Insertion mutation of the int-1 and int-2 loci by mouse mammary tumor virus in premalignant and malignant neoplasms from the GR mouse strain.

abstract：:The Sindbis virus minimal subgenomic mRNA promoter (spanning positions -19 to +5 relative to the subgenomic mRNA start site) is approximately three- to sixfold less active than the fully active -98 to +14 promoter region. We identified two elements flanking the -19 to +5 region which increase its transcription to leve...
