When assessing the CXCR4, CD69, HSPA1A, ZFP36, IL7R and TXNIP gene panel, we found levels of all 6 markers to be increased in nonlesional vs. lesional MF in malignant cells, but not in other lymphoid cell subsets (helper T cells, regulatory T cells, cytotoxic T cells, and NK cells; Fig. 8 H, Fig. S7G, Table S19). Here, CD69 is linked to mycosis fungoides.
