Sample GSM175263 Query DataSets for GSM175263
Status Public on May 02, 2007
Title P-LI-18-2-745
Sample type RNA
 
Channel 1
Source name liver (18 h after injected with lung cancer cells)
Organism Mus musculus
Characteristics Liver from male C57BL/6 mice 18 h after s.c. injection of LL/2(LLC1) lung tumor cells
Treatment protocol Eight week old C57Bl/6 male mice were injected s.c. with 1E6 LL/2(LLC1) lung tumor cells in 300 ul PBS and sacrifice by decapitation after 18 h
Growth protocol Mice were housed in HEPA filtered air racks (Tecniplast, Italy) with food and water ad libitum
Extracted molecule total RNA
Extraction protocol Total RNA was extracted using TRIzol Reagent (Invitrogen)
Label Cy3
Label protocol RNA was reversed transcribed using Superscript II RT (Invitrogen) with oligo dT primers and random primers, both in the presence of aa-dUTP (Sigma). The cDNA was labeled with Cy3 or Cy5 dyes (Amersham), resuspended in DMSO, and incubated for 1 hr at room temperature in the dark. The probes were purified using the SNAP Gel Purification Kit (Invitrogen) following manufacturer instructions with the following modification: at the initial step, 500 ul of loading buffer (2.25 M guanidinium HCl in 70% isopropanol) were added to the sample, placed in a SNAP column and incubated for 4 min before the first centrifugation
 
Channel 2
Source name liver (control)
Organism Mus musculus
Characteristics Liver from male C57Bl/6 mice 18 h after s.c. injection of PBS
Treatment protocol Eight week old C57Bl/6 male mice were injected s.c. with 300 ul PBS and sacrifice by decapitation after 18 h
Growth protocol Mice were housed in HEPA filtered air racks (Tecniplast, Italy) with food and water ad libitum
Extracted molecule total RNA
Extraction protocol Total RNA was extracted using TRIzol Reagent (Invitrogen)
Label Cy5
Label protocol RNA was reversed transcribed using Superscript II RT (Invitrogen) with oligo dT primers and random primers, both in the presence of aa-dUTP (Sigma). The cDNA was labeled with Cy3 or Cy5 dyes (Amersham), resuspended in DMSO, and incubated for 1 hr at room temperature in the dark.

Hybridization protocol Slides were prehybridised at 42°C in 2X SSC, 0.1% SDS, 1% BSA. Labeled probes were mixed with hybridization buffer containing 30% formamide and hybridized overnight at 42°C
Scan protocol Images were obtained with a VersArray ChipReader system (BioRad) at 10 um resolution and 16bit depth. Each slide was scanned three times, each time with a 5% increment in the sensitivity of the scanner. The data integration for multipole scanning were calculated by M = log2(cy3 / cy2) and A = 0.5 * log2(cy2 * cy3) values for all the possible combinations between channels among the three scannings. Quality score for each couple of channels was calculated as QS = min(QScy2, QScy3). The resulting 9 sets of A and M values were averaged using the QS as weights to obtain the integrated A and M sets.
Description Liver of male C57Bl/6 mice
Data processing Data was log2 transformed and normalizaed with an intensity- and location-dependent loess fit
