TAOK1 overexpression reduced kidney injury after ischemia-reperfusion in aged mice
In aged mice, the protein TAOK1 was lower in kidneys. Raising TAOK1 reduced kidney injury, inflammation and fibrosis after interrupted blood flow, alongside more mitophagy via the STK3/BNIP3 pathway. This is animal and cell research, not a human treatment. [1]

Aged mice, TAOK1 and kidney injury
Older people have more and more severe acute kidney injury, but the molecular reasons are poorly understood. This study asked whether the protein TAOK1 plays a role in age-related kidney injury, focusing on mitophagy — the cell's recycling of damaged mitochondria. The work used aged mice and cells from aged mice, not humans.

Interrupted blood flow plus TAOK1 in aged mice
Aged mice (23–24 months) underwent renal ischemia-reperfusion injury, meaning blood flow to the kidney was interrupted and then restored. TAOK1 was overexpressed in these mice. The researchers assessed kidney function, tissue changes, inflammation, neutrophil extracellular trap formation and fibrosis, and examined the STK3/BNIP3 pathway and mitophagy. In cells from aged mouse kidneys, TAOK1 was knocked down before low-oxygen and reoxygenation stress.

Less damage with more TAOK1 in aged mice
TAOK1 was significantly lower in kidneys of aged mice. Overexpressing TAOK1 lessened injury-induced kidney dysfunction, tubular damage, inflammation, neutrophil extracellular trap formation and fibrosis. It also activated the STK3/BNIP3 pathway and increased mitophagy markers. Knocking down TAOK1 in aged mouse kidney cells worsened cell injury and apoptosis and suppressed this pathway. The authors suggest the age-related decline in TAOK1 may contribute to greater susceptibility and call it a potential target — an association in animals, not proven cause or human benefit.
