Li-7 Cells

The Li-7 cell line is a human hepatocellular carcinoma (HCC) cell line that is commonly used in cancer research, particularly in the study of liver cancer. Derived from a primary liver tumor, Li-7 cells exhibit the typical characteristics of HCC, including the ability to produce alpha-fetoprotein (AFP), a marker often elevated in liver cancer. These cells are also known for their genetic stability, which makes them a reliable model for long-term studies. Genomic analysis of Li-7 cells has revealed various chromosomal abnormalities that are characteristic of HCC, including gains in regions such as 5p, 8q, and 11q, and losses in 13q and 14q. These chromosomal changes are indicative of the complex genetic alterations that drive hepatocarcinogenesis. Specifically, the gain in 8q is associated with the amplification of the MYC oncogene, which plays a crucial role in cell cycle progression and proliferation, further emphasizing the utility of Li-7 cells in oncogenic pathway studies. Li-7 cells also serve as a valuable model for studying the molecular mechanisms underlying HCC, including the pathways involving key genes like TFDP1, CUL4A, and CDC16, which have been identified as targets of amplification in HCC. These genes are involved in cell cycle regulation and DNA repair, processes that are often dysregulated in cancer. Thus, the Li-7 cell line is instrumental in elucidating the molecular events that lead to the development and progression of liver cancer, providing insights that could guide therapeutic strategies.
