Endoplasmic reticulum stress leads to accumulation of wild-type SOD1 aggregates associated with sporadic amyotrophic lateral sclerosis
(NATL ACAD SCIENCES, 2018)Abnormal modifications to mutant superoxide dismutase 1 (SOD1) are linked to familial amyotrophic lateral sclerosis (fALS). Misfolding of wild-type SOD1 (SOD1(WT)) is also observed in postmortem tissue of a subset of ... -
Enhanced Activity of Exportin-1/CRM1 in Neurons Contributes to Autophagy Dysfunction and Senescent Features in Old Mouse Brain
(HINDAWI LTD, 2021-08-16)Brain aging is characterized by dysfunctional autophagy and cellular senescence, among other features. While autophagy can either promote or suppress cellular senescence in proliferating cells, in postmitotic cells, such ... -
Filtering of Data-Driven Gene Regulatory Networks Using Drosophila melanogaster as a Case Study
(FRONTIERS MEDIA SA, 2021-07-28)Gene Regulatory Networks (GRNs) allow the study of regulation of gene expression of whole genomes. Among the most relevant advantages of using networks to depict this key process, there is the visual representation of large ... -
Fishing forward and reverse: Advances in zebrafish phenomics
(ELSEVIER, 2018)Understanding how the genome instructs the phenotypic characteristics of an organism is one of the major scientific endeavors of our time. Advances in genetics have progressively deciphered the inheritance, identity and ... -
GERO Cohort Protocol, Chile, 2017-2022: Community-based Cohort of Functional Decline in Subjective Cognitive Complaint elderly
(BioMed Central Ltd., 2020-12)BackgroundWith the global population aging and life expectancy increasing, dementia has turned a priority in the health care system. In Chile, dementia is one of the most important causes of disability in the elderly and ... -
Herpes simplex virus type 1 neuronal infection perturbs golgi apparatus integrity through activation of src tyrosine kinase and Dyn-2 GTPase
(Frontiers Media S.A., 2017)Herpes simplex virus type 1 (HSV-1) is a ubiquitous pathogen that establishes a latent persistent neuronal infection in humans. The pathogenic effects of repeated viral reactivation in infected neurons are still unknown. ... -
Homozygous mutation in CEP19, a gene mutated in morbid obesity, in Bardet-Biedl syndrome with predominant postaxial polydactyly
(BMJ PUBLISHING GROUP, 2018)Background Bardet-Biedl syndrome (BBS) is a ciliopathy with extensive phenotypic variability and genetic heterogeneity. We aimed to discover the gene mutated in a consanguineous kindred with multiple cases of a BBS phenotype. ... -
Hormetic-Like Effects of L-Homocysteine on Synaptic Structure, Function, and Aβ Aggregation
(MDPI Multidisciplinary Digital Publishing Institute, 2020-02)Alzheimer's Disease (AD) is the primary cause of dementia among the elderly population. Elevated plasma levels of homocysteine (HCy), an amino acid derived from methionine metabolism, are considered a risk factor and ... -
Idiopathic inflammatory myopathy human derived cells retain their ability to increase mitochondrial function
(Public Library of Science, 2020-11)Idiopathic Inflammatory Myopathies (IIMs) have been studied within the framework of autoimmune diseases where skeletal muscle appears to have a passive role in the illness. However, persiting weakness even after resolving ... -
IL-22-expressing CD4(+)AhR(+) T lymphocytes are associated with RANKL-mediated alveolar bone resorption during experimental periodontitis
(Blackwell Munksgaard, 2019-10)Background and Objective Over the past few years, the importance of interleukin-22 (IL-22) and T-helper (Th)22 lymphocytes in the pathogenesis of periodontitis has become apparent; however, there are still aspects that are ... -
Implications of Selective Autophagy Dysfunction for ALS Pathology
(MDPI Multidisciplinary Digital Publishing Institute, 2020-02)Amyotrophic lateral sclerosis (ALS) is a lethal neurodegenerative disorder that progressively affects motor neurons in the brain and spinal cord. Due to the biological complexity of the disease, its etiology remains unknown. ... -
In the Right Place at the Right Time: Regulation of Cell Metabolism by IP3R-Mediated Inter-Organelle Ca2+ Fluxes
(FRONTIERS MEDIA SA, 2021-03-22)In the last few years, metabolism has been shown to be controlled by cross-organelle communication. The relationship between the endoplasmic reticulum and mitochondria/lysosomes is the most studied; here, inositol ... -
In Vitro Analysis of the Role of Schwann Cells on Axonal Degeneration and Regeneration Using Sensory Neurons from Dorsal Root Ganglia
(Humana Press, 2018)Sensory neurons from dorsal root ganglion efficiently regenerate after peripheral nerve injuries. These neurons are widely used as a model system to study degenerative mechanisms of the soma and axons, as well as regenerative ... -
