WebMar 5, 2007 · A cryptic promoter in the PVX vector was discovered with RT-PCR. The promoter activity was studied with Northern blots and Real-time RT-PCR. Conclusion It is important to recognize the homologous promoter sequences in the vector when a virus is developed as an expression vector. WebApr 20, 2005 · Our results showed that cryptic promoter activity is present in the pim-1 5′-UTR sequence although we found that it is very difficult to disprove the presence of IRES. We found that DNA sequence corresponding to the pim-1 5′-UTR could regulate the expression of Pim-1.
