Alpha-Actinin-4 Supports B Cell Survival by Limiting Lateral BCR Mobility
(2023-10-17)The B cell antigen receptor (BCR) is involved in many cellular processes that define B cell fate. Once engaged by a cognate antigen, the BCR initiates a series of signaling cascades that drive B cell activation, proliferation, ... -
Comparative analysis of the mitochondrial proteome in a mouse model of Rett syndrome
(2023-10-12)Rett syndrome is a neural development disorder. The gene, for culprit protein, MeCP2 (methylated CpG binding protein) is located on chromosome X and the majority of patients are young girls. Rett syndrome patients do not ... -
Mitochondrial nucleoid distribution and its relation to presynaptic activity investigated by correlative light microscopy
(2023-10-11)Mitochondria are essential for eukaryotic life, because they provide most of the energy for a variety of cellular processes. Especially high energy demanding cells and tissues like the muscles and the neuronal cells of the ... -
Knockdown of NEAT1 prevents lipid droplet accumulation in microglia after ischemic stroke via autophagy
(2023-10-06)Lipid droplets (LDs), lipid-storing organelles containing neutral lipids such as glycerolipids and cholesterol, are increasingly accepted as structural markers of inflammation. The nuclear paraspeckle assembly transcript ... -
Characterization of myelin-specific autoantibodies in an EAE mouse model
(2023-10-02)Abstract Autoimmune diseases are caused by an attack of the immune system against own tissues, but the exact effector mechanisms may vary between individual diseases and are not yet fully understood. The autoimmune disease ... -
Evaluation of synergistic hybrid nanoparticles for improved diagnosis and treatment of pancreatic cancer
(2023-09-13)Pancreatic ductal adenocarcinoma (PDAC) has a devastating prognosis with no effective treatment options. Several factors contribute to its lethality, including the usually late diagnosis in the already advanced stage and ... -
High throughput strategies for electrophysiological characterisation of cardiomyocytes
(2023-08-22)Personalised medicine describes the customised application of medical treatment at a patient-specific level. This type of precision medicine stratifies patients based on their specific genotype or phenotype for targeted ... -
Alpha-synuclein-associated alterations at the synapse in models of Parkinson’s disease
(2023-08-16)Parkinson’s disease (PD) is one of the most common neurodegenerative disorders that is characterized by the typical motor features, and also by a multiplicity of non-motor symptoms. The main pathological hallmarks of PD ... -
Influence of long-term acid adaptation and acute microenvironmental pH changes on Pancreatic Ductal Adenocarcinoma (PDAC) development, progression and invasion
(2023-08-16)Pancreatic ductal adenocarcinoma (PDAC) is one of the most malignant cancers worldwide and it is predicted to be the second leading cause of cancer-related deaths by 2030. PDAC development is strictly linked to the ... -
Modulation of HSF1 activity by p53 and its impact in cancer therapies
(2023-07-13)The tumor suppressor p53 (TP53) is mutated in ~70 % of colorectal cancer (CRC) cases. Of these cases, approximately 80 % undergo subsequent p53 loss-of-heterozygosity (p53LOH), losing the remaining wildtype p53 (WTp53) ... -
Stereoselectivity in Drug Membrane Transport by Solute Carriers (SLCs)
(2023-07-10)About 50% of all small molecule drugs are racemic mixtures of usually two stereoisomers. In the living organism, these drugs interact with a mostly chiral environment of unichiral amino acids, sugars, hormones, and other ... -
The Role of Heat Shock Protein A4 (HSPA4) in the Heart
(2023-07-07)Non-ischemic cardiomyopathies may be caused by genetic mutations but may also result from cytotoxic influences of chemotherapeutic drugs and the accumulation of misfolded proteins. Heat shock protein A4 (HSPA4) ... -
TGFβ mediated chromosomal instability in human colorectal cancer cells
(2023-06-28)Chromosomal instability (CIN) is a major hallmark of human cancer and is defined as persistently high rate of the generation of chromosomal aberrations leading to genetic variability, tumour heterogeneity and tumour ... -
Atrial mitochondrial calcium handling in patients with atrial fibrillation
(2023-05-30)Atrial fibrillation (AF) is the most common form of arrhythmia however, due to the incomplete understanding of its molecular mechanisms, there are several limitations of the currently available therapeutic strategies. ... -
Effects of acute and long-term tachypacing on atrial engineered human myocardium
(2023-04-27)Atrial fibrillation is the most common supraventricular arrhythmia and is associated with molecular remodelling that promotes the maintenance and worsening of the disease. Although extensive research has been performed to ... -
Effects of histone 3.3K27M-mutation on CREB binding protein (CBP/p300)- and bromodomain and extra terminal domain (BET) protein- mediated gene regulation in diffuse intrinsic pontine gliomas (DIPG)
(2023-04-25)Diffuse intrinsic pontine gliomas (DIPG) are incurable pediatric high-grade tumors. The majority of all DIPG carries a mutation in one of the histone 3 genes leading to a substitution of lysine 27 to methionine (H3 K27M) ... -
Cardiac fibroblast phenotype regulation in engineered connective tissues with a special focus on ER adaptation and stress
(2023-03-23)Cardiovascular diseases cause adverse myocardial remodeling due to cardiomyocyte loss and modifications to the extracellular matrix (ECM), which can ultimately lead to contractile dysfunction and pathological cardiac ... -
Cardiac microvascular dysfunction in diabetes mellitus: elucidation of molecular determinants and therapeutic targets
(2023-03-09)Microvascular dysfunction is a pathological hallmark of the diabetic myocardium, and is central to the etiology of diabetes-associated cardiac events. Herein, previous studies highlighted the role of the vasoactive micro-RNA ... -
The MDM2 oncoprotein antagonizes Poly(ADP-ribosyl)ation
(2023-02-23)MDM2 is a target gene product and a negative regulator of the tumor suppressor p53. Additionally, MDM2 interferes with the progression of DNA replication forks. Poly(ADP-Ribose) Polymerase 1 (PARP1) is the main ... -
