Objective(s):MiRNAs have been proposed to be key regulators of tumorigenesis, progression and metastasis. However, their effect and prognostic value in gastric cancer is still poorly known. Materials and Methods: Gastric cancer cell lines were cultured. Tissue samples obtained from 36 gastric cancer patients were used for quantitative real-time PCR (qRT-PCR) analysis. The tissue microarrays (T...

Previous studies have shown that pigment epithelium-derived factor (PEDF) is an antitumor candidate with anti-oxidative, anti-inflammatory and anti-angiogenesis properties. However, the effect of PEDF on gastric carcinoma has not been elucidated. MTT assay and Annexin V/PI staining were performed. Immunohistochemistry was applied to detect microvessel density (MVD) of a xenograft model. The pro...

BACKGROUND AND AIMS In the progression of chronic gastritis, gastric mucosal cells deviate from the normal pathway of gastric differentiation to an intestinal phenotype which is closely related to gastric carcinoma. However, to date, it has not been elucidated whether the intestinal metaplasia is merely a change in the epithelium or whether the underlying mesenchyme also changes from gastric ty...

Since gastric carcinoma, unlike uninvaded mucosa, has a relatively high glycogen content and the risk of gastric carcinoma is especially high in patients with a partially resected stomach, the aim of this study was to follow glycogen storage in both uninvaded gastric stump mucosa and carcinoma developing in the stump postsurgery performed for benign and malignant conditions. One hundred patient...

PURPOSE Cyclooxygenase-2 (COX-2) is believed to be involved in carcinogenesis in patients with chronic gastritis with Helicobacter pylori infection. EBV is detected in approximately 10% of gastric carcinomas and H. pylori induces EBV reactivation in the gastric epithelium. We aimed to evaluate significance of COX-2 in gastric carcinoma occurred in EBV and H. pylori prevalent area. EXPERIMENTA...

We report a case of gastric signet cell carcinoma, presenting as cardiac tamponade, in a young male patient. The diagnosis of gastric signet cell carcinoma was confirmed by immunohistochemistry of the lymph node specimen in our patient.

Background and aims: In the progression of chronic gastritis, gastric mucosal cells deviate from the normal pathway of gastric differentiation to an intestinal phenotype which is closely related to gastric carcinoma. However, to date, it has not been elucidated whether the intestinal metaplasia is merely a change in the epithelium or whether the underlying mesenchyme also changes from gastric t...

As one of the common malignant tumors that threaten human health severely, gastric carcinoma is the second highest cause of cancer death and the fourth most common cancer globally. However, the mechanism underlying gastric cancer is still not fully understood. PABPC1 plays an important role in translation, control the rate of mRNA deadenylation and participates in mRNA decay, which is involved ...

Primary gastric carcinoma is the most common cause of linitis plastica. Less frequently, metastatic gastric cancer from the breast, omental metastases and non-Hodgkin lymphoma involving the stomach have been reported to show similar radiographic findings as for linitis plastica. A metastatic gastric cancer from bladder cancer is extremely rare. We present an unusual case, the first to our knowl...

BACKGROUND Determining levels of tumor markers in peritoneal washing enables likelihood of peritoneal recurrence to be ascertained in patients with high marker levels, thereby allowing provision of more accurate adjuvant treatment and postoperative follow up. AIM To analyze the relationship between levels of tumor marker CA72-4 in serum and peritoneal washing, and morphological aspects of gas...
