"There is more virus in us than us in us". John Coffin's famous sentence illustrates that particular nucleic acid sequences related to exogenous viruses, called retrotransposons, constitute almost half of the human genome and largely exceeds the amount of ...
Gene transcription is essential for the establishment and the maintenance of long-term memory (LTM) and for long-lasting forms of synaptic plasticity. The molecular mechanisms that control gene transcription in neuronal cells are complex and recruit multip ...
BACKGROUND: Processing by gamma-secretase of many type-I membrane protein substrates triggers signaling cascades by releasing intracellular domains (ICDs) that, following nuclear translocation, modulate the transcription of different genes regulating a div ...
Heritable changes to the transcriptome that are independent to changes in the genome are defined as epigenetics. DNA methylation and posttranslational modifications of histones, such as acetylation/deacetylation and methylation/demethylation of lysine resi ...
BACKGROUND: To understand cancer-related modifications to transcriptional programs requires detailed knowledge about the activation of signal-transduction pathways and gene expression programs. To investigate the mechanisms of target gene regulation by hum ...
rganisms adapt their metabolism to meet ever changing environmental conditions. This metabolic adaptation involves at a cellular level the fine tuning of mitochondrial function, which is mainly under the control of the transcriptional co-activator prolifer ...
Snail-type transcription factors (TFs) are found in numerous metazoan organisms and function in a plethora of cellular and developmental processes including mesoderm and neuronal development, apoptosis and cancer. So far, Snail-type TFs are exclusively kno ...
DNA uptake by polyethylenimine (PEI)-mediated transfection was investigated in Chinese hamster ovary (CHO DG44) cells. Rapid DNA uptake was observed with the maximum occurring during the first 45-60 min after addition of PEI-DNA complexes to cells. With lo ...
Huntington's disease (HD) is an autosomal, dominantly inherited neurodegenerative disorder caused by expansion of a glutamine (polyQ) repeat in the huntingtin (htt) protein. The selective striatal neurodegeneration induced by this disease causes choreic in ...
An emerging model views gene regulation as a competition for regulatory sequences between transcription factors and nucleosomes at thermodynamic equilibrium. A computational model of the DNA affinity of nucleosomes was recently developed allowing to predic ...
