Human Gastric Cancer Cell Lines

Description

MKN-1 is a human gastric adenosquamous carcinoma cell line derived from a metastatic lymph node site of a 72-year-old male patient. This cell line exhibits a point mutation in the p53 gene at exon 5, resulting in amino acid replacements.. Gastric cancer accounts for approximately 1.5% of all newly diagnosed cancers, with 26,500 new cases and 11,130 deaths annually in the USA. Although gastric adenosquamous carcinoma is rare, with an incidence of less than 1%, it presents a more aggressive nature and poor prognosis compared to other types of gastric cancer. MKN-1 cells exhibit epithelial-like morphology and grow adherently under standard conditions. The cell line is cryopreserved for high viability and performance. MKN-1 cells also express tumor markers such as carcinoembryonic antigen (CEA). These cells are widely used for studies on gastric cancer pathogenesis, drug screening, and metastasis mechanisms.

Application

  • Due to its rarity, human gastric adenosquamous carcinoma has limited clinical treatment options. The utilization of MKN-1 in the scientific reports might unravel the cell proliferative properties of gastric carcinomas.MKN-1 revealed E-cadherin silencing via promoter CpG hypermethylation.MKN-1 can also used to discover inhibitory effects on tumor invasion. For example, eupatilin and exogenous RUNX3 may inhibit gastric cancer proliferation in MKN-1.

Frequently Asked Questions

  • How do I maintain the morphology of MKN-1 cells?

    Morphology: MKN-1 cells are epithelial in nature and should appear as adherent, polygonal cells. They should form a monolayer without significant clumping or detachment.

    Monitoring: Regularly observe cells under a microscope to ensure they retain their characteristic morphology. Abnormalities in shape or detachment may indicate issues with culture conditions.

  • How do I manage cell doubling time?

    Expected Doubling Time: MKN-1 cells typically have a doubling time of 24-36 hours under optimal conditions.

    Troubleshooting Slow Growth
    Nutrient Depletion: Ensure medium is changed every 2-3 days.
    Cell Density: Avoid over-confluency. Split cells when they reach 70-80% confluence.
    Contamination: Regularly check for microbial contamination.
    Medium Quality: Use high-quality FBS and RPMI 1640 medium. Ensure they are not expired or contaminated.
    Incubator Conditions: Confirm stable temperature and CO₂ levels in the incubator.

  • How do I assess the health and viability of MKN-1 cells?

    Viability Assays: Use trypan blue exclusion or MTT assay to determine cell viability.
    Morphological Assessment: Regularly observe under a microscope for normal morphology.
    Growth Curves: Plot cell growth over time to ensure consistent doubling time and healthy proliferation rates.
