Urinary excretion of cyclic guanosine 3':5'-monophosphate and cyclic adenosine 3':5'-monophosphate in rats bearing transplantable liver and kidney tumors.
Cyclic guanosine 3':5'-monophosphate (cyclic GMP) and cyclic adenosine 3':5-monophosphate were measured in the urine of normal rats and those bearing transplantable liver and kidney tumors. The level of cyclic GMP ranged from 1.4 to 1.6 mumoles/g urinary creatinine in several strains of rats without tumors. Rats bearing Morris hepatomas 20, 21, 9618A and 9633F and kidney tumor MK2 had urine levels of cyclic GMP from 1.3 to 3.6 mumoles/g creatinine. Rats bearing the fast growing hepatomas 9618A2 and 3924A and Morris kidney tumor MK3 had urinary values of 5.6. 41.9, and 32.7 mumoles cyclic GMP per g creatinine, respectively. Urine levels of cyclic adenosine 3':5'-monophosphate ranged from 10.1 to 19.7 mumoles/g creatinine in all normal and tumor-bearing rats and were not significantly different in any of the groups examined.
