  2023-01-14

  

  Phosphodiesterase inhibition increases the intracellular levels of cAMP to restore spontaneous contraction (Essayan, 2001, Qi and Kwan, 1996), acting downstream of adenylyl cyclase. Therefore, cardiac arrest induced by decreased intracellular cAMP levels could be reversed by phosphodiesterase inhibi

  2023-01-13

  

  The knowledge on the structure of CYP17, including its active site, provides a rationale for understanding many mutations that are found in enzyme dysfunction in clinical disease as well as the enzyme's dual hydroxylase and lyase catalytic capabilities. This knowledge will assist rational drug desig

  The 5α-reductase activity in patients with 21-OHD, as assessed by the 5α-THF to 5β-THF (ratio 3) and by the 5α-17HP to 17HP (ratio 4) ratios, showed a similar pattern of activities (Fig. 2A–C) and significant correlations (ratio 1 vs. ratio 3; rs=0.67; pIn SB-715992 to the 5α-reducase activity, the

  2023-01-13

  

  Since obesity appears to impact leptin and adiponectin levels in opposite manners, several studies have suggested that the serum adiponectin/leptin ratio may be a key parameter in indicating the relative risk of postmenopausal breast cancer (Ollberding et al, 2013, Cleary et al, 2009). Therapeutic s

  2023-01-13

  

  The enzyme Arginase 1 (ARG1) plays a role in the hepatic urea cycle by hydrolyzing L-arginine to L-ornithine and urea [13]. In the context of macrophages and MDSCs, ARG1 expression redirects L-arginine metabolism to abolish cytotoxic nitric oxide production [14], suppress T-cell function [15], [16],

  The role of apelin in respiratory diseases At present, several scientific studies have suggested that the apelin/APJ system may play an important role in the development of pulmonary diseases (Table 4). For example, in an experiment on rats suffering from acute lung injury, apelin-13 decreases th

• These mutations induce the gene auto activation

  2023-01-10

  

  These mutations induce the gene auto-activation in 10–40% of adenocarcinomas, triggering the EGFR-signaling pathway in the absence of ligand. That leads to an uncontrolled acceleration of cell proliferation, survival and anti-apoptotic signals (Couraud et al., 2012). The frequency of these mutations

  The inflammatory cytokine IL-6 is an additional factor that has been hypothesized to contribute to epinephrine-mediated repression of drug detoxifying proteins such as CYP3A4 (Aninat et al., 2008). Indeed, this CYP is well-known to be repressed by IL-6 (Dickmann et al., 2011) and epinephrine has pre

  In previous research, we determined that blocking mAC during heparin-induced capacitation result in sperm having a lesser oxygen consumption, suggesting that cAMP produced by this enzyme would be linked to mitochondrial activity and, therefore, with the regulation of sperm metabolism (Fernández and

  2023-01-10

  

  ADORs accomplish a variety of physiological effects in different tissues. In neurons, ADORs regulate the release of neurotransmitters such as dopamine and glutamate (Ferré et al., 1992; Fredholm and Dunwiddie, 1988; Ginsborg and Hirst, 1972; Gonçalves et al., 2015; Quarta et al., 2004; Stella et al.
