Abstract:
Psoriatic skin is characterized by a deregulated profile of miRNAs that are contributing in disease development. In this study, we focus on miR-31, one of the upregulated miRNAs known to promote keratinocytes proliferation and migration. Moreover, miR-31 expression induction was dependent on a large panel of cytokines including IL-22. Here, we aimed at investigating the relationship between miR-31-5p and IL-22 axis; and by searching novel molecular target for miR-31-5p in keratinocytes. Our data identify a direct correlation between miR-31-5p and IL-22 in psoriasis with Pwp1 as new potential target. These findings confirm the important role of miR-31 in psoriasis onset and provide a basis for further investigations in miRNAs field in context of skin diseases.
Insights
This study reveals a direct correlation between miR-31-5p and IL-22 in psoriatic skin, identifying Pwp1 as a novel target. These findings highlight the role of microRNAs in psoriasis pathogenesis.
Area of Science:
- Dermatology
- Molecular Biology
- Genetics
Background:
- Psoriatic skin exhibits dysregulated microRNA (miRNA) profiles contributing to disease development.
- miR-31, a known upregulated miRNA, promotes keratinocyte proliferation and migration in psoriasis.
- Interleukin-22 (IL-22) is a key cytokine involved in inducing miR-31 expression.
Purpose of the Study:
- To investigate the relationship between miR-31-5p and the IL-22 axis in psoriasis.
- To identify novel molecular targets of miR-31-5p within keratinocytes.
Main Methods:
- Analysis of miR-31-5p and IL-22 expression in psoriatic skin.
- In silico and in vitro validation of potential miR-31-5p targets in keratinocytes.
Main Results:
- A direct correlation was established between miR-31-5p and IL-22 levels in psoriasis.
- Pwp1 was identified as a novel potential molecular target of miR-31-5p in keratinocytes.
Conclusions:
- miR-31-5p and IL-22 play significant roles in the pathogenesis of psoriasis.
- Pwp1 emerges as a potential therapeutic target for psoriasis interventions.

Perpendicular-Axis Theorem
Consider a circular disc of mass M and radius R lying along an x-y plane. The origin lies at the center of the disc, and the z-axis is perpendicular to the disc's plane. All three axes coincide at the disc's center. The moment of inertia of this...
