Abstract
A process of producing mammalian tumor necrosis factors (TNF) and TNF-like polypeptides by culturing eukaryotic or prokaryotic hosts transformed with DNA sequences encoding those polypeptides. A process for purifying TNF-like polypeptides using an anion exchanger. The TNFs and TNF-like polypeptides produced by the processes of this invention, and compositions and methods utilizing those TNFs and TNF-like polypeptides, are useful in anticancer, antitumor and antimalarial therapies. They are also useful together with interferon therapy, chemotherapy in anticancer and antitumor therapies, and in combination with actinomycin D in the treatment of tumor-bearing mammals.
