[Changes in the cyclic AMP level in the cells of murine sarcoma induced by monkey adenovirus SA7(C8) during tumor growth enhanced by lymphocytes from intact syngeneic mice].

Under consideration is the problem of changes in the cAMP level in sarcoma of mice CBA with routine and enhanced rate of growth. To this end the kinetics of sarcoma growth, induced by monkey adenovirus SA7 (C8), with common and stimulated by lymphocytes from intact syngeneic animals rates of growth was studied. Simultaneously, the kinetics of intracellular cAMP content in tumor cells was studied too. It was found that there is an inverse dependence between the cAMP content and the rate of sarcoma SA7 (C8) growth. Use of one type of tumor cells with the predetermined different rate of growth makes it possible to relate the changes in the content of intracellular tumor cell cAMP with changes being due to growth potentials.
