A high-resolution study of chromosome changes in a human prostatic carcinoma cell line (LNCaP).

A high-resolution study of chromosomal rearrangements in a human prostatic cancer cell line, LNCaP, has been performed. The cytogenetic analysis revealed a pseudodiploid karyotype and the presence of seven marker chromosomes resulting from five aberrational events. The analysis of four clones derived from the original line showed a near-tetraploid chromosome number and the presence of the same seven markers observed in the original line. This is the first complete description of karyotypic rearrangements in a prostatic cancer cell line.
