Epstein‐Barr Virus Expressed Long Non‐Coding RNA (lncBARTs) Regulate EBV Latent Genome Replication

Advanced Science, EarlyView.
EBV produces abundant level of lncBARTs, which are essential for maintaining viral genome replication in EBV‐associated cancers. LncBARTs interact with a complex comprising BRD4, CTCF and viral protein EBNA1 at EBV oriP region. This interaction tethers oriP to host chromosomes, facilitating EBV episome replication.

Unveiling an Arpp-19 phosphorylation switch that grants chromosome stability

Communications Biology
During cell division, the onset of mitosis is granted by activation of cyclin B-dependent kinase 1 (Cdk1), master mitotic kinase, coordinated with inactivation of Cdk1-counteracting phosphatases.

Deficiency of mastl, a mitotic regulator, results in cell detachment from developing tissues of zebrafish embryos

Frontiers in Cell and Developmental Biology
To form tissues with unique functions and structures, it is important that the cells that comprise them maintain physical contact. On the other hand, with each mitosis, drastic changes in cell shapes, cell adhesion, and cytoskeletal architecture may ...

A simple biophysical model emulates budding yeast chromosome condensation

eLife, 2015
Mitotic chromosomes were one of the first cell biological structures to be described, yet their molecular architecture remains poorly understood. We have devised a simple biophysical model of a 300 kb-long nucleosome chain, the size of a budding yeast ...

The distribution of cytoplasmic microtubules throughout the cell cycle of the centric diatom Stephanopyxis turris: their role in nuclear migration and positioning the mitotic spindle during cytokinesis. [PDF]

, 1986
The cell cycle of the marine centric diatom Stephanopyxis turris consists of a series of spatially and temporally well-ordered events. We have used immunofluorescence microscopy to examine the role of cytoplasmic microtubules in these events.

METTL1‐Mediated M7G tRNA Modification Promotes Residual Liver Regeneration After Hepatectomy via Translational Control

Advanced Science, EarlyView.
METTL1 and its mediated m7G tRNA modification are significantly up‐regulated after partial hepatectomy (PHx). Overexpression of METTL1 improves the efficiency of liver regeneration after PHx, increases the proliferation of hepatocytes, and accelerates the recovery of liver function.

The coordination of nuclear envelope assembly and chromosome segregation in metazoans

Nucleus, 2020
The nuclear envelope (NE) is composed of two lipid bilayer membranes that enclose the eukaryotic genome. In interphase, the NE is perforated by thousands of nuclear pore complexes (NPCs), which allow transport in and out of the nucleus. During mitosis in

A Novel FGFR3‐Targeting Antibody‐Drug Conjugate Induces Tumor Cell Apoptosis through the cGAS–STING Pathway in Bladder Cancer

Advanced Science, EarlyView.
LZU‐WZLYCS01 is a novel FGFR3‐targeting ADC for bladder cancer with 7‐ethyl‐9‐fluorocamptothecin (A2) as its cytotoxic payload. LZU‐WZLYCS01 intracellularly releases A2, which targets MAD2L1 to activate the cGAS‐STING pathway and induce tumor cell apoptosis.
