科学领域:
- 在瘤学瘤学.
- 遗传学 是一个遗传学.
- 基因组医学是基因组医学.
背景情况:
- 一名60多岁的患者呈现出阳性便隐性血液测试,导致发现多种晚期结肠直肠癌.
- 最初的治疗包括分总切除术和辅助化疗 (CAPOX疗法).
研究的目的:
- 突出考虑多种恶性瘤患者遗传性癌症综合征的重要性.
- 展示综合基因组分析和基因组医学在指导治疗决策中的临床实用性.
主要方法:
- 结肠镜检查显示了多种晚期结肠直肠癌.
- 进行了亚总切除术和CAPOX化疗.
- 综合基因组分析 (CGP) 和下一代测序 (NGS) 确定了一种MLH1致病变体,诊断出林奇综合征.

01:12Loss of Tumor Suppressor Gene Functions
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...

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.
Such genes that act...
