The BEND7 Knockout HEK293T Polyclonal Cells are a CRISPR/Cas9-edited polyclonal cell population with targeted disruption of the BEN domain-containing protein 7 (BEND7) gene. This loss-of-function model is generated in the widely used human embryonic kidney HEK293T cell line and provides a heterogeneous knockout pool ideal for functional studies without single-cell cloning. The CRISPR/Cas9-mediated gene disruption abolishes BEND7 expression, enabling investigation of its role in transcriptional regulation and chromatin biology.
HEK293T cells are human embryonic kidney epithelial cells that constitutively express the SV40 large T antigen, allowing high-level episomal replication of plasmids and efficient recombinant protein production. This adherent cell line is renowned for its excellent transfection efficiency and robust protein expression capabilities, making it a preferred host for gene functional analyses, viral vector packaging, and protein?Cprotein interaction studies. The renal epithelial origin offers a relevant cellular context for exploring kidney-related gene functions and regulatory mechanisms.
BEND7 belongs to the BEN domain protein family, which features a conserved DNA-binding BEN domain mediating chromatin interactions and transcriptional regulation. It likely recruits chromatin remodeling complexes and cooperates with other BEN domain proteins to modulate gene expression. Although specific upstream activators and downstream targets remain undefined, BEND7 probably influences nucleosome positioning and epigenetic marks. In the HEK293T knockout model, BEND7 disruption may alter chromatin states, perturb transcriptional networks, and change downstream gene expression, providing a tool to dissect these mechanisms.
In the HEK293T background, the BEND7 knockout offers a sensitized system to study chromatin remodeling and transcriptional control due to the high transcriptional activity driven by the SV40 large T antigen. This environment amplifies gene expression changes resulting from BEND7 loss, facilitating detection of phenotypic shifts. Comparative analyses between wild-type and polyclonal knockout populations can attribute specific regulatory effects to BEND7, shedding light on its function in an immortalized renal epithelial setting. The model thus bridges BEN domain biology with kidney cell physiology.
Researchers can employ these polyclonal knockout cells in diverse assays including RNA-seq for transcriptome-wide profiling, RT-qPCR for targeted gene expression analysis, ChIP-seq to map chromatin occupancy changes, and western blot to confirm BEND7 ablation. Functional validation using reporter gene assays enables testing of BEND7-responsive regulatory elements. These cells are an essential resource for functional genomics studies, chromatin biology research, and dissection of transcriptional regulatory networks.
