| Sample_molecule_ch1 | total RNA
| Sample_extract_protocol_ch1 | Total RNA was isolated and purified from 100ul of whole blood with the Mouse Ribopure-Blood RNA Isolation Kit (Ambion, Austin, Texas, USA) according to manufacturers instructions.
| Sample_label_ch1 | Biotin
| Sample_label_protocol_ch1 | Three microliter total RNA was used for each sample to obtain linearly amplified labeled cRNA by using GeneChip® One-Cycle Target Labeling kit (Affymetrix, Santa Clara, CA, USA) as described by manufacturer. Briefly, total RNA was used to generate double-stranded cDNA with the T7-oligo (dT) primer. This double-stranded cDNA was used in vitro transcription and biotin labeling steps. Labeled cRNA yield and purity were determined by measuring the absorbance at 260 and 280nm. All the cRNA 260/280 ratios were between 1.9 and 2.1. Quality control of the labeled cRNA products was assessed by performing 1µg labeled cRNA on 2% agarose gel to see similar RNA smear type.
| Sample_hyb_protocol | 15 micrograms of labeled cRNA from whole blood was fragmented, and 10ug was hybridized to Affymetrix Mouse 430 2.0 GeneChip arrays for 18-24h (Affymetrix Inc.). Gene chip was washed and stained with streptavidin-phycoerythrin.
| Sample_scan_protocol | The chip was scanned at 6um resolution with Agilant model G2500A Gene Array scanner. A visual quality control measurement was performed to ensure proper hybridization after each chip was scanned.
| Sample_data_processing | Quality control parameters such as scaling factors used to normalize the chips, average background, and noise were also evaluated. In addition, raw intensities for each probe set were stored in electronic formats by the GeneChip operating system 1.1 (Affymetrix) for GC-RMA analysis in PARTEK software later on.

| Sample_treatment_protocol_ch1 | At the beginning of the experiment mice were divided into two groups, control (room condition) and hypoxic (hypoxic condition). For conditioning, the hypoxic group was exposed to lower levels of hypoxia, in a specially designed and hermetically closed hypoxic chamber, using a special gas mixing system Pegas 4000 MF (Columbus Instruments, Ohio, USA). The oxygen level was decreased from 21% to 8% over a period of 14 days. Animal’s weight and food intake were monitored daily. Food and water were changed daily during the course of the experiment. Before and after the experiments the hematocrit was monitored by taking blood from the tail vein of control and hypoxic animals. After 15 days animals were euthanized using CO2 after whole blood extraction from V. Cava for further analysis.
