MetabolomicsMitochondrial metabolism sustains DNMT3A-R882-mutant clonal haematopoiesis
Somatic DNMT3A R882 codon mutations drive the most common form of clonal haematopoiesis (CH) and are associated with increased acute myeloid leukaemia (AML) risk1,2. Preventing expansion of DNMT3A-R882-mutant haematopoietic stem/progenitor cells (HSPCs) may therefore avert progression to AML. To ide...

MetabolomicsFasudil may alleviate alcohol-induced astrocyte damage by modifying lipid metabolism, as determined by metabonomics analysis

Alcohol dependence is a chronic, relapsing encephalopathy characterized by compulsive craving for alcohol, loss of control over alcohol use, and the presence of negative emotions and physical discomfort when alcohol is unavailable. Harmful use of alcohol is one of the greatest risk factors for de...

TranscriptomicsExpression data from low R:FR - SA crosstalk in Arabidopsis
Low R:FR signaling through phytochromes induces shade avoidance responses, including petiole elongation. Salicylic acid-mediated defense against pathogens is inhibited under these conditions. Using microarrays we studied the crosstalk between low R:FR and SA at the global gene expression level in Ar...

TranscriptomicsExpression data from low R:FR - JA crosstalk in Arabidopsis
Low reduced red:far-red ratio [R:FR] signaling through phytochromes induces shade avoidance responses, including petiole elongation. Jasmonic acid-mediated defense against herbivores and pathogens is inhibited under these conditions. Using microarrays we studied the crosstalk between low R:FR and JA...

TranscriptomicsPromoter hypermethylation in MLL-r leukemia: biology and therapeutic targeting
MLL-r infant acute lymphoblastic leukemia (ALL) has largely unclear oncogenesis. It has been shown unrelated to copy number change or mutations in the tyrosine kinome. We therefore, explored the possible role of genome wide CpG island hypermethylation in MLL-r infant ALL. We employed the HpaII-ti...

TranscriptomicsR-loops are marks for histone H3 Ser10 phosphorylation and chromatin compaction
R-loops are transcription by-products that may constitute a threat to genome integrity. In addition to specific enzymes to remove them, eukaryotes rely on a number of mRNP biogenesis factors such as the THO complex, to prevent co-transcriptional R-loop formation. We show in Saccharomyces cerevisiae ...

GenomicsR-loops induce repressive chromatin marks over mammalian gene terminators
The formation of R-loops is a natural consequence of the transcription process, caused by invasion of the DNA duplex by nascent transcripts. These structures have been considered rare transcriptional by-products with potential harmful effects on genome integrity, due to the fragility of the displace...

MetabolomicsComparative Metabolomic Sampling of Upper and Lower Airways by Four Different Methods to Identify Biochemicals That May Support Bacterial Growth
Bacteria need nutrients from the host environment to survive, yet we know little about which biochemicals are present in the airways (the metabolome), which of these biochemicals are essential for bacterial growth and how they change with airway disease. The aims of this pilot study were to develop ...

Metabolomics1H NMR Urinary Metabolomic Analysis in Older Adults after Hip Fracture Surgery May Provide Valuable Information for Patient Profiling-A Preliminary Investigation
In these times of precision and personalized medicine, profiling patients to identify their needs is crucial to providing the best and most cost-effective treatment. In this study, we used urine metabolomics to explore the characterization of older adults with hip fractures and to explore the foreca...

TranscriptomicsAntitumor Activity of (R,R’)-4-methoxy-1-naphthylfenoterol in a rat C6 glioma xenograft model in the mouse
(R,R’)-4-methoxy-1-naphthylfenoterol (MNF) inhibits in vitro proliferation of several types of cancer cell lines. In this study, the in vivo antitumor effects of MNF were evaluated using rat C6 glioma cells implanted subcutaneously into the lower flank of 5 week-old NMRI/Nude female Swiss mice. Thre...
