The EDIL3 Knockout A-549 Polyclonal Cells are a CRISPR/Cas9-edited polyclonal knockout cell population derived from the human A-549 lung adenocarcinoma cell line, generated for targeted disruption of the EDIL3 gene. This loss-of-function model, produced without clonal selection, provides a heterogeneous pool of edited alleles suitable for bulk functional analyses of EDIL3-dependent cellular processes.
A-549 cells serve as a classical alveolar type II-like lung adenocarcinoma model, extensively characterized for studies of epithelial biology, oncogenic transformation, and drug response. Their well-defined signaling networks and reproducible growth characteristics render them a dependable host for knockout generation, ensuring consistent experimental outcomes across replicate experiments.
Upon integrin engagement, EDIL3 promotes focal adhesion formation and activates FAK and Src, which phosphorylate downstream effectors including PI3K and the MAPK pathway. This leads to AKT and ERK1/2 phosphorylation, driving cell survival and proliferation. Additionally, EDIL3 enhances NF-??B activity, leading to MMP2/MMP9 expression and Bcl-2 upregulation. The gene is transcriptionally regulated by HIF-1?? under hypoxic conditions, and by inflammatory cytokines TNF-?? and IL-1??, as well as VEGF. EDIL3 also facilitates efferocytosis through phosphatidylserine recognition and interactions with BAI1 and TIM4.
In the A-549 adenocarcinoma context, EDIL3 loss impedes key oncogenic signals, making this model valuable for studying lung tumor cell adhesion, invasiveness, and survival. It enables the examination of EDIL3??s role in PI3K/AKT and MAPK/ERK pathway activation, and how its absence affects angiogenic factor secretion and inflammatory responses. This can uncover novel vulnerabilities in EDIL3-expressing lung cancers.
Researchers can employ these cells in cell adhesion assays on integrin ligands, transwell migration and invasion studies, and quantification of phosphorylated FAK by ELISA. Western blotting for phospho-AKT and phospho-ERK, immunofluorescence for integrin ??v??3 localization, and apoptosis detection by flow cytometry are also facilitated. Functional angiogenesis can be assessed via tube formation assays. These polyclonal knockout cells are ideal for drug sensitivity screening, functional genomics, and studies of efferocytosis and inflammation. For technical assistance, contact Ascent Research.
