SLC8B1 Knockout HCT116 Cell Line

The choice depends on whether you are studying SLC8B1 (NCLX, mitochondrial Na+/Ca2+ exchanger)'s role in mitochondrial calcium efflux or its emerging functions in cancer metabolism and cell death regulation. The Knockout line is appropriate for asking whether NCLX is required for mitochondrial calcium extrusion — particularly relevant in colorectal cancer contexts where mitochondrial calcium dynamics affect bioenergetics and apoptosis sensitivity. Overexpression is useful for testing whether enhanced NCLX activity protects against calcium-induced mitochondrial dysfunction. For mitochondrial calcium research, the EDITGENE SLC8B1 Knockout in HCT 116 enables study of NCLX-MCU coupling — NCLX provides the dominant calcium efflux pathway counteracting MCU-mediated calcium uptake. Rescue with wild-type or transport-deficient NCLX enables mechanistic dissection of mitochondrial calcium homeostasis. NCLX inhibitors (CGP-37157) are research tools; the knockout serves as a genetic specificity control.

Primary applications: • Mitochondrial calcium efflux: mitochondrial calcium dynamics following IP3R-mediated calcium release using Rhod-2 AM or mitochondrial-targeted calcium sensors. • Mitochondrial bioenergetics: Seahorse OCR/ECAR analysis to assess NCLX's contribution to mitochondrial function in colorectal cancer cells. • Apoptosis sensitivity: assessment of mitochondrial calcium overload-induced apoptosis with and without NCLX activity. • NCLX inhibitor specificity: critical genetic control for testing CGP-37157 and other NCLX-targeting compounds. EDITGENE recommends this model for researchers investigating mitochondrial calcium homeostasis, cancer cell metabolism, and NCLX-targeted pharmacology.

Yes. NCLX rescue experiments require attention to mitochondrial inner membrane targeting: • Construct design: use a codon-modified SLC8B1 sequence with a small C-terminal tag (FLAG, HA). NCLX has 11 transmembrane domains and a mitochondrial targeting sequence — N-terminal modifications must not disrupt import. • Mitochondrial localization validation: confirm inner mitochondrial membrane localization by immunofluorescence co-staining with TOM20/inner membrane markers before functional assays. • Transport-deficient rescue: mutations in the calcium/sodium binding sites abolish exchange activity and serve as the standard specificity control. • Functional readout: rescue should restore mitochondrial calcium efflux measured by mitochondrial calcium imaging following IP3R-mediated cytosolic calcium elevation. HCT 116 transduces efficiently with lentivirus and supports stable mitochondrial rescue line generation.
