I am a reproductive physiologist investigating the nature and actions of hormones, particularly steroids and transforming growth factor-? superfamily members, regulating follicle growth and oocyte quality in the ovary, implantation and breakthrough bleedi
Prof A Suhrbier is the Group Leader of the Inflammation Biology Group at the Queensland Institute of Medical Research. The group focuses at the applied end of inflammation research and development and will be involved in the identification and development of new interventions and diagnostics for inflammatory diseases and cancer, often in collaboration with the biotech industry.
Linking Estrogens, Prostatitis And Prostate Cancer

Summary
Prostatitis is very common and a significant health issue that affects men from their 20's. Estrogens promote inflammation and inflammation is associated with the development of cancer. If this study links estrogens, prostatitis and prostate cancer, we can provide better treatment for prostatitis, thus preventing progression to prostate cancer
Steroid hormones, such as oestrogen and cortisol, act in the body by binding a family of proteins (nuclear receptors) that bind directly to the DNA to regulate genes. The mechanisms underlying this process are complex and involve recruitment of additional molecules or coactivators to improve efficiency. Recently a novel coactivator was identified termed SRA, which remarkably is never made into protein in cells, rather exerting its effects as a RNA. We have identified a novel family of proteins t ....Steroid hormones, such as oestrogen and cortisol, act in the body by binding a family of proteins (nuclear receptors) that bind directly to the DNA to regulate genes. The mechanisms underlying this process are complex and involve recruitment of additional molecules or coactivators to improve efficiency. Recently a novel coactivator was identified termed SRA, which remarkably is never made into protein in cells, rather exerting its effects as a RNA. We have identified a novel family of proteins that bind to SRA in cancer cells, and may well play a critical role in regulating how SRA modulates genes. This project seeks to understand how this family interacts with SRA, the functional effects on breast cancer cells, and the detailed 3-dimensional structure of the family members coupled with SRA. This work will provide novel insight into how SRA regulates steroid hormone action, and may create new potential avenues for developing therapeutics in breast cancer.Read moreRead less
Combating Giardiasis By Investigating New Potent Compound Series As Leads For Improved Treatment Options

Summary
Giardia parasites infect ~1 billion people globally and are responsible for significant morbidity and disadvantage. There is no licensed vaccine and current treatment options are inadequate, resulting in poor compliance, treatment failures, rapid re-infection and drug resistance. New therapies are needed to combat this parasite and improve the health of millions world-wide. We will address this issue by investigating new drug candidates for the treatment of Giardia infections.
Discovery Of Active Metabolic Pathways Suitable For Drug Targeting In Trypanosoma Brucei

Funding Amount
$485,517.00
Summary
Sleeping Sickness is a parasitic disease affecting many of the world’s poorest countries, and is fatal if left untreated. The aim of this project is to identify new metabolic pathways in the parasite that causes Sleeping Sickness, and to investigate how drugs interfere with parasite metabolism. This will provide the basis for new drug discovery efforts and facilitate the development of new medicines for Sleeping Sickness.
Function And Physiological Role Of Inhibitory Circuits In The Amygdala

Funding Amount
$741,518.00
Summary
The amygdala is part of the brain that assigns emotional content to our sensory world and dysfunction of the amygdala is responsible for many anxiety-related disorders. Many anxiolytics, like valium, act on receptors in the amygdala. In this project we will study circuits in the amygdala that are modulated by anxiolytics. These studies will provide essential information in the understanding of anxiety disorders and help in developing drugs to treat these disorders.
