Abstract:
:The formation of cyclic AMP was studied in normal liver, subcutaneous hepatomas derived from MH1C1 cells, and premalignant liver and primary hepatomas induced by the carcinogens 2-acetylaminofluorene (AAF) and 4-dimethylamino-azobenzene (DAB). While only very slight effects of prostaglandins (PG) were seen in slices of normal liver, all the hepatomas responded strongly to PGE1 and PGE2. The hepatomas also had increase PGE1-sensitive adenylate-cyclase activity. PGF1alpha and PGF2alpha did not increase the cAMP level significantly either in the liver or in the hepatomas. During AAF carcinogenesis the response to PGE1 increased slightly during the carcinogen feeding, and was greatly elevated only in the fully developed hepatomas. This is in contrast to the increase in adrenalin response seen during carcinogenesis, which starts much earlier, and reaches a peak value within 8--10 weeks. It is concluded that various hepatomas have elevated responsiveness to PGE1 and PGE2 as well as to adrenalin, but the course of change in the tissues' ability to respond to these agents during carcinogenesis is very different.
