Background: Times New Roman 9, single space, contains the brief description of research. Stroke is greatest cause disability and mortality worldwide. Several biological mechanisms underlying this disease such as failure glutamate reuptake ATP synthesis, resulting in high levels reactive oxygen species (ROS), neuroinflammatory responses, apoptosis, resulted cell death brain tissue damage. Neurot...

TrkC mediates many aspects of growth and development in the central nervous system. TrkC is expressed in a variety of non-neuronal tissues as well as human cancers. TrkC overexpression may drive tumorigenesis, invasion, and metastatic capability in cancer cells. However, relatively little is known about whether TrkC activity is also essential to maintain the malignant properties in human tumors...

Neurotrophin-activated receptor tyrosine kinases (Trks) regulate sensory neuron survival, differentiation, and function. To permanently mark cells that ever express TrkC-kinase, mice with lacZ and GFP reporters of Cre recombinase activity were crossed with mice having IRES-cre inserted into the kinase-containing exon of the TrkC gene. Prenatal reporter expression matched published locations of ...

This contribution features a small molecule that binds TrkC (tropomyosin receptor kinase C) receptor that tends to be overexpressed in metastatic breast cancer cells but not in other breast cancer cells. A sensitizer for (1)O2 production conjugated to this structure gives 1-PDT for photodynamic therapy. Isomeric 2-PDT does not bind TrkC and was used as a control throughout; similarly, TrkC- can...

The current work reveals that TrkC receptor is crucial to many aspects of tumorigenicity and metastasis of cancer. However, with only a few exceptions, such as colorectal cancer (CRC), where suppressing tumorigenic and metastatic ability via expression of TrkC as tumor suppressor have been proposed. These diverse lines of evidence led us to investigate whether TrkC is involved in CRC progressio...

TrkC, a member of the tropomyosin-related kinase (Trk) family of neurotrophin receptors, is implicated in the growth and survival of human cancer tissues. TrkC is also a potent oncoprotein expressed in tumors derived from multiple cell lineages, and functions as an active protein tyrosine kinase by neurotrophin-3 (NT-3). We previously reported that TrkC plays an essential role in tumor growth a...

We have constructed a recombinant adenovirus expression vector carrying the human neurotrophin-3 (NT-3) receptor TrkC (tyrosine protein kinase C) gene (rAd-TrkC; 2478 bp) and confirmed the expression of the encoded TrkC in green fluorescent protein (GFP)-murine neural stem cells (NSCs) by reverse transcription polymerase chain reaction (RT-PCR), Western blot analysis, and immunocytochemistry. T...

Neurotrophin receptor tyrosine kinases (Trks) have well-defined trophic roles in nervous system development through kinase activation by neurotrophins. Yet Trks have typical cell-adhesion domains and express noncatalytic isoforms, suggesting additional functions. Here we discovered noncatalytic TrkC in an unbiased hippocampal neuron-fibroblast coculture screen for proteins that trigger differen...

Signaling by brain-derived neurotrophic factor (BDNF) via the TrkB receptor, or by neurotrophin-3 (NT3) through the TrkC receptor support distinct populations of sensory neurons. The intracellular signaling pathways activated by Trk (tyrosine kinase) receptors, which in vivo promote neuronal survival and target innervation, are not well understood. Using mice with TrkB or TrkC receptors lacking...

Metastatic breast cancers are aggressive tumors associated with high levels of epithelial-mesenchymal transition (EMT) markers, activation of IL6/JAK2/STAT3 and PI3K/AKT pathways for cell growth, mobility, invasion, metastasis, and CSC status. We identified a new molecular and functional network present in metastasis that regulates and coordinates with TrkC. Inhibition of SOCS3-mediated JAK2 de...
