SLC25A37 Knockout HCT116 Cell Line

The choice depends on whether you are studying SLC25A37 (mitoferrin-1)'s role in mitochondrial iron import or its contributions to heme and iron-sulfur cluster biosynthesis. The Knockout line is the standard tool for asking whether mitoferrin-1 is required for delivering iron into the mitochondrial matrix — mitoferrin-1 is the principal mitochondrial iron importer in erythroid cells, with mitoferrin-2 (SLC25A28) playing a complementary role in non-erythroid tissues. Overexpression is useful for studying mitochondrial iron uptake mechanism or for rescue experiments. For mitochondrial iron biology research, the EDITGENE Mitoferrin-1 Knockout in HCT 116 enables study of mitochondrial iron import and downstream Fe-S cluster and heme biosynthesis. Mitoferrin-2 expression analysis is important given functional overlap in non-erythroid contexts. Rescue with wild-type or transport-deficient mitoferrin-1 is the standard specificity control. The knockout is relevant for studying erythroid maturation defects and iron metabolism in cancer biology.

Primary applications: • Mitochondrial iron uptake: ⁵⁵Fe-mitochondria isolation or mitochondrial iron sensor imaging to quantify mitoferrin-1-dependent iron import. • Heme biosynthesis: protoporphyrin IX accumulation and heme levels analysis to assess downstream consequences of disrupted mitochondrial iron supply. • Fe-S cluster assembly: aconitase activity and other Fe-S protein function assays as readouts of mitochondrial iron-sulfur cluster biogenesis. • Mitoferrin-2 compensation: SLC25A28 (mitoferrin-2) expression analysis given paralog overlap in non-erythroid contexts. EDITGENE recommends this model for researchers investigating mitochondrial iron biology, heme and Fe-S cluster biosynthesis, and erythroid maturation mechanisms.

Yes. Mitoferrin-1 rescue experiments require attention to mitochondrial inner membrane targeting: • Construct design: use a codon-modified SLC25A37 sequence with a small C-terminal tag (FLAG, HA). Mitoferrin-1 has the canonical SLC25 family 6-transmembrane architecture with mitochondrial targeting determinants. • Mitochondrial localization validation: confirm mitochondrial inner membrane localization by immunofluorescence co-staining with mitochondrial markers (TOM20, ATP5A) before functional assays. • Transport-deficient rescue: substrate-binding pocket mutations enable structure-function studies. • Functional readout: rescue should restore mitochondrial iron uptake, heme biosynthesis (protoporphyrin IX clearance), and Fe-S cluster-dependent enzyme activities. HCT 116 transduces efficiently with lentivirus and supports stable rescue line generation.
