The erbB-2 receptor plays an important role in the prognosis of breast cancer and is expressed at high levels in nearly 30% of tumors in breast cancer patients. While evidence accumulates to support the relationship between erbB-2 overexpression and poor overall survival in human breast cancer, understanding of the biological consequence(s) of erbB-2(More)
The metastatic process requires changes in tumor cell adhesion properties, cell motility and remodeling of the extracellular matrix. The erbB2 proto-oncogene is overexpressed in approximately 30% of breast cancers and is a major prognostic parameter when present in invasive disease. A ligand for the erbB2 receptor has not yet been identified but it can be(More)
The type I growth factor receptor family is increasingly recognized as important in the development and maintenance of breast cancer. The family currently consists of four closely related members: the epidermal growth factor receptor (EGF-R/erbB-1), erbB-2, erbB-3 and erbB-4. Putative ligands which bind directly to or indirectly activate erbB-2/3/4 have(More)
Ligands of the EGF/Heregulin family control the growth of epithelial cells by binding to receptors of the erbB family. By searching a large database of cDNA sequences at Human Genome Sciences Inc. we have identified a new encoded protein sequence containing all the conserved elements of the EGF/Heregulin family. The same sequence has recently been(More)
Prurigo pigmentosa (PP) is a rare inflammatory dermatosis originally reported in Japan. Since then, most reports have originated from Asia, and to a lesser extent from Europe. Although the pathogenesis remains unclear, it is now established that PP is linked to ketoacidotic states. Four patients diagnosed with PP were identified from the dermatopathology(More)
Epidermolytic acanthoma (EA) is a rare benign acquired tumor that most commonly presents as a solitary lesion on the trunk, extremities, male genitalia, and face with a male predominance. Cases occurring on the female genitalia have rarely been reported. We describe the case of multiple localized EAs occurring on the vulva of a 31-year-old woman presenting(More)
