■ 癌症的性别差异: |
在各种个体差异中,性别差异是最有趣的研究话题之一,曾经有调查指出,近年来癌症的发病率急速飙升,而其中男性患癌几率要高于女性,但这些调查都是从表面现象进行分析,未能指出其背后的分子机制。
来自MD安德森癌症中心的梁晗等人利用来自癌症基因组图谱(TCGA)的数据,发现一半以上经研究与癌症治疗临床实践有关联的基因,在某些癌症类型中显示出性别偏倚标记。
“我们研究组这几年来一直致力于癌症基因组的比较分析,尤其是跨癌症类型的比较。而这些分析的主要目的是为理解肿瘤的分子基础,从而为精准癌症治疗提供有益的思路。随着TCGA项目的不断深入,我们发现目前的分子比较局限于癌症亚型之间。而男女性别的差异在很多种癌症的发病率,死亡率,和治疗效果都有很大的差异(甚至大于一些亚型的差异),而两者之间的分子差异的研究却少之又少,所以很自然的确立了这样一个课题,”梁晗博士指出。【详细全文】 |

人物简介: |
Dr. Liang received Ph.D. training from the Quantitative and Computational Biology program (home department, Chemistry) at Princeton University, which provides graduate education in the interface of biology, the physical sciences, and computational science. His PhD thesis is about RNA informatics on translation termination and alternative splicing. As a postdoctoral researcher, Dr. Liang completed three years of research on computational and evolutionary genomics at the University of Chicago, where his research was about microRNA regulation and gene duplication. Currently, Dr. Liang's research interests include development of bioinformatics tools for better analyzing cancer genomic data, the pan-cancer genomic analysis, RNA editing, and the evolutionary process of cancer cells. |
