The BICC1 Knockout HeLa Polyclonal Cells are a CRISPR/Cas9-edited polyclonal knockout cell population derived from the HeLa cell line, providing a loss-of-function model for the BICC1 gene. This heterogeneous pool contains a mixture of cells with various editing events, enabling population-level analysis of BICC1 disruption. It serves as a robust tool for studying BICC1??s role in Wnt/??-catenin signaling regulation and cell migration without the influence of clonal artifacts.
HeLa cells are a human cervical adenocarcinoma epithelial cell line widely employed in biomedical research. Their well-characterized signaling networks, rapid proliferation, and relevance to cancer biology make them an ideal host for investigating BICC1 function. The cells exhibit active Wnt signaling and migratory properties, aligning with the pathway of interest.
BICC1 encodes an RNA-binding protein that negatively regulates Wnt/??-catenin signaling by controlling the translation of downstream targets. Under normal conditions, BICC1 suppresses DVL2 and PKD1 protein levels, thereby attenuating ??-catenin stabilization and transcriptional activity. The miR-17~92 cluster upstream represses BICC1 expression, forming a regulatory loop. Knockout of BICC1 lifts this translational control, leading to upregulation of DVL2 and PKD1 and subsequent hyperactivation of Wnt/??-catenin signaling via the Frizzled?CDVL2?CGSK3?¨C??-catenin axis. This dysregulation impacts planar cell polarity and cell migration programs.
In the HeLa context, BICC1 knockout offers a relevant model for cervical adenocarcinoma research, where Wnt pathway aberrations frequently occur. The polyclonal nature avoids single-clone bias, permitting robust assessment of BICC1??s impact on tumor cell migration and polarity. Furthermore, shared pathway components with ADPKD, including PKD1, extend the model??s utility to renal cystogenesis studies.
Researchers can employ this knockout model in Wnt/??-catenin luciferase reporter assays, Western blotting for DVL2, PKD1, and ??-catenin, and RT-qPCR for downstream targets like Axin2 and Cyclin D1. Migration and invasion assays quantify functional outcomes, while immunofluorescence for polarity markers reveals cellular asymmetry defects. Additional applications in cancer biology and kidney disease modeling are readily supported. For further inquiries, please contact Ascent Research.
