Abstract:
Objective To study the effect of baicalin on the expression of receptor activator of nuclear factor-?B ligand (RANKL) and osteoprotegerin (OPG) in cultured human periodontal ligament cells (HPDL cells) as well as its action mechanism. Methods We first constructed small interferring RNA (siRNA) eukaryotic expression vector targeted transforming growth factor ?Ⅱ receptor (TGF-?RⅡ),and then transfected it into T cells. Then HPDL cells together with T cells transfected with siRNA or not were placed in medium that had been added with lipopolysaccharide (LPS) and baicalin. They were divided into six groups and cultured for 48 hours. Reverse transcriptase-polymerase chain reaction (RT-PCR) was used to observe the effect of baicalin on OPG-RANKL expression in HPDL cells. Results The clone sequence correctly identified by RT-PCR was consistent with the designed target sequence. The recombinant vector was constructed successfully and the expression of TGF-?ⅡR of T cells which had been transfected with siRNA1 was inhibited obviously. Ratio of RANKL/OPG in each group differed significantly (P
