About Chuan He
Chuan He is a Chinese-American chemical biologist, and is currently the John T. Wilson Distinguished Service Professor at the University of Chicago, and an Investigator of the Howard Hughes Medical Institute. He is best known for his work in discovering and deciphering reversible RNA methylation in post-transcriptional gene expression regulation. In 2010, He proposed that RNA modifications could be reversible and may have regulatory roles analogous to well-known reversible DNA and protein modifications. He and colleagues subsequently discovered the first RNA demethylase that oxidatively reverses N6-methyladenosine (m6A) methylation in mammalian messenger RNA (mRNA) in 2011. The existence of m6A in mRNA was discovered in 1974 in both eukaryotic and viral mRNAs; however, the biological significance and functional role were not known before He’s work. This methylation is the most abundant internal modification in mammalian mRNA. In 2012, two independent studies reported transcriptome-wide mapping of m6A in mammalian cells and tissues, revealing a unique distribution pattern. He and co-workers identified and characterized the direct reader proteins for m6A, which impact the stability and the translation efficiency of m6A-modified mRNA, elucidating functional roles of mRNA methylation. He’s group also purified the methyltransferase complex that mediates this methylation.
The He laboratory also studies DNA methylation. He invented TAB-seq, a method that can map 5-hydroxymethylcytosine (5hmC) at base-resolution genome-wide, as well as hmC-Seal, a method that covalently labels 5hmC for its detection and profiling. Together with two other research groups, He and co-workers have revealed the DNA N6-methyldeoxyadenosine as a new methylation mark that could affect gene expression in eukaryotes.

Chemical Biology of Nucleic Acids: DNA Origami and Artificial Genetic Switch
The DNA origami method developed for the preparation of fully addressable two-dimensional (2-D) structures has been utilized for the selective positioning of the functional molecules and nanoparticles. We designed ”DNA frame” using the DNA origami method to investigate enzymatic action and DNA structural change. Our group also have been undertaking original research on the molecular recognition of DNA by antitumor antibiotics, and the analysis of atom-specific chemical reaction on DNA. By reconstituting such knowledge, various functionalized sequence-specific DNA binding pyrrole-imidazole polyamides (PIPs) were synthesized as an artificial genetic switch, which can switch on and switch off the gene expression on demand. To extend recognition sequence, we introduce host-guest system to facilitate cooperative binding to target sequence even in cellular condition. In this talk recent progress of DNA origami technology and regulation of the gene expression using designed PIPs will be discussed.

About Floyd E. Romesberg
Dr. Romesberg has managed a research group at The Scripps Research Institute since 1998. His group uses a broad range of techniques, including non-linear optical spectroscopy, organic chemistry, microbiology, and genetics, to study different aspects of evolution. This work has been described in more than 100 peer-reviewed publications and has been funded by the National Institutes of Health, National Science Foundation, Office of Naval Research, and the Defense Advanced Research Projects Agency. Dr. Romesberg is best known for developing unnatural base pairs for the expansion of the genetic alphabet and is also working to develop novel antibiotics, as well as to understand how evolution tailors protein dynamics and how cellular stress and DNA damage induce cell-cycle checkpoint responses and mutations.
Dr. Romesberg is also the scientific founder and a member of the board of directors of Synthorx. Prior to Synthorx, he served as the scientific co-founder and a member of the board of directors of RQx Pharmaceuticals (acquired by Genentech) and Achaogen.

About Timothy Mitchison
Dr. Mitchison is interested in all aspects relating to microtubules, the cytoskeleton, and cell division.
Dr. Mitchison received his Ph.D. in Biochemistry and Biophysics from the University of California, San Francisco. During his PhD work at the University of California, San Francisco with Dr. Marc Kirschner, he discovered dynamic Instability of microtubules, a fundamental aspect of cytoskeleton biology and since then has studied the biochemistry, dynamics and spatial organization of microtubules and actin filaments with a focus on cell division mechanisms. Much of his lab's work in this area is based on live fluorescence imaging and has been at the forefront of the application of novel optical methodologies to living cells.
In 1997 he moved to Harvard Medical School to Co-direct the Institute of Chemistry and Cell Biology, a collaboration between chemists and cell biologists, to develop and apply small molecule screening capabilities in academia. As part of this effort, Dr. Mitchison's developed a strong interest in cancer chemotherapy and in more rational approaches to drug development in general. In 2004 he co-founded a new department, Systems Biology, that aims to bring systematic and quantitative methods to bear on problems in basic cell biology and medicine and in 2011 he helped found the Systems Pharmacology initiative at Harvard Medical School, a major interest area within the department, co-Directed by Peter Sorger and himself.
Dr. Mitchison is the Hasib Sabbagh Professor of Systems Biology, and co-Director of the Initiative in Systems Pharmacology at Harvard Medical School.
