Mutant NPM1 in Acute Myeloid Leukemia Initiation and Maintenance

open access: yesAging and Cancer, EarlyView.
NPM1 mutations drive acute myeloid leukemia by acting as neomorphic transcriptional regulators that cooperate with Menin–MLL and XPO1 to sustain HOX/MEIS1 expression and block differentiation. Targeting these mutant‐specific transcriptional dependencies provides a rational therapeutic strategy for NPM1‐mutated AML.

Histone Methyltransferase Assay in vitro

open access: yesBio-Protocol, 2012
Histone methylation is an important epigenetic modification that plays important roles in plant development and growth. Histone methytransferases are the enzymes to establish histone methylation and here we describe a simple and effective protocol for ...

Microenvironmental Reprogramming by 3D Anisotropic Cardiac Extracellular Matrix Induces Nuclear Remodeling and Epigenetic Maturation of Chemically Induced Cardiomyocytes

open access: yesAdvanced Functional Materials, EarlyView.
A 3D anisotropic hydrogel derived from heart extracellular matrix guides cytoskeletal alignment and nuclear remodeling in reprogrammed cardiomyocyte‐like cells. This study reveals how matrix alignment modulates nuclear envelope dynamics and chromatin state, triggering transcriptional and functional maturation.

Cfp1 is required for gene expression dependent H3K4me3 and H3K9 acetylation in embryonic stem cells [PDF]

open access: yes, 2014
BackgroundTrimethylation of histone H3 lysine 4 (H3K4me3) accumulates at promoters in a gene activity dependent manner. The Set1 complex is responsible for most H3K4me3 in somatic cells and contains the conserved subunit Cfp1, which is implicated in ...

Engineering Extracellular Vesicle Production Through Magnetic Ion Channel Activation for Bone Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
Magnetic Ion Channel Activation (MICA) enables remote stimulation of mechanosensitive ion channels using functionalised magnetic nanoparticles, enhancing extracellular vesicle (EV) biogenesis is pre‐osteoblasts. MICA desrived EVs exhibit typical nano‐vesicular characteristics but display superior pro‐osteogeneic activity, promoting mesenchymal stem ...

Cell Cycle Control of Nuclear Metabolism Couples Phosphatidylinositol Signaling to Histone Methylation

open access: yesAdvanced Science, EarlyView.
Nuclear metabolism oscillates during cell cycle progression. Quantitative chromatome proteomics and imaging reveal phase‐specific dynamics of PIP5K1A and nuclear PIP2, linking phosphatidylinositol metabolism to histone methylation. This work identifies nuclear lipid metabolism as a previously unrecognized regulatory axis coordinating chromatin ...

Effect of phenylhexyl isothiocyanate on aberrant histone H3 methylation in primary human acute leukemia

open access: yesJournal of Hematology & Oncology, 2012
Background We have previously studied the histone acetylation in primary human leukemia cells. However, histone H3 methylation in these cells has not been characterized. Methods This study examined the methylation status at histone H3 lysine 4 (H3K4) and
