In this study, the effects of 136 naturally occurring products, which have been reported to play important roles in modification of Cytochrome P450 (CYP450) activities, on the uptake of estrone-3-sulfate (E3S), a typical OATP1B1 substrate, were evaluated using human embryonic kidney 293 cells stably expressing OATP1B1. At a concentration of 100 μM, 42… (More)
The pathogenesis of glioma remains largely unknown now. It has been suggested that the X-ray cross-complementing group 1 (XRCC1) gene may influence the capacity to repair DNA damage leading to an increased gliomas susceptibility. This study aimed to evaluate the relationship between XRCC1 polymorphisms and glioma risk. Genotypes were assessed in 368 Chinese… (More)
Oxidative stress and glutathione (GSH) depletion are implicated in mycocystin hepatotoxicity. To investigate the role of nuclear factor erythroid 2-related factor 2 (Nrf2) in microcystin-induced liver injury, Nrf2-null, wild-type, and Keap1-hepatocyte knockout (Keap1-HKO) mice were treated with microcystin (50 μg/kg, i.p.). Blood and liver samples were… (More)
BACKGROUND Glioblastoma is the most common type of primary brain tumors. Cisplatin is a commonly used chemotherapeutic agent for Glioblastoma patients. Despite a consistent rate of initial responses, cisplatin treatment often develops chemoresistance, leading to therapeutic failure. Cellular resistance to cisplatin is of great concern and understanding the… (More)
Dysregulated long noncoding RNAs (lncRNAs) have been found in human diseases, especially in cancer. Emerging evidence indicates that dysregulated lncRNAs are implicated in tumorigenesis and cancer progression. LncRNA AB073614 characterized as a new candidate lncRNA promotes the development of ovarian cancer. However, the role of lncRNA AB073614 in human… (More)
A sensitive biosensor: A strategy for the intracellular imaging of Cu(2+) ions has been developed by integrating a recognition molecule, N-(2-aminoethyl)-N,N,N'tris(pyridin-2-ylmethyl)ethane-1,2-diamine (AE-TPEA), into a hybrid system composed of carbon and CdSe/ZnS quantum dots.
Cancer cells that develop resistance to cisplatin (DDP) are a major clinical obstacle to the successful treatment of cancer, including non-small cell lung cancer (NSCLC). Recent studies have implicated dysregulation of microRNAs (miRNAs) function in chemoresistance. Here, we explored the role of let-7c in the acquisition of DDP-resistant phenotype in A549… (More)
AIM To investigate the effect of quercetin on organic anion transporting polypeptide 1B1 (OATP1B1) activities in vitro and on the pharmacokinetics of pravastatin, a typical substrate for OATP1B1 in healthy Chinese-Han male subjects. METHODS Using human embryonic kidney 293 (HEK293) cells stably expressing OATP1B1, we observed the effect of quercetin on… (More)
Furosemide is a diuretic drug, but its reactive intermediates lead to acute liver injury in mice. Given the essential role of Nrf2 as a cellular defense regulator, we investigated whether Nrf2 would protect against furosemide-induced liver injury using the Nrf2 "gene-dose response" mouse model (Nrf2-null with Nrf2 knock-out, wild-type with normal expression… (More)
An efficient strategy for selective fluorescent detection of Cu(2+) was developed based on the carbon quantum dots (CQDs) nanoconjugated with a specific organic molecule, amino TPEA, and further applied to intracellular sensing and imaging of Cu(2+) as a consequence of the fluorescence properties and the established low cytotoxicity of CQDs.
