Experimental evidence supports a protective role of estrogen in the brain. According to the fact that Alzheimer's disease (AD) is more common in postmenopausal women, estrogen treatment has been proposed. However, there is no general consensus on the beneficial effect of estrogen or selective estrogen receptor modulators in preventing or treating AD. It has to be said that several factors may m...

background: the seladin-1 (selective alzheimer disease indicator-1), also known as dhcr24, is a gene found to be down-regulated in brain region affected by alzheimer disease (ad). whereas, hair follicle stem cells (hfsc), which are affected in with neurogenic potential, it might to hypothesize that this multipotent cell compartment is the predominant source of seladin-1. our aim was to evaluate...

Oxidative stress plays a major role in the pathogenesis of Alzheimer's disease (AD) of sporadic origin. The expression of DHCR24 (Seladin-1), marker for neuronal oxidative stress and degeneration, has been reported to be altered in the brains of AD patients. In the present study, we investigated the effect of trimetazidine (TMZ) on the hippocampal oxidative parameters and the expression of DHCR...

The endocrine and the nervous system are closely correlated throughout life, starting from the embryo and until the late stages of life. Alzheimer's disease (AD) is the most common neurodegenerative disease associated with ageing. Unfortunately, an effective way to prevent or to cure this disease does not exist, so far. There is evidence that estrogens exert neuroprotective properties, although...

BACKGROUND AND PURPOSE 3β-Hydroxysteroid-Δ24 reductase (DHCR24) or selective alzheimer disease indicator 1 (seladin-1), an enzyme of cholesterol biosynthetic pathway, has been implicated in neuroprotection, oxidative stress, and inflammation. However, its role in ischemic stroke remains unexplored. The aim of this study was to characterize the effect of seladin-1/DHCR24 using an experimental st...

The objective is to evaluate the effect of heme oxygenase-1 (HO-1) enzyme inducer and inhibitor on Mesenchymal Stem Cells (MSCs) in Alzheimer disease. 70 female albino rats were divided equally into 7 groups as follows: group 1: healthy control; group 2: Aluminium chloride induced Alzheimer disease; group 3: induced Alzheimer rats that received intravenous injection of MSCs; group 4: induced Al...

Selective Alzheimer's Disease Indicator-1 (Seladin-1) was originally identified by its down-regulation in the brains of Alzheimer's disease (AD) patients. Here, we re-examine existing data and present new gene expression data that refutes its role as a selective AD indicator. Furthermore, we caution against the use of the name "Seladin-1" and instead recommend adoption of the approved nomenclat...
