Gene expression changes in blood RNA after swimming ...
Trihalomethanes (THM) are a class of disinfection by-products in chlorinated waters linked to deleterious health effects in humans although biological mechanisms are unclear. We aimed to study short-term changes in blood gene expression of adult recreational swimmers associated with physical activity and THM exposure.Adult volunteers (18-50 years, non-smokers, non-asthmatics) swam 40 minutes in an indoor chlorinated pool in Barcelona. Blood samples and THM measurements in exhaled breath were ...

Systems-based analyses of brain regions functionally...
Detailed analysis of disease-affected tissue provides insight into molecular mechanisms contributing to pathogenesis. Substantia nigra, striatum and cortex are functionally connected with increasing degreesof alpha-synuclein pathology in Parkinson's disease. Functional and causal pathway analysis of gene expression and proteomic alterations in these three regions revealed pathways that correlated with depositionof alpha-synuclein. Microarray and RNAseq experiments revealed previously unidenti...

Intrinsic self-DNA triggers inflammatory disease dep...
Inflammatory diseases such as Aicardi-Goutieres Syndrome (AGS) and severe systemic lupus erythematosus (SLE) are generally lethal disorders that have been traced to defects in the exonuclease Trex1 (DNAseIII). Mice lacking Trex1 similarly die at an early age through comparable symptoms, including inflammatory myocarditis, through chronic activation of the STING (stimulator of interferon genes) pathway. Here we demonstrate that phagocytes rather than myocytes are predominantly responsible for ...

Gene coexpression network and community detection an...
Prolonged febrile seizures history (FH) in early childhood is associated with refractory temporal lobe epilepsy (RTLE). FH-RTLE patients may have early (E, before 4 YOA) or late (L, mid-adolescence, early adult life) disease onset. In order to investigate molecular mechanisms underlying E and L forms we compared differentially expressed (DE) and complete (CO) transcriptional networks from hippocampal CA3 explants obtained from E and L patients.

Characteristic DNA methylation profiles in periphera...
Epigenetic changes including DNA methylation caused by environmental exposures may contribute to the heterogeneous inflammatory response in asthma. Here we investigate alterations in DNA methylation of purified blood monocytes that are associated with inflammatory phenotypes of asthma.

DNA methylation in systemic lupus erythematosus patients
To screen specific DNA methylation markers in systemic lupus erythematosus (SLE) patient's blood DNA, whole-blood DNAs from 6 female SLE patients and 6 female controls were analyzed by methylation microarray.

Expression changes in mouse brains following nicotin...
Nicotine, acting through the neuronal nicotinic acetylcholine receptors (nAChR), can induce seizures in mice. We aimed to study brain transcriptional response to seizure and to identify genes whose expression is altered after nicotine-induced seizures. Whole brains of untreated mice were compared to brains one hour after seizure activity, using Affymetrix U74Av2 microaarays. Experimental groups included wild-type mice and both nicotine-induced seizures sensitive and resistant nAChR mutant mic...
