Outline Activities
Sasaki's research interest is epigenetics and epigenomics in mammals. Epigenetics refers to the regulation of gene activity based on modifications of chromatin: it stably maintains cellular identity (differentiation state) and serves as a cell memory. The epigenetic profile of a cell is called the epigenome, and characterization of the epigenomes of various cells and their regulation is thought to be the key to understanding of cell reprogramming and cancer formation. Sasaki investigates the regulatory mechanisms of the epigenome in mammals and their relevance to development, disease, phenotypic variation and evolution. He particularly focuses on genomic imprinting, which is a good model system to study epigenomic regulation in mammals. He was a program leader of a Grant-in Aid for Scientific Research on Priority Areas supported by the MEXT from 2007 to 2012 and is a leader of an CREST project supported by the JST and AMED from 2013 to 2018. Sasaki teaches molecular biology, genetics, and epigenetics and supervise many graduate students. He was on newspapers and TV programs many times. He was awarded a Japanese Society of Human Genetics Award and a Japanese Society of Genetics Kihara Award. He also received a Purple Ribbon Medal of honor in 2015.
