Effects of TNF alone and Incombination with Antitumor Chemicals on Carcinosarcoma in vitro / 中国肿瘤生物治疗杂志

ABSTRACT

Objective: To investigate the effects of rhTNF alone and in combination with antitumor chemicals on Walker-256 cell line in vitro. Methods: the cytotoxic activity in vitro were be examined by MTT method and the flow cytometry(FCM) analysis and alteration of every phase of cell cycle for rhTNF or (and) Adriamycin(ADM) against Walker-256 cell line. Results: rhTNF had a strong activity of antitumor in vitro and good dose-effect relationship(r=0.9811). Compared with negative control group, the effect of rhTNF was significant (P
