Cell movements during gastrulation: snail dependent and independent pathwaysY Tony Ip
Program in Molecular Medicine and Department of Cell Biology University of Massachusetts Medical School, Worcester, Massachusetts 01605, USA
Curr Opin Genet Dev 12:423-9. 2002..Together with other regulatory molecules including Wnt and BMP, the Snail pathways specify cell fate and reorganize cellular machineries to coordinate morphological changes and cell movements during gastrulation...
Toll and Toll-9 in Drosophila innate immune responseRaul Bettencourt
Program in Molecular Medicine, University of Massachusetts Medical School, Worcester, Massachusetts 01605, USA
J Endotoxin Res 10:261-8. 2004..Thus, the innate immune response in Drosophila is regulated by complex mechanisms, which involve Toll and other Toll-related proteins...
Hemolymph-dependent and -independent responses in Drosophila immune tissueRaul Bettencourt
Program in Molecular Medicine, University of Massachusetts Medical School, Worcester, Massachusetts 01605, USA
J Cell Biochem 92:849-63. 2004..We further show that Dorsal mutant larvae have much lower phenoloxidase activity, consistent with a more important role of Dorsal in innate immunity than previously shown...
Helicase89B is a Mot1p/BTAF1 homologue that mediates an antimicrobial response in DrosophilaYoshimasa Yagi
Program in Molecular Medicine, University of Massachusetts Medical School, 373 Plantation Street, Worcester, Massachusetts 01605, USA
EMBO Rep 6:1088-94. 2005..Thus, Helicase89B positively regulates gene expression during innate immune response and may act as a link between NF-kappaB-related transcription factors and the basal transcription machinery...
The repressor function of snail is required for Drosophila gastrulation and is not replaceable by Escargot or WorniuKirugaval Hemavathy
Program in Molecular Medicine, University of Massachusetts Medical School, Worcester, MA 01605, USA
Dev Biol 269:411-20. 2004..Together, the results show that the repressor function of Snail is essential for gastrulation. The repression of target genes by Snail may permit other factors in the ventral cells to positively promote mesoderm invagination...
Worniu, a Snail family zinc-finger protein, is required for brain development in DrosophilaShovon I Ashraf
Program in Molecular Medicine, University of Massachusetts Medical School, Worcester, Massachusetts 01605, USA
Dev Dyn 231:379-86. 2004..The results suggest that the loss of Worniu function within the neuroblasts ultimately causes the larval brainstem to fail to go through shortening during development...
Msk is required for nuclear import of TGF-{beta}/BMP-activated SmadsLan Xu
Program in Molecular Medicine, University of Massachusetts Medical School, Worcester, MA 01605, USA
J Cell Biol 178:981-94. 2007..We have thus identified new evolutionarily conserved proteins that are important in the signal transduction of TGF-beta and BMP into the nucleus...
Heterodimers of NF-kappaB transcription factors DIF and Relish regulate antimicrobial peptide genes in DrosophilaTakahiro Tanji
Department of Cell Biology, University of Massachusetts Medical School, Worcester, MA 01605, USA
Proc Natl Acad Sci U S A 107:14715-20. 2010..The DIF and Relish complex is detectable in whole animal extracts, suggesting that this heterodimer may function in vivo to increase the spectrum and level of antimicrobial peptide production in response to different infections...
Multimerization and interaction of Toll and Spätzle in DrosophilaXiaodi Hu
Program in Molecular Medicin, University of Massachusetts Medical School, 373 Plantation Street, Worcester, MA 01605, USA
Proc Natl Acad Sci U S A 101:9369-74. 2004..Together, our results suggest that multimerization may be a regulated, essential step for Toll-receptor activation...
Identification of phosphatases for Smad in the BMP/DPP pathwayHong B Chen
Program in Molecular Medicine, University of Massachusetts Medical School, Worcester, Massachusetts 01605, USA
Genes Dev 20:648-53. 2006..We show that the mammalian PDPs are important in dephosphorylation of BMP-activated Smad1 but not TGF-beta-activated Smad2 or Smad3. Thus, PDPs specifically inactivate Smads in the BMP/DPP pathway...
Drosophila WntD is a target and an inhibitor of the Dorsal/Twist/Snail network in the gastrulating embryoAtish Ganguly
Program in Molecular Medicine, University of Massachusetts Medical School, Worcester, MA 01605, USA
Development 132:3419-29. 2005..Thus, these results together demonstrate that WntD is regulated by the Dorsal/Twist/Snail network, and is an inhibitor of Dorsal nuclear localization and function...
Regulators of the Toll and Imd pathways in the Drosophila innate immune responseTakahiro Tanji
Program in Molecular Medicine, University of Massachusetts Medical School, 373 Plantation Street, Worcester, MA 01605, USA
Trends Immunol 26:193-8. 2005..In this Review, we will discuss the recent genetic, genomic and RNA interference analyses that have unveiled additional intricacy in the Toll and Imd pathways...
Learning the codes of fly immunityRaul Bettencourt
Program in Molecular Medicine, University of Massachusetts Medical School, 373 Plantation Street, Worcester, MA 01605, USA
Mol Cell 13:1-2. 2004..In this issue of Molecular Cell, Senger and colleagues demonstrate that a large number of immunity genes in Drosophila fat bodies can be regulated by a simple code, REL-GATA...
The Drosophila Toll-9 activates a constitutive antimicrobial defenseJames Y Ooi
Program in Molecular Medicine and Department of Cell Biology, University of Massachusetts Medical School, Worcester, MA 01605, USA

Program in Molecular Medicine, University of Massachusetts Medical School, Worcester, MA 01605, USA
Cell Stem Cell 4:49-61. 2009..By using this newly established system of intestinal stem cell proliferation and tissue regeneration, we find that the insulin receptor signaling pathway is required for intestinal stem cell division...
Pathogenic stimulation of intestinal stem cell response in DrosophilaMadhurima Chatterjee
Program in Molecular Medicine, University of Massachusetts Medical School, Worcester, Massachusetts 01605, USA
J Cell Physiol 220:664-71. 2009..This system should allow molecular and genetic analyses of stem cell-mediated tissue repair...

Program in Molecular Medicine, University of Massachusetts Medical School, Worcester, MA 01605, USA
Mol Cell Biol 27:4578-88. 2007..These results illustrate how specific ligand binding by separate upstream pattern recognition receptors can be translated into a broad-spectrum host response, a hallmark of innate immunity...

Department of Molecular Biology and Pharmacology, Washington University School of Medicine, 660 S Euclid Avenue, Campus Box 8103, Saint Louis, Missouri 63110, USA
EMBO Rep 5:1058-63. 2004..These phenotypes only partially overlap those caused by mutations in D-MEKK1 and dTAK1, suggesting that the D-p38a gene is required to mediate some, but not all, of the functions ascribed to p38 signalling...
