The incidence of type 2 diabetes mellitus (T2DM) is tightly linked to obesity. High levels of circulating glucose and saturated free fatty acids (FFAs), known as glucolipotoxicity (GLT), is implicated in β cell dysfunction and/or death. This study aims to identify miRNAs capable of protecting β cells from GLT-induced cell death (GICD). A library of...
Age-related macular degeneration (AMD) is the leading cause of severe vision loss and blindness in elderly people worldwide. The damage to the retinal pigment epithelium (RPE) triggered by oxidative stress plays a central role in the onset and progression of AMD and results from the excessive accumulation of reactive oxygen species (ROS) produced m...
KMT2A-rearranged acute lymphoblastic leukemia (ALL) in infants (<1 year of age) represents an aggressive type of childhood leukemia characterized by a poor clinical outcome with a survival chance of <50%. Implementing novel therapeutic approaches for these patients is a slow-paced and costly process. Here, we utilized a drug-repurposing strategy to...
MLL-rearranged acute lymphoblastic leukemia (ALL) is characterized by deregulation of the epigenome and shows susceptibility towards epigenetic perturbators such as histone deacetylase (HDAC) inhibitors. Hence, HDACs represent attractive drug targets and a variety of small molecule HDAC inhibitors have been developed and evaluated for the treatment...
Acute lymphoblastic leukemia (ALL) in infants (<1 year of age) remains one of the most aggressive types of childhood hematologic malignancy. The majority (~80%) of infant ALL cases are characterized by chromosomal translocations involving the MLL (or KMT2A) gene, which confer highly dismal prognoses on current combination chemotherapeutic regimens....
MLL‐rearranged acute lymphoblastic leukemia (ALL) represents a highly aggressive ALL subtype, characterized by aberrant DNA methylation patterns. DNA methyltransferase inhibitors, such as decitabine have previously been demonstrated to be effective in eradicating MLL‐rearranged ALL cells in vitro.
Here, we assessed the in vivo anti‐leukemic potenti...
BACKGROUND: Acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML) represent the most common types of cancer among children. Although the survival rates of pediatric ALL and AML have improved substantially over the last decades, the prognosis for some subgroups of pediatric leukemia remain poor. MLL-rearranged infant ALL, MLL-rearrange...
MLL-rearranged acute lymphoblastic leukaemia (ALL) represents an aggressive malignancy in infants (<1 year of age), associated with poor outcome. Current treatment intensification is not further possible, and novel therapy strategies are needed. Notably, MLL-rearranged ALL is characterised by a strongly deregulated epigenome and shows sensitivity t...
Background: Acute Lymphoblastic Leukemia (ALL) in infants is characterized by a high incidence (~80%) of chromosomal rearrangements of the Mixed Lineage Leukemia (MLL) gene, fusing the N-terminal portion of MLL to the C-terminal region of one of its translocation partner genes. MLL-rearranged infant ALL patients are challenged by a very poor progno...
BACKGROUND: MLL-rearranged acute lymphoblastic leukemia (MLLr-ALL) in infants (<1 year of age) represents an aggressive malignancy associated with highly unfavorable outcome. It is characterized by chromosomal translocations involving the MLL gene, with the majority (~80%) of these translocations resulting in the fusion of MLL to either AF4 in t(4;...
BACKGROUND: Infant acute lymphoblastic leukaemia (ALL) is a rare but aggressive malignancy, mainly presenting with chromosomal rearrangements of the MLL (Mixed Lineage Leukaemia) gene locus on 11q23. The majority of these MLL rearrangements involve the translocation partners AF4, AF9 or ENL within the translocation events t(4;11)(q21;q23), t(9;11)(...
Acute lymphoblastic leukemia (ALL) in infants is an aggressive malignancy with a poor clinical outcome, and is characterized by translocations of the Mixed Lineage Leukemia (MLL) gene. Previously, we identified RAS mutations in 14-24% of infant ALL patients, and showed that the presence of a RAS mutation decreased the survival chances even further....
Resistance to glucocorticoids (GCs) remains a major problem in the treatment of infants with acute lymphoblastic leukaemia (ALL) carrying Mixed Lineage Leukaemia (MLL) translocations. Despite intensive research, the mechanism(s) underlying GC resistance remain poorly understood. Recent studies suggested an important role for the pro-survival BCL-2...
Successful treatment results for MLL-rearranged Acute Lymphoblastic Leukemia in infants remain difficult to achieve. Significantly contributing to therapy failure is poor response to glucocorticoids (GCs), like prednisone. Thus, overcoming resistance to these drugs may be a crucial step towards improving prognosis. We defined a gene signature that...
Adenosine monophosphate-activated protein (AMP)-activated kinase (AMPK) is a highly conserved kinase that plays a key role in energy homeostasis. Activation of AMPK was shown to reduce inflammation in response to lipolysaccharide in vitro and in vivo. 5-Aminoimidazole-4-carbox-amide-1-β-d-ribofuranoside (AICAR) is intracellularly converted to the A...
MLL-rearranged infant acute lymphoblastic leukemia (ALL) (<1 year of age) are frequently resistant to glucocorticoids, like prednisone and dexamethasone. As poor glucocorticoid responses are strongly associated with therapy failure, overcoming glucocorticoid resistance may be a crucial step towards improving prognosis. Unfortunately, the mechanisms...
Background:
Gram-positive and gram-negative bacteria are common causative agents of respiratory tract infection. Lipopolysaccharide (LPS) is a component of the gram-negative cell wall and a strong inducer of inflammation. The main proinflammatory component of the gram-positive bacterial cell wall is lipoteichoic acid (LTA). The protein kinase p38...
Objectives:
To study the interplay between serum concentrations of homocysteine, steroid hormones and vitamins B and mutations in 5,10-methylenetetrahydrofolate reductase (MTHFR) gene, in association to Alzheimer's type dementia (ATD).
Design and methods:
Case-control study including 19 individuals diagnosed with ATD and 36 healthy controls. Ser...
