Common variants conferring risk of schizophrenia

2009

Schizophrenia is a complex disorder, caused by both genetic and environmental factors and their interactions. Research on pathogenesis has traditionally focused on neurotransmitter systems in the brain, particularly those involving dopamine. Schizophrenia has been considered a separate disease for over a century, but in the absence of clear biological markers, diagnosis has historically been based on signs and symptoms. A fundamental message emerging from genome-wide association studies of copy number variations (CNVs) associated with the disease is that its genetic basis does not necessarily conform to classical nosological disease boundaries. Certain CNVs confer not only high relative ris…

DECORIN EFFECTS ON PROTEOMIC PROFILING OF BREAST CANCER CELLS: AN UPDATED STUDY

2015

The malignant carcinomas are characterized by several capabilities acquired by the neoplastic cells, among which the ability to invade the extracellular matrix (ECM) and to establish a crosstalk with several ECM components. Under this respect, the extracellular microenvironment is an entity extraordinarily rich of information with opposite signals. Our group has long undertaken the study of the effects of ECM molecules on the behavior of cancer cells in vitro. Among the studied molecules, the decorin was found to exert a non-permissive effect on the growth and motility of the transfected tumor cells. The decorin, belongs to the family of small leucine-rich proteoglycans (SLRP) and is involv…

The malignant carcinomas are characterized by several capabilities acquired by the neoplastic cells among which the ability to invade the extracellular matrix (ECM) and to establish a crosstalk with several ECM components. Under this respect the extracellular microenvironment is an entity extraordinarily rich of information with opposite signals. Our group has long undertaken the study of the effects of ECM molecules on the behavior of cancer cells in vitro. Among the studied molecules the decorin was found to exert a non-permissive effect on the growth and motility of the transfected tumor cells. The decorin belongs to the family of small leucine-rich proteoglycans (SLRP) and is involved physiologically in the fibrillogenesis of collagen. In the last few year a new anti-oncogenic role has been proposed for decorin1. This study aimed to implement the knowledge on the effects of ectopic decorin on breast cancer cells using as a reference point the results already achieved by our research group2 on the experimental model format. By breast cancer cell line 8701-BC and its transfected clone DEC-C2. The extension of the proteomic analysis combined with the mass spectrometry allowed to triplicate the number of identified proteins in our model. Among the newly identified proteins were members of the classes of metabolic enzymes S100 family and cell motility proteins which revealed a net decrease in the decorin transfected cells. Of considerable importance is the observation that these classes of proteins are the most involved in metastatic progression. These results confirm and reinforce the anti-oncogenic role hypothesized for decorin. The work was co-funded by the Italian 5x1000 to COBS.DECORIN

Unusual activity pattern of leucine aminopeptidase inhibitors based on phosphorus containing derivatives of methionine and norleucine

2010

Ligands containing bulky aliphatic P1 residues exhibit a high affinity towards cytosolic leucine aminopeptidase, a bizinc protease of biomedical significance. According to this specificity, a series of phosphonic and phosphinic compounds have been put forward as novel putative inhibitors of the enzyme. These phosphonic and phosphinic compounds were derivatives of methionine and norleucine as both single amino acids and dipeptides. The designed inhibitors were synthesised and tested towards the peptidase isolated from porcine kidneys using an improved separation procedure affording superior homogeneity. Unexpectedly, organophosphorus derivatives of methionine and norleucine exhibited moderat…

Common variants at VRK2 and TCF4 conferring risk of schizophrenia

2011

To access publisher full text version of this article. Please click on the hyperlink in Additional Links field. Common sequence variants have recently joined rare structural polymorphisms as genetic factors with strong evidence for association with schizophrenia. Here we extend our previous genome-wide association study and meta-analysis (totalling 7 946 cases and 19 036 controls) by examining an expanded set of variants using an enlarged follow-up sample (up to 10 260 cases and 23 500 controls). In addition to previously reported alleles in the major histocompatibility complex region, near neurogranin (NRGN) and in an intron of transcription factor 4 (TCF4), we find two novel variants show…
