Background Psoriasis is a chronic hyperproliferative inflammatory disease, in which genetic and environmental factors have an important role, but the exact cause is yet unknown. Circular RNAs (circRNAs) are regulatory noncoding RNAs. They play an important role in multiple physiological and pathological processes, such as cancer, cardiovascular diseases, and neuronal diseases. Some circRNAs are involved in regulating immunity, inflammation, and cell proliferation in many types of cells. Aim To detect the expression of circRNA (Circ0061012) in psoriatic skin of diseased patients as compared with normal control persons to investigate the possible role of circRNA in psoriasis pathogenesis and its correlation with disease severity. Patients and methods The present study included 30 psoriatic patients and 30 healthy controls. A 4-mm punch skin biopsy was taken from patients (psoriatic lesion) and controls, and it was kept in the lysis solution for the stability of the studied parameters and was kept frozen at ‑80°Celsius till analysis of circRNA by real-time polymerase chain reaction. Results The tissue level of circRNA (Circ0061012) was significantly higher among patients with psoriasis as compared with normal control individuals. Conclusion circRNA could contribute to psoriasis pathogenesis through its immunomodulatory role, so it might be a therapeutic target in the future.
