Iron Regulation and the Cell Cycle: identification of an iron-responsive element in the 3′-untranslated region of human cell division cycle 14a mrna by a refined microarray-based screening strategy
(The Journal of Biological Chemistry, 2006)Iron regulatory proteins (IRPs) 1 and 2 post-transcriptionally control mammalian iron homeostasis by binding to iron-responsive elements (IREs), conserved RNA stem-loop structures located in the 5′- or ... -
Modeling cell adhesion and proliferation: a cellular-automata based approach
(Advanced Modeling and Simulation in Engineering Sciences, 2015)Background: Cell adhesion is a process that involves the interaction between the cell membrane and another surface, either a cell or a substrate. Unlike experimental tests, computer models can simulate ... -
Hormone-induced repression of genes requires BRG1-mediated H1.2 deposition at target promoters
(The EMBO Journal, 2016)Eukaryotic gene regulation is associated with changes in chromatin compaction that modulate access to DNA regulatory sequences relevant for transcriptional activation or repression. Although much is ... -
ADP-ribose–derived nuclear ATP synthesis by NUDIX5 is required for chromatin remodeling
(Science, 2016)Key nuclear processes in eukaryotes, including DNA replication, repair, and gene regulation, require extensive chromatin remodeling catalyzed by energy-consuming enzymes. It remains unclear how the ATP ... -
Simplified qualitative discrete numerical model to determine cracking pattern in brittle materials by means of finite element method
(Mathematical Problems in Engineering, 2017)This paper presents the formulation, implementation, and validation of a simplified qualitative model to determine the crack path of solids considering static loads, infinitesimal strain, and plane ... -
Functional characterization of a novel non-coding mutation “Ghent +49A > G” in the iron-responsive element of L-ferritin causing hereditary hyperferritinaemia-cataract syndrome
(Scientific Reports, 2017)Hereditary hyperferritinaemia-cataract syndrome (HHCS) is a rare disorder usually caused by heterozygous mutations in the iron-responsive element (IRE) in the 5′ untranslated region (5′UTR) of the ... -
Unliganded progesterone receptor governs estrogen receptor gene expression by regulating DNA methylation in breast cancer cells
(Cancers, 2018)Breast cancer prognosis and response to endocrine therapy strongly depends on the expression of the estrogen and progesterone receptors (ER and PR, respectively). Although much is known about ERα gene ... -
A simplified scheme for piezoelectric anisotropic analysis in human vertebrae using integral methods
(Mathematical Problems in Engineering, 2018)This paper outlines a computational model for the analysis of the piezoelectric behaviour of the vertebral body remodelling process. Particular attention is paid to the algorithms for the simulation of ... -
Regulation of actin dynamics during structural plasticity of dendritic spines: signaling messengers and actin-binding proteins
(Molecular and Cellular Neuroscience, 2018-09)Activity-dependent plasticity of synaptic structure and function plays an essential role in neuronal development and in cognitive functions including learning and memory. The formation, maintenance and ... -
Rationally designed azobenzene photoswitches for efficient two-photon neuronal excitation
(Nature Communications, 2019)Manipulation of neuronal activity using two-photon excitation of azobenzene photoswitches with near-infrared light has been recently demonstrated, but their practical use in neuronal tissue to photostimulate ... -
Improved dynamical particle swarm optimization method for structural dynamics
(Mathematical Problems in Engineering, 2019)A methodology to the multiobjective structural design of buildings based on an improved particle swarm optimization algorithm is presented, which has proved to be very efficient and robust in nonlinear ... -
ATP, Mg2+, nuclear phase separation, and genome accessibility
(Trends in Biochemical Sciences, 2019)Misregulation of the processes controlling eukaryotic gene expression can result in disease. Gene expression is influenced by the surrounding chromatin; hence the nuclear environment is also of vital ... -
Hereditary hyperferritinemia cataract syndrome: ferritin L gene and physiopathology behind the disease - report of new cases
(International Journal of Molecular Sciences, 2021)Hereditary hyperferritinemia-cataract syndrome (HHCS) is a rare disease characterized by high serum ferritin levels, congenital bilateral cataracts, and the absence of tissue iron overload. This disorder ... -
Description of an ultrasound-guided transverse approach to the transversus thoracis plane block and evaluation of injectate spread in canine cadavers
(Animals, 2021)In humans, the aim of the transversus thoracis plane block is to desensitise the intercostal nerves running through this plane, providing analgesia to the anterior chest wall. Our objective was twofold: ... -
New partners identified by mass spectrometry assay reveal functions of NCAM2 in neural cytoskeleton organization
(International Journal of Molecular Sciences, 2021)Neuronal cell adhesion molecule 2 (NCAM2) is a membrane protein with an important role in the morphological development of neurons. In the cortex and the hippocampus, NCAM2 is essential for proper ... -
LoxTnSeq: random transposon insertions combined with cre/lox recombination and counterselection to generate large random genome reductions
