1 Connective tissue growth factor induction by lysophosphatidic acid requires transactivation of transforming growth factor type beta receptors and the JNK pathway. lysophosphatidic acid cellular communication network factor 2 Homo sapiens
2 We decided to evaluate the effect of LPA together with TGF-beta on CTGF expression. lysophosphatidic acid cellular communication network factor 2 Homo sapiens
3 We found that myoblasts treated with LPA and TGF-beta1 produced an additive effect on CTGF expression. lysophosphatidic acid cellular communication network factor 2 Homo sapiens
4 In the absence of TGF-beta, the induction of CTGF expression by LPA was abolished by a dominant negative form of the TGF-beta receptor type II (TGF-betaRII) and by the use of SB 431542, a specific inhibitor of the serine/threonine kinase activity of TGF-betaRI, suggesting that CTGF induction is dependent on LPA and requires active TGF-betaRs. lysophosphatidic acid cellular communication network factor 2 Homo sapiens
5 In the absence of TGF-beta, the induction of CTGF expression by LPA was abolished by a dominant negative form of the TGF-beta receptor type II (TGF-betaRII) and by the use of SB 431542, a specific inhibitor of the serine/threonine kinase activity of TGF-betaRI, suggesting that CTGF induction is dependent on LPA and requires active TGF-betaRs. lysophosphatidic acid cellular communication network factor 2 Homo sapiens
6 In the absence of TGF-beta, the induction of CTGF expression by LPA was abolished by a dominant negative form of the TGF-beta receptor type II (TGF-betaRII) and by the use of SB 431542, a specific inhibitor of the serine/threonine kinase activity of TGF-betaRI, suggesting that CTGF induction is dependent on LPA and requires active TGF-betaRs. lysophosphatidic acid cellular communication network factor 2 Homo sapiens
7 Finally, we demonstrated that CTGF induction in response to LPA requires the activation of JNK, but not ERK, signaling pathways. lysophosphatidic acid cellular communication network factor 2 Homo sapiens
