| Abstract |
BACKGROUND: Hwangryun-haedok-tang (HRT) is traditional herbal medicine used to treat inflammatory-related diseases in Asia. However, its effect on osteoclastogenesis and bone loss is still unknown. In this study, we evaluated the effect of HRT and its fermented product (fHRT) on the receptor activator for the nuclear factor-kappaB ligand-induced osteoclastogenesis using murine bone marrow-derived macrophages and postmenopausal bone loss using an ovariectomy (OVX) rat model. METHODS: Tartrate resistant acid phosphatase (TRAP) staining was employed to evaluate osteoclast formation. mRNA level of transcription factor and protein levels of signaling molecules were determined by real-time quantitative polymerase chain reaction and Western blot analysis, respectively. Effect of HRT or fHRT on OVX-induced bone loss was evaluated using OVX rats orally administered HRT, or fHRT with 300 mg/kg for 12 weeks. Micro-CT analysis of femora was performed to analyze bone parameter. RESULTS: HRT or fHRT treatment significantly decreased TRAP activity and the number of TRAP positive multinuclear cells on osteoclastogenesis. Interestingly, these inhibitory effects of HRT were enhanced by fermentation. Furthermore, fHRT significantly inhibited mRNA and protein expression of nuclear factor of activated T cells cytoplasmic 1, which leads to down-regulation of NFATc1-regulated mRNA expressions such as TRAP, the d2 isoform of vacuolar ATPase V(0) domain, and cathepsin K. Administration of fHRT significantly inhibited the decrease of bone mineral density, and improved bone parameter of femora more than that of HRT and vehicle in OVX rats. CONCLUSIONS: This study demonstrated that lactic bacterial fermentation fortifies the inhibitory effect of HRT on osteoclastogenesis and bone loss. These results suggest that fermented HRT might have the beneficial potential on osteoporosis by inhibiting osteoclastogenesis. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 24 May 2013.
All research outputs
#20,194,150
of 22,711,242 outputs
Outputs from BMC Complementary Medicine and Therapies
#2,967
of 3,619 outputs
Outputs of similar age
#170,235
of 195,184 outputs
Outputs of similar age from BMC Complementary Medicine and Therapies
#68
of 69 outputs
Altmetric has tracked 22,711,242 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,619 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.5. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 195,184 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 69 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
