Quality control autophagy: a joint effort of ubiquitin, protein deacetylase and actin cytoskeleton.
Autophagy has been predominantly studied as a nonselective self-digestion process that recycles macromolecules and produces energy in response to starvation. However, autophagy independent of nutrient status has long been ...
VCP/p97 is essential for maturation of ubiquitin-containing autophagosomes and this function is impaired by mutations that cause IBMPFD.
VCP (VCP/p97) is a ubiquitously expressed member of the AAA(+)-ATPase family of chaperone-like proteins that regulates numerous cellular processes including chromatin decondensation, homotypic membrane fusion and ...
The genomic analysis of erythrocyte microRNA expression in sickle cell diseases.
(PLoS One, 2008-06-04)
BACKGROUND: Since mature erythrocytes are terminally differentiated cells without nuclei and organelles, it is commonly thought that they do not contain nucleic acids. In this study, we have re-examined this issue by analyzing ...
Serotonin transporter genotype modulates social reward and punishment in rhesus macaques
(PLoS ONE, 2009)
Background: Serotonin signaling influences social behavior in both human and nonhuman primates. In humans, variation upstream of the promoter region of the serotonin transporter gene (5-HTTLPR) has recently been shown to ...
Kinesins at a glance.
(J Cell Sci, 2010-10-15)
Electron tomography of cryofixed, isometrically contracting insect flight muscle reveals novel actin-myosin interactions.
(PLoS One, 2010-09-09)
BACKGROUND: Isometric muscle contraction, where force is generated without muscle shortening, is a molecular traffic jam in which the number of actin-attached motors is maximized and all states of motor action are trapped ...
Role of mast cells in inflammatory bowel disease and inflammation-associated colorectal neoplasia in IL-10-deficient mice.
(PLoS One, 2010-08-17)
BACKGROUND: Inflammatory bowel disease (IBD) is hypothesized to result from stimulation of immune responses against resident intestinal bacteria within a genetically susceptible host. Mast cells may play a critical role ...
Myosin VIIA, important for human auditory function, is necessary for Drosophila auditory organ development.
(PLoS One, 2008-05-07)
BACKGROUND: Myosin VIIA (MyoVIIA) is an unconventional myosin necessary for vertebrate audition -. Human auditory transduction occurs in sensory hair cells with a staircase-like arrangement of apical protrusions called ...
Direct TLR2 signaling is critical for NK cell activation and function in response to vaccinia viral infection.
(PLoS Pathog, 2010-03-12)
Natural killer (NK) cells play an essential role in innate immune control of poxviral infections in vivo. However, the mechanism(s) underlying NK cell activation and function in response to poxviruses remains poorly understood. ...
Localisation and mislocalisation of the interferon-inducible immunity-related GTPase, Irgm1 (LRG-47) in mouse cells
(PLoS ONE, 2010)
Irgm1 (LRG-47) is an interferon-inducible Golgi membrane associated GTPase of the mouse whose disruption causes susceptibility to many different intracellular pathogens. Irgm1 has been variously interpreted as a regulator ...
