概括

指 E-box 结合 homeobox 1 (ZEB1) 通过抑制通过AMPK/ROCK1通路的骨质分化促进牙周炎. 沉默ZEB1增强了骨的形成,为牙周炎提供了潜在的治疗点.

科学领域:

口腔生物学口腔生物学
干细胞生物学干细胞生物学
分子医学是分子医学.

背景情况:

牙周炎是一种常见的炎症性疾病,可能导致牙脱落.
指 E-box 结合 homeobox 1 (ZEB1) 在牙周炎受影响的牙组织中受到上调.
了解ZEB1的作用对于开发向性牙周炎疗法至关重要.

研究的目的:

阐明ZEB1导致牙周炎的分子机制.
研究ZEB1,ROCK1和人类牙周介质干细胞 (hPDLSCs) 骨质分化之间的调控关系.

主要方法:

治疗hPDLSCs用脂多糖 (LPS) 诱导牙周炎类炎症.
使用了ZEB1沉默,FX1 (Bcl-6抑制剂) 和ROCK1过度表达.
评估了细胞活力,细胞亡,骨质分化 (ALP,阿利沙林红色染色) 和矿物化.
路西法酶记者测定和ChIP-PCR证实了ZEB1-ROCK1的相互作用.

主要成果:

ZEB1沉默降低了hPDLSC的亡,并增强了骨质的分化和矿化.
治疗FX1减少了ZEB1沉默的有益影响.
ZEB1直接调节了ROCK1促进体活性,影响了ROCK1/AMPK通路.
过度表达ROCK1抵消了ZEB1沉默对Bcl-6/STAT1和骨质生成的影响.

结论:

由LPS引起的牙周炎会影响hPDLSC的增殖和骨质分化.
通过AMPK/ROCK1.1,ZEB1通过调节Bcl-6/STAT1通路来调节这些有害影响.
针对ZEB1/AMPK/ROCK1轴是一个有前途的牙周炎治疗策略.

关键词:

Bcl-6/STAT1 的一个例子.罗克1/AMPK 的情况.在ZEB1中,ZEB1是指ZEB1.在hPDLSC中使用.骨质生成的差异化分化牙周炎是指牙周炎的一种疾病.

Zygotic Development And Stem Cell Formation

Zygotic Development And Stem Cell Formation

The development of all multicellular organisms starts with the fusion of haploid cells called sperm and egg to form a diploid zygote. A zygote is a totipotent cell that can develop into a complete organism. The zygote undergoes cell division or cleavage to form an 8-cell mass. Until this stage, the cells are spherical, loosely attached, and remain totipotent. Totipotent cells are capable of developing both the embryonic and the extraembryonic tissues. However, as they continue to divide, they...
