概括

这项研究研究了血清microRNAs作为非功能性垂体腺瘤 (NFPA) 和前性腺瘤的潜在生物标志物. 研究人员发现,虽然NFPA的总微RNA水平较低,但特定的微RNA不是这些垂体瘤的有效非侵入性生物标志物.

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:

垂体腺瘤 (PAs) 是常见的瘤,非功能性垂体腺瘤 (NFPAs) 和前性腺瘤是重要的亚型.
准确和非侵入性诊断生物标志物对于管理PAs至关重要,减少了对侵入性程序的需求.
微RNAs (miRNAs) 正在成为潜在的生物标志物,因为它们在血清等体液中的稳定性.

研究的目的:

在患有侵入性NFPA和前乳腺瘤的患者中评估特定血清miRNAs (hsa-miR-16-5p,hsa-miR-143-3p,hsa-miR-423-5p,hsa-miR-137-3p,hsa-miR-489-5p,hsa-miR-520-3p,hsa-miR-486-5p和hsa-miR-200a-3p) 的诊断潜力.
为了确定是否选择的miRNA表达水平与瘤类型或侵入性相关.

主要方法:

血清样本从62名NFPA患者和18名巨乳细胞瘤患者中收集.
使用TaqMan MicroRNA试验进行了微RNA分离和表达概况.
进行了统计分析,包括ROC曲线分析,以评估诊断效用和相关性.

主要成果:

与对照组相比,NFPA的总微RNA度明显较低 (p=0.0419).
ROC分析表明,对于总体miRNA水平 (AUC=0.629,p=0.052) 有潜在的,尽管有限的预测价值.
在单个miRNAs (hsa-miR-143-3p,hsa-miR-16-5p,hsa-miR-423-5p) 的表达与瘤类型或侵入性之间没有发现显著的相关性.

结论:

尽管总微RNA水平有显著差异,但研究的特定miRNAs (hsa-miR-16-5p,hsa-miR-143-3p,hsa-miR-423-5p) 不适合作为侵入性NFPA和前乳腺瘤的非侵入性生物标志物.
可能需要进一步的研究来确定更具体和可靠的miRNA生物标志物用于垂体腺瘤.

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...

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...

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...

Abnormal Proliferation

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Experimental RNAi

Experimental RNAi

RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...
