An angiogenic role for the neurokines midkine and pleiotrophin in tumorigenesis.

چکیده
Recent analysis of bladder tumors has correlated expression of the neurokine midkine (MK) with poor patient survival. To examine a role for MK and the related pleiotrophin (PTN) in tumorigenesis, they were overexpressed in MCF-7 breast carcinoma cells. Expression had no effect on in vitro growth but conferred a growth advantage in vivo. Enhanced tumor growth correlated with increased vascular density and endothelial proliferation, implicating an angiogenic role for MK and PTN. Angiogenic activity of MK and PTN was confirmed in the rabbit corneal assay. Our data therefore identify two novel targets for antiangiogenic drug development.

متن کاملElevated plasma midkine and pleiotrophin levels in patients with systemic lupus erythematosus
Emerging evidence suggests that two heparin-binding growth factor, midkine and pleiotrophin are implicated in the pathogenesis of autoimmune diseases including SLE. To investigate the plasma midkine and pleiotrophin levels in SLE patients, as well as their correlation with major clinical parameters and interleukin-17 (IL-17) level in SLE, 83 SLE patients and 123 controls including 20 rheumatoid...
متن کاملIdentification of novel heparin-releasable proteins, as well as the cytokines midkine and pleiotrophin, in human postheparin plasma.
The heparin-releasable proteins are a group of proteins that are targeted to the endothelial surface by attachment to glycosaminoglycans and may have functions specific to the endothelium-blood interface. In this study, heparin-affinity chromatography of human postheparin plasma was used as a method to identify and study novel heparin-releasable proteins. Six proteins seen on sodium dodecyl sul...
متن کاملMidkine as a factor to counteract the deposition of amyloid β-peptide plaques: in vitro analysis and examination in knockout mice
BACKGROUND Midkine is a heparin-binding cytokine involved in cell survival and various inflammatory processes. Midkine accumulates in senile plaques of patients with Alzheimer's disease, while it counteracts the cytotoxic effects of amyloid β-peptide and inhibits its oligomerization. The present study was conducted to understand the role of midkine upon plaque formation of amyloid β-peptide. ...
متن کاملMidkine induces tumor cell proliferation and binds to a high affinity signaling receptor associated with JAK tyrosine kinases.
The G401 cell line derived from a rhabdoid tumor of the kidney secretes the heparin-binding growth factors midkine and pleiotrophin. Both proteins act as mitogens for diverse cells, but only midkine serves as an autocrine mitogen for G401 tumor cells. We show that midkine specifically binds a protein or complex of molecular mass greater than 200 kDa with high affinity (Kd = 0.07 +/- 0.01 nM). M...
