title: Altered levels of histone H1(0) and DNA topoisomerase activity in the liver of the tumour-bearing rat.
abstract: Walker 256 carcinoma cells were injected subcutaneously into the dorsal region of rats. After 9 days of tumour growth increases were observed in liver mass and DNA content and in the incorporation of [3H]-thymidine into liver DNA. These changes were accompanied by a fall in the H1(0) fraction of liver histones and rises in both DNA topoisomerase I and II activities.
