According to the results in the cluster diagram (Figure 4(a)), there were apparent differences in the expression of inflammatory factors including tumor necrosis factor alpha (TNF-α), chemokine C-X-C Motif Ligand 9 (CXCL-9), chemokine C-C motif ligand 12 (CCL-12), granulocyte-macrophage colony-stimulating factor (GM-CSF), chemokine C-C motif ligand 9 (CCL-9), chemokine C-C motif ligand 2 (CCL-2), interleukin 1 alpha (IL-1α), chemokine C-C motif ligand 5 (CCL-5), and tumor necrosis factor receptor superfamily, member 1b (TNFR2), in the asthma model group compared with the control group. The gene discussed is CXCL9; the disease is asthma.
