FEBS Letters, EarlyView.The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Neural stem cells in development and cancer
, 2008 Neural stem cells are defined by their unique ability to undergo self-renewal divisions. By dividing asymmetrically, a stem cell simultaneously produces a daughter cell that retains stem cell identity, whereas the other starts to differentiate and ...

Analysis of the DNA damage response in living cells [PDF]
, 2007 DNA lesions arising from environmental and endogenous sources induce various cellular responses including cell cycle arrest, DNA repair and apoptosis. Although detailed insights into the biochemical mechanisms and composition of DNA repair pathways have ...

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes
FEBS Letters, EarlyView.Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Role and specificity of regulatory T cells during retroviral infection [PDF]
, 2009 During chronic viral infection of the hematopoietic system, both virus-mediated and immune-mediated effects may cause bone marrow dysfunction leading to cytopenias. To study the pathological consequences of the T helper response to unresolving chronic

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.
