Universal and Lineage‐Specific Patterns in the Distribution of ECOD Domain Homology Groups Across Superkingdoms

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Proteins are built from modular domains that serve as fundamental units of structure and evolution. While individual domains have been extensively cataloged, their collective distribution across the lineages of life has remained poorly resolved.

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]

, 2001
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

Deciphering diverse cell‐death patterns to predict the prognosis and potential therapy target of hepatocellular carcinoma patients

VIEW, EarlyView.
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.

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

Journal 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 ...

Delivery of nano‐formulated drugs to solid tumours is selectively increased by co‐application of the vascular disrupting agent CA4P

British Journal of Pharmacology, EarlyView.
Background and purpose Nano‐formulated chemotherapeutics prolong systemic availability of drugs and can reduce systemic toxicity, but their accumulation in solid tumours is often limited and unpredictable. Broadly applicable strategies to selectively enhance tumour delivery are lacking.

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

Nature 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 ...

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

Marine 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.

Development and analytical validation of a targeted short‐read next generation sequencing‐based pharmacogenetic panel for comprehensive variant detection

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Genomic profiling of patients for genetic variants that modify the effect of specific medications has many benefits, including the possibility of avoiding toxicities and ensuring an adequate effect of the medication. Our intention was to develop a comprehensive, high‐quality pharmacogenetic test panel for clinical use ...

Proteostasis of organelles in aging and disease

The FEBS Journal, EarlyView.
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

Discovery of New DNA Topoisomerase II Inhibitors using Structure Based Virtual Screening Method

Journal of the Turkish Chemical Society, Section A: Chemistry, 2019
DNA topoisomerases are proved therapeutic targets of anticancer and antibacterial drugs. Structures of topoisomerase–DNA and inhibitor ternary complexes have revealed the exact binding sites and mechanisms of topoisomerase poisons. There are two isoforms
