The HOMEZ Knockout HeLa Polyclonal Cells product consists of a CRISPR/Cas9-edited polyclonal knockout cell population derived from the HeLa human cervical adenocarcinoma cell line, designed to disrupt the HOMEZ gene. This genetically heterogeneous pool harbors a spectrum of editing events at the target locus, leading to loss of HOMEZ function across the population without selection for isogenic clones. The polyclonal format provides a robust model for studying HOMEZ-dependent processes while preserving cellular heterogeneity, making it suitable for population-level functional assays.
HeLa cells, originally isolated from a cervical adenocarcinoma, are an immortalized epithelial line that constitutively expresses the HPV-18 E6 and E7 oncoproteins. These viral factors inactivate the tumor suppressors p53 and pRb, respectively, creating a permissive background for unregulated cell cycle progression. This widely used cell line serves as a core model in cancer biology, drug discovery, and virology due to its stable growth characteristics, well-characterized genome, and extensive literature base.
HOMEZ encodes a homeodomain leucine zipper transcription factor with roles in development and hematopoiesis. Upstream regulation may involve Wnt and Notch pathways, but direct activators are unknown. HOMEZ dimerizes with other homeodomain and leucine zipper proteins, and likely recruits co-regulators and chromatin remodeling complexes to control gene expression. Its downstream targets remain elusive but are thought to encompass genes controlling proliferation and differentiation.
In the HeLa cervical cancer context, where key tumor suppressor pathways are compromised, ablation of HOMEZ offers a unique opportunity to dissect its role in malignancy. Given the gene??s potential involvement in hematopoiesis and transcriptional reprogramming, this knockout model can help elucidate how HOMEZ contributes to oncogenic transcriptional networks that drive cervical adenocarcinoma progression. Moreover, the HPV-18-positive background may reveal interplay between viral oncoproteins and HOMEZ-mediated gene regulation.
This knockout product is suitable for diverse downstream applications including functional genomics screens, mechanistic studies of HOMEZ-dependent transcription, and evaluation of candidate therapeutic targets. Typical experiments employ Western blotting to assess protein expression, RT-qPCR for mRNA quantification, ChIP-qPCR for DNA-binding analyses, and RNA-seq for transcriptome profiling. Cellular phenotypes can be measured through proliferation, colony formation, and immunofluorescence assays. For additional support or custom inquiries, please contact Ascent Research.
