MECP2 Knockout SK-N-SH Cell Line

The MECP2 Knockout SK-N-SH Cell Line is a genetically engineered human neuroblastoma cell line in which the MECP2 gene has been disrupted using CRISPR/Cas9-mediated genome editing. This knockout cell line provides a defined loss-of-function model for investigating MECP2-dependent transcriptional regulation and its role in neuronal biology. The product is supplied as a viable, adherent cell line suitable for expansion and cryopreservation, enabling consistent experimental replication across studies.

The parental SK-N-SH cell line was originally established from a bone marrow metastasis of neuroblastoma in a human female patient. It exhibits an adherent, neuronal-like morphology and retains features of catecholaminergic neuronal progenitors. SK-N-SH cells are widely used as a model system for studying neuronal differentiation, function, and plasticity, as they can be induced to differentiate into mature neuronal phenotypes under defined culture conditions. This background provides a relevant neuronal cellular context for examining the consequences of MECP2 loss.

MECP2 encodes a methyl-CpG-binding protein that functions as a transcriptional repressor by recruiting co-repressor complexes, including SIN3A and histone deacetylases (HDAC1/2), to methylated DNA. In neurons, MECP2 plays a critical role in activity-dependent gene regulation, downstream of signaling factors such as BDNF, CREB, CaMKII, PKA, and Akt. Phosphorylation by CaMKII triggers MECP2 release from chromatin, modulating expression of key neuronal targets like BDNF, DLX5, IGFBP3, SIRT1, and Mef2c. MECP2 also interacts with NCoR, SMRT, YB-1, HP1, and RNA splicing factors, linking DNA methylation to chromatin architecture, transcriptional elongation, and mRNA processing. Its regulatory network intersects with the mTOR pathway, cAMP signaling, and REST-mediated repression, underscoring its centrality in coordinating synaptic maturation and plasticity.

In the SK-N-SH neuroblastoma background, MECP2 disruption provides a physiologically relevant platform for dissecting the role of methylation-dependent gene silencing in neuronal progenitor cells and their differentiated derivatives. Because MECP2 is essential for normal neuronal maturation and synaptic function, this knockout cell line enables the study of how loss of this repressor alters gene expression programs, chromatin states, and cellular responses to neuronal activity cues. It serves as a powerful tool for modeling aspects of Rett syndrome, MECP2 duplication syndrome, and related autism spectrum disorders, where MECP2 dosage is critically perturbed.

Researchers can employ the MECP2 Knockout SK-N-SH Cell Line to investigate transcriptional dynamics using RNA-seq and ChIP-qPCR, assess DNA methylation patterns via bisulfite sequencing, and validate protein-level changes through Western blotting and immunofluorescence. Functional studies may include calcium imaging and electrophysiological recordings to evaluate neuronal activity and synaptic properties, as well as drug sensitivity assays to screen for pharmacological interventions that modulate downstream pathways. This product enables detailed mechanistic inquiries and therapeutic discovery efforts for neurodevelopmental disorders. For further information, please contact Ascent Research.
