Quantitative mass spectrometry of posttranslational modifications: Keys to confidence

10 Apr 2015
Posttranslational modifications (PTMs) of proteins represent an important level of cellular control. They participate in the efficient transduction of signals and form the basis of long-term cellular memory, allowing cells to adapt to a rapidly changing environment. More than 200 different PTMs have been described that affect many aspects of protein functions, and the importance of these ...

Network-based proteomic approaches reveal the neurodegenerative, neuroprotective and pain-related mechanisms involved after retrograde axonal damage

1 Apr 2015
Neurodegenerative processes are preceded by neuronal dysfunction and synaptic disconnection. Disconnection between spinal motoneuron (MN) soma and synaptic target leads either to a retrograde degenerative process or to a regenerative reaction, depending injury proximity among other factors. Distinguished key events associated with one or other processes may give some clues towards new ...

dSysMap: Exploring the edgetic role of disease mutations

1 Apr 2015
Considering pathological genetic variants within the context of the human interactome network can help understanding the intricate genotype-to-phenotype relationships behind human diseases. It allows, for instance, to distinguish between changes that totally suppress a gene product (i.e. node removal) from the ones that might affect only one of its functions, modulating the way in which the ...

Drug sensitivity in cancer cell lines is not tissue-specific

15 Mar 2015
BACKGROUND: Cancer cell lines have a prominent role in the initial stages of drug discovery, facilitating high-throughput screening of potential drugs. However, their clinical relevance remains controversial. FINDINGS: We assess whether drug sensitivity in cancer cell lines is able to discriminate tissue specificity. We find that cancer-specific drugs do not show higher efficacies in cell lines ...
