We have compared the effects of alpha and recombinant gamma interferons (IFNs) on the growth of human lung cancer cell lines in vitro. There was a diversity of response amongst the lines studied, the most sensitive being COR-L23 (a large cell anaplastic carcinoma line) and POC (a small cell line). In these two lines, IFN-gamma was found to be more potent than IFN-alpha. During cell growth of line POC in the presence of IFN-gamma no significant shift in cell cycle distribution occurred. When lines COR-L23 and POC were grown as xenograft tumours in nude mice, daily injection of 4 X 10(5) units per mouse per day of IFN-gamma produced no discernible retardation of tumour growth.
我们比较了α干扰素和重组γ干扰素(IFN)对人肺癌细胞系体外生长的影响。在所研究的细胞系中存在反应差异,最敏感的是COR-L23(一种大细胞间变性癌系)和POC(一种小细胞系)。在这两个细胞系中,发现γ干扰素比α干扰素更有效。在γ干扰素存在的情况下POC细胞系生长过程中,细胞周期分布未发生明显变化。当COR-L23和POC细胞系作为异种移植肿瘤在裸鼠体内生长时,每天每只小鼠注射4×10⁵单位的γ干扰素未产生明显的肿瘤生长迟缓。
