- 纤维细胞生长因子受体2 (FGFR2) 基因变异与非非洲人群的乳腺癌风险有关.
- 了解黑人南非人等研究不足的人群中的遗传风险因素对于公平的癌症研究至关重要.
研究的目的:
- 研究FGFR2基因中的四个单核酸多态 (SNPs) 与黑人南非妇女乳腺癌风险的关联.
- 确定在欧洲人群中发现的遗传生物标志物是否与撒哈拉以南非洲人群的乳腺癌风险有关.
主要方法:
- 基因组DNA分析了1001名乳腺癌患者和1006名来自南非黑人队列的对照.

01:05Cancer-Critical Genes II: Tumor Suppressor Genes
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.

01:11Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase
Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...
