Epidermal mucous metaplasia of cultured 13-day-old chick embryonic tarsometatarsal skin can be induced by culture in medium containing retinol (20 microM) for only 8-24 h and then in a chemically defined medium without vitamins or serum for 6 days. In the induction of mucous metaplasia, retinol
Here we report on the use of a new real-time polymerase chain reaction (PCR) method to detect and quantify the activating gene mutation of the tyrosine kinase JAK2. We evaluated patients with myelofibrosis with myeloid metaplasia (MMM; n=25) for the gene mutation prior to allogeneic stem cell
Myelofibrosis with myeloid metaplasia (MMM) is an uncommon chronic myeloproliferative disorder characterized by clonal stem cell proliferation and reactive non-clonal proliferation of bone marrow fibroblasts with fibrosis. In the absence of curative therapy, the current management for the majority
Polycythemia vera (PV), essential thrombocythemia (ET), and myeloid metaplasia with myelofibrosis (MMM) are clonal disorders arising from hematopoietic progenitors. An internet-based protocol was used to collect clinical information and biological specimens from patients with these diseases.
Angiogenesis is part of the pathophysiology of myelofibrosis with myeloid metaplasia (MMM). PTK787/ZK 222584 (PTK/ZK) is a novel inhibitor of vascular endothelial growth factor receptors. Twenty-nine patients with MMM received a continuous dosing schedule of PTK/ZK doses of 500 or 750 mg twice daily
An association between an activating JAK2 mutation (JAK2(V617F)) and BCR/ABL-negative myeloproliferative disorders was recently reported in multiple simultaneous publications. In the current study, mutation analysis for JAK2(V617F) was performed in peripheral blood mononuclear cells (PBMC) from 157
We hypothesized that foreign bodies in airways cause inflammation leading to goblet cell metaplasia. Instilled agarose plugs lodged in the bronchi of pathogen-free rats caused a time-dependent increase in Alcian blue-periodic acid-Schiff staining that was detected within 24 h and markedly increased
Background: Cancer subtype switching, which involves unclear cancer cell origin, cell fate decision, and transdifferentiation of cells within a confined tumor microenvironment, remains a major problem in pancreatic cancer (PDA).
Cell-surface receptor tyrosine kinases play pivotal roles in development, tissue repair, and normal cellular homeostasis. Aberrant expression or signaling patterns of these kinases has also been linked to the progression of a diversity of diseases, including cancer, atherosclerosis, asthma, and
Idiopathic myelofibrosis is a chronic myeloproliferative disorder being featured by progressive accumulation of connective tissue in concert with marked neovascularization (angiogenesis) of the bone marrow. Both fibrogenesis and angiogenesis are considered to develop consequent to the intramedullary
BACKGROUND
Increased bone marrow angiogenesis and vascular endothelial growth factor (VEGF) levels are of adverse prognostic significance in patients with myeloproliferative disorders (MPD), including agnogenic myeloid metaplasia (AMM), chronic myeloid leukemia in blastic phase (CML-BP), and chronic
BACKGROUND
Nearly all Taiwanese H. pylori stains are cagA-genopositive and encode CagA protein. In this study, we evaluated whether different intensity of tyrosine phosphorylated-CagA (p-CagA) had an impact on the clinical diseases and histological outcomes in this area.
RESULTS
We enrolled 469
In our cloning strategy to identifytyrosine kinases implicated in the regulation of prostate growth, the dog fer cDNA was obtained and shown to be highly homologous to known fer cDNAs. Using a polyclonal Fer antibody directed against a C-terminal peptide, we studied its associations with cortactin,
BACKGROUND
The intestinal type of gastric cancer is thought to originate from cancer precursor lesions, progressing from H. pylori-induced chronic gastritis, atrophic gastritis, to intestinal metaplasia (IM) and dysplasia. Tyrosine kinases (tyr-k) represent the family of proteins that are widely
BACKGROUND
Spleen tyrosine kinase (Syk) is important for Fc and B-cell receptor-mediated signaling.
OBJECTIVE
To determine the activity of a specific Syk inhibitor (R406) on mast cell activation in vitro and on the development of allergen-induced airway hyperresponsiveness (AHR) and inflammation in
