Gastric cancer (GC) is the most common epithelial malignancy worldwide. Basic transcription factor 3 (BTF3) plays a crucial role in the regulation of various biological processes. We designed experiments to investigate the molecular mechanism underlying the role of BTF3 in GC cell proliferation and metastasis. We confirmed that BTF3 expression was decreased in GC tissues and several GC cell lines. Lentivirus-mediated downregualtion of BTF3 reduced cell proliferation, induced S and G2/M cell cycle arrest, and increased apoptosis...

BACKGROUND AND AIMS: Growing evidence suggests that microRNA plays an essential role in the development and metastasis of many tumors, including gastric cancer (GC). Expression of microRNA-203 (miR-203) has been reported to decrease in GC. In addition, overexpression of miR-203 inhibits grow of GC cells in vitro and in vivo. However, whether miR-203 affects cell migration and invasion of GC remains unclear. This study aimed to reveal the role of miR-203 on migration and invasion of GC, and its potential mechanisms...

Outcomes of patients with gastric cancer who exhibit positive peritoneal lavage cytology findings (CY(+) ) vary by diagnostic methods because of quantitative and qualitative cancer cell diversity. This study sought to establish practical diagnostic criteria for performing curative resections, based on peritoneal lavage cytology findings in gastric cancer patients. We enrolled 1028 patients with gastric cancer who underwent R0/1 (n=911) or R2 (n=117) resections and analyzed relationships between cancer cell findings in peritoneal lavage fluid and clinicopathological factors in the R0/1 group...

CUB domain-containing protein-1 (CDCP1) is a trans-membrane protein predominantly expressed in various cancer cells and involved in tumor progression. CDCP1 is phosphorylated at tyrosine residues in the intracellular domain by Src family kinases and recruits PKCδ to the plasma membrane through tyrosine phosphorylation-dependent association with the C2 domain of PKCδ, which in turn induces a survival signal in an anchorage-independent condithion. In this study, we utilized our cell-free screening system to identify a small compound, glycoconjugated palladium complex (Pd-Oqn), which significantly inhibited the interaction between the C2 domain of PKCδ and phosphorylated CDCP1...

Cancer-associated fibroblasts (CAFs), as the activated fibroblasts in tumor stroma, are important modifiers of tumor progression. However, the molecular mechanisms underlying the tumor-promoting properties of CAFs in gastric cancer remain unclear. Here, we show that CAFs isolated from gastric cancer produce significant amounts of interleukin-6 (IL-6). CAFs enhances the migration and EMT of gastric cancer cells through the secretion of IL-6 that activates Janus kinase 2/signal transducers and activators of transcription (JAK2/STAT3) pathway in gastric cancer cells, while deprivation of IL-6 using a neutralizing antibody or inhibition of JAK/STAT3 pathway with specific inhibitor AG490 markedly attenuates these phenotypes in gastric cancer cells induced by CAFs...

Disseminated metastasis is associated with a poor prognosis, and its management in the peritoneal or pleural cavity is crucial in the treatment of cancer. Recent studies show that ion and water transporters play important roles in fundamental cellular functions, including the regulation of cell volume that would be involved in the cancer process. Here, we review the evidence for hypotonic treatments of cancer and evaluate the potential of the cellular physiological approach in clinical management. The regulation of extracellular osmolality is a promising method, with several studies demonstrating the cytocidal effects of hypotonic solution on cancer cells...

A woman in her 60s was admitted to our hospital with pain and induration of the navel. She was diagnosed with gastric cancer with metastasis to the navel and underwent total gastrectomy and navel extraction. Because disseminated nodules were detected in the Douglas pouch and sigmoid colon, sigmoidectomy was performed to prevent bowel obstruction. The navel tumor was histologically diagnosed as a metastasis of the gastric cancer. One month after surgery, a chest skin tumor, which was also a skin metastasis of the gastric cancer[T4aN3M1(SKI, OTH)H0P1, fStage IV ], was detected, and tumor enucleation was performed...

Malignant ascites manifests as an end-stage event during the progression of a number of cancers and lacks a generally accepted standard therapy. Interferon-β (IFN-β) has been used to treat several cancer indications; however, little is known about the efficacy of IFN-β on malignant ascites. In the present study, we report on the development of a novel, engineered form of human and murine IFN-β, each conjugated with a polyethylene glycol molecule (PEG-hIFN-β and PEG-mIFN-β, respectively). We provide evidence that these IFN-β molecules retain anti-viral potency comparable to unmodified IFN-β in vitro and manifested improved pharmacokinetics in vivo...
