概括

ресвератрол可以阻止肺癌细胞激活血小板,这是癌症相关静脉血栓栓塞 (CAT) 的关键因素. 这种天然化合物通过向血小板亡,显示出对治疗肺癌和CAT的前途.

科学领域:

在瘤学瘤学.
血液学血液学血液学
药理学药理学是指药理学的学科.

背景情况:

与癌症相关的静脉血栓塞栓症 (CAT) 是癌症患者的一个重大并发症.
复星在预防肺癌中CAT的作用尚不清楚.
肺腺癌细胞可以诱导血小板激活,有助于高凝固性.

研究的目的:

为了研究复星对肺腺癌诱导的血小板激活的作用.
阐明复星调节血小板激活的机制.
评估resveratrol在肺癌和CAT中的治疗潜力.

主要方法:

在非小细胞肺癌 (NSCLC) 患者的凝血功能分析.
使用A549和易斯肺癌细胞进行体外研究,以评估血小板激活.
复星治疗,西式涂抹,电子显微镜,流细胞计和ELISA.
在携带瘤的小鼠体内研究,以评估瘤生长和血小板功能.

主要成果:

NSCLC患者表现出高凝血状态;肺癌细胞诱导血小板激活.
Ресвератрол减弱了肺癌引起的血小板激活.
复星促进了HMGB1丰富的细胞外囊泡 (EV) 从肺癌细胞中释放,通过增加ROS,脂质过氧化和破坏的囊载体导致血小板铁亡.
在体内,白醇抑制了瘤生长,并抑制了瘤诱导的血小板激活.

结论:

Ресвератрол减轻了与铁亡相关的肺癌诱导的血小板激活.

Receptor Downregulation in MVBs

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that lead to cell proliferation, migration, and differentiation. Overexpression of EGFR stimulates cells to proliferate. Excessive EGFR...
