1. The mechanism of integrin inactivation and cell signalling induced by c-erbB2, an oncogenic growth factor receptor
Abstract : Overexpression of the oncogenic growth factor receptor, c-erbB2, is linked with poor prognosis in breast carcinomas and is used as a target for therapeutic strategies. To elucidate the mechanism underlying the tumorigenic action of an elevated c-erbB2 level, leading to homodimerization and activation, we have used an inducible system where a hybrid receptor consisting of the cytoplasmic and transmembrane domains of c-erbB2 fused to the extracellular domain of the trkA NGF receptor has been stably transfected into an immortalized mammary epithelial cell line.

2. Molecular factors influencing epithelial-mesenchymal transition in breast cancer
Abstract : Epithelial-mesenchymal transition (EMT) is a developmental process defined by loss of epithelial characteristics and acquisition of mesenchymal phenotype. EMT or similar processes are also implicated in carcinoma cell invasion and the progression of breast carcinoma to metastasis. READ MORE

4. Molecular and cytogenic studies of oncogene alterations in human breast and cervical carcinomas
Abstract : Characterization of human tumors with associated genetic changes is of importance for better understanding the tumor's basic biological behavior and of great value for clinical management of cancer patients. We therefore investigated oncogene amplifications in human breast and cervical carcinomas using molecular and cytogenetic methods, especially FISH. READ MORE
