Genomewide effects of regular caffeine intake on hippocampal metabolism and learning-dependent transcription [RNA-Seq]

ABSTRACT: Caffeine is the most widely consumed psychoactive substance worldwide. Strikingly, molecular pathways engaged by its regular consumption remain unclear. We herein addressed the mechanisms associated with habitual (chronic) caffeine consumption in the mouse hippocampus using untargeted orthogonal-omics techniques. Our results revealed that caffeine exerts concerted pleiotropic effects in the hippocampus, at the epigenomic, proteomic and metabolomic levels, aimed at lowering metabolic-related processes while re-setting learning-associated transcriptome associated with neuronal activity. These processes involve BDNF, CREB and adenosine A2A receptors-related mechanisms. Altogether, these findings suggest that regular intake of caffeine improves the signal-to-noise ratio during information encoding in learning and bolsters the salience of information encoding in brain circuits.

Genomewide effects of regular caffeine intake on hippocampal metabolism and learning-dependent transcription [Cut & Tag]

Project description:Caffeine is the most widely consumed psychoactive substance worldwide. Strikingly, molecular pathways engaged by its regular consumption remain unclear. We herein addressed the mechanisms associated with habitual (chronic) caffeine consumption in the mouse hippocampus using untargeted orthogonal-omics techniques. Our results revealed that chronic caffeine exerts concerted pleiotropic effects in the hippocampus, at the epigenomic, proteomic and metabolomic levels, lowered metabolic-related processes in bulk tissue, while inducing neuronal-specific epigenetic changes at synaptic transmission/neuronal activity-related genes. Altogether, these findings suggest that regular intake of caffeine improves the signal-to-noise ratio during information encoding in learning in part through a re-setting of metabolic genes helping to bolster the salience of information processing in neuronal circuits.

Long-term caffeine treatment of Alzheimer mouse models ameliorates behavioural deficits and neuron loss and promotes cellular and molecular markers of neurogenesis

Project description:Epidemiological studies suggest that consumption of caffeine, the most commonly consumed psychoactive substances found in coffee, tea or soft drinks reduces the risk of developing Alzheimer’s disease (AD). While previous studies employing transgenic AD mouse models reported on reduced amyloid plaque load or an amelioration of behavioral deficits, there is only limited information on its potential effects on neurodegeneration. In the current study, we assessed whether long-term caffeine consumption affects hippocampal neuron loss and associated behavioral deficits in the Tg4-42 mouse model of AD. Treatment over a 4 months period reduced hippocampal neuron loss, rescued learning and memory deficits and ameliorates impaired neurogenesis. Neuron-specific hippocampal transcriptome analysis revealed an altered expression profile with an up-regulation of genes linked to synaptic function and processes, as well as neural progenitor proliferation. Treatment of 5xFAD mice with the same paradigm also rescued behavioral deficits, however, without affecting extracellular amyloid-beta (Abeta) levels or altered APP processing.

Comparative Effects of Arecoline, Caffeine, and Nicotine on Transcription Level in the NAc of Mice

Project description:Though widely consumed, current research on the neural mechanisms of arecoline, caffeine, and nicotine remains limited, and the similarities and differences of these three substances on the nervous system are still not clear. This study used RNA-seq to analyze the gene expression in the nucleus accumbens (NAc) of mice, and further compared the behavioral changes through open field and conditioned place preference (CPP), exploring the effects of different psychoactive substances at the transcriptional and behavioral levels. Gene Ontology enrichment analysis revealed that nicotine and caffeine significantly alter biological processes related to synaptic function, and KEGG pathway analysis showed that the differentially expressed genes in the nicotine-treated group were significantly more enriched in pathways related to substance dependence compared to the other two treatment groups, with arecoline showing the least enrichment. Furthermore, only acute caffeine treatment significantly increased mouse activity, and only nicotine induced CPP. These results provided a scientific basis for evaluating the effects of arecoline, caffeine, and nicotine on the nervous system.

Characterization of caffeine response regulatory variants in vascular endothelial cells

Project description:Genetic variants in gene regulatory sequences can modify gene expression and mediate the molecular response to environmental stimuli. In addition, genotype–environment interactions (GxE) contribute to complex traits such as cardiovascular disease. Caffeine is the most widely consumed stimulant and is known to produce a vascular response. To investigate GxE for caffeine, we treated vascular endothelial cells with caffeine and used a massively parallel reporter assay to measure allelic effects on gene regulation for over 43,000 genetic variants. We identified 665 variants with allelic effects on gene regulation and 6 variants that regulate the gene expression response to caffeine (GxE, false discovery rate [FDR] < 5%). When overlapping our GxE results with expression quantitative trait loci colocalized with coronary artery disease and hypertension, we dissected their regulatory mechanisms and showed a modulatory role for caffeine. Our results demonstrate that massively parallel reporter assay is a powerful approach to identify and molecularly characterize GxE in the specific context of caffeine consumption.

Does Caffeine Reduce Postoperative Bowel Paralysis After Elective Colectomy?

Project description:Postoperative bowel paralysis is common after abdominal operations, including colectomy. As a result, hospitalization may be prolonged leading to increased cost. A recent randomized controlled trial from the University of Heidelberg showed that consumption of regular black coffee after colectomy is safe and associated with a significantly faster resumption of intestinal motility (Müller 2012). The mechanism how coffee stimulates intestinal motility is unknown but caffeine seems to be the most likely stimulating agent. Thus, this trial addresses the question: Does caffeine reduce postoperative bowel paralysis after elective laparoscopic colectomy? Patients after laparoscopic colectomy will receive either 100 mg caffeine, 200 mg caffeine, or 250mg corn starch (placebo) 3 times daily in identically looking gelatin capsules. The study is a randomized, controlled trial, with blinding of physicians, patients and nursing stuff (evaluating the endpoints). Primary endpoint will be the time to first bowel movement.
