The effects of juice from Morinda citrifolia (noni) on gastric emptying, gastrointestinal transit, and plasma level of cholecystokinin (CCK) in rats were studied. Male rats were given noni by gavage at levels of 0.25, 1, or 4 ml/kg once per day for one or 7 days. The rats in the control group were given water, while the rats in the experimental group were(More)
The HNH motif was originally identified in the subfamily of HNH homing endonucleases, which initiate the process of the insertion of mobile genetic elements into specific sites. Several bacteria toxins, including colicin E7 (ColE7), also contain the 30 amino acid HNH motif in their nuclease domains. In this work, we found that the nuclease domain of ColE7(More)
Green fluorescent proteins (GFPs) are widely used in tracing transgene expression and have been known as convenient and efficient markers for plant transformation. However, sometimes researchers are still puzzled by the weak fluorescence since it makes the observation of GFP signals and confirmation of transgenic plants difficult. In this investigation, we(More)
Morinda citrifolia (noni) fruit juice is an increasingly popular health food with many reported benefits, such as antioxidant and immunomodulatory properties. Traditionally, noni fruit was used by Polynesians to combat fatigue. Also, clinical studies have revealed that noni juice consumption improves quality of life scores related to physical functioning(More)
In this paper, the effects of H2O2, a typical reactive oxygen species (ROS), on cell proliferation or death were examined using the human cervical carcinoma cell line HeLa and its MDR1-overexpressing subline, Hvr100-6, which was established by stepwise exposure to vinblastine. It was confirmed that the growth of HeLa cells was enhanced by H2O2 at relatively(More)
RATIONALE Cancer stem cell (CSC) theory has drawn much attention, with evidence supporting the contribution of stem cells to tumor initiation, relapse, and therapy resistance. OBJECTIVES To screen drugs that target CSCs to improve the current treatment outcome and overcome drug resistance in patients with lung cancer. METHODS We used publicly available(More)
Hepatocellular carcinoma (HCC) is an aggressive tumor with a poor prognosis. Currently, only sorafenib is approved by the FDA for advanced HCC treatment; therefore, there is an urgent need to discover candidate therapeutic drugs for HCC. We hypothesized that if a drug signature could reverse, at least in part, the gene expression signature of HCC, it might(More)
Drug resistance and tumor recurrence are major obstacles in treating lung cancer patients. Accumulating evidence considers lung cancer stem cells (CSCs) as the major contributor to these clinical challenges. Agents that can target lung CSCs could potentially provide a more effective treatment than traditional chemotherapy. Here, we utilized the(More)
Hepatocellular carcinoma (HCC) is a severe liver malignancy with few drug treatment options. In finding an effective treatment for HCC, screening drugs that are already FDA-approved will fast track the clinical trial and drug approval process. Connectivity Map (CMap), a large repository of chemical-induced gene expression profiles, provides the opportunity(More)
OBJECTIVE Fat-soluble vitamin (FSV) deficiencies are common complications in pediatric patients with chronic cholestasis. The aim of the present study was to evaluate the status of FSV deficiencies in patients under present practice and to test the effect of an oral, absorbable, fat-soluble vitamin formulation (OAFSV) in these patients. METHODS We(More)
