Epigenome Alterations and 3D Chromatin Architecture Remodeling in Inflammatory Macrophage Activation under Diabetic Conditions
Aberrant monocyte and macrophage activation in diabetes drives chronic inflammation and complications. While epigenetic mechanisms are implicated, the role of 3D chromatin reorganization remains unclear. Using integrated multi-Omics, we profiled gene expression and 3D chromatin architecture in human CD14+ monocyte differentiated macrophages treated with high glucose plus TNF-alpha (HT) mimicking the diabetic milieu.
Overlooked DNA structures help organize the genome
Overlooked DNA structures help organize the genome Lisa Lock Scientific Editor Robert Egan Associate Editor Northwestern Medicine scientists have discovered that little-studied DNA structures play a central role in organizing the human genome and controlling gene activity, according to a new study published in the Proceedings of the National Academy of Sciences. The study revealed that G-quadruplexes (G4s)—four-stranded DNA structures—directly interact with a key genome-organizing protein...
A prognostic human brain network for diffuse midline glioma
Abstract Diffuse midline gliomas (DMGs) are near-universally lethal tumours of the childhood central nervous system1,2. In animal models, DMGs form brain-wide integrated networks through neuron-to-glioma synapses3,4,5,6 and glioma-to-glioma gap junctional coupling3. This extensive connectivity robustly promotes the growth and invasion of DMG3,4,5,6,7,8,9 and other glial malignancies10,11,12 through paracrine mechanisms and direct neuron-to-glioma synapses.
