Music elicits different gene expression responses in the buccal cavity of age-related cognitive disorders patients and healthy controls.

ABSTRACT: Recent evidence suggests that external stimuli can shape transcriptomes (sensogenomics). Specifically, the analysis of capillary blood samples has shown that musical stimuli can modulate gene expression patterns, in healthy individuals but also in those with age-related cognitive disorders (ACD), based on. Here, we present groundbreaking evidence indicating that brief exposure to music can also imACDt the salivary transcriptome in both healthy donors and ACD patients. Our findings reveal that music has a more pronounced effect on patients compared to CONTROLrols, inducing global gene expression changes towards upregulation in ACD patients but downregulation in CONTROLrols. The most significantly dysregulated genes in ACD patients include LGALS3 (downregulated) and CXCL8 (upregulated), whereas in CONTROLrols, THOP1 was the top significant gene (downregulated). These genes play important roles in normal brain functions and are also altered in neurodegenerative conditions. Weighted Gene Co-expression Network Analysis reveals relevant and significant modules, both positive and negative correlated with music, implicated in neurodegenerative (e.g. autophagy) and immunological processes (e.g. IL-1, MHC). This sheds light on the complex interplay between music and molecular responses in the human body. This study underscores the potential of musical stimuli to influence gene expression patterns outside of systemic circulation, paving the way for further exploration of music’s therapeutic effects.

Music compensates for altered gene expression in age-related cognitive disorders

Project description:Extensive literature has explored the beneficial effects of music in age-related cognitive disorders (ACD), but limited knowledge exists regarding its impact on gene expression. We analyzed transcriptomes of ACD patients and healthy controls, pre-post a music session (n=60), and main genes/pathways were compared to those dysregulated in mild cognitive impairment (MCI) and Alzheimer’s disease (AD) as revealed by a multi-cohort study (n=1269 MCI/AD and controls). Music was associated with 2.3 times more whole-genome gene expression, particularly on neurodegeneration-related genes, in ACD than controls. Co-expressed gene-modules and pathways analysis demonstrated that music impacted autophagy, vesicle and endosome organization, biological processes commonly dysregulated in MCI/AD. Notably, the data indicated a strong negative correlation between musically-modified genes/pathways in ACD and those dysregulated in MCI/AD. These findings highlight the compensatory effect of music on genes/biological processes affected in MCI/AD, providing insights into the molecular mechanisms underlying the benefits of music on these disorders.

Expression data from acd, p53 and double mutant mouse embryos

Project description:In mouse, the adrenocortical dysplasia (acd) phenotype shows limb and body axis anomalies, as a result of p53-dependent apoptosis, and perinatal lethality. The p53 deficiency partially rescues anomalies, but not perinatal lethality, implicating the involvement of p53-independent mechanisms in the acd phenotype. Differentially expressed genes in acd mutant and double mutant embryos were identified. p53-dependent and –independent pathways contributing to acd phenotype were characterized. We used microarrays to analyze gene expression profiles of acd and double mutant embryos and to identify p53 dependent and –independent mechanisms underlying acd phenotype.

Detection of non-coding deletion CNVs upstream to FOXF1 [Agilent-022084]

Project description:Genomic copy number analysis in patients with ACD/MPV. An unanticipated and tremendous amount of the non-coding sequences of the human genome are transcribed. Long non-coding RNAs (lncRNAs) are non-protein coding transcripts longer than 200 nucleotides and their functions remain enigmatic. We demonstrate that deletions of lncRNA genes cause a lethal lung developmental disorder, Alveolar Capillary Dysplasia with Misalignment of Pulmonary Veins (ACD/MPV), with parent of origin effects. We identify non-coding overlapping deletions 250 kb upstream to FOXF1 in nine patients with ACD/MPV that arose de novo specifically on the maternally inherited chromosome and delete a fetal lung-specific EST, part of an lncRNA. These deletions define distant cis-regulatory region that harbors a differentially methylated CpG island, binds GLI2 depending on the methylation status of this CpG island, and physically interacts with and up-regulates the FOXF1 promoter, consistent with the absence of the fetal lung-transcribed lncRNA perturbing FOXF1 regulation. LncRNA-mediated chromatin interactions may be responsible for position effect phenomenon and potentially cause many disorders of human development.potentially cause many disorders of human development. CNVs were identified by array CGH with custom-designed 16q24.1 region specific (1Mb flanking FOXF1) 44K oligonucleotide microarrays (Agilent technologies) in 3 patients with ACD. This Series contains data for only two patients custom targeted oligoarray, normal reference vs patient sample

Project description:miRNAs are kown to be deeply involved in the progression of chronic inflammatory diseases. We comprehensively analyzed miRNAs in human plasma from AD(atopic dermatitis) and ACD(allergic conjunctival disease) patients. We performed a comprehensive human plasma miRNA analysis and identified significantly up-regulated miRNAs in both AD (atopic dermatitis) and ACD (allergic conjunctival disease).

Comparative Transcriptomics of Choroid Plexus in Alzheimer's Disease, Huntington's Disease and Frontotemporal Dementia: Implications for CSF Homeostasis and Dynamics

Project description:Background: In aging and Alzheimer’s disease there are striking changes in CSF composition that may relate to altered choroid plexus function. Studying CP tissue gene expression at the BCSFB provides further insight into epithelial and stromal responses to aging and diseased states. Results: Highly significant differences in gene expression occurred in CP of advanced AD patients vs. normal controls. Immune-related pathways including acute phase response, cytokine/JAK/STAT signaling and cell adhesion were the most significantly enriched among the genes upregulated in AD patients, while methionine degradation, and protein translation genes were most notably downregulated. While the majority of gene expression changes in AD patients was also observed in FTD and HuD, there were significant differences among the disease groups. AD had the most unique expression findings, these genes being enriched in upregulated VEGF signaling and immune response proteins, e.g., interleukins. HuD/FTD patients uniquely displayed upregulated cadherin-mediated adhesion. Conclusions: This unique database of changes in CP tissue gene expression provides mechanistic insight into the effects of neurodegenerative diseases on CSF dynamics and hydrocephalus, particularly in regards to choroidal immune activation, metabolic homeostasis and resiliency of the CP.
