Disease relevance of PIK3CD

 

Psychiatry related information on PIK3CD

 

High impact information on PIK3CD

  • A PI3K has already been purified, cloned, and shown to be regulated by receptors that act via tyrosine kinase-dependent regulatory mechanisms [9].
  • Phosphoinositide 3 kinase (PI3K) is a key signaling enzyme implicated in receptor-stimulated mitogenesis, oxidative bursting in neutrophils, membrane ruffling, and glucose uptake [9].
  • We report that an immunologically, pharmacologically, and chromatographically distinct form of PI3K activity present in neutrophils and U937 cells is specifically activated by G protein beta gamma subunits [9].
  • The phosphoinositide 3-kinase (PI3K) family of enzymes is recruited upon growth factor receptor activation and produces 3' phosphoinositide lipids [10].
  • The lipid products of PI3K act as second messengers by binding to and activating diverse cellular target proteins [10].
 

Chemical compound and disease context of PIK3CD

 

Biological context of PIK3CD

  • However, p110delta that is recruited to activated receptors (such as CD28 in T cells) shows a time-dependent increase in Ser1039 phosphorylation and a concomitant decrease in associated lipid kinase activity [16].
  • Tracking analysis of IC87114-treated neutrophils indicated that PI3K delta activity was required for the directional component of chemotaxis, but not for random movement [17].
  • PTEN phosphatase, a product of PTEN tumor suppressor gene, exists in cells in phosphorylated and unphosphorylated form and has a central role in regulation of PI3K/Akt signalling which is involved in non-genomic action of estradiol [18].
  • Recent evidence indicates that phosphatidylinositol 3-kinase (PI3K) is a central regulator of mitosis, apoptosis and oncogenesis [19].
  • Thus, we delineate a novel SRF-dependent mitogenic cascade that is critical for PI3K- and growth factor-mediated cell cycle progression [19].
 

Anatomical context of PIK3CD

  • Inhibition of PI3K delta, however, did not block F-actin synthesis or neutrophil adhesion [17].
  • The results demonstrate that T. cruzi, through its TS, triggers the survival of host Schwann cells via the PI3K/Akt pathway, suggesting a role for PI3K/Akt in the pathogenesis of Chagas' disease [20].
  • Surprisingly, genetic deletion of the p110delta and p110gamma catalytic subunits resulted in a dramatic reduction in thymus size, cellularity, and lack of corticomedullary differentiation [21].
  • Our data demonstrate a role for p110delta signaling in B cell Ag presentation function, implicating 3-phosphoinositides and their targets in the latter stages of this process [22].
  • We show that treatment of macrophages with ATP results in production of reactive oxygen species (ROS), which stimulate the phosphatidylinositol 3-kinase (PI3K) pathway and subsequent Akt and ERK1/2 activation [23].
 

Associations of PIK3CD with chemical compounds

 

Regulatory relationships of PIK3CD

  • In contrast, inactivation of p110delta significantly impaired the ability of B cells to activate T cells in a BCR-mediated Ag uptake and presentation model [22].
 

Other interactions of PIK3CD

  • PI3Ks are critical signaling enzymes controlling many cellular processes, with the p110delta isoform playing a critical role in BCR signaling [22].
 

Analytical, diagnostic and therapeutic context of PIK3CD

  • Consistent with previous data, antibodies against p110delta and p110beta blocked FcepsilonR1-mediated degranulation in response to FcepsilonRI ligation [25].
  • Recently, it has been shown that Sonic Hedgehog-induced formation of medulloblastoma in an animal model is significantly enhanced by activation of the phosphatidylinositol 3'-kinase (PI3K) signaling pathway [26].
  • As assessed by Western blotting, protein levels of the serum-, and glucocorticoid-induced kinase (Sgk1) were directly and proportionally related to the current induced by either or both IGF-1 and aldosterone, effects also blocked by the PI3-K inhibitor LY294002 [27].
  • The purification yields were high using the optimized ratio of p85/p110 vector and small culture volumes, with 24mg/L cell culture media for p85alpha/p110alpha, 17.5mg/L for p85alpha/p110delta, and 3.5mg/L for p85alpha/p110beta [28].
  • This class of PI 3-kinase was identified exclusively by PCR and homology cloning approaches and not on the basis of cellular function [29].
