    ..Since tumor-aggravating properties have been found in mice overexpressing PLD2 enzyme, the 3D model of PLD2 will be also useful, to a large extent, in developing pharmaceuticals to modulate its in vivo activity. ..

    ..Thus, PLD2-mediated production of PA contributed to the control of EGFR exposure to ligand through a multipronged transcriptional and posttranscriptional program during the out-of-control accumulation of EGFR signaling in cancer cells. ..
  7. Gomez Cambronero J. The exquisite regulation of PLD2 by a wealth of interacting proteins: S6K, Grb2, Sos, WASp and Rac2 (and a surprise discovery: PLD2 is a GEF). Cell Signal. 2011;23:1885-95 pubmed publisher
    ..This provides only the latest level of PLD2 regulation in a field that promises newer and exciting advances in the next few years. ..

    ..It can further prevent inhibition of apoptosis and allow cells to survive nutrient deprivation, which normal cells cannot do. ..
  9. Ganesan R, Mallets E, Gomez Cambronero J. The transcription factors Slug (SNAI2) and Snail (SNAI1) regulate phospholipase D (PLD) promoter in opposite ways towards cancer cell invasion. Mol Oncol. 2016;10:663-76 pubmed publisher
    ..The newly uncovered feedback loops in highly invasive cancer cells have important implications in the process of EMT. ..
