概括

吸管内运输80 (IFT80) 删除通过减少骨质生成和细胞活性,损害牙口骨的愈合. 恢复TAZ表达促进了愈合,这表明IFT80

科学领域:

细胞生物学细胞生物学
再生医学是一种再生医学.
口腔生物学口腔生物学

背景情况:

内运输 (IFT) 蛋白质对于初级乳毛功能至关重要,调节细胞生长和分化.
IFT80在提取牙口的早期骨愈合中的作用仍然在很大程度上未被探索.
膜骨衍生介质干细胞 (aBMSCs) 是骨再生过程中的关键参与者.

研究的目的:

调查aBMSC中IFT80删除对提取位骨早期愈合的影响.
阐明潜在的分子机制,特别是TAZ/RUNX2通路的参与.

主要方法:

TGF - β Signaling Pathway

TGF - β Signaling Pathway

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...

Regulation of Angiogenesis and Blood Supply

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...
