## Abstract The effect of human interferon on growth and fibronectin production in a range of cultured breast cancer cell lines has been investigated. The cell lines differ in their sensitivity to interferon's growth‐inhibitory effect as determined from growth curves, but the degree of sensitivity

✦ Synopsis
Abstract
Human lymphoblastoid interferon inhibited the growth in vitro of fibroblasts and epithelial cells from normal, hyperplastic and neoplastic human breast tissue. At an interferon concentration of 10^3^ international units (IU) per ml, the inhibitory effects on monolayer growth were completely reversible but the growth potential of cells at lower density in colony‐forming cultures was not completely recovered. Studies on the cell cycle distribution of interferon‐treated cells demonstrated that the growth‐inhibitory effect was not due to an effect on one specific phase of the cell cycle, but to a lengthening of all phases.

## Abstract In this paper we describe a model system for looking at the effects of human interferon, IFN, on an established human tumour. Highly purified human IFN derived from lymphoblastoid cells (HuIFNα‐Namalwa) strongly inhibited the growth of a human breast cancer growing as a xenograft in nud
Infection of freshly established malignant human tumor cells with the adeno-associated viruses AAV-2 or AAV-5 inhibits cell proliferation. Normal human fibroblasts are also affected, but appear to partially escape the inhibition. In cell cultures of permanent lines of human and rodent origin, cell n
Addition of ATP (>0.1 mM) to cultures of human breast cancer T47D cells resulted in an inhibition of cell proliferation. The inhibition was found to be specific for ATP, and dependent on its concentration. Growth inhibition continued for at least three days, although ATP and its hydrolysis products
