The KIAA0586 Knockout NCI-H1975 Polyclonal Cells are a CRISPR/Cas9-edited polyclonal knockout cell population originating from the NCI-H1975 non-small cell lung adenocarcinoma cell line. This loss-of-function model is designed for investigating the role of KIAA0586 in primary cilium assembly and associated pathways. The polyclonal nature enables study of heterogeneous gene disruption within a cancer cell context, offering a relevant system for functional genomics and drug discovery.
The NCI-H1975 cell line, derived from a lung adenocarcinoma patient, is a well-established model for non-small cell lung cancer (NSCLC). These adherent epithelial cells carry an activating EGFR mutation and are widely used to study oncogenic signaling, tumor biology, and therapeutic sensitivity. The lung cancer background provides a clinically pertinent setting to examine KIAA0586 function in adenocarcinoma pathology.
KIAA0586 encodes a centrosomal/centriolar satellite protein essential for primary cilium biogenesis. It interacts with PCM1, CEP290, and BBS proteins to regulate ciliary assembly, which is critical for Hedgehog (Hh) signal transduction. Within the primary cilium, Hh pathway components including Smoothened and SUFU control the activation of GLI transcription factors. KIAA0586 loss disrupts ciliogenesis, thereby attenuating Hh signaling and reducing expression of downstream targets like GLI1 and PTCH1. The gene is regulated by RFX transcription factors, tying it to a network controlling ciliary gene expression.
Primary cilia and Hh signaling are implicated in NSCLC progression, making this knockout model valuable for dissecting cilia-dependent tumorigenic mechanisms. Aberrant Hh pathway activity contributes to tumor growth, metastasis, and drug resistance. By disrupting KIAA0586, one can assess how ciliary dysfunction impacts these processes in lung adenocarcinoma, potentially uncovering novel therapeutic targets.
These polyclonal knockout cells are suitable for diverse experimental approaches, such as immunofluorescence with acetylated tubulin to evaluate ciliogenesis, western blotting for Hh pathway components, and RT-qPCR for GLI1 target gene quantification. Migration and invasion assays can further explore the role of KIAA0586 in lung cancer cell behavior. For additional information or custom inquiries, please contact Ascent Research.
