Ca2+ transfer to mitochondria: a spark of life in unexpected conditions
(Chile. Universidad Mayor, 2020)The inositol 1,4,5-triphosphate receptor (InsP3R)-mediated calcium (Ca2+) transfer to mitochondria is important to maintain mitochondrial respiration and bioenergetics in normal and cancer cells, even though cancer cells ... -
Cancer cells with defective oxidative phosphorylation require endoplasmic reticulum-to-mitochondria Ca2+ transfer for survival
(American Association for the Advancement of Science, 2020-07)Spontaneous Ca2+ signaling from the InsP(3)R intracellular Ca2+ release channel to mitochondria is essential for optimal oxidative phosphorylation (OXPHOS) and ATP production. In cells with defective OXPHOS, reductive ... -
CD73 Ectonucleotidase Restrains CD8+T Cell Metabolic Fitness and Anti-tumoral Activity 1 of 1 CD73 Ectonucleotidase Restrains CD8+T Cell Metabolic Fitness and Anti-tumoral Activity
(FRONTIERS MEDIA SA, 2021-02-18)CD39 and CD73 are ectoenzymes that dephosphorylate ATP into its metabolites; ADP, AMP, and adenosine, and thus are considered instrumental in the development of immunosuppressive microenvironments. We have previously shown ... -
Clinical and pulmonary function analysis in long-COVID revealed that long-term pulmonary dysfunction is associated with vascular inflammation pathways and metabolic syndrome
(Frontiers Media S.A., 2023-10)Introduction: Long-term pulmonary dysfunction (L-TPD) is one of the most critical manifestations of long-COVID. This lung affection has been associated with disease severity during the acute phase and the presence of ... -
Collateral Sprouting of Peripheral Sensory Neurons Exhibits a Unique Transcriptomic Profile
(Humana Press, 2020-10)Peripheral nerve injuries result in motor and sensory dysfunction which can be recovered by compensatory or regenerative processes. In situations where axonal regeneration of injured neurons is hampered, compensation by ... -
Compartmentalized necroptosis activation in excitotoxicity-induced axonal degeneration: a novel mechanism implicated in neurodegenerative disease pathology

Correction: The necroptosis machinery mediates axonal degeneration in a model of Parkinson disease (vol 32, pg 274, 2019)
(Chile. Universidad Mayor, 2020-07)Correction to: Cell Death & Differentiation https://doi.org/10.1038/s41418-019-0408-4. Since online publication of this article, the authors noticed that reference details provided for references 65 and 66 were incorrect. ... -
Decoding Gene Networks Modules That Explain the Recovery of Hymenoglossum cruentum Cav. After Extreme Desiccation
(Frontiers Media S.A., 2020-05)Hymenoglossum cruentum (Hymenophyllaceae) is a poikilohydric, homoiochlorophyllous desiccation-tolerant (DT) epiphyte fern. It can undergo fast and frequent dehydration-rehydration cycles. This fern is highly abundant at ... -
Disulfide cross-linked multimers of TDP-43 and spinal motoneuron loss in a TDP-43A315T ALS/FTD mouse model
(Nature Publishing Group, 2017)Tar DNA binding protein 43 (TDP-43) is the principal component of ubiquitinated protein inclusions present in nervous tissue of most cases of both amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). ... -
Down syndrome and Alzheimer's disease: common molecular traits beyond the amyloid precursor protein
(IMPACT JOURNALS LLC, 2020)Alzheimer's disease (AD) is the most prevalent type of dementia. Down syndrome (DS) is the leading genetic risk factor for Early-Onset AD, prematurely presenting the classic pathological features of the brain with AD. ... -
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 ... -
