Members of the Epidermal Growth Factors Receptor family (EGFRs) influence cell growth and proliferation, and are pivotal in all phases of tumor progression. We will use this receptor family as an example with which to develop a ground-breaking new technology to study cellular signaling towards atomic resolution, in situ.

Gadd45 family proteins play a critical role in genomic stability, cell cycle regulation proliferation and apoptosis. Gadd45a is activated by the tumor suppressor gene p53, which is mutated in >50% of human tumors. The lack of GADD45a in mice leads to spontaneous development of an autoimmune disease similar to systemic lupus erythematosus. The molecular mechanisms that cause autoimmunity are poorly understood. Recent evidence suggests that p38 activation is involved in autoimmune development and tumor suppression.

The objective of this project is to overcome current limitations for antibody production that are inherent to the extant immune system of vertebrates. This will be done by creating an all-in-one artificial/synthetic counterpart based exclusively on prokaryotic parts, devices and modules. To this end, ARISYS will exploit design concepts, construction hierarchies and standardization notions that stem from contemporary Synthetic Biology for the assembly and validation of (what we believe is) the most complex artificial biological system ventured thus far.

We propose to develop new chemometric and high-throughput analytical methods to assess the effects of environmental and climate changes on target biological systems which are representative of ecosystems. This project will combine powerful chemometric and analytical high-throughput methodologies with toxicological tests to examine the effects of environmental stressors (like chemical pollution) and of climate change (like temperature, water scarcity or food shortage), on genomic and metabonomic profiles of target biological systems.

The current paradigm of T cell function in the immune response is that T cells recognize antigen through the T cell antigen receptor (TCR) which transduces signals to the cytoplasm by way of cytosolic priming and effector tyrosine kinases. The TCR acts in a monovalent fashion is crosslinked by its antigen/MHC (pMHC) ligand, causing TCR triggering.

In eukaryotes, untranslated regions located at the 3′ end (3’UTRs) of messenger RNAs (mRNAs) have been proved to be key post-transcriptional regulatory elements controlling almost every single biological process. In contrast, in bacteria, most studies regarding post-transcriptional regulation have been mainly focused on specific non-coding RNAs and 5’UTRs, which often carry riboswitches or thermosensors. Remarkably, bacterial 3’UTRs have been largely disregarded and have not been considered as potential regulators. Recently, we found that a 3’UTR modulates biofilm formation in S.

Energy-efficient and environmentally friendly light sources are an essential part of the global strategy to reduce the worldwide electricity consumption. Light-emitting diodes (LEDs) emerge as a key alternative to conventional lighting, due to their high power-conversion efficiency, long lifetime, fast switching, robustness, and compact size. Nonetheless, their implementation in the consumer electronic industry is hampered by the limited control over brightness, colour quality and directionality of LED emission that conventional optical elements relying on geometrical optics provide.

One of the major challenges in modern society is the early diagnosis and treatment of diseases. Cancer is one of the most relevant diseases worldwide because of its incidence, prevalence and mortality. During the past decades, considerable efforts have been devoted to understand the origin of the disease, find early detection methods that could improve the survival rate of cancer patients or develop treatments and devices that could reduce or eradicate cancer.

This project aims to reformulate and generalize standard theories of human health and mortality. It proposes new formal models and a systematic agenda to empirically test hypotheses that link developmental biology, epigenetics and adult human illness, disability and mortality. We seek to break new ground developing innovative formal models for illnesses and mortality, testing new hypotheses about the evolution of human health and, to the extent permitted by findings, reformulating standard theories to make them applicable to a less restrictive segment of populations than they are now.

This project will identify the principles governing genome replication in relation to the chromatin landscape and how they impact on plant organ growth. The results will provide the basis to design novel strategies to improve plant growth performance.
