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 ... -
BAX and BAK - the deadly rings. A comprehensive study of the mitochondrial apoptotic pore in situ with super-resolution microscopy
(2023-02-23)Apoptosis, the most common form of cell death in the human body, is essential for numerous physiological processes. The intrinsic apoptosis pathway can be triggered by a wide variety of stimuli and leads to the insertion ... -
Mild production of reactive oxygen species reversibly affects the metabolism and function of the heart
(2023-01-25)Reactive oxygen species (ROS) are molecular oxygen derivatives that are produced as an attribute of aerobic life. The relationship between elevated levels of ROS and heart failure (HF) has been extensively studied. However, ... -
Differentiation-Induced Rearrangement of the Mitochondrial Calcium Uniporter Complex Regulates T-Cell-Mediated Immunity
(2023-01-20)CD4+ T-cells are an important cell type involved in proper mediation of the human adaptive immune system. Activation of CD4+ T-cells is a regulated process which includes a tightly controlled cytosolic calcium (Ca2+) ... -
Optimization of the RT-QuIC in prion disease diagnostic
(2023-01-11)In the present work, we were interested in applying different recombinant prion proteins (rec PrP) as substrates in the real-time quaking-induced conversion (RT-QuIC) assay to improve the diagnostic accuracy in different ... -
Novel therapeutic approaches to treat inflammatory conditions with glucocorticoid and calciferol nanoparticles in vivo and in vitro
(2023-01-10)The body is constantly confronted with environmental threats and sometimes the entry of pathogens leads to severe inflammatory conditions such as sepsis or acute lung injury (ALI). Both diseases are characterized by a ... -
The role of the receptor tyrosine kinase-like orphan receptors (RORs) in human breast cancer
(2022-12-05)Breast and colorectal cancers are among the most common tumor types worldwide and the occurrence of metastases is often associated with a shortened lifespan. One of the signaling pathways that has been frequently ... -
In vivo application of CRISPR/Cas9 mediated gene re-expression in the failing mouse and human myocardium
(2022-11-17)Transcriptional adaptation in cardiomyocytes precedes cellular deterioration and functional decline upon myocardial stress and damage resulting in heart failure progression. The re-activation of WNT/β-catenin (CTNNB1) ... -
Interfering with critical steps of the viral replication cycle to diminish SARS-CoV-2 propagation
(2022-10-07)The ongoing COVID-19 pandemic, caused by the novel coronavirus SARS-CoV-2, has so far infected more than 0.5 billion people worldwide, with at least 6.3 million deaths, and constitutes one of the largest global health ... -
Gene-expression control in early and late-onset dementia
(2022-10-05)Mutations in genes that control epigenetic gene expression, especially the machinery that controls Histone 3 lysine 4 (H3K4me) methylation, are over-represented in intellectual disability disorders. It is mediated by both ... -
HID1 as a novel disease-causing gene in early onset neurological disorders: molecular, functional and phenotypic studies
(2022-09-07)Rare neurological diseases with genetic causes are gaining relevance for child morbidity and mortality due to improvements in health care, prevention and treatment of conventional life-limiting diseases in infants. Emerging ... -
Cellular response to compartmentalized redox alterations
(2022-08-24)Reactive oxygen species (ROS) were considered only as toxic and unavoidable by-products of aerobic cell life in the past. Nevertheless, their significance for cellular signalling is currently widely accepted and extensively ... -
The role of the Glucocorticoid Receptor in intestinal inflammation and tumorigenesis in a murine model of colitis and colitis-associated colorectal cancer
(2022-08-12)Ulcerative colitis (UC) is a life-threatening disease with constantly increasing incidence. Glucocorticoids (GCs) are one of the first choices for the treatment of this disease thanks to their anti-inflammatory action and ... -
Investigating the role of neutral sphingomyelinases in membrane vesicle trafficking
(2022-07-21)Evidence collected over the years has established small extracellular vesicle (sEV) or exosome secretion as a novel paradigm for intercellular communication under both physiological and pathological conditions. SEVs ... -
TP53-status dependent oncogenic EZH2 Activity in Pancreatic Cancer
(2022-07-14)Pancreatic Ductal Adenocarcinoma (PDAC) remains a dismal malignancy with a 5-year sur-vival rate of less than 10%. Predominately, chemoresistance mediated by the dynamic cel-lular plasticity induced through epigenetic ... -
Investigating how peripheral myelin-specific antibodies contribute to central nervous system demyelination – implications for future therapeutical approaches
(2022-07-14)The discovery of peripheral autoantibodies against myelin oligodendrocyte glycoprotein (MOG) allowed the delineation of MOG antibody-associated disease (MOGAD) from other central nervous system (CNS) demyelinating disorders, ... -
Studying the role of coenzyme Q10 in mitochondrial calcium and redox signaling
(2022-06-30)Mitochondria can take up large amounts of calcium (Ca2+) in order to control the activity of several enzymes and their bioenergetics output. As a consequence of this metabolic flux, reactive oxygen species (ROS) are generated ... -
Structure and molecular function of WD-40 repeat-containing autophagy proteins Atg18, Atg21 and Hsv2
(2022-06-23)Autophagy is a highly regulated cellular degradation and recycling process conserved from yeast to higher eukaryotes. This process is constitutively active at a low level, and non-selectively degrades portions of the cytosol ... -
Effect of CLN3-loss-of-function on cellular metabolism and signalling
(2022-06-20)Since a coordinated function of all organelles is essential for the proper health of a eukaryotic cell, a defect in a single organelle can affect the condition of other organelles. For instance, mitochondrial dysfunction ... -
