Kaposi's sarcoma-associated herpesvirus (KSHV), etiologically associated with Kaposi's sarcoma, uses integrins (α3β1, αVβ3, and αVβ5) and associated signaling to enter human dermal microvascular endothelial cells (HMVEC-d), an in vivo target of infection. KSHV infection activated c-Cbl, which induced the selective translocation of KSHV into lipid rafts (LRs) along with the α3β1, αVβ3, and xCT receptors, but not αVβ5. LR-translocated receptors were monoubiquitinated, leading to productive macropinocytic entry, whereas non-LR-associated αVβ5 was polyubiquitinated, leading to clathrin-mediated entry that was targeted to lysosomes. Because the molecule(s) that integrate signal pathways and productive KSHV macropinocytosis were unknown, we immunoprecipitated KSHV-infected LR fractions with anti-α3β1 antibodies and analyzed them by mass spectrometry. The tyrosine kinase EphrinA2 (EphA2), implicated in many cancers, was identified in this analysis. EphA2 was activated by KSHV. EphA2 was also associated with KSHV and integrins (α3β1 and αVβ3) in LRs early during infection. Preincubation of virus with soluble EphA2, knockdown of EphA2 by shRNAs, or pretreatment of cells with anti-EphA2 monoclonal antibodies or tyrosine kinase inhibitor dasatinib significantly reduced KSHV entry and gene expression. EphA2 associates with c-Cbl-myosin IIA and augmented KSHV-induced Src and PI3-K signals in LRs, leading to bleb formation and macropinocytosis of KSHV. EphA2 shRNA ablated macropinocytosis-associated signaling events, virus internalization, and productive nuclear trafficking of KSHV DNA. Taken together, these studies demonstrate that the EphA2 receptor acts as a master assembly regulator of KSHV-induced signal molecules and KSHV entry in endothelial cells and suggest that the EphA2 receptor is an attractive target for controlling KSHV infection.

Although it is challenging for individuals with cocaine addiction to achieve abstinence, the greatest difficulty is avoiding relapse to drug taking, which is often triggered by cues associated with prior cocaine use. This vulnerability to relapse persists for long periods (months to years) after abstinence is achieved. Here, I discuss rodent studies of cue-induced cocaine craving during abstinence, with a focus on neuronal plasticity in the reward circuitry that maintains high levels of craving. Such work has the potential to identify new therapeutic targets and to further our understanding of experience-dependent plasticity in the adult brain under normal circumstances and in the context of addiction. © 2016 Macmillan Publishers Limited.

Activation of medium spiny neurons (MSNs) of the nucleus accumbens is critical for goal-directed behaviors including cocaine seeking. Studies in cocaine-experienced rodents have revealed three major categories of neuroadaptations that influence the ability of glutamate inputs to activate MSNs: changes in synaptic AMPA receptor levels, changes in extracellular non-synaptic glutamate levels and changes in MSN intrinsic membrane excitability. Most studies have focused on one of these adaptations. This review will consider the possibility that they are causally related and speculate about how time-dependent changes in their interactions may regulate MSN output during early and late withdrawal from repeated cocaine exposure. © 2010 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.

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.
