Recent evidence indicates that Parkinson's disease and diabetes, both age-related chronic diseases, share remarkably similar dysregulated pathways. Exposure to environmental factors and genetic susceptibility play a role in the etiology and progression of both diseases. In light of recent findings, an intriguing hypothesis has emerged that suggests that mitochondrial dysfunction, endoplasmic reticulum stress, inflammation, and alterations in metabolism may lead to insulin resistance and, ultimately, to diabetes and/or neurodegeneration. In this article, we summarize the studies that have addressed the relationship between Parkinson's disease and diabetes and propose that disruptions in these shared molecular networks lead to both chronic diseases. © 2013 Elsevier Ltd.

Macrophage polarization contributes to distinct human pathologies. In tumors, a polarized M2 phenotype called tumor-associated macrophages (TAMs) are associated with promotion of invasion and angiogenesis. In cancer cells, vacuolar ATPase (V-ATPase), a multi-subunit enzyme, is expressed on the plasma/vesicular membranes and critically influences the metastatic behavior. In addition, the soluble, cleaved N-terminal domain of a2 isoform of V-ATPase (a2NTD) is associated with in vitro induction of pro-tumorigenic properties in monocytes. This activity of a2 isoform of V-ATPase (a2V) caused us to investigate its role in cancer progression through the evaluation of the immunomodulatory properties of a2NTD. Here, we present direct evidence that surface expression of V-ATPase is associated with macrophage polarization in tumor tissue. Macrophages from BALB/c mice (peritoneal/bone marrow derived) were stimulated with recombinant a2NTD in both ex vivo and in vivo systems and evaluated for TAM characteristics. a2V was highly expressed in tumor tissues (breast and skin) as well as on the surface of tumor cell lines. The a2NTD-stimulated macrophages (a2MΦ) acquired TAM phenotype, which was characterized by elevated expression of mannose receptor-1, Arginase-1, interleukin-10 and transforming growth factor-β. a2MΦ also exhibited increased production of other tumorigenic factors including matrix metalloproteinase-9 and vascular endothelial growth factor. Further, a2MΦ were cocultured with mouse B-16F0 melanoma cells for their functional characterization. The coculture of these a2MΦ subsequently increased the invasion and angiogenesis of less invasive B-16F0 cells. When cocultured with naive T cells, a2MΦ significantly inhibited T-cell activation. The present data establish the role of V-ATPase in modulating a macrophage phenotype towards TAMs through the action of a2NTD, suggesting it to be a potential therapeutic target in cancer.

It has become increasingly apparent that gene expression is regulated by the functional interplay between spatial genome organization and nuclear architecture. Within the nuclear environment a variety of distinct nuclear bodies exist. They are dynamic, self-organizing structures that do not assemble as pre-formed entities but rather emerge as a direct reflection of specific activities associated with gene expression and genome maintenance. Here I summarize recent findings on functions of some of the most prominent nuclear bodies, including the nucleolus, Cajal body, PML nuclear body, Polycomb group body and the 53BP1 nuclear body. The emerging view is that their organization is orchestrated by similar principles, and they function in fundamental cellular processes involved in homeostasis, differentiation, development and disease. © 2012 Elsevier Ltd.

ABSTRACT: Study Design. Retrospective multivariate analysis of a prospectively collected, multi-center database.Objective. To identify patient characteristics and perioperative risk factors associated with postoperative infectious complications following single level lumbar fusion (SLLF) surgery.Summary of Background Data. Postoperative infection is a known complication following lumbar fusion. Risk factors for infectious complications following lumbar fusion have not been investigated using select set of SLLF procedures.Methods. Patients who underwent SLLF between 2006 and 2011 were identified from the American College of Surgeons National Surgical Quality Improvement Program database. Multivariate logistic regression analyses were performed to identify pre- and intra-operative risk factors associated with postoperative infection.Results. 3,353 patients were analyzed in this study. Overall, 173 (5.2%) patients experienced a postoperative infection, including 86 (2.6%) surgical site infections (SSI) and 111 (3.3%) non-SSI infectious complications (pneumonia, UTI, sepsis/septic shock). Twenty four (0.7%) patients experienced both SSI and non-SSI infectious complications. Postoperative SSI were associated with obesity (OR 1.628, 95% CI 1.042-2.544), American Society of Anesthesiologist (ASA) class>2 (OR 2.078, 95% CI 1.309-3.299), and operative time >6 hrs (OR 2.573, 95% CI 1.310-5.056). Risk factors for non-SSI infectious complications included age (60-69 yrs, OR 3.279, 95% CI 1.541-6.980;≥70 yrs, OR 3.348, 95% CI 1.519-7.378), female gender (OR 1.791, 95% CI 1.183-2.711), creatinine>1.5mg/dL (OR 2.400, 95% CI 1.138-5.062), ASA >2 (OR 1.835, 95% CI 1.177-2.860), and operative time >6hrs (OR 3.563, 95% CI 2.082-6.097).Conclusions. Across a wide study population, we identified that obesity, advanced ASA classification, and longer operative time were predictive of postoperative SSI. We also demonstrated that increased age, female gender, serum creatinine>1.5mg/dL, and prolonged operative duration are associated with non-SSI infectious complications after SLLF. Continued efforts to elucidate and optimize perioperative risk factors are warranted to improve outcomes in patients requiring spinal fusion. © 2014 by Lippincott Williams & Wilkins

The biogenesis of the many functional compartments contained in the mammalian cell nucleus is poorly understood. More specifically, little is known regarding the initial nucleation step required for nuclear body formation. Here we show that RNA can function as a structural element and a nucleator of nuclear bodies. We find that several types of coding and noncoding RNAs are sufficient to de novo assemble, and are physiologically enriched in, histone locus bodies (with associated Cajal bodies), nuclear speckles, paraspeckles and nuclear stress bodies. Formation of nuclear bodies occurs through recruitment and accumulation of proteins resident in the nuclear bodies by nucleating RNA. These results demonstrate that transcription is a driving force in nuclear body formation and RNA transcripts can function as a scaffold in the formation of major nuclear bodies. Together, these data suggest that RNA-primed biogenesis of nuclear bodies is a general principle of nuclear organization. © 2011 Macmillan Publishers Limited. All rights reserved.

Increasing evidence indicates that Parkinsons disease (PD) and type 2 diabetes (T2DM) share dysregulated molecular networks. 84 genes shared between PD and T2DM were identified from curated disease-gene databases. Nitric oxide biosynthesis, lipid and carbohydrate metabolism, insulin secretion and inflammation were identified as common dysregulated pathways. A network prioritization approach was implemented to rank genes according to their distance to seed genes and their involvement in common biological pathways. This disclosure reinforces the idea that shared molecular networks between PD and T2DM provide an additional source of biologically meaningful biomarkers.

Network-based meta-analysis of four independent microarray studies identified the hepatocyte nuclear factor (HNF4A), a transcription factor associated with gluconeogenesis and diabetes, as a central regulatory hub gene upregulated in blood of PD patients. In parallel, the polypyrimidine tract binding protein 1 (PTBP1), involved in the stabilization and mRNA translation of insulin, was identified as the most downregulated gene. Using both markers, PD patients were classified with 90% sensitivity and 80% specificity. Longitudinal performance analysis demonstrated that relative abundance of HNF4A and PTBP1 mRNAs significantly decreased and increased, respectively, in PD patients during 3 years follow up period. The inverse regulation of HNF4A and PTBP1 provides a molecular rationale for the altered insulin signaling observed in PD patients. The longitudinally dynamic biomarkers identified in this study may be useful for monitoring disease-modifying therapies for PD.
