The impact of transgenic IGF-IR overexpression on mammary development and tumorigenesis.

Abstract:

:Insulin-like growth factor-I and -II (IGF-I and IGF-II) and/or the type I insulin-like growth factor receptor (IGF-IR) have been implicated in a number of human tumors including breast cancer. However, despite being implicated in breast cancer for approximately 25 years and given that transgenic technology has been available for about the same period of time, it is surprising that transgenic mice overexpressing the IGF-IR in the mammary gland have only recently been characterized. This review will describe the effects of IGF-IR overexpression on mammary ductal morphogenesis and mammary tumorigenesis in the two available transgenic models.
