  Researchers demonstrated that mitochondria are the main producers of ROS and are the most sensitive to the effects of ROS. Mitochondria-mediated apoptosis may not be limited to the role of cytochrome c in the activation of caspase-3 and ROS may provide an alternate mitochondrial signaling pathway (H

  2023-04-12

  

  Additional support for a role of HMGN1 in enhancing DNA repair comes from studies of transcription-coupled repair (TCR) in human cells. Lesions in the template strand of DNA induced by UV light stall the movement of RNA polymerase II (RNAPII) and interrupt transcription. Removal of these transcripti

  Functional repercussions of each trimming pathway A main difference between the two pathways presented in Fig. 1 lies in enzyme kinetics and selectivity. In pathway #1, the substrate for ERAP1 is free peptide, and so both kinetics and selectivity are determined by interactions between the peptide

  False positivity of Anti-AChR Ab titers, due to cross reactivity with bungarotoxin, has previously been demonstrated. One such study reported that patients with amyotrophic lateral sclerosis, who had received long term snake venom therapy, had developed antibodies to bungarotoxin and hence demonstra

  Introduction The apelin receptor (angiotensin receptor-like 1, APJ) is a seven transmembrane receptor (7TMR) that belongs to the class A peptidergic G protein-coupled receptors (GPCR) superfamily [1]. The endogenous ligands of APJ are the different isoforms of apelin (namely apelin-13, −17, and −

  Intracellular Signaling Cascades. From ligand sensitization to translation of genes, all cellular processes are dependent on the intracellular levels and activity of partners involved in the signaling pathway. These signaling events lead to critical post-translational modifications including phospho

  From a clinical utility standpoint, this study showed that AR can be useful in the GATA3-positive tumor of unknown origin setting. Epidemiologically, in this setting, the top 2 diagnoses in the differential diagnosis are metastatic carcinoma of breast origin or urothelial origin [18]. Seven out of 1

  What is the mechanism by which Wnt7a-Fz7 signaling enhances AMPAR localization and synaptic strength? Following induction of LTP, the number of AMPARs rapidly increases at extrasynaptic sites (Makino and Malinow, 2009, Yang et al., 2008a) through PKA-dependent phosphorylation of GluA1 at S845 (He et

  2023-04-10

  

  Epidermal growth factor (EGF) has been shown to increase the 12S-lipoxygenase mRNA level by about two-fold in human epidermoid carcinoma A431 cells [71]. This enzyme was shown to be of the platelet-type and associated with the microsomal fraction of the cells [71], [72]. A requirement for EGF recept

  The relationship between AG and tau deposition in the presence of Aβ burden warrants more research in AD and in other primary tauopathies (not associated with accumulation of Aβ plaques). Our findings highlight the importance of measuring AG, as this relationship was not evident for total proteasome

  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
