(2011)During long-term potentiation (LTP), synapses undergo stable changes in synaptic strength. The molecular memory processes that maintain strength have not been identified. One hypothesis is that the complex formed by the ...
-
(American Society for Biochemistry and Molecular Biology Inc., 2017)© 2017 by The American Society for Biochemistry and Molecular Biology, Inc.Allosteric modulators of pentameric ligand-gated ion channels are thought to act on elements of the pathways that couple agonist binding to channel ...
-
(1986)The inner protein shell of human rotavirus consists of a single polypeptide called VP6 which was removed from the single-shelled virus by treatment with CaCl2, leaving the viral core. The core thus obtained was unable to ...
-
(Springer New York LLC, 2005)Recent studies show that inflammation has an active role in the onset of neurodegenerative diseases. It is known that in response to extracellular insults microglia and/or astrocytes produce inflammatory agents. These ...
-
(WILEY-BLACKWELL, 2012-01)Synaptic function is crucially dependent on the spatial organization of the presynaptic and postsynaptic apparatuses and the juxtaposition of both membrane compartments. This precise arrangement is achieved by a protein ...
-
(Society of Biology of Chile, 2005)The specific signaling connections between the mitogen-activated protein kinases (MAPK) such as c-Jun N-terminal kinase (JNK-1) and phosphatases PP4 and M3/6, affecting the family of early nuclear factors, is complex and ...
-
(Frontiers Media, 2022)Advances in our understanding of cancer biology have contributed to generating different treatments to improve the survival of cancer patients. However, although initially most of the therapies are effective, relapse and ...
-
(1971)Acute infusions of angiotensin II or dog renin into hypophysectomized nephrectomized dogs has no effect on the conversion of corticosterone to aldosterone. This conversion was measured in an isolated mitochondrial fraction ...
-
Role of the RhoA/ROCK pathway in high-altitude associated neonatal pulmonary hypertension in lambs (Amer Physiological Soc, 2016)Exposure to high-altitude chronic hypoxia during pregnancy may cause pulmonary hypertension in neonates, as a result of vasoconstriction and vascular remodeling. We hypothesized that susceptibility to pulmonary hypertension, ...
-
(Wiley, 2017)BackgroundIntrathecal/intracisternal BDNF in rodents produces long-lasting hyperalgesia/allodynia, which implies BDNF plays a role in the establishment and maintenance of central sensitization. Both self-regeneration of ...
-
(BioScientifica Ltd., 2010)Fifty to seventy percent of patients with polycystic ovary syndrome (PCOS) present hyperinsulinemia. On the other hand, reports indicate that forkhead box class O 1 (FOXO1) and peroxisome proliferator-activated receptor-g ...
-
(2013)The endoplasmic reticulum (ER) is a key subcellular compartment involved in the folding and maturation of around one-third of the total proteome. Accumulation of misfolded proteins in the ER lumen engages a signal transduction ...
-
(2011)Using an integrative approach at the whole animal, isolated vessels, and molecular levels, we tested the hypothesis that the llama, a species that undergoes pregnancy under the influence of the chronic hypoxia of high ...
-
(SOC BIOLGIA CHILE, 2006)Thyroid hormone (TH; 3,3,,5-triiodothyronine, T-3) is required for the normal function of most tissues, with major effects on O-2 consumption and metabolic rate. These are due to transcriptional activation of respiratory ...
-
(Universidad de la Frontera, 2016)© 2016, Universidad de la Frontera. All rights reserved. Sonic hedgehog (SHH) is an essential morphogen for the development of neural tube, members and somites. Variations in expression can cause abnormalities in the nervous ...
-
(HINDAWI PUBLISHING CORPORATION, 2006)Alzheimer's disease is the principal cause of dementia throughout the world and the fourth cause of death in developed economies. This brain disorder is characterized by the formation of brain protein aggregates, namely, ...
-
(Elsevier, 2014)One of the properties of bacteria is their capacity to acquire large fragments of genomic DNA from other bacteria or to loose important parts of their own genome. Such fragments include genomic islands (GIs); nine GIs ...
-
(2012)The genomic island 3 (GI-3) shared by Brucella melitensis and Brucella abortus contains 29 genes encoding mostly unknown proteins. Within this island, the open reading frames (ORFs) BAB1_0278 and BAB1_0263 are present, ...
-
(2012)In Latin America, there are about 10-12 million people infected with Trypanosoma cruzi, the agent of Chagas' disease, one of the most important neglected tropical parasitism. Identification of molecular targets, specific ...
