In the present study, copper-based (25 - x)CaO - xCuO -10PO - 5BO - 60SiO (x = 2.5, 5, 7.5, 10 mol%) mesoporous bioactive glasses (MBGs) were synthesized using the sol-gel technique with cetyltrimethyl ammonium bromide as the structure-directing agent. The live-dead cell count and cytocompatibility of MBGs for J774A.1 murine macrophages have also been investigated for different concentrations of MBGs. The ionic dissolution profile for Ca, P and Si has been evaluated in the simulated body fluid. The effect of copper content as well as the ionic dissolution products on the up-regulation and down-regulation of TGIF-2, HDAC-4, Smurf-1, mir-30c and mir-130a genes for the murine model are investigated using reverse transcription-polymerase chain reaction. Silica and calcium release follows a similar trend as followed by gene up-regulation of TGIF-2, HDAC-4 and mir-30c genes. This indicates that silica and calcium release influence gene expression.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
