- Synaptogenesis, the formation of functional synapses, is a crucial step for the development of the central nervous system. Among the genes involved in this process are cell adhesion molecules, such as protocadherins and neuroligins, which are essential factors for the identification of the appropriate partner cell and the formation of synapses. In this work, we studied the expression and the genetic variability of two closely related members of the protocadherin family PCDH11X/Y, located on the X and the Y chromosome, respectively. PCDH11Y is one of the rare genes specific to the hominoid lineage, being absent in other primates. Expression analysis indicated that transcripts of the PCDH11X/Y genes are mainly detected in the cortex of the human brain. Mutation screening of 30 individuals with autism identified two PCDH11Y polymorphic amino acid changes, F885V and K980N. These variations are in complete association, appeared during human evolution approximately 40,000 years ago and represent informative polymorphisms to study Y chromosome variability in populations. We studied the frequency of these variants in males with autism spectrum disorders (n = 110), attention deficit hyperactivity disorder (ADHD; n = 61), bipolar disorder (n = 61), obsessive-compulsive disorder (n = 51), or schizophrenia (n = 61) and observed no significant differences when compared to ethnically-matched control populations. These findings do not support the role of PCDH11Y, or more generally of a frequent specific Y chromosome, in the susceptibility to these neuropsychiatric disorders.

- Here we demonstrate that by using non-toxic fractions of saponin combined with CTA1-DD we can achieve a safe and above all highly efficacious mucosal adjuvant vector. We optimized the construction, tested the requirements for function and evaluated proof-of-concept in an influenza A virus challenge model. We demonstrated that the CTA1-3M2e-DD/ISCOMS vector provided 100% protection against mortality and greatly reduced morbidity in the mouse model. The immunogenicity of the vector was superior to other vaccine formulations using the ISCOM or CTA1-DD adjuvants alone. The versatility of the vector was best exemplified by the many options to insert, incorporate or admix vaccine antigens with the vector. Furthermore, the CTA1-3M2e-DD/ISCOMS could be kept 1 year at 4°C or as a freeze-dried powder without affecting immunogenicity or adjuvanticity of the vector. Strong serum IgG and mucosal IgA responses were elicited and CD4 T cell responses were greatly enhanced after intranasal administration of the combined vector. Together these findings hold promise for the combined vector as a mucosal vaccine against influenza virus infections including pandemic influenza. The CTA1-DD/ISCOMS technology represents a breakthrough in mucosal vaccine vector design which successfully combines immunomodulation and targeting in a safe and stable particulate formation.

- PURPOSE: The aim of this study was to evaluate a phenotypic cell panel with tumor cells from various patients and normal cells for preclinical profiles of antitumor efficacy and toxicity of anticancer drugs.METHODS: The antitumor activity of fourteen anticancer drugs was tested in over one hundred tumor samples from patients with solid or hematological malignancies. Drug activity against four normal cell types was used for the assessment of normal tissue toxicity. In vitro activity of the drugs was compared with indications approved by the Food and Drug Administration and established adverse event profiles.RESULTS: In general, in vitro drug activity in tumor cells from patients reflected known clinical activity of the drugs investigated. For example, the clinical activity of imatinib in chronic myeloid leukemia was clearly detected in the tumor panel. Further, and in accordance with clinical use, cisplatin and bortezomib showed high activity in ovarian cancer and myeloma samples, respectively. The normal cell models roughly reflected known clinical toxicity profiles and were able to detect differences in therapeutic index, e.g., between targeted drugs and classical cytotoxic agents. For example, the high tolerability of imatinib and the well-known renal toxicity of cisplatin were demonstrated.CONCLUSIONS: In preclinical drug development, primary tumor cells from patients can be used for the prediction of cancer diagnosis-specific activity and may aid in the selection of diagnoses for clinical trials. By using tumor and toxicity panels together, information about therapeutic index may be derived, which may be useful when choosing among drug candidates with similar tumor effects.

- Piperlongumine, a natural product from the plant Piper longum, has demonstrated selective cytotoxicity to tumor cells and to show anti-tumor activity in animal models [1]. Cytotoxicity of piperlongumine has been attributed to increase in reactive oxygen species (ROS) in cancer cells. We here report that piperlongumine is an inhibitor of the ubiquitin-proteasome system (UPS). Exposure of tumor cells to piperlongumine resulted in accumulation of a reporter substrate known to be rapidly degraded by the proteasome, and of accumulation of ubiquitin conjugated proteins. However, no inhibition of 20S proteolytic activity or 19S deubiquitinating activity was observed at concentrations inducing cytotoxicity. Consistent with previous reports, piperlongumine induced strong ROS activation which correlated closely with UPS inhibition and cytotoxicity. Proteasomal blocking could not be mimicked by agents that induce oxidative stress. Our results suggest that the anti-cancer activity of piperlongumine involves inhibition of the UPS at a pre-proteasomal step, prior to deubiquitination of malfolded protein substrates at the proteasome, and that the previously reported induction of ROS is a consequence of this inhibition.

- Cellular cardiomyoplasty is an attractive option for the treatment of severe heart failure. It is, however, still unclear and controversial which is the most promising cell source. Therefore, we investigated and examined the fate and functional impact of bone marrow (BM) cells and embryonic stem cell (ES cell)-derived cardiomyocytes after transplantation into the infarcted mouse heart. This proved particularly challenging for the ES cells, as their enrichment into cardiomyocytes and their long-term engraftment and tumorigenicity are still poorly understood. We generated transgenic ES cells expressing puromycin resistance and enhanced green fluorescent protein cassettes under control of a cardiac-specific promoter. Puromycin selection resulted in a highly purified (>99%) cardiomyocyte population, and the yield of cardiomyocytes increased 6-10-fold because of induction of proliferation on purification. Long-term engraftment (4-5 months) was observed when co-transplanting selected ES cell-derived cardiomyocytes and fibroblasts into the injured heart of syngeneic mice, and no teratoma formation was found (n = 60). Although transplantation of ES cell-derived cardiomyocytes improved heart function, BM cells had no positive effects. Furthermore, no contribution of BM cells to cardiac, endothelial, or smooth muscle neogenesis was detected. Hence, our results demonstrate that ES-based cell therapy is a promising approach for the treatment of impaired myocardial function and provides better results than BM-derived cells.

- Good outcomes when emergency physicians diagnosed deep vein thrombosis Deep vein thrombosis of the lower limb is best diagnosed with ultrasound. Internationally, several studies have shown promising and often equal results when emergency physicians have been compared with radiologists in diagnosing thrombosis. Our results confirm these findings in a non-academic hospital and for the first time in a Swedish setting. Our findings form the basis for a multi-centre study on new diagnostic routines in patients with suspected proximal deep vein thrombosis in the emergency department, potentially resulting in faster and more resource-effective management.
