The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

The Role Of Cyp2e1, Alcohol And HCV In Modulation Of Hepatocyte Homeostasis HCV Replication And Resistance To Interferon

Summary
Liver disease caused by alcohol consumption and hepatitis C virus (HCV) infection are major national health problems. Liver disease caused by HCV is greatly accelerated by alcohol consumption, however, the connection between the biochemical events initiated by alcohol, HCV and inflammatory pathways resulting in liver disease are not well understood. Preliminary studies have identified a link between an important alcohol-metabolising enzyme, Cyp2e1, HCV replication, oxidative stress and a powerfu ....Liver disease caused by alcohol consumption and hepatitis C virus (HCV) infection are major national health problems. Liver disease caused by HCV is greatly accelerated by alcohol consumption, however, the connection between the biochemical events initiated by alcohol, HCV and inflammatory pathways resulting in liver disease are not well understood. Preliminary studies have identified a link between an important alcohol-metabolising enzyme, Cyp2e1, HCV replication, oxidative stress and a powerful mediator of liver injury called tumour necrosis factor alpha. Furthermore we have shown that alcohol metabolism by Cyp2e1 results in an increase in HCV replication and negatively impacts on the anti-viral action of interferon. The studies contained within this proposal aim to build on these exciting new insights by attempting to identify new mediators and mechanisms of liver disease as a consequence of Cyp2e1 expression, alcohol and HCV replication. We will also examine the molecular mechanisms by which alcohol potentiates HCV replication. These studies will assist in developing therapeutic strategies that will benefit alcohol- and HCV-related liver disease.Read moreRead less
Characterization Of ARL6IP5 In Hepatitis C-related Liver Cancer

Summary
The incidence and mortality from liver cancer is increasing rapidly in Australia, and hepatitis C virus infection is the most common cause. How hepatitis C leads to liver cancer is largely unknown. We identified a novel gene termed ARL6IP5 that appears to be specifically increased in liver tissue by chronic hepatitis C infection. In this project we will characterize the involvement and role of this gene in liver cancer development. Knowledge gained from this study will help us understand how hep ....The incidence and mortality from liver cancer is increasing rapidly in Australia, and hepatitis C virus infection is the most common cause.

A Study Of The Relationship Between Vitamin D Status And The Severity And Outcomes Of Chronic Non-cholestatic Liver Disease

Funding Amount
$133,351.00
Summary
Vitamin D deficiency is associated with common and severe conditions such as cancer, cardiovascular disease, autoimmune disease and diabetes. Recent studies suggest that vitamin D deficiency also worsens the severity and prognosis of chronic liver disease and that vitamin D replacement may improve outcomes. This research will further investigate the relationship of vitamin D deficiency to liver disease caused by the common conditions hepatitis B and C and non-alcoholic fatty liver disease and th ....Vitamin D deficiency is associated with common and severe conditions such as cancer, cardiovascular disease, autoimmune disease and diabetes.
