The KIF3A Knockout SK-HEP-1 Polyclonal Cells constitute a CRISPR/Cas9-engineered polyclonal loss-of-function model, achieved through targeted disruption of the KIF3A gene in the SK-HEP-1 human liver adenocarcinoma cell line. Offered as a polyclonal population, this product incorporates a diverse array of edited clones, ensuring reproducible phenotypic effects while mitigating clone-specific biases. This format is particularly well-suited for studies requiring population-level readouts of KIF3A-dependent processes.
The parental SK-HEP-1 cell line is a well-established model of human hepatocellular carcinoma, exhibiting epithelial morphology and prominent tumorigenic, migratory, and invasive characteristics. Its robust adherent growth and amenability to genetic manipulation have established it as a preferred host for generating gene knockouts aimed at dissecting molecular mechanisms driving liver cancer progression.
KIF3A encodes a motor subunit of the heterotrimeric kinesin-II complex, which powers anterograde transport of intraflagellar transport (IFT) particles and associated cargo along axonemal microtubules. Together with KIF3B and the adaptor protein KAP3, KIF3A mediates the ciliary delivery of essential signaling molecules, including Smoothened (SMO) in the Hedgehog pathway and ??-catenin in the Wnt pathway. Its expression is transcriptionally regulated by the ciliogenic factors RFX3 and FOXJ1, which act downstream of Hedgehog and Wnt ligands. Consequently, KIF3A disruption ablates ciliary trafficking, leading to impaired activation of GLI transcription factors and attenuation of Wnt/??-catenin signaling.
In the SK-HEP-1 hepatocellular carcinoma context, knockout of KIF3A provides a targeted system to interrogate the contribution of primary cilia and ciliary signaling to liver cancer cell behavior. By blocking ciliogenesis and disrupting Hedgehog and Wnt pathway activity, this model allows detailed analysis of how ciliary function influences proliferation, migration, and invasion??processes frequently dysregulated in hepatocellular carcinoma and associated with poor prognosis.
Typical experimental workflows include western blotting to confirm KIF3A ablation, RT-qPCR to assess downstream gene expression changes (e.g., GLI1, AXIN2), and immunofluorescence staining for ciliary markers such as acetylated ??-tubulin. Functional assays like Transwell migration/invasion and Hedgehog luciferase reporter assays are readily applicable to quantify phenotypic consequences. Researchers studying ciliary signaling in liver cancer will find this polyclonal knockout population a valuable and versatile tool. For additional information, please contact Ascent Research.
