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.

TGFbeta Isoforms Differentially Regulate Fibrosis And Inflammation In Diabetic Nephropathy Via KLF Transcription Factors

Summary
Progressive scarring and inflammation in the kidney represent the final common injury pathway for diseases that lead to kidney failure, including diabetic nephropathy. This project explores the interplay between the molecular processes that are triggered by high glucose levels in patients with diabetic nephropathy, some of which are deleterious and some potentially 'protective'. By understanding these mechanisms we will be able to prevent and more effectively treat kidney disease in diabetes.
HB-EGF Promotes Recovery From Experimental Acute Renal Failure

Summary
Kidney failure is a frequent complication of serious injury or illness. Although the kidneys generally recover, this can take some time. Before they recover, the inability of the kidneys to function normally adds significantly to the suffering and debility of these sick people. The question we wish to ask is how do the kidneys repair themselves? Ultimately, we would like to know how we could speed up this process. It seems that the kidney remodels after injury by increasing production of growth ....Kidney failure is a frequent complication of serious injury or illness. Although the kidneys generally recover, this can take some time. Before they recover, the inability of the kidneys to function normally adds significantly to the suffering and debility of these sick people. The question we wish to ask is how do the kidneys repair themselves? Ultimately, we would like to know how we could speed up this process. It seems that the kidney remodels after injury by increasing production of growth factors, which are specialised proteins that tell the kidney cells what to do. If we could determine which of these was the most important then it might be possible to give it to patients. If we could even find out how these growth facotrs work, then it might be possible to replace them with a drug that could be more easily administered than a protein.Read moreRead less
Altered Intracellular Signalling In Response To Hyperglycaemia Reflects An Inherent Predisposition To Nephropathy

Summary
Diabetic nephropathy affects 30-50% of patients with diabetes mellitus. The reasons as to why only a proportion of patients develop this devastating complication is not clear. Poor control of blood sugar levels has been well characterised as being of aetiological importance in its genesis, but is clearly not the sole factor responsible. Genetic factors appear to predispose individuals to developing diabetic nephropathy, with a significantly higher number of affected patients having a family hist ....Diabetic nephropathy affects 30-50% of patients with diabetes mellitus. The reasons as to why only a proportion of patients develop this devastating complication is not clear. Poor control of blood sugar levels has been well characterised as being of aetiological importance in its genesis, but is clearly not the sole factor responsible. Genetic factors appear to predispose individuals to developing diabetic nephropathy, with a significantly higher number of affected patients having a family history of hypertension and vascular disease. Our own preliminary studies using cells from human kidneys have demonstrated that there are clearly 2 responses observed with respect to alterations in intracellular signalling after exposure to high glucose concentrations and hormones known to be of importance in the development of diabetic nephropathy (such as angiotensin II and insulin-like growth factor-1). These responses appear to be specific to the patient from which the kidney tissue is derived. Thus the aim of the present study is to determine prospectively, whether the groups differ with regards their intracellular signalling and subsequent development of tubulointerstitial pathology in an in vitro model of diabetes mellitus.Read moreRead less
