DWCNTs have numerous industrial and biomedical applications and several studies reported that they could act as immunomodulator systems. The immune system is the first line of defence of the human body when exposed to particulate matter. In order to investigate DWCNTs’ role on innate immunity, we used THP-1 monocytic cells for the purpose of this study.We showed that DWCNTs were not cytotoxic until...
We investigated the effect of a 1800 MHz radiofrequency GSM signal combined with a known chemical mutagen (4-nitroquinoline-N-oxide: 4NQO) on human THP1 cells. Comet and γ-H2AX assays were used to assess DNA damage. No heating of the cell cultures was noted during exposure (2 h). The exposure of cells to electromagnetic fields with SARs of 2 to 16 W/kg did not increase the DNA damage induced by 4NQO,...
The intervention of pyruvate in glucose metabolism was investigated during hypoxic stress in tumour cell cultures having respiratory capacities under normoxic conditions. Results obtained with nuclear magnetic resonance (NMR) spectroscopy showed that, under normoxic conditions, rat glioma C6 and human hepatoma Hep G2 cell cultures metabolised [ 13 C 1 ]glucose into lactate, alanine,...
