Live 11:00 AM- 12:00 Mediterranean Diet and Lifestyle: A Symposium on Diet and Human Health : Opening Remarks October 19, 2018

Reporter: Stephen J. Williams, Ph.D.

11:00 Welcome

 

 

Prof. Antonio Giordano, MD, PhD.

Director and President of the Sbarro Health Research Organization, College of Science and Technology, Temple University

Welcome to this symposium on Italian lifestyle and health.  This is similar to a symposium we had organized in New York.  A year ago Bloomberg came out with a study on higher longevity of the italian population and this study was concluded that this increased longevity was due to the italian lifestyle and diet especially in the southern part of Italy, a region which is older than Rome (actually founded by Greeks and Estonians).  However this symposium will delve into the components of this healthy Italian lifestyle which contributes to this longevity effect.  Some of this work was done in collaboration with Temple University and sponsored by the Italian Consulate General in Philadelphia ( which sponsors programs in this area called Ciao Philadelphia).

Greetings: Fucsia Nissoli Fitzgerald, Deputy elected in the Foreign Circumscription – North and Central America Division

Speaking for the Consulate General is Francesca  Cardurani-Meloni.   I would like to talk briefly about the Italian cuisine and its evolution, from the influence of the North and South Italy, economic factors, and influence by other cultures.  Italian cooking is about simplicity, cooking with what is in season and freshest.  The meal is not about the food but about comfort around the table, and comparible to a cullinary heaven, about sharing with family and friends, and bringing the freshest ingredients to the table.

Transcription is a cellular process by which genetic information from DNA is copied to messenger RNA for protein production. But anticancer drugs and environmental chemicals can sometimes interrupt this flow of genetic information by causing modifications in DNA.

Chemists at the University of California, Riverside have now developed a test in the lab to examine how such DNA modifications lead to aberrant transcription and ultimately a disruption in protein synthesis.

The chemists report that the method, called “competitive transcription and adduct bypass” or CTAB, can help explain how DNA damage arising from anticancer drugs and environmental chemicals leads to cancer development.

“Aberrant transcription induced by DNA modifications has been proposed as one of the principal inducers of cancer and many other human diseases,” said Yinsheng Wang, a professor of chemistry, whose lab led the research. “CTAB can help us quantitatively determine how a DNA modification diminishes the rate and fidelity of transcription in cells. These are useful to know because they affect how accurately protein is synthesized. In other words, CTAB allows us to assess how DNA damage ultimately impedes protein synthesis, how it induces mutant proteins.”

Study results appeared online in Nature Chemical Biology on Aug. 19.

Wang explained that the CTAB method can be used also to examine various proteins involved in the repair of DNA. One of his research group’s goals is to understand how DNA damage is repaired—knowledge that could result in the development of new and more effective drugs for cancer treatment.

“This, however, will take more years of research,” Wang cautioned.

His lab has a long-standing interest in understanding the biological and human health consequences of DNA damage. The current research was supported by the National Cancer Institute, the National Institute of Environmental Health Sciences and the National Institute of Diabetes and Digestive and Kidney Diseases of the National Institutes of Health.

Wang was joined in the research by UC Riverside’s Changjun You (a postdoctoral scholar and the research paper’s first author), Xiaoxia Dai, Bifeng Yuan, Jin Wang and Jianshuang Wang; Philip J. Brooks of the National Institute on Alcohol Abuse and Alcoholism, Md.; and Laura J. Niedernhofer of the University of Pittsburgh School of Medicine, Penn.

Next, the researchers plan to use CTAB to investigate how other types of DNA modifications compromise transcription and how they are repaired in human cells.
