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

open access: yesIntegrative 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

Multi-gene epigenetic silencing of tumor suppressor genes in T-cell lymphoma cells; delayed expression of the p16 protein upon reversal of the silencing

open access: yes, 2006
Udgivelsesdato: 2006-MarTo understand better T-cell lymphomagenesis, we examined promoter CpG methylation and mRNA expression of closely related genes encoding p16, p15, and p14 tumor suppressor genes in cultured malignant T-cells that were derived from ...

Targeting hexokinase 2 to induce breast cancer cell senescence

open access: yesBritish 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 ...

A Three‐Dimensional Culture–Drug Sensitivity Test Predicts MDM2 Inhibitor–Sensitivity in SMARCB1/INI1‐Deficient Tumors

open access: yesCancer Science, EarlyView.
This study aimed to determine whether personalized selection of effective drugs for SMARCB1/INI1‐deficient tumors is feasible using in vitro drug sensitivity profiling. Drug sensitivity was assessed using a short‐term collagen gel–embedded three‐dimensional drug sensitivity test (3D‐DST) in tumors derived from SMARCB1/INI1‐deficient tumor cell line ...

Correlation between Methylation and Expression Level of P15 and P16 Genes during Differentiation of Cord Blood Stem Cells into Erythroid Lineage Mediated by Erythropoietin

open access: yesNovelty in Biomedicine, 2015
Background: Several influential factors such as transcription factors and intracellular signaling components are involved in differentiation of stem cells into a specific lineage. P15 and p16 proteins are among these factors.

Hepatocyte Growth Hormone Receptor Ablation Is Associated With Aging Phenotypes and Hepatic Mitochondrial Dysfunction. [PDF]

open access: yesAging Cell
Hepatocyte‐specific GHR ablation is associated with hepatic and age‐related pathologies, triggering adipose‐liver crosstalk via elevated circulating GH and subsequent CD36‐dependent hepatic steatosis. This loss impairs STAT5b phosphorylation and enhances PPARγ nuclear activation, upregulating Pdk4 and Cd36 to drive mitochondrial dysfunction and ectopic

CRB1‐Associated Inherited Retinal Dystrophies: Prospective Natural History Study With 4 Years of Follow‐Up

open access: yesClinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background The lack of validated and sensitive clinical endpoints remains a major challenge in the design of gene therapy trials for inherited retinal dystrophies (IRDs). This prospective longitudinal cohort study describes the natural disease progression of IRDs caused by pathogenic mutations in the Crumbs homologue 1 (CRB1) gene, and ...

Suppression of Retinal Neovascularisation by Tetrahedral Framework Nucleic Acids‐Resveratrol Via Dual Anti‐Angiogenesis and Anti‐Inflammation

open access: yesCell Proliferation, EarlyView.
Resveratrol‐loaded tetrahedral framework nucleic acids (tFNAs‐RSV) enable concurrent anti‐angiogenic and anti‐inflammatory therapy, enhancing ocular delivery and bioactivity. In hypoxia‐induced retinal neovascularisation, tFNAs‐RSV reduce neovascular lesions, vascular leakage and inflammatory infiltration by suppressing HIF‐1, p38 MAPK and NF‐κB p65 ...
