The CCDC127 Knockout SK-HEP-1 Polyclonal Cells product provides a CRISPR/Cas9-edited polyclonal knockout cell population in which the CCDC127 gene has been disrupted. This loss-of-function model is generated in the SK-HEP-1 human hepatic adenocarcinoma cell line and is supplied as a mixed population of edited cells, suitable for functional studies requiring heterogeneous gene knockout backgrounds. The disruption of CCDC127 eliminates its tumor-suppressive functions, allowing investigation of oncogenic signaling pathways.
The SK-HEP-1 cell line is an adherent epithelial line derived from the ascites fluid of a male patient with liver adenocarcinoma. Widely employed as a hepatocellular carcinoma (HCC) model, these cells exhibit characteristics of advanced liver cancer and are extensively used in studies of tumor biology, metastasis, and drug resistance. Their robust growth and well-characterized signaling networks make them an ideal platform for dissecting the molecular mechanisms of HCC progression.
CCDC127 functions as a tumor suppressor in hepatocellular carcinoma by negatively regulating Wnt/??-catenin and PI3K/AKT signaling. It interacts with ??-catenin, GSK3??, and Axin, preventing ??-catenin nuclear translocation and reducing TCF/LEF-mediated transcription. Consequently, the expression of oncogenic targets such as Cyclin D1, c-Myc, MMP2, and MMP9 is suppressed. Additionally, CCDC127 activity influences epithelial-mesenchymal transition (EMT) markers including E-cadherin, N-cadherin, and Vimentin. The gene is frequently silenced in HCC through promoter methylation and histone deacetylation, leading to unchecked activation of these downstream pathways.
In the SK-HEP-1 background, disruption of CCDC127 mimics the epigenetic silencing observed in clinical HCC specimens, thereby recreating a tumor-permissive cellular environment. This polyclonal knockout model recapitulates the loss of CCDC127-mediated growth suppression, leading to enhanced cell proliferation, migration, and invasiveness. The concomitant upregulation of Wnt/??-catenin and PI3K/AKT/mTOR signaling makes these cells valuable for investigating the molecular drivers of HCC aggressiveness and for testing therapeutic interventions targeting these pathways.
This polyclonal knockout product is well-suited for a wide range of functional analyses, including Western blotting and RT-qPCR to confirm downstream target modulation, CCK-8 and wound healing assays for proliferation and migration phenotyping, transwell invasion assays, and TOP/FOP flash reporter assays to quantify ??-catenin/TCF transcriptional activity. It also supports ChIP-qPCR for ??-catenin target occupancy, immunofluorescence localization of EMT markers, and transcriptome-wide RNA-seq profiling. Additionally, the model enables drug sensitivity screening with agents such as sorafenib to identify synergy between Wnt inhibition and standard HCC therapies.
