The KLF12 Knockout HAP1 Polyclonal Cells represent a CRISPR/Cas9-edited polyclonal knockout cell population derived from the near-haploid human HAP1 cell line. This product provides a pool of cells with targeted disruption of the KLF12 gene, enabling loss-of-function studies without the need for clonal isolation. The polyclonal format offers genetic diversity and robustness, making it suitable for screening applications and experiments where population-level responses are desired. Researchers should note that individual cells within the population may carry distinct editing outcomes, collectively achieving functional knockout of the target locus.
The HAP1 cell line originates from the KBM-7 chronic myeloid leukemia (CML) cell line and exhibits a near-haploid karyotype, simplifying genetic analysis by reducing gene copy-number complexity. These adherent, fibroblastoid cells retain hematopoietic progenitor features and are widely used in functional genomics, drug screening, and cell signaling research. The haploid nature facilitates the generation of knockout models with a single targeting event, enhancing efficiency and enabling straightforward genotype?Cphenotype correlations. HAP1 cells express key components of the TGF-?? and Wnt pathways, providing a physiologically relevant context for studying KLF12-mediated transcriptional repression.
KLF12 encodes a zinc-finger transcription factor that functions as a potent transcriptional repressor. Upon activation by upstream TGF-?? receptor signaling via SMAD2/3, KLF12 is recruited to target gene promoters where it assembles a corepressor complex containing CtBP1 and Sin3A-HDAC1/2. This complex mediates chromatin remodeling and histone deacetylation, leading to silencing of downstream targets such as TFAP2A (AP-2??), c-Myc, and CCND1 (Cyclin D1). Through this mechanism, KLF12 integrates signals from the TGF-?? and Wnt/??-catenin pathways to regulate cell proliferation, differentiation, and apoptosis. Additionally, KLF12 exhibits crosstalk with other KLF family members and contributes to tumor-suppressive networks in solid tumors.
In the HAP1 cellular background, disruption of KLF12 permits direct interrogation of its tumor-suppressive functions and transcriptional regulatory mechanisms. Given the origin of HAP1 from a hematopoietic malignancy, this model is particularly suited to investigate how KLF12-dependent gene silencing influences cell cycle progression, survival, and differentiation programs. The near-haploid genome ensures that any observed phenotypes can be attributed to loss of KLF12 function with high confidence, minimizing confounding effects from allelic variation. This cellular system enables detailed biochemical and cell biological analyses of KLF12-mediated repression in a genetically defined context, facilitating pathway dissection and downstream effector identification.
The KLF12 Knockout HAP1 Polyclonal Cells serve as a versatile model for cancer biology, developmental biology, and gene regulation research. Applications include Western blotting and RT-qPCR to verify KLF12 loss and monitor target genes like TFAP2A, c-Myc, and CCND1. ChIP-qPCR and dual-luciferase reporter assays facilitate investigation of promoter occupancy and transcriptional repression. Functional assays such as cell proliferation and immunofluorescence enable phenotypic analysis of proliferation, apoptosis, and localization. The knockout population aids in dissecting TGF-?? and Wnt pathway dynamics and drug responses. For further information, please contact Ascent Research.
