NCI-H226 Cells

The NCI-H226 cell line is derived from a human non-small cell lung carcinoma (NSCLC), specifically squamous cell carcinoma, and is a robust model for studying NSCLC pathogenesis and therapeutic responses. Characterized by its epithelial morphology, NCI-H226 has been utilized extensively in preclinical research focusing on squamous differentiation and apoptosis. This cell line has been pivotal in elucidating the mechanisms of squamous differentiation, particularly the formation of cross-linked envelopes (CLEs) and the role of transglutaminase activity, both of which are markers of terminal differentiation. One key finding associated with NCI-H226 is its response to agents such as suramin, which induces differentiation and apoptosis without necessarily inhibiting cell proliferation. Studies have demonstrated that suramin can stimulate involucrin expression, enhance cytosolic transglutaminase activity, and induce CLE formation in a protein synthesis-independent manner. These effects make NCI-H226 an ideal system for investigating therapeutic agents that exploit cellular differentiation pathways to combat resistant NSCLC. NCI-H226 has also been included in broader cancer research efforts, such as the NCI-60 drug screening program, providing insights into its pharmacological profiles and its utility in high-throughput drug screening. This cell lines genetic and phenotypic stability further solidify its importance in cancer research and therapeutic development.
