Expression of histamine H_1 receptor gene in hepatocarcinoma of rats induced by dimethylamino-azobenzene / 中国药理学通报

ABSTRACT

AIM To study the mRNA expression of histamine H_1 receptor in hepatocarcinoma of rats. METHODS Dimethylamino-azobenzene (DAB) was used to induce hepatocarcinoma in rats. Semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR) was adopted to analyse the relative expression of histamine H_1 receptor. And the base sequence of its PCR product was detected. RESULTS The relative mRNA expression of histamine H_1 receptor was significantly decreased in hepatic carcinoma tissue, compared with that part far from cancer and control group (P
