Control of growth and differentiation by Drosophila RasGAP, a homolog of p120 Ras-GTPase-activating proteinP Feldmann
Cancer Research Campaign Center for Cell and Molecular Biology, The Institute of Cancer Research, Chester Beatty Laboratories, London SW3 6JB, United Kingdom
Mol Cell Biol 19:1928-37. 1999..Genetic interactions, however, suggested a Ras-independent role for RasGAP in the regulation of growth. The system described here should enable genetic screens to be performed to identify regulators and effectors of p120 Ras-GAP...
Signalling through phosphoinositide 3-kinases: the lipids take centre stageS J Leevers
Department of Biochemistry and Molecular Biology, University College London, Gower Street, London WC1E 6BT, UK
Curr Opin Cell Biol 11:219-25. 1999..Also in 1998, PTEN - a major tumour suppressor in human cancer - was also shown to antagonise PI3K signalling by removing the 3-phosphate from 3-phosphoinositides...
Growth control: invertebrate insulin surprises!S J Leevers
Ludwig Institute for Cancer Research, 91 Riding House Street, W1W 7BS, London, UK
Curr Biol 11:R209-12. 2001..Invertebrates have been found to possess more insulin-like ligands than predicted, some of which behave as receptor antagonists...
Perspectives: cell biology. All creatures great and smallS J Leevers
Ludwig Institute for Cancer Research, London, UK

Extension of life-span by loss of CHICO, a Drosophila insulin receptor substrate proteinD J Clancy
Department of Biology, University College London, Wolfson House, 4 Stephenson Way, London NW1 2HE, UK
Science 292:104-6. 2001..The dwarf phenotype of chico homozygotes was also unnecessary for extension of life-span. The role of insulin/IGF signaling in regulating animal aging is therefore evolutionarily conserved...
Regulation of imaginal disc cell size, cell number and organ size by Drosophila class I(A) phosphoinositide 3-kinase and its adaptorD Weinkove
Ludwig Institute for Cancer Research 91 Riding House Street, W1P 8BT, Department of Biochemistry and Molecular Biology Gower Street, London, UK
Curr Biol 9:1019-29. 1999..These observations have led us to investigate the role of Dp100 and its adaptor, p60, in the control of imaginal disc cell size, cell number and organ size...
Do growth and cell division rates determine cell size in multicellular organisms?C M Coelho
Ludwig Institute for Cancer Research, London W1P 8BT, UK
J Cell Sci 113:2927-34. 2000..These interactions may provide a means of coordinating growth and cell division, such that cells divide only when they are above a minimum size...
Phosphoinositide 3-kinases: a conserved family of signal transducersB Vanhaesebroeck
Ludwig Institute for Cancer Research, London, UK
Trends Biochem Sci 22:267-72. 1997..Potential signalling pathways downstream of PI3Ks have been elucidated and PI3K function is now being characterised in several model organisms...
p60 is an adaptor for the Drosophila phosphoinositide 3-kinase, Dp110D Weinkove
Ludwig Institute for Cancer Research, 91 Riding House Street, London W1P 8BT, United Kingdom
J Biol Chem 272:14606-10. 1997..The complex was found in larvae, pupae, and adults, consistent with p60 functioning as the adaptor for Dp110 throughout the Drosophila life cycle...
The Drosophila phosphoinositide 3-kinase Dp110 promotes cell growthS J Leevers
Ludwig Institute for Cancer Research, London, UK
EMBO J 15:6584-94. 1996..These data imply a role for Dp110 in growth control during Drosophila development and have implications for the function of class I PI3Ks in other organisms...

Alternative splicing of the Drosophila PTEN geneA Smith
Section of Gene Function and Regulation, Chester Beatty Laboratories, Institute of Cancer Research, 237 Fulham Road, London, UK
Biochim Biophys Acta 1447:313-7. 1999..Here we show that the PTEN gene is conserved in the invertebrate Drosophila melanogaster and demonstrate that the gene undergoes alternative splicing...
Synthesis and function of 3-phosphorylated inositol lipidsB Vanhaesebroeck
Ludwig Institute for Cancer Research, Riding House Street, London W1W 7BS
Annu Rev Biochem 70:535-602. 2001..This field is now moving toward a genetic dissection of 3-phosphoinositide action in a variety of model organisms. Such approaches will reveal the true role of the 3-phosphoinositides at the organismal level in health and disease...

Int J Cancer 45:342-6. 1990..All 6 cell lines expressed c-fgr mRNA at elevated levels compared to EBV-negative BL cell lines...
Structure of the complete human c-fgr proto-oncogene and identification of multiple transcriptional start sitesM Patel
Department of Biochemistry, University College of Middlesex School of Medicine, London, UK
Oncogene 5:201-6. 1990..We have also mapped multiple transcriptional start sites within the 5' flanking region of the c-fgr gene and present an analysis of the nucleotide sequences within this region which may be responsible for regulating c-fgr expression...
The genetic control of organ growth: insights from DrosophilaD Weinkove
Department of Molecular Biology, The Netherlands Cancer Institute, Amsterdam, 1066 CX, The Netherlands
