まとめ
二分脊椎研究において、硬膜組織が入手できない場合に、全血および口腔スワブがDNAメチル化研究の代理組織として有望であることが示された。これは神経管閉鎖不全症のエピジェネティクス研究に役立つ。
科学分野:
- エピジェネティクス; ヒト遺伝学; 発達生物学
背景:
- 二分脊椎などの神経管閉鎖不全症は、DNAメチル化のようなエピジェネティックメカニズムの影響を受ける。; 二分脊椎によって影響を受ける神経系組織におけるDNAメチル化プロファイルに関するヒトでの研究は限られている。
研究 の 目的:
- 二分脊椎を有する乳児の硬膜組織におけるDNAメチル化プロファイルを評価する。; 二分脊椎研究におけるDNAメチル化分析の潜在的な代理組織として、全血および口腔スワブを評価する。
主な方法:
- 二分脊椎を有する27人の乳児から採取した硬膜組織、全血、口腔スワブのDNAメチル化を測定した。; DNAメチル化プロファイリングには、Illumina Infinium MethylationEPIC BeadChipアレイを使用した。
主要な成果:
- 硬膜組織と、全血(1555個の関連)および口腔スワブ(920個の関連)の両方との間で、DNAメチル化の有意な相関が見られた。; FDR調整後、CpG部位のかなりの割合で、硬膜組織と全血(33%)または口腔スワブ(27%)との間で有意な差次的メチル化を示さなかった。
結論:
- 硬膜組織が入手できない場合、DNAメチル化研究において全血および口腔スワブは硬膜組織の実行可能な代理として機能することができる。; 神経管閉鎖不全症の病因におけるエピジェネティック要因をさらに調査し、これらの所見を検証するためには、より大規模なコホートによるさらなる研究が必要である。

Cells with similar structure and function are grouped into tissues. A group of tissues with a specialized function is called an organ. There are four main types of tissue in vertebrates: epithelial, connective, muscle, and nervous.

Tissues

Tissues are a group of cells that share a common embryonic origin. Microscopic observation reveals that the cells in a tissue share morphological features and are arranged in an orderly pattern to perform specific functions. From an evolutionary perspective, tissues appear in more complex organisms. Although there are many types of cells in the human body, they are organized into four broad categories of tissues: epithelial, connective, muscle, and nervous. Each of these categories is...

Plant Cells and Tissues
65.8K
Plant tissues are collections of similar cells performing related functions. Different plant tissues will have their own specialized roles and can be combined with other tissues to form organs such as flowers, fruit, stem, and leaves. Two major types of plant tissue include meristematic and permanent tissue.

Tissue Membranes
8.4K
A tissue membrane is a thin layer of cells that covers the outside of the body, the organs, internal passageways that lead to the exterior of the body, and the lining of the moveable joint cavities. There are two basic types of tissue membranes— connective tissue and epithelial membranes.
Connective Tissue Membranes
The connective tissue membrane is formed solely from connective tissue. These membranes encapsulate organs, such as the kidneys, and line our movable joints. A synovial...

Plants are multicellular eukaryotes with tissue systems made of various cell types that carry out specific functions. Different tissues work together to perform a unique function and form an organ. Organs working together form organ systems. Vascular plants have two distinct organ systems: a shoot system and a root system. The shoot system consists of two portions: the vegetative (non-reproductive) parts of the plant, such as the leaves and the stems, and the reproductive parts of the plant,...
