The data from this study displays the complexity of the varicella-zoster virus (VZV) transcriptome architecture. VZV causes varicella and reactivates later in life to cause herpes zoster. The VZV genome is known to produce multitudes of overlapping transcripts and distinct open reading frames (ORFs) have been studied as well. However, the architecture of the VZV transcriptome remains unknown. This...

Previous study showed that exposure to arsenic, an environmental carcinogen, induces polyadenylation of canonical histone H3.1 mRNA. This study revealed that polyadenylation of H3.1 mRNA increases H3.1 protein, which results in displacement of histone variant H3.3 at active promoters, enhancers, and insulator regions. To investigate global changes in transcription induced by ectopic expression of polyadenylated...

The Allen Mouse Brain Atlas is a three-dimensional atlas of gene expression throughout the adult mouse brain. The atlas is separated into four key features:In Situ Hybridization (ISH) Data includes image data with cellular level resolution. To find gene expression data, search can be performed using Gene Search, Differential Search, Fine Structure Search, Bulk Search, and Human Differential Search.Reference...

Basal forebrain cholinergic neuron (BFCN) degeneration is an indicator of Down syndrome (DS) and Alzheimer’s disease (AD). The Ts65Dn (Ts) mouse model recapitulates both cognitive and morphological deficits of DS and AD, including BFCN degeneration. Therefore, this study used Ts mice to understand mechanisms underlying BFCN degeneration to identify novel targets for therapeutic intervention. They performed...

Neurological dysfunction associated with Down syndrome (DS) is the concomitant basal forebrain cholinergic neuron (BFCN) degeneration and onset of Alzheimer’s disease (AD) pathology. Previously, single population RNA sequencing analysis in the Ts65Dn (Ts) mouse model of DS revealed that the mitochondrial oxidative phosphorylation pathway was significantly impacted, where a large subset of genes within...

This study profiled neurotrophin and neurotrophin receptor gene expression within microdissected CA1 neurons along with regional hippocampal dissections from participants in the Rush Religious Orders Study (RROS). The RROS participants included older religious clergy who have agreed to medical and psychological evaluation each year and brain donation after death. This study began in 1993 and has enrolled...

This study investigated whether the Alzheimer’s disease (AD) pathological lesions diffuse plaques (DPs), neuritic plaques (NPs), and neurofibrillary tangles (NFTs). For this study, downregulation of brain-derived neurotrophic factor (BDNF) and its cognate neurotrophin receptor, TrkB, were observed during the progression of dementia. They performed negative binomial (NB) regressions using gene expression...

This study created an experimental model to assess the effects of early-life exposures to antibiotics on the intestinal microbiota and gene expression in the brain. For this study, C57BL/6 mice were breed for 5 days and the pregnant dams were randomized into 3 treatment groups. First group was treated with low-dose penicillin G in their drinking water starting during the last week of pregnancy and...

Choline is a vital nutrient that is used by the body to produce acetylcholine, which is an important neurotransmitter essential for brain and nervous system functions. Therefore, sufficient intake of dietary choline is important for proper brain function and neurodevelopment. It is especially critical for brain development during the perinatal period. This study investigated the impact of perinatal...

Patients with Alzheimer’s disease (AD) have altered intestinal microbiota. Studies have shown that reduced intestinal microbiota in AD animal models decreases amyloid-beta (Aβ) plaque deposition. This age-related changes in the microbiota contribute to immunologic and physiologic decline. Previous study indicated that calorie restriction (CR) reduced brain Aβ deposition in Tg2576 mouse model of AD....
