microRNAs (miRNAs) are small noncoding RNAs that have been linked to a number of disease-related signal transduction pathways. Several studies indicate that they are also involved in nociception. It is not clear, however, which miRNAs are important and which genes are modulated by miRNA-associated mechanisms. This study focuses on the regulation and(More)
Reactive oxygen species (ROS) contribute to sensitization of pain pathways during neuropathic pain, but little is known about the primary sources of ROS production and how ROS mediate pain sensitization. Here, we show that the NADPH oxidase isoform Nox4, a major ROS source in somatic cells, is expressed in a subset of nonpeptidergic nociceptors and(More)
UNLABELLED The activation of the adenosine monophosphate (AMP)-activated kinase (AMPK) has been associated with beneficial effects such as improvement of hyperglycemic states in diabetes as well as reduction of obesity and inflammatory processes. Recent studies provide evidence for a further role of AMPK in models of acute and neuropathic pain. In this(More)
miRNAs are small noncoding RNAs that are important players in development, as well as in a number of physiological and pathophysiological processes. Due to their regulatory role in protein expression, it has been assumed that they are associated with peripheral and central sensitization mechanisms in the nervous system after nociceptive insults. However,(More)
MicroRNAs (miRNAs, miRs) and small interfering RNAs (siRNAs) form a class of small noncoding RNAs of 19–25 nucleotides that mediate RNA interference (RNAi) by post-transcriptionally modulating gene expression. While siRNAs have already been addressed in many papers, including pain-related RNAi studies (reviewed in [32]), naturally occurring miRNAs are a(More)
Inhibitor-κB kinase ε (IKKε) was only recently identified as an enzyme with high homology to the classical I-κB kinase subunits, IKKα and IKKβ. Despite this similarity, it is mainly discussed as a repressor of viral infections by modulating type I IFNs. However, in vitro studies also showed that IKKε plays a role in the regulation of NF-κB activity, but the(More)
Atomoxetine (ATX), a selective norepinephrine reuptake inhibitor, is a non-stimulant approved for the treatment of attention deficit/hyperactivity disorder (ADHD). Little is known about the molecular basis for its therapeutic effect. The objective of this animal study was to determine alterations in gene expression patterns in the prefrontal cortex after(More)
p21-activated kinases (PAKs) are involved in signal cascades relevant for nociceptive processing and neuropathic pain. Particularly, the recently described group B PAKs 4, 5 and 6 regulate MAP-kinases and the rearrangement of the actin cytoskeleton, both of which have been linked to pain processing. However, a specific role of these PAKs in nociception has(More)
Inhibitor-kB kinase « (IKK«) was only recently identified as an enzyme with high homology to the classical I-kB kinase subunits, IKKa and IKKb. Despite this similarity, it is mainly discussed as a repressor of viral infections by modulating type I IFNs. However, in vitro studies also showed that IKK« plays a role in the regulation of NF-kB activity, but the(More)
TANK-binding kinase (TBK1) is a non-canonical IκB kinase (IKK) involved in the regulation of type I interferons and of NF-κB signal transduction. It is activated by viral infections and inflammatory mediators and has therefore been associated with viral diseases, obesity, and rheumatoid arthritis. Its role in pain has not been investigated so far. Due to(More)
