$175K in pilot grants awarded to UC cancer researchers

Pilot grants totaling $175,000 were recently awarded to University of Cincinnati (UC) researchers to fund projects dedicated to advancing science and finding new therapies for pancreatic and head and neck cancers.

GIVEHOPE Pancreatic Cancer Research and Awareness Fund: 

$47,500 to Xiaoyang Qi, PhD, professor in the Division of Hematology Oncology, member of the Cincinnati Cancer Center and UC Cancer Institute. Qi and his team will study a cellular structure and function in metastatic pancreatic cancer cells and determine the therapeutic efficacy of nanovesicles by blocking certain cancer-causing pathways in cancer development and spread. 

$47,500 to Fukun Guo, PhD, associate professor in the Department of Pediatrics and a researcher at Cincinnati Children’s. Guo and his team will determine the efficacy of chemical targeting of animal and human regulatory T cells (a type of white blood cells) as a way to trigger immunity against pancreatic tumor formation.

Steven Goldman Memorial Pancreatic Cancer Research Grant:

$55,000 to Yana Zavros, PhD, professor in the Department of Pharmacology and Systems Physiology, and her team. As Zavros received funds from the Goldman grant last year, her continuing project will focus on putting individual pancreatic cancer patient immune cells into an organoid culture to predict the best treatment for that person. An organoid is a three-dimensional, multicellular miniaturized version of the tissue or organ from which it was derived. The hope is that this personalized assessment will improve outcomes for patients.

Brandon C. Gromada Head and Neck Cancer Foundation Research Fund:

$25,000 to Vinita Takiar, MD, PhD, assistant professor in the Department of Radiation Oncology and member of the UC Cancer Institute, and her multidisciplinary team including medical oncologist Trisha Wise-Draper, MD, surgeon Alice Tang, MD, and post-doctoral fellow Christina Wicker, PhD. Their project will collect pilot data for a new approach to treatment of head and neck cancers by looking first at patient-derived organoids. Growing tumors in the lab directly from patients will provide the researchers with a new way to study head and neck cancers and test treatment options.

UC researchers say early puberty in girls may be the new big...

CINCINNATI—Adolescent girls who reach puberty at an earlier age may also have a greater chance of developing migraine headaches, according to new research from investigators at the University of Cincinnati (UC) College of Medicine. “We know that the percentage of girls and boys who have migraine is pretty much the same until menstruation begins,” says Vincent Martin, MD, professor in the Division of General Internal Medicine and director of the Headache and Facial Pain Center at the UC Gardner Neuroscience Institute. “When the menstrual period starts in girls, the prevalence goes way up, but what our data suggests is that it occurs even before that.” The findings will be presented by Martin at the American Headache Society 61st Annual Scientific Meeting Saturday, July 13, in Philadelphia. Nationally, about 10 percent of school age children suffer from migraine, according to the Migraine Research Foundation (MRF). As adolescence approaches, the incidence of migraine increases rapidly in girls, and by age 17, about 8 percent of boys and 23 percent of girls have experienced migraine, the MRF reports. Martin and a team of researchers were part of a longitudinal study looking at 761 adolescent girls from sites in Cincinnati, New York and the San Francisco Bay area. The girls ranged in age from 8 to 20 and study took place over a 10-year period beginning in 2004. Girls enrolled in the study at age 8-10 were examined during study visit every six to 12 months. Researchers determined when they showed initial signs of thelarche (breast development), pubarche (pubic hair growth) and menarche (start of menstrual periods). Girls answered a headache questionnaire to find out if they suffered from migraine headache, no migraine or probable migraine—the latter is defined as meeting all the diagnostic criteria for migraine except one. The average age at which they completed the survey was 16. Of those surveyed, 85 girls (11 percent) were diagnosed with migraine headache while 53 (7 percent) had probable migraine and 623 (82 percent) had no migraine, according to Martin, also a UC Health physician specializing in migraine. Researchers found that girls with migraine had an earlier age of thelarche (breast development) and the onset of menarche (menstrual periods) than those with no migraine. On average breast development occurred four months earlier in those with migraine while menstruation started five months earlier. There was no difference in the age of pubarche (pubic hair development) between those with migraine and no migraine. “There was a 25 percent increase in the chance of having migraine for each year earlier that a girl experienced either thelarche or menarche,” says Susan Pinney, PhD, professor in the UC Department of Environmental Health and lead investigator on the study. “This suggests a strong relationship between early puberty and the development of migraine in adolescent girls.” The age of onset of thelarche, pubarche or menarche did not differ between those with probable migraine and no migraine, says Pinney. Previous research suggests that migraine often starts with the onset of menstrual cycles during menarche in adolescent girls. But this study looks at earlier stages of puberty such as thelarche and pubarche, explains Martin. “To suggest the origins of migraine may occur actually before menstrual periods begin is pretty novel,” says Martin. “At each of these stages, different hormones are starting to appear in girls. During pubarche, testosterone and androgens are present, and during thelarche, there is the very first exposure to estrogen. Menarche is when a more mature hormonal pattern emerges. Our study implies that the very first exposure to estrogen could be the starting point for migraine in some adolescent girls. It may be the Big Bang Theory of migraine.” So is there anything that one can do to prevent an early puberty? “Studies suggest that childhood obesity is associated with early puberty,” says Martin, who is also president of the National Headache Foundation. “Keeping your weight down might prevent the early onset of puberty. Future studies will need to be done to determine if strategy will decrease also the likelihood of developing migraine.” Other co-investigators in the study include Frank Biro, MD, UC professor in the Department of Pediatrics and Cincinnati Children’s pediatrician, Jun Ying, PhD, professor in the UC Department of Environmental Health, and Hao Yu, biostatistician, UC Department of Environmental Health. Funding for this research came grant U01ES026119 from the National Institute of Environmental Health Sciences and grant 1R03HD094236 of the Eunice Kennedy Shriver National Institute of Child Health and Human Development.
