✦ Synopsis


A human cervical keratinocyte cell line, W 12, has been initiated from a low-grade cervical lesion histologically diagnosed as CIN I. This cell line has, to date, undergone over 300 generations in vitro with an average doubling time of 30 hr: an aneuploid karyotype has developed with progressive in vitro growth. WI2 contains HPV16 DNA present at approximately 100 copies and the state of the viral DNA over a number of passages has been examined. The HPV16 DNA is stably maintained at high copy number over several passages and restriction enzyme analysis together with electrophoresis of uncleaved viral DNA indicate that it is present predominantly as the episomal molecule. W12 cells exhibit a typical keratinocyte morphology and, when transplanted into the flank of the nude mouse, form an epithelial lesion with the histological features of CIN 1/11.

The retinoic-acid-receptor beta gene (RAR-beta) encodes a suspected tumor suppressor for several types of human carcinomas. RAR-beta transcription is induced by retinoic acid (RA) through retinoid receptors which bind as heterodimers of a RA-activated RA receptor (RAR) and a retinoid X receptor to t

## Abstract Clonal analysis has shown that the SW613‐S human colon‐carcinoma cell line is heterogeneous; some cell clones display a high level of amplification of the c‐__myc__ gene and are tumorigenic in nude mice, whereas others have a small number of copies of this gene and are non‐tumorigenic.
