Description : Eph (erythropoietin-producing hepatocellular) family tyrosine kinase receptors consist of two groups: EphA group members respond to ephrin-A, which is anchored to the cell membrane by glycosylphosphatidylinositol, whereas EphB group members respond to ephrin-B, containing a transmembrane domain. High levels of EphA2 have been documented in many cell models and clinical specimens of human cancer, including metastatic melanoma and breast, prostate, lung, renal cell, colon, and esophageal carcinomas.

Ask a question
What are the treatment strategies for EPHA2? 08/01/2021

Therapeutic strategies for EPHA2 include inhibition of its expression, blocking its signal transduction pathway, and modulating its interaction with ligands. These strategies may involve the use of small molecule inhibitors, antibodies, or other types of therapeutics.

How does EPHA2 expression level relate to the occurrence and progression of the disease? 07/27/2021

The expression level of EPHA2 is associated with the occurrence and progression of a variety of diseases. For example, in tumors such as lung, breast, and colorectal cancer, EPHA2 expression levels may be elevated and correlated with the degree of malignancy and poor prognosis of the tumor.

How does EPHA2 expression level relate to tumor prognosis? 06/10/2021

In some tumors, EPHA2 expression levels are associated with poor prognosis in patients. For example, patients with lung cancer who express EPHA2 often have shorter survival. Therefore, the expression level of EPHA2 may be one of the indicators to predict tumor prognosis.

How can diseases be diagnosed by detecting EPHA2 expression levels? 05/21/2021

Some diseases can be diagnosed by measuring EPHA2 expression levels, such as immunohistochemistry, western blotting, and real-time PCR.

Could EPHA2 be used as a target for the treatment of certain diseases? 10/18/2020

Yes, EPHA2 can be used as a target for the treatment of certain diseases. For example, inhibition of EPHA2 expression can inhibit tumor growth and spread, so EPHA2 can serve as a potential therapeutic target. In addition, regulating the expression level of EPHA2 may also be helpful in the treatment of diseases such as the nervous system and cardiovascular system.

What is the role of EPHA2 in cancer metastasis? 08/22/2020

EPHA2 can promote cancer metastasis and affect the spread and spread of cancer by regulating processes such as invasion and migration of tumor cells. Therefore, inhibition of EPHA2 expression or blocking its signal transduction pathway may have a potential therapeutic effect on inhibiting cancer metastasis.
