KATO-III Cells

The KATO-III cell line is a human gastric carcinoma model derived from the metastatic site of a poorly differentiated adenocarcinoma. These cells are widely utilized in research focused on gastric cancer, particularly for studying the molecular mechanisms driving tumor progression, drug resistance, and metastasis. The KATO-III cells exhibit an aneuploid karyotype, characterized by multiple chromosomal abnormalities, which contributes to their aggressive cancer phenotype. They are notably p53 deficient, a feature often associated with increased tumorigenicity and altered responses to chemotherapy, making them a valuable tool for investigating the role of p53 in gastric cancer. KATO-III cells grow in suspension and display a rounded morphology. They possess a high capacity for proliferation, making them suitable for various in vitro applications, including drug screening and cytotoxicity assays. These cells are also used in studies of cell signaling pathways, as their aberrant signaling is a hallmark of gastric cancer pathogenesis. Researchers often utilize KATO-III cells to explore the efficacy of novel therapeutic agents, particularly those targeting HER2, EGFR, and other relevant oncogenic pathways. This cell line is essential for advancing our understanding of gastric cancer biology and for developing targeted therapies aimed at improving patient outcomes.
