In this work, we examined the regulation by GTP and UTP of the UMP kinases from eight bacterial species. The enzyme from Gram-positive organisms exhibited cooperative kinetics with ATP as substrate. GTP decreased this cooperativity and increased the affinity for ATP. UTP had the opposite effect, as it decreased the enzyme affinity for ATP. The nucleotide(More)
The tyrosine kinase Lyn is involved in oncogenic signalling in several leukaemias and solid tumours, and we have previously identified a pathway centred on Cbp [Csk (C-terminal Src kinase)-binding protein] that mediates both enzymatic inactivation, as well as proteasomal degradation of Lyn via phosphorylation-dependent recruitment of Csk (responsible for(More)
OBJECTIVE To develop a peer-review model for assessment and quality improvement of cancer multidisciplinary teams (MDTs) and qualitatively assess its feasibility and acceptability in Australia. DESIGN, SETTING AND PARTICIPANTS A peer-review methodology was developed, based on the United Kingdom's National Health Service peer-review model and a(More)
Utilisation of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and guide sheath (EBUS-GS) for diagnosis and staging of lung cancer is gaining popularity, however, its impact on clinical practice is unclear. This study aimed to determine the impact of the introduction of endobronchial ultrasound-guided procedures (EBUS) on time(More)
We identified in Salmonella enterica serovar Typhi a cluster of four genes encoding a deoxyribokinase (DeoK), a putative permease (DeoP), a repressor (DeoQ), and an open reading frame encoding a 337 amino acid residues protein of unknown function. We show that the latter protein, called DeoM, is a hexamer whose synthesis is increased by a factor over 5(More)
Lyn is involved in erythropoietin (Epo)-receptor signaling and erythroid homeostasis. Downstream pathways influenced following Lyn activation and their significance to erythropoiesis remain unclear. To address this, we assessed a gain-of-function Lyn mutation (Lyn(up/up)) on erythropoiesis and Epo receptor signaling. Adult Lyn(up/up) mice were anemic, with(More)
Erythropoiesis is controlled principally through erythropoietin (Epo) receptor signaling, which involves Janus kinase 2 (JAK2) and Lyn tyrosine kinase, both of which are important for regulating red blood cell (RBC) development. Negative regulation of Lyn involves C-Src kinase (Csk)-mediated phosphorylation of its C-terminal tyrosine, which is facilitated(More)
In this study, linked Western Australian health data were used to determine presence of an antibiotic-resistant infection (ABRI) for all people diagnosed with a primary invasive cancer in 2009. Of 10 858 cancer cases, 154 (1.42%) had an ABRI. Patients with an ABRI were older (71.5 vs 66 years), and more had died in the year following diagnosis (37.7 vs(More)
Erythroid homoeostasis is primarily controlled by Epo (erythropoietin) receptor signalling; however, the Lyn tyrosine kinase plays an important subsidiary role in regulating the erythroid compartment. Nonetheless, specific erythroid pathways that require Lyn activity and their biological significance remain unclear. To address this, we asked what(More)
BACKGROUND There is no mechanism in place for monitoring or quality improvement of cancer multidisciplinary meetings (MDM) in Australia. AIM To develop a peer-review process for quality improvement of MDM. METHODS This project involved three phases: (i) development of a draft peer-review framework, supporting documents and peer-review process; (ii)(More)
