miR-155 Inhibits Nucleus Pulposus Cells’ Degeneration through Targeting ERK 1/2

Figure 1

RT-PCR analysis of miR-155. miR-155 was highly expressed in normal nucleus pulposus cells and was lowly expressed in degenerative nucleus pulposus cells. Normal signal: data were analyzed using the comparison Ct () method to get the lg2 (microarray normalized signal). .
