(甲基化) RNA免疫沉以评估RNA结合.

主要成果:

与对照组相比,pterygium组织中的Matrin 3 (MATR3) 表达显著降低.
作为m6A甲基转移酶复合物的组成部分,WTAP在对照组织中与MATR3进行了特定的相互作用,但在pterygium中没有.
WTAP和MATR3之间的结合亲和性在pterygium下调基因的3'未翻译区域 (UTR) 丢失.
证据表明,在pterygium中,MATR3和m6A甲基转移酶复杂相互作用中发生了干扰.

结论:

这项研究发现了MATR3与pterygium中的N6-甲基氨酸甲基转移酶复合体之间的相互作用丧失.
这种被破坏的相互作用可能会影响目标基因的转录,从而有助于pterygium的发展.
对MATR3和m6A修饰通路的进一步研究可能为pterygium提供新的治疗点.

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...

Spreading of Chromatin Modifications

Spreading of Chromatin Modifications

The histone proteins in the nucleosomes are post-translationally modified (PTM) to increase or decrease access to DNA. The commonly observed PTMs are methylation, acetylation, phosphorylation, and ubiquitination of lysine amino acids in the histone H3 tail region. These histone modifications have specific meaning for the cell. Hence, they are called "histone code". The protein complex involved in histone modification is termed as "reader-writer" complex.
