Directing the self-assembly of tumour spheroids by bioprinting cellular heterogeneous models within alginate/gelatin hydrogels
(2017-07)"Human tumour progression is a dynamic process involving diverse biological and biochemical events such as genetic mutation and selection in addition to physical, chemical, and mechanical events occurring between cells and ... -
Effects of catalase on chloroplast arrangement in Opuntia streptacantha chlorenchyma cells under salt stress
(2017-08)"In arid and semiarid regions, low precipitation rates lead to soil salinity problems, which may limit plant establishment, growth, and survival. Herein, we investigated the NaCl stress effect on chlorophyll fluorescence, ... -
Effects of nitrogen-doped multiwall carbon nanotubes on murine fibroblasts
(2015)"The effect of nitrogen-doped multiwall carbon nanotubes (CNx) on the proliferation of NIH-3T3murine fibroblasts is presented. CNTs were dispersed in distillated water and incubated with mammalian cells in order to evaluate ... -
First description of extrafloral nectaries in Opuntia robusta (Cactaceae): Anatomy and ultrastructure
(2018)"To our knowledge, there are no studies about the structure and ecological function of extrafloral nectaries (EFNs) in Opuntia robusta. This is the first description of EFNs in O. robusta, where young spines have an ... -
Genetic mapping identifies loci that influence tomato resistance against Colorado potato beetles
(Nature Publishing Group, 2018)"The Colorado potato beetle (CPB; Leptinotarsa decemlineata Say), the most economically important insect pest on potato (Solanum tuberosum L.), also feeds on other Solanaceae, including cultivated tomato (Solanum lycopersicum ... -
Histone acetyltransferase TGF-1 regulates Trichoderma atroviride secondary metabolism and mycoparasitism
(2018)"Some filamentous fungi of the Trichoderma genus are used as biocontrol agents against airborne and soilborne phytopathogens. The proposed mechanism by which Trichoderma spp. antagonizes phytopathogens is through the release ... -
In vivo evidence for homo- and heterodimeric interactions of Arabidopsis thaliana dehydrins AtCOR47, AtERD10, and AtRAB18
(2017-12)"Dehydrins (DHNs) are intrinsically disordered proteins that play central roles in plant abiotic stress responses; however, how they work remains unclear. Herein, we report the in planta subcellular localization of Arabidopsis ... -
Method for CaOx crystals isolation from plant leaves
(Elsevier, 2022)"Although calcium oxalate (CaOx) crystals are present in many plants they are poorly studied. A possible limitation is the lack of methods for CaOx crystals isolation at high concentration and high purity, which is required ... -
Molecular ruler mechanism and interfacial catalysis of the integral membrane acyltransferase PatA
(AAAS, 2021)"Glycolipids are prominent components of bacterial membranes that play critical roles not only in maintaining the structural integrity of the cell but also in modulating host-pathogen interactions. PatA is an essential ... -
Neo-functionalization in Saccharomyces cerevisiae: a novel Nrg1-Rtg3 chimeric transcriptional modulator is essential to maintain mitochondrial DNA integrity
(The Royal Society, 2023)In Saccharomyces cerevisiae, the transcriptional repressor Nrg1 (Negative Regulator of Glucose-repressed genes) and the ?-Zip transcription factor Rtg3 (ReTroGrade regulation) mediate glucose repression and signalling from ... -
Sequence analysis and confirmation of the type IV pili-associated proteins PilY1, PilW and PilV in Acidithiobacillus thiooxidans
(Public Library of Science, 2019)"Acidithiobacillus thiooxidans is an acidophilic chemolithoautotrophic bacterium widely used in the mining industry due to its metabolic sulfur-oxidizing capability. The biooxidation of sulfide minerals is enhanced through ... -
Structural insights into the IgE mediated responses induced by the allergens Hev b 8 and Zea m 12 in their dimeric forms
(2016-09)"Oligomerization of allergens plays an important role in IgE-mediated reactions, as effective crosslinking of IgE-Fc epsilon RI complexes on the cell membrane is dependent on the number of exposed B-cell epitopes in a ... -
The Ustilago maydis null mutant strains of the RNA-binding protein UmRrm75 accumulate hydrogen peroxide and melanin
(Nature Publishing Group, 2019)"Ustilago maydis is a dimorphic fungus that has emerged as a model organism for the study of fungal phytopathogenicity and RNA biology. In a previous study, we isolated the U. maydis UmRrm75 gene. The deletion of the UmRrm75 ... -
Transcriptional signature associated with early rheumatoid arthritis and healthy individuals at high risk to develop the disease
(Public Library of Science, 2018)"Background Little is known regarding the mechanisms underlying the loss of tolerance in the early and preclinical stages of autoimmune diseases. The aim of this work was to identify the transcriptional profile and ... -
Voltage-Dependent Protonation of the Calcium Pocket Enable Activation of the Calcium-Activated Chloride Channel Anoctamin-1 (TMEM16A)
(Nature Publishing Group, 2020)"Anoctamin-1 (ANO1 or TMEM16A) is a homo-dimeric Ca2+-activated Cl? channel responsible for essential physiological processes. Each monomer harbours a pore and a Ca2+-binding pocket; the voltage-dependent binding of two ...
