The GORAB Knockout HeLa Polyclonal Cells consist of a CRISPR/Cas9-mediated polyclonal knockout population of HeLa cells, designed for loss-of-function studies of the GORAB gene. This heterogeneous pool represents multiple editing events, minimizing clonal effects and providing a robust experimental system. Knockout efficiency can be assessed by western blotting and Sanger sequencing, and the cells are supplied ready-to-use for downstream applications including imaging, biochemical, and functional assays.
The parental HeLa cell line is a human cervical epithelial adenocarcinoma model positive for HPV-18, extensively utilized in cancer biology research. Its epithelial origin and transformed state make it suitable for investigating Golgi organization and secretion in a malignancy-relevant context. HeLa cells also support standard cell biology techniques such as immunofluorescence microscopy and secretion assays, and are compatible with migration and invasion studies.
GORAB is a trans-Golgi network golgin that interacts with RAB6A and SCYL1 to coordinate retrograde COPI vesicle trafficking and Golgi ribbon integrity. Its membrane recruitment depends on ARF GTPases, placing it downstream of RAB6 activation. GORAB disruption leads to Golgi fragmentation, defective primary cilium assembly, and impaired secretion of matrix proteins, underscoring its role in linking trafficking to ciliogenesis and tissue organization.
In the HeLa background, GORAB knockout provides a model to study how Golgi dysfunction intersects with HPV-18-driven oncogenesis. Researchers can investigate impacts on secretory pathways, cell migration, and matrix remodeling, which are hallmarks of cervical carcinoma progression. The system also allows in vitro exploration of geroderma osteodysplasticum, a GORAB-linked skeletal dysplasia, even in a non-osteogenic lineage, by dissecting ciliary and trafficking defects.
Research applications include immunofluorescence for Golgi markers (GM130, TGN46), co-immunoprecipitation with RAB6, luciferase-based secretion assays, and serum-starvation-induced ciliogenesis assays. The cells are also suited for cell migration and invasion assays, facilitating correlations between Golgi integrity and cancer cell behavior. For further details, please contact Ascent Research.
