產品描述：

The generation of the recombinant human melanoma-associated antigen 4 (MAGEA4) includes the fusion of the 10xHis-tag gene with all genes encoding the human MAGEA4, the cloning of the synthesized gene into the plasmid vector, the transfection of the cloned vector into the mammalian cells. This recombinant human MAGEA4 protein was quality tested in the purity, endotoxin level, and bioactivity. Its purity reached up to 90% measured by SDS-PAGE. The LAL method estimated the endotoxin content of this MAGEA4 protein less than 1.0 EU/ug. In the functional ELISA, this MAGEA4 protein can bind to the recombinant antibody against MAGEA4, with the EC₅₀ of 30.33-43.10 ng/mL.

MAGEA4 is up-regulated in various malignant tumors such as oral squamous cell carcinoma, non-small cell lung cancer, pancreatic cancer, and breast cancer. It is not expressed in adult normal tissues but in germ cells. MAGEA4 plays a dual role as a tumor suppressor and tumor promoter during tumorigenesis. As a tumor promoter, MAGEA4 is highly expressed in liver cancer cells and inhibits caspase-mediated apoptosis, reduces the sensitivity to chemotherapy, and ultimately reduces p53 activity, thereby inhibiting apoptosis. MACEA4 acts as a master regulator of Tregs development and function. Tregs are involved in tumor escape from the immune system. MAGEA4 in pancreatic cancer inhibits T cell proliferation, thus facilitating tumor cell survival. As a tumor-specific antigen, MAGEA4 is helpful to establish a new antitumor method.

靶點詳情

功能：

Regulates cell proliferation through the inhibition of cell cycle arrest at the G1 phase. Also negatively regulates p53-mediated apoptosis.
基因功能參考文獻：
1. MAGEA4 was positively correlated with TWIST1, and its knockdown inhibited EMT in TE3 cells. PMID: 28653599
2. Because of the significant correlation of MAGEA4 and indices of poor prognosis, the role of this CTA may be confirmed in Esophageal squamous cell carcinoma (ESCC) aggressiveness and metastasis. Therefore, MAGEA4 may be a promising therapeutic candidate for suppressing ESCC aggressiveness PMID: 30197348
3. Study shows that whereas MAGEA4 expression by itself may be indicative of a poor prognosis in primary lung cancer, its prognostic value depends entirely on its subcellular localization and on the p53 status. The accumulation of nuclear MAGEA4 expression without p53 expression is significantly associated with poor survival, implying that MAGEA4 inhibits apoptosis and increases tumorigenesis. PMID: 29901069
4. MAGE-A4 depletion from MAGE-A4-expressing cancer cells destabilizes RAD18. PMID: 27377895
5. Our results support...the potential utility of MAGEA4 as an ancillary diagnostic marker for synovial sarcoma PMID: 28744588
6. some autoantibodies, such as anti-MAGEA4, anti-CTAG1 or anti-TP53 and their combinations could possibly contribute to the development of cancer early detection tests (not necessarily restricted to gastric cancer) when being combined with other markers. PMID: 27140836

8. High MAGE-A4 expression is associated with Lung Cancer. PMID: 27793776
9. Results found concomitant overexpression of MAGEA4 and TWIST1 in esophageal squamous cell carcinoma (ESCC). Also, it showed a correlation between MAGEA4 and TWIST1 expression, which was found as indirect binding of TWIST1 to the E-boxes in the MAGEA4 promoter revealing transcriptional upregulation of MAGEA4 by TWIST1.
