Bioorthogonal Photoactivation of 2‐Nitrobenzyl Caged Doxorubicin Anticancer Prodrugs on Gold Nanostars

Advanced Materials, EarlyView.
Bioorthogonal chemistry was applied to intracellularly photoactivate Doxorubicin (Dox) using gold nanostars (AuNSt) and near‐infrared (NIR) light. Two prodrugs were used: one photoactivatable, masked with 2‐nitrobenzyl carbamate (proDox1) and another photolabile, masked with 2‐nitrobenzyl diol (proDox2), which was attached to the AuNSt surface.

DNA damage by lipid peroxidation products: implications in cancer, inflammation and autoimmunity

AIMS Genetics, 2017
Oxidative stress and lipid peroxidation (LPO) induced by inflammation, excess metal storage and excess caloric intake cause generalized DNA damage, producing genotoxic and mutagenic effects.

Circular RNA PTPN4 Contributes to Blood‐Brain Barrier Disruption during Early Epileptogenesis

Advanced Science, EarlyView.
Epileptic condition induces CircPTPN4 upregulation, which promotes ECE‐1 expression through competitive sequestration of miR‐145a‐5p. The elevated ECE‐1 catalyzes the ET‐1 production, leading to p38/MAPK pathway activation and subsequent downregulation of tight junction protein expression. This cascade results in increased BBB permeability and enhanced

DNA adducts, mutations and cancer [PDF]

Carcinogenesis, 1993
Anyone having lectured on DNA adducts is likely to be familiar with the first question after the presentation: 'What is the relationship of DNA adducts and cancer?'. Although there are a number of reviews on the topic (1-5), my personal response, instead of going into lengthy circumstantial argumentation and hand-waving, has been a quotation from ...

A Unique Chimeric RNA: ERCC1‐iASPP Drives Benzo[a]pyrene‐Induced Lung Carcinogenesis via Dual Coding and Non‐Coding Mechanisms

Advanced Science, EarlyView.
The chimeric RNA ERCC1‐iASPP possesses dual coding and non‐coding functions, synergistically accelerating the process of cellular malignant transformation. Abstract Genetic variation at 19q13.3 critically modulates chemical carcinogen‐induced lung carcinogenesis, particularly in mediating the activity of benzo[a]pyrene (B[a]P), a major polycyclic ...

Biomarker-based evaluation of aflatoxin B1 exposure in cattle [PDF]

Veterinary World
Background and Aim: Assessment of aflatoxin B1 (AFB1) exposure in cattle traditionally relies on feed analysis, which may not reflect chronic exposure or accurately indicate individual susceptibility.

Interaction between adverse pregnancy history and polycyclic aromatic hydrocarbon-DNA adducts on missed abortion

环境与职业医学, 2022
BackgroundThe incidence rate of missed abortion is increasing year by year, but the etiology has not been fully elucidated. Adverse pregnancy history and exposure to polycyclic aromatic hydrocarbons (PAHs) may increase the risk of missed abortion ...

TRIM56 Aggravates Cerebral Ischemia‐Reperfusion Injury via Inhibiting KLF4‐Activated Ferroptosis Signaling

Advanced Science, EarlyView.
This study reveals that the E3 ubiquitin ligase TRIM56 exacerbates neuronal ferroptosis and brain damage by mediating K48‐linked ubiquitination and degradation of KLF4, leading to suppression of the xCT/GSH/GPX4 axis. Targeting TRIM56 alleviates cerebral ischemia‐reperfusion injury in vivo and in vitro, highlighting its therapeutic potential.

Mitochondrial stress in advanced fibrosis and cirrhosis associated with chronic hepatitis B, chronic hepatitis C, or nonalcoholic steatohepatitis

Hepatology, EarlyView., 2022
Adaptive mitochondrial mechanisms allow mitochondrial resilience and prevent the worsening of fibrosis, while deregulation of these mechanisms promotes the progression from no/minimal‐mild (F0‐F2) fibrosis to advanced fibrosis and cirrhosis (F3‐F4). Abstract Background and Aims Hepatitis B virus (HBV) infection causes oxidative stress (OS) and alters ...

DNA adducts of chemical carcinogens [PDF]

Carcinogenesis, 1995
Introduction During the 30 years or so following the identification of the first pure chemical carcinogen (1), no common factors or pathways in the mechanism of action of carcinogens from different chemical classes were evident. For this reason perhaps, each class of carcinogen, e.g.
