Introduction to Human epididymis protein 4 (HE4)
Human epididymis protein 4 (HE4), also known as whey acidic protein-four-disulfide core domain 2 (WFDC2), is a secreted glycoprotein and a member of the whey acidic protein (WAP) family with a molecular weight of 22-26kDa. Mature HE4 consists of 94 amino acids and contains two highly conserved WAP domains.
The HE4 coding gene WFDC2 is expressed in various epithelial cells such as the fallopian tube epithelium and endometrial glands in women, the distal end of the epididymis and the vas deferens in men. The expression level of HE4 is low in normal tissues, but it is usually overexpressed in tumor tissues of ovarian cancer and endometrial cancer. Gene overexpression experiments showed that HE4 overexpression promotes anchorage-independent growth of endometrial cancer cells, inhances the ability of cancer cells to migrate and invade matrix gel or muscle layer. HE4 plays an important role in the proliferation and malignant transformation of cancer cells, and it has important reference significance for the diagnosis prognosis judgment, as well as monitoring of ovarian cancer, endometrial cancer and other tumors.
