Fig. 2From: LncRNA papillary thyroid carcinoma susceptibility candidate 3 (PTCSC3) regulates the proliferation of human periodontal ligament stem cells and toll-like receptor 4 (TLR4) expression to improve periodontitisExpression levels of PTCSC3 and TLR4 were inversely correlated in periodontitis-affected PDLSCs. Linear regression showed that expression levels of PTCSC3 and TLR4 were significantly and inversely correlated in periodontitis-affect PDLSCs (a). In contrast, the correlation between PTCSC3 and TLR4 was not significant in healthy PDLSCs (b)Back to article page
