Tetraploidy-associated centrosome overduplication in mouse early embryos
Recently, we observed that tetraploidization of certain types of human cancer cells resulted in upregulation of centrosome duplication cycles and chronic generation of the extra centrosome. Here, we investigated whether tetraploidy-linked upregulation of

An interstitium‐mimicking membrane combines three‐dimensional alveolar geometry, high pore interconnectivity, and mechanical compliance to overcome transport limitations of conventional lung‐on‐chip barriers. The resulting platform supports physiologic aerosol transport, quantitative analysis of cross‐barrier particle movement, and reveals divergent ...

A Cancer-Associated Missense Mutation in PP2A-Aα Increases Centrosome Clustering during Mitosis
Summary: Whole-genome doubling (WGD) is common early in tumorigenesis. WGD doubles ploidy and centrosome number. In the ensuing mitoses, excess centrosomes form a multipolar spindle, resulting in a lethal multipolar cell division.

SIRT Family: Biological Functions and Therapeutic Targets
SIRT1–SIRT7 networks from transgenic mice to human‑relevant therapeutic targets. SIRT1–SIRT7 form an isoform‑, organ‑, and disease‑specific regulatory network. Transgenic Sirt1–7 mouse models define central regulatory SIRTs (SIRT1, SIRT3, SIRT6), context‑dependent modifiers (SIRT2, SIRT4, SIRT5, SIRT7), and their key mechanisms and target organs. These

Centrosome and retroviruses: The dangerous liaisons
Centrosomes are the major microtubule organizing structures in vertebrate cells. They localize in close proximity to the nucleus for the duration of interphase and play major roles in numerous cell functions.

YPEL3 functions as a tumor suppressor in HNSCC by inhibiting tumor progression and promoting apoptosis. Mechanistically, it enhances epithelial–immune crosstalk through the CREB1‐mediated CXCL16–CXCR6 axis, facilitating CD8+ T‐cell infiltration and highlighting its potential as a prognostic biomarker and immunotherapy target.

The identification of a patient carrying a novel homozygous p.(Gln206Ter) POC5 variant revealed a metabolic phenotype associated with POC5 deficiency. POC5 deficiency disrupts centriolar architecture and ciliary organization, leading to impaired proliferation, premature cellular senescence, and reduced insulin signaling.

The centrosome and cell proliferation
Centrosomes are frequently amplified in cancer cells. Increased numbers of centrosomes can give rise to multipolar spindles in mitosis, and thereby lead to the formation of aneuploid daughter cells. However, whether centrosome amplification is a cause or
