Natural convection in the cytoplasm: Theoretical predictions of buoyancy-driven flows inside a cell [PDF]
The existence of temperature gradients within eukaryotic cells has been postulated as a source of natural convection in the cytoplasm, i.e. bulk fluid motion as a result of temperature-difference-induced density gradients. Recent computations have predicted that a temperature differential of $\Delta T \approx 1$ K between the cell nucleus and the cell ...

CRISPR-Cas9 screens in human cells and primary neurons identify modifiers of C9ORF72 dipeptide-repeat-protein toxicity. [PDF]
Hexanucleotide-repeat expansions in the C9ORF72 gene are the most common cause of amyotrophic lateral sclerosis and frontotemporal dementia (c9ALS/FTD).

Outer membrane vesicles (OMVs) are important tools in bacterial virulence but their role in the pathogenesis of infections caused by enterohemorrhagic Escherichia coli (EHEC) O157, the leading cause of life-threatening hemolytic uremic syndrome, is ...

A model of calcium-mediated coupling between membrane activity and clock gene expression in neurons of the suprachiasmatic nucleus [PDF]
Rhythms in electrical activity in the membrane of cells in the suprachiasmatic nucleus (SCN) are crucial for the function of the circadian timing system, which is characterized by the expression of the so-called clock genes. Intracellular Ca$^{2+}$ ions seem to connect, at least in part, the electrical activity of SCN neurons with the expression of ...

Retrograde signalling in plants: from simple to complex scenarios
The concept of retrograde signalling posits that signals originating from chloroplasts or mitochondria modulate the expression of nuclear genes. A popular scenario assumes that signalling factors are generated in, and exported from the organelles, then ...

Iron sulfur (Fe-S) clusters and the molybdenum cofactor (Moco) are present at enzyme sites, where the active metal facilitates electron transfer. Such enzyme systems are soluble in the mitochondrial matrix, cytosol and nucleus, or embedded in the inner ...

Complexity of interferon gamma interactions with HSV-1
The intricacies involving herpesvirus persistence are complex. Herpes simplex virus type 1 (HSV-1) uses a variety of receptors to enter cells, and is transported to and from the host cell nucleus over the microtubule railroad via retrograde and ...

Evolution: functional evolution of nuclear structure. [PDF]
The evolution of the nucleus, the defining feature of eukaryotic cells, was long shrouded in speculation and mystery. There is now strong evidence that nuclear pore complexes (NPCs) and nuclear membranes coevolved with the endomembrane system, and that ...
