概括

已知的子宫内膜癌 (EC) 风险因素,如平价影响健康女性的基因表达,但不影响后来被诊断出EC的女性. 这表明,与无癌症个体的平价相关的终身基因表达变化.

科学领域:

基因组学就是基因组学.
癌症研究癌症研究
流行病学流行病学

背景情况:

子宫内膜癌 (EC) 的发病率正在上升,需要新的预防策略.
了解诊断前的遗传变化对于预测建模至关重要.
已确定的EC风险因素包括性别平等,月经,咖啡,BMI,更年期年龄和口服避孕药的使用.

研究的目的:

调查已知的子宫内膜癌风险因素是否会影响外周血液基因表达.
为了确定EC风险因素和女性基因表达特征之间的关联.

主要方法:

从一个庞大的前性队列 (16.5万名女性) 中选择了EC风险因素.
在NOWAC后基因组的嵌套病例控制研究 (79对) 中使用BeadChip微阵列技术.
进行基因组丰富分析 (GSEA).

主要成果:

在EC病例和对照组之间没有发现总体基因表达差异.
同等性状态的变化与对照组中的1379个基因表达有关,但在EC病例中并非如此.
体重指数 (BMI) 的变化与对照组的27个基因表达相关,但在EC病例中并非如此.
GSEA揭示了2407个显著丰富的基因组,与无癌症女性的平价相关.

结论:

增加的平价对那些没有患上癌症的女性的外周血液基因表达有终身影响.
无论是多对还是高BMI,都没有改变后来被诊断为子宫内膜癌的女性的基因表达.
这些发现突出了与无癌症与癌前个体风险因素相关的独特基因表达模式.

Genome-wide Association Studies-GWAS

Genome-wide Association Studies-GWAS

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.
GWAS does not require the identification of the target gene involved in...

Pharmacogenomics: Identification of New Drug Targets

Pharmacogenomics: Identification of New Drug Targets

Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...
