概括
端粒调节基因 (TRG) 的生殖系变异与某些人群的甲状腺癌 (TC) 风险有关. 然而,这项研究在沙特阿拉伯患者中没有发现任何显著的关联,这表明TRG的种族差异.
科学领域:
- 遗传学 是一个遗传学.
- 在瘤学瘤学.
- 分子生物学分子生物学
背景情况:
- 谢尔特林复合体端粒调节基因 (TRG) 的生殖系变异与增加甲状腺癌 (TC) 风险有关.
- 以前的研究,主要来自美国,已经表明TRG变体和TC之间存在联系.
- 在不同的祖先群体中验证对于理解这些变异的全球作用至关重要.
研究的目的:
- 调查沙特阿拉伯人口中端粒调节基因 (TRG) 和甲状腺癌 (TC) 的生殖系变异之间的关联.
- 为了验证或驳斥在不同族群中进行的先前研究的发现.
- 探索TRG变异在这个特定的人口群中的零星和家族TC中的作用.
主要方法:
- 一项涉及189名零星TC患者和来自沙特阿拉伯26个TC受影响家庭的63名个体的横截面研究.
- 来自外围血液的基因组DNA的全外体序列 (WES) 测序.
- 生物信息学分析的重点是识别和表征TRG变体,包括ACD,TERF1和TERT.
主要成果:
- 在189名39名 (20.6%) 间歇性TC患者中,发现了8种TRG变异,包括ACD,TERF1和TERT的变异.
- 在家族TC队列中只发现了两个TRG变体 (一个TERF1,一个ACD).
- 所有已识别的TRG变异被归类为意义不明或可能良性的变异;此前报告的美国TRG变异在这个队列和本地数据库中缺席.
结论:
- 与美国的发现不同,生殖线端粒调节基因 (TRG) 变异似乎不会对沙特阿拉伯人口的甲状腺癌 (TC) 风险产生影响.
- 在TC发育中TRG变异的作用可能是群体特异性的,这突显了在遗传关联研究中种族多样性的重要性.
- 需要对不同种族群体进行进一步的研究,以充分阐明TRG变异对甲状腺癌易感性的贡献.

4.3K
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...

9.4K
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

26.8K
In eukaryotic DNA replication, a single-stranded DNA fragment remains at the end of a chromosome after the removal of the final primer. This section of DNA cannot be replicated in the same manner as the rest of the strand because there is no 3’ end to which the newly synthesized DNA can attach. This non-replicated fragment results in gradual loss of the chromosomal DNA during each cell duplication. Additionally, it can induce a DNA damage response by enzymes that recognize single-stranded...

01:12Loss of Tumor Suppressor Gene Functions
5.8K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

02:30Histone Variants at the Centromere
4.9K
Histone variants are the histone proteins with structural and sequence variations. These variants may be regarded as “mutant” forms that replace their canonical histone counterparts in the nucleosomes. Specific post-translational modifications on the histone variants enable further chromatin complexity and regulate tissue-specific gene expression. The most common histone variants are from histone H2A, H2B, and linker histone H1 families. However, several variants of histone H3...
