概括
在Sirtuin 6 (SIRT6) 中的单核酸多态 (SNP) 与质瘤风险有关. 在质瘤患者中SIRT6表达的降低表明它有可能成为这种中枢神经系统癌症的预测标记物.
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:
- 质瘤是一种普遍存在的中枢神经系统癌症.
- 赛尔图因6 (SIRT6) 被认为是质瘤中的瘤抑制剂.
- 遗传SIRT6变异与质瘤易感性之间的关联仍然未被探索.
研究的目的:
- 研究SIRT6基因中单核酸多态 (SNPs) 与发展质瘤的风险之间的关系.
- 分析质瘤患者和健康个体中SIRT6的表达水平.
主要方法:
- 在205名质瘤患者和225名对照人群中使用聚合酶链反应-限制片段长度多态 (PCR-RFLP) 来确定SIRT6SNP (rs350843,rs352493,rs11878868) 的基因型.
- 在血样本中通过逆转录量化聚合酶链反应 (RT-qPCR) 量化SIRT6mRNA表达水平.
主要成果:
- 特定的等位基因 (rs350843的A,rs352493的C) 和SIRT6SNP的基因型与质瘤风险的改变显著相关 (P<0.001).
- 与对照组相比,质瘤患者的SIRT6表达显着较低 (P < 0.001),特别是那些具有rs11878868 TT基因型的人.
- SIRT6基因多态性 (rs352493和rs11878868) 成为结质瘤风险的独立预测因素 (P<0.01).
结论:
- SIRT6遗传变异与质瘤易感性有显著的相关性.

17.9K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

15.3K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.

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.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

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...
