TRAIL and Celastrol Combinational Treatment Suppresses Proliferation, Migration, and Invasion of Human Glioblastoma Cells via Targeting Wnt/β-catenin Signaling Pathway.

Objective: To investigate the mechanistic basis for the anti-proliferation and anti-invasion effect of tumor necrosis factor-related apoptosis-induced ligand (TRAIL) and celastrol combination treatment (TCCT) in glioblastoma cells.

Methods: Cell counting kit-8 was used to detect the effects of different concentrations of celastrol (0-16 µmol/L) and TRAIL (0-500 ng/mL) on the cell viability of glioblastoma cells. U87 cells were randomly divided into 4 groups, namely control, TRAIL (TRAIL 100 ng/mL), Cel (celastrol 0.

Enhanced anti-tumor efficacy of 5-aminolevulinic acid-gold nanoparticles-mediated photodynamic therapy in cutaneous squamous cell carcinoma cells.

The objective of this study was to investigate whether the conjugation of gold nanoparticles (GNPs) to 5-aminolevulinic acid (5-ALA) could enhance the anti-tumor efficiency of photodynamic therapy (PDT) in epidermoid carcinoma cells. The mRNA and protein expression levels were determined by quantitative real-time PCR and western blot, respectively. Cell viability, apoptosis, invasion, and migration were determined by MTT assay, flow cytometry, transwell invasion assay, and migration assay, respectively.

[Efficiency of Aerobic Co-composting of Urban Sludge and Chinese Medicinal Herbal Residues].

With Chinese medicinal herbal residues and municipal sludge as raw materials for co-composting experiment, the effect of the material ratio and addition time of Chinese medicinal herbal residues on the composting efficiency were investigated, including the change of the temperature, organic matter, ammonia nitrogen, and activity of protease. The best composting conditions were determined based on the results. The experimental results showed that the temperature of the pile was raised in the presence of 60 g Chinese medicinal herbal residues as carbon source and 300 g municipal sludge, the ammonia volatilization was reduced and the activity of protease was improved.

[Chemical constituents from medical and edible plants of Rosa roxburghii].

Rosa roxburghii, a kind of the medical and edible plants belonging to the Rosaceae family, is widely distributed in the southwest districts of China, especially Guizhou province. Now, by reason of the extensive bioactivities, the plant is widely used in the field of food, health product, drug, and so on. In the course of our continuing search for the bioactive constituents, thirteen compounds were isolated from R.

nm23 gene polymorphisms are associated with survival of patients with epithelial ovarian cancer but not with susceptibility to disease.

Objective: nm23, a tumor metastasis suppressor gene, has been linked to protection against tumorigenesis and tumor metastasis. This study evaluated whether genetic variants in the nm23 gene were associated with susceptibility to epithelial ovarian cancer (EOC) or the clinical outcome of patients.

Methods: A case-control study was performed with 302 patients with epithelial ovarian cancer and 302 control women.

Association of vascular endothelial growth factor gene polymorphisms with susceptibility to epithelial ovarian cancer.

Background: Vascular endothelial growth factor (VEGF) is a major angiogenic factor involved in a number of pathological processes, including neovascularization, a crucial step in the development of solid malignancies. The aim of this study was to investigate the association of polymorphisms in the VEGF gene with susceptibility to epithelial ovarian cancer (EOC).

Methods: This case-control study included 303 EOC patients and 303 healthy controls.
