Modulation of the sodium-chloride cotransporter by insulin in auditory cells: A potential link to diabetes-related hearing complications

These findings indicate that insulin promotes NCC phosphorylation, likely through the PI3K/PKB/WNK1 signaling pathway, with a possible contribution from cAMP/PKA signaling. This suggests that insulin-mediated NCC phosphorylation may influence inner ear sodium homeostasis. This mechanism could potentially contribute to the inner ear dysfunction observed in diabetes.
