The importance of these molecules is exemplified by the variety of physiological roles they play. Perhaps, the most extensively studied member of this family is the TRPV1 ion channel; nonetheless, the activity of TRPV4 has been associated to several physio and pathophysiological processes, and its dysfunction can lead to severe consequences. Several lines of evidence derived from animal models and even clinical trials in humans highlight TRPV4 as a therapeutic target and as a protein that will receive even more attention in the near future, as will be reviewed here. -
Mapping of SUMO Sites and Analysis of Sumoylation Changes Induced by External Stimuli

Identification of modified proteins is a critical step to get further insight into the small ubiquitin-related modifier (SUMO)-conjugatedresiduesinpro- function of SUMOylation. Indeed, the identification of SUMO teins is critical for understanding the role of SUMOylation but remains sites allows the generation of non-SUMOylatable mutants and the experimentally challenging.

Drosophila Tau Negatively Regulates Translation and Olfactory Long-Term Memory, but Facilitates Footshock Habituation and Cytoskeletal Homeostasis

Skoulakis1 1Institute for Fundamental Biomedical Research, and 2Institute for Bioinnovation, Biomedical Sciences Research Centre “Alexander Fleming,” 16672 Vari, Greece Although the involvement of pathological tau in neurodegenerative dementias is indisputable, its physiological roles have remained elusive in part because its abrogation has been reported without overt phenotypes in mice and Drosophila. This was addressed using the recently described Drosophila tauKO and Mi{MIC} mutants and focused on molecular and behavioral analyses. Initially, we show that Drosophila tau (dTau) loss precipitates dynamic cytoskeletal changes in the adult Drosophila CNS and translation upregulation. Signif- icantly, we demonstrate for the first time distinct roles for dTau in adult mushroom body (MB)-dependent neuroplasticity as its down- regulation within ␣ЈЈneurons impairs habituation. In accord with its negative regulation of translation, dTau loss specifically enhances protein synthesis-dependent long-term memory (PSD-LTM), but not anesthesia-resistant memory. In contrast, elevation of the protein in the MBs yielded premature habituation and depressed PSD-LTM. Therefore, tau loss in Drosophila dynamically alters brain cytoskel- etal dynamics and profoundly affects neuronal proteostasis and plasticity. Key words: Drosophila; habituation; memory; proteome; tau Significance Statement We demonstrate that despite modest sequence divergence, the Drosophila tau (dTau) is a true vertebrate tau ortholog as it interacts with the neuronal microtubule and actin cytoskeleton. -

A total 100 genes were analyzed by the pathway, gene ontology (GO) enrichment analysis, construction of protein-protein interaction (PPI) network, module analysis, construction of target genes—miRNA interaction network, target and genes-transcription factor (TF) interaction. We discuss key issues pertaining to experimental design, data preprocessing, and gene selection methods. Common types of data representation are illustrated. A total of 100 differentially miRNAs were screened and identified by microarray according to fold change the top genes which were significantly 59 genes with up-regulation and 41 genes down regulation, after Gum Arabic administration for 4 days. The data may unravel the future molecular mechanisms of Gum arabic by applying various bio-informatical approaches, we have revealed top score upregulation genes were 23, and down regulated genes with top score were 38. -
A Grainyhead-Like 2/Ovo-Like 2 Pathway Regulates Renal Epithelial Barrier Function and Lumen Expansion

Here, we report that nephric duct, ureteric bud, and collecting duct epithelia express high levels of grainyhead-like homolog 2 (Grhl2) and that nephric duct lumen expansion is defective in Grhl2-deficient mice. In collecting duct epithelial cells, Grhl2 inactivation impaired epithelial barrier formation and inhibited lumen expansion. Molecular analyses showed that GRHL2 acts as a transcrip- tional activator and strongly associates with histone H3 lysine 4 trimethylation. Integrating genome-wide GRHL2 binding as well as H3 lysine 4 trimethylation chromatin immunoprecipitation sequencing and gene expression data allowed us to derive a high-confidence GRHL2 target set. GRHL2 transactivated a group of genes including Ovol2, encoding the ovo-like 2 zinc finger transcription factor, as well as E-cadherin, claudin 4 (Cldn4), and the small GTPase Rab25. Ovol2 induction alone was sufficient to bypass the requirement of Grhl2 for E-cadherin, Cldn4,andRab25 expression. Re-expression of either Ovol2 or a combination of Cldn4 and Rab25 was sufficient to rescue lumen expansion and barrier formation in Grhl2-deficient collecting duct cells. -
Genomic Signatures of Drift and Selection Driven by Predation and Human Pressure in an Insular Lizard Marta Bassitta 1*, Richard P
www.nature.com/scientificreports OPEN Genomic signatures of drift and selection driven by predation and human pressure in an insular lizard Marta Bassitta 1*, Richard P. Brown 2, Ana Pérez‑Cembranos 3, Valentín Pérez‑Mellado 3, José A. Castro 1, Antònia Picornell 1 & Cori Ramon 1 Genomic divergence was studied in 10 small insular populations of the endangered Balearic Islands lizard (Podarcis lilfordi) using double digest restriction‑site associated DNA sequencing. The objectives were to establish levels of divergence among populations, investigate the impact of population size on genetic variability and to evaluate the role of diferent environmental factors on local adaptation. Analyses of 72,846 SNPs supported a highly diferentiated genetic structure, being the populations with the lowest population size (Porros, Foradada and Esclatasang islets) the most divergent, indicative of greater genetic drift. Outlier tests identifed ~ 2% of loci as candidates for selection. Genomic divergence‑Enviroment Association analyses were performed using redundancy analyses based on SNPs putatively under selection, detecting predation and human pressure as the environmental variables with the greatest explanatory power. Geographical distributions of populations and environmental factors appear to be fundamental drivers of divergence. These results support the combined role of genetic drift and divergent selection in shaping the genetic structure of these endemic island lizard populations. Insular populations are naturally isolated systems that harbour high levels of biodiversity and endemism1. Teir characteristic isolation leads to a reduction in gene fow and generates population divergence and speciation2. High levels of genetic structuring also result from frequent physical events combined with the impact of rapid fxation rates in ofen small populations subject to genetic drif and selection3,4. -

However, the significance of the multiple 18 parallel transport pathways that the receptors constitute is poorly understood because only limited 19 numbers of cargo proteins have been reported. Here, we identified cargo proteins specific to the 12 20 species of human import receptors with a high-throughput method that employs stable isotope 21 labeling with amino acids in cell culture, an in vitro reconstituted transport system, and quantitative 22 mass spectrometry. The identified cargoes illuminated the manner of cargo allocation to the 23 receptors. The redundancies of the receptors vary widely depending on the cargo protein. Cargoes 24 of the same receptor are functionally related to one another, and the predominant protein groups in 25 the cargo cohorts differ among the receptors. Thus, the receptors are linked to distinct biological 26 processes by the nature of their cargoes.
