Removing IP6K1 in mouse brain increases sodium-potassium pumps, just as it does in the kidney and heart, indicating this gene may regulate these pumps in multiple organs through a shared mechanism.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
A systematic review would determine whether IP6K1 inhibition consistently upregulates NKA across all mammalian tissues and whether the magnitude of effect is comparable.
A systematic review and meta-analysis of all published studies measuring NKA expression in 10+ tissues (brain, kidney, heart, liver, muscle, etc.) following IP6K1 genetic deletion or pharmacological inhibition in mice and rats.
An RCT could determine whether systemic IP6K1 inhibition increases NKA in multiple tissues simultaneously in the same animals.
A double-blind, placebo-controlled trial in 40 mice, randomized to daily IP6K1 inhibitor (TNP, 10 mg/kg) or vehicle for 14 days, with NKA protein levels measured in brain, kidney, heart, liver, and skeletal muscle via immunoblotting in each animal.
A cohort study could determine whether IP6K1 expression levels inversely correlate with NKA levels across multiple tissues in the same individuals.
A prospective cohort of 60 mice, measuring IP6K1 mRNA and NKA protein levels in brain, kidney, heart, and liver from each animal, with multivariate correlation analysis across tissues.
A case-control study could determine whether IP6K1 knockout mice show NKA increases in all tissues tested, versus controls.
A case-control study comparing NKA levels in brain, kidney, heart, and liver tissue from 20 IP6K1 KO mice and 20 WT littermates, with standardized tissue processing and quantification.
A cross-sectional analysis could determine whether NKA levels are elevated in IP6K1 KO mice across multiple tissues at a single time point.
A cross-sectional analysis of NKA protein levels in brain, kidney, heart, and liver tissue from 15 IP6K1 KO and 15 WT mice, all measured simultaneously using identical protocols.
