Abstract

In order to identify chromosomes that carry putative tumor-suppressor genes for the various phenotypes of Kirsten sarcoma virus-transformed NIH/3T3 (DT) cells, we performed microcell-mediated chromosome transfer into DT cells. We first isolated mouse A9 clones, containing a single human chromosome 1, 11 or 12 tagged with pSV2-neo plasmid DNA. Then, chromosome 1, 11 or 12 was transferred from the A9 clones into DT cells by microcell fusion. The growth rate, colony-forming ability in soft agar and tumorigenicity of the DT cells were controlled by chromosome 1, but not by chromosome 11 or 12, indicating that normal human chromosome 1 carries a putative tumor-suppressor gene(s) that affects various transformed phenotypes of DT cells.
