Key result
Elevated TRPM7 drives diabetic diastolic dysfunction via mitochondrial impairment, highlighting a novel target for HFpEF.
Observational analysis showed that TRPM7 is elevated in diabetic mice, indicating its role in heart dysfunction.
Hypomagnesemia (HypoMg) and subsequent oxidative stress cause diabetic cardiac diastolic dysfunction and heart failure with preserved ejection fraction. A Mg2+ transporter with channel and kinase function, transient receptor potential cation channel subfamily M 7 (TRPM7), is upregulated in HypoMg. Diabetes mellitus mice had HypoMg and elevated TRPM7 expression in the heart. TRPM7 kinase mediated mitochondrial dysfunction and cardiac diastolic dysfunction in HypoMg. TRPM7 kinase enhanced mitochondrial Fgr expression, with subsequent complex II dysfunction and mitochondrial reactive oxygen species overproduction. Inhibition of TRPM7 kinase represents a potential novel therapeutic strategy to treat diabetic heart failure with preserved ejection fraction.

Liu et al. (2025) studied Diabetic heart failure with preserved ejection fraction. TRPM7 kinase was evaluated on Mitochondrial dysfunction and cardiac diastolic dysfunction. Elevated TRPM7 expression in diabetes mellitus mice mediated mitochondrial and cardiac diastolic dysfunction, suggesting TRPM7 kinase inhibition as a potential therapeutic strategy for diabetic HFpEF.
