Reports from University of Adelaide Highlight Recent Findings in Cancer Therapy

June 26, 2014

By a News Reporter-Staff News Editor at Women's Health Weekly -- Fresh data on Oncology are presented in a new report. According to news originating from Adelaide, Australia, by NewsRx correspondents, research stated, "Here, we report a study on the biocompatibility, cell uptake and in vitro delivery of tumor necrosis factor-related apoptosis-inducing ligand (Apo2L/TRAIL) by new nano-carriers called anodic alumina nanotubes (AANTs) for potential cancer therapy. AANTs were electrochemically engineered by a unique pulse anodization process, which enables precise control of the nanotube geometry, and used here as nanocarriers for drug delivery."

Our news journalists obtained a quote from the research from the University of Adelaide, "In vitro cytotoxicity and cell uptake of AANTs was assessed using MDA-MB231-TXSA human breast cancer cells and mouse RAW 264.7 macrophage cells. AANTs exhibited excellent biocompatibility in both cell lines over a time course of five days even at a maximum concentration of AANTs of 100 mu g mL(-1). Transmission electron microscopy and fluorescence microscopy confirmed a significant uptake of AANTs by RAW 264.7 cells and breast cancer cells. AANTs loaded with the pro-apoptotic protein Apo2L/TRAIL showed exceptional loading capacity (104 +/- 14.4 mu g mg(-1) of AANTs) and demonstrated significant decrease in viability of MDA-MB231-TXSA cancer cells due to apoptosis induction."

According to the news editors, the research concluded: "These results demonstrate that AANTs are promising nano-carriers for drug delivery applications."
