Besides, while preparing the draft of the present manuscript, a research reported that stable Glo1 knock-down in DU145 PCa cells and human malignant melanoma was paralleled by pronounced PD-L1 expression [29], thus not only supporting our data but also confirming our perspective of a causative role of Glo1 in controlling PD-L1 expression in other neoplasms. This evidence concerns the gene CD274 and melanoma.
