Osteoarthritis increases the expression of leptin and leptin receptors in chondrocytes [ 49], suggesting that physiologic levels of leptin may mediate the production of inflammatory mediators in osteoarthritic but not normal tissue.
In the present study, we investigated this with particular emphasis on whether loss of cytochrome c from mitochondria during heart ischaemia may mediate the increased production of ROS (reactive oxygen species) during subsequent reperfusion that induces mPTP (mitochondrial permeability transition pore) opening.
On the other hand, several studies showed that volatile anesthetic triggered intracellular reactive oxygen species (ROS) production [ 13], and that ROS production may mediate and/or trigger the preconditioning signalling cascade.
As a PHO box has been found overlapping the distal transcriptional starting point of pqsR and as AQ production is no longer enhanced in a phoB mutant, these elements may mediate the increased AQ production observed following phosphate limitation (Jensen et al., 2006).
A chlorogenic acid-induced increase in GLP-1 production may mediate the impact of heavy coffee consumption on diabetes risk.
Synovitis may mediate pain through the production of factors that sensitize or activate sensory nerves.
Increased endothelin production may mediate the tubulointerstitial injury and decrease in GFR associated with metabolic acidosis in CKD [ 10, 23].
Excessive ROS production may mediate toxicity by affecting other processes, such as mitochondrial dynamics and mitophagy, and these may not be effectively targeted by current pharmacological methods.
These results provide evidence that excessive NO production may mediate pulmonary vascular hyperpermeability in MRSA sepsis via up regulation of reactive radicals and VEGF.
Premenstrually, uterine prostaglandin production may mediate an inflammatory response characterized by pain, and during menses abnormally high levels of prostaglandins in menstrual fluid may induce abnormal uterine contractions and pain [ 17, 20].
