Biglycan (Bgn) is a small leucine-rich proteoglycan (SLRP) that is enriched in bone and other skeletal connective tissues and is responsible, in part, for the regulation of postnatal skeletal growth (Bianco, 1990). Mice lacking Bgn display reduced skeletal development and a lower peak bone mass that leads to age-dependent osteopenia (Xu, 1998). We hypothesized that mechanical loading could reverse the skeletal phenotype of Bgn knockout mice. To test this hypothesis, we determined the effects of treadmill running on the geometric, mechanical and mineral properties of Bgn deficient mice bones. After sacrifice, femora and tibiae were tested in 4 point bending and cross-sectional geometric properties and bone mineral parameters were measured. Exercise was able to partially reverse the skeletal phenotype of the Bgn knockouts by increasing both the geometric and mechanical properties of the tibiae to values equal to or greater than those of wild type control mice.

AbstractBackground and AimWDR13 - a WD repeat protein, is abundant in pancreas, liver, ovary and testis. Absence of this protein in mice has been seen to be associated with pancreatic β-cell proliferation, hyperinsulinemia and age dependent mild obesity. Previously, we have reported that the absence of WDR13 in diabetic Leprdb/db mice helps in amelioration of fatty liver phenotype along with diabetes and systemic inflammation. This intrigued us to study direct liver injury and hepatic regeneration in Wdr13−/0 mice using hepatotoxin CCl4.MethodsMice were injected with CCl4 twice a week for 8 consecutive weeks. Controls were injected with vehicle (olive oil) similarly. After the last injection, mice were given a 10-days of recovery period and then sacrificed for physiological and molecular analyses.ResultsIn the present study we report slower hepatic regeneration in Wdr13−/0 mice as compared to their wild type littermates after CCl4 administration. Interestingly, during the regeneration phase, hepatic hypertriglyceridemia was observed in Wdr13−/0 mice. Further analyses revealed an upregulation of PPAR pathway in the liver of CCl4-administered Wdr13−/0 mice, causing de novo lipogenesis.ConclusionsThe slower hepatic regeneration observed in CCl4 administered Wdr13−/0 mice, may be linked to liver hypertriglyceridemia because of activation of PPAR pathway.
