SEMINAR SERIES: Gideon Dreyfuss - Speaker in the BIMSB Seminar Series

On July 7, 2015, Gideon Dreyfuss from University of Pennsylvania visited BIMSB. He presented the lecture "An overarching RNA-controlled gene expression mechanism and cancer cell phenotype”.

Gideon, a HHMI investigator and Isaac Norris Professor of Biochemistry and Biophysics has been a key figure in the field of ribonucleoproteins and made important contribution to understanding their role in gene regulation and disease. His group focuses on the RNA-binding proteins that constitute premRNA-RNPs and noncoding small nuclear RNPs, the two key instruments of mRNA processing and gene regulation, whose perturbations underlie numerous diseases. Areas emerging from these studies are being pursued: the SMN complex, the RNA-protein chaperone required for snRNP assembly; and pre-mRNA protection, a crucial step that shapes the transcriptome. Recently, they discovered a crucial gene regulatory mechanism involving U1 snRNP, which protects the nascent transcriptome from destructive pre-mature termination and provides a tool to modulate cells’ response to stimuli and oncogenic phenotype.

Visit of Rahul Satija

On July 3, 2015, Rahul Satija from NYU visited BIMSB and gave a presentation on "Learning the 'metadata' of a cell - statistical methods for single cell genomics".

As a PostDoc at the Broad Institute, Rahul pioneered droplet based single cell sequencing methods and analyses (Shalek & Satija et al. Nature 2013; Shalek & Satija et al. Nature 2014; Macosko et al. Cell 2015). He applied this to zebrafish embryos and reconstructed a high-resolution spatial map of gene expression by computationally clustering thousands of single-cell sequencing data (Satija et al. Nat. Biotech. 2015). Amongst other insights, this approach identified new marker genes.

Rahul demonstrated  the very forefront of method development, applications and analyses of single-cell transcriptome sequencing that he now develops in his own lab and at the New York Genome Center.

CONFERENCE: Berlin Summer Meeting 2015 - Localization of Cellular Processes

From the June 4-6, 2015, the 8th annual Berlin Summer Meeting took place at the Umweltforum in Berlin Friedrichshain. This former church was a spectacular setting for an event that brought computational and experimental biologists together for intense scientific exchange on the "Localization of Cellular Processes".

Internationally renowned researchers spoke on recent developments and new challenges in areas such as the functional organization within the nucleus (e.g. Kerstin Bystriki, University of Toulouse, FR and Ana Pombo, MDC-Berlin, GER), mechanisms and consequences of RNA localization within cells (e.g. Anne Ephrussi, EMBL, GER and Steve Small, NYU, USA),  local translation and protein localization in cellular function and disease (e.g. Joel Richter, U.Mass., USA and Antonella Riccio, MRC-UCL, UK), as well as localized signaling (e.g. Lionel Christiaen, NYU, USA and Sylvia Santos, MRC-CSC, UK).

The impressive keynote presentations were joined by shorter talks selected from submitted abstracts, which allowed further insights into new technologies and approach to understand the complex spatial organization of biological processes. During a lively poster session, younger scientists had a chance to discuss their results with over a hundred participants. The four best posters were awarded with poster prices, kindly sponsored by the Shering Stiftung. Thank you to all who participated and made this a successful, vibrant meeting.

For more information, please visit the Berlin Summer Meeting homepage and keep an eye out for the 9th Berlin Summer Meeting to be held in the summer of 2016!

PUBLICATION: Comprehensive new map helps understanding of gene regulation by the ribonuclease dicer

All the cells in our bodies, be they nerve or kidney cells, blood or skin cells, carry the same genetic information. And yet they all differ considerably. This is because different genes are transcribed in each cell type. In recent years, scientists have found a new class of molecules, so-called “microRNAs”, that play a crucial role in this gene regulation. An enzyme known as Dicer is involved in the formation of these microRNAs. A team of researchers led by Markus Landthaler and Nikolaus Rajewsky at the MDC’s Berlin Institute for Molecular Systems Biology (BIMSB) have recently compiled a comprehensive map of the RNA-binding and processing sites of Dicer, which they published in the journal Cell. Increased understanding of the basic mechanisms governing gene regulation could help in the search for targeted drugs and therapies.

Further information can be found in the MDC's Research Highlights section.

SEMINAR SERIES: Matthias Hentze - Distinguished Speaker in the BIMSB Seminar Series

On the April 21, 2015, we had another highlight in our seminar series as Matthias Hentze, Director at the EMBL Heidelberg and Head of our Scientific Advisory Board, gave a Distinguished Speaker Seminar about “RNA binding proteins, metabolism and a new function of the genome”.

Matthias combines biochemical and systems level approaches to investigate the regulation of mRNAs via RNA-binding proteins and non-coding regulatory RNAs and recently identified all RNA-bindinding proteins in vivo using RNA interactome capture. As some of these RNA-binding proteins are ‘classic' enzymes carrying out housekeeping functions of intermediary metabolism, Matthias proposed the existence of post-transcriptional regulatory networks between intermediary metabolism and gene expression based on RNA, enzyme and metabolite interactions.

PUBLICATION: New Insights on DNA Transcription: Start Region Shown to Be Directional

To bind enzymes that read a gene at the right place, the DNA contains so-called promoters, recognition sequences that are located near the transcription start sites of the genes. Since the advent of high-throughput sequencing technology, which enables the precise investigation of gene expression patterns, scientists had shown that a large percentage of promoters is not unidirectional and that the DNA is read on both opposing strands. Now, in the present study, Professor Uwe Ohler of the Max Delbrück Center for Molecular Medicine (MDC) and Professor James T. Kadonaga of the University of California in San Diego, USA have shown in human cells that a central part of promoters, the core promoter, is intrinsically unidirectional. Thus, transcripts of the opposing DNA strand arise from their own core promoters.

Helmholtz International Fellow Award for long-standing collaborator Professor Amanda Fisher

The British cell biologist Professor Amanda Gay Fisher of Imperial College London (ICL) has been honored with the Helmholtz International Fellow Award for her excellent research. She is one of seven outstanding researchers from abroad who received the award, each of which is endowed with 20,000 euros. Professor Fisher intends in particular to strengthen her existing collaborations with the Berlin Institute of Medical Systems Biology (BIMSB) of the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch. 

In her research, Professor Fisher focuses on gene regulation, a fundamental process of life which controls every biological function, including cell division, cell differentiation and regeneration. Professor Fisher, who started her research career in the 1980s, has earned an international reputation in this field. She is known for her pioneering work on HIV, the AIDS virus, describing the function of several of its genes. She also is an expert in epigenetic gene regulation - a process in which molecular biological information not contained in the DNA regulates which genes are turned on and which genes are kept silent. She also has an expertise in T lymphocyte development (immune cells) and in embryonic stem cells.
