2V6.11 Cells

2v6.11 cells were derived from the human embryonic kidney line HEK-293 in 2001. The 2V6.11 cell line is a valuable resource for studying the adenoviral E4 oncoprotein, particularly the E4 34K protein known to be involved in cellular genome maintenance and repair. 2V6.11 cells, obtained through transfection with the plasmid pVgRxR followed by pEKORF6, result in the inducible expression of the E4 34K protein, which is linked to the inhibition of cellular mechanisms that repair double strand-breaks in DNA. The 2V6.11 cell line demonstrated that the adenoviral proteins E4 34k and E1b 55k inhibit chromosomal DNA repair by disrupting non-homologous end joining (NHEJ) and destabilizing DNA repair proteins, extending their effect from extrachromosomal to cellular genomic DNA. The 2V6.11 inducible cell line, with their adherent epithelial morphology, are ideal for investigating the behavior and characteristics of kidney-derived epithelial cells, including their response to infections by human adenovirus 40. This versatile cell line, which can be detected by western blot, enables researchers to delve into the molecular mechanisms by which the adenovirus E4 oncoprotein inhibits repair processes, thus contributing to our understanding of adenovirus pathology and the potential for developing new therapeutic strategies.
