Project description:Intermittent fasting (IF) reduces the inflammatory symptoms of Rheumatoid Arthritis (RA); however, its anti-inflammatory underlying molecular mechanisms are unknown. Aim: To investigate the effect of IF on joint inflammatory molecular mechanisms in collagen-induced arthritis (CIA) through DNA microarray and clinical and histopathological evaluations. Methods: CIA was induced in sixteen male DBA/1 mice divided into two groups, one received every other day IF for four weeks. The clinical, histological, and transcriptomic analyses, through DNA microarray, were done to evaluate the effect of IF on joint inflammation and remodeling. Results: CIA mice with IF show lower arthritis incidence and severity. IF also decreased the histological inflammation and joint damage. DNA microarrays dataset revealed 364 overexpressed and 543 subexpressed genes. The highest over- and subexpressed genes were the Ereg and MUPs, respectively. Retinol biosynthesis and the macrophage alternative activation pathways were associated with a positive z-score. Pathways with negative z-scores were related to the inflammatory process, including systemic lupus erythematosus in B cells and osteoarthritis, in which the RA-related genes Cd72, Cd79a, Ifna, Il33, and Bglap2 were found to be decreased. The bioinformatic algorithm identified four central possible regulators: CEBPA, FOXO1, HIF1A, PPARG, and PPARA. In the analysis of diseases and biofunctions, molecular transport, small molecule biochemistry, and lipid and carbohydrate metabolism tended to increase; conversely, organismal injury and abnormalities, inflammatory response, metabolic diseases, cancer, and endocrine, reproductive, gastrointestinal, skeletal, and muscular system disorders, were decreased by IF

Project description:Various intermittent fasting regimes are popularly being practiced but the scientific understanding for the mechanisms of intermittent fasting remains unclear. Observing the overall transcriptomic changes in specific organs, including heart, may contribute substantially in understanding the diverse effects of intermittent fasting. Our current study further investigate the differential transcriptomic changes in the heart among the different regimes of intermittent fasting as well.

Project description:Transcription factors may orchestrate the health benefits of intermittent fasting through directing the expression of genome. Here, we find intermittent fasting can spin the spatiotemporal profile of transcription factors, and provide an atlas of transcription factors in biological space, time and feeding regimen.

Project description:Intermittent fasting is previously reported to exhibit neuroprotection against experimental ischemic stroke. However, the detailed understanding of protection mechanisms are lacking. By observing the overall transcriptomic changes in each timepoint of ischemic stroke would benefit the understanding of underlying active pathways and mechanisms. Here, we conduct experimental MCAO ischemic stroke on mice exposed to different daily intermittent fasting method to compare not only among the ischemic stroke timepoints but also the efficacy of different intermittent fasting interventions. Our current study presented the transcriptomic changes for the first time in specific timepoints of ischemic stroke as well as under the condition of intermittent fasting. A number of neuroprotective mechanisms-related genes were significantly affected by intermittent fasting conditions in differential manners.

Project description:Rheumatoid arthritis (RA) is a chronic, inflammatory joint disease of unknown etiology and pronounced inter-patient heterogeneity. To characterize RA at the molecular level and to uncover key pathomechanisms, we performed whole-genome gene expression analyses. Synovial tissues from rheumatoid arthritis patients were compared to those from osteoarthritis patients and to normal donors. Keywords: disease state analysis

Project description:Genome-wide DNA methylation level was studied to determine whether Rheumatoid arthritis patients (cases) has methylation differences comparing to normal controls in PBLs. We used Illumina HumanMethylation450 BeadChip array to determine the genome-wide DNA methylation difference in PBLs from Rheumatoid arthritis patients (cases) and normal controls Bisulphite converted DNA from the Rheumatoid arthritis patients (cases) and normal controls were hybridized to the Illumina Illumina HumanMethylation450 BeadChip arrays

Project description:Synovial biopsies were obtained from rheumatoid arthritis (RA) synovium and from subjects without a joint disease to find gene upregulated during RA. The promoters of genes upregulated during RA compared to HC can be used to obtain disease-regulated gene therapy.
