Expression of MKK3 and MKK6 and their relative contribution to the activation of p38-MAPK isoforms in OA has not been reported. | |||||||||||||||
| |||||||||||||||
|
Transfection of human OA chondrocytes with MKK3 or MKK6-specific siRNAs knocked down the expression of target proteins and inhibited the IL-1? | |||||||||||||||
| |||||||||||||||
|
-induced activation of p38-MAPK (Figure 2b, c), but the inhibition of phosphorylation was more pronounced when the expression of MKK3 was knocked down compared to the knockdown of MKK6 (Figure 2b).

|
Expression and activation of MKK3 and MKK6 in human OA chondrocytes | |||||||||||||||
| |||||||||||||||
|
Human OA chondrocytes were transfected with human MKK3 or MKK6-specific siRNAs using On-Target SMART Pools (# L-00350900, L-00396700, Dharmacon RNA Technologies, Lafayette, CO, USA). | |||||||||||||||
| |||||||||||||||
|
Next, we investigated the effect of MKK3 or MKK6 knock down on the phosphorylation of p38-MAPK in response to stimulation with IL-1? | |||||||||||||||
| |||||||||||||||
|
We then used these antibodies to determine the expression and phosphorylation of MKK3 and MKK6 proteins in human OA chondrocytes. | |||||||||||||||
| |||||||||||||||
|
Immunoblots and transcriptional reporter assays using specific inhibitors, as well as expression of constitutively active forms of MEK1 and MKK3, showed that c-IAP2 induction by cAMP is regulated predominantly through ERK1/2 and p38 MAPK and suggested involvement of p90 ribosomal protein S6 kinase and mitogen and stress response kinase-1 as well. | |||||||||||||||
