The road less taken: Dihydroflavonol 4‐reductase inactivation and delphinidin anthocyanin loss underpins a natural intraspecific flower colour variation

open access: yesMolecular Ecology, EarlyView.
Abstract Visual cues are of critical importance for the attraction of animal pollinators, however, little is known about the molecular mechanisms underpinning intraspecific floral colour variation. Here, we combined comparative spectral analysis, targeted metabolite profiling, multi‐tissue transcriptomics, differential gene expression, sequence ...

Precision design of stable genetic circuits carried in highly‐insulated E. coli genomic landing pads

open access: yesMolecular Systems Biology, 2020
Genetic circuits have many applications, from guiding living therapeutics to ordering process in a bioreactor, but to be useful they have to be genetically stable and not hinder the host. Encoding circuits in the genome reduces burden, but this decreases

Evidence for a Role of Extraintestinal Pathogenic Escherichia coli, Enterococcus faecalis and Streptococcus gallolyticus in the Aetiology of Exudative Cloacitis in the Critically Endangered Kākāpō (Strigops habroptilus)

open access: yesMolecular Ecology, EarlyView.
ABSTRACT The kākāpō is a critically endangered flightless parrot which suffers from exudative cloacitis, a debilitating disease resulting in inflammation of the vent margin or cloaca. Despite this disease emerging over 20 years ago, the cause of exudative cloacitis remains elusive.

HIV Dynamics and Integrase Inhibitors

open access: yesAntiviral Chemistry and Chemotherapy, 2009
The integrase inhibitor (INI) raltegravir has shown promising results in clinical trials to date, reducing second phase HIV RNA levels by 70% in comparison with standard regimens. These trial results have been limited by the 50 copies/ml detection limit of the HIV RNA assay and have not investigated the effect of an INI regimen on levels of latently ...

Weight gain, obesity, and the impact of lifestyle factors among people living with HIV: A systematic review

open access: yesObesity Reviews, EarlyView.
Summary HIV remains a significant health concern, but the advent of antiretroviral therapy (ART) has transformed it into a manageable chronic condition. However, weight gain and obesity pose a substantial challenge for people living with HIV (PLWH). Moreover, the role of lifestyle has not yet been comprehensively investigated.

Nucleosome DNA unwrapping does not affect prototype foamy virus integration efficiency or site selection.

open access: yesPLoS ONE, 2019
Eukaryotic DNA binding proteins must access genomic DNA that is packaged into chromatin in vivo. During a productive infection, retroviral integrases (IN) must similarly interact with chromatin to integrate the viral cDNA genome. Here we examine the role

Integrase-RNA interactions underscore the critical role of integrase in HIV-1 virion morphogenesis

open access: yeseLife, 2019
ABSTRACTA large number of HIV-1 integrase (IN) alterations, referred to as class II substitutions, exhibit pleotropic effects during virus replication. However, the underlying mechanism for the class II phenotype is not known. Here we demonstrate that all tested class II IN substitutions compromised IN-RNA binding in virions by one of three distinct ...

Analysis of carbohydrates and glycoconjugates by matrix‐assisted laser desorption/ionization mass spectrometry: An update for 2021–2022

open access: yesMass Spectrometry Reviews, Volume 44, Issue 3, Page 213-453, May/June 2025.
Abstract The use of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this review is the 12th update of the original article published in 1999 and brings coverage of the literature to the end of 2022.
