BACKGROUND Over-expression of long non-coding RNA HOTAIR has been reported in several types of cancer. Yet its involvement in gastric cancer (GC) has not been well understood. The aim of present study was to examine the expression pattern of HOTAIR in GC patients, then, explore its role in promoting cancer invasion and underlying molecular mechanism. (More)
Hepatocellular carcinoma (HCC) is an aggressive disease with poor prognosis and limited methods to predict patient survival. Immune cells infiltrating tumors is known to impact clinical outcome. Here, we investigated the prognostic significance of immune infiltration within the tumor microenvironment in 245 specimens from two independent cohorts by(More)
BACKGROUND 5-Fluorouracil (5Fu) chemotherapy is the first treatment of choice for advanced gastric cancer (GC), but its effectiveness is limited by drug resistance. Emerging evidence suggests that the existence of cancer stem cells (CSCs) contributes to chemoresistance. The aim of the present study was to determine whether 5Fu chemotherapy generates(More)
The existence of microvascular invasion (MVI) formation is one of the most important risk factors predicting poor outcome in hepatocellular carcinoma (HCC) and its mechanism remains largely unknown. Epithelial-Mesenchymal Transition (EMT) has been suggested to be involved in many steps of the invasion-metastasis cascade. To elucidate the possible(More)
BACKGROUND AND OBJECTIVE Gastric stump cancer (GSC) has unique biological behaviors and poor prognosis. The surgical treatment for GSC is complex. This study was to explore the clinical characteristics of GSC and the effect of operation patterns on long-term survival, and investigate its prognostic factors. METHODS The clinical data of 81 GSC patients,(More)
BACKGROUND AND OBJECTIVE The histone deacetylase inhibitor, trichostatin A(TSA), was shown to induce apoptosis in transformed cells at submicromolar concentrations. However, the effect of TSA on brain tumor cells is still unknown. This study was designed to investigate whether TSA posses antitumor activity and if any, its mechanism. MATERIALS AND METHODS(More)
The aim of the present study was to investigate the effect of Huaier on the proliferation and apoptosis of the MKN45 and SGC7901 gastric cancer cell lines. The MTT assay was used to measure the effects of Huaier on the growth of the cells, while cell cycle distribution and apoptosis levels were analyzed using flow cytometry. Western blotting was used to(More)
OBJECTIVE To evaluate the role of vascular resection and reconstruction in the treatment of hilar cholangiocarcinoma. METHODS 117 patients with potentially resectable hilar cholangiocarcinoma underwent exploration. Twenty-one patients had exploration or drainage only due to distant metastases, and the other 96 patients received surgical resection.(More)
Hepatocellular carcinoma is the fifth most common type of cancer worldwide and remains difficult to treat. The aim of this study was to investigate the effects of mesenchymal stem cells (MSCs) derived from the umbilical cord (UC‑MSCs) on HepG2 hepatocellular carcinoma cells. UC‑MSCs were co‑cultured with HepG2 cells and biomarkers of UC‑MSCs were analyzed(More)
The nitrogen mustards are an important class of DNA cross-linking agents, which are utilized in the treatment of many types of cancer. Unfortunately, resistance often develops in the treatment of patients and the tumor either never responds to or becomes refractory to these agents. Resistance to the nitrogen mustards in murine and human tumor cells has been(More)
