The EIF5A2 Knockout Huh-7 Polyclonal Cells product provides a CRISPR/Cas9-edited polyclonal knockout cell population with targeted disruption of the EIF5A2 gene in the Huh-7 human hepatocellular carcinoma cell line. This polyclonal pool contains a heterogeneous mixture of edited alleles, enabling robust loss-of-function studies without clonal selection biases. The polyclonal format preserves cellular heterogeneity and is particularly suitable for screening applications where population-level phenotypes are assessed. By generating a gene disruption model, these cells facilitate investigation of EIF5A2-dependent functions in liver cancer biology.
The Huh-7 cell line is a well-differentiated hepatocellular carcinoma originally derived from a 57-year-old Japanese male and exhibits epithelial morphology with integrated hepatitis B virus genome sequences. These cells are widely utilized in hepatic metabolism research, drug toxicity screening, and liver cancer studies owing to their retention of key hepatocyte functions and tumorigenic properties. The Huh-7 model provides a clinically relevant context for exploring molecular mechanisms in hepatocellular carcinoma, including oncogenic signaling and translational control.
EIF5A2 encodes a translation elongation factor that promotes peptide bond formation and resolves ribosome stalling on polyproline motifs, a function essential for efficient synthesis of proteins containing such sequences. EIF5A2 activity strictly depends on hypusination, a post-translational modification catalyzed by deoxyhypusine synthase (DHPS) and deoxyhypusine hydroxylase (DOHH) utilizing spermidine as a substrate. EIF5A2 is transcriptionally upregulated by MYC and activated downstream of mTOR signaling, linking nutrient-sensing pathways to translational output. In its activated form, EIF5A2 interacts with the ribosome and the exportin XPO4, facilitating the translation of specific oncogenic mRNAs and driving cell cycle progression, migration, and invasion in cancer cells.
In the Huh-7 hepatocellular carcinoma context, EIF5A2 is frequently overexpressed and contributes to aggressive tumor behavior, including enhanced proliferation and metastatic potential. This knockout model enables dissection of EIF5A2-dependent translation programs and their role in hepatocarcinogenesis. By eliminating EIF5A2 function, researchers can assess its impact on polyproline-rich protein synthesis, mTOR-driven growth, and spermidine-hypusination axis activity in a liver cancer cell line. The model also provides a platform for evaluating the dependency of hepatocellular carcinoma cells on EIF5A2-mediated oncogenic signaling and for identifying compensatory pathways.
Typical applications include analyzing translational control mechanisms using polysome profiling, assessing cell proliferation via MTT assays, and investigating migration and invasion through Transwell assays. Western blotting and RT-qPCR can confirm knockout efficiency and downstream target expression changes. These cells are valuable for drug sensitivity studies and synthetic lethality screens, identifying compounds that selectively target EIF5A2-deficient cancer cells. Apoptosis assays further enable exploration of cell death pathways engaged upon EIF5A2 loss. For more information or to request a quote, please contact Ascent Research.
