Effects of Acetone on the CrdRS Pathway of H. pylori

Hey everyone!

My name is Yusheng Qin. I’m a rising Junior and a Biology major at the College of William and Mary. For the past year, I’ve been working in Dr. Mark Forsyth’s lab on signal transduction in Helicobacter pylori. H. pylori (HP) is a bacterium that causes many gastric diseases in humans such as gastric ulcers and gastric cancers. In order to thrive in the highly acidic environment in the stomach, HP has evolved complex mechanisms for resistance to environmental changes in the stomach such as pH fluctuations.¬†One way the gastric pathogen achieve this is through the use of two-component signal transduction (TCST) systems. This summer I will be studying one of these TCST systems named CrdRS.
