Analysis of genetic interactions and hierarchies of Wnt-signaling components in vivo
(2013-02-13)In cooperation with other signaling cascades the Wnt/β-catenin signaling pathway is an essential regulator of embryonic development as well as adult tissue homeostasis and stem cell proliferation. Mutations in components ... -
Analysis of Protein Transport to the Inner Nuclear Membrane
(2019-07-10)The eukaryotic cell is divided into different compartments. The biggest compartment is the nucleus which is formed by one lipid bilayer folded into two membranes: the outer nuclear membrane (ONM) and the inner nuclear ... -
CHARGE syndrome: candidate genes and pathogenesis
(2015-09-25)CHARGE syndrome is a complex malformation syndrome affecting several organ systems like the central nervous system, ear, eye and heart. Heterozygous loss of function mutations in CHD7, a conserved chromatin remodelling ... -
Epigenetic regulation of osteoblast differentiation
(2017-06-07)Proper temporal epigenetic regulation of gene expression is essential for cell fate determination and tissue development. However, epigenetic mechanisms involved in control of bone-specific transcriptional programs remain ... -
Epigenetic Regulation of Tumor Cell Phenotype
(2017-04-03)The Transforming Growth Factor-β (TGFβ)/SMAD signaling pathway can function as either a tumor suppressor or metastasis promoter during tumor progression. In normal epithelial cells and early stages of epithelial ... -
Functional characterization of C/D snoRNA-derived microRNAs
(2018-06-26)miRNAs are essential regulators of cell fate and involved in several human diseases, although their biogenesis is a well-accepted paradigm (microprocessor, Exp5, Dicer, and Argonaute). New evidence revealed different ... -
Gemcitabine Resistance Elicits a Calcium Dependent Epigenetic Reprogramming in Pancreatic Cancer
(2021-03-08)Pancreatic cancer is a dismal malignancy with a 5-year survival rate of 7-9%, one of the worst among all cancer types. Patients with pancreatic ductal adenocarcinoma (PDAC) usually present an advanced stage of the disease ... -
Identification of therapeutic targets in the Burkitt’s lymphoma specific B cell antigen receptor signaling network
(2018-11-12)Burkitt’s lymphoma (BL) is an aggressive B cell neoplasm that is characterized by a chromosomal translocation, which brings the proto-oncogene c-MYC under the control of Immunoglobulin (Ig) enhancer elements leading to ... -
Lysosomal and mitochondrial crosstalk: the role of lysosomal signaling on mitochondrial biogenesis and function
(2018-11-15)Defects in metabolism result in various diseases, with neurodegeneration being one of the most prevalent consequences. Mitochondria and lysosomes are long known to be fundamental for cellular metabolism. In addition to ... -
Mechanisms underlying the temporal and selective induction of Ptf1a target genes
(2019-01-30)The bHLH transcription factor Ptf1a is crucial for the generation of a GABAergic neuronal cell fate over an excitatory glutamatergic fate. Ptf1a is a component of a heterotrimeric transcription factor complex, which in ... -
Microglia activation and regulation of remyelination in the central nervous system
(2019-08-21)In the central nervous system, remyelination requires the proliferation and migration of oligodendrocyte progenitor cells (OPCs) to the lesions, and the differentiation of OPCs into oligodendrocytes that remyelinate the ... -
Molecular and cellular mechanisms of glucocorticoids in the treatment of acute graft-versus-host disease
(2012-11-19)Haematopoietic stem cell transplantation (HSCT) is often the only curative therapy for haematopoietic malignancies and some inherited diseases of the haematopoietic system. A major side effect of HSCT and a cause of morbidity ... -
Molecular characterization of Mst77F and implication in Drosophila spermatogenesis
(2013-04-19)The mechanisms of spermatogenesis, in particular the process of postmeiotic spermatid maturation, are little understood. During this developmental stage massive molecular and morphological rearrangements occur and the major ... -
Myeloid cell-specific ablation of the mineralocorticoid receptor attenuates experimental autoimmune encephalomyelitis
(2013-02-12)The mineralocorticoid receptor (MR) plays an essential role in regulating fluid and electrolyte homeostasis. Amongst hematopoietic cells, also macrophages express the MR but, unlike kidney or colon, they do not co-express ... -
Role of Distal Regulatory Elements in Cancer Progression and Therapy
(2019-01-11)Enhancer elements comprise of regions of DNA that are distal to gene promoters with a characteristic capacity to affect and regulate gene transcription. Enhancers are enriched in a highly context-specific manner allowing ... -
Structural investigation of the histone chaperone complex FACT using genetically encoded crosslinkers in Saccharomyces cerevisiae
(2015-10-23)Chromatin is a highly dynamic nucleoprotein structure that stores the eukaryotic genetic information. Histones are the essential chromatin proteins that form the core octamers around which DNA is compacted within the ... -
Systematic analysis of heterochromatin modification readout
(2017-06-14)Modifications of the building units of chromatin - the histone proteins and DNA - direct the functional readout of the genome and are part of the so called “epigenome” (Fischle et al., 2003b; Kouzarides, 2007). Several ... -
The Cellular Function of USP22 and its Role in Tissue Maintenance and Tumor Formation
(2018-02-12)Colorectal cancer (CRC) is the most frequent malignancy of the gastrointestinal tract and therefore reflects a global health issue. Despite improved detection and treatment options the high mortality and morbidity rates ... -
The role and regulation of histone H2B monoubiquitination during tumorigenesis
(2014-05-23)Posttranslational histone modifications are recognized as important regulators of gene expression. One of them, the monoubiquitination of lysine 120 of histone H2B (H2Bub1), has diverse functions and is involved in gene ... -
