2553385-4	1989	Stimulatory effects on erythropoietin response are observed with the addition of compounds affecting the cAMP level such as forskolin, phosphodiesterase inhibitor and cholera toxin only in the presence of erythropoietin.	Cyclic AMP	105-109	erythropoietin	Mus musculus	23-37

2553385-5	1989	cAMP analogues themselves show no stimulatory effect on TSA8 cells, nor does erythropoietin increase cAMP level in the cells.	Cyclic AMP	101-105	erythropoietin	Mus musculus	77-91	
2553385-6	1989	Thus, it is suggested that cAMP does not act as a direct second messenger for signal transduction through erythropoietin receptors, but as a stimulator of the erythropoietin receptor pathway and/or as a second messenger in combination with the receptor pathway.	Cyclic AMP	27-31	erythropoietin	Mus musculus	106-120
