Microarray analysis of Arabidopsis ara6-1 mutant

ABSTRACT: Endosomal trafficking plays an integral role in various eukaryotic cell activities. In animal cells, a member of the RAB GTPase family, RAB5, is known as a key regulator of various endosomal functions, which include endosomal fusion, endosomal signaling, and endosomal motility. In addition to orthologs of animal RAB5, plants harbor the plant-unique RAB5 group, ARA6 group, which is conserved in all land plant lineages. The Arabidopsis genome encodes three RAB5 members: two conventional type RAB5 (ARA7 and RHA1) and one plant-specific ARA6. It has been already reported that ARA6 mediates a trafficking pathway from endosomes to the plasma membrane, and also shown to be involved in salt stress tolerance and flowering. However, physiological functions of ARA6 and their detailed mechanism are still remained elusive. In this study, we carried out a microarray analysis of the ara6-1 mutant. Possible involvement of ARA6 in sugar metabolism will be reported. The transcriptional profiling between the wild-type Col. and a RAB5 knock out mutant, ara6-1.

The Plant-Specific RAB5 GTPase ARA6 is Required for Starch and Sugar Homeostasis in Arabidopsis thaliana

Project description:Endosomal trafficking plays integral roles in various eukaryotic cell activities. In animal cells, a member of the RAB GTPase family, RAB5, is a key regulator of various endosomal functions. In addition to orthologs of animal RAB5, plants harbor the plant-specific RAB5 group, the ARA6 group, which is conserved in land plant lineages. In Arabidopsis thaliana, ARA6 and conventional RAB5 act in distinct endosomal trafficking pathways; ARA6 mediates trafficking from endosomes to the plasma membrane, whereas conventional RAB5 acts in endocytic and vacuolar trafficking pathways. ARA6 is also required for normal salt and osmotic stress tolerance, although the functional link between ARA6 and stress tolerance remains unclear. In this study, we investigated ARA6 function in stress tolerance by monitoring broad-scale changes in gene expression in the ara6 mutant. A comparison of the expression profiles between wild-type and ara6‐1 plants revealed that the expression of the Qua-Quine Starch (QQS) gene was significantly affected by the ara6‐1 mutation. QQS is involved in starch homeostasis, consistent with the starch content decreasing in the ara6 mutants to approximately 60% of that of the wild-type plant. In contrast, the free and total glucose content increased in the ara6 mutants. Moreover, the proliferation of Pseudomonas syringae pv. tomato DC3000 was repressed in ara6 mutants, which could be attributed to the elevated sugar content. These results suggest that ARA6 is responsible for starch and sugar homeostasis, most probably through the function of QQS.

The PripA-TbcrA complex-centered Rab GAP cascade facilitates macropinosome maturation in Dictyostelium

Project description:Macropinocytosis, an evolutionarily conserved mechanism mediating nonspecific bulk uptake of extracellular fluid, has been ascribed diverse functions. How nascent macropinosomes mature after internalization remains largely unknown. By searching for proteins that localize on macropinosomes during the Rab5-to-Rab7 transition stage in Dictyostelium, we uncover a complex composed of two proteins, which we name PripA and TbcrA. We show that the Rab5-to-Rab7 conversion involves fusion of Rab5-marked early macropinosomes with Rab7-marked late macropinosomes. PripA links the two membrane compartments by interacting with PI(3,4)P2 and Rab7. In addition, PripA recruits TbcrA, which acts as a GAP, to turn off Rab5. Thus, the conversion to Rab7 is linked to inactivation of the upstream Rab5. Consistently, disruption of either pripA or tbcrA impairs Rab5 inactivation and macropinocytic cargo processing. Therefore, the PripA-TbcrA complex is the central component of a Rab GAP cascade that facilitates programmed Rab switch and efficient cargo trafficking during macropinosome maturation.

Stapled peptide inhibitors of RAB25 target context-specific phenotypes in cancer

Project description:The Ras-family small GTPase RAB25 is involved in numerous aspects of endosomal protein trafficking and cell polarity. Recent evidence has established a role for RAB25, as well as related RAB-family and effector proteins, in oncogenic signaling, highlighting the need for chemical probes targeting this class of proteins. Here we report the development of all-hydrocarbon stabilized peptides targeting RAB25 derived from the RAB-binding FIP-family of proteins. Relative to unmodified FIP peptides, optimized stapled peptides show markedly increased structural stability, binding affinity, cell permeability and inhibition of RAB25:FIP complex formation. RAB25 expression has been shown to promote both pro- and anti-oncogenic phenotypes in specific cellular contexts. Stapled peptide RFP14 treatment of breast and ovarian cancer cell lines, in which RAB25 is pro-oncogenic, inhibited migration and proliferation in a RAB25-dependent manner. In contrast, treatment of a triple-negative breast cancer cell line in which RAB25 is tumor suppressive augmented proliferation and migration. Gene expression (RNA Seq) profiling identified significantly altered transcripts in response to RAB25 expression in ovarian cancer cells, and treatment with the optimized stapled peptide RFP14 reversed this expression profile. These data validate first-in-class chemical probes targeting RAB-family proteins and support the role of RAB25 in regulating context-specific oncogenic phenotypes.

Comparative proteomic identification of Rab GTPase interactors in Arabidopsis

Project description:Rab GTPases are key spatio-temporal regulators of endomembrane trafficking and endomembrane compartment identity across eukaryotes. This therefore makes them ideal targets for study of endomembrane compartment and trafficking pathway composition. In plants, few definitive interactors of Rab GTPases and cargoes of their associated trafficking pathways are known, hindering our understanding of how plants may accomplish and support some unique aspects and requirements of their post-Golgi trafficking systems. The purpose of this work was to identify candidate interactors of different post-Golgi Rab GTPases in Arabidopsis. Co-IPs were performed against tagged-versions of three different post-Golgi Rab GTPases: RAB-A5c, RAB-A2a and RAB-G3f, as well as against control wild-type (Col-0) plants. Comparative ranking of the different proteomes produced candidate interactor lists enriched in possible specific interactors of each Rab GTPase, as well as generic shared interactors. This dataset forms the basis of the characterisation work of several upcoming publications.

Expression data in single and double knockouts of AtNHX5 and AtNHX6 in Arabidopsis

Project description:We generated single and double knockouts of AtNHX5 and AtNHX6 in order to invesigate possible functions in Arabidopsis. nhx5/nhx6 exhibited severe growth retardation related to cell size and proliferation, as well as endosomal trafficking perutrbations. The results implicate endosomal NHX antiporters in novel cellular functions. In order to investigate further the possible functions of AtNHX5 and AtNHX6, we compared the transcrptional profiles of single and double AtNHX5 and AtNHX6 knockouts. We looked for changes in gene expression might help us to elucidate the molecular events associated with the apparent requirement of AtNHX5 and AtNHX6 for normal growth and development. Rosette leaves from 4 weeks old plants grown on soil under normal conditons and 8h L / 16 D were collected for RNA extraction and hybridization on Affymetrix microarray chips.

Comparison of expression data between control and Ovo1 morphant zebrafish embryos

Project description:A fundamental issue in cell biology is how migratory cell behaviors are controlled by dynamically regulated cell adhesion. Vertebrate neural crest (NC) cells rapidly alter cadherin expression and localization at the cell surface during migration. Secreted Wnts induce some of these changes in NC adhesion and also promote specification of NC-derived pigment cells. Here, we show that the zebrafish transcription factor Ovo1 is a Wnt target gene that controls migration of pigment precursors by regulating the intracellular movements of N-cadherin (Ncad). Ovo1 genetically interacts with Ncad and its depletion causes Ncad to accumulate inside cells. Ovo1-deficient embryos strongly upregulate factors involved in intracellular trafficking, including several rab GTPases, known to modulate cellular localization of cadherins. Surprisingly, NC cells express high levels of many of these rab genes in the early embryo, chemical inhibitors of Rab functions rescue NC development in Ovo1-deficient embryos and overexpression of a Rab-interacting protein leads to similar defects in NC migration. These results suggest that Ovo proteins link Wnt signaling to intracellular trafficking pathways that localize Ncad in NC cells and allow them to migrate. Similar processes probably occur in other cell types in which Wnt signaling promotes migration.

Phagolysosomal proteomics identifies DHN-melanin-regulated processes in activated macrophage in response to Aspergillus fumigatus conidia

Project description:Infection by the human pathogenic fungus Aspergillus fumigatus is initialized by the outgrowth of asexual spores (conidia) into the lung tissue of the immunocompromised host following an inhalation of the airborne conidia. The resident phagocytes, the alveolar macrophages are the first immune cells to encounter invading conidia. However, A. fumigatus conidia employ versatile mechanisms to evade the host immune defense and establish a severe invasive infection. Previously, we showed that depending on the presence of conidial 1,8-dihydroxynaphthalene (DHN) melanin, A. fumigatus circumvents intracellular killing by manipulating the phagolysosomal maturation process. Here, by comparative dual proteomics we analyzed proteins of phagolysosomes containing melanized wild-type or non-melanized pksP mutant conidia. Bioinformatics compiled a regulatory module of differentially abundant proteins that mirrors processes targeted by the fungus for immune evasion. Those are i.e. vATPAse-driven phagolysosomal acidification, endocytic trafficking, signal transduction, energy metabolism and immune response. In detail, we found alterations of vATPase complex assembly and impaired abundances of mTOR and MAPK signaling molecules, Rab5 and Vamp8 mediators of endosomal trafficking as well as Lamp1 and cathepsin Z lysosomal markers.
