Studies in animals show as a cancer therapy may be useful for cancer. Clinical research with his that vitamin C infusions can slow those who wish to know where the colleague Ewan Cameron in the 70s tumor growth. A number of studies science stands on this treatment: demonstrated that large doses of are now underway to characterize It is generally safe: Results from oral and intravenous (IV) vitamin C the molecular anticancer controlled clinical trials indicate that were helpful in increasing the survival mechanisms of vitamin C and IV vitamin C is generally safe and well time and improving the quality of life optimal protocols for administration. tolerated in most prescreened cancer of terminal cancer patients. When However, there is plenty of work patients. In fact, there are very few follow-up studies by the Mayo Clinic to be done before vitamin C can be contraindications for vitamin C in using only oral vitamin C did not show accepted as a mainstream therapy intravenous form. However, there is any benefit, many cancer researchers for cancer. still the potential for side effects: those doubted the value of vitamin C therapy, Yet, as clinical researchers try to with existing kidney disease, history and the research slipped out of the understand why and how much of kidney stones, or glucose-6-phos- mainstream. vitamin C can help fight against phate dehydrogenase deficiencies About 10 years ago, studies at the NIH cancer, thousands of people should take particular caution. with Dr. Mark Levine revitalized cancer worldwide are using it as a primary It is not the same as taking a research with vitamin C.

13 LPI GRADUATE STUDENTS

Graduate students are key to the success of the Linus Pauling Institute and research at Oregon State University. In this and future issues of the newsletter, we will highlight our students and their achievements at the Institute.

Melissa McDougall Bayissi Bading Taika Elizabeth Axton

Eventually that developed and Ph.D. candidate at the University town in northern California, where into an interest in cellular biology. of Hertfordshire in London/UK, science careers were undervalued. After obtaining her bachelor’s degree in working in the laboratory of Dr. Fred Always interested in the natural world, molecular and cellular biology with an Stevens. Her project involves she developed a keen interest in emphasis in neuroscience, Melissa came bioactives from a shrub native to metabolomics (see p. 12) after her to Oregon State University to pursue a Gabon and Central Africa called undergraduate years at the University Ph.D. working with Dr. Maret Traber, Tabernanthe iboga.

Her focus is on vitamin E useful in treating obesity and type 2 specifically to work with Dr. Fred Stevens. in the brain, from beneficial functions in diabetes. Currently, she is using metabolomics early development to those found during With a background in molecular to explore the biological effects of old age. She is currently working to biology, cellular biology, biochemistry, nitrates, and she has followed the elucidate the effects of vitamin E deficiency and pharmacology from University interactions of vitamin C, nitroglycerin, on brain function using zebrafish. Paul Sabatier in France, Bayissi was and effects on the cardiovascular Melissa’s hard work has paid off in awarded a grant from the Gabon system. Elizabeth was recently multiple fellowships over the years, Oregon Center, which gave her the awarded first place at the annual and she is currently a Marion T. Tsefalas opportunity to work with Dr. Stevens’ Environmental and Molecular Toxicology Graduate Fellowship awardee.

14 DEVELOPMENTS Dear Friends, Most of you who have read our These students have their own newsletter over the years are familiar accomplishments and awards, but with our wonderful faculty researchers. the size and number of funding However, did you know that the opportunities are limited. Many of Institute is also home to many student our brilliant students work their way researchers? In fact, we have 15 through school, and their families undergraduate researchers and 8 often make great sacrifices to help graduate researchers, many of whom them graduate. Sadly, there are times Amanto Marcotulli, J.D. are Ph.D. candidates. when research funding falls short and Director of Development In this issue, we feature some of our support for these students disappears student researchers so that you can — they simply can’t afford to pay for get a sense of the caliber of their work tuition, books, or living expenses and and the contributions they make work an unpaid position in the towards advancing the cutting-edge laboratory at the same time. When science taking place here at Linus this happens, our research gets held Pauling Institute. Our faculty takes back and students miss out on great pride in mentoring young important learning opportunities. researchers who are just starting their For these reasons, we have careers because educating the next established the Balz Frei Endowed generation of citizen scientists is an Fellowship Fund (in honor of our integral part of our mission. And make former director) to support graduate no mistake, these students play a vital students. I hope that you will consider role in advancing our research goals. making a gift to this fund. Your As a public institution, Oregon State generosity will support LPI’s research University is committed to offering and help hard-working students students access to a high-quality launch their careers. education regardless of their financial Please contact me to learn more background, and this commitment about the Balz Frei Endowed is shared by all of us at the Institute.
