Project acronym ChemEpigen
Project The chemical understanding of biomolecular recognition in epigenetics
Researcher (PI) Jasmin MECINOVIC
Host Institution (HI) SYDDANSK UNIVERSITET
Call Details Starting Grant (StG), PE5, ERC-2016-STG
Summary The ultimate aim of this ERC project is to provide a comprehensive and complete understanding, at the atomic-level of sophistication, of genuinely important biomolecular recognition processes in epigenetics that play key roles in human health and disease. At the biochemical level, epigenetics refers to mechanisms, such as enzymatic modifications of DNA and posttranslational modifications of the associated histone proteins, that regulate the activity of human genes. The proposed work aims to address epigenetics using the physical-organic chemistry approach that enables the elucidation of the elemental processes with unprecedented molecular/atomic detail. The project will experimentally and computationally examine non-covalent interactions between three essential constituents of the epigenetic biomolecular system, namely epigenetic proteins, histones and water, at the level of short histone peptides, intact histone proteins, the nucleosome assembly and nucleosome arrays. Our programme, built on synergistic thermodynamic, structural and computational studies, aims to unravel i) the underlying chemical origin of methyllysine-containing histones in epigenetics, ii) the chemical basis for the recognition of methylarginine-containing histones in epigenetic processes, and iii) the role of unstructured histone tails in biomolecular recognition, which together form the three main structural elements found in the epigenetic framework. Results from this work will be important from both a fundamental molecular perspective as well as from the biomedical perspective, because proteins involved in epigenetic regulation processes are currently regarded as important targets for numerous therapeutic interventions, most notably for cancer treatment.

Project Radio wave propagation in heterogeneous media: implications on the electronics of Cosmic Neutrino Detectors
Researcher (PI) Alina Mihaela BADESCU
Host Institution (HI) UNIVERSITATEA POLITEHNICA DIN BUCURESTI
Call Details Starting Grant (StG), PE7, ERC-2016-STG
Summary Detection of cosmic neutrinos can answer very important questions related to some extremely energetic yet unexplained astrophysical sources such as: compact binary stars, accreting black holes, supernovae etc., key elements in understanding the evolution and fate of the Universe. Moreover, these particles carry the highest
energies per particle known to man, impossible to achieve in any present or foreseen man made accelerator devices thus their detection can test and probe extreme high energy physics.
One of the newest techniques for measuring high energy cosmic neutrinos regards their radio detection in natural salt mines. A first and essential step is to determine experimentally the radio wave attenuation length in salt mines, and this will represent the main goal of this project. The results shall be used to estimate the implications on the construction of the detector. The outcome of this project may rejuvenate the radio detection in salt technique and be a compelling case for Romanian involvement. The same measurements can be used: to validate and improve previous work on theoretical simulation models of propagation in heterogeneous media –a regime not very well understood (which represents another goal of the project), and to study the behavior of classical antennas in non-conventional media (the third major goal).
The results to be obtained would be immediately relevant in determination of the key parameters that describe a cosmic neutrino detector, its performances and limitations. The events detected by such a telescope will allow identification of individual sources indicating a step forward in “neutrino astronomy”. The extensive propagation and antenna behavior studies in heterogeneous media will be in the direct interest for the scientific community and have a prompt impact in telecommunications theory and industry.
