Alzheimer's disease is a genetically complex disorder, for which new putative susceptibility genes are constantly proposed in the literature. We selected 16 candidate genes involved in biological pathways closely related to the pathology, and for which a genetic association with Alzheimer's disease was previously detected: ACE, BACE1, BDNF, ECE1, HSPG2,(More)
Recent epidemiological, biological and genetic data indicate a relationship between cholesterol and Alzheimer's disease (AD) including the association of polymorphisms of ABCA1 (a gene that is known to participate in cholesterol and phospholipid transport) with AD prevalence. Based on these data, we postulated that genetic variation in the related and(More)
Polymorphisms in the Nicastrin (NCSTN) gene have recently been associated with familial early-onset Alzheimer's disease (AD). The authors genotyped four NCTSN polymorphisms in a large cohort of 489 AD cases (including 158 sporadic early-onset AD cases and 95 familial early-onset AD cases) and 386 controls but failed to replicate the association between(More)
GPR88, coding for a G protein-coupled orphan receptor that is highly represented in the striatum, is a strong functional candidate gene for neuropsychiatric disorders and is located at 1p22-p21, a chromosomal region that we have previously linked to bipolar disorder (BD) in the Sardinian population. In order to ascertain the relevance of GPR88 as a risk(More)
Alzheimer's disease (AD) is a genetically complex neurodegenerative disorder and the leading cause of dementia of the elderly. Recently, Hu et al. suggested that a trinucleotide deletion in intron 13 of the APBB1 gene was a factor protecting against late-onset AD. We report here the results of a case/control study aimed at replicating this association. Our(More)
In tumours that harbour wild-type p53, p53 protein function is frequently disabled by the mouse double minute 2 protein (MDM2, or HDM2 in humans). Multiple HDM2 antagonists are currently in clinical development. Preclinical data indicate that TP53 mutations are a possible mechanism of acquired resistance to HDM2 inhibition; however, this resistance(More)
