| | (1) A comparative study has been made on the induction of tryptophan pyrrolase by substrate and corticoids in liver tumor and the precancerous liver induced by 3'-MeDAB.(2) The liver tumor, contrary to normal liver, was inactive in response to both tryptophan and hydrocortisone for the induction of tryptophan pyrrolase, while the tissue adjacent to the tumor was active with respect to both substrate and hormonal induction.(3) A decrease in both substrate and hormonal induction was observed in the precancero... | | 本文对大鼠肝癌及癌前期肝内TP的底物诱导和激素诱导作了比较研究。在3′-MeDAB诱发的肝癌中,TP活性很低,且不因注射色氨酸或氢可地松而升高,而癌周组织则仍保留对底物和激素诱导的能力。喂3′-MeDAB 13天、28天、90天大鼠肝内TP的底物诱导效应都较对照组为低。急性注射3′-MeDAB25小时,以100毫克/100克体重的L-色氨酸进行诱导,TP的诱导效应亦较对照组为低。氢可地松诱导的结果与底物诱导的相似,无论在喂或急性注射3′-MeDAB的情况下,TP的诱导效应都受到抑制。但在相同条件下,非致癌物,2-MeDAB,对TP的底物诱导和激素诱导(慢性的或急性的实验)也有相似的作用。诱导后肝癌组织或喂偶氮染料的肝组织中都未发现有TP的抑制物或狗尿酸酶的激活物。微粒体及正铁血红素与上清液的加合实验表明:(1)肝癌微粒体几乎完全不具有激活TP的活力;癌前期(3′-MeDAB组)肝微粒体已部分失去此种生化功能,但2-MeDAB组微粒体则否。3′-MeDAB对肝微粒体中辅... | | 文摘来源 | | The normal liver mRNA wasisolated by oligo(dT)-cellulose chroma-tography of RNA extracted from liverpolysomes.
