Study focuses on potential lung cancer therapies

HUNTINGTON, W.Va. – Scientists from Marshall University, Piyali Dasgupta, Ph.D.along with colleagues at Alderson-Broaddus College in Philippi, have completed a study that may eventually help lead to the development of new treatments for lung cancer.

Their results were published in the Feb. 15 issue of Cancer Research, the most frequently cited cancer journal in the world.

At Marshall, Dr. Piyali Dasgupta, associate professor in the Department of Pharmacology, Physiology and Toxicology in the Joan C. Edwards School of Medicine, worked on the study with her research team of Jamie Lau, Kathleen Brown and Brent Thornhill, and undergraduate students Cody Stover and Christopher McNees.

Researchers in Dasgupta’s lab explore how the various components of tobacco, especially nicotine, advance the progression of lung cancer.                                       

Dasgupta said this study focused on a specific type of lung cancer called bronchioalveolar carcinomas, or BACs, which are known to be associated with smoking. She and the other scientists working on the project looked at the cellular pathways through which nicotine—the addictive component in cigarettes—promotes the growth and survival of BACs. 

According to Dasgupta, nicotine itself is not a carcinogen, but studies have shown it can induce the growth and metastasis of lung cancers. It can also protect lung cancer cells against the beneficial effects of chemotherapy.

She said, “In this study, we found that nicotine raised the levels of specific neurotransmitters, or ‘chemical messengers,’ in human BACs. When we used a drug, vesamicol, to interrupt the neurotransmitters’ pathways, the nicotine-induced growth of these carcinomas was significantly suppressed. Our findings are important because they indicate that agents like vesamicol may be useful in the treatment of human lung cancers.”

The study was funded in part by a Young Clinical Scientist Award from the Flight Attendant Medical Research Institute.

Marshall biomedical sciences’ researchers publish e-book on nutrition and cancer

Cover of "Nutrition and Cancer: From Epidemiology to Biology"Researchers at Marshall University’s Joan C. Edwards School of Medicine have collaborated on an electronic book, “Nutrition and Cancer From Epidemiology to Biology,” recently published by Bentham Science Publishers.

This ebook is one of the latest efforts of researchers at the Marshall University Nutrition and Cancer Center.

A collection of scientific articles written by Marshall faculty members and students, the publication was edited by Dr. Richard M. Niles, professor and chairman of the university’s Department of Biochemistry and Microbiology, and Dr. Pier Paolo Claudio, associate professor in the Department of Biochemistry and Microbiology and director of the McKown Translational Genomic Research Institute.

According to the publisher, various estimates suggest that between 30-40% of all human cancers are related to dietary patterns. Strong epidemiological evidence from studies points to dietary constituents that either contribute or protect against the development of various forms of cancer.

This e-book reviews some traditional and relatively new areas of nutrition and cancer. Epidemiological data is combined with molecular biology research and, where available, clinical trial data. The emerging science of “Nutrigenomics” is discussed with chapters on the biological role of various nutrition components from red wine, peppers, green tea, fish oil, cruciferous vegetables, retinoids; and the intersection of nutrition and epigenetics in hematopoiesis.

The publication will be of interest to researchers in the nutrition and cancer fields, physicians in family and community medicine, internal medicine and oncology, and dieticians providing counseling to cancer patients and cancer survivors.

BMS associate professor plays significant role in heated tobacco debate

by Saeed Keshavarzian, BMS Medical Sciences student

Piyali Dasgupta, Ph.D.Marshall’s Student Government Association (SGA) recently held a meeting to vote on a campus-wide tobacco ban. Marshall University President Stephen J. Kopp asked Student Body President Ray Harrell Jr. to form a joint committee to draft a proposal for Marshall University to go tobacco free. The committee drafted the proposal to ban all tobacco products campus-wide.

Dr. Piyali Dasgupta, Associate Professor of Pharmacology, Physiology and Toxicology in the Joan C. Edwards School of Medicine was asked by Amy Saunders, Director of Student Health Education Programs, to attend the meeting in order to explain the effects of nicotine on the human body, and to answer any questions that the gallery had regarding the ill effects of nicotine. 

Early into the meeting Dr. Dasgupta explained that nicotine “can promote tobacco related diseases,” one of which is lung cancer. She also stated that her lab is performing research on the “ill effects of second hand smoke, even third hand smoke, which is the stuff that sticks to your car, [and] to your clothes when you smoke.” As the gallery was allowed to ask questions and voice concerns, Dr. Dasgupta answered health-related questions that were asked. After two hours of heated debate and testimonials from both the SGA senators and the gallery, the SGA voted 11-7 in favor of the campus-wide tobacco ban.

Dr. Piyali Dasgupta awarded NIH grant for lung cancer research

Piyali Dagupta, Ph.D., and Monica Valentovic, Ph.D.HUNTINGTON, W.Va. – A Marshall University faculty member has been awarded a three-year, $426,000 grant by the National Institutes of Health (NIH) to further her lung cancer research.
 
Dr. Piyali Dasgupta, associate professor in the Department of Pharmacology, Physiology and Toxicology in the university’s Joan C. Edwards School of Medicine, will use the grant to continue her work to determine if the nutritional agent capsaicin—the active ingredient in chili peppers—can improve the anti-cancer activity of the commonly used chemotherapy drug cisplatin in patients with small cell lung cancer.
 
Dasgupta received the funding through the National Cancer Institute’s Academic Research Enhancement Award program. The program supports research projects in the biomedical and behavioral sciences that strengthen the research environment of the institution and expose students to research. Her co-investigator is Dr. Monica Valentovic, a professor in the same department.
 
“Small cell lung cancer is characterized by a high rate of growth, early metastasis and a dismal survival rate,” said Dasgupta. “Although chemotherapy works well initially in these patients, they often relapse quickly and become unresponsive to chemotherapy. Since the preliminary data in our laboratory shows that capsaicin manifests anti-cancer activity in this type of cancer, we are hopeful our studies under this new grant may lead to new treatments.”
 
She continued, “I am thrilled to receive this funding and I am grateful to a lot of people who have been instrumental in our success to this point. My collaborator Dr. Valentovic is a fabulous scientist to work with. I am also grateful to all the members of my lab for their hard work and dedication.”
 
Dasgupta also acknowledged the support of the chairman of her department, Dr. Gary Rankin, and acknowledged Dr. Marcia Harrison and the MU-ADVANCE program, which she says made it possible for undergraduate students to work in her lab. MU-ADVANCE is a National Science Foundation-funded program to help increase the number of female science and engineering faculty at the university.
 
Dasgupta says she believes her proposal was selected for funding at least in part because the grant program’s focus on student research made it a good match for her lab. Undergraduates working in her lab have a track record of receiving research grants, authoring publications and presenting their findings at international conferences.
 
Dr. John M. Maher, Marshall’s vice president for research, congratulated the researchers, saying, “NIH grants are extraordinarily competitive, and I applaud Drs. Dasgupta and Valentovic for having a successful application. They are doing vital research that may very well have a positive impact on human health in the not-so-distant future. In addition, the grant will allow them to continue to give students hands-on, meaningful research opportunities in the lab.”
 
In addition to receiving the new NIH funding, Dasgupta recently was notified that her grant from the Flight Attendant Medical Research Institute has been renewed for an additional two years. The renewal, which extends the original three-year award, makes the total grant worth nearly $550,000. That grant is funding Dasgupta’s study of how nicotine, the active component in cigarette smoke, facilitates the progression of lung cancer. Valentovic is also the co-investigator on that award.

Drs. Claudio and Niles co-edit and publish an ebook on nutrition and cancer featuring BMS professors and students

Cover of "Nutrition and Cancer: From Epidemiology to Biology"Pier Paolo Claudio, M.D./Ph.D., and Richard M. Niles, Ph.D., of the Biomedical Sciences Graduate Program have co-edited and written articles in an ebook entitled “Nutrition and Cancer: From Epidemiology to Biology.” This ebook is one of the latest efforts of cancer researchers at the Marshall University Nutrition and Cancer Center, where the role of nutrition in cancer is actively and successfully investigated. The ebook contains a collection of scientific articles, written by researchers and students in the Marshall University Biomedical Sciences Graduate Program.  

The purpose of this publication is to educate and inform the public regarding the latest knowledge on nutrition and cancer. It focuses on the role of various nutritional components in cancer prevention, as well their present and future use in cancer therapy. According to Dr. Pier Paolo Claudio, “This e-book will be of interest to researchers in the nutrition and cancer field, physicians in family and community medicine, internal medicine and oncology, as well as dieticians providing counseling to cancer patients and cancer survivors.”

Dr. Niles says that the best description of the importance of this book can be found within the foreword, written by Dr. Gary Meadows of Washington State University:

“While we as individuals cannot modify our genetic makeup and may have little control over the multitude of carcinogens in our environment, we have the power to make healthy diet-based choices that can significantly modify cancer risk and progression. The authors have structured this book not only to review the epidemiological studies that support the roles of selected nutrients/phytochemicals in cancer control, but also they review the cellular and molecular pathways involved in their action as well as the clinical data related to their efficacy in cancer treatment. Consequently, this book has wide appeal not only to researchers in the nutrition and cancer field, but also to oncology practitioners, dieticians, as well as cancer survivors, who are interested learning how healthy dietary choices can enhance their quality of life.” 

According to Dr. Niles, editing the book involved reviewing each chapter and making suggestions for improvement of the content handwriting. He also co-wrote a chapter with Dr. Rankin on resveratrol, found in high concentration in red wine, and its ability to inhibit the development or progression of certain types of cancer. Dr. Claudio co-wrote an article with Ph.D. candidate M. Allison Wolf on isothiocyanates, phytochemicals found in cruciferous vegetables, which his lab found to target carcinogenesis during tumor initiation, promotion, and progression.

The following authors and articles are found within the ebook:
