The DYNLT3 Knockout HeLa Polyclonal Cells are a polyclonal cell population generated by CRISPR/Cas9-mediated disruption of the DYNLT3 gene in HeLa cells. This loss-of-function model enables investigation of DYNLT3, a dynein light chain involved in intracellular transport, mitotic spindle assembly, and apoptotic signaling, within a widely used human cervical cancer cell background. The polyclonal format ensures a heterogeneous gene knockout, reflecting natural variation in editing outcomes.
HeLa cells are an HPV18-positive immortalized epithelial cell line derived from cervical adenocarcinoma. They provide a robust platform for studying cancer cell biology, cell cycle control, and cytoskeletal dynamics, making them ideal for examining the functional roles of DYNLT3 in processes often dysregulated in malignancy.
DYNLT3 facilitates cargo binding and regulates cytoplasmic dynein motor activity. It interacts with core dynein subunits DYNC1H1 and DYNC1I1, the dynactin subunit DCTN1, and mitotic regulators Ndel1 and Lis1. DYNLT3 also binds Bcl-2 and Bim, linking dynein function to apoptosis. Upstream, its expression is regulated by E2F transcription factors and CDK1, while downstream it influences spindle assembly factors and apoptotic effectors. Consequently, DYNLT3 knockout disrupts intracellular trafficking, impairs mitotic spindle organization, and alters apoptotic responsiveness, providing a comprehensive loss-of-function model for dissecting these interconnected pathways.
In HeLa cells, DYNLT3 depletion is expected to compromise mitotic fidelity, leading to chromosome segregation errors and cell cycle delays, given the reliance of these rapidly dividing cancer cells on intact spindle machinery. Moreover, disruption of DYNLT3?CBcl-2 interactions may sensitize cells to apoptotic stimuli, offering a system to explore vulnerabilities in cervical cancer and to evaluate therapeutic strategies targeting dynein-dependent processes.
This knockout model is suitable for a variety of assays, including western blotting, immunofluorescence, flow cytometry for cell cycle and apoptosis analysis, and co-immunoprecipitation to assess protein interactions. Live-cell imaging of intracellular transport and motility assays further enable functional studies. Applications span dynein biology, mitotic regulation, and cancer cell research, supporting both mechanistic investigations and drug discovery. For further details, please contact Ascent Research.
