Lenvatinib is an oral inhibitor of multiple receptor tyrosine kinases (RTKs) targeting vascular endothelial growth factor (VEGFR1-3), fibroblast (FGFR1-4), platelet α (PDGFR α), RET and KIT. Antiangiogenesis activity lenvatinib in VEGF- FGF-driven angiogenesis models both vitro vivo was determined. Roles tumor vasculature (microvessel density (MVD) pericyte coverage) as biomarkers for were also examined this study.We evaluated antiangiogenesis against proliferation tube formation HUVECs...
Eribulin mesylate is a synthetic macrocyclic ketone analog of the marine sponge natural product halichondrin B and an inhibitor microtubule dynamics. Some tubulin-binding drugs are known to have antivascular (antiangiogenesis or vascular-disrupting) activities that can target abnormal tumor vessels. Using dynamic contrast-enhanced MRI analyses, here we show eribulin induces remodeling vasculature through novel activity in MX-1 MDA-MB-231 human breast cancer xenograft models. Vascular...
Abstract The Wnt/β-catenin signaling pathway plays crucial roles in embryonic development and the of multiple types cancer, its aberrant activation provides cancer cells with escape mechanisms from immune checkpoint inhibitors. E7386, an orally active selective inhibitor interaction between β-catenin CREB binding protein, which is part pathway, disrupts HEK293 adenomatous polyposis coli (APC)-mutated human gastric ECC10 cells. It also inhibited tumor growth xenograft model suppressed polyp...

Oral administration significantly inhibited basic fibroblast growth factor-induced Matrigel implants colon WiDr tumor-induced dorsal air sac...
Vascular endothelial growth factor receptor (VEGFR) inhibitors are approved for the treatment of several tumor types; however, some tumors show intrinsic resistance to VEGFR inhibitors, and patients develop acquired these inhibitors. Therefore, a strategy overcome inhibitor is urgently required. Recent reports suggest that activation hepatocyte (HGF) pathway through its cognate receptor, Met, contributes resistance. Here, we explored effect HGF/Met signaling on lenvatinib, inhibitor. In in...

Large (GP1) small (GP2) glycoproteins lipids seemed to be required expression particles. Potential haemolysin associated GP2. A relatively high proportion GP1 formation a activity. When top lipid fraction (Hosaka & Shimizu, 1972a) used reassembly, usually...

Nuclear proteins contain a signal, termed the nuclear transport that specifies their selective into nucleus. Previously we reported antibodies to Asp-Asp-Asp-Glu-Asp (DDDED) inhibited of in vivo. We therefore tried detect cellular receptor signals as protein reacted with both anti-DDDED antibody and signal sequences. Using two steps affinity chromatography, anti-DDDED-Sepharose nucleoplasmin-Sepharose, obtained 69 kDa (p69) from pore fraction showed these characters. This p69 recognized by...
We report the dose-escalation part of a phase I study liposomal eribulin (E7389-LF) in Japanese patients with advanced solid tumors and no alternative standard therapy.
Most non-small-cell lung cancers (NSCLCs) harboring activating mutations in the epidermal growth factor receptor (EGFR) are initially responsive to EGFR tyrosine kinase inhibitors (EGFR-TKIs); however, they invariably develop resistance these drugs. E7820 is an angiogenesis inhibitor that decreases integrin-α2 expression and currently undergoing clinical trials. We investigated whether combination with erlotinib, EGFR-TKI, could overcome EGFR-TKI-resistance NSCLC cell lines A549 (KRAS;...
E7820 is an orally active inhibitor of α(2)-integrin mRNA expression, currently tested in phases I and II. We aimed to evaluate what levels inhibition integrin expression are needed achieve tumor stasis mice, compare this the level achieved humans. Tumor growth was measured mice bearing a pancreatic KP-1 tumor, dosed at 12.5-200 mg/kg over 21 days. In phase study, administered daily for 28 days range 0-200 mg, followed by 7-day washout period. PK-PD models were developed NONMEM....
