SNU-761

The SNU-761 cell line is a human hepatocellular carcinoma (HCC) model derived from an adult patient. As part of the Cancer Cell Line Encyclopedia (CCLE) and LIMORE (Liver Cancer Model Repository) initiatives, SNU-761 has been extensively characterized at multiple molecular levels. The cell line has been used to explore the genetic and transcriptomic heterogeneity typical of primary liver cancers, including those associated with hepatitis B virus (HBV) infection, which is prevalent in many East Asian HCC cases. Genomic profiling has revealed that LIMORE models such as SNU-761 often retain the mutational and copy number alteration landscapes of primary tumors, including alterations in key oncogenic drivers like TP53, CTNNB1, and FGF19.

SNU-761 and other liver cancer models in the LIMORE collection have undergone high-throughput drug sensitivity screening across a wide panel of chemotherapeutics and targeted agents. These pharmacogenomic datasets have allowed researchers to identify potential biomarkers predictive of response, such as gene-drug associations and synthetic lethalities relevant to common mutations in liver cancer. Furthermore, comparisons of transcriptomic and epigenetic data—such as DNA methylation and histone modification patterns—have helped classify SNU-761 within liver cancer subtypes and assess its functional attributes, including invasiveness and response to pathway-specific inhibitors. This extensive profiling makes SNU-761 a valuable model for studying HBV-related HCC and evaluating personalized therapeutic strategies.

37°C, 5% CO₂, humidified atmosphere.

1. Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit.

2. Upon receipt, either store the cryovial immediately at temperatures below -150°C to ensure the preservation of cellular integrity, or proceed to step 3 if immediate culturing is required.

3. For immediate culturing, swiftly thaw the vial by immersing it in a 37°C water bath with clean water and an antimicrobial agent, agitating gently for 40-60 seconds until a small ice clump remains.

4. Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening.

5. Carefully open the disinfected vial and transfer the cell suspension into a 15 ml centrifuge tube containing 8 ml of room-temperature culture medium, mixing gently.

6. Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium.

7. Gently resuspend the cell pellet in 10 ml of fresh culture medium. For adherent cells, divide the suspension between two T25 culture flasks; for suspension cultures, transfer all the medium into one T25 flask to promote effective cell interaction and growth.

8. Adhere to established subculture protocols for continued growth and maintenance of the cell line, ensuring reliable experimental outcomes.

Mycoplasma contamination is excluded using both PCR-based assays and luminescence-based mycoplasma detection methods.

To ensure there is no bacterial, fungal, or yeast contamination, cell cultures are subjected to daily visual inspections.

For long-term preservation, place vials in vapor-phase liquid nitrogen at about −150 to −196 °C. Storage at −80 °C is acceptable only as a short interim step before transfer to liquid nitrogen.

Cryopreserved cell lines are shipped on dry ice in validated, insulated packaging with sufficient refrigerant to maintain approximately −78 °C throughout transit. On receipt, inspect the container immediately and transfer vials without delay to appropriate storage.
