BACKGROUND Matrix-assisted laser desorption/ionization (MALDI) mass spectrometry (MS) has been demonstrated to be useful for molecular profiling of common solid tumors. Using recently developed MALDI matrices for lipid profiling, we evaluated whether direct tissue MALDI MS analysis on proteins and lipids may classify human breast cancer samples according to(More)
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)
We searched for candidate target genes in metastatic gastric cancer, using comparative genomic hybridization (CGH) and mRNA expression array analysis of endoscopic biopsy samples collected from 32 patients. Recurrent amplicons included 17q21.2 (36,569,293–37,307,055), 8q24.13-q24.21 (126,357,475–130,159,285), and 20q13.33 (60,211,249–61,382,787). In this(More)
PURPOSE Hollow fiber assays offer an early in vivo method of anticancer drug screening. The assays have been optimized for human cancers originating from the lung, breast, colon, ovary, and brain, but not from the stomach and liver. The current study focused on optimization of hollow fiber assays for gastric and hepatocellular carcinoma cell lines. (More)
