BACKGROUND: Ring finger protein 43 (RNF43) is a member of the transmembrane E3 ubiquitin ligase family that was originally found in stem cells and plays important roles in tumor formation and progression. Our previous study indicated that RNF43 might be a tumor suppressor protein in gastric cancer. Given its antagonistic relationship with leucine-rich repeat-containing G-protein-coupled receptor 5 (Lgr5), one of the gastric cancer stem cell markers, investigation of the potential role of RNF43 in gastric stem cancer cells is necessary...

MicroRNAs (miRNAs) are internal, noncoding, and ∼22 nt small RNAs that display cell- and tissue-specific expression. They play important regulatory roles in cell proliferation and chemo-sensitivity. This study focused on tumor-suppressive miR-33b-5p expression as well as its role in gastric cancer. MiR-33b-5p was found low expression in gastric cancer cell lines. Functionally, western blots and the luciferase reporter assay were used to confirme that HMGA2 was the potential target of miR-33b-5p. Next, we used CCK-8 kits to analyze the effect of miR-33b-5p combined chemotherapy drugs on cell inhibition rate, and flow cytometry to analyze cells apoptosis...

BACKGROUND: Due to a lack of consensus on adjuvant treatments for pT1N1 gastric cancer, surgeons face a dilemma when deciding treatments for patients with pT1N1 gastric cancer after gastrectomy. The objective of this study was to determine survival benefits of adjuvant chemotherapy and risk factors for tumor recurrence in gastric cancer patients with pT1N1. METHODS: Between 1996 and 2010, 510 patients who underwent curative resection for pT1N1 gastric cancer at three institutes were divided into two groups: adjuvant chemotherapy group (N = 150) and surgery-only group (N = 360)...

Lots of controversies were found about the treatment in relation to radiation therapy (RT) for esophageal squamous cell carcinoma (ESCC). We designed a questionnaire of these controversies to do a pan-Chinese survey of radiation oncologists (ROs). For operable ESCC, 53% ROs chose surgery plus postoperative chemoradiotherapy (CRT), while 40% chose preoperative CRT plus surgery. For target volume of postoperative RT, most ROs (92%) would delineate tumor bed plus involved lymph nodes region before surgery. For definitive RT, most ROs (81%) would give patients higher RT dose to 60-65Gy...

The current systemic treatments of the various solid tumors involve Cisplatin (CIS)-based chemotherapy. Due to its cytotoxicity, this approach is limited. Moreover, the safety of CIS is only discussed especially in breast and stomach cancers. Therefore, we, for the first time, explored the restorative efficacy of oleuropein (OLE), in stomach and lung injuries induced by CIS. Sprague-Dawley rats were divided into eight groups: control CIS, OLE and CIS + OLE. Single dose of (7 mg/kg) CIS was administered intraperitoneally to CIS and CIS + OLE groups...

Gastric leiomyosarcoma is a recalcitrant cancer and chemotherapy strategy is controversial. The present study used a patient-derived orthotopic xenograft (PDOX) nude mouse model of gastric leiomyosarcoma to identify an effective therapeutic regimen in order to develop individualized precision medicine for this disease. A gastric leiomyosarcoma obtained from a patient was first grown in transgenic nude mice ubiquitously expressing red fluorescent protein (RFP) in order to stably label the tumor stroma. The RFP-expressing tumor was then passaged orthotopically in the gastric wall of non-transgenic nude mice to establish an imageable PDOX (iPDOX) model...

BACKGROUND: Accumulating evidence suggests that regulatory B cells (Bregs) play an important role in modulating the immune response to tumours. Our previous study indicated that a small percentage of peripheral CD19+CD24hCD27+ Breg cells slowed gastric cancer progression in XELOX-treated patients. Here, we further investigated the relationship between dynamic changes in circulating Breg cells and the clinical course in XELOX-treated gastric cancer patients. METHODS: A total of 52 patients with advanced gastric cancer were enrolled in this study...
