遺伝子研究の概要
Tnmd, also known as tenomodulin, is a type II transmembrane glycoprotein encoding gene mapped to the X chromosome. It plays a crucial role in regulating tendon growth, acts as an efficient marker of tenocyte differentiation, and is involved in tenocyte proliferation, tendon development, and angiogenesis inhibition. It also participates in processes like cell adhesion, cell morphology determination, cell aging, and bone mineral density regulation [4].
A case-control study of 356 Han Chinese pregnant women found that the polymorphism of TNMD rs4828038 might be associated with the risk of late-onset preeclampsia, suggesting it could be a target site for genetic diagnosis and therapy [1]. In a rat model of rotator cuff rupture, secretome-hMSCs treatment improved tendon repair by upregulating TNMD expression [2]. Gene transfection of Tnmd in rat bone tissue regeneration inhibited bone formation, with the effect depending on the non-viral gene transfection vector [3]. Single-cell RNA sequencing of arrhythmogenic right ventricular cardiomyopathy (ARVC) patients showed that the right ventricle was enriched with TNMD+ fibroblasts [5]. In in vitro angiogenesis studies, TNMD had a stronger inhibitory effect on tube formation than ranibizumab [6]. Also, activation of Wnt/β-catenin signaling suppressed Tnmd expression in rat tendon-derived cells [7], while stretch-induced Tnmd expression promoted tenocyte migration via F-actin and chromatin remodeling [8].
In summary, Tnmd is essential for tendon-related functions, angiogenesis regulation, and may be involved in diseases such as preeclampsia and ARVC. Studies using animal models and in vitro experiments have revealed its role in various biological processes, providing insights into potential therapeutic targets and mechanisms for related diseases.
