Extracted molecule |
total RNA |
Extraction protocol |
Total RNA was extracted from frozen samples stored in TRIzol (Invitrogen, Carlsbad, Calif.) and processed for microarray analysis according to the microarray manufacturer’s protocol (Affymetrix, Santa Clara, Calif.)
|
Label |
biotin
|
Label protocol |
According to standard affymetrix protocol: • 10ul Purified cDNA10ul • DEPC H2O • 4ul 10x IVT Labeling Buffer • 12ul IVT Labeling NTP mix • 4ul IVT Labeling Enzyme mix - Incubate at 37C 16 hour in an incubating oven or thermal cycler with heated lid to avoid condensation. - Purify labeled cRNA generated from either IVT labeling reaction using RNeasy RNA Purification Mini kit (Qiagen) using the RNA Cleanup Protocol according to manufacturers instructions. - Quantitate Biotin labeled cRNA using 260nm/280nm spectrophotometric assay.

Hybridization protocol |
Samples were hybridized using Affymetrix hybridization kit materials: • Heat the hybridization cocktail to 99°C for 5 minutes in a heat block • Incubate the probe array filled with Pre-Hybridization Mix at 45°C for 10 minutes with rotation • Transfer the hybridization cocktail that has been heated at 99°C, to a 45°C heat block for 5 minutes • Spin the hybridization cocktail at maximum speed in a microcentrifuge for 5 minutes to collect any insoluble material from the hybridization mixture • Remove the array from the hybridization oven. Vent the array with a clean pipette tip and extract the Pre-Hybridization Mix from the array with a micropipettor. Refill the array with the appropriate volume of the clarified hybridization cocktail, avoiding any insoluble matter at the bottom of the tube • Place probe array into the hybridization oven, set to 45°C • To avoid stress to the motor, load probe arrays in a balanced configuration around the axis. Rotate at 60 rpm • Hybridize for 16 hours • During the latter part of the 16-hour hybridization, proceed to the GeneChip® Expression Wash, Stain and Scan User Manual, P/N 702731, to prepare reagents for the washing and staining steps required immediately after completion of hybridization

Description |
dissected from frozen coronal blocks ~2–3 cm caudal to the temporal pole
|
Data processing |
Probeset signals (i.e., transcript levels) were extracted with the Affymetrix GCOS software. For statistical analysis, log2- transformed probeset signal intensities were extracted and normalized with the robust multiarray average (GC-RMA) algorithm
