SLC60A2 Knockout HCT 116 Cell Line

The choice depends on whether you are studying SLC60A2 (MFSD4B)'s role as a sodium-dependent hexose transporter or its emerging functions in urea transport in the renal inner medulla. Note that SLC60A2 is the current HGNC-approved symbol; this gene is also widely referred to as MFSD4B in published literature and has been characterized as a sodium-dependent glucose and fructose transporter (Horiba et al., 2003), with more recent evidence suggesting a potential role as a urea channel. The Knockout line is appropriate for asking whether SLC60A2 is required for these transport activities, with the caveat that its principal physiological site is the renal inner medulla rather than colorectal tissue. Overexpression is useful for transport activity characterization in heterologous systems — HCT 116 background, while a colorectal cancer line, can serve as a tractable expression context. For SLC60A2 research, the EDITGENE Knockout in HCT 116 is most informative for biochemical and inhibitor specificity studies; physiologically relevant function research (renal fructose/urea handling, kidney medulla biology) requires kidney-derived models. Rescue with wild-type or transport-deficient SLC60A2 enables structure-function studies and substrate specificity characterization.

Primary applications: • Hexose transport assays: cellular uptake of ³H-glucose, ³H-fructose, or LC-MS-based monosaccharide uptake measurements under sodium-replete versus sodium-free conditions to characterize SLC60A2-mediated transport. • Urea transport studies: assessment of urea flux through SLC60A2 — relevant to its proposed role as a urea channel in renal inner medulla physiology. • Paralog studies: SLC60A1 (MFSD4A) expression analysis to interpret SLC60A2-specific functions given the close relationship between these paralogs. • Heterologous transport characterization: rescue with wild-type SLC60A2 enables systematic substrate scope testing in a defined cellular background. EDITGENE recommends this model for researchers investigating MFSD4 family transporter biology and sodium-dependent hexose transport mechanisms. Physiological renal medulla studies require kidney-derived cell systems.

Yes. SLC60A2 rescue experiments require attention to membrane topology and sodium-coupled transport mechanism: • Construct design: use a codon-modified SLC60A2 sequence with a small C-terminal tag (FLAG, HA). SLC60A2/MFSD4B is a Major Facilitator Superfamily transporter with 12 predicted transmembrane domains — N-terminal tags must not disrupt membrane topology. • Transport-deficient rescue: sodium-binding or substrate-binding pocket mutations enable distinguishing transport activity from non-transport functions; comparison with the SLC60A1 paralog can inform residue selection. • Surface localization validation: confirm plasma membrane localization of exogenous SLC60A2 by cell surface biotinylation or imaging before transport assays — apical targeting in epithelial contexts may require specific sorting signals. • Functional readout: rescue should restore sodium-dependent glucose and fructose uptake measured by radiolabel or LC-MS detection. HCT 116 transduces efficiently with lentivirus and supports stable rescue line generation; the colorectal cancer background is appropriate for biochemical mechanism studies but does not fully recapitulate the renal medulla physiological context.
