概括
这项研究确定了PKMYT1和GAS5等关键基因作为乳头甲状腺癌 (PTC) 的可靠诊断标志物,并开发了患者生存的预后模型. 这些发现为PTC致癌和临床管理提供了新的见解.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 生物信息学是一种生物信息学.
背景情况:
- 乳头甲状腺癌 (PTC) 的病因是复杂的,了解其分子驱动因素至关重要.
- 竞争性内源性RNA (ceRNA) 假说提供了一个探索致癌机制的框架.
- 确定所有PTC阶段的可靠诊断和预后指标是一个重要的临床需求.
研究的目的:
- 构建一个新的ceRNA网络和相关的调节网络 (DE-TF) 治疗乳头甲状腺癌.
- 在所有阶段确定可靠的PTC诊断和预后生物标志物.
- 在PTC中调查基因表达与血水平之间的关联.
主要方法:

The Nucleolus
10.2K
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,...

Synthesis and Regulation of Thyroid Hormones
7.1K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...
