Results: Patients with vitiligo exhibited significant downregulation of CUL3 (0.27 ± 0.03 vs. 1 ± 0.58; p = 0.013), NRF2 (0.37 ± 0.26 vs. 1 ± 0.8; p = 0.001), and FOXP3 (0.09 ± 0.2 vs. 1 ± 0.3; p = 0.001), alongside the upregulation of miRNA-146a (4.7 ± 1.9 vs. 1 ± 0.8; p = 0.001), NF-κB (4.7 ± 1.9 vs. 1 ± 0.5; p = 0.001), IL-6 (2.8 ± 1.5 vs. 1 ± 0.4; p = 0.001), and TNF-α (2.2 ± 1.1 vs. 1 ± 0.3; p = 0.001). The gene discussed is CUL3; the disease is vitiligo.
