<Blockquote>
<P> HEI Optic Nerve Crush (ONC) – Control Retina Illumina V6.2 (April 2010) RankInv ** was normalized and scaled by William E. Orr and uploaded by Arthur Centeno and Xiaodong Zhou on February 1, 2011. This data set consists of BXD strains, C57BL/6J, DBA/2J, both reciprocal F1s, and BALB/cByJ. The data base was constructed by subtacting the normal expression values from the values from the same strain that were generated from retinas 2 days after optic nerve crush.
<P> This is rank invariant data with 2z+8 stabilization, but without special correction for batch effects. The data includes the mean of four samples per strain. Values in expression range from 0000 to 0000 (0000 units), a nominal range of 0000-fold.
<P>The lowest level of expression is 0000 for ILMN_000 (0000) from HEI Retina Illumina V6.2 (April 2010) RankInv **. Lowest single data about 5.842.
<P>The highest level of expression is 0000 for ILMN_0000 (000). Highest single value is about 18.934.

<P class="subtitle">About the cases used to generate this set of data:</P>
<Blockquote>
<P>Almost all animals are young adults between 60 and 90 days of age (Table 1, minimum age is 48 and maximum age is 118 days). We measured expression in conventional inbred strains, BXD recombinant inbred (RI) strains, and reciprocal F1s between C57BL/6J and DBA/2J.
<Blockquote>
<b>BXD strains:</b> <P><LI>The first 32 of these strains are from the Taylor series of BXD strains generated at the Jackson Laboratory by Benjamin A. Taylor. BXD1 through BXD32 were started in the late 1970s, whereas BXD33 through 42 were started in the 1990s.
<p>
<LI>In 2004, BXD24/TyJ developed a spontaneous mutation, rd16 which resulted in retinal degeneration and was renamed BXD24b/TyJ (BXD24 in this database). The strain, BXD24a, was cryo-recovered in 2004 from 1988 embryo stocks (F80) and does not exhibit retinal degeneration. In 2009, BXD24b was renamed BXD24/TyJ-Cep290rd16/J by JAX Labs to reflect the discovery of the genetic basis of the mutation. At the same time BXD24a was then referred to just as BXD24/TyJ by Jax Labs, but still called BXD24a in this dataset.
<p>
<LI>The other 36 BXD strains (BXD43 and higher) were bred by Lu Lu, Jeremy Peirce, Lee M. Silver, and Robert W. Williams starting in 1997 using B6D2 generation 10 advanced intercross progeny. This modified breeding protocol doubles the number of recombinations per BXD strain and improves mapping resolution (<a href="http://www.biomedcentral.com/1471-2156/5/7" target="_blank" class="fs14">Peirce et al. 2004</a>). All of the Taylor series of BXD strains and many of the new BXD strains are available from the Jackson Laboratory. All of the new BXD strains (BXD43 and higher) are also available directly from <A HREF="mailto:lulu@nb.uthsc.edu" target="_blank" class="fs14">Lu Lu</A> and colleagues at the University of Tennessee Health Science Center in Memphis, TN, USA. BXD24/TyJ is now known as BXD24b/TyJ and has nearly complete retinal degeneration. BXD24a/TyJ, a 1988 F80 inbred stock that has been rederived from cryogenic storage, does not have retinal degeneration (stock number 005243) and is an ideal coisogenic control, but is not included in the HEI data set.

<P class="subtitle">About the tissue used to generate this set of data:</P>
<Blockquote>
<P><B>Tissue preparation protocol</B>. Animal were killed by rapid cervical dislocation. Retinas were removed immediately and placed in RNA<I>later</I> at room temperature. Two retinas from one mouse were stored in a single tube.
<p><b>Dissecting and preparing eyes for RNA extraction</b>
<P>
<p>Retinas for RNA extraction were placed in RNA STAT-60 (Tel-Test Inc.) and processed per manufacturer’s instructions (in brief form below).
Total RNA was extracted with RNA STAT-60 (Tel-Test Inc.) according to the manufacturer's instructions. Briefly we:
<P><ul>
<li>Homogenize tissue samples in the RNA STAT-60 (1 ml/50 to 100 mg tissue via syringe)
<li>Allow the homogenate to stand for 5-10 min at room temperature
<li>Add 0.2 ml of chloroform per 1 ml RNA STAT-60
<li>Mix the sample vigorously for 15 sec and let the sample incubate at room temperature for 5-10 min
<li>Centrifuge at 12,000 g for 1 hr at 4°C
<li>Transfer the aqueous phase to a clean centrifuge tube
<li>Add 0.5 ml of isopropanol per 1 ml RNA STAT-60
<li>Vortex and incubate the sample at -20°C for 1 hr or overnight
<li>Centrifuge at 12,000 g for 1 hr
<li>Remove the supernatant and wash the RNA pellet with 75% ethanol
<li>Remove ethanol, let air dry (5-10 min)
<li>Dissolve the pellet in 50 μl of nuclease free water.
<p>
</ul>
<p><b>Sample Processing:</b> Drs. Natalie E. Freeman-Anderson and Justin P. Templeton extracted the retinas from the mice and Dr. Natalie Freeman-Anderson processed all samples in the HEI Vision Core Facility. The tissue was homogenized and extracted according to the RNA-Stat-60 protocol as described by the manufacturer (Tel-Test, Friendswood, TX) listed above. The quality and purity of RNA was assessed using an Agilent Bioanalyzer 2100 system. The RNA from each sample was processed with the Illumina TotalPrep RNA Amplification Kit (Ambion, Austin, TX) to produce labeled cRNA. The cRNA for each sample was then hybridized to an Illumina Sentrix® Mouse-6-V2 BeadChip (Illumina, San Diego, CA)
<p>
<P>
<p>Quality control analysis of the raw image data was performed using the Illumina BeadStudio software. MIAME standards were used for all microarray data. Rank invariant normalization with BeadStudio software was used to calculate the data. Once this data was collected, the data was globally normalized across all samples using the formula 2 (z-score of log2 [intensity]) + 8.
<P><B>Replication, sex, and sample balance:</B> Our goal was to obtain data for independent biological sample pools from both sexes for most lines of mice. The four batches of arrays included in this final data set, collectively represent a reasonably well-balanced sample of males and females, in general without within-strain-by-sex replication.
