- 分子生物学分子生物学
背景情况:
- 婴儿血瘤 (IH) 是一种常见的血管瘤,具有增殖和回归阶段.
- 一个关键的RNA修饰N6-甲基氨酸 (m6A) 甲基化,影响瘤发育,但其在IH中的作用尚不清楚.
研究的目的:

Epigenetic Regulation
3.7K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.
