materials and methods an oligogearray® (an oligonucleotide-based gene expression array platform) containing 126 wnt signaling pathway-related genes was used to compare gene expressions between primary hcc and adjacent non-tumorous liver tissues from 10 patients with hcc. selected differential genes were identified with real-time rt-pcr and immunohistochemistry (ihc). in particular, the protein ...

Direct tissue profiling and imaging mass spectrometry (MS) allow for detailed mapping of the complex protein pattern across a tissue sample. Utilization of these tools provides spatial information across a tissue section for target protein expression and can be used to correlate changes in expression levels with specific disease states or drug response. Protein patterns can be directly correlat...
