BACKGROUND: Psoriasis is a classic chronic recurrent inflammatory skin disease characterized by skin inflammation and abnormal biological behaviour of keratinocytes. Although Signal Transducer And Activator Of Transcription 2 (STAT2) was found to play an important role in the Janus kinase (JAK)-STAT signalling pathway and contribute to the pathogenesis of psoriasis, its exact role in psoriasis remains unclear.
METHODS: Using bioinformatics analysis, we identified the key pathways that significantly impacted psoriatic lesions. After identifying the critical molecule gene differentially expressed in multiple public databases using the Kyoto Encyclopaedia of Genes and Genomes (KEGG) enrichment analysis, clinical samples were collected to validate the gene's significance. Its functions and underlying mechanism were also investigated in vitro. Lastly, we evaluated the diagnostic and therapeutic power of the target gene using the receiver operating characteristic curve (ROC), and gene association was assessed using Spearman correlation.
RESULTS: A significant correlation was found between cysteine-aspartic acid protease3 (Caspase3) and STAT2, and functional enrichment analysis revealed that they were both significantly up-regulated in psoriatic skin lesions compared to non-lesional tissues. Functional analysis revealed that Caspase3 functioned downstream of STAT2 in psoriasis. Lastly, we found that Caspase3 and STAT2 could be potential biomarkers for diagnosing and treating psoriasis.
CONCLUSIONS: In summary, STAT2 overexpression contributes to psoriasis progression by regulating Capase3 phosphorylation to induce excessive apoptosis of keratinocytes. Meanwhile, STAT2 and Capase3 were identified as promising biomarkers for the diagnosis and treatment of psoriasis and could be used for individualized treatments.
