Bone‐Derived dECM Hydrogels Support Tunable Microenvironments for In Vitro Osteogenic Differentiation

open access: yesAdvanced Healthcare Materials, EarlyView.
A tunable methacrylated decellularized bone matrix hydrogel (dECM‐MA) is developed to support 3D culture of human osteoblasts. The hydrogel preserves bone‐specific ECM cues and allows precise control over mechanical properties. This system provides a customizable platform for studying osteogenic differentiation and modeling bone tissue environments for

Vibration‐Mediated Recovery of Irradiated Osteocytes and Their Regulatory Role in Breast Cancer Bone Metastasis

open access: yesAdvanced Healthcare Materials, EarlyView.
Radiotherapy damages bone and disrupts osteocyte function, yet mechanically mediated protection remains largely unexplored. This study demonstrates that low‐magnitude, high‐frequency (LMHF) vibration mitigates irradiated osteocyte apoptosis, restores their ability to regulate breast cancer extravasation, and acts synergistically with radiotherapy to ...

Impact of Nanoparticle Stiffness on Endosomal Escape and Signaling Pathways in Cytosolic Delivery

open access: yesAdvanced Healthcare Materials, EarlyView.
Nanoparticle (NP) stiffness affects cellular uptake, but its impact on intracellular distribution remains unclear. This study synthesizes silica nanocapsules with varying stiffness, inspired by viral mechanisms, and applies assays to measure cellular uptake and escape efficiency.

Structural basis for a Polθ helicase small-molecule inhibitor revealed by cryo-EM

open access: yesNature Communications
DNA polymerase theta (Polθ) is a DNA helicase-polymerase protein that facilitates DNA repair and is synthetic lethal with homology-directed repair (HDR) factors. Thus, Polθ is a promising precision oncology drug-target in HDR-deficient cancers.

A Human Kidney Tubuloid Model of Repeated Cisplatin‐Induced Cellular Senescence and Fibrosis for Drug Screening

open access: yesAdvanced Healthcare Materials, EarlyView.
Replicating aging and senescence‐related pathophysiological responses in kidney organoids remains a significant challenge. Human adult renal tubular organoid, tubuloids, are successfully developed recapitulating cellular senescence that is the central pathophysiological mechanism of chronic kidney disease (CKD).

ROS‐Scavenging Multifunctional Microneedle Patch Facilitating Wound Healing

open access: yesAdvanced Healthcare Materials, EarlyView.
A reactive oxygen species (ROS) scavenging and immunomodulatory microneedle patch based on hyaluronic acid methacrylate (HaMA) and Flightless I (Flii)‐siRNA‐laden arginine functionalized poly (β‐amino ester)/alginate particles is developed for chronic wound healing applications.

H2AX promotes replication fork degradation and chemosensitivity in BRCA-deficient tumours

open access: yesNature Communications
Histone H2AX plays a key role in DNA damage signalling in the surrounding regions of DNA double-strand breaks (DSBs). In response to DNA damage, H2AX becomes phosphorylated on serine residue 139 (known as γH2AX), resulting in the recruitment of the DNA ...
