We investigated the inhibition of apoptosis and proliferation of poorly differentiated AGS gastric cancer cells by epigallocatechin-3-gallate (EGCG), to establish target genes for regulation by EGCG. The proliferation and apoptosis of AGS gastric cancer cells treated with EGCG were observed by cell counting kit (CCK)-8 and flow cytometry. Differential gene expression in AGS cells treated with E...

Abstract Objectives Cisplatin (DDP) remains to be commonly employed in treating gastric cancer (GC) patients, particularly advanced-stage ones. However, acquired resistance DDP often occurs, which causes a poor prognosis. This study aimed understand the potential contribution of tissue inhibitor metalloproteinase 1 (TIMP1) GC. Methods Bioinformatics analysis was performed explore relation TIMP1...

Epstein-Barr virus (EBV) is associated with human cancers such as nasopharyngeal carcinoma, Burkitt's lymphoma, Hodgkin's disease, and gastric carcinoma (GC). EBV is associated with about 10% of all GC cases globally. EBV-associated GC has distinct features from EBV-negative GC. However, it is still unclear if EBV infection has any effect on GC chemoresistance. Cell proliferation assay, cell cy...

Comparative study of alloimmune responses against major and minor histocompatibility Ags has been limited by the lack of suitable assays. Here, we use a bioassay that permits tracking of alloreactive CD4+ T cell populations as they proliferate in response to major or minor histocompatibility Ags in vivo. Division of alloreactive CD4+ T cells proceeded more rapidly in response to major histocomp...

Abnormal expression of the kallikrein (KLK) family of serine proteases closely correlates with onset, progression, and prognosis of endocrine gland-related malignant tumors. The aim of this study was to evaluate how downregulation of KLK12 influenced cell cycle and proliferation of the AGS gastric cancer cell line. KLK12 was detected by western blot in GES-1 normal gastric epithelial and AGS ce...

Background: Lactoferrin is a glycoprotein with a molecular weight of 80 kDa, as a member of the transferring family. In recent investigations the important biological properties such as anti microbial, antiviral and anticancer activity of lactoferrin were studied. In the present study, the effect of antitumor induced by lactoferin was evaluated on stomach cancer cell AGS. Materials and Methods...

The expression of activated cell antigens (Ags) on adult T cell leukemia (ATL) cells at different clinical stages (acute, chronic, and smoldering), and ATL cells from enlarged lymph nodes were studied using monoclonal antibodies (MoAbs). The expressions of CD25 (Tac), CD28, T9 (transferrin receptor), and Ki-67 (proliferating cell nuclear antigen) Ags were high, and that of CD7 Ag was low in bot...
