Species Dependent Toxicity Comparison Outcome

open access: yesAdvanced Science, Volume 13, Issue 34, 19 June 2026.
By quantitatively assessing and comparing toxicity responses across different animal species and material compositions, our data reveal that toxicity rankings among different materials may be reversed across species. ABSTRACT Toxicity comparison plays a crucial role in material selection across diverse application fields.

Centrosome and retroviruses: The dangerous liaisons

open access: yesRetrovirology, 2007
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.

Directed Evolution Improves the Catalytic Efficiency of APEX2‐Mediated Proximity‐Dependent RNA Labeling

open access: yesAdvanced Science, Volume 13, Issue 32, 9 June 2026.
ABSTRACT Engineered ascorbate peroxidase APEX2 has been widely used for spatially restricted profiling of subcellular biomolecules, but its catalytic efficiency toward newly developed probes such as biotin‐aniline (Btn‐An) remains suboptimal. To overcome this limitation, we performed yeast surface display‐based directed evolution to enhance APEX2 ...

A Cancer-Associated Missense Mutation in PP2A-Aα Increases Centrosome Clustering during Mitosis

open access: yesiScience, 2019
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.

T‐Cell Exhaustion in the Tumor Microenvironment: Subcellular Dysfunction, Pan‐Cancer Characteristics, and Therapeutic Interventions

open access: yesAdvanced Science, Volume 13, Issue 33, 15 June 2026.
This study elucidates the mechanisms of subcellular multidimensional collapse in exhausted T cells. By specifically targeting the nucleus, mitochondria, and endoplasmic reticulum, strategic interventions can effectively remodel the compromised organelle network. This integrated approach drives comprehensive T cell resuscitation, ultimately establishing

Wave Mechanics of Ciliary Proteins: Quantum‐Enabled Sensing and Energy Transfer in the “Cellular Antenna”

open access: yesAggregate, Volume 7, Issue 6, June 2026.
This review surveys eukaryotic cilia as putative quantum‐enabled sensory and regulatory centers. It highlights their multifaceted roles in the cell, focuses on the nontrivial roles of quantum mechanics in their membrane and cytoskeletal proteins, and introduces the essential building blocks enabling quantum properties to survive in the warm, wet, and ...

TTK Overexpression: A Negative Prognostic Biomarker in Anaplastic Thyroid Carcinoma

open access: yesCancer Medicine, Volume 15, Issue 6, June 2026.
ABSTRACT Background Given threonine and tyrosine kinase (TTK)'s oncogenic role in various cancers and its understudied status in thyroid cancer, this study investigates TTK expression in thyroid lesions to assess its diagnostic and therapeutic potential. Methods We analyzed differential TTK expression levels using public datasets (n = 143) and clinical

Epigenetic Aging in Brain Tissue of the Self‐Fertilizing Vertebrate, Kryptolebias marmoratus

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Using the self‐fertilizing vertebrate Kryptolebias marmoratus, we developed an epigenetic clock from brain tissue that predicts chronological age with high accuracy, demonstrating that DNA methylation changes consistently with age even in the near absence of genetic variation. The 40 age‐associated CpG sites identified map to genes with conserved roles

Cdk4 and nek2 signal binucleation and centrosome amplification in a her2+ breast cancer model.

open access: yesPLoS ONE, 2013
Centrosome amplification (CA) is a contributor to carcinogenesis, generating aneuploidy, and chromosome instability. Previous work shows that breast adenocarcinomas have a higher frequency of centrosome defects compared to normal breast tissues. Abnormal

Centrosome clustering and cyclin D1 gene amplification in double minutes are common events in chromosomal unstable bladder tumors

open access: yesBMC Cancer, 2010
Background Aneuploidy, centrosome abnormalities and gene amplification are hallmarks of chromosome instability (CIN) in cancer. Yet there are no studies of the in vivo behavior of these phenomena within the same bladder tumor. Methods Twenty-one paraffin-
