RESUMO

The Kansas-IDeA Network of Biomedical Research Excellence (K-INBRE) is an infrastructure-building program funded by the National Institute of General Medical Sciences. Undergraduate education, through undergraduate research, is a key component of the program. The K-INBRE network includes 10 higher education institutions in Kansas and northern Oklahoma, with over 1,000 student participants in 16 yr. Since 2003, the K-INBRE has held an annual state-wide research symposium that includes national and regional speakers and provides a forum for undergraduates to give platform and poster presentations. The symposium is well attended by K-INBRE participants and has grown to a size of over 300 participants per year from all 10 K-INBRE schools. Two surveys were distributed to students and mentors to assess the impact of the symposium on student learning. Surveys (153) were distributed to students who participated in K-INBRE from 2013 through 2015 with a 51% response rate. Mentors were surveyed with a response of 111 surveys out of 161. Survey results indicate that students and mentors alike find the symposium to be beneficial and enriching of the student experience. Almost 80% of student respondents indicated that their participation in the symposium fostered appreciation of research. In short, the K-INBRE symposium provides a unique opportunity for students to gain experience in collecting, preparing, and communicating research in a professional environment. The collaborative experience of the annual K-INBRE symposium, the impact it has on student learning, and how it has influenced the research culture at our 10 institutions will be described.

RESUMO

We recently reported the inflammation of the cystic fibrosis (CF) mouse small intestine, and we hypothesized bacterial overgrowth as a possible cause. Quantitative PCR of bacterial 16S genomic DNA in the CF mouse small intestine revealed an increase of greater than 40-fold compared to controls. Sequencing of 16S PCR products and Gram staining showed that the majority of bacteria in the CF mouse intestine were gram negative. Bacteria were observed to colonize the mucus that accumulates in the intestinal lumen of mice with CF. Impaired Paneth cell defenses were suggested by observation of partially dispersed Paneth granules in the mucus plugs of CF mouse intestinal crypts, and this mucus was strongly immunoreactive for Paneth cell bactericidal products. The role of bacterial overgrowth in intestinal inflammation in CF was tested by treating mice with oral antibiotics (ciprofloxacin and metronidazole) for 3 weeks, which reduced bacterial load in the CF mouse small intestine over 400-fold. Antibiotic treatment decreased the expression of the inflammation-related genes mast cell protease 2, leucine-rich alpha2 glycoprotein/leucine-rich high endothelial venule glycoprotein, suppressor of cytokine signaling 3, hematopoietic cell transcript 1, and resistin-like molecule beta/found in inflammatory zone 2, all of which were no longer expressed at levels significantly different from control levels. The reduction of intestinal bacteria also significantly improved the growth of CF mice but had no effect on the growth of wild-type mice. These data suggest that bacterial overgrowth in the CF mouse small intestine has a role in inflammation and contributes to the failure to thrive in this mouse model of CF.
