Effect of aspirin on cell growth of human MG-63 osteosarcoma life Luna-Bertos, María Elvira de Ramos-Torrecillas, Javier García-Martínez, Olga Díaz-Rodríguez, Lourdes Ruiz-Rodríguez, Concepción Nonsteroidal antiinflammatory drugs Human osteoblasts Diclofenac Bone Acetaminophen Ibuprofen Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used in bone tissue repair treatment for their pharmacological action. The objective of this study was to determine the effect of aspirin, on osteoblast growth, using MG63 cell line as osteoblast model. MTT spectrophotometry results showed that 20, 100, and 1000 μM aspirin doses have an inhibitory effect on growth. Cell cycle analysis revealed that aspirin doses of 100 and 1000 μM arrest the cell cycle in phase GO/G1. Parallel apoptosis/necrosis studies showed no changes in comparison to control cells after treatment with 1 or 10 μM aspirin but a significantly increased percentage of cells in apoptosis at doses of 20, 100, and 1000 μM. We highlight that treatment of osteoblast-like cells with 1000 μM aspirin increased not only the percentage of cells in apoptosis but also the percentage of necrotic cells, which was not observed in aspirin treatments at lower doses. 2014-05-30T07:51:31Z 2014-05-30T07:51:31Z 2012 journal article Luna-Bertos, E.; et al.
