失调的河马信号驱动胃癌. 研究人员将USP12确定为一种关键的二维基因酶,通过稳定YAP,促进癌症的进展. 阻止USP12可能为胃癌提供一种新的治疗策略.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 生物化学 生物化学
背景情况:
- 河马信号通路的失调是胃癌进展的关键驱动因素.
- 准Hippo/YAP轴是一个有希望的治疗策略,但缺乏有效的药物.
- 乌比基提尼修改显著影响Hippo/YAP信号和癌症的发展.
研究的目的:
- 确定新的治疗点和抑制胃癌中Hippo/YAP轴的机制.
- 为了研究duebiquitinases在胃癌中调节Hippo/YAP通路中的作用.
主要方法:
- 一个小的干扰RNA库的duebiquitinase的选.
- 对患者数据和基因表达的生物信息分析.
- 免疫和免疫沉测试以确定蛋白质局部化和相互作用.
- 西方涂抹以评估蛋白质无处不在水平.
主要成果:
- USP12被确定为一个关键的二维基基因酶,参与胃癌的进展.
- 消耗USP12抑制了胃癌的生长,而过度消耗则促进了胃癌的生长.
- USP12定位在核中,与YAP相互作用,并通过抑制K48链接的K315位点的多-ubiquitination来增强其稳定性.
- 在胃癌中,USP12表达与生存率差和YAP点基因活性相关.
结论:
- USP12是胃癌中Hippo/YAP信号通路的新型调节者.
- 通过稳定YAP,USP12促进胃癌的进展.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
