  2024-07-09

  

  Studies on both TCDD treated mice and AhR null mice have also pointed to a role of AhR in hematopoiesis [65], [66]. Singh et al. showed that AhR is a negative regulator of HSC (hematopoietic stem cell) proliferation, while deletion of AhR leads to spleen enlargement in juvenile and adult mice [67].

  2024-07-09

  

  AHR-mediated MMP1 upregulation has been shown in response to tobacco smoke [32]. Tobacco smoke contains various AHR ligands such as benzo[a]pyrene. Both benzo[a]pyrene [15] and FICZ [13] are high-affinity ligands for AHR and upregulate CYP1A1 and CYP1B1. FICZ is rapidly degraded by CYP1A1 [20], [33]

  2024-07-09

  

  As we previously observed in the NSFT (Fukumoto et al., 2014), the effect of LY341495 in the FST was also inhibited by a 5-HT1A receptor antagonist, indicating the role of the 5-HT1A receptor in the actions of LY341495. Among the 5-HT1A receptors, which exist both presynaptically and postsynapticall

  The obtained results indicate that even when the impairment of the same forms of memory are present, amnesia can develop in different ways. Impairment of memory reconsolidation in the conditioned food aversion model through both the serotonin receptor antagonist and the antagonist of NMDA glutamate

  Further investigations were concerned to study the mechanisms by which GABA modulates adenosine-mediated effects in hippocampal tissue. From these results it can be concluded that endogenous GABA exerts an inhibitory effect through GABAA receptors via a predominant adenosine-mediated action and this

  Dihydrotestosterone in adult fish and frogs New perspectives and next directions Similar to other androgens, DHT can modulate reproductive endpoints in both fish and amphibians. However, predicting the effects of DHT can be challenging, as reproductive homeostasis is dependent upon the balance

  The anorexic effect observed when AR231630 is infused into the VTA could be the result of the DA release inhibition, as previously described [11]. However, there is also a hedonic aspect in feeding that possibly involves dopaminergic mechanisms of reward. Helm et al. showed a functional link between

  If the lack of specificity and the high pleiotropy may represent a problem in view of the potential chemotherapeutic features of autophagy-inducing agents, it Concanamycin A may switch into an advantage in the case of chemopreventive strategies. In fact, as non-pharmacologic interventions such as li

  Fourth, non-canonical sites may be targeted. Classical benzodiazepines require the presence of a γ subunit for high-affinity binding, which limits their activity to a specific large pool of receptor isoforms, leaving other isoforms unaffected. In particular, δ subunit-containing receptors, as well a

  2024-07-08

  

  A different mechanism has been suggested for the role of TRX1 in ASK1 regulation based on disulfide bond-mediated ASK1 multimerization and its reduction through the thiol-reductase activity of TRX1 (Nadeau et al., 2007, Nadeau et al., 2009). In this model, oxidative stress induces intermolecular dis

  2024-07-08

  

  Since immunoassays cannot specifically quantify each apelin peptide, a more reliable approach, mass spectrometry (MS) has been used recently to quantify and characterize apelin fragments in plasma. Using this technology, Zhen et al. showed that [Pyr-1]-apelin-13 was the major apelin form present in

Many compounds were discovered by natural product screening and developed unchanged, or as semi-synthetic derivatizations. Since the golden age of antibiotic discovery (1940s-mid 1

  It has been proposed that angiotensin II (Ang II) may upregulate COX-2 expression and the subsequent vasoconstrictor prostanoids production through the activation of AT-1 receptors in vascular smooth muscle cells (Hu et al., 2002). Additionally, this peptide is also able to stimulate the generation
