HOXD9 Knockout HEK293T Polyclonal Cells are a CRISPR/Cas9-edited polyclonal population of HEK293T cells with disrupted HOXD9 expression. This format provides a genetically diverse loss-of-function model that avoids clonal selection bias, enabling the study of HOXD9??s average functional impact across a cell pool. HOXD9 is a homeobox transcription factor involved in developmental patterning and cell proliferation, making this knockout product suitable for initial phenotypic screening and mechanistic investigations.
The host cell line, HEK293T, is a human embryonic kidney line expressing SV40 large T-antigen, known for high transfection efficiency and robust protein expression. Widely used for gene editing, viral production, and recombinant protein studies, these adherent cells offer a genetically tractable and non-differentiating background. HEK293T cells are a standard platform for CRISPR-mediated knockout experiments due to their ease of culture and reliable performance in molecular and cellular assays.
HOXD9 is a homeodomain transcription factor that regulates limb and skeletal development, cell differentiation, and proliferation. It functions within signaling networks activated by retinoic acid receptors, FGF, Wnt/??-catenin, and TGF-?? pathways. HOXD9 transcriptionally controls genes involved in cell cycle and adhesion, including CDKN1A (p21), TP53, ITGB3 (integrin ??3), E-cadherin, and vimentin. Its activity is modulated by interactions with cofactors PBX1, MEIS1, and HDAC complexes. In developmental contexts, HOXD9 collaborates with FGF8, SHH, BMPs, and TBX5 to orchestrate limb bud outgrowth. In cancer, dysregulation of HOXD9 is associated with altered proliferation and migration through pathways such as Wnt/??-catenin and TGF-??, impacting cyclin D1 and integrin expression.
In HEK293T cells, disruption of HOXD9 likely impairs transcriptional programs governing proliferation and adhesion, potentially attenuating responses to retinoic acid, FGF, and Wnt signals. The polyclonal knockout model enables the study of HOXD9??s core regulatory functions without the confounding influences of tissue-specific differentiation. Altered expression of downstream targets like p21 and integrins can be monitored using standard biochemical assays, providing insights into the gene??s role in cell cycle and migration. This population is valuable for initial functional screening before generating clonal lines.
This polyclonal HOXD9 knockout cell pool supports diverse applications, including functional studies of limb development regulators, identification of HOXD9 transcriptional targets via ChIP-qPCR or RNA-seq, and drug screening for HOX pathway inhibitors. It is suitable for proliferation, adhesion, and migration assays, as well as reporter gene analyses of HOXD9 transcriptional activity. Standard protocols for Western blotting, RT-qPCR, and immunofluorescence can be applied to characterize the knockout phenotype. For further details, please contact Ascent Research.
