  Acknowledgements Introduction Double-stranded DNA breaks (DSBs) are among the most deleterious DNA lesions that threaten genomic integrity. DSBs are generated not only by exogenous DNA-damaging agents but also by normal cellular processes such as V(D)J recombination, meiosis, and DNA replicati

  ASK1 belongs to the family of MAPKKK. ASK1-mediated apoptosis is involved in the pathogenesis of several diseases such as I/R injury, infectious diseases and neurodegenerative disorders [33], [34], [35]. ASK1 can be activated through different mechanisms. One mechanism is that oxidative stress direc

  Previous studies have thus demonstrated that AR activation generally correlates with the promotion of urothelial carcinogenesis and cancer growth. In this article, we review available data suggesting their modulation through the AR pathway as well as correlations of AR signals with sensitivity to co

  2024-10-30

  

  Aerobic exercise plays an important role in the regulation of AZD1152-HQPA metabolism in the skeletal muscle. It is also associated with increases in AMPK and GLUT4 levels, resulting in the improvement of the glucose uptake signaling pathway [17,18]. Recently, it has been shown that exercise marked

  As noted above, yeasts, particularly S. cerevisiae (Frey and Röhm 1978; Trumbly and Bradley 1983), produce APs, but these are intracellular enzymes located in the vacuolar compartment, with the exception of aminopeptidase II. About 40% of aminopeptidase II activity is detected as external enzyme, li

  When arachidonic 69 7 is used as a substrate, the platelet-type 12S-lipoxygenase produces predominantly the 12S-hydroperoxy derivative. In contrast, the leukocyte-type 12S-lipoxygenases generate substantial amounts of the 15-lipoxygenase product in addition to the 12S-hydroperoxy derivative. The ra

  2024-10-30

  

  Pituitary adenylate cyclase-activating polypeptide (PACAP) is a member of the secretin/growth hormone-releasing hormone (GHRH)/vasoactive intestinal peptide (VIP) family, with potent anti-inflammatory and potent cytoprotective properties [[6], [7], [8], [9], [10], [11], [12], [13]]. PACAP exists as

  2024-10-30

  

  The activation of the A2BR subtype triggers different intracellular metabolic pathways, often linked to the activation of adenylyl cyclase and increased levels of intracellular cAMP (Lynge et al., 2003, Bernareggi et al., 2015). The nAChR-channel L-685,458 mediated by the cAMP/PKA pathway was repor

  Adenosine and tumor microenvironment In the majority of carcinogenic processes a proinflammatory state is generated [36], [37]. In addition, a tumor hypoxic environment is generally due to inadequate perfusion of oxygen to the tumor [38]. Immunomodulators are molecules that regulate the immune r

  2024-10-30

  

  An alternative approach to the administration of ADO agonists is to amplify the actions of endogenous ADO by inhibiting the ADO-metabolizing enzyme, ADO kinase (AK). Inhibition of AK has the net effect of potentiating the local concentration and the effects of ADO in the extracellular compartment. T

  Tension within the network could be explained by two potential mechanisms: the more classical contractility that is dependent on motor proteins that are pulling Streptozocin filaments towards each other [10]; or contractility that is caused by disassembly of a crosslinked network of actin filaments

  The difficulty of characterizing nAChRs in the central nervous system is also exemplified by early observations that nicotine caused no detectable effect when applied on a brain slice and it is only with the focal and high time resolution of more recent experiments that the effects of nicotinic neur

  A combination of factors might, however, account for the low rate of success of drug development for neuropsychiatric disorders. First, in most neuropsychiatric disorders, the symptomatology is heterogeneous and the neurobiology remains poorly understood, making therapeutic targets difficult to iden

  Additional evidence for a putative role of COXs and 5-LOX in AD derives from pharmacological studies using inhibitors of these enzymes (for review, see Firuzi and Praticò, 2006). In addition to helping delineate the pathobiological mechanisms of AD, these results raise hope for discovering novel the
