【摘要】：目的:研究降鈣素(CT)對(duì)人牙周膜細(xì)胞(PDLCs)的增殖、膠原合成的影響及調(diào)控途徑。方法:采用含CT開(kāi)放閱讀框序列的重組腺病毒Ad.CT轉(zhuǎn)染PDLCs,并以轉(zhuǎn)染空病毒Ad.Null的PDLCs作為對(duì)照,分別用流式細(xì)胞術(shù)檢測(cè)細(xì)胞周期、定量PCR和Western blot檢測(cè)CT、膠原(Ⅰ、Ⅲ、Ⅳ型)、TGF-β的mRNA及蛋白的表達(dá);Ad.CT轉(zhuǎn)染PDLCs同時(shí)給予TGF-β抑制劑LY2109761干預(yù),分別檢測(cè)細(xì)胞周期及其膠原的表達(dá)水平。結(jié)果:轉(zhuǎn)染Ad.CT后PDLCs中CT表達(dá)水平較對(duì)照組顯著升高(P0.05),G2/S/M期細(xì)胞比例顯著高于對(duì)照組(P0.05),Ⅰ、Ⅲ、Ⅳ型膠原蛋白以及TGF-β的表達(dá)顯著高于對(duì)照組(P0.05)。LY2109761能顯著逆轉(zhuǎn)Ad.CT對(duì)于PDLCs增殖及膠原合成的促進(jìn)作用。結(jié)論:CT可能通過(guò)TGF-β途徑促進(jìn)PDLC細(xì)胞的增殖及膠原的合成。
[Abstract]:Aim: to study the effect of calcitonin on the proliferation and collagen synthesis of human periodontal ligament cells (PDLCs). Methods: PDLCs were transfected with recombinant adenovirus Ad.CT containing CT open reading frame sequence and PDLCs transfected with empty virus Ad.Null as control. The cell cycle was detected by flow cytometry, and CTLs, mRNA and protein expression of TGF- 尾 were detected by quantitative PCR and Western blot. PDLCs was transfected with TGF- 尾 inhibitor LY2109761. Results: after transfection of Ad.CT, the expression of CT in PDLCs was significantly higher than that in control group. The expression of type 鈪，
