SLC2A1 Knockout Cell Line (HEK293)

The choice depends on whether you are studying SLC2A1 (GLUT1)'s role as the principal ubiquitous glucose transporter or modeling GLUT1 deficiency syndrome (De Vivo disease). The Knockout line is the standard tool for asking whether GLUT1 is required for glucose uptake — GLUT1 is the principal glucose transporter in many cell types and the blood-brain barrier, essential for cerebral glucose supply. Overexpression is useful for studying GLUT1 trafficking and regulation or for testing GLUT1-targeted compounds (BAY-876, STF-31). Important consideration: GLUT1 is essential for most cells given its role in basal glucose uptake — complete knockout may significantly impair viability and proliferation in glucose-dependent contexts. Characterize growth phenotypes and consider supplementation with alternative carbon sources for extended culture. The EDITGENE Knockout in HEK293 is highly informative as the standard mechanistic platform for GLUT1 biology. Rescue with wild-type or De Vivo disease-associated mutant GLUT1 enables genotype-function correlation studies. The knockout serves as a critical specificity control for GLUT1 inhibitor pharmacology.

Primary applications: • Glucose uptake assays: ³H-2-deoxyglucose uptake to quantify GLUT1-dependent glucose transport in the absence of SLC2A1. • De Vivo disease modeling: rescue with patient-derived SLC2A1 mutations (e.g., R126H, R333W, common haploinsufficiency variants) for genotype-function studies of GLUT1 deficiency syndrome. • GLUT1 inhibitor specificity: critical genetic control for BAY-876, STF-31, WZB117, and other GLUT1-targeted compounds in cancer drug development. • Compensatory transport: GLUT3 and other GLUT expression analysis to characterize compensation in GLUT1-null cells. EDITGENE recommends this model for researchers investigating GLUT1 biology, GLUT1 deficiency syndrome, and GLUT1-targeted therapeutic development. Characterize viability/growth phenotypes given GLUT1's essential role in basal glucose uptake.

Yes, with viability and essentiality considerations: • Construct design: use a codon-modified SLC2A1 sequence with a small C-terminal tag (FLAG, HA). GLUT1 has 12 transmembrane domains — preserve plasma membrane targeting determinants. • Viability rescue: GLUT1 essentiality may require initiating rescue concurrently with or before knockout phenotype characterization; inducible (Tet-On) rescue systems are particularly useful. • Disease mutation rescue: De Vivo disease-associated mutations (R126H, R333W, R223P, others) enable comprehensive disease genotype-function studies. • Inhibitor specificity rescue: BAY-876-resistant or sensitivity-restored GLUT1 variants enable testing of GLUT1 inhibitor on-target activity. • Functional readout: rescue should restore ³H-2-deoxyglucose uptake activity and downstream glucose-dependent viability/proliferation. HEK293 transduces efficiently with lentivirus and supports stable rescue line generation.
