The HDAC10 Knockout HeLa Polyclonal Cells are a CRISPR/Cas9-edited polyclonal knockout cell population derived from HeLa cells, designed to disrupt the HDAC10 gene. This gene-edited model enables loss-of-function studies of histone deacetylase 10 (HDAC10) in a well-characterized human cervical adenocarcinoma epithelial line. The polyclonal format provides a heterogeneous pool of edited cells, each carrying CRISPR-mediated disruptions at the HDAC10 locus, facilitating robust functional genomics and drug discovery applications without clonal selection artifacts.
The host HeLa cell line is an HPV18-positive cervical adenocarcinoma model with an aneuploid, immortalized phenotype. HeLa cells are extensively used in cancer research, gene expression analysis, and transfection studies due to their robust growth and ease of manipulation. This established background allows researchers to investigate HDAC10-dependent processes in a relevant epithelial tumor context, with direct applicability to mechanistic studies in oncology.
HDAC10 functions as a histone deacetylase that modulates chromatin structure and gene expression by removing acetyl groups from histones H3 and H4, as well as from non-histone proteins such as HSP70, STAT3, ATG7, and Beclin-1. Its activity is regulated by upstream signals including IFN-??, STAT1, IRF1, and c-Myc, and it operates within multiprotein complexes containing HDAC3, NCOR1, and SMRT (NCOR2). A critical mechanistic role of HDAC10 is the promotion of autophagy through deacetylation of HSP70, which facilitates autophagic flux and cell survival under stress. This positions HDAC10 at the intersection of epigenetic regulation and cellular quality control pathways.
In HeLa cells, HDAC10 knockout provides a powerful platform to dissect its contributions to cancer biology, particularly in autophagy-dependent tumor progression and therapy resistance. The model is also relevant for studying inflammatory disorders and neurodegenerative processes, given HDAC10??s involvement in NF-??B and interferon signaling pathways. By eliminating HDAC10 activity, researchers can interrogate its role in modulating immune responses and stress adaptation, leveraging the HeLa background??s established signaling networks.
Typical research applications include autophagy flux assays using LC3 puncta immunofluorescence and flow cytometry, investigation of HDAC10-interacting partners via co-immunoprecipitation, transcriptomic profiling by RNA-seq, and cell viability or drug sensitivity screens for HDAC10 inhibitor development. The knockout cells are suitable for Western blotting and RT-qPCR to confirm target disruption, and for functional assays examining STAT1/IRF1-mediated interferon responses. This product serves as an essential tool for advanced molecular and cellular biology studies. For further information, please contact Ascent Research.
