Advanced Science, EarlyView.Prolonged exposure to stiff extracellular matrix drives cancer‐associated fibroblasts into a persistently activated myofibroblast state. Two parallel pathways are identified: β1 integrin activation smoothens the nuclear lamina to reduce lamin–chromatin contacts, while the formin mDia2 regulates nuclear actin to alter chromatin organization.

Supramolecular Composite Materials from Cellulose, Chitosan, and Cyclodextrin: Facile Preparation and Their Selective Inclusion Complex Formation with Endocrine Disruptors [PDF]
, 2013 We have successfully developed a simple one-step method of preparing high-performance supramolecular polysaccharide composites from cellulose (CEL), chitosan (CS), and (2,3,6-tri-O-acetyl)-α-, β-, and γ-cyclodextrin (α-, β-, and γ-TCD).

Advanced Science, EarlyView.The authors engineer colorectal cancer cells with reduced redundancy of UHRF1 and DNMT1, key DNA methylation maintenance factors, lowering the maintenance threshold and sensitizing cells to inhibition. They develop reporter assays driven by endogenous tumor‐suppressor gene promoters with enhanced sensitivity and dynamic range to demethylating drugs ...

Angewandte Chemie, EarlyView.A modular strategy was developed to synthesize tri‐, hexa‐, and nona‐saccharides representing repeating units of the conserved O‐polysaccharide backbone of Salmonella. Conjugates of these glycans to bacteriophage Qβ induced strong IgG responses in mice and rabbits. Antibodies elicited recognized native O‐polysaccharides and conferred protection against

Characterization of Sirt2 using conditional RNAi in mice [PDF]
, 2011 Within the past eight years, RNA interference (RNAi) has emerged as a powerful experimental tool for gene function analysis in mice. Reversible control of shRNA mediated RNAi has been achieved by using a tetracycline (tet)-inducible promoter.

Advanced Science, EarlyView.Pancreatic neuroendocrine tumors frequently silence MEN1 through epigenetic mechanisms. Here, SIRT7 recruits DNMT1 to the MEN1 promoter, drives hypermethylation, and enhances DNA repair. Inhibiting SIRT7 restores MEN1, reduces MRN complex abundance, impairs double‐strand break repair, and sensitizes PanNET models to radiation, supporting SIRT7 as a ...

FGL2‐HDAC11 Drives Immunothrombosis via NETs‐Mediated Endothelial Capillarization in MASLD Fibrosis
Advanced Science, EarlyView.ABSTRACT Metabolic dysfunction–associated steatotic liver disease (MASLD) is frequently accompanied by hepatic fibrosis and systemic cardiovascular complications; however, the mechanistic interplay between coagulation abnormalities and disease progression remains poorly defined.

Epigenetics in Oncohematology: Brief Review
Клиническая онкогематология, 2015 Objective. To discuss historical aspects of epigenetics as an independent branch of biology, as well as to describe post-translational modifications of DNA and histones (PTMs) as epigenetic events. Methods.

The Journal of Cell Biology, 2005 Many progenitor cell types start differentiation by turning on transcription. But on page 577, Shen et al. show that oligodendrocytes (OLs)—the myelin-forming cells of the nervous system—require a general transcriptional shutdown for differentiation.The transcriptional slowing is due to histone deacetylation, which compacts chromatin.
