Interestingly, a series of commonly upregulated genes were identified in brucellosis patients, with seven genes/transcription factors (RGS1, DUSP1, FOS, PPP1R15A, TNFAIP3, HLA‐E, and ZFP36) being the most frequent (nine times among nine clusters) (Figure 5A, Figure 7SA). The gene discussed is DUSP1; the disease is brucellosis.
