Role of the PI-3K/Akt and ERK pathways in phencyclidine-induced neurotoxicity in neonatal rats and the protection by lithium and BDNF
… of PCP on the phosphatidylinositol-3 kinase (PI-3K)/Akt and extracellular regulated kinase (ERK) pathways and suppressed activation of the pro-apoptotic factor, glycogen synthase kinase-3â (GSK-3â), evoked by PCP. Furthermore, blocking either the PI-3K/Akt or the ERK pathway …

Molecular Mechanism of Tetraspanin CD9 Mediated Cell Motility
… show that the phosphatidylinositol-3 kinase (PI-3K) inhibitors, wortamannin and LY294002 inhibited CD9 promoted cell motility in Chinese hamster ovary (CHO) cells. In contrast, inhibitors targeting protein kinase C or mitogen-activated protein kinase had no effect on CD9 driven CHO cell …

Identification of a ciliary defect associated with pulmonary nontuberculous mycobacterial disease
… but no consistent immunological abnormalities despite extensive investigation. I hypothesized that respiratory epithelial dysfunction might play a critical role in PNTM disease predisposition because diseases with defects of mucociliary transport have high rates of PNTM disease that increase with …

Σηματοδοτικοί μηχανισμοί κατά την απόπτωση και την κυτταροφαγία στα αιμοκύτταρα της μύγας της Μεσογείου
… και φωσφορυλίωση των κινασών FAK, Src, ERK, PI-3K και Akt εξαρτάται από τo στάδιο ανάπτυξης, ενώ το μέγιστο της έκφρασης και φωσφορυλίωσής τους παρατηρείται στο στάδιο της λευκής νύμφης, όπου σημειώνεται και το μέγιστο της απόπτωσης. Η απόπτωση φαίνεται να επηρεάζεται από τα σηματοδοτικά …

Mechanisms of Ipsapirone-Mediated Neuroprotection of Ethanol-Treated Fetal Rhombencephalic Neurons: Role of Endogenous Antioxidants
… to ethanol can cause serious damage to the developing central nervous system. Both in vivo and in vitro studies demonstrate the vulnerability of the developing serotonergic system to the damaging effects of ethanol. However, treatment with a serotonin-1A (5-HT1A) agonist prevents the …

Regulation of Exercise-Dependent Cardiac Growth by MicroRNAs
… miR-499 are mediated through regulation of IGF-1/PI-3K/Akt and beta-catenin signaling pathways, which drive physiological growth of the heart. I demonstrated the effects of miR-499 on physiological cardiac growth are mediated, at least in part, through repression of a network of genes including …

Steroid signalling in the human ovarian surface epithelium wound healing
The human ovarian surface epithelium (hOSE) is a cell monolayer that covers the surface of the ovary. Natural events like incessant ovulation, associated reproductive hormone action prior to and post-ovulation, along with the ovulationassociated inflammation, that result in injury and repair of …

The Regulation of Phosphorylation Events in Platelets
… studies have shown MLC phosphorylation occurs rapidly and is essential for shape change following the stimulation of ADP receptors. Technological advances in antibody development have resulted in the generation of commercially available phospho-specific antibodies for MLC phosphorylated on either …

THE ABSENCE OF C3AR AND C5AR SIGNAL TRANSDUCTION PROMOTES T REGULATORY CELL DIFFERENTIATION AND REGULATES IMMUNOLOGIC TOLERANCE
… signals are not transduced into CD4+ T cells, PI-3K¿-AKT-mTOR signaling ceases, PKA activation increases, auto-inductive TGF-ß1 signaling initiates, and CD4+ T cells become Foxp3+ T regulatory cells (iTregs). Endogenous TGF-ß1 suppresses C3aR and C5aR signaling by preventing C3a and C5a …

ROLE OF ENDOTHELIN-1 IN THE REGULATION OF THE SWELLING-ACTIVATED Cl- CURRENT IN ATRIAL MYOCYTES
… by the highly selective ICl,swell inhibitor DCPIB and by osmotic shrinkage. Selective ETA blockade (BQ123), but not ETB blockade (BQ788), fully suppressed the ET-1-induced current. ET-1-induced ICl,swell was abolished by blockade of EGFR kinase (AG1478) and PI-3K inhibitors (LY294002 and …

Regulation Of Membrane-Type 1 Matrix Metalloproteinase In Prostate Cancer
… and in PC3-N cells using chromatin immunoprecipitation analysis and silencing RNA. Investigation of signaling pathways in these cells showed that DU-145 cells express constitutively phosphorylated extracellular stress-regulated kinase (ERK), whereas PC-3 and PC-3N cells express constitutively …

MiR-145 is a tumor suppressor in both tumor progression and metastasis
… regulated through the phosphoinositide-3 kinase (PI-3K)/Akt and p53 pathways. Importantly, p53 transcriptionally induces the expression of miR-145 by interacting with a potential p53 response element (p53RE) in the miR-145 promoter. We further show that c-Myc is a direct target for miR-145. …

IGF2R: A NEW PLAYER IN THE INSULIN LIKE GROWTHFACTOR 2 (IGF2) PATHWAY SUSTAINING ADRENOCORTICAL TUMOURS CELL GROWTH
… S1P, as responsible for the activation of PI-3K/Akt and MAPK pathways. Indeed, we confirmed the overexpression of SphK, mainly the isoform SphK1, in ACT compared to NA. Moreover, this was the first project to correlate IGF2R with SphK in ACT, proving that in case of IGF2R knockdown or …
