Amphiregulin, also known as AREG, is a protein that in humans is encoded by the AREG gene.[5][6][7]

Function[edit]

The protein encoded by this gene is a member of the epidermal growth factor (EGF) family.[5]

It is an autocrine growth factor as well as a mitogen for astrocytes, Schwann cells, fibroblasts. It is related to epidermal growth factor (EGF) and transforming growth factor alpha (TGF-alpha). This protein interacts with the Epidermal growth factor receptor (EGFR) to promote the growth of normal epithelial cells.

Biological role[edit]

Estradiol and progesterone mostly induce amphiregulin expression to mediate ductal development of the mammary glands.[8][9][10][11][12] Amphiregulin has been found to be essential for mammary ductal development, as evidenced by absence of ductal growth in amphiregulin knockout mice.[11] This is similar to the phenotypes of EGFR and ERα knockout mice, which also show absence of ductal growth.[11]

Clinical significance[edit]

Mutations in this encoded protein are associated with a psoriasis-like skin phenotype.[5] Higher circulating levels of amphiregulin are associated with AGVHD progression. [13]
