遗传学是一个遗传学.
分子生物学分子生物学

背景情况:

子宫内膜癌是一种常见的女性生殖系统恶性瘤,受到突变和拷贝数变异 (CNV) 的影响.
代表基因增加或损失的CNV越来越被认为是癌症发展的关键因素.

研究的目的:

探索 CNVs 对患者分层和预后预测的临床适用性.

主要方法:

在过去的30年里,PubMed出版物的文献分析.
临床信息的注释,包括组织学/分子亚型,CNV识别技术,位置和涉及的基因.

主要成果:

特定的CNV与肌肉膜侵袭,淋巴结转移,先进的FIGO阶段,高等级,药物反应和癌症进展相关.
I型子宫内膜癌显示较少的CNVs (主要是8q,1q),而II型,高等级和晚期癌症则是具有更多 CNVs的无细胞体.
增加的CNV数量,特别是像CCNE1,ERBB2,KRAS,MYC和PIK3CA这样的瘤基因的放大,与更差的预后有关.
即使在同一亚型内,CNV也存在显著的变异性,这表明改善患者分层的潜力.

结论:

CNV与子宫内膜癌的进展有关,可能有助于更准确的预后预测.
需要进一步的研究,特别是将CNV与分子亚型和药物反应相关联,以使临床应用成为可能.

Comparing Copy Number Variations and SNPs

Comparing Copy Number Variations and SNPs

Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
