Figure 3. Gene expression in MKK3−/− and MKK6−/− osteoclasts.
WT, MKK3−/− and MKK6−/− osteoclast RNA was isolated and subjected to qPCR using gene-specific primer probe sets (n = 3/group). Expression of NFATc1, cFos, Cathepsin K, OSCAR and MMP9 was significantly lower in MKK3−/− but not MKK6−/− cells, compared with WT. RANK expression was comparable in WT, MKK3−/− and MKK6−/− groups. *p<0.05.
