I use recombinant inbred (RI) mice and microarrays to study the several brain-related genetic problems. RI mice are an excellent resource for these studies and allow us to examine multiple types of data in a reference population. In addition to using the currently available RI strains, we have recently developed 45 additional BXD RI strains using two advanced intercross lines between C57BL/6 and DBA/2 mice as progenitors. In combination with the previously developed BXD strains this is the largest RI strain set in existence.
Many problems can be efficiently addressed using RI mice. One of these questions is the mechanism of genetic control over brain architecture. In order to study this issue we have collected extensive neuroanatomical and gene expression data in the brains of BXD strains. Because all animals are isogenic, we can collect data of the same and differing types from multiple animals and meaningfully relate each data set. This allows us to determine, for instance, whether steady state expression of a gene is related to an observed phenotype, for instance an aspect of brain architecture or a behavioral difference between strains.
Another fascinating problem that we are able to address with RI lines is the modulation of transcriptional control in response to environmental influences. Using the LXS and BXD RI strains we are examining the modulation of transcriptional control in response to alcohol, stress, and the combination of alcohol and stress treatments. By examining modulatory changes in response to these conditions, we hope to gain insight into the molecular substrates underlying differences in ethanol and stress responses?a question thought to be very important in understanding human alcoholism.
