MicroRNAs (miRNAs) are small noncoding RNAs that have important roles in gene regulation. We have previously reported that activin receptor-like kinase 7 (ALK7) and its ligand, Nodal, induce apoptosis in human epithelial ovarian cancer cells. In this study, we examined the regulation of ALK7 by miRNAs and demonstrate that miR-376c targets ALK7. Ectopic(More)
Cancer cells are more susceptible to chemotherapeutic agent-induced apoptosis than their normal counterparts. Although it has been demonstrated that the increased sensitivity results from deregulation of oncoproteins during cancer development (Evan, G. I., and Vousden, K. H. (2001) Nature 411, 342-348; Green, D. R., and Evan, G. I. (2002) Cancer Cell 1,(More)
The radical scavenging activity of shikonin and acylshikonin derivatives was studied by using density functional theory. The hydrogen bond property of the studied structures was investigated using the atoms in molecules (AIM) theory. It turned out that the hydrogen bond is important for good radical scavenging activity. The hydrogen atom transfer for(More)
Glial cell line-derived neurotrophic factor (GDNF) is a type of neurotrophic factor with significant potential in treatment of Parkinson's disease. Combining gene targeting of animal somatic cells with nuclear transfer technique has provided a powerful method to produce transgenic animal mammary gland bioreactor. The aim of this study was to construct a(More)
The People's Republic of China has nearly the highest incidence of both diabetes mellitus (DM) and tuberculosis (TB) worldwide. DM increases the risk of TB by two to three times and adversely affects TB treatment outcomes. The increasing epidemic of DM in the People's Republic of China is due to decreased physical activity, unhealthy diet, and obesity. Over(More)
Numerous studies have demonstrated that the NDV-mediated gene therapy is a promising new approach for treatment of cancers. P53 plays a vital role in tumor suppression and surveillance. Therefore, we hypothesize that a recombinant NDV expressing P53 would be an ideal agent for the hepatoma therapy. In the essay, the human P53 gene was incorporated into the(More)
To investigate the cell-killing effect and its possible mechanism of rClone30-hDR5 in combination with TRAIL on human hepatic carcinoma (HCC) cell line, first of all, recombinant plasmid pee12.4-hDR5 was introduced into HepG2 cells by liposome transfection. After five rounds of screening by flow cytometry, HepG2 cells expressing high levels of DR5 on cell(More)
A high performance liquid chromatography coupled with photodiode-array detection method was developed for simultaneous determination of glycyrrhizin, paeoniflorin, benzoic acid, quercetin, ferulic acid, formononetin, liquiritin and isoliquiritigenin in the Chinese proprietary medicine "Xiao Yao Wan" (XYW). The analysis was performed by reverse phase(More)
BACKGROUND & OBJECTIVE Decreased expression of E-Cadherin correlated with many kinds of cancer, but inappropriate expression of N-cadherin has been reported in breast cancer recently, which has a more distinct and direct role in promoting cancer cell motility than E-cadherin. The aim of this study was to investigate the correlation between E-Cadherin and(More)
OBJECTIVE To analyze the causes of misdiagnosis in patients with familial nasal bleeding and to improve the level of diagnosis and treatment. METHOD The clinical characteristics of 7 families with nose blood were analyzed retrospectively and 2 typical cases were reported, including their treatment and misdiagnosis in consulting, out-patient and(More)
