FANCC Knockout HAP1 Cell Line

The choice depends on whether you are studying FANCC's role as a core Fanconi anemia (FA) complex member or modeling Fanconi anemia complementation group C disease. The Knockout line is the standard tool for asking whether FANCC is required for these processes — FANCC is one of nine core FA proteins (FANCA, FANCB, FANCC, FANCE, FANCF, FANCG, FANCL, FANCM, FANCT, plus FAAP-100 and FAAP-20) that form the FA core complex; this complex monoubiquitinates FANCD2 and FANCI in response to DNA interstrand crosslinks (ICLs), recruiting downstream FA-related proteins for ICL repair. Overexpression is useful for studying FANCC in heterologous expression contexts. For DNA repair and Fanconi anemia research, the EDITGENE FANCC Knockout in HAP1 is highly informative — FANCC mutations cause Fanconi anemia complementation group C (~10% FA cases), characterized by bone marrow failure, congenital abnormalities, and cancer predisposition. Rescue with wild-type or patient-derived mutant FANCC (e.g., IVS4+4 A>T splicing mutation common in Ashkenazi Jewish population) enables disease genotype-function studies. The knockout is valuable for studying interstrand crosslink repair, mitomycin C/cisplatin/cyclophosphamide sensitivity, and emerging FA-related cancer treatment strategies.

Primary applications: • FA core complex assembly: co-immunoprecipitation of FA core proteins in FANCC-null cells. • FANCD2/FANCI monoubiquitination: anti-FANCD2 and anti-FANCI Western blot analysis to assess upper band (monoubiquitinated FANCD2-L and FANCI-L) following ICL stress. • Mitomycin C/cisplatin sensitivity: cytotoxicity assays given FA pathway's role in interstrand crosslink repair. • FA modeling: rescue with patient-derived FANCC mutations (IVS4+4 A>T common Ashkenazi mutation, R548X, others) for genotype-function studies. EDITGENE recommends this model for researchers investigating Fanconi anemia mechanisms, interstrand crosslink repair, and DNA crosslinker chemotherapy sensitivity.

Yes. FANCC rescue experiments are well-established for FA pathway research: • Construct design: use a codon-modified FANCC sequence with a small C-terminal tag (FLAG, HA). FANCC interacts with FANCE in the FA core complex — preserve all elements. • FA mutation rescue: patient-derived FANCC mutations enable disease genotype-function studies — IVS4+4 A>T splicing mutation is common in Ashkenazi Jewish FA-C patients. • Complex assembly: rescue interpretation considers other FA core proteins (FANCA, FANCB, FANCE, FANCF, FANCG, FANCL, FANCM) expression. • Functional readout: rescue should restore FANCD2/FANCI monoubiquitination upon ICL stress and rescue mitomycin C/cisplatin sensitivity. HAP1-specific considerations: • Diploidization: HAP1 cells gradually diploidize during extended culture — confirm ploidy by flow cytometry at the time of phenotypic assay. • Integration site sensitivity: position effects on transgene expression are more pronounced in near-haploid backgrounds; generating multiple independent rescue clones is strongly recommended. • Transduction efficiency: HAP1 transduces with lentivirus at moderate efficiency — increase MOI compared to standard immortalized lines.
