Resent studies have identified Pygopus as a core component of the β-catenin/T-cell factor (TCF)/lymphoid-enhancing factor 1 (LEF) transcriptional activation complex required for the expression of canonical Wg/Wnt target genes in Drosophila. However, the biochemical involvement of mammalian Pygopus proteins in β-catenin/TCF/LEF gene activation remains(More)
Genistein, the predominant isoflavone found in soy products, has exerted its anticarcinogenic effect in many different tumor types in vitro and in vivo. Accumulating evidence in recent years has strongly indicated the existence of cancer stem cells in gastric cancer. Here, we showed that low doses of genistein (15 µM), extracted from Millettia nitida Benth(More)
We detected aberrant Midkine (MK) expressions in human insulinoma and pancreatic cancer tissues by immunohistochemistry, revealing its potential role in tumorigenesis/carcinogenesis. With a nested-touchdown PCR program we were able to detect the tMK in all human tumor/cancer tissues and cancer/tumor cell lines. Detection of MK in the peripheral cells and(More)
Cancer stem cells possess self-renewal and chemoresistance activities. However, the manner in which these features are maintained remains obscure. We sought to identify cell surface protein(s) that mark self-renewing and chemoresistant gastric cancer cells using the explorer antibody microarray. We identified PMP22, a target gene of the Wnt/β-catenin(More)
