概括

在很大一部分上皮卵巢癌中,BRCA1蛋白表达被改变. 这项研究没有发现与患者年龄,瘤等级或组织学有任何关联,但需要进一步研究以探索生存影响.

科学领域:

在瘤学瘤学.
分子生物学分子生物学
遗传学是一个遗传学.

背景情况:

在上皮卵巢癌 (EOC) 中的BRCA1基因功能障碍源于生殖系/体质突变和促进物甲基化.
在EOC中失去BRCA1蛋白表达具有显著的治疗和预后影响.
了解BRCA1表达模式对于EOC管理至关重要.

研究的目的:

为了确定表皮卵巢癌组织中的BRCA1蛋白表达水平.
研究EBC中的BRCA1表达和临床病理学特征之间的关联.

主要方法:

使用嵌入式 EOC 组织进行横截面实验室研究 (2010 年 1 月 - 2018 年 8 月).
通过血素和乙素 (H&E) 染色进行组织学确认.
用MS110抗体检测BRCA1蛋白质的免疫组织化学 (IHC).
皮尔森的千平方测试用于统计分析.

主要成果:

分析了104例EOC病例;平均年龄为48.7岁.
血清性瘤占主导地位 (74.0%),其中大多数是高度的 (75.3%).
在33.7%的病例中观察到BRCA1蛋白表达的丧失.
在BRCA1表达和年龄,瘤等级或组织学亚型之间没有发现显著的关联.

结论:

改变的BRCA1表达在上皮卵巢癌组织中普遍存在.
目前的发现表明与患者年龄,组织学或瘤等级没有相关性.
需要进一步的研究来阐明BRCA1表达对EOC患者存活时间的影响.

The Retinoblastoma Gene

The Retinoblastoma Gene

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,...

mTOR Signaling and Cancer Progression

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...
