Additionally, after differential gene expression analysis, the components NFKB1 (LFC = 1.69), NFKB2 (LFC = 0.81), RELA (LFC = 1.56), IKBKG (LFC = 1.36), MAP3K14 (LFC = 0.87), CHUK (LFC = 1.01), and IKBKB (LFC = 0.87) were significantly more highly expressed in RS, whereas REL (LFC = −0.71) was more highly expressed in CLL. The gene discussed is CHUK; the disease is B-cell chronic lymphocytic leukemia.
