| 1 | 染色体易位-胚胎植入前诊断的研究进展显示文摘染色体易位携带者有较高的发生不良妊娠结局的风险,主要源自高概率的非均衡配子。对于染色体易位的携带者,进行胚胎植入前遗传学诊断(preimplantation genetic diagnosis,PGD)可以改善妊娠结局。目前,临床应用的非平衡易位诊断的方法主要有比较基因组杂交微阵列(comparative genomic hybridization array,array CGH)、单核苷酸多态性微阵列(single nucleotide polymorphism array,SNP array)和二代测序(next generation sequencing,NGS);荧光原位杂交(fluorescence in situ hybridization,FISH),能够区分平衡易位和正常胚胎,可能实现的技术有NGS。此外,平衡易位的诊断是否有必要开展尚存在争议。 | 范俊梅 Cram David 刘忠宇 李娜 姚元庆 | 2015 | 生殖与避孕2015，35，6： | 2 |
| 2 | Low-depth whole genome sequencing reveals copy number variations associated with higher pathologic grading and more aggressive subtypes of lung non-mucinous adenocarcinoma显示文摘Objective:Histology grade,subtypes and TNM stage of lung adenocarcinomas are useful predictors of prognosis and survival.The aim of the study was to investigate the relationship between chromosomal instability,morphological subtypes and the grading system used in lung non-mucinous adenocarcinoma(LNMA).Methods:We developed a whole genome copy number variation(WGCNV)scoring system and applied next generation sequencing to evaluate CNVs present in 91 LNMA tumor samples.Results:Higher histological grades,aggressive subtypes and more advanced TNM staging were associated with an increased WGCNV score,particularly in CNV regions enriched for tumor suppressor genes and oncogenes.In addition,we demonstrate that 24-chromosome CNV profiling can be performed reliably from specific cell types(<100 cells)isolated by sample laser capture microdissection.Conclusions:Our findings suggest that the WGCNV scoring system we developed may have potential value as an adjunct test for predicting the prognosis of patients diagnosed with LNMA. | Zheng Wang Lin Zhang Lei He Di Cui Chenglong Liu Liangyu Yin Min Zhang Lei Jiang Yuyan Gong Wang Wu Bi Liu Xiaoyu Li David S Cram Dongge Liu | 2020 | Chinese Journal of Cancer Research2020，32，3： | 1 |
