Multi-Marker Immunofluorescent Staining And Pd-L1 Detection On Circulating Tumour Cells From Ovarian Cancer Patients, Du-Bois Asante, Michael Morici, Ganendra R. K. A. Mohan, Emmanuel Acheampong, Isaac Spencer, Weitao Lin, Paula Van Miert, Samantha Gibson, Aaron B. Beasley, Melanie Ziman, Leslie Calapre, Tarek M. Meniawy, Elin S. Gray

Research outputs 2014 to 2021

Detection of ovarian cancer (OC) circulating tumour cells (CTCs) is primarily based on targeting epithelial markers, thus failing to detect mesenchymal tumour cells. More importantly, the immune checkpoint inhibitor marker PD-L1 has not been demonstrated on CTCs from OC patients. An antibody staining protocol was developed and tested using SKOV-3 and OVCA432 OC cell lines. We targeted epithelial (cytokeratin (CK) and EpCAM), mesenchymal (vimentin), and OC-specific (PAX8) markers for detection of CTCs, and CD45/16 and CD31 were used for the exclusion of white blood and vascular endothelial cells, respectively. PD-L1 was used for CTC characterisation. CTCs were enriched using the …

Pereira, Bob Mirzai, Leslie Calapre, Wendy N. Erber, Melanie R. Ziman, Elin S. Gray

Research outputs 2014 to 2021

Background:

The stratification of uveal melanoma (UM) patients into prognostic groups is critical for patient management and for directing patients towards clinical trials. Current classification is based on clinicopathological and molecular features of the tumour. Analysis of circulating tumour cells (CTCs) has been proposed as a tool to avoid invasive biopsy of the primary tumour. However, the clinical utility of such liquid biopsy depends on the detection rate of CTCs.

Methods:

The expression of melanoma, melanocyte, and stem cell markers was tested in a primary tissue microarray (TMA) and UM cell lines. Markers found to be highly expressed in primary …

Review Of Sexual Health Issues Linked With Cardiovascular Disease And Type 2 Diabetes Mellitus In Aboriginal And Torres Strait Islander Males, Veronica Collins, Tamara J. Swann, Jane Burns, Tim Moss, Mick Adams

Australian Indigenous HealthBulletin

There are well established links between male sexual health conditions and chronic disease, particularly cardiovascular disease (CVD) and type 2 diabetes (T2DM). Erectile dysfunction (ED) and low testosterone are two sexual health conditions that are relatively common among the wider male population. However, there is a lack of data specifically about these sexual problems among Aboriginal and Torres Strait Islander males.

One of the most important findings of research regarding the links between sexual health and chronic disease is that ED can be a risk marker for future CVD or undiagnosed T2DM. Understanding these links can lead to more holistic …

Hyaluronic Acid In Viscous Malignant Mesothelioma Pleural Effusion, Hui Min Cheah, Deirdre Fitzgerald, Amber Louw, Jenette Creaney, Y. C.Gary Lee

Research outputs 2014 to 2021

© 2020 The Authors. Respirology Case Reports published by John Wiley & Sons Australia, Ltd on behalf of The Asian Pacific Society of Respirology Malignant pleural effusion (MPE) is common with mesothelioma. We report two cases of extraordinarily viscous MPEs associated with mesothelioma. The viscosity prohibited spontaneous gravity-dependent drainage via indwelling pleural catheters. Our ex vivo experiments found very high hyaluronic acid (HA) content within the fluid. Treatment of the fluid with hyaluronidase, but not with deoxyribonucleases, significantly reduced fluid viscosity. The results provide proof that HA can contribute to high viscosity of pleural fluid in mesothelioma. Research into strategies …

Comparison Of Circulating Tumour Dna And Extracellular Vesicle Dna By Low-Pass Whole-Genome Sequencing Reveals Molecular Drivers Of Disease In A Breast Cancer Patient, Olivia Ruhen, Bob Mirzai, Michael E. Clark, Bella Nguyen, Carlos Salomon, Wendy Erber, Katie Meehan

Research outputs 2014 to 2021

© 2020 by the authors. Licensee MDPI, Basel, Switzerland. There is increasing recognition of circulating tumour DNA (ctDNA) as a non-invasive alternative to tumour tissue for the molecular characterisation and monitoring of disease. Recent evidence suggests that cancer-associated changes can also be detected in the DNA contained within extracellular vesicles (EVs). As yet, there has been limited investigation into the relationship between EV DNA and ctDNA, and no studies have examined the EV DNA of breast cancer patients. The aim of this study was to use low-pass whole-genome sequencing to identify copy number variants (CNVs) in serial samples of both …

Pleural Fluid Investigations For Pleural Infections, Bapti Roy, Hui Juin Shak, Y. C.Gary Lee

Research outputs 2014 to 2021

Over 1.5 million patients are admitted to hospital with pneumonia in the United States each year. Up to 50% of them can develop a parapneumonic effusion which is associated with higher mortality. The incidence of pleural infection continues to rise, particularly in the elderly and those with comorbidities. Parapneumonic effusions cover a spectrum of presentations from a free-flowing 'simple parapneumonic effusion' to a septated 'complicated parapneumonic effusion' (CPE) (usually from bacterial pleural invasion) and 'empyema' (presence of pleural pus). Pleural infection is defined as either CPE or empyema, and usually requires evacuation of the infected fluid. Laboratory investigations play an …

Hair And Salivary Cortisol And Their Relationship With Lifestyle, Mood And Cognitive Outcomes In Premanifest Huntington’S Disease, Travis Cruickshank, Tenielle Porter, Simon M. Laws, Mel Ziman, Danielle M. Bartlett

Research outputs 2014 to 2021

Salivary cortisol dysrhythmias have been reported in some, but not all studies assessing hypothalamic–pituitary–adrenal (HPA) axis function in Huntington’s disease (HD). These differences are presumed to be due to environmental influences on temporal salivary cortisol measurement. Further exploration of HPA-axis function using a more stable and longer-term measure, such as hair cortisol, is needed to confirm earlier findings. This study aimed to evaluate hair and salivary cortisol concentrations and their associations with clinical and lifestyle outcomes in individuals with premanifest HD (n = 26) compared to healthy controls (n = 14). Participants provided saliva and hair samples and data were …

Research outputs 2014 to 2021

Adipogenesis associated Mth938 domain containing (AAMDC) represents an uncharacterized oncogene amplified in aggressive estrogen receptor-positive breast cancers. We uncover that AAMDC regulates the expression of several metabolic enzymes involved in the one-carbon folate and methionine cycles, and lipid metabolism. We show that AAMDC controls PI3K-AKT-mTOR signaling, regulating the translation of ATF4 and MYC and modulating the transcriptional activity of AAMDC-dependent promoters. High AAMDC expression is associated with sensitization to dactolisib and everolimus, and these PI3K-mTOR inhibitors exhibit synergistic interactions with anti-estrogens in IntClust2 models. Ectopic AAMDC expression is sufficient to activate AKT signaling, resulting in estrogen-independent tumor growth. Thus, AAMDC-overexpressing …

Introduction: Amidst the evolving COVID-19 pandemic, understanding the transmission dynamics of the SARS-CoV-2 virus is key to providing peace of mind for the community and informing policy-making decisions. While available data suggest that school-aged children are not significant spreaders of SARS-CoV-2, the possibility of transmission in schools remains an ongoing concern, especially among an aging teaching workforce. Even in low-prevalence settings, communities must balance the potential risk of transmission with the need for students' ongoing education. Through the roll out of high-throughput school-based SARS-CoV-2 testing, enhanced follow-up for individuals exposed to COVID-19 and wellbeing surveys, this study investigates the dynamics …

Research outputs 2014 to 2021

Type 1 diabetes mellitus (T1DM) is a chronic autoimmune disease caused by the specific destruction of pancreatic islet β cells and is characterized as the absolute insufficiency of insulin secretion. Current insulin replacement therapy supplies insulin in a non-physiological way and is associated with devastating complications. Experimental islet transplantation therapy has been proven to restore glucose homeostasis in people with severe T1DM. However, it is restricted by many factors such as severe shortage of donor sources, progressive loss of donor cells, high cost, etc. As pluripotent stem cells have the potential to give rise to all cells including islet β …

Using Exercise And Nutrition To Alter Fat And Lean Mass In Men With Prostate Cancer Receiving Androgen Deprivation Therapy: A Narrative Review, Rebekah L. Wilson, Dennis R. Taaffe, Robert U. Newton, Nicolas H. Hart, Philippa Lyons-Wall, Daniel A. Galvao

Research outputs 2014 to 2021

Fat mass (FM) gain and lean mass (LM) loss are common side effects for patients with prostate cancer receiving androgen deprivation therapy (ADT). Excess FM has been associated with an increased risk of developing obesity-related comorbidities, exacerbating prostate cancer progression, and all-cause and cancer-specific mortality. LM is the predominant contributor to resting metabolic rate, with any loss impacting long-term weight management as well as physical function. Therefore, reducing FM and preserving LM may improve patient-reported outcomes, risk of disease progression, and ameliorate comorbidity development. In ADT-treated patients, exercise and nutrition programs can lead to improvements in quality of life and …
