Broer Group - Membrane transport and nutrition

Nutrients are essential for the growth and maintenance of cells and organisms. Membrane transporters are essential to deliver nutrients to cells and tissues and thus play a significant role in the regulation of metabolism. We study the role of amino acid transport in the onset of insulin resistance and the regulation of carbohydrate metabolism. Amino acid transport is crucial for growing cells and thus is a target to curtail cancer growth. We are investigating in how far amino acid transport in cancer cells is different from normal cells. In addition to amino acid transport we investigate the role of phospholipid transport in cell development and signalling in the immune system.

Highlights

Breaking the PhD mould: finding a career outside academia

Like many PhD students, Sarojini always imagined she would continue in research before she decided to pursue a career within the pharmaceutical industry. Sarojini’s passion for research flourished while studying at the ANU Research School of Biology.

How a rare disorder can lead to possible treatments for type 2 diabetes

Hartnup disorder is a rare disorder that is caused by an inability to absorb the breakdown products of protein digestion, namely amino acids. The disorder is named after the first reported case that showed symptoms similar to pellagra, a deficiency of the vitamin Niacin.

New treatments for T2 diabetes and cancer

If you think transporters are just for Star Trek fans, think again.  Professor Stefan Broer is using the transporters in cell membranes to develop new treatments for Type 2 diabetes and cancer.

The degree so good, you’ll never want it to end

Most students are happy to lay down their pens after submitting their honours thesis. But not Tze How Goh. The Bachelor of Science (Advanced) honours student has just finished his thesis, but is already back in the lab, continuing his research into treatments for diabetes.
