Regulation of body length and male tail ray pattern formation of Caenorhabditis elegans by a member of TGF-beta family. (1/1944)

We have identified a new member of the TGF-beta superfamily, CET-1, from Caenorhabditis elegans, which is expressed in the ventral nerve cord and other neurons. cet-1 null mutants have shortened bodies and male tail abnormal phenotype resembling sma mutants, suggesting cet-1, sma-2, sma-3 and sma-4 share a common pathway. Overexpression experiments demonstrated that cet-1 function requires wild-type sma genes. Interestingly, CET-1 appears to affect body length in a dose-dependent manner. Heterozygotes for cet-1 displayed body lengths ranging between null mutant and wild type, and overexpression of CET-1 in wild-type worms elongated body length close to lon mutants. In male sensory ray patterning, lack of cet-1 function results in ray fusions. Epistasis analysis revealed that mab-21 lies downstream and is negatively regulated by the cet-1/sma pathway in the male tail. Our results show that cet-1 controls diverse biological processes during C. elegans development probably through different target genes.  (+info)

Alzheimer's disease: clues from flies and worms. (2/1944)

Presenilin mutations give rise to familial Alzheimer's disease and result in elevated production of amyloid beta peptide. Recent evidence that presenilins act in developmental signalling pathways may be the key to understanding how senile plaques, neurofibrillary tangles and apoptosis are all biochemically linked.  (+info)

The Caenorhabditis elegans sex determination gene mog-1 encodes a member of the DEAH-Box protein family. (3/1944)

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)

Identification of a human HECT family protein with homology to the Drosophila tumor suppressor gene hyperplastic discs. (4/1944)

Use of the differential display technique to isolate progestin-regulated genes in T-47D human breast cancer cells led to identification of a novel gene, EDD. The cDNA sequence contains a 2799 amino acid open reading frame sharing 40% identity with the predicted 2894 amino acid product of the Drosophila melanogaster tumor suppressor gene hyperplastic discs, while the carboxy-terminal 889 amino acids show 96% identity to a rat 100 kDa HECT domain protein. EDD mRNA was progestin-induced in T-47D cells and was highly abundant in testes and expressed at moderately high levels in other tissues, suggesting a broad role for EDD. Anti-EDD antibodies immunoprecipitated an approximately 300 kDa protein from T-47D cell lysates. HECT family proteins function as E3 ubiquitin-protein ligases, targeting specific proteins for ubiquitin-mediated proteolysis. EDD is likely to function as an E3 as in vitro translated protein bound ubiquitin reversibly through a conserved HECT domain cysteine residue. EDD was localized by FISH to chromosome 8q22, a locus disrupted in a variety of cancers. Given the homology between EDD and the hyperplastic discs protein, which is required for control of imaginal disc growth in Drosophila, EDD potentially has a role in regulation of cell proliferation or differentiation.  (+info)

The Caenorhabditis elegans gene ham-2 links Hox patterning to migration of the HSN motor neuron. (5/1944)

The Caenorhabditis elegans HSN motor neurons permit genetic analysis of neuronal development at single-cell resolution. The egl-5 Hox gene, which patterns the posterior of the embryo, is required for both early (embryonic) and late (larval) development of the HSN. Here we show that ham-2 encodes a zinc finger protein that acts downstream of egl-5 to direct HSN cell migration, an early differentiation event. We also demonstrate that the EGL-43 zinc finger protein, also required for HSN migration, is expressed in the HSN specifically during its migration. In an egl-5 mutant background, the HSN still expresses EGL-43, but expression is no longer down-regulated at the end of the cell's migration. Finally, we find a new role in early HSN differentiation for UNC-86, a POU homeodomain transcription factor shown previously to act downstream of egl-5 in the regulation of late HSN differentiation. In an unc-86; ham-2 double mutant the HSNs are defective in EGL-43 down-regulation, an egl-5-like phenotype that is absent in either single mutant. Thus, in the HSN, a Hox gene, egl-5, regulates cell fate by activating the transcription of genes encoding the transcription factors HAM-2 and UNC-86 that in turn individually control some differentiation events and combinatorially affect others.  (+info)

Patterning of Caenorhabditis elegans posterior structures by the Abdominal-B homolog, egl-5. (6/1944)

The Caenorhabditis elegans body axis, like that of other animals, is patterned by the action of Hox genes. In order to examine the function of one C. elegans Hox gene in depth, we determined the postembryonic expression pattern of egl-5, the C. elegans member of the Abdominal-B Hox gene paralog group, by means of whole-mount staining with a polyclonal antibody. A major site of egl-5 expression and function is in the epithelium joining the posterior digestive tract with the external epidermis. Patterning this region and its derived structures is a conserved function of Abd-B paralog group genes in other animals. Cells that initiate egl-5 expression during embryogenesis are clustered around the presumptive anus. Expression is initiated postembryonically in four additional mesodermal and ectodermal cell lineages or tissues. Once initiated in a lineage, egl-5 expression continues throughout development, suggesting that the action of egl-5 can be regarded as defining a positional cell identity. A variety of cross-regulatory interactions between egl-5 and the next more anterior Hox gene, mab-5, help define the expression domains of their respective gene products. In its expression in a localized body region, function as a marker of positional cell identity, and interactions with another Hox gene, egl-5 resembles Hox genes of other animals. This suggests that C. elegans, in spite of its small cell number and reproducible cell lineages, may not differ greatly from other animals in the way it employs Hox genes for regional specification during development.  (+info)

Reverse genetic analysis of Caenorhabditis elegans presenilins reveals redundant but unequal roles for sel-12 and hop-1 in Notch-pathway signaling. (7/1944)

Mutations in the human presenilin genes PS1 and PS2 cause early-onset Alzheimer's disease. Studies in Caenorhabditis elegans and in mice indicate that one function of presenilin genes is to facilitate Notch-pathway signaling. Notably, mutations in the C. elegans presenilin gene sel-12 reduce signaling through an activated version of the Notch receptor LIN-12. To investigate the function of a second C. elegans presenilin gene hop-1 and to examine possible genetic interactions between hop-1 and sel-12, we used a reverse genetic strategy to isolate deletion alleles of both loci. Animals bearing both hop-1 and sel-12 deletions displayed new phenotypes not observed in animals bearing either single deletion. These new phenotypes-germ-line proliferation defects, maternal-effect embryonic lethality, and somatic gonad defects-resemble those resulting from a reduction in signaling through the C. elegans Notch receptors GLP-1 and LIN-12. Thus SEL-12 and HOP-1 appear to function redundantly in promoting Notch-pathway signaling. Phenotypic analyses of hop-1 and sel-12 single and double mutant animals suggest that sel-12 provides more presenilin function than does hop-1.  (+info)

Differential serodiagnosis for cystic and alveolar echinococcosis using fractions of Echinococcus granulosus cyst fluid (antigen B) and E. multilocularis protoscolex (EM18). (8/1944)

Echinococcus granulosus cyst fluid and E. multilocularis protoscolex extract were fractionated by a single step of preparative isoelectric focusing, resulting in an antigen B-rich fraction (8-kD) and an Em18-rich fraction, respectively. The usefulness of both fractions for differential serodiagnosis of cystic (CE) and alveolar (AE) echinococcosis was evaluated by a large-scale immunoblot analysis on a battery of 354 serum samples. These included 66 from AE patients originating from four different endemic areas, 173 from CE patients originating from seven different endemic areas, 71 from patients with other parasitic diseases, 15 from patients with hepatomas, and 29 from healthy individuals. In an immunoblot with the antigen B-rich fraction, 92% (158 of 173) of the CE sera as well as 79% (52 of 66) of the AE sera reacted with the 8-kD subunit. No cross-reactivity occurred with any sera from patients with cysticercosis, other parasitic diseases, or with hepatomas, or from healthy controls. In an immunoblot with the Em18-rich fraction, all but two sera from AE patients (64 of 66, 97%) recognized Em18, and only nine of 34 CE sera from China reacted with it. All other (139) CE sera from six other countries were negative as were all (115) other non-echinococcosis sera. These findings indicate that antigen B (8-kD) is not species-specific for E. granulosus but is genus-specific for Echinococcus, and that the Em18 antigen is a reliable serologic marker for species-specific differentiation of AE from CE.  (+info)

Preferred Name: Recombinant Nematode Anticoagulant Protein c2 Definition: An 85-amino acid recombinant peptide derived from protein c2 of the hemophagocytic hookworm Ancylostoma caninum (a common canine parasite) with anticoagulant activity. Recombinant nematode anticoagulant protein c2 (rNAPc2) binds to circulating activated factor X (FXa) or zymogen factor X (FX) to form a binary complex which subsequently binds to and inhibits membrane-bound activated factor VII/tissue factor complex (FVIIa/TF). When administered prophylactically, this agent may reduce the incidence of deep venous thrombosis without hemostatic compromise. Because rNAPc2 inhibits the formation of the FVIIa/TF protease complex, which may play a role in the cellular signaling of both metastatic and angiogenic processes, it may impede tumor progression.

Excretory/secretory proteins (ESPs) play a major role in parasitic infection as they are present at the host-parasite interface and regulate host immune system. In case of parasitic helminths, transcriptomics has been used extensively to understand the molecular basis of parasitism and for developing novel therapeutic strategies against parasitic infections. However, none of transcriptomic studies have extensively covered ES protein prediction for identifying novel therapeutic targets, especially as parasites adopt non-classical secretion pathways. We developed a semi-automated computational approach for prediction and annotation of ES proteins using transcriptomic data from next generation sequencing platforms. For the prediction of non-classically secreted proteins, we have used an improved computational strategy, together with homology matching to a dataset of experimentally determined parasitic helminth ES proteins. We applied this protocol to analyse 454 short reads of parasitic nematode,
Calpains are calcium-dependent cysteine proteases involved in signal transduction in a variety of cellular processes. A functional calpain protein consists of an invariant small subunit and 1 of a family of large subunits. CAPN5 is one of the large subunits. Unlike some of the calpains, CAPN5 and CAPN6 lack a calmodulin-like domain IV. Because of the significant similarity to Caenorhabditis elegans sex determination gene tra-3, CAPN5 is also called as HTRA3. [provided by RefSeq, Jul 2008 ...
By design, sperm cells are small, motile, and transcriptionally inactive. Thus a key step in the developmental program of making a sperm involves prepackaging components that need to be synthesized before the turnoff of transcription and stored for later use. Nematode spermatogenesis provides an extreme example of this process; bulk transcription ceases prior to the meiotic divisions and translation ceases immediately after anaphase II. In particular, spermatocytes must synthesize and prepackage a small filament forming protein called the major sperm protein (MSP). Within mature nematode sperm, MSP serves both as the protein that drives sperm motility and as a signaling protein that triggers oocyte maturation and the physical process of ovulation. Our lab has recently identified several factors involved in both the assembly and sequestration of MSP into large, macromolecular structures called fibrous bodies. Furthermore, in a link to our cell division interests, mutants with defects in MSP ...

N2 - The crawling movement of nematode sperm requires coordination of leading edge protrusion with cell body retraction, both of which are powered by modulation of a cytoskeleton based on major sperm protein (MSP) filaments. We used a cell-free in vitro motility system in which both protrusion and retraction can be reconstituted, to identify two proteins involved in cell body retraction. Pharmacological and depletion-add back assays showed that retraction was triggered by a putative protein phosphatase 2A (PP2A, a Ser/Thr phosphatase activated by tyrosine dephosphorylation). Immunofluorescence showed that PP2A was present in the cell body and was concentrated at ...
The gene lin-11 is required for the asymmetric division of a vulval precursor cell type in the nematode Caenorhabditis elegans.

The vaccinia-related kinases (VRKs) are highly conserved throughout the animal kingdom and phosphorylate several chromatin proteins and transcription factors. In early Caenorhabditis elegans embryos, VRK-1 is required for proper nuclear envelope formation. In this work, we present the first investigation of the developmental role of VRKs by means of a novel C. elegans vrk-1 mutant allele. We found that VRK-1 is essential in hermaphrodites for formation of the vulva, uterus, and utse and for development and maintenance of the somatic gonad and thus the germ line. VRK-1 regulates anchor cell polarity and the timing of anchor cell invasion through the basement membranes separating vulval and somatic gonadal cells during the L3 larval stage. VRK-1 is also required for proper specification and proliferation of uterine cells and sex myoblasts. Expression of the fibroblast growth factor-like protein EGL-17 and its receptor EGL-15 is reduced in vrk-1 mutants, suggesting that VRK-1 might act at least ...

Previously, we have shown that ES-62 mimics are efficacious in protecting against disease in mouse models of rheumatoid arthritis, systemic ...
Because planarians can regenerate a complete body from a tissue fragment they present a powerful system in which to study cell, tissue and organ regeneration, and to look for conserved developmental mechanisms. Peter Reddien and colleagues now describe a regulatory programme for the regeneration of the planarian Schmidtea mediterranea excretory system, the protonephridia (see p. 4387). The S. mediterranea protonephridia consists of tubules, which are dispersed throughout the animals body, two types of tubule-associated cells, and ciliated terminal cells, which drive filtration from the extracellular space into the tubule lumen. The researchers use RNAi screening assays and microarray analyses to show that Six1/2-2, POU2/3, hunchback, Eya, Sal1 and Osr, which encode transcriptional regulators, are involved in protonephridia regeneration. Notably, apart from hunchback, all these genes are also required for vertebrate kidney development. Moreover, the researchers show that planarian and vertebrate ...

You have something in common with a flatworm: more than 100 mucosal proteins. In a recent paper in Molecular and Cellular Proteomics, researchers showed that the freshwater planarian Schmidtea mediterranea has proteins in its mucous coating that are strikingly similar to ones in human mucus and other secretions, such as tear fluid.. The work grew out of a lab rotation project by a graduate student, Donald Bocchinfuso at the University of Toronto, who set up a collaboration between the laboratories of Michael Moran (an expert in mass spectrometry) and Bret Pearson (an expert in planarians) at the Hospital For Sick Children in Toronto, Canada. Bocchinfuso was interested in analyzing the mucous coating on the worms by MS.. The idea to compare worms before and after removing their mucous coating started out as a simple technical step, says Moran. However, it grew to become a central part of the study, in part because we are at a childrens hospital and, therefore, have an awareness of the huge ...

(Medical Xpress)-Doctor Joel Weinstock, a parasitologist at Tufts Medical Center in a commentary piece published in the journal Nature, describes work that he and colleagues have been involved in that focuses on studying the possibility of introducing parasitic worms into the guts of patients suffering from autoimmune diseases such as Crohns disease. The thinking he says, is that modern hygienic lifestyles may be contributing to such diseases and that reintroducing parasitic worms and perhaps certain bacteria into the gut may restore a natural balance in the gut and relieve patients of such symptoms as chronic diarrhea, bleeding and infections.

Parasitic worms in humans are often associated with travel, but you can also get them at home. These organisms live in and feed off a living host, like a human. They arent always visible to the naked eye but are treatable. Heres what you should know about transmission, treatment, and how to avoid being a host.
Parasitic worms may be useful in treating lung disease and healing wounds, according to a study published online today (Jan.15) in Nature Medicine.

As for PKC, we found and identified ASIP, atypical PKC-specific interacting protein, as a physiological binding partner of atypical PKJKC isotypes. ASIP is a PDZ domain-containing adaptor-like protein and is the mammalian orthologue of C. elegans PAR-3 and Drosophila Bazooka, both of which are involved in the establishment of cell polarity. ASIP as well as aPKC localize to the tight junctions of vertebrate epithelial cells and are required for the establishment of epithelial cell polarith that include the development of epithelia-specific junctional structures ...
Lead researcher, Dr. Aaron Jex, Faculty of Veterinary Science, said, We know that humans infected with the harmless, pig whipworm can have significantly reduced symptoms linked to autoimmune diseases. And now we have the genetic sequence of the worm, it opens the door to future human drug designs and treatment.
Parasitic worms infect millions of people in the developing world, by following chemical trails to their hosts. Isolating the substances that attract them is the key to finding cheap and practical ways of preventing infection. Throughout the day, our skins are constantly sending out messages that we can neither see nor hear. The message is…

TY - JOUR. T1 - The human GRB2 and Drosophila Drk genes can functionally replace the Caenorhabditis elegans cell signaling gene sem-5. AU - Stern, M. J.. AU - Marengere, L. E.M.. AU - Daly, R. J.. AU - Lowenstein, E. J.. AU - Kokel, M.. AU - Batzer, A.. AU - Olivier, P.. AU - Pawson, T.. AU - Schlessinger, J.. PY - 1993/1/1. Y1 - 1993/1/1. N2 - Mutations in the Caenorhabditis elegans gene sem-5 affect cell signaling processes involved in guiding a class of cell migrations and inducing vulval cell fates. The sem-5 sequence encodes a protein comprised almost exclusively of SH2 and SH3 domains (SH, src homology region) that are found together in many signaling proteins and nonreceptor tyrosine kinases. A human protein, GRB2, was identified by its ability to associate with the activated human epidermal growth factor receptor (hEGFR). The GRB2 and Sem-5 proteins share an identical architecture of their SH2 and SH3 domains and 58% amino acid sequence identity. Here we demonstrate that GRB2 and a ...
Author summary Infection with helminth parasites is known to be inversely associated with hyper-inflammatory disorders. While Schistosoma (S.) mansoni has been described to exert its down-modulatory effects on inflammation by inducing a network of regulatory immune cells such as regulatory B (Breg), the mechanisms of Breg cell induction remain unclear. Here, we use in vivo and in vitro approaches to show that antigens from S. mansoni eggs, among which the major glycoprotein IPSE/alpha-1, directly interact with splenic marginal zone B cells of mice which triggers them to produce the anti-inflammatory cytokine IL-10 and their capacity to induce regulatory T (Treg) cells. We also found that IPSE/alpha-1 induces IL-10 in human CD1d+ B cells, and that both natural and recombinant IPSE/alpha-1 are equally effective in driving murine and human Breg cells. Our study thus provides insight into the mechanisms of Breg cell induction by schistosomes, and an important step towards the development of helminth-based
Using our Illumina RNAseq approach, we identified hundreds of differentially regulated genes during different stages of head regeneration, and clustered them into groups according to their dynamic expression profiles (Figure 6c).. Among the genes that were strongly upregulated during the first few hours of regeneration were genes encoding putative homologues of mammalian inflammatory response genes. Gene_3164, for instance, encodes a putative tumor necrosis factor receptor (TNFR)-associated protein (TRAF). TRAFs interact with numerous members of the TNFR family and have a variety of tissue-specific functions. As TRAFs have been implicated in promoting the immune response after infections and wounding [42, 43], it is possible that similar proteins are also involved in the regulation of immune responses after decapitation in planarians. Reported RNAi phenotypes of putative TRAF-like genes in the planarian species D. japonica are pleiotropic [44]. Thus, the functions of putative planarian TRAFs, as ...
One of the most rapidly increasing human public health problems is obesity, whose sequelae like type-2 diabetes, represent continuously worsening, life-long conditions. Over the last 15 years, data have begun to emerge from human and more frequently, mouse studies, that support the idea that parasitic worm infection can protect against this condition. We have therefore investigated the potential of two synthetic small molecule analogues (SMAs) of the anti-inflammatory Acanthocheilonema viteae product ES-62, to protect against metabolic dysfunction in a C57BL/6 J mouse model of high calorie diet-induced obesity. We found weekly subcutaneous administration of the SMAs in combination (1 μg of each), starting one week before continuous exposure to high calorie diet (HCD), decreased fasting glucose levels and reversed the impaired glucose clearance observed in male mice, when measured at approximately 7 and 13 weeks after exposure to HCD. Fasting glucose levels were also-reduced in male mice fed a ...
Chitinasen sind wichtigen Moleküle im Lebenszyklus parasitischer Fadenwürmer und bedeutende Medikamenten- und Impfstoffziele. Hier wurden drei Chitinasesequenzen (I, II und III) durch Charakterisierung von 9 Klonen aus einer Genbank von Acanthocheilonema viteae gefunden. Die Anzahl der drei sehr homologen Chitinasegene wurde durch Southern-Blot bestätigt. Die größten Unterschiede sind in den Exons zu finden, die die Serin-Threonin-reiche Domäne der Chitinasen codieren. Diese Domäne ist in Sequenz III ca. 10fach länger als in Sequenz I. Sequenz I und III haben Eigenschaften eines transkribierten Genes: ein Startcodon, ein offener Leserahmen, ein Stopcodon und ein Polyadenylierungssignal. Sequenz II fehlt das erste Exon mit dem Startcodon. Bei Durchmusterung einer cDNA-Bibliothek adulter A. viteae Würmer bzw. L3 Stadien, sowie durch Reverser Transkriptase-PCR (RT-PCR) wurden in den Mikrofilarien, L3 und L4 Transkripte für Gen I gefunden, jedoch nicht für Gen III. Das N-terminale ...
Involved in several cell fate decisions that require cell-cell interactions. It is possible that lin-12 encodes a membrane-bound receptor for a signal that enables expression of the ventral uterine precursor cell fate. Activity in cell fate decisions and tumorigenesis is negatively regulated by sel-10.
During the course of normal embryonic and post-embryonic development, 131 cells in a Caenorhabditis elegans hermaphrodite undergo programmed cell death. Loss of function mutations in either of the genes ced-3 or ced-4 abolish cell deaths, enabling these undead cells to survive and be incorporated into the adult with no obvious deleterious consequences. Ultrastructural reconstructions have shown that undead cells exhibit many differentiated characteristics. Most of the reconstructed cells appeared to be neurons with all the characteristic features associated with such cells, such as processes, synaptic vesicles and presynaptic specializations. However, clear morphological differences were seen among the undead neurons, suggesting a diversity of cell type. One of the reconstructed cells was a rectal epithelial cell, which had displaced its lineal sister that normally functions in this role. Removal of the ability to undergo programmed cell death by mutation therefore reveals a diversity of ...
BACKGROUND: Caenorhabditis elegans has traditionally been used as a model for studying nematode biology, but its small size limits the ability for researchers to perform some experiments such as high-throughput tissue-specific gene expression studies. However, the dissection of individual tissues is possible in the parasitic nematode Ascaris suum due to its relatively large size. Here, we take advantage of the recent genome sequencing of Ascaris suum and the ability to physically dissect its separate tissues to produce a wide-scale tissue-specific nematode RNA-seq datasets, including data on three non-reproductive tissues (head, pharynx, and intestine) in both male and female worms, as well as four reproductive tissues (testis, seminal vesicle, ovary, and uterus). We obtained fundamental information about the biology of diverse cell types and potential interactions among tissues within this multicellular organism. METHODOLOGY/PRINCIPAL FINDINGS: Overexpression and functional enrichment analyses ...
Planarians (flatworms) can regenerate from irregularly shaped fragments. During regeneration, new tissue forms at the wound and existing tissues are remodelled to make a complete, symmetrical animal. How is this amazing feat achieved? On p. 4043, Alejandro Sánchez Alvarados group report that BMP signalling regulates several aspects of regeneration in the planarian Schmidtea mediterranea. The researchers use RNAi knockdown to investigate the role of smedolloid-1 (a BMP1/Tolloid-like gene), smedsmad4-1 (a SMAD4-like gene) and smedbmp4-1 (a BMP2/4/DPP-like gene) in regeneration. These experiments show that BMP signalling is involved in the formation and dorsal-ventral (DV) patterning of new tissues at the reset midline of a regenerating fragment. Additional knockdown experiments indicate that BMP signalling also maintains the DV pattern in undamaged adult tissue. These and other results lead the researchers to propose that BMP signalling regulates the dorsal midline of planarians and that the ...

CELL migration is a fundamental event in the development of nervous systems. In the vertebrate central nervous system, neurons and neuroblasts migrate radially to populate distinct layers in the cerebellar and cerebral cortices, and neural crest cells migrate along distinct paths in the vertebrate embryo to give rise to the peripheral nervous system. The Q neuroblasts in Caenorhabditis elegans are a useful model to study the migration of neuroblasts and neurons in the anterior-posterior axis. The Q neuroblasts are a bilaterally symmetric pair of cells in the posterior-lateral region of the animal, with QR on the right side and QL on the left side (Sulston and Horvitz 1977). The Q neuroblasts are born in embryogenesis and are the sisters of the V5 hypodermal seam cells. By 5 hr after hatching, QR has migrated anteriorly and divided over the V4 seam cell, and QL has migrated posteriorly and divided over the V5 seam cell (Honigberg and Kenyon 2000; Chapman et al. 2008; Dyer et al. 2010). The ...
There are two likely explanations for the greater success of the GFP screen. First, nearly half of the mutants isolated in the direct screen were less than 10% Wit or Clr and would have been missed in the Wit and Clr screen. Second, several of the mutants developed slowly. The Wit phenotype is most easily scored in adult animals, while defects visualized by GFP could be scored in younger animals. In the Wit and Clr screen, mutants that are slow to reach adulthood might be lost among the next generation of nonmutant animals.. Three Syc mutants require the presence of kyIs5 to express the Cam phenotype: mutations in the syc genes result in defects in CAN cell migration only when kyIs5 is present (Figure 4). Mutations in each of the Syc genes results in weak (syc-1 and syc-3) or strong (syc-2) Unc phenotypes in the absence of the transgene, suggesting that the mutations disrupt the development or function of additional neurons. The effects on CAN migration are enhanced when the syc-3 mutation is ...

Some commonly used methods of processing larvae of Heterodera rostochiensis for microscopical examination cause changes in body and stylet size, greater than the difference between pathotypes. It is suggested that heat and cold formalin, which caused least change, should be the standard methods of killing and fixing larvae to be measured.
