BACKGROUNDS: Hepatocellular carcinoma (HCC) is an epithelial cancer that originates from hepatocytes and it is the most common primary malignant tumor of the liver. Till now the prognosis of HCC patients is generally poor. The molecular mechanism giving rise to HCC development and recurrence is still largely unknown. MicroRNA-31 (miR-31) is among the most commonly altered microRNAs in human cancers, and alternations of miR-31 expression were reported to play pivotal roles in tumorigenesis and tumor progression...

BACKGROUNDS: Cancer progression has been associated with host hemostasis system. Whether preoperative plasma hemostasis factors can predict survival in colorectal cancer is quite intriguing. METHODS: We conducted a prospective cohort study to validate the prognostic significance of three hemostasis parameters - fibrinogen, fibrin degradation products (FDPs) and D-dimer - in non-metastatic colorectal cancer patients treated with curative resection. RESULTS: All three parameters were positively correlated with C reactive protein (CRP) levels and Glasgow Prognostic scores (GPS)...

Esophageal cancer is a common cause of cancer-related deaths worldwide. Squamous cell carcinoma (SCC) is the major histological type of esophageal cancer in developing countries including China, and the prognosis is very poor. Many microRNAs are involved in several important biological and pathologic processes, and promote tumorigenesis. To better understand the prognostic and therapeutic roles of microRNAs in ESCC, we reviewed the diagnosis and prognosis associated oncogenic microRNAs (e.g. miR-21 and miR-17-92 cluster) and tumor suppressor microRNAs (e...

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...

Prostate cancer (PCa) was one of the most common cancers in males in China. Long non-coding RNAs (lncRNA), a class of non-coding RNAs with more than 200 nucleotides, played key roles in the progression of prostate cancer. GLIDR, a novel long intergenic ncRNA, was found to be upregulated in tumors compared to normal tissues by using publically databases. In the clinical validation cohort, our results showed GLIDR was significantly up-regulated in prostate cancer samples and cell lines. To explore the potential functions of the GLIDR, we constructed gene co-expression networks and applied GO analysis...
