Transcriptionally Active Regions Are the Preferred Targets for Chromosomal HPV Integration in Cervical Carcinogenesis
Integration of human papillomavirus (HPV) into the host genome is regarded as a determining event in cervical carcinogenesis. However, the exact mechanism for integration, and the role of integration in stimulating cancer progression, is not fully characterized. Although integration sites are reported to appear randomly distributed over all chromosomes, fragile sites, translocation break points...
متن کاملRetroviruses as genetic tools to isolate transcriptionally active chromosomal regions.
By exploiting the ability of retroviruses to move genes into random sites of mammalian genomes and by exploiting some features of their replication, retrovirus vectors have been developed that select for instances in which the virus integrates into expressed genes. Since integrated proviruses tag transcriptionally active sites, the vectors provide a means to identify and isolate promoters activ...
متن کاملTetraploidy and chromosomal instability are early events during cervical carcinogenesis.
Chromosomal instability as manifested by increases in aneuploidy and structural chromosome aberrations is believed to play a critical role in the intermediate to late stages in the development of cervical malignancies. The current study was designed to determine the role of tetraploidy in the formation of aneuploidy and ascertain the occurrence of these alterations during the earlier stages of ...
متن کاملConjugating plasmids are preferred targets for Tn7.
Most transposons display target site selectivity, inserting preferentially into sites that contain particular features. The bacterial transposon Tn7 possesses the unusual ability to recognize two different classes of target sites. Tn7 inserts into these classes of target sites through two transposition pathways mediated by different combinations of the five Tn7-encoded transposition proteins. I...
متن کاملThe transcriptionally active regions in the genome of Bacillus subtilis
The majority of all genes have so far been identified and annotated systematically through in silico gene finding. Here we report the finding of 3662 strand-specific transcriptionally active regions (TARs) in the genome of Bacillus subtilis by the use of tiling arrays. We have measured the genome-wide expression during mid-exponential growth on rich (LB) and minimal (M9) medium. The identified ...
