The EEF1A2 Knockout A2780 Polyclonal Cells are a CRISPR/Cas9-edited polyclonal knockout population providing a heterogeneous pool with disrupted EEF1A2 function. The polyclonal format circumvents clonal selection artifacts, better reflecting biological variability of cancer populations and delivering a robust loss-of-function model.
The A2780 host cell line is an adherent epithelial line originally isolated from an untreated patient with ovarian carcinoma. It is widely employed as a model for high-grade serous ovarian cancer, recapitulating oncogenic signaling, apoptotic dysregulation, and chemotherapeutic drug sensitivity, particularly to cisplatin. Its well-characterized biology makes it an ideal background for EEF1A2 knockout studies.
EEF1A2 encodes a translation elongation factor that catalyzes GTP-dependent delivery of aminoacyl-tRNA to the ribosome, driving peptide chain elongation. Beyond protein synthesis, it inhibits p53-mediated apoptosis and organizes the actin cytoskeleton. Upstream, EEF1A2 is regulated by mTORC1/S6K signaling and transcriptionally activated by MYC and HIF1A. It forms complexes with the eEF1B components (EEF1B2, EEF1D, EEF1G) and interacts with actin, p53, and valyl-tRNA synthetase, thereby integrating growth and survival signals to coordinate translation, apoptosis suppression, and actin remodeling.
In A2780 cells, EEF1A2 overexpression contributes to enhanced translation, apoptotic resistance, and altered cell motility. Disruption of EEF1A2 in this polyclonal knockout enables dissection of mTOR/PI3K/AKT signaling networks and cisplatin sensitivity mechanisms. The model is particularly suited for investigating crosstalk between translational control and apoptosis in ovarian cancer, and the role of actin dynamics in metastatic potential.
This knockout pool is compatible with Western blotting and RT?qPCR for verifying EEF1A2 disruption, proliferation and caspase?3/7 activity assays for apoptosis assessment, cisplatin dose?response experiments to examine drug resistance, and migration/invasion assays to evaluate metastatic behavior. Immunofluorescence microscopy permits visualization of actin cytoskeletal reorganization, while polysome profiling reveals translation elongation defects. Researchers focused on ovarian cancer biology, translation regulation, or apoptosis will find this polyclonal knockout a powerful reagent for genetic perturbation studies.
