ChitoSilkBioPatch: A bio‐inspired wound dressing scaffold for antibiotic‐free diabetic wound management

open access: yesVIEW, EarlyView.
We present ChitoSilkBioPatch, a maleimide‐functionalized chitosan/dACM hydrogel integrated with a stretchable nanopatterned silk mesh to provide intrinsic, antibiotic‐free antibacterial activity and bioactive wound support. The scaffold eliminates S. aureus and P.

Distinct expression patterns for type II topoisomerases IIA and IIB in the early foetal human telencephalon

open access: yesJournal of Anatomy, 2015
TOP2A and TOP2B are type II topoisomerase enzymes that have important but distinct roles in DNA replication and RNA transcription. Recently, TOP2B has been implicated in the transcription of long genes in particular that play crucial roles in neural ...

Integrated multi‐omics analysis reveals metabolic reprogramming as a key driver of angiotensin II‐induced vascular remodeling

open access: yesVIEW, EarlyView.
This study investigates the molecular alterations underlying angiotensin II (Ang II)‐induced vascular remodeling in cardiovascular diseases using a multi‐omics approach. Through data exploration and integrated multi‐omics analysis, our findings reveal that Ang II‐driven vascular injury in vascular smooth muscle cells is mediated by metabolic ...

3-O-Methylfunicone, a Selective Inhibitor of Mammalian Y-Family DNA Polymerases from an Australian Sea Salt Fungal Strain

open access: yesMarine Drugs, 2009
We isolated a pol inhibitor from the cultured mycelia extract of a fungal strain isolated from natural salt from a sea salt pan in Australia, which was identified as 3-O-methylfunicone by spectroscopic analyses.

Antibacterial activity of a DNA topoisomerase I inhibitor versus fluoroquinolones in Streptococcus pneumoniae.

open access: yesPLoS ONE, 2020
The DNA topoisomerase complement of Streptococcus pneumoniae is constituted by two type II enzymes (topoisomerase IV and gyrase), and a single type I enzyme (topoisomerase I).

Double strand DNA cleavage by type II DNA topoisomerase from Drosophila melanogaster.

open access: yesJournal of Biological Chemistry, 1983
The purified type II DNA topoisomerase from the embryos of Drosophila melanogaster exists in its native form as a dimer of 170,000-dalton polypeptides. In addition to the 170,000-dalton polypeptides, 3 polypeptides with molecular weights of 151,000, 141,000, and 132,000 were resolved when the enzyme was analyzed by electrophoresis under denaturing ...

Trastuzumab Deruxtecan for HER2‐Low Metastatic Breast Cancer: Practical Considerations for Medical Oncologists and Pathologists in Australia

open access: yesAsia-Pacific Journal of Clinical Oncology, EarlyView.
ABSTRACT Trastuzumab deruxtecan (T‐DXd) is a third‐generation, HER2‐targeting antibody‐drug conjugate that has been shown to significantly prolong overall survival, compared with standard chemotherapy, when used to treat patients who have “HER2‐low” (HER2 immunohistochemistry [IHC] score 1+; or HER2 IHC 2+ plus in situ hybridization‐negative ...

Structural and functional insights into the T-even type bacteriophage topoisomerase II

open access: yesNature Communications
T-even type bacteriophages are virulent phages commonly used as model organisms, playing a crucial role in understanding various biological processes. One such process involves the regulation of DNA topology during phage replication upon host infection ...

The Rabl configuration limits topological entanglement of chromosomes in budding yeast. [PDF]

open access: yes, 2019
The three dimensional organization of genomes remains mostly unknown due to their high degree of condensation. Biophysical studies predict that condensation promotes the topological entanglement of chromatin fibers and the inhibition of function.

Hypomethylating agents in vacuoles, E1 enzyme, X‐linked, autoinflammatory, somatic syndrome (VEXAS): A systematic review

open access: yesBritish Journal of Haematology, EarlyView.
Summary VEXAS syndrome (vacuoles, E1 enzyme, X‐linked, autoinflammatory, somatic) is an X‐linked, systemic, haemato‐inflammatory syndrome caused by somatic mutations in the UBA1 gene. No standardized treatment guidelines exist, but evidence is emerging that treatment with hypomethylating agents (HMAs) can induce improvement of the inflammatory symptoms,
