| 英文摘要 | Due to similar aerodynamic and micro-nano sized properties between airborne particles and synthetic nano particles, a large number of studies have been conducted using carbon-based particles, such as carbon black (CB), carbon nanotubes and graphite, in order to achieve deeper understandings of their adverse effects on human health. It has been reported that particulate matters can aggravate morbidity of patients suffering from bone and joint diseases, e.g. arthritis. However, the molecular mechanism is still elusive thus far. Under this context, we employed two cell lines of osteoblasts, MC3T3-E1 and MG-63, upon exposure to 4 different CB samples with differential physicochemical properties in research of mechanistic insights. Our results indicated that the carbon/oxygen ratio differed in these 4 CB materials showing the order: SB4A < Printex U < C1864 < C824455. In stark contrast, their cytotoxicity and capacity to trigger reactive oxygen species (ROS) in MC3T3-E1 and MG-63 cells closely correlated to oxygen content, revealing the reverse order: SB4A < Printex U < C1864 < C824455. It would be reasonable to speculate that ROS production was a predominant cause of CB cytotoxicity, which strongly relied on the oxygen content of CB. Our study further manifested that all CB samples even at low concentrations significantly inhibited osteoblast differentiation, as reflected by remarkably reduced activity of alkaline phosphatase (ALP) and compromised expression of the differentiation-related genes. And the inhibition on osteoblast differentiation also closely correlated to oxygen content of CB samples. Taken together, our combined data recognized oxygen-associated toxicity towards osteoblasts for CBs. More importantly, we uncovered a new adverse effect of CB exposure: suppression on osteoblast differentiation, which has been overlooked in the past. |
