(Submitter supplied) Numerous neurological disorders, including Alzheimer's disease, display a sex-biased prevalence. To identify molecular correlates of this sex bias, we investigated sex-differences in molecular pathology in the hippocampus using the 5XFAD mouse model of Alzheimer's disease during early stages of disease progression (1, 2, and 4 months of age).

(Submitter supplied) Identifying sex differences in gene expression within the brain is critical for determining why multiple neurological and behavioral disorders differentially affect males and females. Several are more common or severe in males (e.g., autism and schizophrenia) or females (e.g., Alzheimer’s disease and depression). We analyzed transcriptomic data from the mouse hippocampus of six inbred strains (129S1/SvImJ, A/J, C57BL/6J, DBA/1J, DBA/2J and PWD/Ph), to provide a perspective on differences between male and female gene expression. more...

(Submitter supplied) We analyzed the transcriptome of the C57BL/6J mouse hypothalamus, hippocampus, neocortex, and cerebellum to determine estrous cycle-specific changes in these four brain regions. We found almost 16,000 genes are present in one or more of the brain areas but only 210 genes, ~1.3%, are significantly changed as a result of the estrous cycle. The hippocampus has the largest number of differentially expressed genes (DEGs) (82), followed by the neocortex (76), hypothalamus (63), and cerebellum (26). more...

(Submitter supplied) A variety of neurological disorders, including Alzheimer’s disease, Parkinson’s disease, major depressive disorder, dyslexia and autism, are differentially prevalent between females and males. To better understand the possible molecular basis for the sex-biased nature of neurological disorders, we measured both mRNA and protein in the hippocampus of female and male mice at 1, 2, and 4 months of age with RNA-sequencing and mass-spectrometry respectively. more...

(Submitter supplied) Transcriptome analysis of hippocampal RNA samples from wild-type, 5xFAD, 5xFAD;eIF2α+/S51A and eIF2α+/S51A mice Our transcriptome analyses showed clear transcriptional alterations in hippocampi of 5xFAD compared to wild type mice that were not corrected by the eIF2αS51A allele.

(Submitter supplied) we conducted a detailed phenotypic characterization of the 5xFAD model on a congenic C57BL/6J strain background, across its lifespan – including a seldomly analyzed 18-month old time point to provide temporally correlated phenotyping of this model and a template for characterization of new models of LOAD as they are generated. This comprehensive analysis included quantification of plaque burden, Aβ biochemical levels, and neuropathology, neurophysiological measurements and behavioral and cognitive assessments, and evaluation of microglia, astrocytes, and neurons. more...

(Submitter supplied) Physical activity is considered a promising preventive intervention to reduce the risk of developing Alzheimer’s disease (AD). However, the positive effect of exercise therapy has not been proven conclusively yet, likely due to confounding factors such as varying activity regimens and life or disease stages. To examine the impact of different exercise regimens in the early disease stages, we subjected young 5xFAD and wild-type mice to 1-day (acute, 3-month-old) and 30-day (chronic, 2-month-old) voluntary wheel running and compared them with age-matched sedentary controls. more...

(Submitter supplied) Sex differences in the brain as they relate to health and disease are often overlooked in experimental models. Many neurological disorders, like Alzheimer’s disease (AD), multiple sclerosis (MS), and autism, differ in prevalence between males and females. Sex differences originate either from differential gene expression on sex chromosomes or from hormonal differences, either directly or indirectly. more...

(Submitter supplied) The systemic delivery of tamoxifen (Tam) to activate inducible CreERT2-loxP transgenic mouse systems is now widely used in neuroscience studies. This critical technological advancement allows temporal control of DNA-cre recombination, avoidance of embryonically lethal phenotypes, and minimization of residual cell labeling encountered in constitutively active drivers. Despite its advantages, the use of Tam has the potential to cause long-lasting, uncharacterized side effects on the transcriptome and epigenome in the CNS, given its mixed estrogen receptor (ER) agonist/antagonist actions. more...

(Submitter supplied) Long-term memory formation is dependent on gene expression changes in the hippocampal region of the brain. Aging-related memory impairments and incidence of pathological memory disorders such as Alzheimer’s disease differ between males and females, and yet little is known about how aging-related changes to the transcriptome and chromatin environment differs between sexes in the hippocampus. To investigate this question, we compared the chromatin accessibility landscape and gene expression/alternative splicing pattern of young adult and aged mouse hippocampus of both males and females using ATAC-seq and RNA-seq. more...

(Submitter supplied) Alzheimer’s disease (AD), the most common age-related neurodegenerative disease, is closely associated with and manifested by neuroinflammation, yet the alteration of immune landscape in AD is largely unknown, preventing a deeper mechanistic understanding of neuroinflammation in AD. Two thirds of AD patients are females, and women have a higher risk of developing AD. Women with AD have more extensive brain histological changes than men with AD, more severe cognitive symptoms, and more severe neurodegeneration, suggesting that the disease affects female and male brains differentially. more...
