Stressful events during the juvenile period may have pronounced proactive effects on anxiety-related behaviors, but linking these to specific GABA(A) subunits is made difficult by the diversity
of GABA changes that are evident as well as the dimorphic nature of these variations. Nevertheless, these GABA(A) sex-specific subunit variations may be tied to the differences in anxiety in males and females. (C) 2012 IBRO. Published by Elsevier Ltd. All rights reserved.”
“Motility structures, called flagella, have been described in all three domains of life: Bacteria, Archaea and Eukarya. These structures are well studied in both Bacteria and Eukarya. However, already in eukaryotes there exists some confusion as to whether these structures should actually be BAY 63-2521 cost called cilia. With increased studies conducted on organisms of the third domain of life, the Archaea, it has become clear that the archaeal flagellum
only functionally appears similar to the GW4064 cell line bacterial flagellum, whereas it structurally resembles a bacterial type IV pilus. To resolve confusion due to unclear nomenclature, we propose renaming the archaeal flagellum as the ‘archaellum’. This will make clear that the archaellum and the bacterial flagellum are two distinct structures that happen to both be used to enable microorganisms to swim.”
“Green tea polyphenols exhibit mafosfamide multiple antitumor activities, and the mechanisms of action are not completely understood.
Previously, we reported that green tea extract (GTE)-induced actin remolding is associated with increased cell adhesion and decreased motility in A549 lung cancer cells. To identify the cellular targets responsible for green tea-induced actin remodeling, we performed 2-DE LC-MS/MS of A549 cells before and after GTE exposure. We have identified 14 protein spots that changed in expression (>= 2-fold) after GTE treatment. These proteins are involved in calcium-binding, cytoskeleton and motility, metabolism, detoxification, or gene regulation. In particular we found upregulation of several genes that modulate actin remodeling and cell migration, including lamin A/C. Our data indicated that GTE-induced lamin A/C upregulation appears to be at the transcriptional level and the increased expression results in the decrease in cell motility, as confirmed by siRNA. The result of the study demonstrates that GTE alters the levels of many proteins involved in growth, motility and apoptosis of A549 cells and their identification may explain the multiple antitumor activities of GTE.”
“Although previous investigations agree in showing significant cortical modifications related to short-term limb immobilization, little is known about the functional changes induced by non-use. To address this issue, we studied the kinematic effect of 10 h of hand immobilization.
