Meeting our Makers: Uncovering the cis-regulatory activity of transposable elements using statistical learning

The adaptation of organisms to their environment depends on the innovative potential inherent to genetic variation. In complex organisms such as mammals, processes like development and immunity require tight gene regulation. Complex forms emerge more often ...

Modeling, analysis, and design of complex biological networks

Mohammadomid Oftadeh

Automating experimental procedures has resulted in an unprecedented increase in the volume of generated data, which, in turn, has caused an accumulation of unprocessed data. As a result, the need to develop tools to analyze data systematically has been ris ...

A systematic CRISPR approach to understanding the role of Drosophila antimicrobial peptides in immunity in vivo

Mark Austin Hanson

Antimicrobial peptides (AMPs) are host-encoded antibiotics that combat invading microbes. These short immune effectors are conserved in plants, animals, and fungi. Early work showed that AMPs killed bacteria in generalist fashions in vitro: i.e. AMPs that ...

Method for determining cancer invasiveness and patient prognosis

Douglas Hanahan, Leanne Li

A method for determining the prognosis for survival of a patient having cancer is disclosed, said cancer being altered (i.e. highly activated or alternatively inactive/inhibited) in the NMDAR signalling pathway, said method comprising determining the expre ...

Memory and relatedness of transcriptional activity in mammalian cell lineages

Felix Naef, David Michael Suter, Nicholas Edward Phillips, Aleksandra Mandic, Saeed Omidi Klishami

Phenotypically identical mammalian cells often display considerable variability in transcript levels of individual genes. How transcriptional activity propagates in cell lineages, and how this varies across genes is poorly understood. Here we combine live- ...

Protein Engineering Tools to Explore the Function of Protein Post-Translational Modifications for Chromatin and Microtubule Cytoskeletal Biology

Ninad Dilip Agashe

Protein post-translational modifications (PTMs) play a crucial role in expanding the protein diversity and are one of the major mechanisms through which cells respond to ever changing environmental cues. The function of two of the most important cellular c ...

Rhythmic and clock-dependent chromatin loops regulate circadian gene expression

Jérôme Mermet

In mammals the circadian clock drives daily behavioural and physiological changes that resonate with environmental cues, which can be observed, for example, in the intricate timing of rest during the night and activity during the day in humans. The circadi ...

Towards artificial methanogenesis: biosynthesis of the [Fe]-hydrogenase cofactor and characterization of the semisynthetic hydrogenase

Xile Hu, Tao Xu, Lichen Bai

The greenhouse gas and energy carrier methane is produced on Earth mainly by methanogenic archaea. In the hydrogenotrophic methanogenic pathway the reduction of one CO2 to one methane molecule requires four molecules of H-2 containing eight electrons. Four ...

Single-molecule kinetic analysis of HP1-chromatin binding reveals a dynamic network of histone modification and DNA interactions

Vassily Hatzimanikatis, Georg Fantner, Beat Fierz, Sandrine Madeleine Suzanne Georgeon, Daniel Robert Weilandt, Oliver Hantschel, Louise Catherine Bryan, Pascal Damian Odermatt, Sinan Kilic, Andreas Linus Bachmann, Carolin Christine Lechner

Chromatin recruitment of effector proteins involved in gene regulation depends on multivalent interaction with histone post-translational modifications (PTMs) and structural features of the chromatin fiber. Due to the complex interactions involved, it is c ...

Genetically encoded multivalent sensors to detect bivalent epigenetic modifications in living stem cells

Aurore Marie-France Delachat

Eukaryotic DNA is organized in the form of chromatin whose basic unit is the nucleosome. The four core histones forming the nucleosome, H2A, H2B, H3 and H4 can be highly post-translationally modified, especially on their N-terminal tail protruding from the ...

Identification of HcgC as a SAM-Dependent Pyridinol Methyltransferase in [Fe]-Hydrogenase Cofactor Biosynthesis

Xile Hu, Tao Xu, Lichen Bai

Previous retrosynthetic and isotope-labeling studies have indicated that biosynthesis of the iron guanylylpyridinol (FeGP) cofactor of [Fe]-hydrogenase requires a methyltransferase. This hypothetical enzyme covalently attaches the methyl group at the 3-pos ...

Integrating gene synthesis and microfluidic protein analysis for rapid protein engineering

Sebastian Maerkl, Ekaterina Emilova Petrova, Bruno Emanuel Ferreira De Sousa Correia, Matthew Christopher Blackburn

The capability to rapidly design proteins with novel functions will have a significant impact on medicine, biotechnology and synthetic biology. Synthetic genes are becoming a commodity, but integrated approaches have yet to be developed that take full adva ...

A Systems Approach to Identify Genetic and Environmental Regulators of Metabolism

Evan Graehl Williams

For more than a century, it has been recognized that our genetic inheritance and our environment interact to shape who we are and how we act (nature vs. nurture ), and the study of genetics has allowed us to explain why traits can vary dramatically betwee ...

Structure and properties of the C-terminal beta-helical domain of VgrG protein from Escherichia coli O157

Petr Leiman

The bacterial Type 6 secretion system (T6SS) translocates protein toxins (also called effectors) from the cytosol of a T6SS-carrying cell to a target cell by a syringe-like supramolecular complex resembling a contractile tail of bacteriophages. Valine-glyc ...

Inferring gene expression from ribosomal promoter sequences, a crowdsourcing approach

The Gene Promoter Expression Prediction challenge consisted of predicting gene expression from promoter sequences in a previously unknown experimentally generated data set. The challenge was presented to the community in the framework of the sixth Dialogue ...

Isolation and Characterisation of Regulators of the Septation Initiation Network Regulators in Fission Yeast

Anupama Goyal

The septation initiation network (SIN) in Schizosaccharomyces pombe regulates cytokinesis. Cdc7p encodes the first kinase in the core SIN pathway. In this study, I performed a genetic screen to identify novel regulators of the SIN pathway by isolating spon ...

ESAT-6 secretion-independent impact of ESX-1 genes espF and espG1 on virulence of Mycobacterium tuberculosis

Stewart Cole, Jeffrey Chen

The pathogenesis of Mycobacterium tuberculosis largely depends on the secretion of the 6-kD early secreted antigenic target ESAT-6 (EsxA) and the 10-kD culture filtrate protein CFP-10 (EsxB) via the ESX-1/typeVII secretion system. Although gene products fr ...
