Determination of the number of RAD51 molecules in different human cell lines
(Taylor & Francis, 2019-11-15)Knowledge about precise numbers of specific molecules is necessary for understanding and verification of biological pathways. The RAD51 protein is central in the repair of DNA double-strand breaks (DSBs) by homologous ... -
Excess of rare novel loss-of-function variants in synaptic genes in schizophrenia and autism spectrum disorders
(Springer Nature, 2013-10-15)Schizophrenia (SZ) and autism spectrum disorders (ASDs) are complex neurodevelopmental disorders that may share an underlying pathology suggested by shared genetic risk variants. We sequenced the exonic regions of 215 genes ... -
Expansions of CAG·CTG repeats in immortalized human astrocytes.
(Oxford University Press, 2007)Expansions of trinucleotide repeats (TNRs) are the genetic cause for a number of neurodegenerative disorders. In some of these diseases, ongoing somatic expansions in the brain are thought to contribute to disease progression. ... -
Generation of rationally-designed nerve growth factor (NGF) variants with receptor specificity
(Elsevier, 2017-11-03)Nerve growth factor (NGF) is the prototypic member of the neurotrophin family and binds two receptors, TrkA and the 75 kDa neurotrophin receptor (p75NTR), through which diverse and sometimes opposing effects are mediated. ... -
Genes influenced by MEF2C contribute to neurodevelopmental disease via gene expression changes that affect multiple types of cortical excitatory neurons
(Oxford University Press (OUP), 2020-09-25)Myocyte enhancer factor 2 C (MEF2C) is an important transcription factor during neurodevelopment. Mutation or deletion of MEF2C causes intellectual disability (ID) and common variants within MEF2C are associated with ... -
Genes regulated by BCL11B during T‐cell development are enriched for de novo mutations found in schizophrenia patients
(Wiley, 2020-07-29)While abnormal neurodevelopment contributes to schizophrenia (SCZ) risk, there is also evidence to support a role for immune dysfunction in SCZ.BCL11B, associated with SCZ in genome-wide association study (GWAS), is a ... -
HSP72 Protects Cells from ER Stress-induced Apoptosis via Enhancement of IRE1¿-XBP1 Signaling through a Physical Interaction
(2010)Endoplasmic reticulum (ER) stress is a feature of secretory cells and of many diseases including cancer, neurodegeneration, and diabetes. Adaptation to ER stress depends on the activation of a signal transduction pathway ... -
An inherited duplication at the gene p21 Protein-Activated Kinase 7 (PAK7) is a risk factor for psychosis
(Oxford University Press (OUP), 2014-01-28)Identifying rare, highly penetrant risk mutations may be an important step in dissecting the molecular etiology of schizophrenia. We conducted a gene-based analysis of large (>100 kb), rare copy-number variants (CNVs) in ... -
Inhibition of human BK polyomavirus replication by small noncoding RNAs
(American Society for Microbiology Journals, 2011)Small noncoding RNAs regulate a variety of cellular processes, including genomic imprinting, chromatin remodeling, replication, transcription, and translation. Here, we report small replication-regulating RNAs (srRNAs) ... -
The integrated stress response
(EMBO Press, 2016-09-14)In response to diverse stress stimuli, eukaryotic cells activate a common adaptive pathway, termed the integrated stress response (ISR), to restore cellular homeostasis. The core event in this pathway is the phosphorylation ... -
Kinetics in signal transduction pathways involving promiscuous oligomerizing receptors can be determined by receptor specificity: Apoptosis induction by TRAIL
(American Society for Biochemistry and Molecular Biology, 2012)Here we show by computer modeling that kinetics and outcome of signal transduction in case of hetero-oligomerizing receptors of a promiscuous ligand largely depend on the relative amounts of its receptors. Promiscuous ... -
Mechanisms of ER Stress-Mediated Mitochondrial Membrane Permeabilization
(2010)During apoptosis, the process of mitochondrial outer membrane permeabilization (MOMP) represents a point-of-no-return as it commits the cell to death. Here we have assessed the role of caspases, Bcl-2 family members and ... -
Methods for Monitoring Endoplasmic Reticulum Stress and the Unfolded Protein Response
(2010)The endoplasmic reticulum (ER) is the site of folding of membrane and secreted proteins in the cell. Physiological or pathological processes that disturb protein folding in the endoplasmic reticulum cause ER stress and ... -
Mrc1, Tof1 and Csm3 inhibit CAG·CTG repeat instability by at least two mechanisms
(Springer, 2008)Trinucleotide repeats frequently expand and contract in humans and model organisms. Protein factors that modulate this process have been found by candidate gene approaches or mutant screens for increased expansion ... -
Nerve growth factor (NGF)-mediated regulation of p75(NTR) expression contributes to chemotherapeutic resistance in triple negative breast cancer cells
(Elsevier, 2016)Triple negative breast cancer [TNBC] cells are reported to secrete the neurotrophin nerve growth factor [NGF] and express its receptors, p75 neurotrophin receptor [p75(NTR)] and TrkA, leading to NGF-activated pro-survival ... -
Nerve Growth Factor in Cancer Cell Death and Survival
(MDPI, 2011-02)One of the major challenges for cancer therapeutics is the resistance of many tumor cells to induction of cell death due to pro-survival signaling in the cancer cells. Here we review the growing literature which shows that ... -
Nerve growth factor-mediated inhibition of apoptosis post-caspase activation is due to removal of active caspase-3 in a lysosome-dependent manner
(Nature Publishing Group, 2014-05-01)Nerve growth factor (NGF) is well characterised as an important pro-survival factor in neuronal cells that can inhibit apoptotic cell death upstream of mitochondrial outer membrane permeabilisation. Here we addressed the ... -
Neuronal cell death in neurodegenerative diseases: recurring themes around protein handling
(Wiley, 2008-06-27)Neuronal cell death plays a role in many chronic neurodegenerative diseases with the loss of particular subsets of neurons. The loss of the neurons occurs during a period of many years, which can make the mode(s) of cell ... -
Neurotrophins and B-cell malignancies
(Springer Verlag, 2015-09-23)Neurotrophins and their receptors act as important proliferative and pro-survival factors in a variety of cell types. Neurotrophins are produced by multiple cell types in both pro and mature forms, and can act in an autocrine ... -
