Substantia nigra and blood gene signatures and biomarkers for Parkinson’s disease from integrated multicenter microarray-based transcriptomic analyses [PDF]
Frontiers in Aging NeuroscienceBackgroundParkinson’s disease (PD) is a complex, common neurodegenerative disorder with unclear etiology. The pathogenic hallmark is the death of dopaminergic neurons in the substantia nigra. PD diagnosis depends on clinical manifestation of symptoms but

Stable Dopamine-Signaling mRNA Co-Expression in the Substantia Nigra Is Deregulated in Pathological Conditions, but Not in Dopamine Transporter Knockout Rats [PDF]
BiomoleculesDopamine transporter (DAT) mutations are associated with neurological and psychiatric diseases, and DAT gene knockout in rats (DAT-KO) provides an opportunity to evaluate the DAT role in pathological conditions.

Illicit stimulant use is associated with abnormal substantia nigra morphology in humans. [PDF]
PLoS ONE, 2013 Use of illicit stimulants such as methamphetamine, cocaine, and ecstasy is an increasing health problem. Chronic use can cause neurotoxicity in animals and humans but the long-term consequences are not well understood. The aim of the current study was to

Crystals in the Substantia Nigra [PDF]
ACS Chemical Neuroscience, 2019 Crystals of TiO2 and CaO were detected in electron-beam exposed extracts of four substantia nigra specimens of Parkinson's disease donors. A likely precursor of the CaO crystals is inflammatory calcium oxalate dihydrate, decomposing according to CaC2O4·2H2O → CaO + CO↑ + CO2↑ + 2H2O↑.

Measurement of the adult human midbrain with transcranial ultrasound.
PLoS ONE, 2021 BackgroundTranscranial sonography is increasingly used to aid clinical diagnoses of movement disorders, for example, to identify an enlarged area of substantia nigra echogenicity in patients with Parkinson's disease.ObjectiveThe current study ...

MRI T2 and T2* relaxometry to visualize neuromelanin in the dorsal substantia nigra pars compacta
NeuroImage, 2020 Visualizing gradual changes in neuromelanin distribution within the substantia nigra is an important metric used to monitor the progression of Parkinsonism.
