Amphibian‐Derived Peptide OA‐AL14 Alleviates UVB‐Induced Skin Photoaging via Autophagy Activation Mediated by the AMPK/mTOR Pathway

Integrative Zoology, EarlyView.
The schematic diagram illustrates that the amphibian‐derived peptide OA‐AL14 protects against UVB‐induced skin photoaging through a dual mechanism: activating the Nrf2 pathway to counteract oxidative stress and modulating the AMPK/mTOR axis to induce protective autophagy. ABSTRACT Skin photoaging, primarily driven by ultraviolet B (UVB) radiation, is a

Mesenchymal Stem Cells From a Klinefelter Syndrome Patient: Functional Characterization and Therapeutic Implications

Andrology, EarlyView.
ABSTRACT Background Cell therapy, particularly those utilizing mesenchymal stem/stromal cells (MSCs), is gaining traction as a therapeutic option for regenerative treatment in patients with limited therapeutic options. Although the safety of MSC‐based interventions is well established, uncertainties remain regarding how genetic abnormalities and ...

Brain metastasis‐associated fibroblasts shape the tumour microenvironment to enhance cancer cell invasion

Brain Pathology, EarlyView.
Brain metastasis‐associated fibroblasts are active stromal components of the metastatic niche characterised by extracellular matrix remodelling and production of pro‐migratory mediators. They promote monocyte and cancer cell migration and enhance cancer cell invasion while having no growth‐promoting effect on cancer cells.

Targeting hexokinase 2 to induce breast cancer cell senescence

British Journal of Pharmacology, EarlyView.
Background and Purpose Hexokinase 2 (HK2) is a key enzyme linked to high tumour cell proliferation. Its inhibitors such as 3‐bromopyruvic acid (3‐BP) induce cancer cell death, highlighting HK2 modulation as potential anti‐cancer treatment. However, standard chemotherapies often cause the emergence of senescent cancer cells, which goes along with cell ...

The c‐Src inhibitor eCF506 diminishes opioid tolerance and reduces β‐arrestin2 recruitment

British Journal of Pharmacology, EarlyView.
Morphine activation of μ receptors causes tolerance through c‐Src activation and β‐arrestin2 recruitment. c‐Src inhibition or degradation reduces β‐arrestin2 recruitment, μ receptor endocytosis, while causing receptor upregulation, all likely contributing to reduced morphine tolerance.

The DNA/RNA Helicase SETX Maintains R‐Loop Homeostasis to Promote Chemoresistance in Ovarian Cancer

Cancer Science, EarlyView.
SETX maintains R‐loop homeostasis by resolving excessive R‐loops, thereby promoting tumor initiation and chemoresistance. Deficiency of SETX leads to accumulation of unsolved pathological R‐loops, resulting in irreparable DNA damage and ultimately leading to tumor suppression and chemosensitivity.

The E‐cadherin‐Wnt‐mir‐994 Axis Repurposes a Cadherin Switch for Niche Robustness and Germline Stem Cell Maintenance

Cell Proliferation, EarlyView.
In the Drosophila ovarian niche, an E‐cadherin‐to‐N‐cadherin switch, mediated by Wnt‐mir‐994 signalling, is repurposed to ensure niche resilience. This compensatory mechanism maintains niche integrity and stem cell support upon E‐cadherin loss, revealing a robustness circuit.
