From: Identification of Marker Genes for Differential Diagnosis of Chronic Fatigue Syndrome
Differentiation of CFS and non-CFS cases by expression levels of nine marker genes. (A) The expressions of nine marker genes were validated by real-time PCR, and their mean values were compared in 18 newly enrolled CFS patients (indicated as “C”) with 12 non-CFS patients (indicated as “N”). Values are mean fold changes ± SD. #P < 0.05 by the unpaired t test. (B) The expression levels of nine genes from 18 CFS and 12 non-CFS patients were differentiated using hierarchical cluster analysis by the results of average linkage and distance metric of cosine θ. CFS and non-CFS patients are indicated as red and yellow bars, respectively. Patient’s numbers indicated at the bottom of columns are corresponding to the numbers in Table 1.
