Post-Transcriptional Regulation of Papillomavirus Gene Expression
نویسنده
چکیده
Papillomavirus genomes are transcribed as one large complex transcription unit with multiple promoters, two poly(A) sites (early and late), and considerable alternative splicing. As a result, there are multiple opportunities for post-transcriptional regulation of papillomavirus gene expression. Although this area has not been as extensively studied as transcriptional regulation, there are a few well documented examples of post-transcriptional regulatory elements which have been identified in the papillomaviruses. This review will focus on elements which work at levels up through translation, but will not include post-translational regulation.

Objective(s):OCT4 is a transcription factor required for pluripotency during early embryogenesis and the maintenance of identity of embryonic stem cells and pluripotent cells. Therefore, the effective expression regulation of this gene is highly critical. UTR regions are of great significance to gene regulation. In this study, we aimed to investigate the potential regulatory role played by 5´UT...

Drought stress is one of the most determinative factors of agriculture and plays a major role in limiting crop productivity. This limitation is going to rising through climate changes.

The root endophyti...

Background: Bispecific antibodies represent an important class of mAbs, with great therapeutic potentials due to their ability to target simultaneously two distinct epitopes. The generation of functional bispecific antibodies with the highest possible yields is particularly critical for the production of these compounds on industrial scales. Anti- CD3 × CD19 bsAb is a bispecific T-cell engager ...
