  2023-12-08

  

  On the other hand, oxygen concentration in tumor tissue also depends on its consumption rate by tumor cells, which decrease will also lead to alleviation of hypoxia. This fact is not taken into account in the majority of studies on the topic, although it is well-known that antiangiogenic therapy doe

  VEGFR2 inhibition using sunitinib does not result in tumor growth reduction or in a further decrease in vessel density in NDRG1 overexpressing glioma rendering these tumors intrinsically resistant to antiangiogenic treatment. Intrinsic resistance to antiangiogenic therapy is defined as a non-respons

  HsALDH enzyme has been purified for the first time in our laboratory from human saliva and has been kinetically characterized using different aromatic substrates [35]. Also, the effect of some common substances frequently encountered by the enzyme in the oral cavity (such as ethanol, hydrogen peroxi

  Despite extensive studies on the expression of T. pallidum-induced pro-inflammatory cytokines, very little is known about T. pallidum-mediated intracellular signaling pathway activation, that leads to cytokine expression in macrophages. A network of signaling molecules, transcription factors, epigen

  Numerous studies have reported high glutamate levels in the brains of patients with depression, indicating that the glutamate system plays a crucial role in depression (Sanacora et al., 2004; Kendell et al., 2005; Hashimoto et al., 2007). Furthermore, several clinically effective antidepressant drug

  2023-12-07

  

  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

  Moreover, our results indicate that ADP is by far a better phosphate donor than AMP (Table 2). Yet, the bindings of AMP and ATP are mutually exclusive, whereas the bindings of ADP and ATP are additive (Fig. 7). The multiplicity of the phosphate donors in the TgAK reaction (Tables 1 & 2), suggests th

  2023-12-07

  

  Adenosine is a ubiquitous homeostatic purine nucleoside that accumulates extracellularly in response to metabolic stresses such as hypoxia and inflammation. Activation of either G protein-coupled adenosine receptors (ARs; A1R, A2AR, A2BR, and A3R) by extracellular adenosine can modulate cell signali

  Renal cell carcinoma (RCC) accounts for more than 12,000 cancer deaths in the United States (Jemal et al., 2003). The current treatment includes surgical resection followed by interleukin-2 or Interferon-α treatment. Some patients experience distant metastatic lesions of RCC. In the last 5 years, re

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