abstract = {Genetic variation is a primary determinant of phenotypic
diversity. In laboratory mice, genetic variation can be a
serious experimental confounder, and thus minimized through
inbreeding. However, generalizations of results obtained
with inbred strains must be made with caution, especially
when working with complex phenotypes and disease models.
Here we compared behavioral characteristics of C57Bl/6-the
strain most widely used in biomedical research-with those of
129S4. In contrast to 129S4, C57Bl/6 demonstrated high
within-strain and intra-litter behavioral hyperactivity.
Although high consistency would be advantageous, the
majority of disease models and transgenic tools are in
C57Bl/6. We recently established six Cre driver lines and
two Cre effector lines in 129S4. To augment this collection,
we genetically engineered a Cre line to study astrocytes in
129S4. It was validated with two Cre effector lines: calcium
indicator gCaMP5g-tdTomato and RiboTag-a tool widely used to
study cell type-specific translatomes. These reporters are
in different genomic loci, and in both the Cre was
functional and astrocyte-specific. We found that calcium
signals lasted longer and had a higher amplitude in cortical
compared to hippocampal astrocytes, genes linked to a single
neurodegenerative disease have highly divergent expression
patterns, and that ribosome proteins are non-uniformly
expressed across brain regions and cell types.},
