MetabolomicsWhole blood metabolomics of dementia patients reveal classes of disease-linked metabolites

Dementia is caused by factors that damage neurons. We quantified small molecular markers in whole blood of dementia patients, using non-targeted liquid chromatography-mass spectroscopy (LC-MS). Thirty-three metabolites, classified into 5 groups (A-E), differed significantly in dementia patients, ...

MetabolomicsMulti-omics reveals the protective mechanisms of Gastrodia elata ethyl acetate extract in vascular dementia

Objective: This study aimed to investigate the ameliorative effect of the ethyl acetate extract of Gastrodia elata (EEGE) on vascular dementia (VD) and its underlying mechanisms. 

Methods: A VD rat model was established using the two-vessel occlusion method, while an in vitro cerebral ...

MetabolomicsMetabolic phenotyping of urine from a dementia research cohort
To better understand the molecular mechanisms underpinning physiological variation in human populations, metabolic phenotyping approaches are increasingly being applied to studies involving hundreds and thousands of biofluid samples. Hyphenated ultra-performance liquid chromatography-mass spectromet...

TranscriptomicsGenome-wide DNA methylation analysis identifies epigenetic differences in Alzheimer’s disease and frontotemporal dementia in brain tissue and lymphoblastoid cell lines
We have performed methylation microarray analysis of two types of dementia, Alzheimer's disease (AD) and frontotemporal dementia (FTD), using two kind of samples, frozen brain tissue and lymphoblastoid cell lines.

TranscriptomicsInduced pluripotent stem cell models of progranulin-deficient frontotemporal dementia uncover specific reversible neuronal defects.
Multiple FTD patient-specific iPSC lines were generated for the first time, Human neurons of progranulin haploinsufficiency have been established. PGRN S116X neurons are more sensitive to kinase inhibitors-induced cell stress, which can be rescued by ectopic progranulin expression, revealing progran...

GenomicIndianapolis-Ibadan, Nigeria Comparative Epidemiological Study of Dementia

In 1991 collaboration between researchers at Indiana University School of Medicine and the University of Ibadan, Ibadan, Nigeria established the Indianapolis-Ibadan Dementia Project. It is a longitudinal, prospective population-based comparative epidemiological study of the prevalence and inciden...

ProteomicsIdentification of novel CSF biomarkers in GRN-associated frontotemporal dementia by proteomics
Frontotemporal dementia is the second most common form of presenile dementia and autosomal dominant inheritance is present in 20-30% of cases, with mutations in granulin (GRN) as a major cause. The exact pathophysiological mechanism by which GRN mutations lead to neurodegeneration is poorly understo...
