If the clot barrier is removed, excessive oxygen presence in the media may enhance this toxic

+
-
production because of high metabolic rate of the cells. These toxic products, also known as reactive

+
-
oxygen species (ROS), may increase the cell damage further. Thus, it is needed to regard the big

+
-
 
+
-
constructing a sensitive and robust device. Hypoxia inducible promoters and their regulator proteins

-
 
+

are responsible for this critical mission. Beside of this, we also want to prevent the damage caused

by reperfusion of blood to the hypoxic environment, we also need an additional sensitive receptor

systems. These two receptors will hopefully regulate the release of clot dissolving factors synthesized

by our engineered vessel cells. Moreover, we hope to maximize the reduction of ROS damage to the

cells by producing antioxidant enzymes to degrade ROS within the cells. By re-providing vital oxygen

Project Abstract

Tissue hypoxia, or ischemia, is the condition that describes the poor conveyance of oxygen and other vital products to body tissues and organs which consequently results tissue death. Up to now, the number one cause of death worldwide is caused by ischemia and related conditions such as heart attack or stroke. It is needed to regard the big picture of the condition in order to solve the problem. In our project, our will is to build two different devices, which work synergistically, to fix these two distinct situations. We decided to use ‘’hypoxia inducible systems” and ‘’reactive oxygen species (ROS) sensitive gene fragments’’. These two receptors will hopefully regulate the release of clot dissolving factors and antioxidant peptides synthesized by our engineered vessel cells. We hope to bring encouraging results in vitro to pave the way of this promising system into the lifesaving remedy method.
