  2024-08-06

  

  The AHR potentially enhances IDO-expression, possibly via crosstalk with several inflammatory signaling pathways (shown by now for IL6 and ‘signal transducer and activator of transcription’ (STAT) 3, and for NFκB, toll like receptor-pathways) [56,59,60]. IDO metabolizes Trp to kynurenines, which are

  Impact of global AHR deficiency on diet-induced obesity Two subsequent studies in which AHR function was affected at the whole animal level corroborated the role of AHR in dietary obesity. Xu et al. [14] showed that on a high-fat diet, both AHR-deficient Ahr−/− and hemizygous Ahr+/− mice gained s

  2024-08-06

  

  In summary, the different types of interstitial cells found in the current study are illustrated in Fig. 7A (see legend for further details), which is suggestive of a heterogeneous complex network of interstitial cells communicating with each other. The possible signaling pathways involving this int

  2024-08-06

  

  The direction of glutamate transport by the cell membrane transporter is reversible. As mentioned above, glutamate transport is an electrogenic process associated with a transmembrane ion gradient established by the Na+-K+ pump through hydrolysis of adenosine triphosphate. Under conditions of energy

  2024-08-06

  

  The extent to which GPCR oligomerization is a regulated process still remains unclear. Reported effects of ligands on both GPCR homo- and heteromers are highly variable and depend on GPCR subtypes and the specific ligand used. According to our data, chronic treatment of mice with both paroxetine or

  2024-08-06

  

  The relatively high concentration of 5-HT used in this study (100 µM) is consistent with the concentrations used in other published ex vivo studies (Ropert and Guy, 1991, Passani et al., 1994, Shen and Andrade, 1998). In our paradigm 5-HT was focally applied at the surface of the slice via a fast pe

  2024-08-06

  

  Our results using RT-PCR confirm earlier findings (Wilisch et al., 1999, Bruno et al., 2004) including the presence of both the P3A+ and P3A− isoforms of the α-subunit (Beeson et al., 1990). The lack of detection of the ε-subunit mRNAs in some thymomas, and lack of α-, β-, δ- and γ-subunit mRNAs by

  2024-08-06

  

  Overexpression of SMAD3 and SMAD4 strongly enhanced luciferase activity of the new pN10 reporter gene construct which was further reinforced by addition of TGFβ. Serial mutations of SBE-1 and SBE-2 led to a slight loss in 5-LO promoter inducibility. The data demonstrate that the two SBEs within the

  2024-08-06

  

  Direct inhibition of 5-LO activity by BRP-187 is clearly evident in cell-free assays using PMNL homogenates and isolated human recombinant 5-LO as enzyme source. In such assays, pure FLAP inhibitors like MK886 are inactive [9], [10], [29], [44]. Wash-out experiments and studies using the nonionic de

  Acknowledgments P450c17 is expressed in several steroidogenic tissues, including the adrenal cortex, the ovary, and the testes (). Thus, 17α-hydroxylase/17,20-lyase is a key enzyme required for the production of both cortisol and sex steroids. This enzyme defect blocks the synthesis of cortisol,

  Several 16-dehidropregnenolone derivatives functionalized at C3, C4, C5 and C6 (Fig. 7) were prepared and evaluated as 5α-reductase inhibitors bearing in mind that after the formation of an enzyme-steroid complex a nucleophilic portion of the enzyme attacks the double bond of the steroid through Mic

  Steroidal CYP17 inhibitors can further be classified based on their mode of action, namely as mechanism-based inhibitors and type I and type II competitive inhibitors [129]. Recent studies investigated other biological targets than CYP17, and some new compounds have shown interesting dual activity a

  ATX/LPA signaling in cancer is also well known to promote chemotherapy and radiotherapy resistance [7]. Furthermore, others have recently shown that endothelial-derived ATX activity in renal cell carcinoma promotes renal tumorgenesis and acquired resistance to sunitinib through an IL-8-mediated mech

  While increased arginase levels has been shown in animal models and in humans with cardiovascular dysfunction [16], [22], [23], it is unknown whether plasma levels or activity of Arginase may predict ED risk. In addition, recent evidence suggests that plasma l-arginine hydrolysis by arginases limits
