A Bright Ratiometric Dipyrene Probe for Functional Imaging of Condensate Microenvironments in Living Cells

Advanced Science, EarlyView.
Ratiometric dipyrene imaging resolves monomer (M) and excimer (E) channels and computes pixel‐wise E/M maps within biomolecular condensates, yielding physicochemical fingerprints shaped by coupled polarity‐related solvation and microviscosity. These spatial fingerprints enable quantitative phenotyping of cellular states, exemplified by separation of ...

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.

Phosphorylated ERK5/BMK1 transiently accumulates within division spindles in mouse oocytes and preimplantation embryos

Folia Histochemica et Cytobiologica, 2011
MAP kinases of the ERK family play important roles in oocyte maturation, fertilization, and early embryo development. The role of the signaling pathway involving ERK5 MAP kinase during meiotic and mitotic M-phase of the cell cycle is not well known. Here,

PFKFB4 Deubiquitination by USP10 Enhances Fumarate Metabolism to Orchestrate the KDM1A/Rad51 Axis and Confer Radioresistance in Lung Cancer

Advanced Science, EarlyView.
USP10 binds to and stabilizes PFKFB4, enhancing glycolytic ATP production, which activates the urea cycle and elevates fumarate. This inhibits histone demethylase KDM1A, leading to increased H3K4me1 enrichment at the Rad51 promoter and direct activation of Rad51 transcription, which confers lung cancer radioresistance. The PFKFB4 inhibitor 5MPN targets

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 ...

CALB2 is a Mechanoresistance Gene in Metastatic Prostate Cancer

Advanced Science, EarlyView.
Prostate cancer cell lines of differing origins were cultured over many passages while being subjected to semi‐lethal levels of fluid shear stress, representing the harsh mechanical environment these cells are subjected to in the circulation during the process of distant metastasis.

Kinesins regulate the heterogeneity in centrosome clustering after whole-genome duplication

Life Science Alliance
Kinesin levels determine mitotic spindle polarity after whole-genome duplication. After whole-genome duplication (WGD), tetraploid cells can undergo multipolar mitosis or pseudo-bipolar mitosis with clustered centrosomes.

High‐Throughput Mechanical Rupture of Nuclear Envelope and the Intracellular Dynamics of Massive Wound Repair

Advanced Science, EarlyView.
A microfluidic device with monolithically integrated nanostructures enables high‐throughput wounding of the cell membrane and nuclear envelope. The spatial distribution of charged multivesicular body protein 4B (CHMP4B) within the cell is mapped before and after wounding, showing involvement in repair of both the cell membrane and nuclear envelope ...

Histone H3K18 Lactylation Promotes the Malignant Progression of Wilms Tumor via a PSRC1/AKT/HIF‐1α Positive Feedback Loop

Advanced Science, EarlyView.
In nephroblastoma, aberrant glycolysis drives lactate accumulation, which elevates histone H3K18 lactylation via p300. Lactylation of the PSRC1 promoter activates its transcription. PSRC1 competitively binds AKT, relieving PTEN‐mediated inhibition and triggering AKT/mTOR/HIF‐1α signaling.
