expression of receptor tyrosine kinase ror1 in a wide variety of cancers has emerged as a new era focusing on targeting this receptor in cancer therapy. our preliminary re-sults indicate the presence of a truncated transcript of ror1 in tumor cells. the trun-cated ror1 encompasses extracellular and transmembrane domains, lacking catalytic kinase domain (ror1-ecd). as enzyme activity is highly d...
Receptor-associated prorenin system (RAPS) refers to the pathogenic mechanism whereby prorenin binding to (pro)renin receptor [(P)RR] dually activates tissue renin-angiotensin system (RAS) and RAS-independent signaling via (P)RR. The aim of this study is to determine the association of RAPS with idiopathic epiretinal membrane (iERM). Reverse transcription-PCR indicated the expression of RAPS co...
Glial cell line-derived neurotrophic factor (GDNF) is released by glioma cells and promotes tumor growth. We have previously found that GDNF from the a chemoattractant for microglial cells, immune of central nervous system. Here we show increases matrix metalloproteinase (MMP) 9 MMP14 expression in cultured mixed sexes neonatal mice. The GDNF-induced MMP9 upregulation mediated family receptor a...
AP-1 is an ubiquitous transcription factor which is composed of the Jun and Fos proto-oncogene proteins and is thought to play a role in both cell proliferation and differentiation. We have used an immortal, bipotential oligodendrocyte-type-2 astrocyte progenitor cell line (O-2A/c-myc) which can differentiate into oligodendrocytes or type-2 astrocytes in vitro, to investigate whether AP-1 DNA-b...
PURPOSE To study target-specific delivery of doxorubicin (Dox) using an RNA aptamer against epithelial cell adhesion molecule (EpCAM) in retinoblastoma (RB) cells. METHODS The binding affinity of the EpCAM aptamer to RB primary tumor cells, Y79 and WERI-Rb1 cells, and Müller glial cell lines were evaluated with flow cytometry. Formation of physical conjugates of aptamer and Dox was monitored ...
background and objective: gliomas are the most common primary brain tumors. despite therapeutic advances, the majority of gliomas do not respond to either chemo or radiotherapy. cd117, the gene product of c-kit has been expressed in cells of glial tumors. because gastrointestinal stromal tumors (gists) that express cd117 respond dramatically to treatment with tyrosine kinase inhibitors, identif...
Objective(s): Glial cell line-derived neurotrophic factor (GDNF) can effectively promote axonal regeneration,limit axonal retraction,and produce a statistically significant improvement in motor recovery after spinal cord injury (SCI). However, the role in primate animals with SCI is not fully cognized. Materials and Methods:18 healthy juvenile rhesuses were divided randomly into six groups, obs...
Background: Research suggests the inhibitory effects of deferoxamine as an iron chelator on erythroleukemia cells. The present study was conducted to investigate the effects of deferoxamine on B92 cells as a model of glial cells carcinoma. Materials and Methods: The present experimental study treated 6×104 B92 cells with 0, 10, 50 and 100 µM of deferoxamine for 24 hours in the presence or absen...
objective(s):theneuroprotective effect of lithium has been attributed to its therapeutic action. however, the role of glial cells particularly astrocytes, and the possible interactions between neurons and astrocytes in neuroprotective effects of lithium have been disregarded. thus, the aim of this study was to evaluate the direct effects of lithium on brain derived neurotrophic factor (bdnf) an...
