Introduction of human chromosome 11 via microcell transfer controls tumorigenic expression of HeLa cells

EMBO J. 1986 Dec 20;5(13):3461-6. doi: 10.1002/j.1460-2075.1986.tb04670.x.


Both tumorigenic segregant HeLa X human fibroblast hybrids and tumorigenic HeLa (D98/AH-2) cells can be converted to a non-tumorigenic state following introduction of a single copy of a fibroblast t(X;11) chromosome. The translocated chromosome contains approximately 95% of the 11 chromosome and the q26-qter portion of the X chromosome which contains the hypoxanthine guanine phosphoribosyl transferase (HPRT) gene. Introduction of a human X chromosome has no effect on tumorigenic expression. Suppression of tumorigenicity is relieved by selecting cells which have lost the t(X;11) chromosome by growth in medium containing 6-thioguanine (6-TG). Further, reintroduction of the t(X;11) chromosome into tumorigenic 6TGR cells again suppresses tumorigenicity. Thus, the introduction of a single copy of a human chromosome 11 is sufficient to completely suppress the tumorigenic phenotype of HeLa cells and is suggestive of the presence of tumor-suppressor gene(s) on this chromosome.
