TRPV1 was presented in the dorsal root ganglion, increasing with fibromyalgia pain (Figure 2A, 133.89 ± 4.63%, red column, * p < 0.05, n = 6), while 2 Hz EA inhibited this overexpression (Figure 2A, 102.93 ± 2.57%, red column, # p < 0.05, n = 6). The gene discussed is TRPV1; the disease is fibromyalgia.
