Descrizione generale
EPHA3 is a receptor tyrosine kinase (RTK) belonging to the largest subgroup of RTKs called ephrin group of receptors. It has a high level of expression from placental stage through the whole developmental process.[1] It is a type I transmembrane protein, and has a membrane-bound ligand. It is both an oncogene and a tumor-suppressor gene.[2][3] This protein resides in both the cytosol and the plasma membrane.[4]
Azioni biochim/fisiol
EPHA3 binds the ephrin-A ligand and has diverse cellular function. Analysis of human colorectal, breast, lung and pancreatic cancer samples shows somatic mutations in the EPHA3 gene.[5] EPHA3 gene expression can be regulated by CD28 and IGF-1 in Jurkat cells and expression of EPHA3 is associated with adherence and motility of malignant T cells.[6] It maintains the less differentiated state of cancer cells, by activating MAPK (mitogen-activated protein kinase) pathway. It is over-expressed in glioblastoma (GBM) cells, especially during the initial stages. It also has higher expression levels in aggressive mesenchymal subtype of GBM.[7] In hepatocellular carcinoma (HCC), it predicts increased invasiveness and poor patient prognosis.[4]

Although EphA3 expression has been associated with progression or prognosis in several types of tumors, the role of EphA3 in hepatocellular carcinoma (HCC) remains unknown. This study sought to investigate the clinicopathological and prognostic relevance of EphA3 expression in HCC

Activation of a cellular senescence program is a common response to prolonged oncogene activation or tumor suppressor loss, providing a physiological mechanism for tumor suppression in premalignant cells. The link between senescence and tumor suppression supports the hypothesis that a

Stimulation of CD28 alone has been shown to regulate cytokine gene transcription and expression of the type 1 insulin-like growth factor receptor (IGF-1R) in lymphocytes. In this study, the ephrin receptor tyrosine kinase ephA3, was identified as a new CD28-responsive

Ephrin receptor tyrosine kinase A3 (EphA3, EC 2.7.10.1) is a member of a unique branch of the kinome in which downstream signaling occurs in both ligand- and receptor-expressing cells. Consequently, the ephrins and ephrin receptor tyrosine kinases often mediate processes

Tyrosine kinases are major regulators of signal transduction cascades involved in cellular proliferation and have important roles in tumorigenesis. We have recently analyzed the tyrosine kinase gene family for alterations in human colorectal cancers and identified somatic mutations in seven
