Development and Characterization of Transgenic Mice with Mammary Gland Specific Expression of the Tumor Suppressor
Abstract
Tumor suppressor MMACl/PTEN/TEPl is considered related with breast cancer formation or progression due to a collective evidence of mutant MMAC 1 in various advanced cancers, especially breast carcinoma. Our preliminary data as well as results of most recent study have provided further evidence of MMAC 1 regulation on PI3K pathway signaling and cell activities, such as cell growth and survival. Our observation of differential modulation of MMAC1 on protein tyrosine phosphorylation in cells indicates a complex role of MMAC1 in multiple cell signals. Thus, the established MMAC 1 transgenic mice model will undoubtedly help to determine the role of MMACl in mammary development and tumorigenesis in vivo.
