Deregulated microRNAs participate in carcinogenesis and cancer progression, but their roles in cancer development remain unclear. In this study, miR-365 expression was found to be downregulated in human colon cancer tissues as compared with that in matched non-neoplastic mucosa tissues, and its downregulation was correlated with cancer progression and poor(More)
Deregulated microRNAs and their roles in cancer development have attracted much attention. In the present study, we analyzed the roles of miR-195 in colorectal cancer pathogenesis, as its participation in some other types of cancer has been suggested by previous reports. By comparing miR-195 expression in 81 human colorectal cancer tissues and matched(More)
PURPOSE The safety and efficacy of radical laparoscopic distal gastrectomy (LG) with D2 lymphadenectomy for the treatment of advanced gastric cancer (AGC) remain controversial. We conducted a randomized controlled trial to compare laparoscopic and conventional open distal gastrectomy with D2 lymph node dissections for AGC. PATIENTS AND METHODS Between(More)
Transforming growth factor (TGF)-β/Smad signaling plays an important role in colon cancer development, progression and metastasis. In this study we demonstrated that the microRNA-130a/301a/454 family is up-regulated in colon cancer tissues compared to paired adjacent normal mucosa, which share the same 3'-untranslational region (3'-UTR) binding seed(More)
Laparoscopy-assisted gastrectomy (LAG) has been indicated to be safe, feasible, and oncologically efficacious for the treatment of early gastric cancer by both retrospective and prospective studies. Although some reports have demonstrated that LAG was also a safe and technically feasible procedure for advanced gastric cancer (AGC), its oncologic outcomes(More)
Addition of immunoregulation factor to an oncolytic adenovirus being constructed is a developmental step in tumor gene therapy; however, cytokine IL-15 has not been frequently used as a potential cancer therapy agent. Here, we constructed an E2F-1 promoter oncolytic adenovirus based on type 5 adenovirus, which induces viral replication and proliferation in(More)
BACKGROUND We previously showed that the fatty liver formations observed in overfed geese are accompanied by the activation of the PI3K-Akt-mTOR pathway and an increase in plasma insulin concentrations. Recent studies have suggested a crucial role for the PI3K-Akt-mTOR pathway in regulating lipid metabolism; therefore, we hypothesized that insulin affects(More)
The neoadjuvant therapy has significantly improved the outcome of locally advanced resectable T3 rectal cancer patients. Actually, only a portion of patients show sensitivity to the preoperative chemoradiation and benefit markedly from this treatment. However, biomarkers for predicting neoadjuvant therapy sensitivity remain unclear. In this study, through(More)
In vivo engineering of hepatic tissue based on primary hepatocytes offers new perspectives for the treatment of liver diseases. However, generation of thick, three-dimensional liver tissue has been limited by the lack of vasculature in the tissue-engineered constructs. Here, we used collagen hydrogel as a matrix to generate engineered hepatic units to(More)
Peutz Jeghers syndrome (PJS) is an autosomal dominant disease caused by mutations in the LKB1 gene. We screened for the LKB1 gene mutation in a Chinese PJS patient. Sequence analysis of LKB1 exons showed that there was a novel de novo mis-sense mutation of codon 16 (GAG to GGG) in exon 1 in LKB1 gene in the Chinese PJS patient. Furthermore, we observed that(More)
