Baicalein Sensitizes Radioresistant BT549 and MCF7‐R Breast Cancer Cells by Modulating Rac1 Signaling

Phytotherapy Research, EarlyView.
ABSTRACT Radioresistance remains a key barrier in breast cancer (BC) treatment. Baicalein, a flavonoid from Scutellaria baicalensis, has shown potential to enhance radiosensitivity. This study investigates its efficacy and mechanism in radioresistant BC models. Radioresistant BC cell models were established via fractionated irradiation and validated by

Increased DNA damage in full-grown oocytes is correlated with diminished autophagy activation

Nature Communications
Unlike mild DNA damage exposure, DNA damage repair (DDR) is reported to be ineffective in full-grown mammalian oocytes exposed to moderate or severe DNA damage. The underlying mechanisms of this weakened DDR are unknown.

Biomaterial‐Integrated Electroporation for Therapeutic Delivery: From Gene Editing to Tumor Ablation and Immune Modulation

Small, EarlyView.
Biomaterial‐integrated electroporation establishes a programmable therapeutic interface that coordinates electric‐field modulation, transient or irreversible membrane permeabilization, cargo stabilization, and immune remodeling. This Review highlights how nanocarriers, hydrogels, and bioelectronic interfaces expand electroporation from conventional ...

DNA damage accumulates and responses are engaged in human ALS brain and spinal motor neurons and DNA repair is activatable in iPSC-derived motor neurons with SOD1 mutations

Acta Neuropathologica Communications, 2020
DNA damage is implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS). However, relationships between DNA damage accumulation, DNA damage response (DDR), and upper and lower motor neuron vulnerability in human ALS are unclear; furthermore ...

Staging concept for aging management: Definition, mechanism, and coping strategies

VIEW, EarlyView.
We divided the overall aging stage into “pre‐aging”, “aging compensation”, and “aging disability”. For each stage, we delineate the clinical presentations, biological phenomena, theoretical underpinnings, and key management priorities. Abstract Aging, as a gradual and largely irreversible biological process, characterized by declining organismal ...

Management of Advanced Prostate Cancer in the Asia‐Pacific Region: Summary of the Asia‐Pacific Advanced Prostate Cancer Symposium 2025

Asia-Pacific Journal of Clinical Oncology, EarlyView.
Summary of the Asia Pacific Advanced Prostate Cancer Symposium 2025, showing disciplines and diversity of participants, discussion topics (high‐risk localized/locally advanced prostate cancer; PSA persistence and recurrence; radioligand therapy; genetics and genomics; bone protection and other aspects of supportive care), key themes, and high‐level ...

HIV-1 Vpr-induced DNA damage activates NF-κB through ATM-NEMO independent of cell cycle arrest

mBio
Lentiviruses encode a number of multi-functional accessory proteins, however, the primary role of the accessory protein Vpr remains unclear. As Vpr engages the host DNA damage response (DDR) at multiple steps, modulation of the DDR is considered central ...

TONSL Promotes Hepatocellular Carcinoma Progression by Inhibiting Apoptosis Through Homologous Recombination Repair

Cancer Science, EarlyView.
In hepatocellular carcinoma, the 8q24.3 locus is frequently amplified and is associated with tumor‐specific overexpression of TONSL. TONSL promotes homologous recombination repair through RAD51, limits γH2AX accumulation and apoptosis, supports tumor growth, and its loss increases sensitivity to poly (ADP‐ribose) polymerase (PARP) inhibition.

Bystander communication and cell cycle decisions after DNA damage

Frontiers in Genetics, 2015
The DNA Damage Response (DDR) has two main goals, to repair the damaged DNA and to communicate the presence of damaged DNA. This communication allows the adaptation of cellular behavior to minimize the risk associated with DNA damage. In particular, cell
