A) GUSB enzyme activity in marrow (normalized to wild-type BL/6J) in 15-week male mice (n=3–5/group). B) Immunoblot of GUSB, HPSE, and KL expression in marrow from 15-week female wild-type C57BL/6J and partial loss-of-function C3H/HeJ mice, and 15-week male hetero- (+/mps) and homozygous (mps/mps) GUSB deficient mice (representative of n=3 biological replicate blots). C) Aglycone curcumin levels 20 minutes after IP curcumin administration (100 mg/kg) to 15-week female BL/6J, female HeJ mice and male mps/mps mice (n=3–5/group), expressed as % of total curcumin in serum vs. marrow suspensions. There were no significant differences in GUSB activity or aglycone curcumin content based on sex (data not shown). ****p < 0.0001 vs C57BL/6J. nd = not detectable
