Variable sizes of nanoparticles, ranging from nano to micro scale, are of toxicological interest. In the present study, the authors hypothesized that, in addition to the size, the shape of iron oxide (Fe2O3) nanoparticles is a major factor that contributes to particle cytotoxicity. Cytotoxicity to mouse macrophage cells (RAW 264.7) was investigated using 3(More)
Silver materials have been widely used in diverse fields. However, their toxicity and their mechanism, especially in different forms, have not been studied sufficiently. Thus, cytotoxicity, apoptosis, and interleukin-1beta (IL-1β) production were investigated using macrophage-like THP-1 cells in the presence of Ag microparticles (AgMPs, 2.7 µm), Ag(More)
Simvastatin exhibits anticancer activities, but its molecular mechanisms and radiosensitizing effects relative to p53 status remain unclear. In this study, we investigated whether the combination of simvastatin and ionizing radiation (IR) would enhance the antitumor effects of IR alone in HCT116 p53+/+ and p53‑/- colon cancer cells. Using colony formation(More)
Diabetes mellitus is a common chronic metabolic disease that is of increasing concern, because it frequently leads to complications such as cardiovascular diseases and cancer. Plants have been studied as a potential source for anti-diabetics to supplement dietary modifications, insulin, and other medications. The components of green tea polyphenols can be(More)
Protein phosphatase 2A (PP2A) is a ubiquitous multifunctional enzyme usually known as a tumor suppressor. Recent studies have reported that although inhibition of PP2A leads to acceleration of cell growth, it also induces damaged cells to pass through the cell cycle and renders them sensitive to radiotherapy. Here, we investigated the radiosensitizing(More)
Worldwide, colorectal cancer is the third most common cancer in men and the second most common in women. As conventional colorectal cancer therapies result in various side effects, there is a need for adjuvant therapy that can enhance the conventional therapies without complications. In this study, we investigated the anticancer effects of combined mixture(More)
