Structural and drug discovery studies of oxidative stress regulator, thioredoxin-interacting protein

Funded Activity Summary

Toxic oxygen molecules known as Reactive Oxygen Species (ROS) are by-product of normal metabolism. The excess of ROS is damaging and is well known to contribute to ageing process and age-related diseases such as cancer, diabetic complications, immune-system decline, and cardiovascular conditions to name a few. The human body possesses several defense systems that protect us from the excess of ROS maintaining a healthy level of ROS. A down-regulator of one of this systems, a protein called TXNIP, has been recently discovered. The amount of TXNIP is increased in such conditions as high glucose, a first sign of diabetes, and under ischemia, a shortage of blood supply occurring during heart attack. This weakens the anti-oxidant defense systems and makes the organism more vulnerable to ROS exposure. Our team of researchers embarked on structural and functional studies of TXNIP with the purpose to identify small molecules that can interfere with the undesirable action of TXNIP. These molecules might become useful therapeutic agents to counteract weakening organism's ROS defense system caused by TXNIP in many disease conditions such as, cancer, diabetes and cardiac failure.
