BACKGROUND & AIMS Altered functions of microRNAs (miRNAs) have been associated with colorectal cancer (CRC). miR-212 is transcribed from a stable intron of a non-protein coding gene, and is reportedly down-regulated in different tumor types. We investigated the role of miR-212 in colorectal carcinogenesis and progression. METHODS We analyzed the(More)
Overexpressed DNA methyltransferase 1 (DNMT1) strongly contributes to tumor suppressor gene silencing in colorectal cancer (CRC). However, the underlying mechanism of DNMT1 overexpression is still unclear. MicroRNAs (miRNA) have been implicated as gene regulators controlling diverse biological processes, including carcinogenesis. In this study, we(More)
BACKGROUND Hypoxic tumor cells can reduce the efficacy of radiation. Antiangiogenic therapy may transiently "normalize" the tumor vasculature to make it more efficient for oxygen delivery. The aim of this study is to investigate whether the recombinant human endostatin (endostar) can create a "vascular normalization window" to alleviate hypoxia and enhance(More)
BACKGROUND Nonviral vectors are attractively used for gene therapy owing to their distinctive advantages. Our previous study has demonstrated that transfer of human IFNγ gene into nasopharyngeal carcinoma (NPC) by using a novel nonviral vector, minicircle (mc), under the control of cytomegalovirus (CMV) promoter was effective to inhibit tumor growth.(More)
Viral fusogenic membrane glycoproteins (FMGs) are new therapeutic genes for the control of tumor growth, the cellular mechanisms mediating cell death is non-apoptotic. However, the precise molecular mechanism remains to be elucidated. Here, we showed overexpression of HSP70 in HL-60 cells mediated by Gibbon Ape leukemia virus hyperfusogenic envelope protein(More)
The aim of this study was to investigate the effect of microRNA-20a on pancreatic carcinoma cell proliferation and invasion and to find a new effective treatment strategy for pancreatic carcinoma. MicroRNA-20a expression was determined in 10 matched normal pancreatic tissues and pancreatic carcinoma by in situ hybridization. Quantitative real-time RT-PCR(More)
Nasopharyngeal carcinoma (NPC) is a leading cause of cancer-related mortality. Radiotherapy is one of the primary modalities for NPC treatment. However, in patients in the late stages of the disease, the local control rate and overall survival rate remain low. Therefore, it is urgent to identify new targets that can improve the outcome of radiotherapy in(More)
Nasopharyngeal carcinoma (NPC), which has the highest incidence in South China, is mainly treated by radiotherapy. However, the survival rate remains low. Angiogenesis is closely correlated with progress of NPC. Thus, the combination of anti-angiogenesis with radiation is an attractive strategy for NPC treatment. A heterogenic xenografted human NPC nude(More)
Targeted gene therapy needs to be implemented for future therapies to ensure efficient activity at the site of patient primary tumors or metastases without causing intolerable side-effects. One of the elements of gene therapy is vector, which includes viral and non-viral vector. In the present study, we constructed a novel non-viral targeted gene(More)
Identification of high-risk prognostic markers for stage II colorectal cancer (CRC) is currently a big challenge. CD133 is one of the most commonly used CRC stem cell markers. However, its specificity is controversial. Recent studies have demonstrated that the AC133 epitope of CD133, not the CD133 protein, is responsible for cancer stem cell identification.(More)
