Association between AKT1 gene and Parkinson's disease: A protective haplotype
(2008)Variation in AKT1 has been associated with schizophrenia, bipolar disease and type 11 diabetes. The aim of the present study was to investigate the potential role of variability within AKT1 as a risk factor for Parkinson's ... -
Cobalt induces hypoxia-inducible factor-1 alpha expression in airway smooth muscle cells by a reactive oxygen species- and PI3K-dependent mechanism
(2004)Cobalt can mimic hypoxia and has been implicated as a cause of lung defects. However, the effect of cobalt on airway smooth muscle (ASM) cells has not been analyzed in detail. In this article, we use primary cultures of ... -
Exposure of differentiated airway smooth muscle cells to serum stimulates both induction of hypoxia-inducible factor-1 alpha and airway responsiveness to ACh
(2007)Airway smooth muscle (ASM) cells are characterized by phenotypic plasticity and can switch between differentiated and proliferative phenotypes. In rabbit tracheal ASM cells that had been differentiated in vitro by serum ... -
hTERT regulation by NF-kappa B and c-myc in irradiated HER2-positive breast cancer cells
(2011)Purpose: Telomerase activity (TA), frequently observed in cancer, compensates for telomere shortening thus preventing cell senescence and conferring resistance to therapy. In the present study, we investigated the expression ... -
Post-operative combined radiation and chemotherapy with temozolomide and irinotecan in patients with high-grade astrocytic tumors. A phase II study with biomarker evaluation
(2006)Background: Clinical studies have shown that temozolomide (TMZ) and irinotecan demonstrate activity in high grade astrocytic tumors (HGAT). However, the optimal schedule of administration is unknown. Patients and Methods: ... -
Role of ethylene in the protection of tomato plants against soil-borne fungal pathogens conferred by an endophytic Fusarium solani strain
(2007)An endophytic fungal isolate (Fs-K), identified as a Fusarium solani strain, was obtained from root tissues of tomato plants grown on a compost which suppressed soil and foliar pathogens. Strain Fs-K was able to colonize ... -
Role of lupeol synthase in Lotus japonicus nodule formation
(2011)P>Triterpenes are plant secondary metabolites, derived from the cyclization of 2,3-oxidosqualene by oxidosqualene cyclases (OSCs). Here, we investigated the role of lupeol synthase, encoded by OSC3, and its product, lupeol, ... -
The role of ubiquitin-proteasome system in glioma survival and growth
(2013)High-grade gliomas represent a group of aggressive brain tumors with poor prognosis due to an inherent capacity of persistent cell growth and survival. The ubiquitin-proteasome system (UPS) is an intracellular machinery ... -
Study of the interaction among Notch pathway receptors, correlation with stemness, as well as their interaction with CD44, dipeptidyl peptidase-IV, hepatocyte growth factor receptor and the SETMAR transferase, in colon cancer stem cells
(2013)Context: The Notch signaling pathway is one of the most important pathways during normal development and implicated in self-renewal of adult stem cells and differentiation of progenitor cells. Abnormal expression of Notch ...
