A recent study reported that OLIG2 had a significant association with schizophrenia in the UK population. We genotyped three variants scattered among the genomic region of OLIG2, namely rs1005573, rs762178 and rs1059004 in a sample consisting of 329 schizophrenia patients and 288 controls. The results provide further evidence that the SNP rs762178 in OLIG2(More)
Recently, several researches based on expression analysis, genetic linkage and association studies have suggested that the regulator of G-protein signaling 4 (RGS4) might be a schizophrenia susceptibility gene. However, these linkage and association studies have been conducted using different ethnic samples, and have therefore tended to produce inconsistent(More)
Nitric oxide (NO) plays an important role in the dopaminergic and serotonergic system as the second messenger of the NMDA receptor and has possible roles in neurotransmission, neurosecretion, synaptic plasticity, and tissue injury in many neurological disorders, including schizophrenia. There is also genetic evidence to support the human NOS1 (neuronal(More)
Heterozygous missense mutations in IHH result in Brachydactyly type A1 (BDA1; OMIM 112500), a condition characterized by the shortening of digits due to hypoplasia/aplasia of the middle phalanx. Indian Hedgehog signaling regulates the proliferation and differentiation of chondrocytes and is essential for endochondral bone formation. Analyses of activated(More)
The generation of hydrogen from water using sunlight could potentially form the basis of a clean and renewable source of energy. Various water-splitting methods have been investigated previously, but the use of photocatalysts to split water into stoichiometric amounts of H2 and O2 (overall water splitting) without the use of external bias or sacrificial(More)
Results from a number of molecular and pharmacological studies suggest that the phosphatidylinositol-4-phosphate 5-kinase IIalpha (PIP5K2A) gene may be involved in the development of schizophrenia. A recent family-based transmission disequilibrium test in the German and Israeli populations found that four single nucleotide polymorphisms, rs1417374,(More)
Wnt proteins are diffusible morphogens that play multiple roles during vertebrate limb development. However, the complexity of Wnt signaling cascades and their overlapping expression prevent us from dissecting their function in limb patterning and tissue morphogenesis. Depletion of the Wntless (Wls) gene, which is required for the secretion of various Wnts,(More)
Parietal foramina [PFM], inherited usually in an autosomal dominant mode, is an extremely rare developmental defect characterized by a symmetrical, oval hole in the parietal bone. It can be present as either an isolated or a syndromic feature. PFM types 1 and 2 (PFM1 and PFM2) have been found to be caused by mutations in the MSX2 and ALX4 genes, located to(More)
Schizophrenia is a complex mental disease caused by a combination of serial alterations in genetic and environmental factors. Although the brain is usually considered as the most relevant organ in schizophrenia, accumulated evidence suggests that peripheral tissues also contribute to this disease. In particular, abnormalities of the immune system have been(More)
