RNA-Seq analysis implicates dysregulation of the immune system in schizophrenia
Background While genome-wide association studies identified some promising candidates for schizophrenia, the majority of risk genes remained unknown. We were interested in testing whether integration gene expression and other functional information could facilitate the identification of susceptibility genes and related biological pathways.
Results We conducted high throughput sequencing analyses to evaluate mRNA expression in blood samples isolated from 3 schizophrenia patients and 3 healthy controls. We also conducted pooled sequencing of 10 schizophrenic patients and matched controls. Differentially expressed genes were identified by t-test. In the individually sequenced dataset, we identified 198 genes differentially expressed between cases and controls, of them 19 had been verified by the pooled sequencing dataset and 21 reached nominal significance in gene-based association analyses of a genome wide association dataset. Pathway analysis of these differentially expressed genes revealed that they were highly enriched in the immune related pathways. Two genes, S100A8 and TYROBP, had consistent changes in expression in both individual and pooled sequencing datasets and were nominally significant in gene-based association analysis.
Conclusions Integration of gene expression and pathway analyses with genome-wide association may be an efficient approach to identify risk genes for schizophrenia
Direct Mediation and Metastable Supersymmetry Breaking for SO(10)
We examine a metastable Macroscopic SO(N) SQCD model of
Intriligator, Seiberg and Shih (ISS). We introduce various baryon and meson
deformations, including multitrace operators and explore embedding an SO(10)
parent of the standard model into two weakly gauged flavour sectors. Direct
fundamental messengers and the symmetric pseudo-modulus messenger mediate SUSY
breaking to the MSSM. Gaugino and sfermion masses are computed and compared for
each deformation type. We also explore reducing the rank of the magnetic quark
matrix of the ISS model and find an additional fundamental messenger.Comment: 43 pages, Latex. Version to appear in JHEP

A Gene Responsible for Cavernous Malformations of the Brain Maps to Chromosome 7Q
Cavernous malformations of the brain are vascular lesions which are present in up to 0.4% of all individuals and which are often accompanied by seizures, migraine, hemorrhage and other neurologic problems. Using linkage analysis and a set of short tandem repeat polymorphisms, a gene responsible for cavernous malformations in a large Hispanic kindred was mapped to the q11-q22 region of chromosome 7. A maximum pairwise lod score of 4.2 was obtained at zero recombination with marker PY5-18 at locus D7S804. Lod scores in excess of 3.0 were obtained with four additional markers closely linked to PY5-18. A broad chromosome 7q haplotype of 33 cM length on the sex average map was shared by all affected individuals indicating that the gene lies between loci D7S502 and D7S479. / 1995 Oxford University Press
