MiRNA expression signatures in heart tissues of mice simulating posttraumatic stress disorder (PTSD) [Study2]

ABSTRACT: Using a PTSD mouse model, we investigated the longitudinal transcriptomic changes in heart tissues after the exposure to stress through intimidation We designed our time-course study (Study II) with three experimental conditions where we varied the length of time that subservient mice were exposed to aggressor mice with the same length of rest time after the exposure (1day). The conditions included were 1day-exposure (T1R1), 2day-exposure (T2R1) and 3day-exposure (T3R1). We designed our initial study (Study I) with four experimental conditions where we varied the length of time that subservient mice were exposed to aggressor mice and the length of rest time after the exposure. The conditions included were short exposure-short rest (T5R1-T indicates the number of days of trauma exposure; R indicates the number of days of rest after exposure), short exposure-long rest (T5R10), long exposure-short rest (T10R1) and long exposure-long rest (T10R42)

Liver Transcriptomics data from mouse model with Features of Post-traumatic Stress Disorder

Project description:We have used a social defeat (SD) mouse model of post-traumatic stress disorder (PTSD) that is based on a brief exposure of a mouse to the aggressor mice for either 5 d or 10 d stress periods. Mice simulating aspects of posttraumatic stress disorder exhibit behavioral changes, body weight gain, increased body temperature, and inflammatory and fibrotic histopathologies and transcriptomic changes of heart tissue. Liver tissue of these mice was subjected to mRNA analysis. Transcriptomic analysis of liver indicated chronic toxicities and metabolic alterations in aggressor-exposed mice that possibly contributed to the persistent metabolic disturbance Two-condition experiment, C57BL6/J mice Biological replicates: 4-6 control replicates, 5-6 stressed replicates.

Transcriptome profiling of spleen, blood and hemi-brain of social stressed C57B6 mice exhibiting PTSD like features

Project description:Social stress mouse models were used to simulate human post-traumatic stress disorder (PTSD). C57B/6 mice exposed to SJL aggressor mice exhibited behaviors accepted as PTSD-in-mouse phenotype: 'frozen' motion, aggressor's barrier avoidance, startled jumping, and retarded locomotion. Transcripts in spleen, blood and hemi-brain of stressed and control C57B/6 mice were analyzed using Agilent's mouse genome-wide arrays. C57B6 mice were exposed to SJL aggressor mice for periods of 5 days and 10 days (6 hours each day) to induce anxiety/stress which parallels to PTSD in human. Organs, blood and brain regions were collected after 24 hours and 1.5 week of post 5 days social defeat period; and 24 hour and 6 weeks post 10 days social stress period.

Brain transcriptome profiles in mouse model simulating features of post-traumatic stress disorder

Project description:Social stress mouse models were used to simulate human post-traumatic stress disorder (PTSD). C57B/6 mice exposed to SJL aggressor mice exhibited behaviors accepted as PTSD-in-mouse phenotype: 'frozen' motion, aggressor’s barrier avoidance, startled jumping, and retarded locomotion. Transcripts in hippocampus, amygdala, medial prefrontal cortex, ventral striatum (nucleus acumbens), septal region, corpus striatum, hemi-brain, blood, spleen and heart of stressed and control C57B/6 mice were analyzed using Agilent’s mouse genome-wide arrays. C57B6 mice were exposed to SJL aggressor mice for periods of 5 days and 10days (6 hours each day) to induce anxiety/stress which parallels to PTSD in human Organs, blood and brain regions were collected after 24 hours and 1.5 week of post 5 days social defeat period; and 24 hour and 6 weeks post 10 days social stress period.

Human plasma: circulating microRNA after acute resistance exercise

Project description:Profiling of circulating miRNAs before, 60 mins, 1day and 3 days after an acute resistance exercise. Three subjects performed an acute resistance exercise. The resistance exercise consisted of two consecutive exercises (bench press and bilateral leg press), consisting of five sets of 10 repetitions at 70% of 1 RM. The subjects were allowed to rest for 1 min between each set and exercise. The subjects were instructed to lift and lower the load at a constant velocity, taking about 2 s for each repetition. If the load became too heavy, the subject was assisted. The range of motion in each exercise was from 90° to 0° (0° at full extension). Blood samples were taken before, 60 mins, 1day and 3days after the exercise.

Transcriptomic analysis of mouse lung tissue exposed to two multiwalled carbon nanotubes (NRCWE-26 and NM-401)

Project description:Multi-walled carbon nanotubes (MWCNTs) are extensively produced and used in composite materials and electronic applications, thus increasing risk of worker and consumer exposure. MWCNTs are an inhomogeneous group of nanomaterials that exist in various lengths, shapes and with different metal compositions, which makes hazard evaluation difficult. However, several studies suggest that length plays an important role in the toxicity induced by MWCNTs. How the length influences toxicity at the molecular level is yet to be characterized. We used high-content genomics tools to compare pulmonary responses after exposure to a short, entangled MWCNT to the pulmonary responses after exposure to a long, stiffer MWCNT at the global transcriptomic level. Female C57BL/6 mice were exposed by single intratracheal instillation to 18, 54 or 162 µg/mouse of a short MWCNT (NRCWE-26 (NC-7000), 847±102 nm in length) or long MWCNT (NM-401 (CP-0006-SG), 4048±366 nm in length). Lung tissues were harvested 24 h, 3 d and 28 d after exposure.
