Human tumour necrosis factor has about 30% homology in its amino acid sequence with lymphotoxin, a lymphokine that has similar biological properties. Recombinant tumour necrosis factor can be obtained by expression of its complementary DNA in Escherichia coli and induces the haemorrhagic necrosis of transplanted methylcholanthrene-induced sarcomas in syngeneic mice.
人肿瘤坏死因子的氨基酸序列与淋巴毒素有大约30%的同源性,淋巴毒素是一种具有相似生物学特性的淋巴因子。重组肿瘤坏死因子可通过在大肠杆菌中表达其互补DNA获得,并能诱导同基因小鼠体内移植的甲基胆蒽诱导肉瘤发生出血性坏死。
