Renal dopamine 2 receptor dysfunction is associated with oxidative stress and
high blood pressure (BP). We have reported that DJ-1, an oxidative stress
response protein, is positively regulated by dopamine 2 receptor in the kidney.
The transcription factor nuclear factor erythroid 2-related factor 2 (Nrf2)
regulates the expression of several antioxidant genes. We tested the hypothesis
that Nrf2 is involved in the renal DJ-1-mediated inhibition of reactive oxygen
species production. We have reported that silencing dopamine 2 receptor in mouse
renal proximal tubule cells decreases the expression of DJ-1. We now report that
silencing DJ-1 or dopamine 2 receptor in mouse proximal tubule cells and mouse
kidneys decreases Nrf2 expression and activity and increases reactive oxygen
species production; BP is also increased in mice in which renal DJ-1 or dopamine
2 receptor is silenced. DJ-1(-/-) mice have decreased renal Nrf2 expression and
activity and increased nitro-tyrosine levels and BP. Silencing Nrf2 in mouse
proximal tubule cells does not alter the expression of DJ-1 or dopamine 2
receptor, indicating that Nrf2 is downstream of dopamine 2 receptor and DJ-1. An
Nrf2 inducer, bardoxolone, normalizes the systolic BP and renal malondialdehyde
levels in DJ-1(-/-) mice without affecting them in their wild-type littermates.
Because Nrf2 ubiquitination is increased in DJ-1(-/-) mice, we conclude that the
protective effect of DJ-1 on renal oxidative stress is mediated, in part, by
preventing Nrf2 degradation. Moreover, renal dopamine 2 receptor and DJ-1 are
necessary for normal Nrf2 activity to keep a normal redox balance and BP.
