The CAV1 Knockout DLD-1 Polyclonal Cells constitute a CRISPR/Cas9-mediated polyclonal knockout cell population targeting the CAV1 gene in the human DLD-1 cell line. This product provides a loss-of-function model with disrupted expression of caveolin-1, the scaffolding protein encoded by CAV1. The polyclonal format represents a heterogeneous pool of edited cells, eliminating the need for single-cell cloning and enabling robust population-level analyses.
The host cell line DLD-1 is a well-characterized adherent epithelial model derived from a human colorectal adenocarcinoma classified as Dukes?? type C. DLD-1 cells are widely employed in cancer research for investigating tumorigenesis, metastatic progression, and drug sensitivity, particularly within the context of colorectal cancer. Their stable growth characteristics and relevance to human disease make them a suitable platform for gene perturbation studies.
CAV1 encodes caveolin-1, a principal structural component of caveolae that functions as a negative regulator of multiple signal transduction cascades. Mechanistically, caveolin-1 scaffolds and inhibits signaling molecules including SRC family kinases, ERK, and eNOS, thereby modulating pathways such as caveolar-mediated endocytosis, integrin signaling, TGF-beta/Smad, MAPK/ERK, PI3K-Akt, and Wnt. Upstream activators like TGF-beta, SRC, FAK, and ROS can influence CAV1 expression, while downstream effectors encompass EGFR, PDGFR, FAK, AKT, and Ras. Caveolin-1 also interacts with H-Ras, G proteins, and flotillin within caveolar domains.
In the DLD-1 colorectal adenocarcinoma background, disruption of CAV1 is expected to dismantle caveolar architecture and alleviate the tonic repression of oncogenic pathways. This deregulation can enhance cell proliferation, migration, and survival, mirroring aspects of CAV1 downregulation observed in aggressive colorectal tumors. Consequently, this knockout model enables dissection of caveolin-1-dependent regulatory mechanisms that govern epithelial tumor biology and metastatic behavior.
Researchers can employ this polyclonal CAV1 knockout model in a range of experimental contexts, including analyses of cancer cell signaling, caveolae biology, tumor microenvironment interactions, and drug resistance mechanisms. Representative assays include Western blotting for CAV1 and downstream targets (e.g., phospho-ERK, AKT), immunofluorescence for caveolar structure, transwell migration and invasion assays, proliferation assays, phospho-kinase arrays, co-immunoprecipitation of caveolin-1 complexes, and RT-qPCR for downstream targets. The model is particularly suited for investigating CAV1??s role in colorectal cancer metastasis. For further details or to request a quote, please contact Ascent Research.
