在瘤学瘤学.
分子生物学分子生物学
表观遗传学在表观遗传学中,表观遗传学是指表观遗传学.

背景情况:

埃普斯坦-巴尔病毒 (EBV) 相关的胃癌 (EBVaGC) 是一个独特的亚型,具有独特的分子特征.
加斯德明E (GSDME) 是热的关键调解者,这是一个被编程的细胞死亡途径.

研究的目的:

调查EBVaGC中GSDME的调节和功能.
了解EBV诱导的表观遗传修饰在GSDME表达和细胞死亡信号传递中的作用.

主要方法:

对GSDME表达的癌症基因组图谱 (TCGA) 数据的分析.
细胞系实验涉及EBV感染,DNA甲基化分析和用5-azacytidine和paclitaxel (PTX) 治疗.
评估caspase-3激活,GSDME裂变,乳酸脱酶 (LDH) 释放,以及火性形态.

主要成果:

在胃癌中,EBV感染通过促进剂高甲基化选择性地抑制了GSDME的表达.
在PTX治疗后,EBV阳性细胞显示了增强的caspase-3激活和GSDME裂变,导致热.
GSDME过度表达放大了PTX诱导的热,而敲击或caspase-3抑制抑制了它.

Abnormal Proliferation

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Gastritis-II: Pathophysiology

Gastritis-II: Pathophysiology

Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
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...
