Research (80%):
The Gonda Laboratory is interested in the genetics of susceptibility to
diseases. Although his primary research emphasis is ruminants, he also works on
other species including swine and hamsters. Below are two of the on-going
research projects in our laboratory.
Deciphering the genetics of BVD
vaccine response in cattle. It is oftentimes assumed that vaccine response
is homogenous among animals, but the truth is that animals do not respond
equally to administration of a vaccine. Specifically, our laboratory is
interested in the humoral (antibody) response to vaccination. How much of
the variation in the humoral response to vaccination is caused by genetic
differences among animals?
We are initially focusing our efforts on the response to a
commercially available bovine viral diarrhea (BVD) vaccine. BVD is a virus that
can cause respiratory disease in cattle. If a cow is infected with BVD during
pregnancy, that cow’s calf can become persistently infected with the virus and
shed BVD rapidly to other animals in a herd.
Specifically, we are asking the following questions about the genetics
of BVD vaccine response. 1) Can we identify breeds of cattle that are high or
low responders to BVD vaccination? 2) What genes affect variation in BVD
vaccine response? To answer this question, we will use a combination of
whole-genome and candidate gene approaches. 3) What genes are up- and
down-regulated following vaccination? To answer all of these questions, we will
utilize techniques from several scientific disciplines, including quantitative
genetics, molecular genetics, and functional genomics.
Why is this research important? If we can identify genes that affect
variation in vaccine response, it may assist researchers with developing better,
more robust vaccines. By identifying genes that affect vaccine response, we
could also develop molecular markers for this trait. These markers could be
used to select against cattle that do not respond robustly to vaccines. The end
result is that we could use genetic selection to improve herd health.
We are collaborating with Dr. Christian Maltecca at North Carolina State
University on this project. Below is a link to his biography at NCSU.

The genetics of the
Bio 14.6 hamster. The Bio 14.6 hamster exhibits signs similar to
limb-girdle muscular dystrophy in humans. One of our collaborators at SDSU (Dr.
Doug McFarland) has developed clones of satellite cells (muscle stem cells) from
the Bio 14.6 hamster and control hamsters. When these satellite cells are
differentiated into myotubes, the Bio 14.6 myotubes do not differentiate
normally.
The mutation that causes the abnormal differentiation in the Bio 14.6
hamster has been identified as a defect in a sarcoglycan gene. My main goal
is to understand the genetic pathways that are modified as a result of this
defect. Because the hamster genome has not been sequenced and
hamster-specific microarrays are not available, our first objective will be to
characterize the satellite cell transcriptome of the Bio 14.6 hamster by massive
parallel sequencing (454 sequencing). We will compare the Bio 14.6
transcriptome with control hamsters to identify biological pathways that are
differentially expressed in this mutant hamster strain.
We are collaborating with Dr. Sandy Velleman at The Ohio State
University on this project. Below is a link to her website:
