Alterations in transcription, RNA editing, translation, protein processing, and clearance are a consistent feature of Alzheimer's disease (AD) brain. To extend our initial study (Alzheimer Reports  3:161-167), RNA samples isolated from control and AD hippocampal cornu ammonis 1 (CA1) were analyzed for 12633 gene and expressed sequence tag (EST)… (More)
The cyclooxygenase (COX) superfamily of prostaglandin synthase genes encode a constitutively expressed COX-1, an inducible, highly regulated COX-2, and a COX-3 isoform whose RNA is derived through the retention of a highly structured, G + C-rich intron 1 of the COX-1 gene. As generators of oxygen radicals, lipid mediators, and the pharmacological targets of… (More)
To further understand the molecular mechanism of glucocorticoid action on gene expression, DNA-binding activities of the cis-acting transcription factors activator protein 1 (AP1), AP2, Egr1 (zif268), NF-kappaB, the signal transducers and activators of transcription proteins gamma interferon activation site (GAS), Sis-inducible element, and the TATA binding… (More)
1. Strong etiological association exists between dysfunctional metabolism of brain lipids, age-related changes in the cerebral vasculature and neurodegenerative features characteristic of Alzheimer's disease (AD) brain. 2. In this short review, recent experimental evidence for these associations is further discussed below.
Human epidermal keratinocytes (HEKs) in primary culture (P2-P4) were used to study glucocorticoid (GC)-mediated transcription of the genes encoding the constitutively expressed interleukin-1 type 1 receptor (IL-1R1) and the inducible interleukin-1 type 2 receptor (IL-1R2). Utilizing Northern dot blot analysis and a quantitative reverse… (More)
Interleukin-1beta (IL-1beta) and amyloid-beta peptide 42 (Abeta42) together induce a robust proinflammatory gene expression program in human neural cells in primary culture. One consistent genetic marker for this triggered inflammatory response is an increase in the expression of cycloooxygenase-2 (COX-2), a prostaglandin synthase also found to be… (More)
