The Caenorhabditis elegans mel-11 myosin phosphatase regulatory subunit affects tissue contraction in the somatic gonad and the embryonic epidermis and genetically interacts with the Rac signaling pathway. (1/189)

Caenorhabditis elegans embryonic elongation is driven by cell shape changes that cause a contraction of the epidermal cell layer enclosing the embryo. We have previously shown that this process requires a Rho-associated kinase (LET-502) and is opposed by the activity of a myosin phosphatase regulatory subunit (MEL-11). We now extend our characterization and show that mel-11 activity is required both in the epidermis during embryonic elongation and in the spermatheca of the adult somatic gonad. let-502 and mel-11 reporter gene constructs show reciprocal expression patterns in the embryonic epidermis and the spermatheca, and mutations of the two genes have opposite effects in these two tissues. These results are consistent with let-502 and mel-11 mediating tissue contraction and relaxation, respectively. We also find that mel-11 embryonic inviability is genetically enhanced by mutations in a Rac signaling pathway, suggesting that Rac potentiates or acts in parallel with the activity of the myosin phosphatase complex. Since Rho has been implicated in promoting cellular contraction, our results support a mechanism by which epithelial morphogenesis is regulated by the counteracting activities of Rho and Rac.  (+info)

Differential and inefficient splicing of a broadly expressed Drosophila erect wing transcript results in tissue-specific enrichment of the vital EWG protein isoform. (2/189)

In this report, we document an unusual mode of tissue-enriched gene expression that is primarily mediated by alternative and inefficient splicing. We have analyzed posttranscriptional regulation of the Drosophila erect wing gene, which provides a vital neuronal function and is essential for the formation of certain muscles. Its predominant protein product, the 116-kDa EWG protein, a putative transcriptional regulator, can provide all known erect wing-associated functions. Moreover, consistent with its function, the 116-kDa protein is highly enriched in neurons and is also observed transiently in migrating myoblasts. In contrast to the protein distribution, we observed that erect wing transcripts are present in comparable levels in neuron-enriched heads and neuron-poor bodies of adult Drosophila. Our analyses shows that erect wing transcript consists of 10 exons and is alternatively spliced and that a subset of introns are inefficiently spliced. We also show that the 116-kDa EWG protein-encoding splice isoform is head enriched. In contrast, bodies have lower levels of transcripts that can encode the 116-kDa protein and greater amounts of unprocessed erect wing RNA. Thus, the enrichment of the 116-kDa protein in heads is ensured by tissue-specific alternative and inefficient splicing and not by transcriptional regulation. Furthermore, this regulation is biologically important, as an increased level of the 116-kDa protein outside the nervous system is lethal.  (+info)

Interferon-gamma contributes to the normalcy of murine pregnancy. (3/189)

Uterine natural killer (uNK) cells are transient, large, heavily granulated, maternal lymphocytes present on the mesometrial side of the pregnant mouse uterus. These cells contribute to normal implantation site development. Cytokine production, particularly interferon (IFN)-gamma, is a major function of most NK cell subsets. In this study, uNK cells were assessed for IFN-gamma production. Local concentrations of IFN-gamma were measured in the mesometrial regions of murine implantation sites between Days 6 and 16 of gestation. IFN-gamma was detected by ELISA at all days studied in a random-bred (CD1) and an inbred (BALB/c) strain of immune-competent mouse and in two immune-deficient strains, SCID (NK(+), T(-), B(-)) and tgepsilon26 (NK(-), T(-), B(+)). Concentrations of IFN-gamma per implantation site peaked at Day 10 of gestation in NK(+) strains but were low and relatively constant in NK(-) mice. To evaluate the functions of IFN-gamma at murine implantation sites, pregnancy was studied in homozygously mated IFN-gamma(-/-) and IFN-gammaRalpha(-/-) mice and their congenic controls. Primiparous but not multiparous IFN-gamma(-/-) mice experienced significant fetal loss. Primiparous IFN-gammaRalpha(-/-) carried full litters to term. Implantation site pathology was demonstrated in both strains of gene-deleted mice by light microscopy and ultrastructurally. This included elevated numbers of uNK cells that contained fewer and smaller granules and, after Day 10 of gestation, progressive necrosis and loss of decidua. The presence of a fetus able to produce IFN-gamma did not modify the phenotype of pregnant IFN-gamma(-/-) mice. This study indicates that during murine pregnancy, uNK cells are the main source of IFN-gamma on the mesometrial side of the uterus and that IFN-gamma contributes to normal health of the midgestational decidua. Furthermore, evidence is presented that IFN-gamma-producing cells exist in mesometrial regions of implantation sites that are neither NK nor T cells.  (+info)

Expression of the insulin-like growth factor-1 gene and its receptor in preimplantation mouse embryos; is it a marker of embryo viability? (4/189)

Recent studies have demonstrated the importance of insulin-like growth factors (IGF) in mouse preimplantation development. We examined IGF-1 and IGF-1 receptor (IGF-1R) gene expression in a single blastomere of an early mouse embryo and compared it with subsequent embryo development in culture. Fertilized eggs and 2-cell embryos were obtained by tubal flushing in superovulated and mated female mice. Single cells were removed from embryos at cleavage stage between 3 and 8 cells using the standard embryo biopsy techniques. Individual blastomeres from each embryo were then assayed for the presence of IGF-1 and IGF-1R mRNA using reverse transcription-polymerase chain reaction. The biopsied embryos were washed in medium and placed in co-culture with murine endometrial cells. Embryonic development in culture was assessed and blastocyst grading was performed. IGF-1 gene expression was then examined for an association with in-vitro development. Eighty-seven embryos were biopsied. IGF-1R gene expression was detected in the majority of embryos tested and IGF-1 gene expression was detected in 34 of 81 (42%) embryos. A significant association between IGF-1 expression and blastocyst formation in vitro was found (P < 0.01). There was no association between IGF-1R expression and subsequent embryo development. We conclude that IGF-1 gene expression could potentially be used as a marker of embryo quality.  (+info)

Drosophila myc regulates cellular growth during development. (5/189)

Transcription factors of the Myc proto-oncogene family promote cell division, but how they do this is poorly understood. Here we address the functions of Drosophila Myc (dMyc) during development. Using mosaic analysis in the fly wing, we show that loss of dMyc retards cellular growth (accumulation of cell mass) and reduces cell size, whereas dMyc overproduction increases growth rates and cell size. dMyc-induced growth promotes G1/S progression but fails to accelerate cell division because G2/M progression is independently controlled by Cdc25/String. We also show that the secreted signal Wingless patterns growth in the wing primordium by modulating dMyc expression. Our results indicate that dMyc links patterning signals to cell division by regulating primary targets involved in cellular growth and metabolism.  (+info)

PPAR gamma is required for placental, cardiac, and adipose tissue development. (6/189)

The nuclear hormone receptor PPAR gamma promotes adipogenesis and macrophage differentiation and is a primary pharmacological target in the treatment of type II diabetes. Here, we show that PPAR gamma gene knockout results in two independent lethal phases. Initially, PPAR gamma deficiency interferes with terminal differentiation of the trophoblast and placental vascularization, leading to severe myocardial thinning and death by E10.0. Supplementing PPAR gamma null embryos with wild-type placentas via aggregation with tetraploid embryos corrects the cardiac defect, implicating a previously unrecognized dependence of the developing heart on a functional placenta. A tetraploid-rescued mutant surviving to term exhibited another lethal combination of pathologies, including lipodystrophy and multiple hemorrhages. These findings both confirm and expand the current known spectrum of physiological functions regulated by PPAR gamma.  (+info)

PPAR gamma mediates high-fat diet-induced adipocyte hypertrophy and insulin resistance. (7/189)

Agonist-induced activation of peroxisome proliferator-activated receptor gamma (PPAR gamma) is known to cause adipocyte differentiation and insulin sensitivity. The biological role of PPAR gamma was investigated by gene targeting. Homozygous PPAR gamma-deficient embryos died at 10.5-11.5 dpc due to placental dysfunction. Quite unexpectedly, heterozygous PPAR gamma-deficient mice were protected from the development of insulin resistance due to adipocyte hypertrophy under a high-fat diet. These phenotypes were abrogated by PPAR gamma agonist treatment. Heterozygous PPAR gamma-deficient mice showed overexpression and hypersecretion of leptin despite the smaller size of adipocytes and decreased fat mass, which may explain these phenotypes at least in part. This study reveals a hitherto unpredicted role for PPAR gamma in high-fat diet-induced obesity due to adipocyte hypertrophy and insulin resistance, which requires both alleles of PPAR gamma.  (+info)

Developmental toxicity studies in rats and rabbits with 3,5,6-trichloro-2-pyridinol, the major metabolite of chlorpyrifos. (8/189)

3,5,6-Trichloro-2-pyridinol (TCP), the primary metabolite of chlorpyrifos and chlorpyrifos-methyl, was evaluated for potential developmental toxicity. Groups of 32-34 bred female Fischer 344 rats were given 0, 50, 100, or 150 mg TCP/kg/day by gavage on gestation days 6-15; the fetuses were evaluated on gestation day 21. Similarly, groups of 16 inseminated female New Zealand White rabbits were given 0, 25, 100, or 250 mg TCP/kg/day by gavage on gestation days 7-19, and fetuses were evaluated on gestation day 28. No clinical signs of toxicity attributed to TCP were noted in either species. In rats, at 150 mg/kg/day, maternal effects included slight decreases in feed consumption, significantly depressed body weight gain (25% relative to controls) resulting in significantly lower maternal terminal body weights, and increased relative liver weight. At 100 mg/kg/day, maternal body weight gain in rats was depressed approximately 22%. Among rabbits, maternal effects were limited to the group given 250 mg/kg/day, which lost an average of approximately 70 g during the treatment period (vs. 140 g in the controls). There were no effects on fetal weight or viability, nor were there significant increases in any fetal alteration in either species. A slightly higher (not statistically significant) than usual incidence of central nervous system anomalies occurred in rabbits, but these anomalies were found in both treated and control groups in this study as well as contemporaneous studies of unrelated compounds. This, and the fact that these anomalies were not seen with the parent compound, chlorpyrifos, suggest that their origin was spontaneous. Thus, TCP was not considered fetotoxic or teratogenic in either rats or rabbits, even at dose levels that produced maternal toxicity.  (+info)

Fetal viability is the point in pregnancy at which a fetus is considered capable of surviving outside the uterus, given appropriate medical support. Although there is no precise gestational age that defines fetal viability, it is generally considered to occur between 24 and 28 weeks of gestation. At this stage, the fetus has developed sufficient lung maturity and body weight, and the risk of neonatal mortality and morbidity significantly decreases. However, the exact definition of fetal viability may vary depending on regional standards, medical facilities, and individual clinical assessments.

Pregnancy is a physiological state or condition where a fertilized egg (zygote) successfully implants and grows in the uterus of a woman, leading to the development of an embryo and finally a fetus. This process typically spans approximately 40 weeks, divided into three trimesters, and culminates in childbirth. Throughout this period, numerous hormonal and physical changes occur to support the growing offspring, including uterine enlargement, breast development, and various maternal adaptations to ensure the fetus's optimal growth and well-being.
