Figure 7. The expression of IL-1β and the correlation of LINC00623, miR-101, HRAS and IL-1β in tissue samples. (A–C) The correlation of LINC00623, miR-101 and HRAS expression was analyzed using Spearman’s rank correlation analysis. (D) The mRNA expression of IL-1β in normal and OA tissues were detected using real-time PCR. The data are presented as mean ± SD of three independent experiments. **P<0.01. (E–G) The correlation of IL-1β with LINC00623, miR-101 and HRAS expression, respectively, was analyzed using Spearman’s rank correlation analysis.
