SK-LU-1 Cells

SK-LU-1 is a human lung adenocarcinoma cell line widely used in cancer research, particularly in studies focused on non-small cell lung cancer (NSCLC). As a cisplatin-sensitive cell line, SK-LU-1 is often employed in studies evaluating chemotherapy resistance, cancer cell cycle progression, and apoptosis mechanisms. One of the defining features of SK-LU-1 is its utility in assessing the cytotoxic effects of various anti-cancer compounds, including those that modulate the cell cycle or induce apoptosis through targeted therapies. For instance, certain 6-substituted imidazopyridine derivatives have been shown to induce G2/M phase arrest and apoptosis in SK-LU-1 cells, indicating that these compounds may inhibit cyclin-dependent kinases (CDKs) involved in cancer cell division. Additionally, SK-LU-1 cells have been used in studies exploring the immunomodulatory effects of agents like melatonin. In co-culture experiments with peripheral blood mononuclear cells (PBMCs), melatonin was shown to enhance the immune system's ability to induce apoptosis in SK-LU-1 cells. The treatment led to increased oxidative stress, reduced glutathione (GSH) levels, and cell cycle arrest at the G0/G1 phase, suggesting that melatonin may have potential as a supplementary treatment in NSCLC by boosting immune response and promoting cancer cell death. Overall, SK-LU-1 provides a robust in vitro model for studying lung adenocarcinoma and testing novel therapeutic agents, including those that target the cell cycle, induce apoptosis, or modulate immune responses. Its responsiveness to chemotherapeutic agents like cisplatin and the wide range of experimental data available make it an important tool in NSCLC research.
