Global signalling network analysis of luminal T47D breast cancer cells in response to progesterone
(Frontiers in Endocrinology, 2022)Background: Breast cancer cells enter into the cell cycle following progestin exposure by the activation of signalling cascades involving a plethora of enzymes, transcription factors and co-factors that ... -
Correlation between physical performance and stabilometric parameters in older adults
(Medicina, 2022)Background and Objectives: Falls are a common and serious threat to the health and independence of older adults. The decrease in functional capacity during aging means an increased risk of falls. To ... -
Interexaminer reliability and validity of quantity of cervical mobility during online dynamic inspection
(Diagnostics, 2022)Background: Physical therapists routinely measure range of motion (ROM) of cervical spine. The reliability of the cervical range of motion (CROM) device has been demonstrated in several studies, but ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Multiple ion scaffold-based delivery platform for potential application in early stages of bone regeneration
(Materials, 2021)Bone has the intrinsic capacity to regenerate itself, as long as the damage is small, through the sequential stimulation of specific phases, such as angiogenesis followed by osteogenesis. However, when ... -
Engineering a genome-reduced bacterium to eliminate Staphylococcus aureus biofilms in vivo
(Molecular Systems Biology, 2021)Bacteria present a promising delivery system for treating human diseases. Here, we engineered the genome-reduced human lung pathogen Mycoplasma pneumoniae as a live biotherapeutic to treat biofilm-associated ... -
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 ... -
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 ... -
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 ... -
Dissociation of functional and structural plasticity of dendritic spines during NMDAR and mGluR-dependent long-term synaptic depression in wild-type and fragile X model mice
(Molecular Psychiatry, 2021)Many neurodevelopmental disorders are characterized by impaired functional synaptic plasticity and abnormal dendritic spine morphology, but little is known about how these are related. Previous work in ... -
Assessing the potential role of copper and cobalt in stimulating angiogenesis for tissue regeneration
(PLoS One, 2021)The use of copper (Cu2+) and cobalt (Co2+) has been described to stimulate blood vessel formation, a key process for the success of tissue regeneration. However, understanding how different concentrations ... -
Maturation of biomimetic hydroxyapatite in physiological fluids: a physicochemical and proteomic study
(Materials Today Bio, 2021-09)Biomimetic calcium-deficient hydroxyapatite (CDHA) as a bioactive material exhibits exceptional intrinsic osteoinductive and osteogenic properties because of its nanostructure and composition, which ... -
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: ... -
LoxTnSeq: random transposon insertions combined with cre/lox recombination and counterselection to generate large random genome reductions
