NFIA Knockout THLE-2 Cell Line

The choice depends on whether you are studying NFIA (nuclear factor I A)'s role as a transcription factor in glial cell development and hepatocyte differentiation or modeling NFIA-related haploinsufficiency syndrome (with intellectual disability and urinary tract anomalies). The Knockout line is the standard tool for asking whether NFIA is required for these processes — NFIA binds palindromic TTGGC sequences as homodimers or heterodimers with other NFI family members, regulating gene expression in CNS development, hepatocyte biology, and other contexts. Overexpression is useful for studying NFIA in heterologous expression contexts. For hepatocyte and developmental research, the EDITGENE NFIA Knockout in THLE-2 is relevant — THLE-2 is a human hepatocyte cell line (SV40-immortalized normal liver epithelial), providing a human hepatic context for NFIA function studies. NFIB, NFIC, NFIX paralog expression analysis aids interpretation given functional overlap. Rescue with wild-type NFIA is the standard specificity control. The knockout is valuable for studying hepatocyte differentiation and NFIA-related developmental disorders.

Primary applications: • Hepatocyte gene expression: liver-specific gene expression analysis in NFIA-null hepatocyte context. • NFI binding site occupancy: ChIP-seq for NFIA binding (palindromic TTGGC sequences) to characterize the transcriptional program. • Heterologous CNS development studies: in neural-relevant contexts, characterization of NFIA's roles in astrocyte and oligodendrocyte specification. • NFIA syndrome modeling: rescue with patient-derived NFIA variants for genotype-function studies of intellectual disability and urinary tract anomalies. EDITGENE recommends this model for researchers investigating NFIA-dependent gene expression and NFIA-related developmental biology.

Yes. NFIA rescue experiments require attention to transcription factor architecture: • Construct design: use a codon-modified NFIA sequence with a small C-terminal tag (FLAG, HA). NFIA has N-terminal DNA-binding/dimerization (DBD-DD) domain and C-terminal transactivation region — preserve both. • DNA-binding-deficient rescue: DBD mutations disrupt TTGGC binding and serve as the standard specificity control. • NFI family partnership: NFIB, NFIC, NFIX expression analysis aids interpretation given heterodimer formation. • Functional readout: rescue should restore NFI target gene expression and hepatocyte-relevant transcriptional programs. THLE-2 is an SV40-immortalized normal human liver epithelial cell line — transduction with lentivirus is supported but may require optimization compared to standard transformed cell lines.
