  Kim et al. (2013) found that 6-hydroxydopamine (6-OHDA) promoted the atrophy of dopaminergic neurons associated with the activation of poly (ADP-ribose) polymerase (PARP), the translocation of apoptosis inductor factor (AIF) and the depletion of ATP. An increase in p-AMPK and pS6K (upstream kinase o

  In human epidermoid carcinoma A431 cells, 12-lipoxygenase was significantly increased in glutathione-depleted cells. The relative abundance of phospholipid hydroperoxide versus glutathione peroxidase seems to play an important role in controlling the lipoxygenase reaction [57]. It has been proposed

  2023-10-03

  

  Extracellular adenosine acts as a local modulator of cell function via four adenosine receptor subtypes (A1Rs A2AR, A2BR, and A3R) that are involved in numerous physiological and pathophysiological processes [31]. Each is encoded by a separate gene and has different functions, although with some ove

  2023-10-03

  

  The biology of the A2BR is complex and needs to be considered contextually as the expression and effect of receptor engagement varies according to time post hypoxic injury, cell type and downstream signaling pathway. For example, A2BR expression is dynamic - low under basal and increasing under isch

  Materials and methods Results Discussion Very few ARF inhibitors have been developed to study the key functions these small GTP-binding proteins play in pathophysiology. The natural compound Brefeldin A (BFA) has exhibited drastic effects in cells such as collapse of the Golgi because of it

  In the olfactory bulb, expression was especially prominent in the mitral cell layer from embryonic stages to adult tissues (Figs. 1D–G). By E14–E16, Ack1 signal was remarkably intense in the proliferative ventricular zone (Fig. 1D). From E18 to adult, expression was also observed in glomerular and g

  During the course of angiogenesis, the overactivated angiogenic stimulators are responsible for carrying out abnormal proliferation in the retinal microvasculature, resulting in the formation of various immature blood vessels. These newly formed blood vessels become the prime spots for leakage of th

  It has been proposed that angiotensin II (Ang II) may upregulate COX-2 expression and the subsequent vasoconstrictor prostanoids production through the activation of AT-1 receptors in vascular smooth muscle cells (Hu et al., 2002). Additionally, this peptide is also able to stimulate the generation

  2023-10-01

  

  Although AMPK is a negative regulator of bioenergetic reprogramming in cancer cells, little is known about the role of AMPK in immunometabolism in sepsis. Our current study indicates that AMPKα dysfunction enhances PKM2-dependent aerobic glycolysis, which results in HMGB1 release in macrophages and

  Our results showed that oral administration of cordycepin, in the concentrations of 5 and 10mg/kg for 3weeks, exerted no influence on body weight and hippocampus weight in mice. Although some reports have pointed out that cordycepin had toxic effects because it may be potential for inducing cell dea

  Although effects of low concentrations of agonist were not as thoroughly documented for heteromeric receptors such as the major Lithocholic Acid α4β2 nAChR, a similar mechanism of action was described to explain the potentiation of these receptors with low concentrations of acetylcholine-esterase-in

  The present in vitro pharmacological experiments revealed that the cholinergic up-regulation of VEGF expression in neurons and astrocytes was mainly mediated by nicotinic AChR and muscarinic AChR, respectively. In addition, neuronal VEGF expression was elevated by endogenous ACh in a manner that was

  Another important question concerns the mechanism by which a polyubiquitinated substrate is released from the Cdc48 complex and passed on to downstream components, such as the proteasome. There are at least three proposed models. In the first, a ubiquitinated substrate is transferred by ubiquitin-bi
