- 在P. gingivalis诱导的水泥细胞功能障碍中,lncRNAs的作用尚不清楚.
研究的目的:
- 调查lncRNA,特别是Platr3在P. gingivalis刺激的水泥细胞矿化中的作用和机制.
- 为了阐明涉及P. gingivalis介导的水泥细胞功能抑制的分子途径.
主要方法:
- 在体内使用C57BL/6小鼠 (健康,AP,AP + P. gingivalis) 进行微型CT和免疫组织化学的研究.
- 用P. gingivalis治疗的水泥细胞体内实验,通过qPCR和西方 blot分析基因和蛋白质表达 (Platr3,IL1B,骨质生标记物).
- RNA下拉,RNA免疫沉降和RNA测序以识别Platr3相互作用蛋白和通路 (NUDT21,NF-κB).
主要成果:
- 活体中P. gingivalis感染促进了周周组织破坏和IL1B表达,同时抑制了Platr3.3.
- 在体外,P. gingivalis增加了IL1B,但降低了Platr3和骨质原生标志物在水泥细胞中的表达.

NF-κB-dependent Signaling Pathway
7.4K
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Co-activators and Co-repressors
7.3K
Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...

TGF - β Signaling Pathway
7.3K
The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...
