Within the last 20 years, multiple novel intracellular signal transduction pathways, downstream of plasma membrane receptors, have been discovered. These pathways have been linked to the regulation of diverse cellular events such as proliferation, senescence, differentiation and apoptosis. This review will focus upon the roles of signaling by the ErbB receptor tyrosine kinase family (ErbB1-4) i...
The ErbB/EGFR/HER family of kinases consists of four homologous receptor tyrosine kinases which are important regulatory elements in many cellular processes, including cell proliferation, differentiation, and migration. Somatic mutations in, or over-expression of, the ErbB family is found in many cancers and is correlated with a poor prognosis; particularly, clinically identified mutations foun...

human erythroblastic leukemia viral oncogene homolog 1 (ErbB1)/EGFR that is approved for the treatment of NSCLC6 and pancreatic cancer.7 Although erlotinib has not been studied in AML, gefitinib, another EGFR-TKI, can induce neutrophil differentiation in several EGFR AML cell lines.8,9 In this patient’s bone marrow biopsy, EGFR was expressed on stromal cells, including fibroblasts, but was unde...
Lineage mapping has identified both proliferative and quiescent intestinal stem cells, but the molecular circuitry controlling stem cell quiescence is incompletely understood. By lineage mapping, we show Lrig1, a pan-ErbB inhibitor, marks predominately noncycling, long-lived stem cells that are located at the crypt base and that, upon injury, proliferate and divide to replenish damaged crypts. ...
Lapatinib is an oral, reversible, dual inhibitor of epidermal growth factor receptor ErbB1 (EGFR) and human epidermal growth factor receptor type 2 ErbB2 (HER2). Results of a phase III study comparing lapatinib plus capecitabine with capecitabine alone in women with ErbB2-overexpressing advanced breast cancer previously treated with an anthracycline, a taxane, and trastuzumab were reported earl...
Insufficient fetal surfactant production leads to respiratory distress syndrome among preterm infants. Neuregulin signals the onset of fetal surfactant phospholipid synthesis through formation of erbB receptor dimers. We hypothesized that erbB4 downregulation in fetal type II epithelial cells will downregulate not only fetal surfactant phospholipid synthesis, but also affect proliferation and e...
Protein tyrosine phosphatase (PTP) 1B plays a major role in inhibiting signaling from the insulin and leptin receptors. Recently, PTP1B was found to have an unexpected positive role in ErbB2 signaling in a mouse model of breast cancer, but the mechanism underlying this effect has been unclear. Using human breast epithelial cells grown in a three-dimensional matrix, we found that PTP1B, but not ...
Signaling through the erbB receptor family of tyrosine kinases contributes to the proliferation, differentiation, migration, and survival of a variety of cell types. Abnormalities in members of this receptor family have been shown to play a role in oncogenesis, thus making them attractive targets for anticancer treatments. PF-00299804 is a second-generation irreversible pan-erbB receptor tyrosi...
Heparin-binding epidermal growth factor-like growth factor (HB-EGF), an ErbB1 ligand and prostate stromal growth factor, is an antagonist of androgen receptor (AR) function. In the LNCaP prostate cancer model, HB-EGF reduced AR protein levels and AR transactivation without affecting AR mRNA level or protein turnover. The signal to attenuate AR was mediated by the mammalian target of rapamycin, ...
