Aims To study the expression of certain non-coding RNAs, Interferon Alpha Inducible Protein 6 (IFI6), previously named Glucose-dependent Insulinotropic Polypeptide 3 (G1P-3), and nucleolar phosphoprotein (in serum and tissue), and to attempt to elucidate their role in the pathogenesis of psoriasis, which in turn might help in treatment. Methods Twenty patients with psoriasis and 20 healthy subjects were included in this study. Serum and skin biopsies were obtained from all participants. Molecular biology techniques were employed to estimate the expression levels of long noncoding G1P-3 and nucleolar phosphoprotein in serum and skin biopsy. Results Psoriasis patients had a mean age of 41.85 ± 12.29. The median serum G1P-3 level of the patients’ group (3.330) was significantly higher than that of the control group (1.085) (\textit{P} ≤ 0.001). Tissue G1P-3 level of the patients’ group (6.495) was also significantly higher compared to that of controls (1.040) (\textit{P} ≤ 0.001). Similarly, for nucleolar phosphoprotein, the median serum level of patients’ group (2.030) was significantly higher than that of controls (1.040) (\textit{P} ≤ 0.001) and median tissue level (5.425) was also significantly higher than that of controls (1.040) (\textit{P} ≤ 0.001). Limitations In this study, only outpatients were included and follow-up was not well-handled. For future work, follow-up can be considered. Conclusion Long non-coding G1P-3 as well as nucleolar phosphoprotein may be considered as genetic markers for psoriasis susceptibility. In future, these might provide a novel direction for advances in psoriasis treatment. }, volume = 89, journal = {Indian Journal of Dermatology, Venereology and Leprology}, issn = {0378-6323}, issn = {0973-3922}, url = {https://doi.org/10.25259/IJDVL_1215_2021}, doi = {10.25259/IJDVL_1215_2021} }
