The MiR-125 family can be divided into miR-125a and miR-125b subfamilies.361 Raaby et al. found that the expression of miR-125a was downregulated in skin lesions of patients with psoriasis,362 and Su et al. also found that miR-125a expression was negatively correlated with the surface area of skin lesions, the Psoriasis Area and Severity Index (PASI) score, the use of phototherapy, and the expression of TNF-α, IL-1β, and IL-17 in patients with psoriasis, which might be indicators for psoriasis. Here, IL1B is linked to psoriasis.
