概括

微RNAs (miRNAs) miR-183-5p和miR-375-5p在甲状腺髓癌 (MTC) 中显示出改变的表达,有助于诊断. 较低的miR-200c-3p表达与增加的MTC临床攻击性相关.

科学领域:

内分泌学在内分泌学.
分子生物学分子生物学
在瘤学瘤学.

背景情况:

状甲状腺癌 (MTC) 诊断依赖于激素水平和TNM分期,但细胞学的准确性有限.
微RNAs (miRNAs) 是新兴的生物标志物,但它们在MTC中的作用需要进一步研究.

研究的目的:

在MTC患者中确定miRNA表达特征.
调查特定miRNAs和MTC临床攻击性之间的关联.

主要方法:

在MTC和25名患者的健康甲状腺组织中分析miRNA表达 (miR-183-5p,miR-375-5p,miR-144-3p,miR-34a-5p,miR-200c-3p).
实时PCR用于基因表达量化.
统计分析包括克鲁斯卡尔-瓦利斯,曼-惠特尼U和斯皮尔曼的 ρ 测试.

主要成果:

在MTC和健康的甲状腺组织之间观察到miR-183-5p和miR-375-5p表达的显著差异 (p = 0.001).
较高的miR-200c-3p表达与更好的无疾病生存率 (DFS) 相关 (ρ = 0.456,p = 0.022).

结论:

miR-183-5p和miR-375-5p的表达可以作为MTC的诊断生物标志物.
减少miR-200c-3p的表达表明MTC中临床攻击性增加.

MicroRNAs

MicroRNAs

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...

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...
