Barrett's esophagus (BE) is an intestinal metaplasia that occurs in the setting of chronic acid and bile reflux and is associated with a risk for adenocarcinoma. Expression of intestine-specific transcription factors in the esophagus likely contributes to metaplasia development. Our objective was to explore the effects of an intestine-specific transcription factor when expressed in the mouse es...
Polycomb Repressive Complex (PRC) 1 regulates the control of gene expression programs via chromatin structure reorganization. Through mutual exclusion, different PCGF members generate a variety of PRC1 complexes with potentially distinct cellular functions. In this context, the molecular function of each of the PCGF family members remains elusive. The study of PCGF family member expression in z...
PURPOSE The importance of Helicobacter pylori eradication after endoscopic resection (ER) of gastric neoplasms remains controversial. In this study, we clarified the importance of H. pylori eradication for metachronous lesions after ER. MATERIALS AND METHODS This study included 3,882 patients with gastric neoplasms who underwent ER. We included patients infected with H. pylori who received er...
BACKGROUND Studies in many model systems have shown that canonical signaling through the pathway downstream of ligands of the Wnt family can regulate multiple steps in organogenesis, including cell proliferation, differentiation, and lineage specification. In addition, misexpression of the Wnt-family member Wingless in Drosophila imaginal disc cells can lead to transdetermination of progenitors...
BACKGROUND CTCs are a promising alternative for metastatic tissue biopsies for use in precision medicine approaches. We investigated to what extent the molecular characteristics of circulating tumor cells (CTCs) resemble the liver metastasis and/or the primary tumor from patients with metastatic colorectal cancer (mCRC). RESULTS The CTC profiles were concordant with the liver metastasis in 17...
The morphology and infraciliature of the type species of the ciliate genus Trachelostyla, T. pediculiformis (Cohn, 1866) Borror, 1972, collected from the Bohai Sea near Tianjin, north China, were investigated using live observation and protargol impregnation. The Chinese population corresponds well with the original description, as follows: size about 80-150 x 20-30 microm in vivo; body dorsove...
Background and aims: Although it has been reported that intestinal metaplasia implicated in gastric carcinogenesis is induced by the ParaHox gene CDX2, it is unclear which genes are responsible for the formation of pseudopyloric glands and whether they play a role in gastric carcinogenesis. Pancreaticduodenal homeobox 1 (PDX1) is also a ParaHox gene which contributes to the genesis and developm...
Knowledge of human pancreas development underpins our interpretation and exploitation of human pluripotent stem cell (PSC) differentiation toward a β-cell fate. However, almost no information exists on the early events of human pancreatic specification in the distal foregut, bud formation, and early development. Here, we have studied the expression profiles of key lineage-specific markers to un...
The classic TS phenotype includes short stature, gonadal dysgenesis with primary amenorrhea and hypergonadotropic hypogonadism, facial and body dysmorphisms, skeletal abnormalities, cardiovascular and renal malformations, and predisposition to autoimmune diseases, such as thyroid diseases, diabetes mellitus, celiac disease, and vitiligo.21 Short stature is always present and is caused by severa...
