Figure Lengend Snippet: A: dPCR results of human chondrocytes (HC, left), Fibroblast-Like Synoviocytes (HFLS, middle) and muscular cells (CHQ; right) cultures supernatants infected with OROV at MOI 0.1 and collected at different times (24, 48, 72 h p.i.). The graphs show 18 points (except HFLS with 12 points) per condition, as well as the mean and geometric standard deviation. ns: not significant; *: p-value < 0.05; **: p-value < 0.01; ***: p-value < 0.001; ****: p-value < 0.0001 (Dunn-Bonferroni non-parametric test). B: HC (left), HFLS (middle), and CHQ (right) cells were infected with OROV at different MOIs. Cell lysates were collected at 48 or 72h p.i. and analysed by Western blot, using antibodies against calnexin (CNX) as internal control and against the N protein of OROV (OROV N). C: The supernatants from HC (left), HFLS (middle) and CHQ (right) cultures were collected at different times after infection with OROV at MOI 0.1. The viral titer was determined on Vero cells using xCELLigence technology from a standard range. Each condition has 6 replicates. ns: not significant; *: p-value < 0.05; **: p-value < 0.01 (Dunn-Bonferroni non-parametric test).

Figure Lengend Snippet: The m 6 A levels of PINK1 mRNA were confirmed by m6A RIP-qPCR in the synovial tissues of sham and MIA-induced TMJOA rats ( A ), primary FLSs from sham and MIA-induced TMJOA rats ( B ), BLM-treated hFLSs ( C ), and METTL3-silenced hFLSs after treatment with BLM ( D ), ** P < 0.01; *** P < 0.001. E Potential m6A sites for PINK1 mRNA. MeRIP-qPCR analysis of PINK1 m 6 A mRNA levels at the 2028 ( F ), 2074 ( G ), 2174 ( H ), and 2483 ( I ) sites in hFLSs after transfection with shMETTL3 (IME4), ** P < 0.01; *** P < 0.001. J After IME4 silencing, the level of PINK1 was monitored via RT-qPCR in BLM-induced hFLSs treated with 2.5 μM actinomycin D for 0, 4, 8, and 12 h. The estimated half-life of PINK1 mRNA was 7.83 h in the BLM group and 11.33 h after IME4 knockdown. Data are mean ± SD from three independent experiments. *** P < 0.001 vs. the CTRL group; ### P < 0.001 vs. the BLM group.
