Nuclear import and export signals control the subcellular localization of Nurr1 protein in response to oxidative stress.
García-Yagüe ÁJ, Rada P, Rojo AI, Lastres-Becker I, Cuadrado A
Nurr1, a protein critical for dopamine neuron health, moves between the nucleus and cytoplasm using specific signals. Oxidative stress pushes Nurr1 out of the nucleus, reducing its ability to protect neurons and control key genes. Antioxidants can reverse this shift, suggesting a potential way to support Nurr1 function in NR4A2-related conditions.
- Nurr1 shuttles between nucleus and cytoplasm via specific import and export signals
- Oxidative stress causes Nurr1 to leave the nucleus, impairing its protective role
- Antioxidants like N-acetylcysteine can restore nuclear Nurr1 levels
- This movement affects expression of genes vital for dopamine neuron function
- Targeting Nurr1 localization may offer a treatment strategy for NR4A2-related disorders

Restriction of neural precursor ability to respond to Nurr1 by early regional specification.
Soldati C, Cacci E, Biagioni S, Carucci N, Lupo G, Perrone-Capano C, Saggio I, Augusti-Tocco G
Nurr1 can only turn neural precursor cells into dopamine-producing neurons if they come from specific brain regions during early development, not from others or from adult brain tissue. This shows that the ability to become dopamine neurons is lost as brain regions become specialized.
- Nurr1 only works in early brain precursors from midbrain and ganglionic eminence
- Cortex and spinal cord cells cannot become dopamine neurons with Nurr1
- Adult brain precursors also fail to respond to Nurr1
- Brain region identity limits Nurr1's ability to drive dopamine development
- Early brain development locks in cell fate potential

Cocaine disrupts the development of dopamine-producing neurons in zebrafish by altering the expression of key genes involved in their formation and function, including Nurr1 and Lmx1b, which are also critical in human NR4A2-related disorders. These changes affect dopamine system development at multiple stages, suggesting that early exposure to cocaine may interfere with the same pathways affected in NR4A2 syndrome.
- Cocaine alters genes critical for dopamine neuron development
- Nurr1 and Lmx1b expression are disrupted by cocaine
- Gene changes affect dopamine system timing and location
