- 细胞遗传学研究,包括型和光 in situ 杂交 (FISH),长期以来对于检测癌症染色体异常至关重要.
- 技术进步引入了染色体微阵列 (CMA) 和下一代测序 (NGS),揭示了传统细胞遗传学以前无法检测到的分子标记.
- 尽管高通量分子技术的兴起,传统的细胞遗传学继续在白血病诊断中发挥重要作用.
研究的目的:
- 审查传统细胞遗传学和FISH在血液性恶性瘤中的临床效用.
- 突出突出细胞遗传技术的优势,这些技术补充了新的分子技术.
- 讨论包括CMA,光学基因组映射 (OGM) 和NGS在内的综合基因组测试如何改善癌症中可操作目标的检测.
主要方法:
- 在血液恶性瘤中对常规细胞遗传学 (型,染色体分析) 和光在位杂交 (FISH) 的审查.
- 讨论染色体微阵列 (CMA),光学基因组映射 (OGM) 和下一代测序 (NGS) 用于检测基因组异常.
- 探索用于恶性瘤评估的综合基因组测试方法.
主要成果:
- 传统的细胞遗传学和FISH仍然对诊断和评估白血病至关重要,提供了独特的见解,目前的高通量方法无法完全复制.
- CMA,OGM和NGS检测到超出传统细胞遗传学的分辨率的亚微观和复杂的基因组变化.
- 结合细胞遗传学和广泛分子检测的综合方法可以提高恶性瘤中可操作的标和变体的检测.
结论:
- 细胞遗传学研究在血液性恶性瘤中具有显著的临床价值,特别是在白血病诊断中.
- 像NGS和CMA这样的先进分子技术提供了互补的信息,揭示了更广泛的基因组改变谱.
- 癌症基因组学的未来在于将单细胞细胞遗传测试与全面的分子分析进行整合,以获得最佳的患者护理.

Cancer-Critical Genes I: Proto-oncogenes
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.
