Project description:Cancer-related fatigue is one of the most frequent complaints among breast cancer survivors, with a major negative impact on general life. However, the etiology behind this syndrome is still unraveled. Gene expression analysis was performed on whole blood samples from breast cancer survivors classified as either fatigued or non-fatigued at two consecutive time points. The analysis identified several gene sets concerning plasma and B cell pathways as different between the fatigue and non-fatigue groups, suggesting that a deregulation in these pathways might underlie the fatigue syndrome. The fatigue group also showed a higher mean level of leucocytes, lymphocytes and neutrophiles compared with the non-fatigue group, thus further implicating the immune system in the biology behind the fatigue syndrome. Keywords: Blood RNA and late side effects

Keywords: Blood RNA and late side effects Breast cancer survivors treated with adjuvant radiotherapy at The Norwegian Radium Hospital between 1998 and 2002 were invited to participate in a study assessing late treatment effects in breast cancer survivors. In the present study, gene expression analysis was performed on whole blood samples from breast cancer survivors with and without persistent fatigue, to look for different expression patterns that might shed light on the biology behind cancer-related fatigue.

Project description:HIV-related fatigue is multi-causal in origin and potentially related to mitochondrial dysfunction caused by toxicity from nucleoside reverse transcriptase inhibitor (NRTI) antiretroviral therapy. CD14+ cells are undifferentiated macrophages, vulnerable to HIV infection, and easily accessible for gene expression experiments in a purified cell population. We utilized a novel mitochondrially-specific gene expression microarray to assess mitochondrial and nuclear genes in CD14+ cells of low- and high-fatigued, NRTI-treated HIV/AIDS patients (n=5 each). Novel Bayesian and liquid association network methods identified 33 genes predictive of low versus high fatigue and 32 genes predictive of healthy versus HIV infection. Sulfotransferase 2B1 (SULT2B1) is relevant to both the cholesterol and testosterone pathway, and like several inner mitochondrial membrane genes also identified, predictive of fatigue status, while outer mitochondrial membrane genes were predictive of HIV status. A surprising finding was that adenylate cyclase 2 (ADCY2) was a predictor of both HIV and fatigue; it had the highest Kendallâs Tau association value in the HIV group, but in reverse, the lowest Tau value in the fatigue group. Assaying CD14+ cells may provide an alternative to muscle biopsy and a minimally invasive procedure to evaluate patient mitochondrial function, and Bayesian and network tools are useful to identify the link between subjective symptom perceptions and underlying biologically pathways. Fatigue status in HIV patients treated with NRTIs was found to be linked to RNA expression differences related to mitochondrial function. Additional studies are needed to confirm the relevance of our findings in CD14+ cells in other tissues (e. g. skeletal muscle) and to understand the significance of key genes such as SULT2B and ADCY2 in fatigue and HIV disease. The design was a comparison of HIV high fatigue to HIV low fatigue. Low fatigue was determined as 3-7 on the Revised Piper Fatigue Score and High fatigue was a score of 7 or greater. Five HIV negative control samples were used to compare normal fatigue and non-disease status.

Project description:Genome-wide analysis of DNA methylation profiles from patients with Sjögren's syndrome with high versus low fatigue levels using the Illumina Infinium HumanMethylation450 Beadchip array. Background Chronic fatigue is a common, disabling, and poorly understood phenomenon. Recent studies indicate that epigenetic mechanisms may be involved in the expression of fatigue, a prominent feature of primary Sjögrenâs syndrome (pSS). The aim of this study was to investigate whether DNA methylation profiles of whole blood are associated with fatigue in patients with pSS. Methods 48 pSS patients with high (n=24) or low (n=24) fatigue as measured by a visual analogue scale were included. Genome-wide DNA methylation was investigated using the Illumina HumanMethylation450 BeadChip array. Case-case study including Sjögren's patients with high fatigue (n=24) and patients with low fatigue levels (n=24)

Project description:Fatigue is a debilitating condition with a significant impact on patients’ quality of life. Fatigue is frequently reported by patients suffering from primary Sjo ̈gren’s Syndrome (pSS), a chronic autoimmune condition characterised by dryness of the eyes and the mouth. However, although fatigue is common in pSS, it does not manifest in all sufferers, providing an excellent model with which to explore the potential underpinning biological mechanisms.

Project description:Objective: To evaluate gene expression profiles in multiple sclerosis (MS) patients who improved their fatigue status after a program of physical exercise and to compare them with healthy controls (HC). Methods: A prospective longitudinal study was conducted. Gene expression in whole blood was profiled at baseline in 7 healthy controls and also in 7 fatigued-MS patients. Patients underwent a physical exercise program for 6 months, and their fatigue status and gene expression profiles were again analyzed at the end of this program. Results: MS patients showed a significant activation of genes participating in the systemic interferon response in comparison with healthy controls. Fatigue improved at the end of the physical activity program, and, in parallel, systemic activation of interferon related genes disappeared. Conclusions: Fatigue improvement following an exercise program is associated to down modulation of interferon activity at the systemic level in MS patients. Our results provide a biological basis for the observed benefit of physical exercise in MS.

Project description:Background. Chronic fatiguing illness remains a poorly understood syndrome of unknown pathogenesis. We attempted to identify biomarkers for chronic fatiguing illness using microarrays to query the transcriptome in peripheral blood leukocytes. Methods. Cases were 44 individuals who were clinically evaluated and found to meet standard international criteria for chronic fatigue syndrome or idiopathic chronic fatigue, and controls were their monozygotic co-twins who were clinically evaluated and never had even one month of impairing fatigue. Biological sampling conditions were standardized and RNA stabilizing media were used. These methodological features provide rigorous control for bias resulting from case-control mismatched ancestry and experimental error. Individual gene expression profiles were assessed using Affymetrix Human Genome U133 Plus 2.0 arrays. Findings. There were no significant differences in gene expression for any transcript. Conclusions. Contrary to our expectations, we were unable to identify a biomarker for chronic fatiguing illness in the transcriptome of peripheral blood leukocytes suggesting that positive findings in prior studies may have resulted from experimental bias. Cases were 44 individuals who were clinically evaluated and found to meet standard international criteria for chronic fatigue syndrome or idiopathic chronic fatigue, and controls were their monozygotic co-twins who were clinically evaluated and never had even one month of impairing fatigue.
