Reduced cytoplasmic expression of MAGE-A2 predicts tumor aggressiveness and survival: an immunohistochemical analysis.

Publication date: Aug 09, 2020

Melanoma antigen gene A2 (MAGE-A2) is one of the most cancer-testis antigens overexpressed in various types of cancers. Silencing the MAGE-A2 expression inhibited the proliferation of prostate cancer (PCa) cells and increased the chemosensitivity. However, the expression pattern of MAGE-A2 in PCa tissue samples and its prognostic and therapeutic values for PCa patients is still unclear.

In this study, for the first time, the staining pattern and clinical significance of MAGE-A2 were evaluated in 166 paraffin-embedded prostate tissues, including 148 cases of PCa and 18 cases of high-grade prostatic intraepithelial neoplasia (HPIN), by immunohistochemical analysis.

The simultaneous expression of both nuclear and cytoplasmic patterns of MAGE-A2 with different staining intensities was observed among studied cases. Increased expression of MAGE-A2 was significantly found in PCa tissues compared to HPIN cases (P

Taken together, cytoplasmic expression of MAGE-A2 was inversely proportional to the malignant grade and duration of recurrence of the disease in patients with PCa.
