26wk_Cancellous_Loaded Limb_5d2_Animal5dAC |
| Sample type |
SRA |
| |
|
| Source name |
Cancellous
|
| Organism |
Mus musculus |
| Characteristics |
sample number: A02
tissue: Cancellous
loaded: L
animal number: 5dAC
timepoint: 5d2
age: Adult
genotype: C57Bl6J
treatment: Loaded_5d2
|
| Treatment protocol |
10- and 26-week-old female C57Bl/6J were subjected to in vivo mechanical loading of the left tibia (9N peak load at 4 Hz for 1200 cycles per day). Mice were euthanized by cervical dislocation at 1-hour, 3-hours, or 24-hours following the completion of one bout of loading. To evaluate long term time points, a final group received 5 consecutive days of loading with euthanasia on the eighth day following the first loading session

| Extracted molecule |
total RNA |
| Extraction protocol |
Cancellous bone was separated from the cortical shell. The cortical bone was segmented into three sections: metaphyseal cortex, proximal diaphysis, and mid-diaphysis,and the metaphyseal cortex and mid-diaphysis were then analyzed. All tissues were flash frozen in liquid nitrogen. Samples were pulverized and RNA isolated using a phenol-chloroform extraction followed by the RNeasy kit (Qiagen).
RNA libraries were prepared for 3' mRNA-seq

| Data processing |
Sequence reads were trimmed for adaptor sequence. 12bp were trimmed from the 5' end for quality assurance.
Trimmed sequence reads were mapped to mm10 using STAR (parameters- outFilterMismatchNmax: 2 - outFilterMultimapNmax: 1)
Fastqc was run for all files and only samples with high quality from both fastqc & RQN were included for analysis
Each sample contained over 1 million reads. Genes with less than 3 counts per million were not included for analysis.
Normalized gene counts were calculated in DESeq2 with Trimmed Mean of M-values correction
Assembly: mm10
Supplementary files format and content: .xlsx file with normalized gene counts and experimental conditions for each samle
