The HOXD9 Knockout HeLa Polyclonal Cells are a CRISPR/Cas9-edited polyclonal knockout cell population derived from HeLa cells, with targeted disruption of the HOXD9 gene. This loss-of-function model enables investigation of HOXD9-dependent transcriptional programs in a human epithelial cell background. The polyclonal format captures heterogeneous editing events across the population, providing a robust tool for studying gene function without clonal selection artifacts.
HeLa cells are an immortalized epithelial cell line originally isolated from cervical adenocarcinoma. They serve as a widely utilized model for cervical cancer research, offering well-characterized growth properties, high transfection efficiency, and compatibility with diverse functional assays. The HeLa background provides a relevant context for exploring HOXD9??s role in cervical carcinogenesis, given the gene??s implication in anterior-posterior patterning and tumor progression.
HOXD9 encodes a homeodomain transcription factor that operates within the HOX gene regulatory network, integrating signals such as retinoic acid, FGF, SHH, and WNT to orchestrate developmental gene expression. It forms heterodimeric complexes with PBX1 and MEIS1, and cooperates with PREP1 to regulate downstream targets including other HOX genes and cell adhesion molecules. Knockout of HOXD9 disrupts these transcriptional complexes and impairs differentiation and proliferation programs, providing a platform to dissect retinoic acid and WNT-dependent signaling. Representative pathway components affected by HOXD9 loss include retinoic acid receptors and HOXD9-PBX/MEIS transcriptional assemblies that control target gene expression.
In the HeLa context, HOXD9 knockout likely alters gene networks governing epithelial differentiation and malignancy. Given its role in limb development and cervical cancer, this model enables correlation of molecular changes with phenotypic outcomes such as altered migration, invasion, and colony formation. The disruption of HOXD9 expression in HeLa cells provides a controlled system to evaluate how anterior-posterior patterning cues intersect with oncogenic pathways, potentially revealing vulnerabilities in cervical and colorectal cancer models.
This knockout product supports diverse experimental workflows, including western blotting for protein expression analysis, RT-qPCR and RNA-seq for transcriptome profiling, and ChIP-qPCR to assess transcription factor occupancy at target loci. Functional studies can employ immunofluorescence, migration and invasion assays, and colony formation assays to characterize phenotypes associated with HOXD9 loss. The model is particularly suited for dissecting HOX gene regulatory networks, Wnt signaling, and retinoic acid signaling in cancer biology and gene regulation.
