Isolated from highly inbred strains that had very high incidence of the tumours, after the discovery that the disease was transmitted by nursing mothers in milk. Endogenous provirus present in germ line of all inbred mice. Transcription of the provirus is regulated by a viral promoter that increases transcription in response to glucocorticoid hormones. May transform by proviral insertion activating the cellular int 1 oncogene (18 Nov 1997) |
