  cAMP is a key secondary messenger which transduces extracellular signals at glucagon receptors to intracellular effector molecules. cAMP-protein kinase A (PKA) pathway increases the gene expression of enzymes including phosphoenolpyruvate carboxykinase (PEPCK) and glucose 6-phosphatase (G6Pase) whic

  Materials and methods Results Discussion Several studies highlighted an improvement of glycaemic control in diabetic patients receiving sunitinib, while the underlying mechanism remained still elusive [3], [4], [5], [6], [8]. The present study gives evidence that sunitinib directly and spec

  2021-09-24

  

  Endothelial cells receive a variety of information from the environment which finally guides them through all phases of neovascularization. Angiogenic signals enhance the proliferation of endothelial cells, upregulated resistance to apoptosis, alterations within proteolytic balance, reorganization o

  2021-09-24

  

  At the heart of ferroptosis is a process of lethal lipid peroxidation, which is the oxidative addition of molecular oxygen (O2) to lipids, such as polyunsaturated fatty acyl tails in phospholipids. The first descriptions of such enzymatic reactions were in 1955 by Peterson and colleagues [50] and Ro

  2021-09-24

  

  Here, we dissect X chromosome dosage compensation (DC) in C. elegans to determine the effect of chromatin modifications on higher-order chromosome structure during long-range gene regulation. DC is exemplary because it controls hundreds of genes simultaneously, it distinguishes X chromosomes from au

  There has been some debate about which types of liver cells might be able to activate canonical Hh signalling during liver injury. These uncertainties reflect technical challenges imposed by imperfect and inconsistent reagent specificity and the nature of the signalling process itself, which is quit

  ICLs represent ICL Inducers in Cancer Therapy Nitrogen mustards with aromatic substituents (chlorambucil, melphalan) or a bioactivatable phosphoramide group (cyclophosphamide) were one of the first identified DNA crosslinkers. These agents are still used in combined schemes for the therapy of chr

  2021-09-23

  

  HBV is an enveloped, double-stranded DNA virus, which is transcripted into four major transcripts [6]. Among them, the 3.5 kb pregenomic RNA (pgRNA) directs the translation of HBV polymerase, core protein and acts as template for reverse transcription. So viral transcription is a key step of virus l

  Experimental section Results and discussion Conclusion The evaluation of the inhibitory potential of these derivatives towards eight kinases showed that the brominated hybrids (3k) and (3l) are the most active against the PIM1 and CLK1 kinases. The methylation of the nitrogen exactly of th

  Over the last 15 years, numerous studies gave insights into sGC activation and binding of activators: Photoaffinity labelling studies with cinaciguat suggested the N-terminus of the β1 subunit as target region for this new drug [17]. Schmidt et al. identified the amino acids tyrosine 135, serine 137

  It has been shown that GPR55 receptors coupled to G12/13 proteins down-regulate reactive oxygen species (ROS) production and degranulation in human neutrophils [9]. MCs degranulation stimulated by IgE/Ag also requires the generation of ROS [64]; therefore, the possibility to explore the inhibitory a

  Introduction In the treatment of patients with AIDS and human immunodeficiency virus type 1 (HIV-1), anti-retroviral therapy (ART), which uses anti-HIV drugs such as protease inhibitors, integrase inhibitors and reverse transferase inhibitors, has made a major contribution. There are still some s

  Adenosine triphosphatase (ATP) is a signaling molecule in acute pain and chronic pain(Burnstock, 2009, Burnstock, 2013, Burnstock, 2014, Chizh and Illes, 2001). It is also known that presynaptic A1 receptors are involved in the inhibition of transmitter release (Vizi and Knoll, 1976). Extracellular

  In the present study, recipient oestradiol serum levels on the day of donor oocyte retrieval or warming were found to be significantly higher in the antagonist group and higher than 100 pg/ml in all cases. Serum oestradiol level has been reported to have no effect on endometrial receptiveness in ooc

  Generally speaking, the regulation of GnIH on gonadotropins synthesis and release, although controversial, could be direct and/or indirect via GnRH, among others peptides. In this sense, different scenarios have been reported in vertebrates. In mammalian and avian species, GnIH fibers reach the medi
