まとめ
INK4ロカス (ANRIL) のアンチセンセスの非コーディングRNAの遺伝的変異は胃がん (GC) のリスクと関連しています. ANRILにおける特定の単一ヌクレオチドポリモルフィズム (SNPs) は,韓国人集団におけるGC発達の変化と関連していた.
科学分野:
- 遺伝学
- 腫瘍学
- 分子生物学
背景:
- 長いノンコーディングRNA (lncRNA) は,がん発症における役割としてますます認識されています.
- ANRIL のような lncRNA の内にある遺伝的変異,特に単一ヌクレオチドポリモルフィズム (SNPs) は,がんのリスクに影響を与える可能性があります.
- ANRIL SNPと胃がん (GC) のリスクとの関連に関する研究は限られている.
研究 の 目的:
- ANRIL遺伝子の特定のSNPと胃がんの発症リスクとの関連を調査する.
- これらのANRIL SNPがリンパ節転移および異なる腫瘍分化を有する患者を含む異なる患者サブグループでGCリスクと関連しているかどうかを評価する.
- 胃がんのバイオマーカーとしてのANRIL SNPの可能性を調査する.
主な方法:
- 韓国人集団の419人のGC患者と348人の健康な対照群を対象に,症例対照試験を実施した.
- ANRIL遺伝子内の6つの選択されたSNPのゲノタイプ化はTaqManアッセイを使用して行われました.
- 年齢と性別を考慮して,調整された確率比率と信頼区間を含む統計的分析を用いて,SNPとGCリスクの関連性を評価した.
主要な成果:
- SNP rs2157719は,支配的なモデルでリンパ節転移陰性サブグループにおけるGCリスクの減少と有意な関連を示した.
- SNP rs1333040は,不分化サブグループにおけるGCのリスク増加と関連していた.
- SNP rs4977574は,リンパ節転移,腫瘍ステージIII,および分化されていない腫瘍を有するサブグループでGCリスクの低下と関連を示した.
結論:
- ANRIL遺伝子の研究されたSNPは,胃がんのリスクと有意に関連しており,GCの発症と進行に役割を果たす可能性があります.
- これらの発見は,特に特定のサブグループにおいて,ANRIL SNPが胃がんのバイオマーカーとして機能する可能性を示唆しています.
- これらの関連性とその臨床的影響を確認するために,より大きな多様な民族集団でのさらなる検証が必要である.

8.9K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

14.1K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.

03:18Non-LTR Retrotransposons
11.9K
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

01:05Single Nucleotide Polymorphisms-SNPs
15.8K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

01:22MicroRNAs
3.1K
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...

9.1K
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...
