To reduce the colorectal cancer (CRC) mortality rate, we have reported several CRC screening methods using colonocytes isolated from feces. Expression analysis of oncogenic microRNA (miRNA) in peripheral blood was recently reported for CRC detection. In the present study, we conducted miRNA expression analysis of exfoliated colonocytes isolated from feces(More)
Recent published reports on clinical trials of CPT-11 indicate the effectiveness of this compound, a prodrug of SN-38, against malignant glioma in combination with anti-vascular endothelial growth factor antibody. Here, we determined if NK012, and SN-38 incorporating micelle, can be an appropriate formulation for glioblastoma treatment compared with CPT-11.(More)
Human pancreatic cancer is generally hypovascular in nature and rich in interstitium. These pathological barriers may contribute to the intractable nature of pancreatic cancer by binding the penetration of anticancer agents throughout the tumor tissue. The aim of the present study was to determine whether NK012 is an appropriate formulation for the(More)
The combination therapy of CPT-11, a prodrug of SN-38, with S-1, a dihydropyrimidine dehydrogenase inhibitory fluoropyrimidine, shows a high clinical response rate in non-small cell lung cancer (NSCLC). However, this combination causes severe toxicities such as diarrhea. Here, we investigated the advantages of treatment with the SN-38-incorporating(More)
PURPOSE To clarify the effect of bevacizumab on NK012 therapy in mice bearing U87MG glioblastoma orthotopic xenografts in comparison with the combination therapy of irinotecan hydrochloride (CPT-11) with bevacizumab. EXPERIMENTAL DESIGN NK012 at 7-ethyl-10-hydroxycamptothecin (SN-38) equivalent dose of 30 mg/kg was administered intravenously three times(More)
PURPOSE To clarify and compare the antitumor effects and specific biodistribution of NK012, an SN-38-incorporating polymeric micelle, in mice bearing multiple liver metastases of human colon cancer HT-29 cells with irinotecan hydrochloride (CPT-11). EXPERIMENTAL DESIGN The maximum tolerable dose of NK012 (30 mg/kg) or CPT-11 (66.7 mg/kg) was i.v.(More)
PURPOSE To investigate the advantages of treatment with the SN-38-incorporating polymeric micelles NK012 over CPT-11 in combination with cisplatin [cis-dichlorodiammineplatinum (II) (CDDP)] in mice bearing a small cell lung cancer xenograft in terms of antitumor activity and toxicity, particularly intestinal toxicity. EXPERIMENTAL DESIGN Cytotoxic effects(More)
Human pancreatic cancer is refractory to chemotherapy partly because of blockage to penetration of anticancer agents. This issue must be taken into account particularly for the drug delivery system (DDS). The aim of the present study is to investigate how NK012 (SN-38-incorporating polymeric micelles) categorised as DDS exerts its antitumour effect in an(More)
BACKGROUND It has been demonstrated that NK012, a novel 7-ethyl-10-hydroxycamptothecin (SN-38)-incorporating polymeric micelle, exerts significantly more potent antitumor activity against various human tumor xenografts than irinotecan (CPT-11) (a water-soluble prodrug of SN-38). Combination therapy of anticancer agents with bevacizumab (Bv), an(More)
Epirubicin is widely used to treat various human tumors. However, it is difficult to achieve a sufficient antitumor effect because of dosage limitation to prevent cardiotoxicity. We hypothesized that epirubicin-incorporating micelle would reduce cardiotoxicity and improve the antitumor effect. NC-6300 comprises epirubicin covalently bound to PEG(More)
