I am currently researching the potential mutagenicity of consumer products, and specifically sunscreens and moisturizers. Building on the research done by a previous MARC student who conducted Ames Tests on specific sunscreens, I am now testing the chemicals found to be "common denominators" in all of the products found to have mutations in the Ames Test even at the highest dilution.
To read what I am currently doing or have done in the past please read my blog!
Below is my past research on the carcinogenicity of e-cigarette fluids.
There are many products that contain chemicals that are unregulated or untested that people use every day.
The resurgence of nicotine popularity on the social and public health scene has left many scientists, researchers, and government officials feeling completely unaware of how this phenomenon will impact the next generation. As this is a relatively recent crisis, there has yet to be comprehensive studies conducted on the long-term impacts of e-cigarette usage.
According to a study conducted by British American Tobacco Company researchers, the e-cigarette vapor was found to be non-mutagenic using the Ames test, (1) supporting claims that e-cigarettes are “safer” than traditional cigarettes. (2) As a mutagenicity study on nicotine products conducted by a tobacco company presents a conflict of interest, and I was unable to find similar studies, I was intrigued to research the mutagenicity of e-cigarettes, specifically a popular e-cigarette brand: Juul.
Juul pod fluids have been found to have up to three times the amount of nicotine per milliliter as other e-cigarette brands, and one pod is equivalent to 20 cigarettes worth of nicotine.(3) The FDA has indicated that e-cigarettes contain “detectable levels of known carcinogens and toxic chemicals to which users could be exposed,” (4) but this is a topic that has not been fully explored in the scientific and clinical world. (5)
I have conducted an Ames test on Juul pod fluid in order to determine its mutagenicity. The Ames Test or Salmonella typhimurium reverse mutation assay is a mutagenicity test which identifies carcinogens, substances and exposures that can lead to cancer, by using mutagenicity in bacteria, which is high correlation model for mutagenicity in animals. (6)
I think that this project is compelling because it is so relevant to our generation and the tobacco industry’s re-emergence on the social and public health scene. I think that this crisis and resurgence of nicotine and tobacco popularity has left many scientists, researchers, and government officials feeling blindsided.
Many of the components in this research topic are controversial as well as cutting edge. I believe that we as researchers are entering uncharted waters in some ways and in others reliving the past.
I hope that the health impacts and implications will be made clear by through studies and research so that the next generation will be well informed and make healthy decisions.
My next steps in my experiment will be reproducing my results in another two Ames Tests and then taking my research into human cell culture in semester two of senior year.
I hope to continue to conduct research throughout my life as a student and later in life. Effective and Compelling Scientific Communication can be very powerful, and I hope that as I continue my research career that I will be able to communicate the impact and relevance of the work that I am doing to both people in and out of the scientific sphere.
I hope that my research has inspired others to ask questions and take initiative to seek the answers. I am very excited to expand upon my research findings and explore new topics.
