1 To understand the role of this cAMP-dependent PDE regulation in the potentiation of the mitogenic response to IGF-I, thymidine incorporation into DNA in response to IGF-I and TSH was measured in the absence or presence of PDE inhibitors. Thymidine insulin-like growth factor 1 Rattus norvegicus
2 To understand the role of this cAMP-dependent PDE regulation in the potentiation of the mitogenic response to IGF-I, thymidine incorporation into DNA in response to IGF-I and TSH was measured in the absence or presence of PDE inhibitors. Thymidine insulin-like growth factor 1 Rattus norvegicus
3 When IGF-I was used alone, both IBMX and RO 20-1724 potentiated IGF-I-stimulated thymidine incorporation. Thymidine insulin-like growth factor 1 Rattus norvegicus
4 However, when IGF-I and TSH at high concentrations were used in combination, these PDE inhibitors blocked thymidine incorporation into DNA. Thymidine insulin-like growth factor 1 Rattus norvegicus
