The HDAC6 Knockout KYSE-30 Polyclonal Cells represent a CRISPR/Cas9-edited polyclonal knockout cell population derived from the human esophageal squamous cell carcinoma (ESCC) cell line KYSE-30, featuring targeted disruption of the HDAC6 gene. This loss-of-function model is generated using a non-clonal, polyclonal knockout format, ensuring a heterogeneous yet highly effective disruption of HDAC6 expression across the cell population. The product provides a powerful tool for studying the pleiotropic roles of HDAC6 in cancer cell biology without the constraints of single-cell clonal selection.
KYSE-30 is a well-characterized human ESCC cell line established from a well-differentiated tumor of the middle esophagus. These epithelial cells retain key molecular features of esophageal squamous cell carcinoma and are widely employed in oncogenic signaling studies, drug response profiling, and functional genomics. The genetic stability and tumorigenic properties of KYSE-30 make it an ideal host for investigating the impact of HDAC6 loss in esophageal cancer.
HDAC6 is a cytoplasmic deacetylase that primarily targets ??-tubulin and HSP90. By deacetylating ??-tubulin, HDAC6 regulates microtubule stability and dynamics, controlling cell migration and invasion. Its action on HSP90 modulates chaperone function and client protein stability. HDAC6 operates downstream of EGFR, TGF-??1, IL-6, SP1, and HIF1A, and influences downstream effectors including Cortactin, Peroxiredoxin-1, Tau, and ??-catenin. Through interactions with dynein, ubiquitin, VCP/p97, and Ubiquilin, HDAC6 participates in aggresome formation and autophagic clearance. This signaling network integrates pathways such as EGFR/AKT/ERK and TGF-??/SMAD2/3, with functional crosstalk to autophagy via Beclin1.
In the KYSE-30 ESCC context, HDAC6 disruption abrogates ??-tubulin deacetylation, leading to impaired microtubule stability and reduced cell motility, which is critical for metastasis. The concomitant loss of HSP90 deacetylation destabilizes HSP90 client proteins and sensitizes cells to proteotoxic stress and apoptosis. This knockout model thus mirrors key aspects of HDAC6 biology and can be used to dissect signaling through EGFR/AKT/ERK and TGF-??/SMAD2/3 pathways, as well as autophagy regulation involving Beclin1. The polyclonal nature preserves population-level heterogeneity, enhancing physiological relevance in functional assays.
These polyclonal knockout cells are specifically suited for esophageal cancer research, HDAC6 inhibitor screening, migration and invasion assays, and autophagy flux analyses. Researchers can employ Western blotting to confirm target knockout and downstream effects, immunofluorescence to assess microtubule acetylation, apoptosis assays to study drug sensitivity, and functional migration assays to evaluate metastatic potential. The model also facilitates co-culture studies and combinatorial drug testing in an ESCC background. For further details or customization, please contact Ascent Research.
