Different stimuli

mRNA stabilization plays an important role in the changes in protein expression initiated by inducers of inflammation or direct cell stress such as UV light. This study provides evidence that stabilization in response to UV light differs from that induced by proinflammatory stimuli such as bacterial lipopolysaccharide or interleukin (IL)-1. Firstly, UV-induced stabilization is independent of the p38 MAP kinase pathway, which has previously been shown to medi-ate stabilization induced by IL-1 or lipopolysaccharide....

All higher organisms divide major biochemical steps into different cellular compartments and often use tissue-specific division of metabolism for the same purpose.Such spatial resolution is accompanied with temporal changes of meta-bolite synthesis in response to environmental stimuli or developmental needs.Although analyses of primary and secondary gene products, i.e. transcripts, proteins, and metabolites, regularly do not cope with this spatial and temporal resolution, these gene products are often observed to be highly coregulated forming complex networks....

While cardiac hypertrophy elicited by pathological stimuli eventually leads to cardiac dysfunction, exercise-induced hypertrophy does not. This sug-gests that a beneficial hypertrophic phenotype exists. In search of an under-lying molecular substrate we used microarray technology to identify cardiac gene expression in response to exercise. Rats exercised for seven weeks on a treadmill were characterized by invasive blood pressure mea-surements and echocardiography.

Endovanilloids are defined as endogenous ligands of the transient receptor potential vanilloid type 1 (TRPV1) protein,a nonselective cation channel that belongs to the large family of TRP ion channels,and is activated by the pungent ingredient of hot chilli peppers,capsaicin. TRPV1 is expressed in some nociceptor efferent neurons, where it acts as a molecular sensor of noxious heat and low pH. However,the presence of these channels in var-ious regions of the central nervous system,where they are not likely to be targeted by these noxious stimuli,suggests the existence of endovanilloids.

Nuclear factor-kappaB (NF-jB) has been proposed to serve a dual func-tion as a regulator of neuron survival in pathological conditions associated with neurodegeneration. NF-jB is a transcription family of factors com-prising five different proteins, namely p50, RelA⁄p65, c-Rel, RelB and p52, which can combine differently to form active dimers in response to external stimuli.

Diffuse noxious inhibitory controls (DNIC) can be produced by different types of conditioning stimuli, but the analgesic properties and underlying mechanisms remain unclear. The aim of this study was to differentiate the induction of DNIC analgesia between noxious electrical and inflammatory conditioning stimuli. Methods: First, rats subjected to either a supramaximal electrical stimulation or an injection of high-dose formalin in the hind limb were identified to have pain responses with behavioral evidence and spinal Fos-immunoreactive profiles. Second, suppression of tail-flick...

Coma: a state of unconsciousness from which the patient cannot be aroused, even by powerful stimuli. Traumatic brain injuries are the most frequent cause; other causes include severe uncontrolled diabetes mellitus, liver disease, kidney disease, and neurologic conditions Dementia: a general loss of mental abilities, including impairment of memory and often impairments in speech, coordination, ability to understand sensory stimuli, and other mental faculties.

Tumor angiogenesis is a complex process involving many different cell types that must proliferate, migrate, invade, and differentiate in response to signals from the tumor microenvironment. Endothelial cells (ECs) sprout from host vessels in response to VEGF, bFGF, Ang2, and other proangiogenic stimuli. Sprouting is stimulated by VEGF/VEGFR2, Ang2/Tie-2, and integrin/extracellular matrix (ECM) interactions.
