- First, I began to look into the possible production of the alkaloid isorhy, as was brought to my attention by Nina and Si
- It is rumoured to be a potential treatment for Parkinson's and it would make a good project if this were to be produced by bacteria
- On further research it turns out that the evidence for this drug as a treatment is weak and there is no information available about the gene or genes that encode it, so the idea was dropped
- After being inspired by a student from the Royal College of Arts who presented us with her work on a project to create a living dress, I began to research the notion of a melanin tattoo, so that alpha-melanin stimulating hormone is applied to the skin and held in place until the skin darkens in the shape of the template. The alpha-MSH could be produced by bacteria.
- the alpha-MSH gene is produced as one gene that also contains beta-MSH and gamma-MSH that are made available through post-transcriptional processing, so only the alpha-MSH region is required as it is the best characterised and has been expressed before
- Once the alpha-MSH is expressed, it can be collected, soaked into silk (for example) that is cut into a pattern and will allow the hormone to diffuse into the skin, producing a (probably temporary) tattoo.
