Inhibition of platelet derived growth factor (PDGF) can increase the efficacy of other cancer therapeutics, but the cellular mechanism is incompletely understood. We examined the cellular effects on tumor vasculature of a novel DNA oligonucleotide aptamer (AX102) that selectively binds PDGF-B. Treatment with AX102 led to progressive reduction of pericytes, identified by PDGF receptor beta, NG2,...
background: in this study, we examined a new two step induction protocol for improving the differentiation of human umbilical cord blood-derived mesenchymal stem cells into neural progenitor cells. materials and methods: human umbilical cord blood-derived mesenchymal stem cells were first cultured in dulbecco’s modified eagle medium supplemented with 10% fetal bovine serum in a humidified incub...
Inhibition of platelet-derived growth factor receptor (PDGFR) signaling restricts the growth of human breast cancer in the bone of nude mice. We hypothesized that osteoblast-secreted substances may alter the response capacity of breast cancer cells to the PDGFRs tyrosine kinase inhibitor imatinib mesylate. We found that osteoblast-conditioned medium (OCM) increases the proliferation rate of the...
background: it has been known that brain-derived neurotrophic factor (bdnf) is involved in neural survival and long term memory (ltm). here we hypothesized that bdnf as a potent neurotrophic factor might modulate amnestic effect induced by morphine. objectives: the aim of this study was to examine whether infusion of exogenous bdnf in the ca1 regions of the dorsal hippocampi could ameliorate me...
Objective: At present, growth factor-containing products such as enamel matrix derivatives, recombinant bone morphogenetic protein (rh-BMP), recombinant platelet derived growth factor and platelet rich plasma (PRP) have gained increasing attention. PRP is an autologous source of platelet growth factors used to enhance healing of soft and hard tissues. PRP has gained popularity due to its auto...
The FGF receptors (FGFR) are tyrosine kinases that are constitutively activated in a subset of tumors by genetic alterations such as gene amplifications, point mutations, or chromosomal translocations/rearrangements. Recently, small-molecule inhibitors that can inhibit the FGFR family as well as the VEGF receptor (VEGFR) or platelet-derived growth factor receptor (PDGFR) family displayed clinic...
OBJECTIVE Knockout studies have demonstrated crucial roles for the platelet-derived growth factor-B and its cognate receptor, platelet-derived growth factor receptor-beta (PDGFR-beta), in blood vessel maturation, that is, the coverage of newly formed vessels with mural cells/pericytes. This study describes the consequences of a constitutively activating mutation of the PDGFR-beta (Pdgfrb(D849V)...
