Figure 7.

The normalized signal intensity of genes involved in glycosaminoglycan degradation, pyrimidine metabolism and pyrimidine biosynthesis. The signal intensity for each functional gene was the average of the total signal intensity from all replicates. All data were presented as mean±s.e. *P<0.05. G-4-sulfohydrolase, N-acetyl-D-galactosamine-4-sulfate 4-sulfohydrolase (involved in chondroitin sulfate biosynthesis); G-6-sulfohydrolase, N-acetyl-D-glucosamine-6-sulfate 6-sulfohydrolase (involved in keratan sulfate biosynthesis); H-N-acetylhexosaminohydrolase, β-N-acetyl-D-hexosaminide N-acetylhexosaminohydrolase (involved in keratan sulfate biosynthesis).
