  2023-08-02

  

  Asparagine synthetase (ASNS) is a glutamine amidotransferase that catalyzes ATP-dependent synthesis of asparagine and glutamate from aspartate and glutamine. Upregulation of ASNS expression renders leukemia cells resistant to l-asparaginase treatment, and ASNS is essential for cell survival in the a

  2023-08-02

  

  Due to metabolic variations, it is important to consider arginine metabolism and dependency in specific contexts to identify precise patterns. This is best illustrated for ASS: while ASS deficiency correlates with worse prognosis in sarcomas, ASS levels positively correlate with a poor prognosis in

  We next developed a system for staging severity. Our guiding principles were the following. Two types of information about the research participant are staged independently from each other: (1) grading disease severity using biomarkers and (2) grading the severity of cognitive impairment.

  In glaucoma, the primary retinal defect appears in the GCL, whereas the other retinal layers appear normal (Kendell et al., 1995). In the current work, chronic elevation of IOP induced RGC apoptosis, especially in the GCL, and α2 adrenergic treatment reduced RGC apoptosis. Various studies have repor

  Discussion With recently improved understanding of the role of βARK1 in the progression of HF and as a potential therapeutic target in HF, we explored the relationship between plasma βARK1, as a marker of chronic sympathetic overactivation, and physical symptoms in HF. Our main findings were 1) e

  2023-08-02

  

  Since forskolin is known to act directly at the catalytic site of adenylate cyclases near the ATP binding (Tesmer et al., 1997), the synergistic and/or permissive effect of gonadotropins on FSK activity must occur at the level of AC itself or very near, at the level of one of its direct partner. The

  2023-08-02

  

  Adenosine is a ubiquitous homeostatic substance released from most cells, including neurons and glias. Endogenous adenosine acts at four principal G-protein-associated receptor subtypes: A1, A2a, A2b and A3 (Ralevic and Burnstock, 1998). The stimulation of adenosine receptors by extracellular adenos

  2023-08-02

  

  Diabetes or inflammation is associated with up-regulation of A2AAR (Pang et al., 2010). High levels of A2AARs are found in macrophages and microglial cells that are poised, on activation, to abrogate the immune response (Trincavelli et al., 2008). In addition, hyperglycemia is associated with increa

  2023-08-02

  

  AdK as an important upstream regulator of adenosine-based homeostasis represents a promising drug target since it leads to an increase in adenosine concentrations. Taking into account that the adenosine formation is only increased in affected tissues under stress with high adenosine levels, AdK inhi

  2023-08-01

  

  Although the mechanisms of APP secretion are well characterised (for review see Ref. [1]), production of soluble AChE species is less well understood although we have reported that a metalloproteinase can shed AChE similarly to APP [16], [17]. Recently it has also been demonstrated that cellular pre

  It has been recognized for decades that neurons in the mammalian central nervous system may release both a fast-acting, typically amino acid derived neurotransmitter such as glutamate or GABA, and a second peptidergic neuromodulatory molecule such as neuropeptide Y, substance P, or cholecystokinin.

  Conflict of interest Acknowledgments Introduction Inflammation is a protective response of the microcirculation to harmful stimuli. Yet, excessive inflammation is potentially harmful and a characteristic of many chronic diseases [1]. 5-Lipoxygenase (5-LO, EC1.13.11.34) contributes to the in

  In summary, the role of 5-HT and different types of 5-HTRs in gating plasticity induction in neocortical circuits remains unclear, with variable and seemingly contradictory effects reported for LTP induction in cortical sensory fields (e.g., V1, enhanced LTP: Inaba et al., 2009, Kojic et al., 1997,
