Four students who recently won the top awards in the biological division of the UCF Graduate Research Symposium went on to compete at the statewide competition, where one brought home a second-place finish.<\/p>\n
Simeon Thibeaux, who is investigating the links between an enzyme and fatty liver diseases, was runner-up in his division\u2019s competition at the University of South Florida.<\/p>\n
The biomedical students\u2019 cutting-edge research spanned from looking at ways to reduce bad cholesterol to curbing the spread of Lyme disease. The winners earned high praise from 80 faculty judges who reviewed more than 200 projects during the UCF competition.<\/p>\n
Here\u2019s a snapshot of their work and how they placed at the UCF competition.<\/p>\n
Simeon Thibeaux, Biotechnology<\/strong> Simeon Thibeaux has spent the past two years researching an enzyme in the liver that contributes to fatty liver disease. His research found that the enzyme cathepsin B controls bad cholesterol secretion by the liver, thus reducing risk of the disease. Fatty liver disease can lead to hepatocellular carcinoma, a form of liver cancer.<\/p>\n \u201cHepatocellular carcinoma is very difficult to treat, and in most cases can only be corrected with a liver transplant,\u201d Thibeaux said, noting that patients have a less than a 5 percent survival rate after five years of diagnosis. \u201cSo my goal is to identify potential mechanisms that you can target and treat before you get to the point where it\u2019s no longer clinically treatable.\u201d<\/p>\n Thibeaux said he has spent countless hours working on this research.<\/p>\n \u201cBeyond everything that you see on my poster, there is a lot that goes on behind the scenes to make sure you are doing everything right,\u201d he said. \u201cSo it\u2019s nice to know that all the late nights and early mornings pay off.\u201d<\/p>\n \u201cSimeon is without a question one of the brightest young scientists I have ever encountered who has always exceeded my expectations,\u201d mentor Shadab Siddiqi said. \u201cI am not at all surprised by his win.\u201d<\/p>\n Thibeaux is heading to medical school after graduating this spring.<\/p>\n Philip Adams, Biomedical Sciences<\/strong> Adams has spent the past five years working with Jewett researching Lyme disease \u2013 a tick-borne illness afflicting more than 300,000 people a year.<\/p>\n From his research, Adams has identified a new gene (bb0562) in borrelia burgdorferi<\/em>, the bacteria that allows the tick to spread the infection.<\/p>\n \u201cWe found that when we remove this gene from the bacteria, the bacteria are no longer able to infect the animals, which shows this gene is really important for causing Lyme disease,\u201d Adams said. \u201cLearning more about the basic biology of the organism can help us find new therapeutics and diagnostic tools.\u201d<\/p>\n His research on the survival mechanism for Lyme disease has been published in Nucleic Acids Research<\/em>, an international peer-reviewed journal published by Oxford University Press. In 2014, he was also invited to train in RNA biochemistry techniques at the Max F. Perutz Laboratories in Vienna.<\/p>\n \u201cPhilip has matured over the past five years in incredible ways,\u201d Jewett said. \u201cHe has been very successful and has become an expert in molecular biology, gene regulation, pathogenesis. I am very proud of him, and winning this award is the perfect culmination to the end of his career as a graduate student here.\u201d<\/p>\n After graduating from UCF this summer, Adams will complete a post-doctoral fellowship at the National Institutes of Health.<\/p>\n Carolina Rodrigues Felix, Biomedical Sciences<\/strong> According to the Centers for Disease Control, tuberculosis caused 1.8 million deaths worldwide in 2015. Rodrigues Felix is trying to reduce deaths by finding a new drug to treat this disease that affects one-third of the world\u2019s population. Her research investigates whether marine-derived compounds in sponges can kill dormant or tolerant bacteria,that cause tuberculosis.<\/p>\n \u201cThe bacteria that causes tuberculosis are very difficult to kill because they can sometimes become tolerant to the drugs that are currently available,\u201d Rodrigues Felix said. \u201cThe treatment we have now takes about six months with four antibiotics administered. So our goal is to find new molecules that can more effectively kill the bacteria and shorten the treatment time.\u201d<\/p>\n This is Rodrigues Felix\u2019s second win at the Graduate Research Forum, having received the top prize in 2015 for her research on TB.<\/p>\n \u201cCarolina is setting a strong foundation for discovering new TB drugs and for others to be able to learn what we have learned,\u201d said Rohde. \u201cIt\u2019s always a proud moment to see a student get recognized for their hard work and achievements and it was well deserved.\u201d<\/p>\n
