概括
低ERBB2表达 (ERBB2-低) 的乳腺癌 (BC) 可能与ERBB2-负的BC不同. 低ERBB2瘤,特别是荷尔蒙受体阴性瘤,与ERBB2阴性瘤相比,显示出更好的生存结果.
科学领域:
- 在瘤学瘤学.
- 病理学 病理学 病理学
- 流行病学 流行病学
背景情况:
- 区分具有低ERBB2表达 (ERBB2-低) 的乳腺癌 (BC) 与ERBB2-负的BC,对于理解不同的临床行为至关重要.
- 之前的研究没有明确地将ERBB2-low BC定义为一个独特的实体.
研究的目的:
- 为了比较ERBB2-低BC的临床,病理和流行病学特征与ERBB2-负BC在一个大,多样化的群体中.
- 要确定ERBB2-low BC是否代表一个独特的生物和临床实体.
主要方法:
- 分析了从前性途径研究 (2006-2013) 中对2200名BC妇女的队列研究.
- ERBB2-低被定义为免疫组织化学得分为1+或2+,而ERBB2-负被定义为0+.
- 在ERBB2-低和ERBB2-阴性组之间比较了生存结果 (总生存,无复发生存,BC特异性死亡率),按激素受体状态和瘤透性淋巴细胞 (TIL) 分层.
主要成果:
- 在57.2%的队列中发现了ERBB2-低瘤.
- 在荷尔蒙受体阴性亚组中,ERBB2-低BC显示出与ERBB2-阴性BC相比显著更好的整体存活率,无复发存活率和BC特异性死亡率.
- 在ERBB2-低瘤中,较高的TIL与改善的生存结果相关.
结论:

02:38Mitogens and the Cell Cycle
6.5K
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

01:20The Retinoblastoma Gene
4.1K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

2.1K
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...

01:17Role of ER in the Secretory Pathway
5.4K
Eukaryotic cells have a special pathway that enables communication between various intracellular membrane-bound compartments and also with the extracellular environment. This pathway is termed as the secretory pathway.
Components of the secretory pathway
About a third of proteins synthesized in the cell are sorted via the secretory route. They shuffle between different compartments in membrane-bound vesicles until they reach their final destination. The main intracellular compartments involved...
