BOD1 Knockout HAP1 Polyclonal Cells provide a CRISPR/Cas9-edited polyclonal knockout cell population designed for the disruption of the BOD1 gene in a haploid cellular background. This loss-of-function model abolishes BOD1 expression, enabling researchers to dissect its role in chromosome biorientation and mitotic progression without clonal selection artifacts. The polyclonal format captures the heterogeneity of genetic edits inherent to CRISPR-based gene disruption, offering a physiologically relevant population-level response compared to monoclonal derivatives.
The parental HAP1 cell line is a near-haploid human cell line originally derived from the KBM-7 chronic myeloid leukemia (CML) line. Its haploid karyotype streamlines functional genomics, as single-copy gene disruption eliminates the confounding effects of diploid heterozygosity. HAP1 cells retain critical mitotic and checkpoint machinery, making them a robust system for studying the molecular mechanisms governing chromosome segregation and the consequences of mitotic defects in a leukemia-relevant context.
BOD1 is an essential regulator of chromosome biorientation, stabilized kinetochore-microtubule attachments, and proper chromosome alignment during mitosis. Its activity is regulated by CDK1 and Aurora B kinase, and it functions within a network that includes BUB1, BUBR1, PLK1, and BUB3. BOD1 disruption impairs the recruitment or function of downstream effectors such as BUB1, BUBR1, and CENP-E, leading to defective kinetochore-microtubule attachments, activation of the spindle assembly checkpoint, and ultimately chromosome missegregation and aneuploidy.
In the HAP1 model, BOD1 knockout recapitulates hallmarks of chromosomal instability syndromes and cancer-associated aneuploidy. The haploid background amplifies the phenotypic consequences of mitotic errors, providing a sensitive readout for spindle checkpoint defects and chromosome segregation failures. This system is particularly valuable for elucidating the molecular basis of CML and other hematologic malignancies, where aberrant cell division contributes to disease progression and drug resistance.
Researchers can employ these polyclonal knockout cells in a wide array of experimental workflows, including high-content immunofluorescence microscopy to visualize mitotic spindle morphology, live-cell imaging to track real-time chromosome dynamics, flow cytometry for cell cycle profiling, and Western blotting to assess mitotic protein expression. They are also well suited for aneuploidy assays and high-throughput screening of novel mitotic inhibitors.
