Programmed cell death or apoptosis is a central biological process that is dysregulated in many diseases, including inflammatory conditions and cancer. The detection and quantification of apoptotic cells in vivo is hampered ... -
A functional variant that affects exon-skipping and protein expression of SP140 as genetic mechanism predisposing to multiple sclerosis
(Oxford University Pres, 2015-10-01)Several variants in strong linkage disequilibrium (LD) at the SP140 locus have been associated with multiple sclerosis (MS), Crohn's disease (CD) and chronic lymphocytic leukemia (CLL). To determine the causal polymorphism, ... -
A global survey of CRM1-dependent nuclear export sequences in the human deubiquitinase family
García Santisteban, Iraia; Bañuelos Rodríguez, Sonia ; Rodríguez Pérez, José Antonio (Portland Press LTD, 2012-01-01)
The mechanisms that regulate the nucleocytoplasmic localization of human deubiquitinases remain largely unknown. The nuclear export receptor CRM1 binds to specific amino acid motifs termed NESs (nuclear export sequences). ... -
A key function for microtubule-associated-protein 6 in activity-dependent stabilisation of actin filaments in dendritic spines
; ; Martínez Hernández, José; ; ; ; ; ; ; ; ; ; ; ; ; ; ; (Nature Publishing, 2018-09-17)
Emerging evidence indicates that microtubule-associated proteins (MAPs) are implicated in synaptic function; in particular, mice deficient for MAP6 exhibit striking deficits in plasticity and cognition. How MAP6 connects ... -
A long non-coding RNA that harbors a SNP associated with type 2 diabetes regulates the expression of TGM2 gene in pancreatic beta cells
González Moro, Itziar; ; Sebastián de la Cruz, Maialen ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; (Frontiers Media, 2023-02)
IntroductionMost of the disease-associated single nucleotide polymorphisms (SNPs) lie in non- coding regions of the human genome. Many of these variants have been predicted to impact the expression and function of long ... -
A novel RT-QPCR-based assay for the relative quantification of residue specific m6A RNA methylation
; ; ; ; ; ; Bilbao Catalá, José Ramón (Nature Publishing Group, 2019-12)
N6-methyladenosine (m6A) is the most common and abundant RNA modification. Recent studies have shown its importance in the regulation of several biological processes, including the immune response, and different approaches ... -
A Proteomic Approach for Systematic Mapping of Substrates of Human Deubiquitinating Enzymes
Ramírez Sánchez, Juan Manuel; Prieto Agujeta, Gorka ; ; ; ; Alduntzin Egizurain, Unai ; Osinalde Moraleja, Nerea ; ; ; ; Rodríguez Pérez, José Antonio ; ; ; ; ; Arizmendi Bastarrika, Jesús María ; Mayor Martínez, Ugo (MDPI, 2021-05-03)
The human genome contains nearly 100 deubiquitinating enzymes (DUBs) responsible for removing ubiquitin moieties from a large variety of substrates. Which DUBs are responsible for targeting which substrates remain mostly ... -
A Systematic Approach to Assess the Activity and Classification of PCSK9 Variants
(MDPI, 2021-12-18)Background: Gain of function (GOF) mutations of PCSK9 cause autosomal dominant familial hypercholesterolemia as they reduce the abundance of LDL receptor (LDLR) more efficiently than wild-type PCSK9. In contrast, PCSK9 ... -
Aberrant Synaptic PTEN in Symptomatic Alzheimer's Patients May Link Synaptic Depression to Network Failure
(Frontiers Media, 2021-05-11)In Alzheimer's disease (AD), Amyloid beta (A beta) impairs synaptic function by inhibiting long-term potentiation (LTP), and by facilitating long-term depression (LTD). There is now evidence from AD models that A beta ... -
Accumulated Bending Energy Elicits Neutral Sphingomyelinase Activity in Human Red Blood Cells
López Jiménez, David; ; ; ; ; ; ; ; Goñi Urcelay, Félix María ; Alonso Izquierdo, Alicia (Elservier, 2012-05-02)
[EN] We propose that accumulated membrane bending energy elicits a neutral sphingomyelinase (SMase) activity in human erythrocytes. Membrane bending was achieved by osmotic or chemical processes, and SMase activity was ... -
Actin- regulated Siglec- 1 nanoclustering influences HIV-1 capture and virus- containing compartment formation in dendritic cells
