まとめ
尿中の血管内皮増殖因子（VEGF）-165b mRNAは、ファブリー病（FD）における腎障害の指標となる可能性がある。発現が高いほどERT期間が長いことと相関し、FD腎症における治療効果の可能性を示唆する。
科学分野:
- 腎臓病学
- 遺伝学
- 分子生物学
背景:
- 血管内皮増殖因子（VEGF）はファブリー病（FD）の腎障害に関与している。
- VEGF-Aは足細胞によって産生され、VEGF-A165bアイソフォームは腎疾患において保護効果を示す。
- 以前の研究では、若年FD患者におけるVEGFレベルの上昇と、動物モデルにおける過剰発現が示唆されている。
主な方法:
- 横断研究デザイン。
- 尿中mRNAの単離とRT-qPCRによる定量。
- 年齢別に層別化された24人のFD患者と24人の健常対照群を含めた。
結論:
- ファブリー病腎症における腎障害への応答として、尿中VEGF-165b mRNAの上昇が示唆される。
- ERTの期間のみが、VEGF-165b mRNAレベルの上昇と相関する唯一の要因である。
- ERT期間が長いことはFD関連の腎障害の軽減を示す可能性があるが、より大規模なサンプルサイズでのさらなる研究が必要である。

02:51mRNA Stability and Gene Expression
6.7K
The structure and stability of mRNA molecules regulates gene expression, as mRNAs are a key step in the pathway from gene to protein. In eukaryotes, the half-life of mRNA varies from a few minutes up to several days. mRNA stability is essential in growth and development. The absence of the proteins regulating its stability, such as tristetraprolin in mice, can cause systemic issues, including bone marrow overgrowth, inflammation, and autoimmunity.

492
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

02:22Regulated mRNA Transport
7.0K
In eukaryotes, transcription and translation are compartmentalized; an mRNA is first synthesized in the nucleus and then selectively transported to the cytoplasm for protein synthesis. Before transport, a pre-mRNA undergoes several steps of post-transcriptional modifications including splicing, 5' capping, and the addition of a poly-adenine tail. Various proteins bind to the pre-mRNA during these modifications. The mRNA transport takes place with the help of multiple proteins playing...

In eukaryotic cells, transcripts made by RNA polymerase are modified and processed before exiting the nucleus. Unprocessed RNA is called precursor mRNA or pre-mRNA to distinguish it from mature mRNA.
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a “cap” to the 5’ end of the growing transcript. In this process, a 5’ phosphate is replaced by modified guanosine that has a methyl group attached to it (7-Methyl...

02:31Nuclear Export of mRNA
8.8K
Before mRNAs are exported to the cytoplasm, it is crucial to check each mRNA for structural and functional integrity. Eukaryotic cells use several different mechanisms, collectively known as mRNA surveillance, to look for irregularities in mRNAs. Irregular or aberrant mRNA are rapidly degraded by various enzymes. If a defective mRNA escapes the surveillance, it would be translated into a protein which would either be non-functional or not function properly. One of the primary irregularities in...
