Is Lurasidone more safe and effective in the treatment ofschizoaffective disorder and schizophrenia than other commonanti-psychotic medications?

Objective: The objective of this selective EBM review is to determine whether or not Lurasidone is more safe and effective in the treatment of schizoaffective disorder and schizophrenia than other common anti-psychotic medications. Study Design: Review of two English language randomized double-blinded controlled comparisons and one English language Randomized open-label parallel-group comparison. Data Sources: The randomized double-blinded controlled comparison studies and the randomized open-label parallel-group comparison were all found using PubMed and EBSCOhost databases. All three articles were published in peer-reviewed journals. Outcomes Measured: Participant withdrawal due to adverse effects and treatment failure, patient responses to MATRICS consensus cognitive battery, interview responses, and patient responses on the schizophrenia cognition rating scale were all measured to determine the efficacy and safety of Lurasidone. Results: According to Harvey et. al, the difference between Lurasidone and other common anti-psychotics, such as Ziprasidone, is not statistically significant with a p= 0.058. Potkin, et. al reported that Lurasidone is more safe and effective compared to other common anti-psychotics with a p= 0.020. McEvoy et. al demonstrated the safety and efficacy of lurasidone with p values \u3c0.05. Conclusion: The results from this review are inconclusive. One study with a p value of 0.020 and another with p values \u3c0.05 indicates that Lurasidone is more safe and effective and, but a p value of 0.058 in the third study does not agree with the findings of the other studies

FAK induces expression of Prx1 to promote tenascin-C–dependent fibroblast migration

Fibroblast migration depends, in part, on activation of FAK and cellular interactions with tenascin-C (TN-C). Consistent with the idea that FAK regulates TN-C, migration-defective FAK-null cells expressed reduced levels of TN-C. Furthermore, expression of FAK in FAK-null fibroblasts induced TN-C, whereas inhibition of FAK activity in FAK–wild-type cells had the opposite effect. Paired-related homeobox 1 (Prx1) encodes a homeobox transcription factor that induces TN-C by interacting with a binding site within the TN-C promoter, and it also promotes fibroblast migration. Therefore, we hypothesized that FAK regulates TN-C by controlling the DNA-binding activity of Prx1 and/or by inducing Prx1 expression. Prx1–homeodomain binding site complex formation observed with FAK–wild-type fibroblasts failed to occur in FAK-null fibroblasts, yet expression of Prx1 in these cells induced TN-C promoter activity. Thus, FAK is not essential for Prx1 DNA-binding activity. However, activated FAK was essential for Prx1 expression. Functionally, Prx1 expression in FAK-null fibroblasts restored their ability to migrate toward fibronectin, in a manner that depends on TN-C. These results appear to be relevant in vivo because Prx1 and TN-C expression levels were reduced in FAK-null embryos. This paper suggests a model whereby FAK induces Prx1, and subsequently the formation of a TN-C–enriched ECM that contributes to fibroblast migration

Endothelial cells and pulmonary arterial hypertension: apoptosis, proliferation, interaction and transdifferentiation

Severe pulmonary arterial hypertension, whether idiopathic or secondary, is characterized by structural alterations of microscopically small pulmonary arterioles. The vascular lesions in this group of pulmonary hypertensive diseases show actively proliferating endothelial cells without evidence of apoptosis. In this article, we review pathogenetic concepts of severe pulmonary arterial hypertension and explain the term "complex vascular lesion ", commonly named "plexiform lesion", with endothelial cell dysfunction, i.e., apoptosis, proliferation, interaction with smooth muscle cells and transdifferentiation

Endothelial Jag1-RBPJ signalling promotes inflammatory leucocyte recruitment and atherosclerosis.

AIM: To determine the role of NOTCH during the arterial injury response and the subsequent chronic arterial-wall inflammation underlying atherosclerosis. METHODS AND RESULTS: We have generated a mouse model of endothelial-specific (Cdh5-driven) depletion of the Notch effector recombination signal binding protein for immunoglobulin kappa J region (RBPJ) [(ApoE-/-); homozygous RBPJk conditional mice (RBPJflox/flox); Cadherin 5-CreERT, tamoxifen inducible driver mice (Cdh5-CreERT)]. Endothelial-specific deletion of RBPJ or systemic deletion of Notch1 in athero-susceptible ApoE-/- mice fed a high-cholesterol diet for 6 weeks resulted in reduced atherosclerosis in the aortic arch and sinus. Intravital microscopy revealed decreased leucocyte rolling on the endothelium of ApoE-/-; RBPJflox/flox; Cdh5-CreERT mice, correlating with a lowered content of leucocytes and macrophages in the vascular wall. Transcriptome analysis revealed down-regulation of proinflammatory and endothelial activation pathways in atherosclerotic tissue of RBPJ-mutant mice. During normal Notch activation, Jagged1 signalling up-regulation in endothelial cells promotes nuclear translocation of the Notch1 intracellular domain (N1ICD) and its physical interaction with nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB). This N1ICD-NF-κB interaction is required for reciprocal transactivation of target genes, including vascular cell adhesion molecule-1. CONCLUSIONS: Notch signalling pathway inactivation decreases leucocyte rolling, thereby preventing endothelial dysfunction and vascular inflammation. Attenuation of Notch signalling might provide a treatment strategy for atherosclerosis.This study was funded by grants SAF2013-45543R, RD12/0042/0005 (RIC) and RD12/0019/0003 (TERCEL) from the Spanish Ministry of Economy and Competitiveness (MINECO) to J.L.dlP, RD12/0042/0028 (RIC) to V.A. and RD12/0042/0053 (RIC) and SAF2012-40127 to J.M.G.
