概括

阻断细胞死亡途径 - - 亡,可以抑制小鼠口腔癌 (OSCC) 的进展. 这种向治疗减少了瘤的生长,并调节了瘤的微环境,这表明OSCC治疗的潜在临床应用.

科学领域:

在瘤学瘤学.
免疫学免疫学免疫学
细胞死亡途径细胞死亡途径

背景情况:

亡在各种病理中起作用,但其在口腔状细胞癌 (OSCC) 中的功能尚不清楚.
了解OSCC中的亡是开发新治疗策略的关键.

研究的目的:

在OSCC小鼠模型中研究亡标记物的表达.
评估在OSCC进展中抑制亡的治疗潜力.

主要方法:

使用了4-NQO诱导的OSCC小鼠模型,密切模仿人类的OSCC.
通过TCGA数据库在老鼠和人类OSCC组织中分析了亡途径标记物 (RIPK-1,RIPK-3,MLKL) 的表达.
给出了necrostatin-1 (NEC-1) 来阻止亡,并评估了瘤进展和免疫细胞概况.

主要成果:

在OSCC组织中增加RIPK-1,RIPK-3和MLKL的表达,RIPK-1的过度表达与人类数据中的癌症严重程度相关.
NEC-1治疗显著降低了OSCC进展,病变严重程度,并改善了组织学特征.
死细胞灭抑制改变了瘤微环境,通过减少髓质衍生抑制细胞和M2巨细胞,同时增加M1巨细胞,改变M2/M1比率并抑制免疫抑制因素.

结论:

阻断瘤亡有效地通过调节瘤微环境和促进抗瘤免疫反应来抑制OSCC的进展.
向亡途径为口腔癌的临床治疗提供了一个有前途的治疗途径.

关键词:

M1 M1 的意思是 M2 已经是M2了在MDSC中,MDSC是MDSC.尼克罗斯塔丁-1-1的使用情况这是OSCCCC的OSCC.在RIPK-1中.尸体的死亡和死亡.

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...
