Engineering Lipid Nanoparticles for Precision RNA Delivery: Design Principles, Targeting Strategies, and Clinical Prospects

Cancer Nexus, EarlyView.
ABSTRACT Lipid nanoparticles (LNPs) represent the most clinically advanced platform for RNA delivery and have enabled major breakthroughs in vaccines and gene therapies. However, their broader application is still limited by inefficient extrahepatic delivery, immunogenicity, and insufficient control over tissue‐ and cell‐specific targeting. This review

Genotoxicity assessment in estuarine environments using oyster hemocytes: a comparative comet assay study

Ocean and Coastal Research
The comet assay with sentinel organisms has been employed to determine the genotoxicity of water samples for environmental risk or hazard assessment. Methodologies with diverse sensitivities have been proposed to elucidate the sources of genetic damage,

Genomic instability in patients with type 2 diabetes mellitus on hemodialysis

Revista Brasileira de Hematologia e Hemoterapia, 2012
OBJECTIVE: A previous study by our research group evaluated the levels of DNA damage using the comet assay in hemodialysis patients with type 2 diabetes mellitus. The same blood samples were also evaluated using the cytochalasin B micronucleus assay.

ID3 deficiency alters chromatin accessibility at DSB sites and enhances vulnerability to HDAC inhibition

International Journal of Cancer, EarlyView.
What's New? Errors in DNA double‐strand break (DSB) repair can lead to mutations, chromosomal instability, and ultimately cancer. Inhibitor of DNA‐binding 3 (ID3), a transcriptional repressor, is crucial to promoting DSB repair and helping maintain genome stability. Here, the authors investigated ID3 regulation of DNA repair via chromatin accessibility

DNA damage in buccal cells in oral PMDs and malignant disorders by comet assay

Brazilian Journal of Oral Sciences, 2019
Aim: DNA damage associated with Oral Squamous Cell Carcinoma (OSCC) and potentially malignant disorders (PMDs) is produced due to carcinogenic agents or increased oxidative stress. Comet assay can assist in early detection and evaluation of the amount of

Alkaline comet assay v1

, 2020
Stilbenes are a group of chemicals characterized with the presence of 1,2-diphenylethylene. Previously, our group has demonstrated that synthesized (E)-N-(2-(3, 5-dimethoxystyryl) phenyl) furan-2-carboxamide (BK3C231) possesses potential chemopreventive activity specifically inducing NAD(P)H:quinone oxidoreductase 1 (NQO1) protein expression and ...
