| Research Abstract |
The goal of this investigation was to study the expression and regulation of β1,3-Glucuronosyltransferase-I (GlcAT-I), a key enzyme regulating GAG synthesis in cells of the intervertebral disc. There was a robust expression of GlcAT-I in the nucleus pulposus in vivo. We demonstrate that calcium regulates expressionof GlcAT-I, a critical enzyme required for GAG synthesis through TonEBP/NFAT5 and Cn-NFAT signaling pathways.
