ABSTRACT
Objective To investigate the gene expression changes in normal and degeneration lumbar intervertebral disc in humans, providing information for clinical. Methods The PCR products of 4096 human genes were spotted onto a kind of chemical-material-coated-glass slides. The total RNAs were isolated from the tissues. Both the mRNAs from the degeneration and normal lumbar intervertebral disc in humans were reversely transcribed to the cDNAs, which used as the hybridization probes with the incorporations of fluorescent dUTP. The mixed probes were then hybridized to the cDNA microarray. After high-stringent washing, the cDNA microarray was scanned for the fluorescent signals and analyzed with computer image analysis. Results Among the 4096 targets,there were 706 genes whose expression levels differed between the degeneration and normal lumbar intervertebral disc in all cases,comprising 298 up-regulated and 358 down-regulated ones. Conclusion DNA microarray technology is an effective technique in screening for differently expressed genes between the degeneration and normal lumbar intervertebral disc. Cell apoptosis plays an important role in the process of lumbar intervertebral disc degeneration.
