Mechanoadaptation via Myosin Cytoplasmic Redistribution Protects Circulating Tumor Cells From Shear‐induced Death During Hematogenous Dissemination

open access: yesAdvanced Science, Volume 13, Issue 33, 15 June 2026.
This study investigates how CTCs survive varying shear stress during hematogenous metastasis. We uncover a self‐protection mechanism, by which non‐adherent CTCs adapt to high shearing milieu through accumulated cytoplasmic myosin‐mediated disruption of myosin‐actin binding, attenuating force transmission into chromatin to protect CTCs from shear ...

VSMC phenotypic switching in thoracic aortic aneurysm at single‐cell resolution: Trajectories, regulatory circuits, and spatial niches

open access: yesClinical and Translational Discovery, Volume 6, Issue 3, June 2026.
•Single‐cell/spatial multi‐omics identify four VSMC phenotypic states in TAA progression. •KLF4 as master hub (TGF‐β/TNF‐α/mechanical stress) orchestrating chromatin remodelling. •Pseudotime trajectories mapping contractile phenotypes towards osteogenic (RUNX2/SOX9) and inflammatory (TNF‐α/IL‐6) fates within spatial medial niches. •cfDNA biomarkers and

Transient expression of myosin tail XI-2, but not the expression of any of the other tested myosin tails, affects virus replication.

open access: yes, 2014
A-F, Fluorescence intensity (arbitrary units) of the TMV-GFP infection sites analyzed in Figure 1. Fluorescence intensity was quantified using ImageJ software and normalized to the area of the same infection sites. Except for myosin XI-2 tails (Figure 3D)

Inhibition of myosin XI-2 disrupts the normal subcellular localization of expressed 126k:GFP.

open access: yes, 2014
A, co-expression of 126k:GFP together with RFP. The 126k:GFP accumulates in large aggregates. B, co-expression of 126k:GFP together with myosin XI-2 tails. 126k:GFP is dispersed into numerous small aggregates.

Pathways of Protein Secretion in Prokaryotes and Eukaryotes: Molecular Mechanisms, Biological Functions, and Therapeutic Opportunities

open access: yesMedComm, Volume 7, Issue 6, June 2026.
This graphical abstract delineates noncanonical protein secretion systems across eukaryotes and prokaryotes. Eukaryotic UcPS covers four ER–Golgi bypass pathways, enabling rapid leaderless protein export via direct transmembrane translocation or vesicle‐mediated release.

Breaking the Heat Tolerance Response: The Crucial Role of MFAP4 in Combating Heat‐Induced Cardiac Injury

open access: yesThe FASEB Journal, Volume 40, Issue 10, 31 May 2026.
MFAP4 deficiency exacerbates heatstroke outcomes, accelerating hyperthermia, delaying recovery, reducing survival, and worsening cardiac injury. Conversely, MFAP4 overexpression enhances cellular thermoresistance. MFAP4 orchestrates transcriptional reprogramming in response to HS.

Expression, Splicing, and Evolution of the Myosin Gene Family in Plants     [PDF]

open access: yes, 2011
Plants possess two myosin classes, VIII and XI. The myosins XI are implicated in organelle transport, filamentous actin organization, and cell and plant growth.

Sensing and Filtering Environmental Fluctuations: The Case of Biomolecular Condensates in Plants

open access: yesAdvanced Science, Volume 13, Issue 27, 13 May 2026.
The diversity of plant condensates reflects constraints of sessile organisms to coordinate postembryonic development with environmental adaptation. This review examines how plants employ condensates to integrate temperature, light, redox, and nutrient signals.
