Drug resistance frequently develops in tumors during chemotherapy. Therefore, to improve the clinical outcome, more effective and tolerable combination treatment strategies are needed. Here, we show that isochaihulactone (K8) enhanced paclitaxel-induced apoptotic death in human lung cancer cells, and the enhancing effect was related to increased(More)
Recombinant adenovirus-associated vector serotype 2 (rAAV2) is one of the most promising gene transfer vectors due to its advantage of causing non-pathogenic infection, low immunogenicity, and long-term gene expression in human clinical trials. Human interleukin 15 (hIL15) has been implicated in modulation of antitumor activity of lymphokine-activated(More)
Epigenetic alteration of DNA methylation plays an important role in the regulation of gene expression associated with chemosensitivity of human hepatocellular (HCC) carcinoma cells. With the aim of improving the chemotherapeutic efficacy for HCC, the effect of the naturally occurring compound n-butylidenephthalide (BP), which is isolated from a chloroform(More)
Chronic inflammatory processes have been increasingly shown to be involved in the pathogenesis of diabetes and diabetic nephropathy. Recently, we demonstrated that a lectin-like domain of thrombomodulin (THBD), which is known as THBD domain 1 (THBDD1) and which acts independently of protein C activation, neutralised an inflammatory response in a mouse model(More)
Rana catesbeiana ribonuclease (RC-RNase) possesses tumor-specific cytotoxicity, which can be synergized by IFN-gamma. However, it is unclear how RC-RNase and RC-RNase/IFN-gamma induce cell death. In this study, we use substrate cleavage assays to systematically investigate RC-RNase- and RC-RNase/IFN-gamma-induced caspase activation in HL-60, MCF-7, and(More)
Aristolochic acid (AA) is a component of Chinese medicinal herbs, including asarum and aristolochia and has been used in Traditional Chinese Medicine for a long time. Recent studies found that AA has a cytotoxic effect resulting in nephropathy. These studies indicated that AA‑induced cytotoxicity is associated with increases in oxidative stress and(More)
Glioblastoma multiforme (GBM) is the most common and lethal type of primary brain tumor. Despite recent therapeutic advances in other cancers, the treatment of GBM remains ineffective and essentially palliative. The current focus lies in the finding of components that activate the AMP-activated protein kinase (AMPK), one key enzyme thought to be activated(More)
Rana catesbeiana ribonuclease (RC-RNase) is a cytotoxic and antitumor RNase isolated from the oocyte yolk granules of the bullfrog R. catesbeiana. Our previous studies have shown that RC-RNase possesses antitumor activity by activating proapoptotic caspases. Here, we demonstrate that RC-RNase also possesses antiviral activity. By using cell viability and(More)
Human interleukin-15 (hIL15) has anti-tumor activities, but it is not convenient for tumor treatment because of its short half-life. A gene therapy for mouse lung cancer using an adenovirus vector expressing IL15 has been reported. However, adenovirus vector-mediated gene therapy can provoke cellular toxicity and inflammatory reactions. The recombinant(More)
AIM To investigate the role of hTERT gene expression and AP-2alpha in n-butylidenephthalide (n-BP)-induced apoptosis in A549 lung cancer cells. METHODS Viability of A549 cells was measured by MTT assay. Protein expression was determined by Western blot. Telomerase activity was measured using the modified telomere repeat amplification protocol (TRAP)(More)
