Background & Aim: A lack of efficient gene-delivery carriers has always been the biggest challenge in gene therapy. Polyethylenimine (PEI) and poly (L-lysine) (PLL) are the most studied non-viral gene carriers. The purpose of this study is to prepare new nano-carriers, by conjugating these two polymers via 10 carbon linkers (10-bromodecanoic acid), in order to take advantage of them and compens...
The enhancer element of hepatitis B virus (HBV) regulates the transcription of all HBV mRNA, including the pregenomic mRNA used during replication. This pregenomic mRNA is transcribed from the core gene promoter which is located 500 bp downstream from the HBV enhancer element. To examine the effect of the HBV enhancer on the activity of the core gene promoter, we constructed various plasmids co...
The core promoter, which is generally defined as the region to which RNA Polymerase II is recruited to initiate transcription, plays a pivotal role in the regulation of gene expression. The core promoter consists of different combinations of several short DNA sequences, termed core promoter elements or motifs, which confer specific functional properties to each promoter. Earlier studies that ex...
