PURPOSE The mitogenic action of PDGF has been shown to associate with reactive oxygen species (ROS) generation, but the mechanism leading to ROS production and subsequent cell proliferation is not clear. We investigated the upstream membrane-bound target proteins involved in PDGF-stimulated signal transduction in human lens epithelial cell (HLE B3), using specific inhibitors and transfected cel...
We report here the 4.29-Mb draft genome sequence of Myroides sp. N17-2, a new bacterium isolated from radiation-polluted soils in Xinjiang, Uyghur Autonomous Region, China. The acquisition of its genome will provide valuable information to reveal the relationship between radiation and multidrug resistance.
BACKGROUND Despite the magnitude of dizziness/vertigo in primary health care, prospective studies are scarce, and few studies have focused on vocational consequences. Using the International Classification of Primary Health Care (ICPC), GPs have two alternative diagnoses, H82 (vertiginous syndrome) and N17 (vertigo/dizziness), when issuing sickness certificates to these patients. AIM To asses...
This study investigated the effect of eye gaze and head position on vestibular-evoked potentials (VsEPs). Head position would be expected to affect myogenic sources, and eye position is known to affect ocular myogenic responses (ocular vestibular-evoked myogenic potentials), whereas a neurogenic source should behave otherwise. Eleven healthy subjects were recruited, and VsEPs, using 72-channel ...
Metformin has been shown to inhibit tumor growth in xenograft rodent models of adult cancers, and various human clinical trials are in progress. However, the precise molecular mechanisms of metformin action are largely unknown. In the present study we examined the anti-tumor activity of metformin against neuroblastoma, and determined the underlying signaling mechanisms. Using human neuroblastom...
Time-lapse video-microscopy unambiguously shows that fibroblast filopodia are the scaffold of lamellipodia nucleation that allows anisotropic cell spreading. This process was dissected into elementary stages by monitoring cell adhesion on micropatterned extracellular matrix arrays of various pitches. Adhesion structures are stabilized by contact with the adhesive plots and subsequently converte...
Here we show a requirement for the Cdc42 and Rac1 GTPases in endothelial cell (EC) morphogenesis in three-dimensional extracellular matrices. Cdc42 and Rac1 specifically regulate EC intracellular vacuole and lumen formation in both collagen and fibrin matrices. Clostridium difficile toxin B (which blocks all three Rho GTPases) completely inhibited the ability of ECs to form both vacuoles and lu...
Penelitian ini bertujuan untuk menyeleksi dan mendapatkan isolat jamur endofit dari tanaman nipah (Nypa fruticans) yang berdaya antagonis tinggi terhadap G. boninense penyebab penyakit busuk pangkal batang (BPB) pada kelapa sawit secara in vitro serta mengidentifikasinya hingga tingkat genus. dilakukan di Laboratorium Penyakit Tanaman Fakultas Pertanian Universitas Riau dimulai November 2020 Fe...
Glucagon like peptide-1 (GLP1) is a Gs-coupled receptor agonist that exerts multiple effects on pancreatic -cells, including the stimulation of insulin gene expression and secretion. In this report, we show that treatment of the mouse pancreatic -cell line MIN6 with GLP1 leads to the glucose-dependent activation of Erk. These effects are mimicked by forskolin, a direct activator of adenylate cy...
Cell-cell contacts play important roles in the homeostasis of normal epithelium and in the steps of metastasis of tumor cells, although signaling mechanisms to regulate cell-cell contacts are unclear. In this study, we observed that phenotype of no cell-cell contacts in rat intestinal epithelial cell subline (RIE1-Sca) correlated with increased Erk1/2 signaling activity, compared to that of par...
