Project description:The objective of the study was to identify microRNAs expressed in the rat soleus muscle and determine if their expression was changed in response to hindlimb suspension. The microRNA expression profile (Sanger miRBase 9.0) of the rat soleus muscle was determined in the following three groups: control (C), hindlimb suspended for 2 days (HS-2) or 7 days (HS-7). Three replicates were performed for each group.

Project description:The electroacupuncture-induced analgesic effect has been used widely to alleviate diverse pains. However, significant individual variations in analgesic effect of EA for both experiments and clinics were reported. According to the sensitivity of the analgesic response to EA stimulation, the subjects could be categorized into high responders (HR) and low responders (LR). However, the molecular mechanism of individual variability in the analgesic response to acupuncture stimulation is still uncertain. This study aims to investigate the potential gene expression in spinal dorsal horn induced by 2Hz/100Hz electroacupuncture in HR and LR rats. Rats were given 2Hz or 100Hz electroacupuncture for 30 min and using cDNA microarrays to compare different gene expression in dorsal horn. Transcriptome profiling analysis found that some co-regulated genes related with electroacupuncture or 2Hz or 100Hz freqencies. These co-regulated genes were plasticity-related by GO analysis. We also found some special regulated genes in HR vs. LR in 2Hz/100Hz electroacupuncture stimulation. These results suggested that neurotransmitter system and cytokine different between HR with LR in 2Hz electroacupuncture. But in 100Hz electroacupunture, there were many different regulated genes related with ribosome between HR with LR, which needs more studies to research the function and may play an important role in HR vs. LR by 100Hz electroacupuncture. Keywords: Transcriptome analysis Rats were exposed to different frequencies (2Hz or 100Hz) electroacupuncture stimlation for 30 min and nociceptive testing and returned to home cages for 1 hours before sacrificed. According to the sensitivity of the analgesic response to 2Hz or 100Hz EA stimulation, the rats divided into four groups: 2Hz-HR group, 2Hz-LR group, 100Hz-HR group and 100Hz-LR group. Subsequently analyzed their dorsal horn transcript profile using cDNA microarrays, the rats were without receiving electroacupuncture as control. The tissue of dorsal horn (DH) of the fifth and sixth lumbar (L5 and L6) of four or five rats were selected for transcript analysis in each group. The five control rats were mixed and labeled with cy5, each rat of experiment groups was labeled with cy3.

Project description:To investigate the molecular mechanisms governing the transition of skeletal muscle from atrophy to compensatory regeneration and hypertrophy, we employed a mouse model involving hindlimb unloading and subsequent reloading, conducting a comprehensive analysis of global gene expression using RNA-sequencing (RNA-seq). Gastrocnemius muscle samples were obtained from three groups: control mice, mice subjected to 10 days of hindlimb unloading-induced muscle atrophy, and mice reintroduced to normal cage activity for 1 day following the unloading period (reloading).

Project description:Disuse-induced muscle atrophy is a common clinical problem observed mainly in older adults, intensive care units patients, or astronauts. Previous studies presented biological sex divergence in progression of disuse-induced atrophy along with differential changes in molecular mechanisms possibly underlying muscle atrophy. The aim of this study was to perform transcriptomic profiling of male and female mice during the onset and progression of unloading disuse-induced atrophy. Male and female mice underwent hindlimb unloading (HU) for 24, 48, 72 and 168h (n=8/group). Muscles were weighed for each cohort and gastrocnemius was used for RNA-sequencing analysis. Females exhibited muscle loss as early as 24h of HU, while males after 168h of HU. In males, pathways related to proteasome degradation were upregulated throughout 168-h HU, while in females these pathways were upregulated up to 72-h HU. Lcn2, a gene contributing to regulation of myogenesis, was upregulated by 6.46–19.86-fold across all time points in females only. A reverse expression of Fosb, a gene related to muscle degeneration, was observed between males (4.27-fold up) and females (4.57-fold down) at 24-h HU. Mitochondrial pathways related to TCA cycle were highly downregulated at 168h of HU in males, while in females this downregulation was less pronounced. Collagen-related pathways were consistently downregulated throughout 168-h HU only in females, suggesting a potential biological sex-specific protective mechanism against disuse-induced fibrosis. In conclusion, females may have protection against HU-induced skeletal muscle mitochondrial degeneration and fibrosis through transcriptional mechanisms, although they may be more vulnerable to HU-induced muscle wasting compared to males.

However, significant individual variations in analgesic effect of EA for both experiments and clinics were reported. According to the sensitivity of the analgesic response to EA stimulation, the subjects could be categorized into high responders (HR) and low responders (NR). However, the molecular mechanism of individual variability in the analgesic response to acupuncture stimulation is still uncertain. This study aims to investigate the potential gene expression in spinal dorsal horn induced by 2Hz/100Hz electroacupuncture in HR and NR rats. Rats were given 2Hz or 100Hz electroacupuncture for 30 min and using cDNA microarrays to compare different gene expression in dorsal horn. Transcriptome profiling analysis found that some co-regulated genes related with electroacupuncture or 2Hz or 100Hz fruqencies. These co-regulated genes were plasticity-related by GO analysis.
