The course of psoriasis is long and recurrence is common; pathogenesis is not completely understood. However, there is an association between advancement of psoriasis and aberrant microRNA (miR or miRNA)‑155 expression. Through bioinformatics, the present study aimed to analyze the differentially expressed genes and miRNAs in psoriasis and its biological mechanism and function psoriatic inflammation. First of all, differentially expressed genes (DEGs) and miRNAs (DEMs) in patients with psoriasis were identified using GEO2R interactive web application. A psoriasis inflammatory model was established using lipopolysaccharide (LPS)‑treated HaCaT keratinocytes, which were transfected with miR‑155 mimic or inhibitor. Cell Counting Kit‑8 was used for the assessment of cell viability and proliferation, and changes in the cell cycle were examined using flow cytometry. ELISA and reverse transcription‑quantitative PCR (RT‑qPCR) were used to detect the expression levels of the inflammatory factors IL‑1β and IL‑6. The dual‑luciferase reporter assay was used to verify the targeting association between miR‑155‑5p and IFN regulatory factor 2 binding protein 2 (IRF2BP2). To verify the targeting association of miR‑155 and the IRF2BP2/kruppel‑like factor 2 (KLF2)/NF‑κB signaling pathway, expression levels of IRF2BP2, KLF2 and p65 were identified by RT‑qPCR and western blotting. IRF2BP2 levels were also confirmed by immunofluorescence, in conjunction with bioinformatics database analysis. Overexpression of miR‑155 inhibited proliferation of HaCaT cells and increased the number of cells in S phase and decreasing number of cells in G1 and G2 phase. In the LPS‑induced inflammatory state, miR‑155 overexpression heightened the inflammatory response of HaCaT cells while inhibition of miR‑155 lessened it. Suppression of inflammatory cytokine expression by miR‑155‑5p inhibitor was reversed by knockdown of IRF2BP2. miR‑155 was shown to interact with IRF2BP2 to negatively regulate its expression, leading to decreased KLF2 expression and increased p65 expression and secretion of inflammatory factors, intensifying the inflammatory response of HaCaT cells. Therefore, miR‑155 may contribute to development of psoriasis by inducing tissue and cell damage by increasing the inflammatory response of HaCaT cells via the IRF2BP2/KLF2/NF‑κB pathway. In conclusion, the results of the present study offer novel perspectives on the role of miR‑155 in the onset and progression of psoriasis.</p>","PeriodicalId":14086,"journal":{"name":"International journal of molecular medicine","volume":"54 5","pages":""},"PeriodicalIF":5.7,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11374146/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142107175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Negative pressure wound therapy (NPWT) promotes DFU wound healing through an undetermined mechanism. In the present study, RNA sequencing was performed on wound granulation tissue from 3 patients with DFU before and after 1 week of NPWT. The fused in sarcoma (FUS) and interleukin enhancer binding factor 2 (ILF2) encoding RNA‑binding proteins (RBPs) were screened from the sequencing data, and wound tissue samples from 24 patients with DFU were validated and analyzed before and after receiving NPWT by reverse transcription‑quantitative PCR, western blotting and immunohistochemistry. In addition, <i>in vitro</i> and <i>in vivo</i> experiments were conducted to determine the effect of the expression of FUS and ILF2 on the function of human epidermal keratinocyte cells (HaCaT cells) and the healing of diabetic skin wounds. The results indicated that NPWT induced the upregulation of 101 genes and the downregulation of 98 genes in DFU wound granulation tissue. After NPWT, the expression of FUS and ILF2 was significantly upregulated (P<0.05). Pearson's correlation coefficient showed that the changes in FUS and ILF2 before and after NPWT were negatively correlated with changes in white blood cells, the neutrophil percentage, C‑reactive protein, tumor necrosis factor‑α, reactive oxygen species, lipid peroxides, matrix metalloproteinase (MMP) 2 and MMP9 (P<0.05), but positively correlated with the anti‑inflammatory factor, IL‑4 (P<0.01). There was also a positive correlation (P<0.05) with the 4‑week ulcer healing rate. Additionally, the knockdown of FUS and ILF2 expression inhibited the proliferation and migration of HaCaT cells, while increasing cell apoptosis. <i>In vivo</i>, the knockdown of FUS and ILF2 significantly reduced the rate of skin wound healing in diabetic mice.

OS stem cells (OSCs) and anoikis resistance are considered to be essential for tumor metastasis formation. However, the underlying mechanisms involved in the maintenance of a stem‑cell phenotype and anoikis resistance in OS are mostly unknown. Fos‑like antigen 1 (FOSL1) is important in maintaining a stem‑like phenotype in various cancers; however, its role in OSCs and anoikis resistance remains unclear. In the present study, the dynamic expression patterns of FOSL1 were investigated during the acquisition of cancer stem‑like properties using RNA sequencing, PCR, western blotting and immunofluorescence. Flow cytometry, tumor‑sphere formation, clone formation assays, anoikis assays, western blotting and <i>in vivo</i> xenograft and metastasis models were used to further investigate the responses of the stem‑cell phenotype and anoikis resistance to FOSL1 overexpression or silencing in OS cell lines. The underlying molecular mechanisms were evaluated, focusing on whether SOX2 is crucially involved in FOSL1‑mediated stemness and anoikis in OS. FOSL1 expression was observed to be upregulated in OSCs and promoted tumor‑sphere formation, clone formation and tumorigenesis in OS cells. FOSL1 expression correlated positively with the expression of stemness‑related factors (SOX2, NANOG, CD117 and Stro1). Moreover, FOSL1 facilitated OS cell anoikis resistance and promoted metastases by regulating the expression of apoptosis related proteins BCL2 and BAX. Mechanistically, FOSL1 upregulated SOX2 expression by interacting with the SOX2 promoter and activating its transcription. The results also showed that SOX2 is critical for FOSL1‑mediated stem‑like properties and anoikis resistance. The current findings indicated that FOSL1 is an important regulator that promotes a stem cell‑like phenotype and anoikis resistance to facilitate tumorigenesis and metastasis in OS by regulating the transcription of SOX2.
