Cell wall stress in yeast triggers transcriptional reprogramming through the CWI pathway. This study identifies Sus1, a subunit of SAGA and TREX‐2, as a key regulator in this process. Sus1 associates with stress‐responsive genes, promoting pre‐initiation complex assembly, chromatin remodeling, and RNA Pol II progression independently of H2B ...

Nucleoporin Gene Fusions and Hematopoietic Malignancies [PDF]
Nuclear pore complexes (NPCs) are the sole gateways between the nucleus and the cytoplasm of eukaryotic cells and they mediate all macromolecular trafficking between these cellular compartments. Nucleocytoplasmic transport is highly selective and precisely regulated and as such an important aspect of normal cellular function. Defects in this process or

Nuclear Envelope Regulation of Oncogenic Processes: Roles in Pancreatic Cancer
Pancreatic cancer is an aggressive and intractable malignancy with high mortality. This is due in part to a high resistance to chemotherapeutics and radiation treatment conferred by diverse regulatory mechanisms.

PP2A-B55SUR-6 promotes nuclear envelope breakdown in C. elegans embryos
Summary: Nuclear envelope (NE) disassembly during mitosis is critical to ensure faithful segregation of the genetic material. NE disassembly is a phosphorylation-dependent process wherein mitotic kinases hyper-phosphorylate lamina and nucleoporins to ...

Intercompartmental communication in senescence
Senescent cells experience structural changes in the plasma membrane, endoplasmic reticulum, mitochondria, lysosomes, nucleus, and cytoskeleton. These alterations disrupt crosstalk among cellular compartments, impairing vesicular trafficking, contact sites, and molecular flow.

Cytoplasmic nucleoporin assemblage: the cellular artwork in physiology and disease
Nucleoporins, essential proteins building the nuclear pore, are pivotal for ensuring nucleocytoplasmic transport. While traditionally confined to the nuclear envelope, emerging evidence indicates their presence in various cytoplasmic structures ...

HIV Nuclear Entry: Clearing the Fog
HIV-1 and other lentiviruses have the unusual capability of infecting nondividing cells, but the mechanism by which they cross an intact nuclear membrane is mysterious.

Tumor metastasis results from complex interactions between cancer cells and mechanical microenvironments. We propose a “nucleus‐centered, cross‐stage mechanical signal decoding” model, highlighting how nuclear mechanosensors interpret forces at different stages.
