Figure Legend Snippet: Top 10 differentially expressed circRNAs (degenerated vs. non-degenerated)
Techniques Used:
Figure Legend Snippet: a Scatter plot of circRNA expression. The circRNAs above the top green line and below the bottom green line indicated more than a twofold change between the degenerated and normal IVD NP tissues. b Volcano Plot of the differentially expressed circRNAs. The red points in the plot represent differentially expressed circRNAs with statistical significance. c Hierarchical clustering shows the distinguishable circRNA expression profile between the two groups and homogeneity within the groups. d The sequence of the amplified Circ-4099 product was completely consistent with CircBase. e Co-localization between circ-4099 (red) and miR-616-5p (green) was observed by RNA in situ hybridization in hNP cells after co-transfection with circ-4099-expressing and miR-616-5p-expressing vectors. The nuclei were stained with DAPI (blue). Scale bar = 10 µm. f The expression levels of circ-4099 are significantly higher in degenerated NP tissues than in non-degenerated NP tissues. g – i The expression levels of circ-68610/2069/92328 are higher in degenerated NP tissues than in non-degenerated NP tissues. j qRT-PCR analysis shows that TNF-α upregulates the expression of circ-4099 in a dose-dependent and time-dependent manner. For time-dependent studies, 50 ng/ml TNF-α was used. k hNP cells were transfected with the circ-4099-Luc promoter and the induction in luciferase activity was measured following TNF-α treatment ( P < 0.001)

Figure Legend Snippet: a Plasmid map of the Circ-4099 over-expression plasmid. b The qPCR products were used to confirm the Circ-4099 sequence. c , d hNP cells were transfected with Circ-4099, NC (PLCDH-ciR) or negative control, and total RNA was collected. qPCR was used to detect the expression of Circ-4099 and its linear RNA (DENND5A) (linear + circRNA). The results showed that the Circ-4099 over-expression plasmid can extremely enhance Circ-4099 expression. These data confirm the validity and efficiency of the Circ-4099 over-expression plasmid. e , f qRT-PCR showed that Circ-4099 over-expression led to increased Collagen II and Aggrecan mRNA expression, which was suppressed by treatment with miR-616-5p mimics, while MMP3 and ADAMTS5 showed few significant differences in regulation. g , h Western blotting also showed that he Collagen II and Aggrecan protein expression levels were significantly increased by circ-4099 over-expression treatment. We next tested the effects of Circ-4099 on expression of inflammatory cytokines in hNP. i , j The IL-1β, TNF-α, and PGE2 mRNA levels were significantly suppressed in hNP cells transduced with Circ-4099 over-expression plasmid, which was inhibited by treatment with miR-616-5p mimics. k , l IL-1β, TNF-α, IL-6, and PGE2 cytokine release into medium was detected by ELISA, which showed similar results
