Résumé :

ABSTRACT Rhizobium meliloti mutants defective in thephoCDET-encoded phosphate transport system form root nodules on alfalfa plants that fail to fix nitrogen (Fix−). We have previously reported that two classes of second-site mutations can suppress the Fix− phenotype ofphoCDET mutants to Fix+. Here we show that one of these suppressor loci (sfx1) contains two genes, orfA and pit, which appear to form an operon transcribed in the order orfA-pit. The Pit protein is homologous to various phosphate transporters, and we present evidence that three suppressor mutations arose from a single thymidine d

Résumé :

The cell-to-cell movement of Turnip crinkle virus (TCV) in Nicotiana benthamiana requires the presence of its coat protein (CP), a known suppressor of RNA silencing. RNA transcripts of a TCV construct containing a reporter gene (green fluorescent protein) (TCV-sGFP) in place of the CP open reading frame generated foci of three to five cells. TCV CP delivered in trans by Agrobacterium tumefaciens infiltration potentiated movement of TCV-sGFP and increased foci diameter, on average, by a factor of four. Deletion of the TCV movement proteins in TCV-sGFP (construct TCVΔ92-sGFP) abolished the movem

Abstract Abstract 181 Introduction: The ubiquitous mold Aspergillus fumigatus (A. fumigatus) induces two forms of pathogenesis: invasive aspergillosis in neutropenic patients and allergic aspergillosis in patients with chronic obstructive lung disease as well as in immunosuppressed patients. Mouse models of aspergillosis suggest that not only effector T cells (Teff) but also regulatory T cells (Treg) play a crucial role for the regulation of a protective T cell-mediated immunity to A. fumigatus. However, it is little-known about the involvement of Treg during A. fumigatus infection in humans.

Résumé :

We characterized two yeast loci, MDS3 and PMD1, that negatively regulate sporulation. Initiation of sporulation is mediated by the meiotic activator IME1, which relies on MCK1 for maximal expression. We isolated the MDS3-1 allele (encoding a truncated form of Mds3p) as a suppressor that restores IME1 expression in mck1 mutants. mds3 null mutations confer similar suppression phenotypes as MDS3-1, indicating that Mds3p is a negative regulator of sporulation and the MDS3-1 allele confers a dominant-negative phenotype. PMD1 is predicted to encode a protein sharing significant similarity with Mds3p

Abstract The induction of CD11b+Gr-1+ myeloid-derived suppressor cells (MDSCs) is an important immune-evading mechanism used by tumors. However, the exact nature and function of MDSCs remain elusive, especially because they constitute a heterogeneous population that has not yet been clearly defined. Here, we identified 2 distinct MDSC subfractions with clear morphologic, molecular, and functional differences. These fractions consisted of either mononuclear cells (MO-MDSCs), resembling inflammatory monocytes, or low-density polymorphonuclear cells (PMN-MDSCs), akin to immature neutrophils. Inte

Résumé :

Myeloid-derived suppressor cells are heterogenic immature myeloid cells, which possess suppressor activity and play an important role in both, tumor progression and metastasis. The accumulation of MDSCs is induced primarily by factors that are secreted by the tumor microenvironment, which disturb myelopoiesis that occurs in the bone marrow and enables the migration of immature myeloid cells into the tumor. MDSCs promote tumor growth by inhibiting the activity of immunocompetent cells, as well as by activating non-immunological processes, such as tumor angiogenesis, the degradation of extracell

Metastatic colorectal cancer (mCRC) is characterized by the expression of cellular oncogenes, the loss of tumor suppressor gene function. Therefore, identifying integrated signaling between onco-suppressor genes may facilitate the development of effective therapy for mCRC. To investigate these pathways we utilized cell lines and patient derived organoid models for analysis of gene/protein expression, gene silencing, overexpression, and immunohistochemical analyses. An inverse relationship in expression of oncogenic FoxM1 and tumor suppressor RASSF1A was observed in various stages of CRC. This

In contrast to most dot/icm genes, which are dispensable for growth on bacteriological media, dotL is required for the viability of wild-type L. pneumophila.

Abstract Abstract 2474 Aberrant expression of Hox genes and their cofactors Pbx and Meis1 has been detected in approximately 50% of all human leukemias, and proteins interacting with these homeodomain factors could play a major role in leukemia development. Studies in drosophila showed that hth/MEIS directly interacts with YKI, a component of the Hippo signaling pathway (Peng HW et al., 2009). The core components of this pathway in the mammalian cells are the kinases MST 1 or 2 and LATS 1 or 2, and the downstream transcription cofactors WWTR1 and YAP (homologues of the drosophila Yki).

Abstract We previously reported a candidate myeloid tumor-suppressor gene Miki (mitotic kinetic regulator, LOC253012) isolated from a common microdeletion cluster in chromosome subband 7q21.2 that was identified by microarray-based CGH analyses of JMML (ASH Annual Meeting, 2006 and 2007). Deletion of one Miki gene was also detected in 28 % of adult MDS/AML patients by copy-number assessment using real-time quantitative PCR (qPCR). Miki encodes a centrosomal protein: downregulation of Miki by siRNA disturbs the maturation and positioning of centrosomes, as well as spindle formation in mitotic c

It has been known for years that rodents harbor a unique population of CD4+CD25+ “professional” regulatory/suppressor T cells that is crucial for the prevention of spontaneous autoimmune diseases. Here we demonstrate that CD4+CD25+CD45RO+ T cells (mean 6% of CD4+ T cells) are present in the blood of adult healthy volunteers. In contrast to previous reports, these CD4+CD25+ T cells do not constitute conventional memory cells but rather regulatory cells exhibiting properties identical to their rodent counterparts.

Though Abl inhibitors are often successful therapies for the initial stages of chronic myelogenous leukemia (CML), refractory cases highlight the need for novel molecular insights. We demonstrate that mice deficient in the enzyme 12/15-lipoxygenase (12/15-LO) develop a myeloproliferative disorder (MPD) that progresses to transplantable leukemia. Although not associated with dysregulation of Abl, cells isolated from chronic stage 12/15-LO–deficient (Alox15) mice exhibit increased activation of the phosphatidylinositol 3–kinase (PI3-K) pathway, as indicated by enhanced phosphorylation of Akt.

11105 Background: Mutation, deletion, or epigenetic silencing of tumor suppressor genes is a near universal feature of malignant cells. However, therapeutic strategies for restoring the function of mutated or deleted genes have proven difficult. Synthetic lethality, an event in which the simultaneous perturbation of two genes results in cellular death, has been proposed as a method to selectively target cancer cells. Identifying and pharmacologically inhibiting proteins encoded by genes that are synthetic lethal with known tumor suppressor mutations should result in selective toxicity to tumor

RAT7/NUP159 was identified previously in a screen for genes whose products are important for nucleocytoplasmic export of poly(A)+ RNA and encodes an essential nucleoporin. We report here the identification of RSS1 (Rat Seven Suppressor) as a high-copy extragenic suppressor of the rat7-1 temperature-sensitive allele. Rss1p encodes a novel essential protein of 538 amino acids, which contains an extended predicted coiled-coil domain and is located both at nuclear pore complexes (NPCs) and in the cytoplasm.

Résumé :

Abstract CpG islands in the 5′ regulatory regions of genes are generally protected from cytosine methylation as methylation in a promoter can result in transcriptional silencing of the associated gene. Failure of a cell to prevent methylation in the promoter regions of tumor suppressor genes contributes to the onset and progression of cancers. The demethylating agent 5-aza-2′deoxycytidine (DAC) and the histone deacetylase inhibitor suberoyl anilide bishydroxamide (SAHA) possess potent antitumorigenic properties against myeloid disorders.

The analysis of the molecular mechanisms governing multistep carcinogenesis became experimentally approachable since the identification and characterization in tumor cells of altered or activated versions of cellular genes (oncogenes) that normally control cell growth and differentiation. The activating mutations confer new properties to the oncogene products and should therefore be considered as gain of function mutations. In addition, the oncogenes appear to act as dominant genetic traits since they act also in the presence of the homologous wild-type allele. However, the concept of a domina

Abstract Systemic mastocytosis (SM) is a myeloid neoplasm involving mast cells (MCs) and their progenitors. In most cases, neoplastic cells display the D816V-mutated variant of KIT. KIT D816V exhibits constitutive tyrosine kinase (TK) activity and has been implicated in increased survival and growth of neoplastic MCs. Recent data suggest that the proapoptotic BH3-only death regulator Bim plays a role as a tumor suppressor in various myeloid neoplasms. We found that KIT D816V suppresses expression of Bim in Ba/F3 cells. The KIT D816–induced down-regulation of Bim was rescued by the KIT-targetin
