After performing differential gene expression analysis, ssGSEA, and immune infiltration analysis, LLPS-related genes modulating ubiquitination, key immune cells, and immune-related pathways were acquired. The correlations between LLPS-related genes and ubiquitination, key immune-related pathways were explored, respectively. The diagnostic genes were identified by four machine learning algorithms, followed by evaluation to predict the performance of the machine learning models on ubiquitination using receiver operating characteristic curves and a confusion matrix.\n                    <jats:italic toggle=\"yes\">In vitro<\/jats:italic>\n                    experiments were applied to explore the function of signal transducer and activator of transcription 1 (\n                    <jats:italic toggle=\"yes\">STAT1<\/jats:italic>\n                    ) in DN. Totally, 513 differentially expressed genes were screened between the DN and control groups. The activity of the ubiquitin-mediated proteolysis pathway exhibited a significant difference between the DN and control samples. The fraction of a total of 10 immune cells exhibited a significant difference between the lower and higher ubiquitination groups. Totally, nine LLPS-related genes modulating ubiquitination were acquired, and these genes modulating ubiquitination were enriched in ubiquitin pathways and significantly positively correlated with the complement, IFN-\u03b1, and IFN-\u03b3 pathways.
