    Notes: Abstract Expression and localization of parathyroid hormone-related protein (PTHrP) in rat articular cartilage during fetal and postnatal periods were investigated by immunohistochemistry and in situ hybridization. PHTrP displayed distinct distribution and intensity of staining at different ages. In fetal (18-day-old) and young (3-week-old) rats, articular chondrocytes expressed abundant PTHrP throughout the entire thickness of cartilage. In contrast, in 60-week-old rats, PTHrP was expressed in a few articular chondrocytes of superficial and middle layers. Regulation of PTHrP and PTH/PTHrP receptor mRNA was also studied in cultured rat articular chondrocytes. Northern blot analysis revealed that both transforming growth factor-β (TGF-β), an important stimulator for chondrocyte proliferation and differentiation, and 10% fetal bovine serum (FBS) stimulated the expression of PTHrP mRNA with down-regulation of its receptor mRNA. In contrast, 12-O-tetradecanoylphorbol-13-acetate (TPA) down-regulated the expression of receptor without changes of PTHrP mRNA level. These results suggest that the changes in abundance and localization of PTHrP and its receptor may be directly involved in the cell growth and differentiation of articular cartilage.

    Notes: Abstract In order to determine whether there is a difference in the effect of the hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitor pravastatin on cholesterol synthesis between the morning and the evening, we studied the 24-h profile of mevalonate in plasma and urine in 11 subjects with heterozygous familial hypercholesterolaemia. In study 1, eight subjects with familial hypercholesterolaemia took pravastatin (20 mg) once in the morning, and another 20-mg dose in the evening after a 1-week wash-out period. In study 2, five subjects with familial hypercholesterolaemia took pravastatin (20 mg per day) in the morning on 3 consecutive days and on 3 days in the evening after a 1 day wash-out. Plasma mevalonate concentrations were reduced at 9 h and 5 h after pravastatin administration in the morning and the evening, respectively. Urinary mevalonate excretion was significantly reduced at 4–8 h after pravastatin administration in the morning (51 vs 19 nmol ⋅h−1) and at 4–16 h after pravastatin administration in the evening (56 vs 27 nmol ⋅h−1). Daily urinary mevalonate excretion was equally and significantly reduced by pravastatin in the morning or evening. In conclusion, we found that morning and evening administration of pravastatin caused equal reductions in plasma and urinary mevalonate concentrations.
