Chromosome segregation in a minimal bacterial cell driven by SMC protein complexes
Abstract Minimal bacterial cells such as JCVI‐Syn3A provide a powerful system for uncovering the essential mechanisms of chromosome organization and segregation. Lacking canonical systems such as Min and ParABS, JCVI‐Syn3A relies primarily on structural maintenance of chromosomes (SMC) protein complexes for partitioning.

Resilient Biophysical Phenotype of Memory CD4 + T Cells in Long‐Lived Mice
Aging is associated with increased stiffness and reduced migratory capacity of memory CD4+ T cells; however, these biophysical declines do not persist in exceptionally long‐lived mice. Instead, long‐lived individuals preserve T cell mechanics, migration and intracellular architecture, supporting mechanical resilience as a hallmark of successful immune ...

Development of the HTRF assay to evaluate the auxin‐induced binding between TIR1 and IAA7
Summary Auxin plays diverse roles in plant growth and development, including sensing environmental changes. Quantifying the interaction between auxin coreceptors provides the molecular basis for cells to sense and adapt to environmental cues. Although several assays are available, a more high‐throughput method is necessary to efficiently evaluate the ...

Cell surface interactome analysis identifies TSPAN4 as a negative regulator of PD‐L1 in melanoma
Using cell surface proximity biotinylation, we identified tetraspanin TSPAN4 within the PD‐L1 interactome of melanoma cells. TSPAN4 negatively regulates PD‐L1 expression and lateral mobility by limiting its interaction with CMTM6 and promoting PD‐L1 degradation.

Emerging strategies to target metastasis and therapy resistance in melanoma
Emerging studies propose new approaches to interfere with melanoma progression. In recognition of melanoma awareness month, at Molecular Oncology, we highlight recently published research articles, focusing on novel therapeutic targets driving metastatic spread and outlining different strategies to overcome resistance to BRAF inhibitors and anti‐PD‐1 ...

Chronic Hypoxia Disrupts Spermatogenesis Through ASXL2–EZH2–Mediated Microtubule Destabilization
This study reveals the mechanism by which chronic hypoxia impairs spermatogenesis via the ASXL2–EZH2 axis, hindering the transition of spermatids from round to elongated forms. Key findings reveal that under hypoxic conditions, downregulated ASXL2 expression reduces EZH2 binding to the CEP162 promoter, leading to decreased H3K27me3 modification and ...

Castration‐resistant prostate cancer (CRPC) remains sensitive to ferroptosis, but its intrinsic resistance is poorly understood. Here, we identify NFIB as a master suppressor. SIRT7‐mediated NFIB acetylation drives its liquid–liquid phase separation, which promotes SLC3A2 transcription to inhibit ferroptosis.
