During early postnatal life, extensive changes in gene expression occur concomitantly in multiple major organs, indicating the existence of a common core developmental genetic program. This program includes hundreds of growth-promoting genes that are downregulated with age in liver, kidney, lung, an...

Temporal changes of gene expression from 1-wk- to 5-wk-old rat in kidney and lung, and the effect of prior growth inhibition on these genetic changes. In mammals, body growth is rapid in early life but decelerates with age. Somatic growth deceleration is caused by a gradual decline in cell prolifera...
ORGANISM(S): Rattus norvegicus 
To explore the mechanisms responsible for spatial and temporal regulation of the growth plate, we microdissected postnatal rat growth plates into their constituent zones and then used microarray analysis to characterize the changes in gene expression that occur as chondrocytes undergo spatially-asso...

Body size varies enormously among mammalian species. In small mammals, body growth is typically suppressed rapidly, within weeks, whereas in large mammals, growth is suppressed slowly, over years, allowing for a greater adult size. We recently reported evidence that body growth suppression in rodent...
ORGANISM(S): Ovis aries 
We used laser capture microdissection to isolate different zones of the articular cartilage from proximal tibiae of 1-week old mice, and used microarray to analyze global gene expression. Bioinformatic analysis corroborated previously known signaling pathways, such as Wnt and Bmp signaling, and impl...
