Abstract

Background

With the re-popularity of metal-on-metal (MoM) bearing in recent years, the cobalt toxicity has been a cause for concern in the total hip replacement surgery by both physicians and patients.

Methods

MG-63 cell line was cultured in vitro and incubated with cobalt (II) chloride (CoCl2) and/or with astaxanthin (ASX) for 24 h. MTT assay was conducted to evaluate the cell viability after cobalt exposure and ASX treatment. Fluorescence-activated cell sorting (FACS) analysis was performed to examine the reactive oxygen species (ROS) level. Quantitative real-time polymerase chain reaction (PCR) was adopted to determine the mRNA levels of related targets. And western blot analysis was used to examine the protein expressions. One-way ANOVA with posttest Newman-Keuls multiple comparisons was adopted to analysis all the obtained data.

Results

In the current study, ASX exhibited significant protective effect against the Co(II)-induced cytotoxicity in MG-63 cell line. We also found that ASX protected the cells against Co-induced apoptosis by regulating the expression of Bcl-2 family proteins. Besides, heme oxygenase 1 (HO-1) could be activated by Co exposure; ASX treatment significantly inhibited HO-1 activation, suppressing the oxidative stress induced by Co exposure. Moreover, c-Jun N-terminal Kinase (JNK) phosphorylation was shown to participate in the signaling pathway of the protective effect of ASX. However, knockdown of JNK expression by siRNA transfection or JNK inhibitor SP600125 treatment did not affect the protective effect of ASX against cobalt cytotoxicity in MG-63 cells.

Conclusions

ASX mitigated cobalt cytotoxicity in the MG-63 cells by modulating the oxidative stress. And ASX could be a promising therapy against cobalt toxicity in the hip articulation surgery.

Background

Hip arthroplasty is the most commonly used therapy to treat joint failure caused by osteoarthritis [1]. Metal-on-metal (MoM) bearings were originally reintroduced over the last 20 years [2] because of their lower volumetric wear rates in comparison to conventional metal-on-polyethylene bearings [3, 4], especially in young and active patients [5]. However, with a MoM hip prosthesis, continuous motion could cause the generation of metal particles and ions [69], mainly cobalt (Co) and chromium (Cr), which lead to systemic or local toxicity such as neuro-ocular toxicity, cardiotoxicity, bone loss, tissue damage, metal hypersensitivity and chromosomal changes [10, 11]. Significant increase of Co ion was found in the whole blood or serum of MoM-implanted patients, compared with preoperative values; and the elevated Co level was connected to the head size of the implanted MoM bearings [8, 12, 13]. It’s well known that Co of high concentration is toxic [14]; nevertheless, the potential underlying mechanism might be involved with enhanced tissue oxidative stress [15], triggered intrinsic apoptosis [16, 17], which impact osteoclast activity though inducing CSF (colony stimulating factor) and RANKL (Receptor Activator for Nuclear Factor-κB Ligand), as well as cytokines secretion of microphage cells (TNF-α, IL-6) [1820].

Astaxanthin (ASX) is a dark red pigment and a dietary carotenoid found in algae, crustaceans, and fish [21, 22]. Despite that it is a primary component of coloration, ASX is a protective agent in marine plants and fish. For example, in fish, dietary ASX could alter liver function and improve defenses against oxidative stress. It has been reported that ASX is 5 to 15 times more potent antioxidant than β-carotene and lutein, which share similar structure with ASX [23]. The mechanism underlying the anti-oxidative effect of ASX included blocking ROS generation and dose-dependently inhibiting apoptosis through a mitochondrial signaling pathway [24]. Besides, some studies also reported that ASX has other potent biological activity such as anti-inflammation, anticancer and immuno-modulation [25]. Barim-Oz et al. reported that ASX is a more potent antioxidant than vitamin C, vitamin A and beta-carotene [26]. Fang et al. also demonstrated that ASX protects against early burn-wound progression in rats by attenuating oxidative stress-induced inflammation and mitochondria-related apoptosis [27]. Kim et al. proved that ASX inhibits inflammation and fibrosis in the liver and adipose tissue of mouse models of diet-induced obesity and nonalcoholic steatohepatitis [28]. Lin et al. found that ASX stimulates immune responses by enhancing IFN-gamma and IL-2 Secretion in primary cultured lymphocytes in vitro and ex vivo [29].

Previous results have demonstrated that Co (II) ions could induce oxidative stress in MG-63 cells, an osteosarcoma cell line [30]. To explore the potential protective effect of antioxidant ASX against oxidative stress in MG-63 cells, the current study examined cell viability, ROS level, apoptosis and secretion of cytokines after Co(II) and ASX treatment.

Methods

Materials

Cobalt (II) chloride (CoCl2) was purchased from Sigma-Aldrich (St. Louis, MO; #60818). Astaxanthin was purchased from Sigma-Aldrich (St. Louis, MO; #41659). Dimethyl sulfoxide (DMSO) was obtained from Sangon Biotech (Shanghai, China; # A100231).

Cell culture and treatment

MG-63 was purchased from ATCC (American Type Culture Collection), the cells were cultured in ATCC-formulated Eagle’s Minimum Essential Medium (Hyclone, USA) supplemented with 10% fetal bovine serum (Hyclone, USA) at 37 °C in 5% CO2 and subcultured every 2 to 3 days. In 80% conjugation, the cells were starved free of FBS overnight and treated with cobalt (II) of different concentrations (10, 50, 100, 200, 400 μM) for 24 h. For astaxanthin treatment, the concentrations include 1, 5, 10, 20 nM, and the time period was also 24 h.

Cell viability assay

In vitro MTT (Thiazolyl blue tetrazolium bromide) cell proliferation and cytotoxicity assay was performed. Cells were cultured at 5000 per well in 96-well tissue culture plates. To assess cell viability, cobalt or AST were added after plating. At the end of the culture period, 20 μL of MTT solution (CellTiter 96 Aqueous One Solution Cell Proliferation Assay; Beyotime Biotechnology, China) was added, the cells were incubated for a further 2 h, and the absorbance was measured at 490 nm using an ELISA plate reader (Beyotime Biotechnology, China). Because the absorbance at 490 nm is linear with the cell concentration to a certain degree in the MTT test. The cell viability was calculated using OD490 (optical density) through the following equation:
$$ \mathrm{the}\ \mathrm{cell}\ \mathrm{viability}\ \mathrm{of}\ \mathrm{X}\ \left(\%\right)=\frac{\mathrm{ODx}}{\mathrm{Average}\ \mathrm{OD}\left(\mathrm{control}\ \mathrm{group}\right)}\times 100. $$

Measurement of intracellular ROS

Fluorescent probe DCFH-DA was used to determine the changes of the intracellular generation of ROS. After treatments, cells were rinsed three times with PBS, and incubated with 5 μM DCFH-DA at 37 °C for 30 min. The fluorescence intensity was examined at 525 nm using Microplate Reader (Thermo Scientific, USA).

Quantitative real-time polymerase chain reaction (PCR).

The total RNA from the cells was isolated using the TRIzol reagent (Invitrogen), and the cDNA was synthesized following the manufacturer’s protocols using 1 μg RNA (Prime ScriptTM RT reagent Kit, Takara). qRT-PCR was performed using a standard SYBR-green PCR kit (Takara), and the gene-specific PCR amplification was performed using the Applied Biosystems 7300 Sequence Detection system (Applied Biosystems, USA). The qRT-PCR reactions, including the no-template controls, were performed in triplicate. For each sample, the data were normalized to the housekeeping gene glyceraldehyde 3-phosphate dehydrogenase (GAPDH). The designed primers in this study were:

TNF-α forward primer, 5′- GAGGCCAAGCCCTGGT ATG-3′,

and TNF-α reverse primer, 5′-GAGGCCAAGCCCTGGTATG -3′;

GAPDH forward primer, 5′- ACAACTTTGGTATCGTGGAAGG-3′;

and GAPDH reverse primer, 5′- GCCATCACGCCACAGTTTC-3′;

NF-κB forward primer, 5′- GCTTAGGAGGGAGAGCCCAC -3′;

and NF-κB reverse primer, 5′- TAGGACGTTGTGTTCCTTCCG -3′;

HO-1 forward primer, 5′- ACAACTTTGGTATCGTGGAAGG-3′;

and HO-1 reverse primer, 5′- GCCATCACGCCACAGTTTC-3′.

Analysis was performed using the comparative Ct value method. For each sample, the data were normalized to the housekeeping gene GAPDH.

Western blot analysis

The cells were lysed in RIPA lysis buffer (Beyotime). The lysates were centrifuged at 12,000 rpm and 4 °C for 10 min. The same amounts of protein were separated using 10–15% odium dodecyl sulfate-polyacrylamide gel electrophoresis (the exact concentration was determined by the molecular weight of the detected proteins) and transferred to nitrocellulose membranes (Millipore). For immunodetection, the membranes were incubated with specific antibodies and the following antibodies were used: anti-Bcl2 (Abcam, ab7973), anti-BAX (Abcam, ab7977), anti-caspase 3(CST, 9662S), anti-HO-1(CST, 5853S), anti-ERK (Abcam, ab17942), anti-p-ERK(CST, 5683S), anti-JNK(CST, 9258S), anti-p-JNK(CST, 9255S), anti-AKT(CST, 4691S), anti-p-AKT(CST, 4060S), anti-P38(CST, 9212S), anti-p-P38(CST, 4511S). The immunoblots were developed using horseradish peroxidase (HRP)-coupled anti-rabbit secondary antibodies (ProteinTech Group) and then detected with enhanced chemiluminescence (Pierce Biotechnology). The GAPDH protein was used as a control.

Cell apoptosis analysis by FACS

The cells were treated with Co2+ or (and) ASX, after incubation for 24 h, the cells were harvested using trypsin without EDTA, then the cells were washed twice with ice-cold phosphate buffered saline (PBS) containing 2% FBS. The cells were then centrifuged, resuspended in 195 μL binding buffer on ice, add 5 μL FITC stained Annexin V, incubate 30 min for 15 min at 4 °C, and just before the analyzed, 5 μL PI was added. The data acquisition and analysis were performed using a FACS cytometer (FACS, CA, USA). A total of 1 × 105 cells were scanned in each analysis. Each experiment was repeated at least three times.

Statistical analysis

Data were compared using one-way ANOVA with posttest Newman-Keuls multiple comparison. P value of or less than 0.05 was considered statistically significant. The data are expressed as mean values ± SD/SEM and statistics were calculated with Graphpad Prism Software.

Results

Astaxanthin significantly ameliorated the cytotoxicity and apoptosis induced by cobalt treatment

First, we observed the cytotoxic effect of Co2+ (10, 50, 100, 200, 400 μM) treatment (24 h) in the viability of human MG-63 cells. As shown in Fig. 1, Co2+ treatment significantly reduced the cell viability as the concentration increased from 50 μM to 400 μM (Fig. 1a, Additional file 1: Table S1). Especially, at the concentration of 200 μM, Co2+ decreased the cell viability by about 50% (Fig. 1a); hence we chose 200 μM as the designated concentration in our subsequent experiment. Results showed that ASX treatment significantly enhanced the MG-63 cell viability (Additional file 2: Figure S1A). Compared to Co2+-treated group, the Co2+-exposed MG-63 cells treated by ASX exhibited a significant increase in the cell viability, as the concentration of ASX increased from 1 nM to 20 nM (Fig. 1b, Additional file 1: Table S2). To investigate the mechanism underlying the protective effect of ASX, we examined the apoptosis after Co2+ exposure and ASX treatment. It was found by FACS assay that ASX treatment significantly inhibited the MG-63 cell apoptosis induced by Co2+ exposure (Fig. 1c). Then we examined the expression of apoptosis-related target to explore the mechanism underlying the protective effect of ASX against the cell apoptosis. Results showed that, exposure to Co2+ for 24 h induced a significantly increased expression of Caspase-3 and Bax, a marked decreased expression of Bcl-2, in MG-63 cells; ASX pretreatment for 24 h remarkably attenuated Co2+-induced activation of apoptotic proteins (Fig. 1d).

Astaxanthin attenuates the oxidative stress caused by cobalt exposure

Cobalt could promote cell apoptosis though stimulating oxidative stress and downstream mediators [3133]. Therefore, we measured the intracellular ROS level using the fluorescent probe 2′,7′-dichlorofluorescin diacetate (DCFH/DA). It was shown that Co2+ significantly increased the DCF fluorescence intensity, while ASX markedly reduced the ROS level as the concentration rises from 1 nM to 20 nM (Additional file 2: Figure S1A). HO-1 is a generalized marker enzyme of antioxidant [30, 33]. It was found that ASX treatment for 24 h significantly decreased the expression of HO-1 (Fig. 2a). JNK pathway was reported by many to be related in the HO-1 induction in the oxidative stress [3437]. We also observed a significant inhibition of JNK phosphorylation by ASX treatment. As oxidative stress plays an important role in cobalt-induced cytotoxicity and cell apoptosis, the protective effect of ASX might be attributed to its antioxidant capacity. Besides, we also observed an involvement of p38, ERK and AKT pathway in the protective effect of ASX against cobalt cytotoxicity (Additional file 2: Figure S1B).
Fig. 2

Protection of astaxanthin against cobalt cytotoxicity was related to HO-1 expression and JNK phosphorylation. a Compared to control, Co2+exposure significantly elevated the expression of HO-1, which was reduced by ASX pretreatment as the concentration rises. (1, vehicle-treated MG-63 cells; 2, Co2+-exposed cells; 3, Co2+-exposed cells treated by ASX (1 nM); 4, Co2+-exposed cells treated by ASX (5 nM); 5, Co2+-exposed cells treated by ASX (10 nM); 6, Co2+-exposed cells treated by ASX (20 nM); **P < 0.01 vs 1; ## P < 0.01 vs 2) b) Compared to Co2+-exposed group, the ASX pretreatment significantly inhibited the phosphorylation of JNK. (**P < 0.05 vs Co)

Downregulation of JNK did not affect the protective effect of astaxanthin against cobalt cytotoxicity

Then we examined whether downregulation of JNK by siRNA or an inhibitor (SP600125) could affect the protective effect of ASX against cobalt cytotoxicity in MG-63 cells. At 24 h after siRNA interfering, qPCR analysis showed that the mRNA levels of TNF-α, NF-κB and HO-1 were significantly suppressed by ASX treatment (Fig. 3a). In addtion, downregulation of JNK did not significantly alter the mRNA levels of TNF-α and HO-1 compared to ASX-treated group; however, JNK suppression significantly enhanced the NF-κB mRNA level (Fig. 3a). Subsequent western blot analysis demonstrated that JNK downregulation did not alter the expression of TNF-α, NF-κB and HO-1 compared to ASX-treated group (Fig. 3b).
Fig. 3

Downregulation of JNK did not significantly affect the protection of ASX against cobalt cytotoxicity. a qRT-PCR analysis showed that: ASX pretreatment markedly decreased the mRNA levels of TNF-α, NF-κB and HO-1, and downregulation of JNK by siRNA interfering or the inhibitor SP600125 did not significantly abolish the protection of ASX pretreatment. (**P < 0.01 vs Con; ## P < 0.01 vs Co; §§ P < 0.01 vs Co + ASX) b) Western blot assay showed that ASX pretreatment markedly decreased the expression of TNF-α, NF-κB and HO-1, and downregulation of JNK by siRNA interfering or the inhibitor SP600125 did not significantly abolish the protection of ASX pretreatment. (**P < 0.01 vs Con; ## P < 0.01 vs Co; §§ P < 0.01 vs Co + ASX)

Discussion

The current study found that a dietary supplement ASX might have a protective effect against cobalt toxicity in MG-63 cells, implying a possible application of ASX in patients who underwent metal-metal hip articulation.

Cobalt is a mineral which is required as dietary supplements in trace amount. But it displays toxic effects when present at high concentration. Groups of patients implanted with hip devices of MoM bearing surface have been shown to develop an accelerated inflammatory reaction frequently associated with tissue necrosis and cellular toxicity; because of tribocorrosion, metal-based implants release wear debris. And the particles released from the implants contain Co2+ [38]. It has been reported that Co2+ could induce monocyte/macrophages to release bone absorption factor and cause bone around the prosthesis dissolved [39], 100 μM Co2+ resulted in significant decreases in cell viability accompanied by a significant increase in apoptosis on primary human lymphocytes, Co2+ also have a cytotoxic effect on human MG-63 osteoblasts cell [38], our results confirmed that Co2+ is toxic to MG-63 cells.

ASX is a carotenoid that possesses strong antioxidant activity [40]. It was reported that the parameters of ASX were dose dependent if administrated intravenously, but dose independent if taken orally, due to primary metabolizm by hepatic cytochrome P450 [41]. Besides, diet could elevate the bioavailability of ASX significantly [42]. Recent studies reported that ASX could alleviate oxidative stress in vitro and vivo. In human vascular endothelial cells, it would attenuate glucose fluctuation-caused oxidative stress and cell apoptosis [43]; in vivo, ASX was showed to significantly ameliorate hepatic ischemia reperfusion (IR) injury by reducing ROS level and inhibiting MAPK pathway [44]; the underlying mechanism was partly involved with the downregulation of NF-κB activity [45, 46]. The present study demonstrated that ASX treatment markedly inhibited the cobalt toxicity in MG-63 cells, which could be partially attributed to oxidative stress pathway.

Our research explored the antidote effect of ASX against Co toxicity in the way of oxidative stress and related pathways, such as JNK, HO-1, TNF-α, NF-κB etc. Extensive reports showed that ROS was closely related to JNK, P38 and ERKs pathway [47, 48]. These findings are consistent with our results. Mitani et al. [49] demonstrated that induction of HO-1 expression could inhibit inflammatory reaction through decreasing oxidative stress in mice intestine. Preventing JNK, P38 activation and mitochondrial pathway could ameliorate high glucose-induced PC12 cell apoptosis [50]. All the evidences highlighted the role of oxidative stress in the mechanism by which ASX ameliorated cobalt toxicity in MG-63 cells.

Conclusion

In conclusion, our results show that increase in cobalt (II) concentration could induce significant apoptosis in MG-63 cells, which could be inhibited by ASX treatment. The underlying mechanism was probably involved with modulation in oxidative stress. Whether ASX can be applied in clinical to reduce the MoM artificial hip caused side-effect needs further in-vivo study.
