British Journal of Pharmacology, EarlyView.Blood vascular permeability is a hallmark of cancer and acts as an active driver of metastatic dissemination. Metastasis accounts for the vast majority of cancer deaths, yet most work has focussed on tumour‐intrinsic traits and angiogenesis, while the specific contribution of endothelial barrier regulation to intravasation and extravasation remains ...

Nucleosome wrapping states encode principles of 3D genome organization
Nature CommunicationsNucleosome is the basic structural unit of the genome. During processes like DNA replication and gene transcription, the conformation of nucleosomes undergoes dynamic changes, including DNA unwrapping and rewrapping, as well as histone disassembly and ...

The Journal of biological chemistry, 1995 Assembly and disassembly of the nucleus at mitosis in eukaryotes involves the reversible interaction of chromatin with the nuclear membrane. Previously we have shown that this interaction is regulated by the antagonistic activities of a kinase and a phosphatase. The kinase promotes membrane release while the phosphatase stimulates binding.

Integrated Engineering of CAR‐T Cells for Solid Tumours
Cell Proliferation, EarlyView.Solid tumours pose multifactorial barriers including antigen heterogeneity, immunosuppressive microenvironment, and poor T‐cell trafficking, limiting CAR‐T efficacy compared to hematologic malignancies. Integrated engineering strategies are essential, combining logic‐gated receptors for precision, metabolic‐epigenetic reprogramming for resilience, and ...

Proteostasis of organelles in aging and disease
The FEBS Journal, EarlyView.Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

Biogenesis of TNF‐α‐insights into proteostasis and inflammation
The FEBS Journal, EarlyView.TNF‐α biogenesis, trafficking, and signalling are tightly and reciprocally coupled to cellular proteostasis systems, including ER chaperones and endoplasmic reticulum‐associated degradation. This bidirectional crosstalk determines whether TNF‐α responses are adaptive or proteotoxic.

The Structural Basis of Gene Regulation for DNA Organized as Chromatin
CHIMIA, 2001 DNA in the nucleus of eukaryotic cells is organized in chromatin, a nucleoprotein complex containing roughly half DNA and half protein. The nucleosome is the underlying DNA packaging element in chromatin, repeating approximately every 200 base ...

Stimulating proteasomal degradation in human proteinopathies
The FEBS Journal, EarlyView.The proteasome mediates the degradation of a wide range of proteins. Boosting proteasomal degradation may be beneficial in several disease contexts and can be achieved either by modulating proteasome activity or by improving substrate delivery. Proteasome activity can be enhanced by increasing proteasome abundance, inducing constitutive gate opening ...

CD36‐mediated lipid rewiring in the metabolic adaptation of tumour ecosystems
The FEBS Journal, EarlyView.Nutrient deprivation drives a lipid‐centric shift in tumour metabolic symbiosis and signalling network. CD36 functions as a bidirectional bridge, transferring fatty acids from stromal donors (adipocytes, CAFs) to the ecosystem tumour‐ and microenvironment‐dependently.
