Abstract

Cyclic-AMP-dependent protein kinase activity was depressed in whole spleen as well as in isolated splenic lymphocytes from 3-methylcholanthrene (MCA), R3230 AdCa mammary adenocarcinoma, N-hydroxy-2-acetylaminofluorene, and 4-dimethylaminoazobenzene (DMAAB) tumor-bearing Fischer rats as compared to control animals. The magnitude of depression increased with the immunogenicity of the tumor. The depressed enzyme activity was the result of a reduced Vmax for adenosine 3',5'-monophosphate (cAMP)-stimulated histone phosphorylation.

摘要

与对照动物相比,来自患3-甲基胆蒽(MCA)、R3230 AdCa乳腺腺癌、N-羟基-2-乙酰氨基芴和4-二甲基氨基偶氮苯(DMAAB)肿瘤的Fischer大鼠的全脾以及分离的脾淋巴细胞中的环磷酸腺苷依赖性蛋白激酶活性降低。抑制程度随肿瘤的免疫原性增加而增加。酶活性降低是由于3',5'-单磷酸腺苷(cAMP)刺激的组蛋白磷酸化的Vmax降低所致。
