Short Biography

Dr. Eun-Jung Park earned her Ph.D. in pharmacognosy from Ewha Womans University, with a dissertation entitled “cancer chemopreventive potential of natural product-derived stilbenoids in multistage carcinogenesis”. Dr. Park evaluated the activities of natural products and their analogs on three stages of carcinogenesis, including initiation, promotion and progression, using in vitro cell line based assay. Upon active compounds, Dr. Park studied further to elucidate the molecular mechanisms. She received a Scholar-in-training Award from American Association for Cancer Research (AACR) with her work in 2006. Since then, she is an associate member of AACR. After graduation, Dr. Park joined University of Hawaii as a postdoctoral fellow, and continued her career as a research specialist at the The Daniel K. Inouye College of Pharmacy, University of Hawai’i at Hilo, HI. During this period, she examined the effects of a multitude of samples on nitrite production, aromatase enzymatic activity, free radical production, cancer cell proliferation, transcriptional activity of retinoid X receptor, etc. Various compounds or extracts were found as active, including marine macro- and microorganisms, norsesterterpene peroxides, resveratrol analogs, phenolic glycosides, phenazines, isothiocyanate derivatives, callophycin A analogs, thiadiazole analogs, indenoisoquinolines, sesquiterpene lactones, 2-arylindole derivatives, withanolides, and azaphilones. In 2016, Dr. Park joined College of Pharmacy and Health Sciences, Long Island University as a research scientist. Her current research is focused on the effect of grape-containing diets (regular diet and Western diet) on health and longevity.

Research Synopsis

Grape contains anti-oxidant polyphenols including catechin and resveratrol. The production of reactive oxygen species (ROS) is an inevitable event from aerobic metabolism in mitochondria. ROS might play an important role in aging process via affecting “the hallmarks of aging”, including genomic instability, telomere attrition, epigenetic alterations, loss of proteostasis, deregulated nutrient sensing, mitochondrial dysfunction, cellular senescence, stem cell exhaustion, and altered intercellular communication (López-Otín et al., Cell, 2013). Therefore, we hypothesized that daily intake of grape, as a polyphenol-rich source, in a regular or a Western diet might attenuate aging process and improve health. To my knowledge, it has not been reported on the systemic and in-depth examination on the effects of lifetime consumption of grape. Hence, we aim to measure various biomarkers and gene expression levels in serum and tissues, periodically.
