NQO1‐Responsive Prodrug for in Cellulo Release of Cytochalasin B as Cancer Cell‐Targeted Migrastatic
The design, synthesis, biochemical, and cell biological evaluation of the NQO1‐targeted prodrug BQTML‐CB is reported. BQTML‐CB selectively releases cytochalasin B upon activation by the quinone‐oxidoreductase NQO1 associated with invasiveness of cancer cells, representing a novel approach to improve cancer selectivity and reduce immunosuppressive ...

Trapping of the transport-segment DNA by the ATPase domains of a type II topoisomerase
Type II topoisomerases alter DNA topology to control DNA supercoiling and chromosome segregation and are targets of clinically important anti-infective and anticancer therapeutics.

DNA Topoisomerase 1α Promotes Transcriptional Silencing of Transposable Elements through DNA Methylation and Histone Lysine 9 Dimethylation in Arabidopsis [PDF]
RNA-directed DNA methylation (RdDM) and histone H3K9 dimethylation (H3K9me2) are related transcriptional silencing mechanisms that target transposable elements (TEs) and repeats to maintain genome stability in plants.

Biomimetic nanocarriers based on liposomes and Myxobacteria outer‐membrane vesicles (OMVs) are effective antibiotic delivery systems. Hybrids have a higher drug loading and can target intracellular pathogens, while OMVs evade immune clearance. Biomimetic nanoantibiotics effectively eliminate the biofilms of Gram‐negative bacteria. Besides, Myxobacteria

The role of NF-Y in the transcriptional regulation of human topoisomerase II¯ : a thesis presented to Massey University in partial fulfilment of the requirement for the degree of Master of Science in Biochemistry [PDF]
DNA topoisomerases are ubiquitous enzymes that catalyse reactions that alter the topological state of DNA during the various processes of DNA metabolism including transcription, recombination, replication and chromosome segregation. Human cells exhibit a

How topoisomerase IV can efficiently unknot and decatenate negatively supercoiled DNA molecules without causing their torsional relaxation. [PDF]
Freshly replicated DNA molecules initially form multiply interlinked right-handed catenanes. In bacteria, these catenated molecules become supercoiled by DNA gyrase before they undergo a complete decatenation by topoisomerase IV (Topo IV).

Cardenolide‐functionalized extracellular vesicles enable targeted delivery of the chemotherapeutic doxorubicin to A549 lung cancer cells by binding Na+/K+‐ATPase, which is overexpressed in these cells. Surface‐modified, drug‐loaded EVs exhibit enhanced cytotoxicity compared to unmodified EVs and free drug, suggesting this system may lower the effective

Abstract Ninety percent of all primary liver malignancies are hepatocellular carcinomas (HCC), making liver cancer the third most common cause of cancer‐associated mortality. Different patterns of programmed cell death (PCD) are crucial for the survival of tumors, and they might serve as a prognostic marker for HCC.
