  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,

  2024-12-18

  

  A rational approach for the design of new steroid compounds as possible competitive inhibitors of CYP17 include chemical modification at C17 of the enzyme's natural substrates, pregnenolone (1) and progesterone (2), introducing groups with moderate to strong dipole properties at C20, such as oxime a

  2024-12-18

  

  In the pituitary of R. quelen mRNA levels of cyp19a1b were found to be higher in males than females, suggesting a sex-specific function, and perhaps a local action to regulate gonadotropins or other pituitary hormone secretion (Olivereau and Callard, 1985; Zhang et al., 2014). Interestingly, the hig

  2024-12-18

  

  Plasma apelin levels predict the major cardiovascular event after percutaneous coronary intervention in patients with ST elevation myocardial infarction (STEMI), and adverse events are higher in patients with lower plasma apelin levels [75]. Apelin and its receptor are markedly upregulated in the he

  We have recently begun to demonstrate this concept by reporting a novel class of β-hairpin peptidomimetics, built on a piperidine-pyrrolidine semi-rigid β-turn inducer [12] and bearing two recognition pentapeptide sequences, designed on oligomeric and fibril structures of Aβ1-42 (compound 1, Fig. 1)

  Introduction Alzheimer's disease (AD) is a complex neurological disorder characterized by a progressive dementia resulting from synapse failure (Selkoe, 2002, Tanzi, 2005). The amyloid hypothesis maintains that the pivotal event in AD is the production of amyloid-β (Aβ) peptides following the prote

  2024-12-17

  

  The importance of insulin in controlling lipolysis and fat mass is further emphasized by mouse models with alterations in the insulin signaling pathway of adipocytes. For example, mice with a tamoxifen-inducible knockout of the insulin receptor in mature adipocytes reveal a substantial decrease of a

  Our in vitro data show that CyaA does not play a critical role in the bacterial adherence to mammalian cells. This observation is in contrast to previous studies that reported a role for CyaA in FHA-mediated adherence of B. pertussis bacteria to the respiratory epithelial leonurine [37,38]. This di

  A highly attenuated B. pertussis strain, named BPZE1, has recently been described [10]. It produces enzymatically inactive pertussis toxin (PT), no dermonecrotic toxin and only trace amounts of tracheal cytotoxin. Markedly reduced lung pathology was observed in mice intranasally (i.n.) infected with

  Mast cells. Mast galunisertib are immune cells of the myeloid lineage and are ubiquitously present in connective tissues [75]. These cells are involved in the modulation of a number of physiological functions, such as vasodilation, angiogenesis, bacterial, and parasite elimination [75]. Moreover, m

  Conclusion Our study of late-life depression provides evidence of genotype-specific associations between depression and ACE methylation, as well as inverse correlations between ACE methylation and selex secretion. These findings highlight the potential need to consider methylation levels in comb

  2024-12-17

  

  A promising target that is involved in the biosynthesis of the precursor LTA4 is the 5-LO-activating protein (FLAP), which in vivo is seemingly indispensable for LT formation [8], [9]. FLAP, a member of the MAPEG family (membrane-associated proteins in eicosanoid and glutathione metabolism), is an i

  Application of the broad-acting 5-HTR antagonist methiothepin (Bard et al., 1996, Hoyer et al., 1994, Peroutka, 1990) converted the TBS-induced response of both thalamocortical and intracortical A1 synapses from LTP to LTD, an effect that was mimicked by the selective 5-HT2R antagonist ketanserin (L

  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
