The Caenorhabditis elegans sex determination gene mog-1 encodes a member of the DEAH-Box protein family. (1/700)

In the Caenorhabditis elegans hermaphrodite germ line, the sex-determining gene fem-3 is repressed posttranscriptionally to arrest spermatogenesis and permit oogenesis. This repression requires a cis-acting regulatory element in the fem-3 3' untranslated region; the FBF protein, which binds to this element; and at least six mog genes. In this paper, we report the molecular characterization of mog-1 as well as additional phenotypic characterization of this gene. The mog-1 gene encodes a member of the DEAH-box family. Three mog-1 alleles possess premature stop codons and are likely to be null alleles, and one is a missense mutation and is likely to retain residual activity. mog-1 mRNA is expressed in both germ line and somatic tissues and appears to be ubiquitous. The MOG-1 DEAH-box protein is most closely related to proteins essential for splicing in the yeast Saccharomyces cerevisiae, but splicing appears to occur normally in a mog-1-null mutant. In addition to its involvement in the sperm-oocyte switch and control of fem-3, zygotic mog-1 is required for robust germ line proliferation and for normal growth during development. We suggest that mog-1 plays a broader role in RNA regulation than previously considered.  (+info)

The nuclear receptor superfamily has undergone extensive proliferation and diversification in nematodes. (2/700)

The nuclear receptor (NR) superfamily is the most abundant class of transcriptional regulators encoded in the Caenorhabditis elegans genome, with >200 predicted genes revealed by the screens and analysis of genomic sequence reported here. This is the largest number of NR genes yet described from a single species, although our analysis of available genomic sequence from the related nematode Caenorhabditis briggsae indicates that it also has a large number. Existing data demonstrate expression for 25% of the C. elegans NR sequences. Sequence conservation and statistical arguments suggest that the majority represent functional genes. An analysis of these genes based on the DNA-binding domain motif revealed that several NR classes conserved in both vertebrates and insects are also represented among the nematode genes, consistent with the existence of ancient NR classes shared among most, and perhaps all, metazoans. Most of the nematode NR sequences, however, are distinct from those currently known in other phyla, and reveal a previously unobserved diversity within the NR superfamily. In C. elegans, extensive proliferation and diversification of NR sequences have occurred on chromosome V, accounting for > 50% of the predicted NR genes.  (+info)

Reticulate evolution and the origins of ribosomal internal transcribed spacer diversity in apomictic Meloidogyne. (3/700)

Among root knot nematodes of the genus Meloidogyne, the polyploid obligate mitotic parthenogens M. arenaria, M. javanica, and M. incognita are widespread and common agricultural pests. Although these named forms are distinguishable by closely related mitochondrial DNA (mtDNA) haplotypes, detailed sequence analyses of internal transcribed spacers (ITSs) of nuclear ribosomal genes reveal extremely high diversity, even within individual nematodes. This ITS diversity is broadly structured into two very different groups that are 12%-18% divergent: one with low diversity (< 1.0%) and one with high diversity (6%-7%). In both of these groups, identical sequences can be found within individual nematodes of different mtDNA haplotypes (i.e., among species). Analysis of genetic variance indicates that more than 90% of ITS diversity can be found within an individual nematode, with small but statistically significant (5%-10%; P < 0.05) variance distributed among mtDNA lineages. The evolutionarily distinct parthenogen M. hapla shows a similar pattern of ITS diversity, with two divergent groups of ITSs within each individual. In contrast, two diploid amphimictic species have only one lineage of ITSs with low diversity (< 0.2%). The presence of divergent lineages of rDNA in the apomictic taxa is unlikely to be due to differences among pseudogenes. Instead, we suggest that the diversity of ITSs in M. arenaria, M. javanica, and M. incognita is due to hybrid origins from closely related females (as inferred from mtDNA) and combinations of more diverse paternal lineages.  (+info)

Acoel flatworms: earliest extant bilaterian Metazoans, not members of Platyhelminthes. (4/700)

Because of their simple organization the Acoela have been considered to be either primitive bilaterians or descendants of coelomates through secondary loss of derived features. Sequence data of 18S ribosomal DNA genes from non-fast evolving species of acoels and other metazoans reveal that this group does not belong to the Platyhelminthes but represents the extant members of the earliest divergent Bilateria, an interpretation that is supported by recent studies on the embryonic cleavage pattern and nervous system of acoels. This study has implications for understanding the evolution of major body plans, and for perceptions of the Cambrian evolutionary explosion.  (+info)

Characterization of endonuclease activity from excretory/secretory products of a parasitic nematode, Trichinella spiralis. (5/700)

Double-stranded endonuclease activity was demonstrated for the first time in the excretory/secretory (ES) products of a parasitic nematode, Trichinella spiralis, which can reorganize host muscle cells. The endonuclease introduced double-stranded breaks to the native DNA. The ES double-stranded endonuclease(s) was sequence nonspecific, with a pH optimum below 6, and required divalent cations as a cofactor. Its activity was inhibited by the Zn2+ ion. It was detected mainly in the ES products of the infective-stage larvae of T. spiralis collected at 37 degrees C and was present in much smaller amounts in samples collected at 43 degrees C and in the products of T. pseudospiralis, a nonencapsulated species. The activity of endonuclease was blocked by antibodies against ES products. Zymographic analysis showed that the endonuclease activity was associated with at least three molecular forms, designated approximately 25, 30 and 58 kDa, respectively.  (+info)

The C. elegans homeodomain gene unc-42 regulates chemosensory and glutamate receptor expression. (6/700)

Genes that specify cell fate can influence multiple aspects of neuronal differentiation, including axon guidance, target selection and synapse formation. Mutations in the unc-42 gene disrupt axon guidance along the C. elegans ventral nerve cord and cause distinct functional defects in sensory-locomotory neural circuits. Here we show that unc-42 encodes a novel homeodomain protein that specifies the fate of three classes of neurons in the Caenorhabditis elegans nervous system: the ASH polymodal sensory neurons, the AVA, AVD and AVE interneurons that mediate repulsive sensory stimuli to the nematode head and anterior body, and a subset of motor neurons that innervate head and body-wall muscles. unc-42 is required for the expression of cell-surface receptors that are essential for the mature function of these neurons. In mutant animals, the ASH sensory neurons fail to express SRA-6 and SRB-6, putative chemosensory receptors. The AVA, AVD and AVE interneurons and RME and RMD motor neurons of unc-42 mutants similarly fail to express the GLR-1 glutamate receptor. These results show that unc-42 performs an essential role in defining neuron identity and contributes to the establishment of neural circuits in C. elegans by regulating the transcription of glutamate and chemosensory receptor genes.  (+info)

Analysis of calsequestrin gene expression using green fluorescent protein in Caenorhabditis elegans. (7/700)

The calsequestrin gene of Caenorhabditis elegans is expressed in body-wall muscle cells during muscle development. In order to study the body-wall muscle specific regulation of the calsequestrin gene expression, approximately 2 kb upstream sequences of the calsequestrin gene were analyzed. Transcriptional fusion constructs utilizing green fluorescent protein as a reporter gene were made and microinjected to produce germ-line transformed transgenic C. elegans. The expression of green fluorescent protein was observed in the body-wall muscles of live transgenic animals under fluorescence microscopy. Deletion analyses of upstream sequences have revealed a putative promoter sequence and a regulatory element which appeared to enhance reporter gene expression. Both sequence elements are juxtaposed to constitute a 260 bp regulatory region approximately 260 bp upstream from the putative translational initiation codon. Several possible binding sites for transcription factors were identified including the sites for YY1 and NF-W2, a muscle specific zinc finger transcription factor, and an ubiquitous enhancer binding protein, respectively. Interestingly, this region also contains a 20 bp sequence element identical to those found in the mouse dystrophin gene, which suggests a possible role of this regulatory region in muscle specific gene regulation.  (+info)

Control of schistosomiasis pathology by combination of Sm28GST DNA immunization and praziquantel treatment. (8/700)

Today the control of schistosomiasis infection relies only on the use of praziquantel (PZQ) chemotherapy. However, PZQ treatment cannot prevent reinfection and progressive development of the pathology. We assessed in a mouse model the efficiency of a combined therapy, based on the combination of PZQ chemotherapy with Schistosoma mansoni 28-kDa glutathion S-transferase (Sm28GST) DNA vaccination, designed to limit the pathology. Following this combined therapy, the long-term survival of the mice was significantly enhanced in comparison with the survival of mice either vaccinated only or treated with PZQ only. In addition, the development of the pathology observed in the control groups was almost completely prevented in the vaccinated-PZQ-treated mice and was associated with a dramatic reduction of egg deposition in the tissues. We showed that PZQ treatment induced the unmasking of the native GST enzyme at the surface of the worms, thus permitting its neutralization by the antibodies raised by DNA immunization. This study provides insights into the synergistic mechanisms involved in an immunointervention strategy associated with chemotherapy for the control of a chronic infection and its associated pathology.  (+info)

Leandro X. et, al, Quantitative Proteomics of Enriched Esophageal and Gut Tissues from the Human Blood Fluke Schistosoma mansoni Pinpoints Secreted Proteins for Vaccine Development, Nov. 15, 2019.. Schistosomes are blood-dwelling helminth parasites that cause schistosomiasis, a debilitating disease resulting in inflammation and, in extreme cases, multiple organ damage. Major challenges to control the transmission persist, and the discovery of protective antigens remains of critical importance for vaccine development. Rhesus macaques can self-cure following schistosome infection, generating antibodies that target proteins from the tegument, gut, and esophagus, the last of which is the least investigated. We developed a dissection technique that permitted increased sensitivity in a comparative proteomics profiling of schistosome esophagus and gut. Proteome analysis of the male schistosome esophagus identified 13 proteins encoded by microexon genes ...

Septins are guanosine-5-triphosphate-binding proteins involved in wide-ranging cellular processes including cytokinesis, vesicle trafficking, membrane remodelling and scaffolds, and with diverse binding partners. Precise roles for these structural proteins in most processes often remain elusive. Identification of small molecules that inhibit septins could aid in elucidating the functions of septins and has become increasingly important, including the description of roles for septins in pathogenic phenomena such as tumorigenesis. The plant growth regulator forchlorfenuron, a synthetic cytokinin known to inhibit septin dynamics, likely represents an informative probe for septin function. This report deals with septins of the human blood fluke Schistosoma mansoni and their interactions with forchlorfenuron. Recombinant forms of three schistosome septins, SmSEPT5, SmSEPT7.2 and SmSEPT10, interacted with forchlorfenuron, leading to rapid polymerization of filaments. Culturing developmental stages ...

Above: A nematode seen under a microscope. UF/IFAS photo by Tyler Jones.. A parasite is an organism that lives on or inside of another organism, weakening its host but usually not killing it. This feature distinguishes it from a parasitoid, which typically does kill its host.. Words related to parasite include parasitic (adjective), parasitism (noun) and parasitize (verb). Obligate parasitism occurs when an organism can only survive by its parasitic relationships with another organism.. Plant-parasitic nematodes are one example of a parasitic bug. These nematodes are very small and may only be visible with a microscope. Like other nematodes, plant-parasitic nematodes live in the soil, where they feed on plants.. Many of these parasitic nematodes attack plants from the outside with a spear-like body part called a stylet. Because of this behavior we call them ectoparasites, parasites that live on the outside of their host.. Other nematodes live inside a plant, making them endoparasites. Root-knot ...

abstract = {We have identified and characterized a Macrophage Migration Inhibitory Factor (MIF) family member in the Lophotrochozoan invertebrate, Biomphalaria glabrata, the snail intermediate host of the human blood fluke Schistosoma mansoni. In mammals, MIF is a widely expressed pleiotropic cytokine with potent pro-inflammatory properties that controls cell functions such as gene expression, proliferation or apoptosis. Here we show that the MIF protein from B. glabrata (BgMIF) is expressed in circulating immune defense cells (hemocytes) of the snail as well as in the B. glabrata embryonic (Bge) cell line that has hemocyte-like features. Recombinant BgMIF (rBgMIF) induced cell proliferation and inhibited NO-dependent p53-mediated apoptosis in Bge cells. Moreover, knock-down of BgMIF expression in Bge cells interfered with the in vitro encapsulation of S. mansoni sporocysts. Furthermore, the in vivo knock-down of BgMIF prevented the changes in circulating hemocyte populations that occur in ...
Two species-specific PCR primer pairs were developed for identifying the two nematode species, Bursaphelenchus xylophilus and B. mucronatus. The primer pairs were developed from the sequence of ribosomal DNA (rDNA) repeats to produce DNA fragments of different lengths by PCR amplification. The DNA fragments for B. mucronatus and B. xylophilus were 210 bp and 557 bp, respectively. When mixed, neither primer pair inhibited the PCR amplification of the other. Five isolates of B. xylophilus and four isolates of B. mucronatus showed different band profiles of PCR products between the two species, but identical profiles among isolates of the same species.
Pine wilt disease (PWD) is a complex disease integrating three major agents: the pathogenic agent, the pinewood nematode Bursaphelenchus xylophilus; the insect-vector Monochamus spp.; and the host pine tree, Pinus sp. Since the early 80s, the notion that another pathogenic agent, namely bacteria, may play a role in PWD has been gaining traction, however the role of bacteria in PWD is still unknown. The present work supports the possibility that some B. xylophilus-associated bacteria may play a significant role in the development of this disease. This is inferred as a consequence of: (i) the phenotypic characterization of a collection of 35 isolates of B. xylophilus-associated bacteria, in different tests broadly used to test plant pathogenic and plant growth promoting bacteria, and (ii) greenhouse experiments that infer the pathogenicity of these bacteria in maritime pine, Pinus pinaster. The results illustrate the presence of a heterogeneous microbial community associated with B. xylophilus and the

Bursaphelenchus luxuriosae n. sp. is described and figured. Specimens were collected from a 2-week-old culture on Botrytis cinerea. The new species is characterised by a body length of 897 (710-1159) μm in the female and 745 (621-887) μm in the male, relatively robust body (a = 33-39 in the female and 27-30 in the male), stylet ca 14 (11-16) μm long, four lines in the lateral field, the large (27-30 μm) arcuate spicule with a terminal cucullus, seven (2 + 1 + 2 + 2) male caudal papillae, the long, well developed vulval flap and the shape of the female tail which is long, tapered, and ventrally bent when killed by heat with an irregular or roughened dorsal contour near the tip and an irregular terminus. The new species is considered to belong to the Bursaphelenchus xylophilus group of the genus Bursaphelenchus and is most closely related to B. conicaudatus and B. fraudulentus in spicule shape, vulval flap and 'a' values of males and females. It is easily distinguished from these two species

Pine wilt disease (PWD) caused by pine wood nematode (PWN), Bursaphelenchus xylophilus, is the most destructive diseases of pine and poses a threat of serious economic losses worldwide. Although several of the mechanisms involved in disease progression have been discovered, the molecular response of Pinus massoniana to PWN infection has not been explored. We constructed four subtractive suppression hybridization cDNA libraries by taking time-course samples from PWN-inoculated Masson pine trees. One-hundred forty-four significantly differentially expressed sequence tags (ESTs) were identified, and 124 high-quality sequences with transcriptional features were selected for gene ontology (GO) and individual gene analyses. There were marked differences in the types of transcripts, as well as in the timing and levels of transcript expression in the pine trees following PWN inoculation. Genes involved in signal transduction, transcription and translation and secondary metabolism were highly expressed after 24
Supplementary MaterialsTable S1: Gene Ontology mappings for clusters. expansin proteins. Introduction Expressed sequence tags (ESTs) have proven to be one of the most rapid routes to gene discovery of any organism for which a cDNA library is available [1]. In addition, large-scale EST analysis can be used to estimate gene expression levels in specific life stages or tissues and are useful tools for annotation of genome sequences [1], [2]. EST analysis has been widely applied to study the biology of nematodes. Over 1.5 million ESTs from more than 63 species, including free-living nematodes, animal-parasitic and plant-parasitic species are available in dbEST (GenBank, 1 October 2012). To date, over 125,000 EST sequences from twenty different plant-parasitic nematodes are in dbEST. This information is of great significance for studying nematode biology, especially for the identification of effectors. Plant-parasitic nematode effectors, defined Maraviroc distributor here as proteins secreted by the ...

Written By Jenny Pavlovic. We lost Bandit to multiple myeloma in March, and our little pack continues to find its way. When Bandits body was failing and I realized he was in pain, it became apparent that he was ready to go. But I could tell he was concerned about how we would manage without him. So we spent time with him doing things he wanted to do for one last time, and cherished our last hours together. I reassured him that we didnt want him to be in pain any longer, and that somehow we would get along without him. Bandit wanted us to be happy and celebrate life.. Australian Cattle Dogs usually live longer than ten years, so whenever I begin to wish that wed had more time, I remember that a miracle brought us together in the first place. One step this way or that and our life together would not have happened at all. Im grateful we had that chance meeting.. Over the past ten years, I think Bandit has influenced my life more than any other being. We lived together day in and day out. He ...

  • Nowadays, one of the most prevalent zoonotic diseases is infection with helminth parasites, which infect about one-third of the human population worldwide. (
  • Infection with helminths usually tends to be chronic rather than acute infection, although there can be acute manifestations after initial infection in naive hosts. (
  • To dissect the mechanisms by which helminths modulate the host's response to enteric bacteria and bacteria-mediated intestinal inflammation, we have recently established a coinfection model and shown that coinfection with the helminth Heligmosomoides polygyrus exacerbates colitis induced by infection with the Gram-negative bacterial pathogen Citrobacter rodentium . (
  • These results demonstrate that helminth infection can impair host protection against concurrent enteric bacterial infection and promote bacteria-induced intestinal injury through a mechanism that involves the induction of alternatively activated macrophages. (
  • Helminth infection has been shown to dampen Th1 reactions to other infections ( 1 , 2 , 3 , 4 ). (

  • Helminth infection suppresses T-cell immune response to HIV-DNA-based vaccine in mice. (
  • We find that after helminth infection, or immunization with helminth antigens, reactive lymphoid organs of 4get IL-4/GFP reporter mice contain populations of IL-4/GFP-expressing CD4 + T cells that display the TFH markers CXCR5, PD-1, and ICOS. (
  • Th2 cells and their associated cytokines IL-4 and IL-13 play a crucial role in promoting host survival during infection with parasitic helminths that have tissue-dwelling phases ( 8 ), and they can mediate expulsion of intestinal helminths ( 9 ). (
  • This helminth infection was recorded in Norht America dated up to 10,000 years B.P. (Moore et al. (
  • show that intestinal helminth infection, caused by parasitic worms, protects IBD-susceptible mice from developing the disease. (
  • The greatest incidence of each of these diseases is in sub-Saharan Africa, where helminth infection is endemic ( 1 , 2 ). (
  • To evaluate the influence of helminth infection on vaccines, we can evaluate the ability to induce vaccine-specific immune responses in helminth-infected recipients or in recipients who have been treated with immune-biasing helminth antigens ( 11 - 13 ). (
  • Specifically, helminth infection has been shown to suppress immune responses to a Th1-type vaccine and impair the expansion of pathogen-specific cytotoxic CD8 + T cell (cytotoxic T lymphocyte [CTL]) responses ( 18 - 20 ). (
  • showing suppression of tetanus-specific responses in schistosome-infected children ( 8 ), helminth infection may pose a significant problem for the development of virus-specific CTL and Th1-type HIV-1 vaccines ( 7 , 8 , 11 ). (
  • One method to overcome helminth-induced vaccine suppression is to identify vaccine vectors that are capable of producing vaccine-specific responses irrespective of helminth infection. (
  • Below this level, helminth infection in the community will progressively decline, ultimately to zero. (
  • Helminthiasis, also known as worm infection, is any macroparasitic disease of humans and other animals in which a part of the body is infected with parasitic worms, known as helminths. (
  • Many DNA viruses elicit host DDRs during infection and some viruses require the DDR for efficient replication. (
  • Given that E2F activity is often deregulated by infection with DNA viruses, these observations raise the possibility that an E2F1-mediated mechanism of DDR activation may be conserved among DNA viruses. (
  • In Ethiopia, the prevalence and distribution of helminth infection varies by different exposing risk factors. (
  • Schistosome infection and soil-transmitted helminths (STHs) are major public health problems in many developing countries where they contribute to the suffering of populations living in poor settings. (
  • A systematic optimization of intestinal digestion protocols allows for the isolation and high-dimensional flow cytometric analysis of intestinal immune cells during murine helminth infection. (
  • Helminths are multicellular parasitic organisms belonging to a diverse taxonomic group of metazoans that compromise the phylum Platyhelminths, known as flatworms, including cestodes and trematodes, and Nematoda, known as roundworms, including Ascaris , hookworm, whipworms, filarial parasites, and others. (

  • Considering the profound immune activation and dysregulation induced by helminth parasites, the overlapping geographic distributions of helminth and bacterial infections, and the potential to modulate bacteria-associated intestinal inflammation, we have recently established a coinfection model system to facilitate detailed analysis of the combined effects of helminth and bacterial pathogens on host responses. (
  • Owing to the control of insect vector populations, the safe disposal of human excrement, and the availability of efficacious drugs, helminth parasites have been largely eradicated as a public health concern in developed countries. (
  • One consequence of this geopolitical segregation is that most of the world's pharmaceutical industries do not support active research and development programs on helminth parasites that cause human disease. (
  • Many helminth parasites are long-lived and cause chronic infections. (
  • Amongst these parasites, soil-transmitted helminths (STHs), including Ancylostoma duodenale and Necator americanus (hookworms), Ascaris sp. (
