Journal ArticleDOI

Widespread requirement for Hedgehog ligand stimulation in growth of digestive tract tumours

TL;DR: A wide range of digestive tract tumours, including most of those originating in the oesophagus, stomach, biliary tract and pancreas, but not in the colon, display increased Hh pathway activity, which is suppressible by cyclopamine, a Hh pathways antagonist.
Journal ArticleDOI

Identification of Gastric Cancer Stem Cells Using the Cell Surface Marker CD44

TL;DR: The existence of gastric CSCs is identified from a panel of human gastric cancer cell lines using cell surface marker CD44 and these cells showed the stem cell properties of self‐renewal and the ability to form differentiated progeny and gave rise to CD44(−) cells.
Journal ArticleDOI

Constitutive activation of the 41-/43-kDa mitogen-activated protein kinase signaling pathway in human tumors

TL;DR: The results suggest that the constitutive activation of 41-/43-kDa MAP kinases in tumor cells is not due to the disorder of MAP kinase themselves, but is due toThe disorder of Raf-1, Ras, or some other signaling molecules upstream of Ras.
Journal ArticleDOI

Characterization of 21 newly established esophageal cancer cell lines

TL;DR: These cell lines are the first reported to be homogeneous and individually unique and may provide a useful model for the study of human esophageal cancer.
