UNLABELLED Loss of E-cadherin (CDH1), Smad4, and p53 has been shown to play an integral role in gastric, intestinal, and breast cancer formation. Compound conditional knockout mice for Smad4, p53, and E-cadherin were generated to define and compare the roles of these genes in gastric, intestinal, and breast cancer development by crossing with Pdx-1-Cre,(More)
There is a strong need for murine gastric cancer cell line models recapitulating human gastric cancers. Here, we describe two murine gastric cancer cell lines designated as NCC-S1 and NCC-S3. They were generated from gastric adenocarcinomas that formed in a Villin-cre, Smad4(F/F) , Trp53(F/F) , Cdh1(F/wt) mouse and a Pdx1-cre, Trp53(F/F) , Cdh1(F/F) mouse,(More)
The rate of donations made by individuals is relatively low in Korea when compared to other developed countries. To address this problem, we propose the DONA, an urban donation motivating robot prototype. The robot roams around in a public space and solicits donation from passers-by by engaging them through a pet like interaction. In this paper, we present(More)

A simple, fast and reliable high-performance liquid chromatography-triple quadrupole mass spectrometry method (HPLC-MS/MS method) was developed, validated and used for the simultaneous quantification of irinotecan and 7-ethyl-10-hydroxycamptothecin (SN38) in heparinized mouse plasma. Camptothecin was used as the internal standard. A single-step protein(More)
There is an increasing need for more sensitive analytical methods in pharmacokinetic studies, for example, for phase 0 clinical trials. A novel HPLC Chip-triple quadrupole mass spectrometer method (HPLC Chip-MS/MS method) for the quantification of 7-ethyl-10-hydroxycamptothecin (SN38) was developed, validated, and employed to the pharmacokinetic analysis of(More)
There is a strong need to identify markers to enrich gastric cancer stem cells (CSCs). However, CSC enrichment markers for mouse gastric cancers have not yet been determined. In our previous study, we generated primary mouse gastric cancer cell line NCC-S1 (S1) established from a Villin-cre;Smad4(F/F) ;Trp53(F/F) ;Cdh1(F/wt) mouse and its metastatic variant(More)
