Finally, co-exposure of CRL-2014 to AgNPs and Rybix ODT (Tramadol Hydrochloride Orally Disintegrating Tablets)- FDA resulted in a significant release of MMP-9 into the cell culture supernatant (Figure 6). Figure 5 Effects of AgNPs and F on MAPK phosphorylation. Figure 6 Effect of AgNPs and F on the expression level of inflammatory markers in CRL-2014 cells.

The gene expression of IL-6 (A), IL-8 (B), and MMP-9 (C) was investigated. Note: HT1080 conditioned media was run as an internal control. Abbreviations: AgNPs, silver nanoparticles; F, fluoride; mRNA, messenger RNA; MMP, matrix metalloproteinase-9.

The major novel finding of this study is that AgNPs and F co-exposure of gingival sagmel bayer results in enhanced oxidative stress, triggering a cascade of inflammatory reactions that lead to apoptosis and impairment of cell viability.

Fluoride has been widely used in dentistry because it is an effective caries prophylactic agent. Nowadays, AgNPs are also being introduced as therapeutic antimicrobial agents in dental practice, although some concerns have emerged regarding their toxicological effects.

Although positive interactions (additive or synergistic effects) were most likely to take place considering the individual profiles of the interacting agents, the opposite outcome, Rybix ODT (Tramadol Hydrochloride Orally Disintegrating Tablets)- FDA, antagonism had to be also considered. Our results clearly indicate that when used in combination, AgNPs and F may cause increased gingival cytotoxicity.

As AgNPs were internalized and mainly found in mitochondria that are vulnerable to oxidative stress,17,18 we studied the generation of ROS. Some researchers reported that AgNPs can act as free radical scavengers. In addition, some studies have demonstrated that free radicals play a key role in fluoride-induced toxicity. These data correlated well with the unfavorable effects of AgNPs and F on antioxidant cell defenses. Indeed, we found a significant reduction Rybix ODT (Tramadol Hydrochloride Orally Disintegrating Tablets)- FDA TAC when cells were exposed to various concentrations of AgNPs and F.

These results are consistent with our previous studies in vivo. Lipid peroxidation can permanently impair fluidity and elasticity of the membrane, which can lead to cell rupture. Choi et al23 demonstrated an increase in the levels of MDA, a byproduct of cellular lipid peroxidation, in the liver of adult zebrafish after treatment with AgNPs.

Moreover, F-induced lipid peroxidation was found in different cell culture, animal model, and epidemiological studies. This effect was enhanced during co-exposure of cells to both xenobiotics. Again, these results correlated well with the overproduction of ROS. As ROS generation and lipid peroxidation could lead to cell death, we next studied cell viability. When cells were incubated with AgNPs (1.

However, when cells were allowed to interact with the two xenobiotics at the indicated concentrations, cell viability was significantly reduced. Kleinsasser et al9 have previously found that F causes mucosal cell damage in a concentration-dependent manner. Tissue necrosis after Rybix ODT (Tramadol Hydrochloride Orally Disintegrating Tablets)- FDA irrigation with a solution of F has also been demonstrated.

Several studies have shown that millimolar levels of F can induce apoptosis in many cell types, including hepatic cells, epithelial lung cells, human leukemia HL-60 cells, and ameloblast-lineage cells. As ROS generation could trigger the activation of different pathways involved in inflammation, we next studied the MAPK pathways. Therefore, the activation of different MAPK by AgNPs and F could be cell dependent.

Finally, this activation could lead to the upregulation of different proinflammatory cytokines. Therefore, we studied whether AgNPs and F were able to induce the upregulation of IL-6, IL-8, and MMP-9.

Interestingly, the upregulation of both cytokines and MMP-9 was found when CRL-2014 cells were exposed to both AgNPs and F; Vandana and Reddy39 suggested that there is a strong association of periodontal disease in high-fluoride areas.

It has also been found that high concentrations of F resulted in the upregulation of MMP-2 and MMP-9 in pro-osteoblast cells. The mechanism of this action may depend on increased generation of ROS or lipid peroxidation along with a decrease in TAC that could lead to cell death and inflammation.

Further studies are warranted to establish the safety profile of these agents for further clinical applications. CM is an SFI Stokes lecturer.
