Journal ArticleDOI
Vitamin C uptake and recycling among normal and tumor cells from the central nervous system.
Allisson Astuya,Teresa Caprile,Maite A. Castro,Katterine Salazar,María de los Angeles García,Karin Reinicke,Federico Rodríguez,Juan Carlos Vera,Carola Millán,Viviana Ulloa,Marcela Low,Fernando Martínez,Francisco Nualart +12 more
TL;DR: Functional uptake analyses support the hypothesis that astrocytes are involved in vitamin C recycling in the nervous system by avoiding the hydrolysis of dehydroascorbic acid produced by antioxidative protection.
Journal ArticleDOI
Brain Glucose-Sensing Mechanism and Energy Homeostasis.
Antonio J. López-Gambero,Antonio J. López-Gambero,Fernando Martínez,Katterine Salazar,Manuel Cifuentes,Francisco Nualart +5 more
TL;DR: The aim of this review focuses on integrating the current understanding of various glucose-sensing mechanisms described in the brain, thereby establishing a relationship between neuroanatomy and control of physiological processes involved in both metabolic and energy balance.
Journal ArticleDOI
Vitamin C Transporters, Recycling and the Bystander Effect in the Nervous System: SVCT2 versus Gluts.
Francisco Nualart,Mack L,Andrea García,Pedro Cisternas,Ernesto R. Bongarzone,Heitzer M,Nery Jara,Fernando Martínez,Luciano Ferrada,Francisca Espinoza,Baeza,Katterine Salazar +11 more
TL;DR: This review will compare the molecular and structural aspects of vitamin C and glucose transporters and their expression in endothelial or choroid plexus cells, which form part of the blood-brain barrier and blood-cerebrospinal fluid (CSF) barrier, respectively and describe SVCT and GLUT expression in different cells of the brain.
Journal ArticleDOI
The Na+-dependent L-ascorbic acid transporter SVCT2 expressed in brainstem cells, neurons, and neuroblastoma cells is inhibited by flavonoids.
Teresa Caprile,Katterine Salazar,Allisson Astuya,Pedro Cisternas,Carmen Silva-Alvarez,Hernán Montecinos,Carola Millán,María de los Angeles García,Francisco Nualart +8 more
TL;DR: The data demonstrates that brain cortex and cerebellar stem cells, neurons and neuroblastoma cells express SVCT2, and the ability of different flavonoids to inhibit AA uptake in normal or immortalized neurons is shown.
Journal ArticleDOI
The oxidized form of vitamin C, dehydroascorbic acid, regulates neuronal energy metabolism
Pedro Cisternas,Carmen Silva-Alvarez,Fernando Martínez,Emilio Fernández,Luciano Ferrada,Karina Oyarce,Katterine Salazar,Juan P. Bolaños,Francisco Nualart +8 more
TL;DR: DHA is a novel modulator of neuronal energy metabolism by facilitating the utilization of glucose through the PPP for antioxidant purposes by stimulating the rate of lactate uptake by neurons in a time‐ and dose‐dependent manner.
