Project Diet effects on gallstone formation, liver pathology, plasma lipids, and pathogen-accelerated atherosclerosis in 8 obesity mutant mouse strains

All animals were fed a high-fat (15% fat) diet for 8 wks. Blood chemistry and cholesterol were measured. After sac, a pathology review of livers and gallbladders was conducted.

Study design: all mice subjected to an intervention; 1 cohort.
8 strains tested     female male     Test age: 15-19wks

Mice
Strain and animal info
Note
Mice were housed in a non-barrier facility during the acclimation and testing periods. Three pathogens were detected during this time: Pneumocystis, Pasturella, and Helicobacter. Pathogen-accelerated atherosclerosis was observed in these studies. These results are in contrast to a similar study conducted in a pathogen-free facility (Paigen2).

Similar data are available for 43 inbred strains also tested by these investigators; see Paigen1 (identical C57BL/6J and C57BLKS/J data are present in both data sets).

This project includes a collection of browsable liver pathology images.

Note
Please note: Low sample sizes (N < 5) are present. [View table]
Note
Some measurements were derived by MPD staff,
based on supplied data. [View list]
Note
Some measurements are not eligible for all-MPD pheno vs. pheno
correlations due to data characteristics or semantics [View list]
