Prenatal exposure to nicotine impairs performance of the 5-choice serial reaction time task in adult rats.
Schneider T, Ilott N, Brolese G, Bizarro L, Asherson PJ, Stolerman IP
Prenatal nicotine exposure in rats leads to lasting attention and impulse control problems in adulthood, including difficulty focusing, increased errors, and slower learning, even though other behaviors like movement and decision-making were unaffected. The changes were linked to increased dopamine receptor levels in the brain's reward center.
- Nicotine exposure before birth harms attention and learning in adult rats
- Rats showed more errors, slower responses, and poor task learning
- Brain changes included higher D5 dopamine receptor levels
- No effect on general movement or reward preference

Boon WC, Petkovic-Duran K, White K, Tucker E, Albiston A, Manasseh R, Horne MK, Aumann TD
Acoustic micromixing dramatically improves the efficiency of reverse transcription from tiny amounts of RNA, making it possible to detect low-abundance genes like NR4A2 (Nurr1) that are usually missed in single-cell studies. This technique boosts cDNA yields so much that it’s equivalent to using 10 to 100 times more RNA, which is critical for studying genes with very low expression.
- Micromixing boosts cDNA detection from single-cell RNA
- Enables detection of previously undetectable low-abundance genes like NR4A2
- Most effective at single-cell RNA levels (0.1–1 pg/µL)
- Improves mixing efficiency for low-concentration RNA
- Could improve accuracy in single-cell gene expression studies

- BHD boosted dopamine-producing cells in the substantia nigra
- Treatment helped repair damaged brain neurons
- Findings suggest BHD may support brain function in Parkinson’s
Chronic methamphetamine exposure suppresses the striatal expression of members of multiple families of immediate early genes (IEGs) in the rat: normalization by an acute methamphetamine injection.
McCoy MT, Jayanthi S, Wulu JA, Beauvais G, Ladenheim B, Martin TA, Krasnova IN, Hodges AB, Cadet JL
Chronic methamphetamine use in rats reduces the brain's ability to activate key genes involved in neural responses, including NR4A2 (Nurr1), which is linked to movement and reward. While most gene responses are restored by a single methamphetamine dose, NR4A2 levels drop further, suggesting a unique vulnerability in this gene. This may help explain why people with addiction keep using the drug despite negative effects.
- Chronic methamphetamine blunts brain gene responses
- NR4A2 (Nurr1) levels drop further after meth exposure
- Some genes return to normal after a single dose
- NR4A2 is uniquely sensitive to meth-induced suppression
- This may explain repeated drug use in addiction

This model helps reveal how these genes protect blood stem cells and may guide future treatments.
- NR4A1 and NR4A3 loss causes MDS/MPN-like disease in mice
- Blood stem cells show too much death and too much growth
- DNA damage and faulty repair drive the disease
- Egr1, JunB, and Plk2 are disrupted genes involved

Retinoid X receptor α acts as a negative regulator in Nurr1-induced dopaminergic differentiation in rat neural precursor cells.
Retinoid X receptor alpha (RXRα) blocks the ability of Nurr1 to turn neural precursor cells into dopamine-producing neurons in rats. This suggests RXRα may interfere with brain development pathways relevant to NR4A2-related disorders.
- RXRα stops Nurr1 from making dopamine neurons
- Nurr1 is the human gene NR4A2
- Findings are in rat brain cells, not humans
- May explain why some NR4A2 mutations cause problems
- Suggests RXRα could be a treatment target
Retinoid X receptor α acts as a negative regulator in Nurr1-induced dopaminergic differentiation in rat neural precursor cells.
Yoon EH, Lee KJ, Kim YS, Chang MS, Lee SH, Park CH
RXRα suppresses Nurr1's ability to activate the gene for tyrosine hydroxylase, a key enzyme in dopamine production, in rat neural precursor cells. This suggests RXRα may act as a brake on dopamine neuron development, which could be relevant for understanding or treating NR4A2-related disorders.
- RXRα reduces Nurr1's activity in making dopamine neurons
- RXRα suppresses the TH gene promoter
- The Nurr1-RXRα pair acts as a repressor, not an activator

Moroni RF, Cipelletti B, Inverardi F, Regondi MC, Spreafico R, Frassoni C
This study used a rat model exposed to BCNU to mimic cortical dysplasia, showing that a single early brain injury disrupts brain development by damaging the structure that guides neuron movement, leading to abnormal neuron clusters and disrupted brain layering. These findings help explain how brain malformations form after early developmental insults.
- BCNU exposure disrupts brain structure guiding neuron movement
- Neurons end up in wrong places, forming abnormal clusters
- Disrupted brain layering appears early and persists

Decreased level of Nurr1 in heterozygous young adult mice leads to exacerbated acute and long-term toxicity after repeated methamphetamine exposure.
Luo Y, Wang Y, Kuang SY, Chiang YH, Hoffer B
Reduced Nurr1 levels in young adult mice make their dopamine system more vulnerable to damage from repeated methamphetamine use, especially if they were exposed to methamphetamine as adolescents. This suggests that people with NR4A2 gene variants may be at higher risk for long-term brain damage from stimulant use.
- NR4A2/Nurr1 deficiency increases brain damage from methamphetamine
- Adolescent meth use worsens long-term dopamine system harm
- Nurr1 levels may predict vulnerability to stimulant toxicity

Bousquet M, Gue K, Emond V, Julien P, Kang JX, Cicchetti F, Calon F
Increasing omega-3 fatty acids in the brain through genetic modification did not protect mouse brain cells from Parkinson’s-like damage, but higher levels of DHA in the brain were linked to better survival of dopamine-producing neurons. This suggests that directly supplementing DHA in the diet may be more effective than relying on the body to make it from other fats.
- Genetically boosting omega-3s in mice did not prevent brain damage in a Parkinson’s model
- Higher brain DHA levels were linked to healthier dopamine neurons
- Dietary DHA supplements may be more effective than internal conversion
- DHA may support the function of Nurr1, a key protein in Parkinson’s
- The brain needs sufficient DHA levels to support neuron protection
The orphan nuclear receptor Nurr1 restricts the proliferation of haematopoietic stem cells.
Sirin O, Lukov GL, Mao R, Conneely OM, Goodell MA
Nurr1 is a key regulator that keeps blood stem cells dormant and prevents them from dividing. When Nurr1 levels are too high, stem cells stop dividing and cannot regenerate blood; when Nurr1 levels are too low, stem cells start dividing uncontrollably. This suggests Nurr1 helps maintain the balance between stem cell rest and activity.
- Nurr1 keeps blood stem cells in a resting state
- Too little Nurr1 causes stem cells to over-proliferate
- Too much Nurr1 blocks stem cell function
- Nurr1 works by increasing p18, a cell cycle brake
- This balance is critical for healthy blood production

- They mark early motor cortex development at 8–12 weeks
- These genes help form corticospinal neurons for movement control

- Nurr1 guides nerve cell maturation and movement in developing rat brains
- Nurr1 is not present in dividing cells, only in maturing ones
- Nurr1 levels peak in early postnatal brain development and fade with maturity

Selective regulation of nuclear orphan receptors 4A by adenosine receptor subtypes in human mast cells.
Zhang L, Paine C, Dip R
Adenosine signaling in human mast cells regulates NR4A2 and NR4A3 through a pathway involving PKC and ERK, with the A(2A) adenosine receptor acting as a brake on this response. This suggests that drugs targeting A(2A) receptors might influence inflammation and cell regulation in conditions involving NR4A2 dysfunction.
- NR4A2 and NR4A3 are boosted by adenosine in human mast cells
- A(2A) receptor activation reduces NR4A2/3 induction
- PKC and ERK pathways link adenosine to NR4A2/3 regulation
- Blocking A(2A) receptor increases NR4A2/3 levels
- This pathway may respond to other mast cell triggers too
