  2023-01-05

  

  As cytosolic acetyl-CoA levels in hepatocytes descend, cellular production and concentration of cholesterol go down, a change that is known to be sensed by the Sterol response element binding protein (SREBP)/Cleavage-Activating Protein system, leading to SREBP escort to the Golgi apparatus, cleavage

  l-Arginine supplementation was reported to be efficient, inefficient or toxic in aged patients. The present study does not support our hypothesis that increased tissue arginase activity may account for the ineffectiveness and even the toxicity of l-arginine supplementation in ageing. Indeed, except

  Maduramicin is a polyether ionophore antibiotic that has the smallest margin of safety between the maximum authorized dosage and the minimum toxic concentration. Clinical signs of maduramicin intoxication are similar to that of other ionophores, often causing feed refusal, anorexia, respiratory dist

  Future directions-outlook Peptide-based macrocycles are among the privileged scaffolds in antibiotic drug discovery. 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

  Acknowledgments Introduction Angiotensin II (AngII) is among the most potent vasoactive substances produced in humans. Its effects are numerous, from vasoconstriction to control of fluid and electrolytes balances. Many of the physiological and pathological effects of AngII are mediated by the

  Immunohistochemistry: Hearts from young and aged mice were collected at the indicated times, fixed overnight in 10% formalin, and embedded in paraffin. Serial 5-μm heart sections from each group were analyzed. Samples were stained with H&E for routine histologic examination. Immunohistochemical stai

  There is a growing body of evidence showing that pentobarbital causes memory disorders [3], [4], [5]. Our results that a single injection of pentobarbital into bilateral hippocampus significantly impaired hippocampus-dependent spatial memory retrieval (Fig. 1) add support to that evidence. Previous

  Histochemical analyses using antibody or cDNA probes reveal the precise cellular location of the 12S-lipoxygenases in tissues of interest. An immunohistochemical study in various rat tissues showed specific expression of the leukocyte-type 12S-lipoxygenase in macrophages in lung and spleen [27]. In

  Exposure to B[a]P is an epidemiologically proven cause of lung cancer (Hecht, 2003; Rojas et al., 2004; Alexandrov et al., 2010), and the formation of B[a]PDE-N2-dG adducts is considered to be the critical event in lung tumorigenesis by B[a]P. On the other hand, there is evidence suggesting that the

  An alternative approach to the administration of ADO agonists is to amplify the actions of endogenous ADO by inhibiting the ADO-metabolizing enzyme, ADO kinase (AK). Inhibition of AK has the net effect of potentiating the local concentration and the effects of ADO in the extracellular compartment. T

  AXL is a member of the TAM (Tyro3, Axl, Mer) family of receptor tyrosine kinases (RTKs) [4]. Elevated AXL expression could promote oncogenic processes such as cell growth, migration, invasion, and epithelial-to-mesenchymal transition (EMT), which substantially contribute to tumor progression and poo

  With regard to the first question, subcellular fractionation studies revealed that BDK and PPM1K are clearly detectable in both the mitochondrial and cytosolic subcellular fractions, thus making it possible for these enzymes to interact with both the BCKDH and ACL substrates. The preferential presen

  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

  AP-1 was originally described as a heterodimer of the bZIP proteins c-Jun and c-Fos. The experiments described here showed that stimulation of TRPV1 channels induced the expression of both of these classical constituents of AP-1. The essential role of both proteins was analyzed in a series of experi
