Through a cDNA microarray-based approach, the authors [56] identified a total of 27 differentially expressed genes between MF and inflammatory dermatoses (20 upregulated and 7 downregulated in MF cases), including tumor necrosis factor receptor (TNFR) and other oncogenes and apoptosis inhibitors. The gene discussed is TNFRSF1A; the disease is mycosis fungoides.
