SCC-9

SCC-9 is a human oral squamous cell carcinoma (OSCC) cell line commonly used in research focused on head and neck cancers, particularly in studying tumor progression, apoptosis, and treatment efficacy. OSCC is a prevalent form of head and neck cancer with a low 5-year survival rate, making cell lines like SCC-9 essential for understanding cancer biology and exploring potential therapeutic strategies. SCC-9 cells have been utilized in studies to assess the effects of various chemotherapeutic agents and natural compounds on oral cancer. For example, quercetin, a dietary flavonoid, has been shown to induce both necrosis and apoptosis in SCC-9 cells in a time- and dose-dependent manner. Quercetin?s antiproliferative effects were linked to the inhibition of thymidylate synthase, a key enzyme in DNA synthesis, leading to S-phase arrest in the cell cycle. The induction of necrosis was observed early, while prolonged exposure led to apoptosis through caspase-3 activation. Similarly, curcumin has been demonstrated to inhibit SCC-9 cell proliferation by regulating miR-9 expression, a microRNA associated with tumor suppression. Curcumin suppresses the Wnt/β-catenin signaling pathway, thereby reducing the levels of key oncogenic factors like cyclin D1. These findings highlight the relevance of SCC-9 cells in testing novel anticancer agents and unraveling the molecular mechanisms of OSCC development, particularly in targeting pathways like Wnt/β-catenin and assessing the role of apoptosis and cell cycle regulation.
