Inhibition of SV40 promoter activity by subfragments of 121-bp. a DNA sequences of four subfragments (I–IV) throughout 121-bp. b Reporter pGL3-Promoter Vector. Gray arrow indicates subfragment insertion site. c–f Influences of subfragments on SV40 promoter activity in four different cell lines. SV40 pGL3-Promoter Vector; I pGL3-SV40-I; II pGL3-SV40-II; III pGL3-SV40-III; IV pGL3-SV40-IV. Indicated P values are based on ANOVA: *P < 0.05; **P < 0.01; ***P < 0.001; Student’s t test: #P < 0.05, comparing to SV40 (N = 4–5, each in duplicate)
