It's likely that you wouldn't have to ask too many of your acquaintances to learn that some they loved died of sepsis. Sepsis, a complication of infection, is one of the leading causes of death in the world. Of the more than one million people diagnosed with sepsis each year in the United States, between 28 percent and 50 percent of them die. It is the tenth leading cause of death among elderly people, and it kills 30% of cancer patients.
Sepsis shock can deprive the organs of blood, triggering widespread organ failure and death. There is little medical personnel can do to help these patients. Currently the only treatment for sepsis is merely supportive in nature, including giving fluids and antibiotics.
Dr. Felix Ikuomola, a PhD candidate in Clinical Research at the John A. Burns School of Medicine (JABSOM) and a Graduate Research Assistant at the University of Hawai`i Cancer Center, has received a $104,477 grant from the National Institutes of Health to fund research he hopes will put natural products from Hawai'i's oceans to work blocking sepsis. He is working in the lab of his mentor, UH Cancer Center Assistant Professor Michelle Matter who
has an NIH R01 (considered the "gold standard" of research grants) funding. Ikuomola's diversity grant is a supplement to Dr. Matter's research.
"My work in Dr. Matter's lab involves screening small molecules, Fungi and Hawaiian marine natural products for potential inhibitory function in endothelial cell permeability," he explains.
An endothelial cell is a thin layer of structural and functional cells that cover the innermost part of blood and lymphatic vessels. Endothelial cells are responsible for many tissue responses including selective permeability of liquids & small chemicals, host-defense reactions to bacteria, repairs to injured cells, signaling between cells, cell proliferation, vascular smooth muscle tone, and cell migration to injured areas. Injury or damage to endothelial cells result in breakdown in barrier function, causing widened pores in the vascular lining that allow cancer to spread, as well as sepsis, edema, and other vascular life-threatening conditions.
Motivated by deaths close to him
Dr. Ikuomola, a U.S. citizen originally from Nigeria, is inspired to save lives because he has seen so many people lose their own struggle with disease, including members of his family.
"While in Africa, I felt frustrated to see my patientsâespecially the surgical patients with sepsisâ without any treatment options. If there had been a pro-endothelial cell barrier enhancing therapeutics, my patient's lives could have been prolonged," said Dr. Ikuomola.
Dr. Ikuomola points out that the same molecular endothelial permeability mechanism also has been implicated in Diabetes Mellitus and Hypertension, the two major leading causes of disease and death in Africans, African-Americans, and Afro-Caribbeans.
"For me, to be involved in vascular biology research is very personal, because when I was seven years old, I lost my beloved father to Hypertension-induced hemorrhagic stroke and cousins to diabetic coma. My patients and family have been the driving force for me to be involved in sepsis research," said Ikuomola.
Why natural marine products?
His special interest is to understand, at the molecular level, how endothelial cells activate endothelial cell permeability to promote leakiness, and how these cells can also activate different pathways to promote endothelial cell barrier integrity and block leakiness. His work in Matter's lab involves screening small molecules, Fungi and Hawaiian marine natural products to potentially inhibit function in endothelial cell permeability.
The complex structure and diversity of natural products plays major role in target-binding selectivity, protein interactions, specificity, and other bio-molecular activities. "We are very hopeful that these Hawaiian marine natural products will work in sepsis because the marine natural products are able to survive the harsh and salty conditions of the ocean and able to control and regulate their internal conditions," said Ikuomola. These marine natural products regulate their cells in such a way that they do not suffer from a hyper-permeability condition which could have led to the uncontrollable influx of ocean water or efflux of cellular contents. "So, this property that maintains the cell integrity of th natural products is encouraging."
More about Dr. Ikuomola
Dr. Ikuomola is quick to thank those who have inspired and supported his work, and helped him receive the new grant. "I am very grateful to God; my wife Wendy; my mother; Dr. Rosanne Harrigan (JABSOM Director of Faculty Development); Dr. Michelle Matter; Dr. Joe Ramos; my colleagues at the UH Cancer Center Matter Lab; and The National Institutes of Health National Institute of General Medical Science for this diversity supplement grant," he said.

Five Ways the UH Cancer Center Benefited Hawaii in the Past Year
Clinical Trials: providing leading edge cancer care for Hawaii's people
- The University of Hawaii Cancer Center, working with Hawaii hospitals and physicians, gave Hawaii's adult and pediatric cancer patients access to around 100 different national clinical trials of new treatments and technologies.
- This means that Hawaii's cancer patients did not have to leave the islands to access potentially better care and had the earliest opportunity to receive life-saving treatment breakthroughs.
- In so doing, the Center substantially contributed to keeping Hawaii's cancer care providers who offer clinical trials for their patients at the cutting edge. Clinical trials guarantee patients receive the national standard of best care and have the opportunity to benefit from treatment innovations.
Research: improving cancer care, prevention and survivorship
- Cancer Center researcher Thomas Wills, PhD, uncovered a growing public health problem among Hawaii's youth. His research conducted in Hawaii high schools confirmed that rates of e-cigarette use by Hawaii adolescents are at least double the rate of e-cigarette use observed in studies of mainland adolescents. Furthermore, his study published in the peer-reviewed journal Pediatrics clarified a reason why e-cigarette use is growing nationally among teens, as his data suggest that e-cigarettes may be operating to recruit lower-risk adolescents to smoking.
- A Hula Study for Breast Cancer Survivors was begun and is now in progress to assess whether hula can be an effective strategy to increase physical activity after treatment. Studies have shown that physical activity is important for reducing the chance of cancer recurrence.
- The Cancer Center began research to increase screening rates for colon cancer among Native Hawaiian men in hopes of reducing the high rate of cancer deaths in this population.
- Cancer Center researchers assembled a library of more than 2,586 natural products from Hawaii natural resources for testing against human tumors. Researchers have identified many drug leads, including two natural product compounds from plants (such as poha berry), one compound from sea sponge, and two compounds from microbial sources, which inhibit growth of human breast, brain, or ovarian cancers in experimental models.
Economic Development: to stimulate job creation and build Hawaii's future
- The Cancer Center brought in $20 million in grants that supported cancer research in Hawaii. This money directly supported the economy of Hawaii.
- The Cancer Center assisted researchers with technology development and patent activity in order to grow new revenue streams and assist with the development of new companies from this intellectual property. The Cancer Center supports the state's Innovation Initiative to develop Hawaii's technology sector.
- Three patents have been filed in the last 1-2 years from research looking at natural products. The intellectual property rights to a natural product that was discovered by Cancer Center researchers have been licensed to a major pharmaceutical company with the goal of developing a new treatment for cancer. The compound (cryptophycin) has been licensed to Sanofi-Aventis.
Outreach: to give reliable information to help end cancer
- The Cancer Center through its Hawaii Tumor Registry division assemble the data necessary for Hawaii cancer statistics, including the next update (currently in progress) of the Hawaii Cancer Facts & Figures.
- Cancer Center faculty and staff are working with the state Department of Health and other Hawaii cancer stakeholders on the next revision of the Hawaii State Cancer Plan, a strategic initiative to end cancer in our state.
- Free Cancer Center public events for Hawaii residents deliver cutting edge information on cancer survivorship (from all cancers), as well as, specific information on breast cancer and prostate cancer. Many public educational events are held at the Sullivan Conference Facility in the Cancer Center.
- Cancer Center employees distributed cancer information at health fairs, neighborhood events, senior citizen fairs, and other venues.
- Cancer Center tours were given to groups of students, visitors, and senior citizens.
Educating Hawaii's Youth: giving Hawaii students opportunity and training
- Two dozen interns from Hawaii high schools and colleges, plus Hawaii students attending college in mainland schools, were trained in cancer research through the Cancer Center's summer internship program.
- Students from disadvantaged backgrounds receive educational and research opportunities through the Cancer Center using public/private grant funding.
- Additional college interns work in various areas of the Cancer Center throughout the year.

Dr. Lana Garmire and team win University of Hawai'i Cancer Center's Publication of the Monthby Chantal Jackson
HONOLULU, HI - Dr. Lana Garmire won University of Hawai'i Cancer Center's November Publication of the Month award for her collaborative paper, "mirMark: a site-level and UTR-level classifier for miRNA target prediction," printed on October 25th 2014 in Genome Biology. Dr. Lana Garmire is a tenure-track assistant professor in the Cancer and Epidemiology Program at University of Hawai'i Cancer Center.
Micro RNA (miRNA) is a type of small RNA that regulates genes; markedly, miRNA plays an important role in cancer, and other diseases. Specifically, miRNAs regulate gene expression by binding to untranslated regions (UTRs) of mRNA.
Currently, other computational methods to predict miRNA targets are inadequate. In their study, three PhD students Mark Menor, Travers Ching, Xun Zhu, together with collaborator Dr. David Garmire, and senior corresponding author Dr. Lana Garmire employed machine learning methods and most comprehensive databases determine miRNA binding; in particular, if a specified gene is a miRNA target or not. This method is capable of miRNA target prediction at the site-level and gene-level. It achieves significantly better prediction than other tools, including TargetScan the most popular tool developed by David Bartel's group at MIT.
Dr. Lana Garmire explains, "The present goal is to determine if a gene sequence is a target of miRNA, which can be done at two levels: a coarse level (UTR-level), or a fine level (Site-level)." Dr. Garmire further highlights the general application for this miRNA target prediction approach, "We want to improve the inconsistency and overlap associated with different predictive tools, and this will help us better understand miRNA's functions in cancer. In this manner, knowledge-based guidance will be provided to molecular biologists for their experiments."
miRNAs are indicated as good biomarkers and therapeutic candidates for various cancers including breast, prostate and liver. The method discussed in this report will theoretically improve experimental research of such diseases, and ultimately serve to improve the lives of individuals enduring them.
