Differentially expressed genes (DEGs) were identified using DESeq2 and intersected with Hippo pathway genes and weighted gene co-expression network analysis (WGCNA) results to obtain differentially expressed Hippo-related genes (DE-HRGs). Candidate genes were screened using the least absolute shrinkage and selection operator (LASSO) regression, support vector machine-recursive feature elimination (SVM-RFE), and the Boruta algorithm. Their diagnostic value was assessed with receiver operating characteristic (ROC) curves and neural network model. To validate the findings, a rat OA model was established by using Hulth method with control and model groups, 8 rats in each group. The control group received no treatment, while OA group were underwent surgical modeling. Four weeks after modeling, X-ray examinations of knee joints were conducted to observe joint space, the shape of joint surfaces, and the formation of bone spurs. The expression levels of epidermal growth factor receptor (EGFR) and protein kinase AMP-activated non-catalytic subunit beta 2 (PRKAB2) in cartilage tissue were detected by real-time fluorescence quantitative polymerase chain reaction (RT-qPCR).
