The MORC2 Knockout Raji Polyclonal Cells represent a CRISPR/Cas9-edited polyclonal knockout cell population designed for targeted disruption of the MORC2 gene in a Raji B lymphoblastoid background. This product provides a loss-of-function model system for investigating MORC2-dependent chromatin remodeling and DNA damage repair mechanisms. The polyclonal pool captures a spectrum of CRISPR/Cas9-mediated mutations within the cell population, enabling the study of heterogeneous gene disruption effects without clonal selection. Researchers can utilize these cells to interrogate MORC2??s role in transcriptional repression, lipogenesis regulation, and stress-associated signaling networks.
The Raji host cell line is an Epstein-Barr virus (EBV)-positive Burkitt’s lymphoma-derived B lymphocyte model, widely employed in B-cell malignancy studies, immunoglobulin production analyses, and antigen presentation research. Its transformed phenotype and robust growth characteristics make it suitable for high-throughput functional genomics and drug screening applications. Raji cells retain key features of B-cell biology, including surface marker expression and signaling competence, providing a physiologically relevant context for examining oncogenic pathways such as PI3K/AKT and WNT. This background is particularly useful for dissecting how MORC2 perturbations intersect with B-cell proliferation and survival programs.
MORC2 is a chromatin-remodeling enzyme that functions as a transcriptional repressor of lipogenic genes, including FASN and ACACA, while simultaneously facilitating DNA damage repair through interactions with BRCA1, RAD51, and the NuRD complex containing HDAC1 and HDAC2. Upstream, MORC2 is regulated by DNA damage signals transmitted via ATM and ATR kinases, as well as by PAK1 and histone deacetylases. Downstream targets encompass CDKN1A, a key cell cycle regulator, and additional effectors in the DNA damage response. Mechanistically, MORC2 integrates chromatin compaction with repair protein recruitment, and its disruption in Raji cells can alter gene expression profiles, chromatin states, and the balance between lipogenesis and stress adaptation.
In the Raji B-cell lymphoma context, MORC2 knockout may significantly impact cellular responses to genotoxic stress, metabolic rewiring, and proliferative capacity. The ablation of MORC2-mediated transcriptional repression could lead to upregulation of FASN-driven lipogenesis, potentially fueling membrane biosynthesis and oncogenic growth. Concurrently, impaired DNA repair via diminished BRCA1 and RAD51 activity may sensitize cells to DNA-damaging agents, offering a model to study chemoresistance mechanisms. By generating a polyclonal knockout population, this tool reflects the complexity of heterogeneous gene disruption, allowing for the assessment of population-level phenotypes such as clonal competition and adaptive signaling rewiring in B-cell lymphoma.
Typical research applications encompass cancer biology, DNA damage response profiling, B-cell lymphoma modeling, drug resistance screening, and functional genomic dissection of MORC2 pathways. Compatible assays include Western blotting, RT-qPCR, RNA-seq, chromatin immunoprecipitation (ChIP), immunofluorescence, flow cytometry, comet assay, metabolic assays for lipogenesis, and cell proliferation measurements. These cells enable mechanistic studies linking chromatin remodeling to oncogenic signaling, providing a platform for target validation and therapeutic discovery.
