Welcome to the Stanford team Wiki for iGEM 2010
Stanford iGEM is a student-run, faculty-directed research group at Stanford University. The objective of our interdisciplinary group is to design and build novel engineered biological systems using standardized DNA-based parts to submit to the iGEM (International Genetically Engineered Machines) competition, held annually at MIT. Our research draws from the principles of synthetic biology, an emerging interdisciplinary and multidisciplinary area that involves the design and construction of biological systems. Here is our 2010 team profile.

Our Project: EscheRatio Coli!
Our project this year is to add a new tool to the synthetic biologist's toolkit: a system to allow E. coli to sense the ratio of two different chemicals in its environment and produce a protein output based on that ratio.
We are implementing two different ratio sensor designs:
- an sRNA-based sensor that reports the relationship between the present ratio of the chemicals and a single desired ratio via the presence or absence of signal
- a kinase-phosphatase sensor that reports the exact ratio via the intensity of the signal
Applications
Cancer
Ratios of growth factor to receptors can indicate the malignancy of tumors and predict when they are likely to metastasize. Our sensor could be used as either a research tool to discover more important ratios or as a method of targeting in-vivo drug delivery to those cells with tumor-like expression patterns.
Preterm Labor
Preterm labor is a leading cause of infant mortality, even in the US. Our sensor could detect hormone or bacterial imbalance and alert the expectant mother or her doctor that she is likely to enter preterm labor, allowing a pre-emptive response that could save her child's life.
Metabolic Flux
Bacterial manufacturing has huge economic potential, but is often limited by the efficiency of biological pathways. Our sensor could be used to regulate enzyme production, inhibiting enzyme output in the absence of substrate and increasing output once substrate becomes abundant.
