KLF6 Knockout HeLa Polyclonal Cells represent a CRISPR/Cas9-edited polyclonal knockout cell population derived from the HeLa cervical adenocarcinoma cell line (HPV18-positive). This product comprises a heterogeneous pool of cells carrying targeted disruptions of the KLF6 gene, generated via CRISPR/Cas9-mediated gene disruption without clonal isolation. It provides a robust loss-of-function model for investigating the tumor suppressor functions of the Kr??ppel-like factor 6 transcription factor in a well-characterized human epithelial cancer background.
HeLa cells are an immortalized epithelial line originally isolated from a cervical adenocarcinoma and are characterized by the presence of human papillomavirus 18 (HPV18) sequences. They are widely employed in cancer biology, signal transduction, and drug discovery due to their robust growth, ease of genetic manipulation, and extensive historical data. The cervical cancer origin and viral oncoprotein expression make HeLa cells particularly relevant for studying oncogenic pathways, tumor suppressor mechanisms, and cellular responses to therapeutic agents.
KLF6 is a zinc finger transcription factor that functions as a tumor suppressor by regulating cell proliferation, differentiation, and apoptosis. It is activated by upstream signals including TGF-??1, p53, Sp1, E2F1, TNF-??, and DNA damage. KLF6 transactivates key downstream targets such as CDKN1A (p21) and BAX, promoting cell cycle arrest and apoptosis, and also regulates CDH1 (E-cadherin), CCND1 (cyclin D1), TGFB1, BCL2, and MMP9. Mechanistically, KLF6 interacts with cofactors p53, Sp1, HDAC1, CREB-binding protein (CBP), and Smad3, integrating cues from TGF-??/Smad, p53, Wnt/??-catenin, MAPK/ERK, and JAK-STAT signaling pathways.
Disruption of KLF6 in HeLa cells impairs its tumor-suppressive transcriptional program, potentially leading to attenuated p21-mediated growth inhibition and reduced BAX-dependent apoptosis. In the HPV18-positive context, this knockout model may exhibit enhanced proliferation, survival, and altered responses to genotoxic stress and TGF-?? stimulation. It thus serves as a valuable tool for dissecting KLF6-dependent mechanisms in cervical carcinogenesis and for exploring cross-talk between viral oncoproteins and tumor suppressor networks.
Applications for this polyclonal knockout population span cancer biology, tumor suppressor characterization, and signal transduction research. Users can perform proliferation (MTT, BrdU) and apoptosis (Annexin V/PI) assays, cell cycle analysis by flow cytometry, TGF-?? stimulation and reporter assays, colony formation, and migration/invasion studies. Gene and protein expression analysis via RT-qPCR and Western blotting for KLF6, p21, BAX, and other pathway components enables detailed mechanistic investigation. The model is also suitable for drug response screening. For additional information, please contact Ascent Research.
