Sample GSM820710 Query DataSets for GSM820710
Status Public on Oct 22, 2011
Title immature_bone_marrow_MBs_and_PMs_AO.B3
Sample type RNA
Source name Bone marrow neutrophil precursors
Organism Homo sapiens
Characteristics maturation stage: myeloblasts and promyelocytes
Extracted molecule total RNA
Extraction protocol All cell populations were isolated on a PercollTM density gradient followed by immunomagnetic depletion as described in Bjerregaard MD, Jurlander J, Klausen P, Borregaard N, Cowland JB: The in vivo profile of transcription factors during neutrophil differentiation in human bone marrow. Blood 2003, 101: 4322-4332.
Label Hy3
Label protocol Total RNA extracted from BM and PB cell populations was labeled with the miRCURYTM Array Labeling kit (Exiqon, Vedbæk, Denmark) and hybridized to miRCURYTM LNA microRNA Arrays (Exiqon) in a Tecan HS400 hybridization station (Tecan Nordic AB, Brøndby, Denmark). Labeling with the fluorescent dyes Hy3 and Hy5 and preparation of wash buffers were done according to the manufacturer’s instructions (Exiqon)
Hybridization protocol Slides were placed in the hybridization chambers and primed by injecting hybridization buffer into each chamber. Finally, the target preparations were injected and incubated for 16 hours at 60ºC with medium agitation. After hybridization, slides were washed, soaked in wash buffers, and dried as recommended by the manufacturer (Exiqon). Slides were removed from the hybridization station and kept in the dark in a nitrogen sphere until scanning.
Scan protocol Slides were scanned in an Agilent DNA microarray scanner (G2565BA). Image analysis was performed using the Genepix® Pro Software (version 6.1.2; Molecular Devices, Philadelphia, USA). A gene array list(GAL) file ( GAL file: 2-11-2007) with miRNA annotations according to miRBase (version 10) was applied to annotate features and generate a Genepix Results (GPR) File for each image, with median foreground and mean background values for each spot.

Biological replicate 3a
Data processing GPR files were loaded into the R (version 2.0.1) software environment (Gentleman R, Isaka R: R: A Language for Data Analysis and Graphics. Journal of Computational and Graphical Statistics 1996, 5: 299-314) using the Limma software package (Smyth, G. K. (2005). Limma: linear models for microarray data. In: Bioinformatics and Computational Biology Solutions using R and Bioconductor, R. Gentleman, V. Carey, S. Dudoit, R. Irizarry, W. Huber (eds.), Springer, New York, pages 397–420). Normalization of fluorescence signals between all samples was performed in R (version 2.0.1) using qspline (Workman C, Jensen LJ, Jarmer H, Berka R, Gautier L, Nielser HB et al.: A new non-linear normalization method for reducing variability in DNA microarray experiments. Genome Biol 2002, 3(9):research0048) prior to all statistical analysis.
