In this study, we clarify the function of Alpha-2-glycoprotein 1, zinc-binding (ZAG) as a tumor immunoregulatory mechanism via androgen receptor (AR) signal in breast cancer.
Others
Single cell suspension is prepared from the tumor tissue collected from the primary breast cancer excision sample, and the sample is evaluated by multicolor flow cytometry and flow bead array to perform phenotypic analysis of intratumoral immune cells and cytokine quantification. Subsequently, AR, ZAG, AR, PD-L1 expression and tumor infiltrating immune cells (TILs) are evaluated by immunostaining in the same specimen. The correlation between ZAG, intratumoral immune cell composition, cytokine composition, expression of various immune checkpoint-related molecules, and TILs are analyzed.
The action of recombinant ZAG on primary immune cells or model cell lines, corresponding to immune cells considered to be the primary target of ZAG will be clarified by in-vtro study.

For 45 breast cancer clinical specimens, the number of tumor infiltrating leukocytes and the ratio of various immune cell fractions to them are measured by multicolor flow cytometry. AR and ZAG expression was quantified by immunostaining. AR expression showed a positive correlation with the proportions of NK cells and NKT cells, and ZAG expression showed an inverse correlation with the proportions with Monocytes (including Macrophage-like cells) and MDSC.
