Abstract:

Objective To investigate the clinical significance of tripartite motif-containing protein 2(TRIM22) gene expression in patients with ulcerative colitis(UC). Methods The UC dataset GSE119600 was downloaded from the GEO database for bioinformatics analysis. Totally,62 patients with UC(UC group) and 60 healthy subjects(healthy control group) at the First Affiliated Hospital of Nanjing Medical University from December 2023 to June 2024 were enrolled. The relative expression levels of serum TRIM22 gene were determined. UC patients were classified into non-active group(22 cases) and active group(40 cases) according to the modified Mayo score. All the patients were classified into mild,moderate and severe groups according to the ulcerative colitis endoscopic index of severity(UCEIS) score. The active UC patients were classified into good prognosis group(29 cases)and poor prognosis group(11 cases)based on the endoscopic reexamination results after 3 months of treatment. Spearman correlation analysis was used to evaluate the correlation between serum TRIM22 and laboratory routine indicators in UC patients. Logistic regression analysis was used to assess the influencing factors of UC. Receiver operating characteristic(ROC) curve was used to evaluate the efficacy of TRIM22 in judging the severity and poor prognosis of UC patients. Results TRIM22 was involved in anti-viral responses,interferon-mediated signaling pathways and inflammatory bowel diseases. The relative expression level of serum TRIM22 gene of UC group was higher than that of healthy control group(P<0.001). The relative expression level of serum TRIM22 gene in active group was higher than that in non-active group(P=0.012). The relative expression level of serum TRIM22 gene in severe group was higher than those in mild and moderate groups(P<0.001). Compared with before treatment,the relative expression level of serum TRIM22 gene in good prognosis group after 3 months of treatment was decreased(P=0.025). Elevated C-reactive protein(CRP) levels and TRIM22 expression were independent risk factors for the occurrence of UC [odds ratios(OR) were 1.10 and 1.69,95% confidence intervals(CI) were 1.85-9.40 and 1.15-2.48,P<0.05]. The areas under curves(AUC) of TRIM22 for judging the active stage of UC,severe disease condition and poor prognosis were 0.71,0.77 and 0.76,respectively. Conclusions TRIM22 is expressed in the serum of UC patients and is related to the severity of the disease. TRIM22 is expected to become a potential molecular marker for UC.
