Sample GSM870225 Query DataSets for GSM870225
Status Public on Feb 04, 2012
Title 6_Starvation
Sample type SRA
 
Source name young adult animals exposed to complete food deprivation
Organism Caenorhabditis elegans
Characteristics strain: spe-9(hc88)
gender: hermaphrodites
developmental stage: Day 0-1 post-L4 molt (young adult stage. Specifically, 66 hrs after synchronized L1 stage animals were placed bacterial plates)
growth condition: 23°C
stress conditions: Complete food deprivation for 12 hrs
Treatment protocol Animals were exposed to each stress condition, including heat shock (32°C, 6 hrs), Hypoxia (0.01% oxygen, 6 hrs), Oxidation (Juglone 750microM, 6 hrs) and Starvation (complete food deprivation, 12 hrs). Total RNAs were purified from animals just after stress treatment. Also, for recovery from heat shock, animal exposed to heat stress (32°C, 6 hrs) were placed at 23°C for 6 hrs, and then used for RNA isolation. In addition, RNAs were prepared from normally cultured, untreated animals at three time points, 0 hr (baseline), 6 hrs (as controls for heat shock, hypoxia and oxidation) and 12 hrs (as controls for heat shock recovery and starvation) after starting stress exposure.
Growth protocol spe-9(hc88, a sterile mutant) hermaphrodites were maintained for a few generations without starvation at 15°C to collect embryos. After embryos were harvested, they were incubated at 23°C without a food source in M9 buffer for 24 hrs with rotating to arrest their growth at the L1 stage. Synchronized animals were exposed to each stress when they were young adult (Day 0-1 post-L4 molt. More specifically, 66 hrs after synchronized L1 animals were placed on bacterial plates)
Extracted molecule total RNA
Extraction protocol Total RNAs were prepared using the mirVana miRNA Isolation kit (Ambion), and 10 μg of total RNAs were used for cDNA library preparation for small RNAs using the DGE-Small RNA Sample Prep Kit ver. 1.0 (Illumina) according to the manufacturers' instructions.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection size fractionation
Instrument model Illumina Genome Analyzer II
 
Data processing The raw data were aligned to the C. elegans genome (genome build WormBase WS190) using the SOAP program (ver. 1.10 Li, R. et al., Bioinformatics 24: 713-714. 2008) with the following command options: –S 3 –A TCGTATGCCGTCTTCTGCTTGT (maximum 2 base pair mismatches were allowed as a default option). Then, the number of times of each read sequenced was examined.
The *Processed.txt files represent aligned, unique sequencing reads, and their counts observed.
