Roles of TIF1β in Leukemic Stem Cell Through SETDB1‐Dependent and Independent Mechanisms

Cancer Science, EarlyView.
In leukemic stem cell, BCR::ABL cooperates with TIF1β to open chromatin at oncogenes and close chromatin at differentiation regulators, driving leukemic reprogramming. In TIF1β‐deficient stem cell, the loss of TIF1β inverts this balance, showing closed chromatin at oncogenes and open chromatin at differentiation regulators.

Pulmonary Vascular Endothelial Cells in Lung Diseases: Mechanisms, Therapeutic Strategies, and Future Directions

Cell Proliferation, EarlyView.
The pathogenic mechanisms of pulmonary vascular endothelial cells (VECs) in lung diseases and their multimodal therapeutic strategies. ABSTRACT Pulmonary vascular endothelial cells (VECs) are essential for the normal function of the lung, through maintaining vascular barrier integrity, regulating blood flow, and participating in inflammatory responses ...

Application Strategies of Bone Marrow Mesenchymal Stromal Cells in Bone‐Related Diseases

Cell Proliferation, EarlyView.
Engineered BMSCs and vesicles enhance therapy effects for bone diseases via multi‐strategic approaches. ABSTRACT Bone‐related diseases (e.g., osteoporosis, osteoarthritis and fractures) exhibit a rising global incidence, imposing significant burdens on both quality of life and healthcare systems.

Nucleation and spreading of a heterochromatic domain in fission yeast

Nature Communications, 2016
Chromosomes contain large heterochromatin domains. Here, the authors measure the kinetics of heterochromatin formation in fission yeast and show both global and local feedbacks by nucleosome-bound enzymes are important for formation and stability of the ...

Vaspin identified as a DNA‐binding serpin with functional consequences for protease inhibition

The FEBS Journal, EarlyView.
Vaspin is a serpin that is expressed in skin, adipose tissue, and liver. It binds to single‐ and double‐stranded DNA with high affinity. This binding is unaffected by mutation of the known heparin‐binding site, accelerates the inhibition of the inflammatory protease KLK7, and may contribute to vaspin's nuclear localization.

A guide to the types, structures, and multifaceted functions of matrix metalloproteinases in cancer

The FEBS Journal, EarlyView.
Matrix metalloproteinases (MMPs) orchestrate cancer progression and metastasis through proteolytic and non‐proteolytic actions. By remodeling the tumor microenvironment, enhancing growth factor availability, and modulating cell behavior, MMPs promote proliferation, migration or invasion, and epithelial‐to‐mesenchymal transition. Alongside extracellular

CHAMP1 complex directs heterochromatin assembly and promotes homology-directed DNA repair

Nature Communications
The CHAMP1 complex, a little-known but highly conserved protein complex consisting of CHAMP1, POGZ, and HP1α, is enriched in heterochromatin though its cellular function in these regions of the genome remain unknown.

Stemness factor Sall4 is required for DNA damage response in embryonic stem cells. [PDF]

, 2015
Mouse embryonic stem cells (ESCs) are genetically more stable than somatic cells, thereby preventing the passage of genomic abnormalities to their derivatives including germ cells. The underlying mechanisms, however, remain largely unclear. In this paper,

Anemia‐associated mutations disrupt the CDIN1‐Codanin1 complex in inherited congenital dyserythropoietic anemia I (CDA‐I) disease

The FEBS Journal, EarlyView.
Congenital dyserythropoietic anemia type I (CDA‐I) arises from mutations in Codanin1 and CDIN1. Using quantitative biophysical approaches, we show that disease‐associated mutations disrupt the CDIN1‐Codanin1 complex. Our findings provide critical insights into the molecular mechanism that links protein dysfunction to disturbing chromatin arrangement ...
