title: A second trefoil protein, ITF/hP1.B, is transcribed in human breast cancer.
abstract: Trefoil proteins form a specific group of stable secreted polypeptides. They are expressed in a lot of human cancers and during inflammatory processes of the gastrointestinal tract. Recently a new human trefoil protein, ITF/hP1.B, was isolated. Until now no studies of the activity of this gene in human solid tumors exist. In our examination we show for the first time that this gene is transcribed in human breast cancer. In contrast to another trefoil protein, pS2, the expression of ITF/hP1.B is not under control of estrogen in the human breast cancer cell line MCF-7. We suggest that the gene activity of ITF/hP1.B in addition to pS2 expression may be an improved prognostic marker in human breast cancer.
