RELN protein, human

The RELN protein, also known as Reelin, is a large extracellular matrix protein that plays a crucial role in neuronal migration and positioning during brain development.
It is essential for the proper layering and organization of the cerebral cortex, cerebellum, and other brain regions.
The RELN protein acts as a signaling molecule, binding to various cell-surface receptors and triggering intracellular cascades that regulate neuronal positioning and connectivity.
Disruptions in the RELN gene or protein have been implicated in several neurological and psychiatric disorders, including autism spectrum disorder, schizophrenia, and Alzheimer's disease.
Understanding the fuction and regulation of the RELN protein is an active area of research, with applications in neurodevelopmental and neurodegenerative disease studies.

In order to better understand the possible connection between PIDD1 and the brain developmental phenotypes observed in individuals with mutations disrupting PIDD1 function, we used publically available transcriptomic datasets (gene expression microarray and RNAseq) for PIDD1, and co-expression with related genes to explore commonalities in temporaspatial expression. Firstly, we used data from the Genotype-Tissue Expression (GTEx) project to explore gross anatomical gene expression for humans through the GTEx Portal (https://www.gtexportal.org/home/). Secondly, we used Allen Brain Atlas data (www.brainspan.org) to look at temporospatial mRNA expression for human brain from 8 weeks post-conception to 40 years of age, using RNAseq and gene expression microarray23 (link), and from RNAseq data from the PsychEncode dataset24 (link). Adult Human transcriptomic comparisons were performed with the Allen Human Brain Atlas data25 (link). Co-expression analysis of BrainSpan datasets was performed as described previously26 (link) (https://hbaset.msl.ubc.ca/). Thirdly, we used single-cell RNAseq data from fetal and postnatal mouse brains, for which cell types have been classified according to spatial and taxonomical cluster analysis (www.mousebrain.org)27 (link),28 . Data were analyzed from the single-gene perspective (PIDD1/Pidd1 alone), also with PIDDosome interactors (PIDD1/Pidd1+CRADD/Cradd+CASP2/Casp2), or with a gene set of PIDD1 interactors (P gene set: PIDD1, CRADD, CASP2, MADD, FADD) plus genes relevant to lissencephaly (L gene set: RELN, TUBA1A, NDE1, KATNB1, CDK5, ARX, DCX, LPHN1, LPHN2, LPHN3).

To evaluate our annotation methodology, and to compare our GeneRIF results with the traditional OMIM resource in detail, we utilized a well-characterized fifty-gene collection by Homayouni et al. that they used to evaluate semantic indexing of gene functions [20 (link)]. This gene collection includes genes in the reelin signaling pathway of Alzheimer's disease and other genes important in cancer biology and development. We call it Homayouni gene collection from here on. The 5 genes with more than 50 diseases mapped to them (APOE, EGFR, ERBB2, TGFB1 and TP53) were excluded from the test set due to the large number of GeneRIFs requiring manual inspection. This evaluation was done on February 9th, 2006.
Assessing the false positive and false negative error rates for this collection was difficult [24 (link)], so several domain experts were used for scoring the results with all results reviewed by MID (internal medicine physician) who made the final error determination. To determine gene-disease relationships, a false positive was scored only when the disease was identified incorrectly. No effort was made here to assess the appropriateness of the GeneRIF because of the subjective nature of such a process. However for Table 3 estimates were used for calculating precision and recall rates whereby the overall false positive value was corrected to account for false positives arising when a correctly identified disease did not have a relationship to its associated gene as specified in the GeneRIF.

To create the targeting vector for the conditional Reelin knockout mouse line, pJB1 (described in (69 (link))) was used as background vector and murine SV129J ES cell DNA as template DNA to amplify the short homology arm (SA, 1.35 kb), the fragment containing the first exon (EX1, 1.25 kb), and the long homology arm (LA, 9 kb). To incorporate the first loxP site a ClaI and a PvuI restriction site were included in the SA reverse and the EX1 forward primer, respectively. By three-fragment ligation, the (1 (link)) SA (cut with SalI and ClaI) and (2 (link)) EX1 (cut with SalI and PvuI) fragments were combined by a (3 (link)) LoxP coding linker (two annealed oligos with sticky ends for ClaI and PvuI) and cloned between the Neo and HSVTK selection marker genes (XhoI site, compatible ends with SalI) of pJB1. The resulting vector was opened with NotI to insert the 9 kb LA fragment 3'-downstream of the loxP/FRT flanked Neo-cassette. The primers used were: SA_for, 5'- ATCGATGTCGACGGAAGTTTTGCTTCTTCCGGTG-3' (SalI); SA_rev, 5'-CAATCGATGTTGTTTGTCTACGCCGGCTGCAAC-3' (ClaI); EX1_for, 5'-CCTTCTCGCGATCGCGCGTCCTCGCAGAACGGGCAGCC-3' (PvuI); EX1_rev, 5'-GCGGCCGCGTCGACTGGGCAGCCACCGACCAAAGTGCTC -3' (SalI); LA_for, 5'-TGTTGCGGCCGCGGCGGCCAGTTAAAAGTTCCCGCTG-3' (NotI); LA_rev, 5'-GTCGACGCGGCCGCTTCCATAAAAGGGAAGAGCAAGATG-3' (NotI). The oligos used were: LoxP_for, 5'-CGATAACTTCGTATAGCATACATTATACGAAGTTATAT-3'; LoxP_rev, 5'-CGATATAACTTCGTATAATGTATGCTATACGAAGTTATCGAT-3'. The final construct containing the SA-LoxP-EX1-LoxP-Neo-LoxP-LA-HSVTK cassette was linearized and electroporated into SV129J ES cells. Gene-targeting-positive ES cells (PCR screen) were injected into C57Bl/6J blastocysts resulting in chimeric mice. The chimeras were crossed to C57Bl/6J mice, resulting in Relnfl/wt mice, verified by PCR and Southern blot. Heterozygous animals were backcrossed to Meox-Cre on the BL6 background to yield germline mutant reeler mice. Heterozygous animals were also backcrossed to CAG-CreERT2 mice to obtain homozygous Relnfl/fl; CAG-Cre mice. These were again backcrossed to Tg2576 mice and offspring used in the experiments were brother/sister crossed CAG-Cre hemizygous and Tg2576 hemizygous mice. To ensure a minimal effect on the behavioral results we have found, all animals that were compared were brother/sister crosses that only differ by the absence or presence of Cre recombinase. Moreover, discovering a robust response like the one discussed here in a mixed background, as opposed to an inbred one, further strengthens the validity of the conclusions, rather than diminishing them. Most importantly perhaps, it further supports the applicability of the results to the even more genetically heterogeneous human population.

For analyzing the molecular expression profiles and layering of fate-mapped interneurons, the somatosensory barrel cortex in three P21 brains was analyzed using immunohistochemistry (E12.5: n=1243, E14.5: n=3005, E16.5: n=4141, E18.5: n=2528). Immunohistochemistry on 12μm thickness cryosections was performed as described previously (Miyoshi et al., 2007 (link)). In order to assess the size of the four non-overlapping interneuron populations (Figure 4B), we have carried out either PV/VIP/EGFP or SST/Reelin/EGFP triple stainings on P21 brains from mice with Dlx5/6-Flpe and RCE:FRT alleles. A total of 1604 EGFP-expressing cells from three brains were analyzed.
Antibodies were used at the following concentrations: mouse anti-Nkx2.1 (TTF-1) (1:200; PROGEN), rabbit anti-Lhx6 (1:1000; a gift from Dr. Vassilis Pachnis), rabbit anti-Pax6 (1:1000; Covance), mouse anti-Mash1 (1:1000; BD Pharmingen), mouse anti-Ki67 (1:1000; BD Pharmingen), guinea pig anti-Six3 (1:1000; Covance), mouse anti-CoupTFII (1:500; Perseus Proteomics), rabbit anti-GFP (1:2000; Molecular Probes), rat anti-GFP (1:2000; Nacalai Tesque), goat anti-GFP (1:2000; Rockland), mouse anti-Parvalbumin (1:1000; Sigma), guinea pig anti-Parvalbumin (1:1000; a gift from Dr. Baimbridge, University of British Columbia) rat anti-somatostatin (1:500; Chemicon), rabbit anti-somatostatin (1:1000; Chemicon), rabbit anti-Neuropeptide Y (1:500; Incstar), rabbit anti-Vasoactive intestinal polypeptide (1:500; Incstar), mouse anti-Calretinin (1:1500; Chemicon), rabbit anti-Calretinin (1:1500; Chemicon), mouse anti-Reelin (CR50) (1:500; MBL). Secondary antibodies conjugated with Alexa fluoro dyes 488, 594 or 680 (Molecular Probes) or AMCA (Jackson Immunoresearch) raised from the same host used for blocking serum were chosen for signal visualization. Fluorescent images were captured using a cooled-CCD camera (Princeton Scientific Instruments, NJ) using Metamorph software (Universal imaging, Dwoningtown, Pennsylvania). One-way ANOVA with Bonferroni post hoc test was used to detect differences in marker immunolabeling between cell cohorts arising from different developmental time points.
