Fig. 3From: ITGB1 alleviates osteoarthritis by inhibiting cartilage inflammation and apoptosis via activating cAMP pathwayHub genes analysis. A Hub genes ridgeline plot. The horizontal coordinate was the expression of hub gene, the shape of the mountain indicated the dispersion between a set of data, and the height was the number of samples corresponding to the amount of gene expression. B Hub genes principal component analysis diagram. The axes PC1 and PC2 in the figure were the first and second principal components; Dots represented samples, and different colors represented different groups. C Receiver operating characteristic curves of selected genes ITGB1, COL5A1, COL1A1, THBS2, LAMA1, and COL12A1Back to article page
