  2024-08-05

  

  Phagosomes acquire some hydrolases early during their journey from the cell surface to lysosomes. An example for such hydrolase is cathepsin H which is most concentrated in the early phagosome at a pH of approximately 6.3 (Claus et al., 1998), the pH optimum of enzyme activity (Schwartz and Barrett,

  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

  2024-08-05

  

  Introduction Lipoxygenases (LOXs) are key enzymes that catalyze the polyunsaturated fatty acids (PUFAs) such as arachidic ISX 9 (AA), linoleic acid (LA) and others unsaturated fatty acids (Brash, 1999). LOXs are expressed in immune, neural, epithelial, tumor cells and other cells (Claesson, 2009).

  2024-08-05

  

  In receptor binding terminology, both receptor and acceptor contain a receptive site for the ligand, although only the receptor induces a biological function. Moreover, the acceptor lacks an endogenous ligand. Many proteins have been described as receptors for toxic Aβ assemblies, implying a designe

  2024-08-05

  

  The molecular mechanisms that mediate the plasticity of the NMJ are not well understood. PGC-1α is a master regulator of the NMJ gene expression program 23, 24, and thus AMPK might indirectly regulate the NMJ via its broad influence on the coactivator. Cerveró et al.[6] recently provided more direct

  Human testicular peritubular Emodin (HTPCs) are also the only human testicular cell type that can be isolated, cultured and studied in vitro (Albrecht et al., 2006, Mayerhofer, 2013). Results from recent studies indicate that their roles go beyond sperm transport and include immunological functions.

  Introduction Myasthenia gravis (MG) is an autoimmune disorder characterized by muscle weakness, which is mainly due to autoantibodies reducing the number or function of postsynaptic NF 449 receptors (AChRs) [1], [2]. Animal models have been developed to uncover the immunopathogenesis of MG. Experim

  AChE variants and their functions The AChE gene generates several splice variants of AChE which are designated as hydrophobic (H), readthrough (R) and tailed (T) forms differing in membrane association and also localisation on a tissue and sub-cellular level. They all undergo significant posttran

  In these experiments, recordings were performed continuously in the homecage and during the first 5 days of training on a randomized forced alternation T-maze working memory task (Figures 1A, 1B, 3A, and 3B) (Kucewicz et al., 2011). Sleep and wake states were determined by simultaneous recording of

  In patients with spina bifida and spinal cord injury, fecal incontinence is a serious issue that can impair activities of daily living and patient self-esteem. To address this Malone et al. first described the Antegrade Continence Enema (ACE) procedure in 1990 [1], which achieves continence by all

  In addition to pH regulation by ion (counter-) fluxes, acidification is regulated by the abundance of V-ATPase on organelles, by the pumping activity of the complex and by proton leakage. In yeast, the V-ATPase VO subunit a is the only subunit expressed in two isoforms termed Stv1p and Vph1p. V-ATPa

  A disruption of lung barrier function caused by PM2.5 has been observed in our experiments; however the underlying mechanism has not been investigated. Zhao et al.
