Food Science & Technology students on the 2018 College Bowl team

Congratulations to the Food Science students on the College Bowl team on winning first place in the South Central Region competition on April 13, 2018. Their next competition will be competing next at Nationals Chicago!

Since 1985, the IFTSA College Bowl Competition has tested the knowledge of student teams from across the United States in the areas of food science and technology, history of foods and food processing, food law, and general IFT/food-related trivia.

The College Bowl is designed to facilitate interaction among students from different universities, stimulate the students’ desire to accumulate and retain knowledge, and provide a forum for students to engage in friendly competition. Teams for IFT Student Chapters in eight geographical areas of the Student Association compete in area competitions prior to the IFT Annual Meeting. The winning teams from the eight areas then compete in a final competition at the Annual Meeting.

Jesus Garcia, Dr. Creasy, Johnna Pieniazek, & Dr. Chew

The award is given to a professor who is an exceptional teacher and who has demonstrated outstanding mentorship to underclassmen in our college. It was established by the Marion family through the Association of Former Students of Texas A&M University in memory of Dr. Potts to recognize a faculty member in the College of Agriculture and Life Sciences who teaches and mentors freshmen and sophomore students and is an effective communicator. Recipients of the award are selected by the members of the College of Agriculture and Life Sciences Student Council.

Dr. Richard Potts ’45 was a respected administrator and faculty member in the College of Agriculture and Life Sciences who contributed to the success of Texas A&M University. He loved and respected his students like his own children, knowing that sometimes they just needed someone to talk to. Dr. Potts was a great mentor to David Marion, who benefited greatly from Dr. Potts mentorship during his time as a student at Texas A&M University, and the award was begun in 2012 by his family as a tribute to Dr. Potts.

Creasy’s experience in food science and nutrition spans from the food industry to higher education and community outreach.  Her instructional focus at Texas A&M has been on introductory nutrition courses, study abroad programs, and undergraduate food science courses. She enjoys mentoring both graduate and undergraduate students as a Leadership Coach with the Maroon & White Leadership Program, as well as an advisor for the Institute of Food Technologists Student Association, the Aggie Golden Arrows Women’s Leadership Organization, and the Omega Phi Alpha Service Sorority. She has also led Study Abroad Texas – Food Science and co-led the Mediterranean Nutrition and Food Processing Study Abroad, and recently coordinated the 2018 Texas FFA Food Science Career Development Event Clinic.

Creasy received a BSA in Food Science from the University of Georgia and a PhD in Food Science and Human Nutrition, and minor in Agricultural Education and Communication, from the University of Florida.

Texas A&M AgriLife researchers develop dietary cancer prevention strategies related to stem cells

2Jun

COLLEGE STATION – Texas A&M AgriLife scientists have found a way to use novel combinations of dietary compounds to selectively delete damaged stem cells and suppress cancer-causing cell signaling.

“This research is necessitated by the fact that the number of cancer cases diagnosed annually by 2050 is likely to double as a result of current population aging,” explained Dr. Robert Chapkin, Texas A&M AgriLife Senior Faculty Fellow and Regents Professor in the department of nutrition and food science, College Station. “If we as a society hope to head off the coming storm, we must get more serious about cancer prevention. Therefore, stem cell targeted therapeutic strategies aiming to eradicate malignancies are necessary.”

Chapkin, also a Texas A&M AgriLife Research nutrition scientist, was recently recognized by the National Cancer Institute as an R35 Outstanding Investigator. His work and that of others in the Chapkin lab focuses on chronic disease prevention.

“We examine the effects of diet and gut microbe-derived bioactives on the inhibition or activation of genes involved in cancer development in humans,” he said.

Chapkin said work initiated by Eunjoo Kim, a graduate student in his lab, recently demonstrated long-chain omega-3 fatty acids found in fish oil have synergistic effects when combined with curcumin, which is found in turmeric, in dramatically reducing colon cancer risk.

“We applied this combination of bioactives in order to target leucine-rich repeat-containing G-protein coupled receptor 5, or Lgr5, stem cells, the cells-of-origin of colon cancer,” he explained. “Specifically, adult colonic Lgr5 stem cells preferentially damaged by carcinogenic activity are removed efficiently via programmed cell death.”

Chapkin said the ability to remove genetically damaged cells is important because residual DNA damaged Lgr5 stem cells generate defective progenitor cells and promote uncontrolled cell proliferation, which can be a factor in tumor development.

“Findings from current studies suggest that unique metabolites produced by microbes in the large intestine following the ingestion of curcumin, when combined with omega-3 fatty acids, are effective as colorectal cancer preventive agents,” he said. “Combination treatment of omega-3 fatty acids with curcumin results in a synergistic efficacy above and beyond omega-3 fatty acids or curcumin alone in deleting damaged Lgr5 stem cells at the tumor initiation stage.”

He said the same synergy is found at the pre-tumor stage of tumorigenesis in colon cancer.

“We demonstrated that omega-3 fatty acids combined with curcumin decreased levels of nuclear beta-catenin, which is a colon cancer marker protein,” he said. “In general, curcumin has a low bioavailability, but omega-3 fatty acids appear to maximize their chemo-protective effect.”

Researchers in his lab have made strides in explaining how the signaling nodes in Lgr5 stem cells are modulated by these dietary bioactives.

“We found that in the presence of carcinogen, omega-3 fatty acids combined with curcumin selectively act on Lgr5 stem cells by up-regulating the p53 signaling pathway in order to remove DNA damaged cells,” said Kim. “The p53 is a tumor-suppressor gene and functions mainly as a gatekeeper and caretaker for the cell. Gatekeepers regulate cellular functions involved in cell growth and cell death and caretaker genes control cellular process involved in stem cell repair of damaged genes and maintain genetic integrity.”

Chapkin also cited recent findings from Natividad Roberto Fuentes, a doctoral candidate in the lab, demonstrating that omega-3 fatty acids actually get incorporated into phospholipids that form the cell plasma membrane, while curcumin squeezes in between spaces within the membrane, leading to modulation of lipid and protein interactions.

“This suggests that their accumulation in the colon can disrupt the membrane structure and composition of epithelial stem cells, and helps suppress dysfunctional Wnt/beta-catenin signaling that can lead to colon cancer,” Chapkin said. “This is noteworthy, because Wnt/beta-catenin signaling controls intestinal stem cell fate and aberrantly activated Wnt signaling is found in colon cancer stem cells but not in normal cells.”

Chapkin said other Wnt repression strategies exist as therapeutic options for colon cancer, but diet-induced Wnt inhibition could represent a valuable alternative strategy for primary cancer prevention.

“Overall, these recent findings suggest that our therapeutic strategy for eliminating damaged stem cells and suppressing Wnt signaling using dietary and microbial bioactives could represent a novel target for the prevention of colon cancer and possibly other cancers,” Chapkin said.
