Dengue virus (DENV) is a global threat where it is estimated that 390 million dengue infections occur annually. One of the challenges in DENV research is the production of a homogenous population of DENV particles. Furin is an important protease that cleaves the premembrane (prM) of immature DENV to pr peptide and M protein, forming mature DENV particles. However, inefficient furin-mediated cleavage produces heterogeneous mixtures of DENV virions. The goal of this project was to generate a stably transfected cell line expressing high levels of human furin to produce a more homogenous DENV population. Furin was cloned from U937-DC-SIGN cells and modified to include a V5 epitope tag. This gene was cloned into a commercially available pcDNA3.1(+) vector and transfected into Vero and HEK293T cells. Expression of furin-V5 protein in transfected HEK293T cells was confirmed by dot blot and western blot probed with an anti-V5-HRP antibody. The results from this project have contributed to the establishment of a cell line expressing furin and further selection is ongoing to generate the stable cell line.
