Therapeutic efficacy of a synthetic epsin mimetic peptide in glioma tumor model: uncovering multiple mechanisms beyond the VEGF-associated tumor angiogenesis.
Article in Journal of neuro-oncology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Binding of epsin ubiquitin-interacting motif (UIM) with ubiquitylated VEGFR2 is a critical mechanism for epsin-dependent VEGFR2 endocytosis and physiological angiogenesis. Deletion of epsins in vessel endothelium produces uncontrolled tumor angiogenesis and retards tumor growth in animal models. The aim of this study is to test the therapeutic efficacy and targeting specificity of a chemically-synthesized peptide, UPI, which compete for epsin binding sites in VEGFR2 and potentially inhibits Epsin-VEGFR2 interaction in vivo, in an attempt to reproduce an epsin-deficient phenotype in tumor angiogenesis. Our data show that UPI treatment significantly inhibits and shrinks tumor growth in GL261 glioma tumor model. UPI peptide specifically targets VEGFR2 signaling pathway revealed by genetic and biochemical approaches. Furthermore, we demonstrated that UPI peptide treatment caused serious thrombosis in tumor vessels and damages tumor cells after a long-term UPI peptide administration. Besides, we revealed that UPI peptides were unexpectedly targeted cancer cells and induced apoptosis. We conclude that UPI peptide is a potent inhibitor to glioma tumor growth through specific targeting of VEGFR2 signaling in the tumor vasculature and cancer cells, which may offer a potentially novel treatment for cancer patients who are resistant to current anti-VEGF therapies.
