Abstract
LncRNA MAFG‐AS1 is predicted to interact with miR‐146a, which can target toll‐like receptor 4 (TLR4), a key player in periodontitis. This study aimed to investigate the roles of MAFG‐AS1 in periodontitis. It was observed that MAFG‐AS1 was downregulated in the human periodontal ligament stem cells (PDLSCs) derived from periodontitis‐affected teeth. Dual luciferase assay revealed that co‐transfection of MAFG‐AS1 expression vector and miR‐146a mimic showed significantly lower relative luciferase activity comparing to co‐transfection of MAFG‐AS1 expression vector and negative control (NC) miRNA. However, MAFG‐AS1 and miR‐146a failed to affect each other. Interestingly, MAFG‐AS1 overexpression led to the upregulated TLR4. In addition, MAFG‐AS1 overexpression also led to the inhibited proliferation of PDLSCs. Therefore, MAFG‐AS1 may regulate the proliferation of PDLSCs and the expression of TLR4 to participate in periodontitis.This publication has 21 references indexed in Scilit:
