Dr. Marcia Pierce's grant to EKU's University Research Committee was fully funded to conduct bacterial research through the use of RNA molecules. Participating in this research project will be Jeremiah Alexander.
The following is the abstract of Dr. Pierce's proposal:
Our hypothesis is that short interfering RNA molecules will lead to a significant decrease in the level of resistance proteins produced by Streptococcus pyogenes, leading to a loss of that resistance in the bacteria. Previously in my lab, we have identified more than 20 strains of S. pyogenes that carry resistance genes that allow them to escape the effect of the antibiotic erythromycin, a member of the macrolide drug group. We plan to use a new technology to interfere with the resistance of the bacteria through the use of short, interfering RNA molecules. In order to do this, we must first choose one strain of S. pyogenes from our collection for DNA sequencing. After we have the complete genetic sequence for the strain, we will determine the protein sequence of the resistance gene (either ermB, ermTR, or mefA) using bioinformatics sites such as NCBI Sequence or Swiss-Prot. We will then design siRNA (small interfering RNA) sequences that will reduce translation of the resistance protein made by Streptococcus pyogenes. Using delivery systems including but not limited to nanoparticles (100 nm in diameter), we plan to deliver siRNA into the cytoplasm of the bacterium. We will then determine whether there is any sort of change in the antimicrobial resistance of the strains, using a simple plate diffusion assay. We also intend to develop an ELISA system to detect levels of proteins produced in the bacteria. Finally, we will use RT-PCR to detect measurable messenger RNA levels in the bacteria.
Congratulations to Dr. Pierce and Jeremiah!! |

Dr. Ross Clark's grant to EKU's University Research Committee was fully funded to conduct forest ecology research through the use of systematic botany and tree ring analysis. This research project will make up the majority of Kacie Tackett's masters thesis. Kacie is conduting her research under the guidance of Drs. Ross Clark and Neil Pederson.
The following is the abstract of Dr. Clark's proposal:
We have a unique and time-limited opportunity. Forest disturbance and climate change are crucial influences on the composition, structure and change of forests through time. The old-growth forest remnants we propose to study (Kentucky mixed-mesophytic forest) are among the world’s most complex and diverse temperate forests. Eastern hemlock (Tsuga canadensis) is one of the few dominant conifer trees in these forests. Hemlock fulfills a unique ecological role: it is long-lived (250-450 years), extremely shade-tolerant, slow growing, and provides irreplaceable habitat for many plant and animal species. However, hemlock is becoming critically endangered throughout its range because of an introduced Asian insect, the hemlock woolly adelgid (HWA). This insect already has decimated hemlock forests from Maine to Georgia. Mortality of untreated trees is 100%, and most wild trees cannot be treated because of their inaccessible locations. The HWA was reported recently in far southeastern Kentucky, and is spreading westward. This study will investigate the forest composition (through sampling), and age structure, climatic influences, and disturbance history of two of Kentucky’s hemlock-dominated old growth forest remnants prior to the arrival of the HWA. The study will include the establishment of permanent sample plots, so the original condition and composition of the forest can be compared later to changes which will occur after the loss of hemlock.
Baseline data from this study should be helpful in suggesting future regional management options for forests of this type after the HWA has largely eliminated the hemlocks and the climate has warmed further. The long range impact of HWA on hemlock will be comparable to the effect chestnut blight had on American chestnut trees in the early 20th century. We will never be able to replace the hemlocks once they are lost, but we hope to learn more about the impact of their loss so we can make informed decisions about possible future mitigation and forest management options to help assure the continuation of healthy forests in our region.
Congratulations to Dr. Clark and Kacie!! |

May, 2007:

Participants of the Marine Biology and Coral Reef Ecology field trip to Belize soaking in the tropical atmosphere.
The Marine Biology (Bio 340) and Coral Reef Ecology (Bio 802) classes embarked May 13 - 20 on a trip to the barrier reef of Belize. A total of 14 students went on the trip as did Dr. Nick Santangelo. The trip was coordinated by Guenter Schuster, the instructor of the courses. We joined a similar group from the University of Illinois (led by Dr. Chris Taylor) while we were there, which made for nice cross-university experiences. We stayed the week on the Island of Ambergris Caye at the marine educational station Belize Marine Trec, which is operated by Dr. Ken Mattes and his wife Maureen. The week’s activities included daily trips to the coral reef, on the boat Goliath captained by Capt. Norman. Usually we were able to snorkel at three or more locations each day. One night we had pizza on board and then did a night snorkel on the reef to observe the changes of the reef at night. We also visited a mangrove forest and did a night beach seine, and one night Dr. Mattes lectured to us on the history and culture of Belize. It wasn’t all work, most evenings students were able to enjoy the night life of San Pedro Town, the only city on the caye. The main highlight of the trip was studying the glorious diversity of life on the reef, not the least of which included close encounters with sea turtles, a manatee, dolphins, moray eels, sharks and rays, in addition to the hundreds of coral reef fish species and invertebrates and marine plants of many phyla. Another delight of the trip was the world famous Chicken Drop, recently highlighted on the Travel Channel. Our own Rachel Rowe and Tyler Hansen won the event and treated us with beverages afterwards at Fido’s.

April 16, 2007:
Through the efforts of the Department of Biological Sciences' Dr. Pat Calie, Eastern Kentucky has been selected to receive a grant from LI-COR's Genomics Education Matching Funds program in the amount of $52,152.00 toward the Sequencing, Microsatellite, and AFLP¨ Package. This package will enable EKU to conduct the following research:
Sequencing - DNA Sequencing of single stranded, double stranded, or
PCR products. Labeled infrared primers are the primary chemistry for
most of your reactions, with infrared terminators available for
special situations (e.g. single pass sequencing of a particular
region).
Microsatellites - Microsatellite genotyping of diploid organisms for
biodiversity, forensic, mapping, or association analysis research.
This technique requires knowledge of microsatellite regions for the
target organism.
AFLP - AFLP genotyping of diploid and/or polyploid organisms for
biodiversity or mapping research. AFLP does not require knowledge of
genomic sequence of the target organism.
"This item of equipment will be a major enhancement of our undergraduate teaching and research experience." said Dr. Calie, "The vision that LI-COR is demonstrating is quite remarkable, and most welcome."
