背景情况:
- 乳腺癌 (BC) 仍然是全球癌症死亡的主要原因,需要新的诊断和预后工具.
- 循环微RNAs (miRNAs) 是癌症中各种临床应用的可访问生物标志物.
- 目前的BC管理需要改进风险识别,治疗优化和监测耐药性的方法.
研究的目的:
- 在乳腺癌患者中研究BRCA突变与特定失调miRNAs (miR-21,miR-155,miR-126,miR-200c) 的表达之间的关联.
- 探索miRNA表达特征与乳腺癌亚型和疾病状态之间的相关性.
主要方法:
- 在乳腺癌患者样本中分析miRNA表达水平 (miR-21,miR-155,miR-126,miR-200c).
- 对miRNA表达与乳腺癌亚型,疾病状态和BRCA突变存在的相关性分析.
主要成果:
- 观察到特定miRNAs的表达状态和不同的乳腺癌亚型之间存在显著的相关性.

01:22MicroRNAs
3.0K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

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,...
