Functional interactions between nucleoporins and chromatin [PDF]

Current Opinion in Cell Biology, 2011
As the gatekeepers of the eukaryotic cell nucleus, nuclear pore complexes (NPCs) mediate all molecular trafficking between the nucleoplasm and the cytoplasm. In recent years, transport-independent functions of NPC components, nucleoporins, have been identified including roles in chromatin organization and gene regulation. Here, we summarize our current

Nucleoporin Nup98: a gatekeeper in the eukaryotic kingdoms [PDF]

Genes to Cells, 2010
The nucleoporin Nup98 is an essential component of the nuclear pore complex. This peripheral nucleoporin with its Gly‐Leu‐Phe‐Gly (GLFG) repeat domain contributes to nuclear‐cytoplasmic trafficking, including mRNA export. In addition, accumulating studies indicate that Nup98 plays roles in several important biological events such as gene expression ...

Chromosomal Instability Drives Glioblastoma Heterogeneity and Therapeutic Opportunities

Advanced Science, EarlyView.
ABSTRACT Glioblastoma, the most aggressive and lethal form of brain cancer, is defined by profound genomic instability, with Chromosomal Instability (CIN) playing a central role in driving tumor progression, therapy resistance, and poor prognosis. CIN is characterized by numerical and structural alterations, is driven by mechanisms such as mitotic ...

Prion formation by a yeast GLFG nucleoporin [PDF]

Prion, 2012
The self-assembly of proteins into higher order structures is both central to normal biology and a dominant force in disease. Certain glutamine/asparagine (Q/N)-rich proteins in the budding yeast Saccharomyces cerevisiae assemble into self-replicating amyloid-like protein polymers, or prions, that act as genetic elements in an entirely protein-based ...

Multiscale Architecture and Mechanics of the Cell Nucleus: Implications for Disease, Bioengineering and Nanomedicine

Advanced Science, EarlyView.
Nuclear mechanical properties are inherently scale‐dependent, arising from a hierarchical architecture that spans DNA, chromatin, the nuclear envelope, and condensates. Experimental techniques and theoretical models are integrated into a cohesive multiscale framework linking nanoscale structural features to organelle‐level mechanical behavior.

Mechanical Activation of Piezo1 Drives Osteoarthritis Through Kdm5c‐Mediated Epigenetic Silencing

Advanced Science, EarlyView.
Excessive mechanical stress activates Piezo1, triggering Ca2+‐dependent cytoskeletal forces that deform the nucleus and reduce H3K4me3. Kdm5c demethylates H3K4me3 at Col2a1 and Runx3 promoters. Kdm5c knockout rescues degradation. Repurposed telmisartan directly inhibits Kdm5c, blocking this axis and showing disease‐modifying efficacy in mouse OA models

Linking Nucleoporins, Mitosis, and Colon Cancer [PDF]

Cell Chemical Biology, 2016
Suppression of a nuclear pore protein Nup358/RanBP2 is linked to mitotic cell death, but the clinical relevance of this link is unknown. In a recent issue of Cell, Vecchione et al. (2016) show that in approximately 10% of BRAF-like colorectal cancer (CC) patients, Nup358/RanBP2 is critical for survival.

TDP‐43 Aggregation: The Healthy‐Toxic Balance of the Prion‐Like Domain

Advanced Science, EarlyView.
TDP‐43 function relies on a delicate balance between reversible phase‐separated states and irreversible aggregation. Under physiological conditions, TDP‐43 forms dynamic droplets and oligomers that support normal cellular functions. In pathological contexts, this balance shifts toward aberrant aggregation, leading to toxic species.
