Oesophageal and oesophagogastric junction cancers represent a significant burden to public health. Clinical practice guidelines recommend treatment based on cellular molecular targets from tissue obtained before initiating therapy, including human epidermal growth factor receptor, microsatellite instability, mismatch repair, programmed death-ligand 1 neurotrophic receptor tyrosine kinase gene f...

background : fms-like tyrosine kinase 3 is a tyrosine kinase receptor that plays an important role in proliferation and differentiation of hematopoietic stem cells. internal tandem duplication and tyrosine kinase domain mutation are the two most common types of fms-like tyrosine kinase 3 mutations frequently reported in acute myeloid leukemia associated with pathogenesis of this disease. the pr...


 CADTH recommends that Rozlytrek be reimbursed by public drug plans for the treatment of adults with unresectable locally advanced or metastatic extracranial solid tumours, including brain metastases, have a neurotrophic tyrosine receptor kinase (NTRK) gene fusion without known acquired resistance mutation if certain conditions are met.
 should only to treat patients who previously f...

BACKGROUND Cigarette smoke exposure during prenatal and early postnatal periods increases the incidence of a variety of abnormal behaviors later in life. The purpose of this study was to identify the possible critical period of susceptibility to cigarette smoke exposure and evaluate the possibe effects of cigarette smoke during early life on brain-derived neurotrophic factor/neurotrophic tyrosi...

Congenital insensitivity to pain or more scientifically Hereditary sensory and autonomic neuropathies (HSAN) is a rare genetic disorder which associates dysfunction with varying degree of dysfunction. Due the peripheral neuropathy, decreased sensitivity even complete anesthesia may be present resulting in, on ophthalmological level, neurotrophic ulcers. We report case 2 sisters (JM KM) presenti...

Glial cell line–derived neurotrophic factor (GDNF) family ligand (GFL) consists of GDNF, neurturin (NRTN), artemin (ARTN), and persephin (PSPN). These GFLs signal through a receptor complex consisting coreceptor (GFRα1–4) as binding component, which has no intracellular domain is anchored to the plasma membrane with glycosylphosphatidylinositol, transmembrane RET (rearranged during transfection...

Drugs of abuse regulate the expression of several genes involved in receptor regulation and signalling, transcription factors and cytoskeleton proteins. Due to its implication in long-term memory consolidation, rat hippocampus was selected to identify genes that are differently regulated by morphine and/or cocaine administration. The animals were randomly separated into four groups given saline...

The tyrosine kinase receptor trkB is thought to mediate the biological actions of brain-derived neurotrophic factor. This receptor is expressed by a large variety of neurons during development. Truncated trkB molecules lacking the tyrosine kinase domain have also been described, but their functions remain elusive. In order to gain insight into their role, we studied the pattern of expression an...

A novel series of N-(3-(6-substituted-aminopyridin-3-yloxy)phenyl)-2-oxo-3-phenylimidazolidine-1-carboxamides targeting TrkA receptor tyrosine kinase was identified. SAR study of the series allowed us to design and synthesize compounds possessing inhibitory activity of TrkA kinase enzyme in the low nanomolar range with low residual activity against c-Met and with no significant activity against...
