To observe the expression of α-Enolase( ENO1) correlated with the pathological progression of gastric cancer and to investigate the effects of ENO1 down-regulation on the proliferative and migratory abilities of gastric cell lines in vitro. The expression of ENO1 was detected in 22 cases of gastric cancer, 20 cases of atypical hyperplasia and 18 cases of normal gastric tissues by immunohistoche...

We previously identified a distinct mutation pattern in the antibody genes of B cells isolated from cerebrospinal fluid (CSF) that can identify patients who have relapsing-remitting multiple sclerosis (RRMS) and patients with clinically isolated syndromes who will convert to RRMS. This antibody gene signature (AGS) was developed using Sanger sequencing of single B cells. While potentially helpf...

OBJECTIVES Rheum undulatum L. has traditionally been used for the treatment of many diseases in Asia. However, its anti-proliferative activity in cancer has still not been studied. In the present study, we investigated the anti-cancer effects of methanol extract of Rheum undulatum L. (MERL) on human adenocarcinoma gastric cell lines (AGS). METHODS To investigate the anti-cancer effect of MERL...

BACKGROUND Resistin-like molecule-β (RELMβ) is a novel secretory protein from intestinal goblet cells and participates in epithelial differentiation, tumor occurrence, and immune response. RELMβ is absent in normal gastric mucosa but is abundantly expressed in gastric carcinoma tissues, and is correlated with tumor invasion and metastasis. Epithelial-mesenchymal transition (EMT) is an important...

BACKGROUND The gastric epithelium is continuously exposed to toxic reactive oxygen species and matrix metalloproteinases (MMPs) are the enzymes known for their roles in the invasion of tumor cells. Here, we report the suppression of matrix metalloproteinase 3 (MMP-3) in gastric cancer cell line AGS by small interfering RNA (siRNA) transfection and its potential role in gastric cancers. METHOD...

B cells express randomly rearranged surface Ig that forms part of a multiprotein complex known as the B cell receptor (BCR). Recognition of Ag via this receptor results in its capture, internalization, proteolysis and presentation to CD4+ T cells. The recognition of Ag by CD4+ T cells is critical for the selection of individual B cells, leading to the eventual secretion of a high affinity versi...
