circRNA CDR1as Regulated the Proliferation of Human Periodontal Ligament Stem Cells under a Lipopolysaccharide-Induced Inflammatory Condition
Figure 3
The expression levels of CDR1as in periodontal ligament tissues and PDLSCs. (a) The expression of CDR1as in normal tissues () and periodontitis tissues () was determined by RT-qPCR. vs. normal. (b) The TNF-α protein level secreted in the medium by PDLSCs treated with LPS was measured with an ELISA kit. Untreated PDLSCs (0 h) were used as control. vs. control, vs. 3 h. (c) IL-8 and IL-18 protein levels secreted in the medium by PDLSCs treated with LPS at 10 μg/ml for 3 h were measured with an ELISA kit. Untreated PDLSCs were used as control. vs. control. (d) The expression levels of CDR1as in LPS-treated PDLSCs were analyzed by RT-qPCR. Untreated PDLSCs were used as control. vs. control.
