protein present in the circulation and is a critical regulator of the body's immune system. TGFbeta is believed to control several components of the immune system and inhibit autoimmune reactions. Systemic lupus erythematosus (SLE) and Sjogren's syndrome (SS) are prototypical human autoimmune diseases characterized by the circulating autoantibodies directed against nuclear antigens and immune complex deposition in various tissues leading to target organ inflammation and damage.
