Inhibitory effect of sodium houttuyfonate on synovial proliferation in vitro in cells from a patient with rheumatoid arthritis

Abstract

The aim of the present study was to investigate the inhibitory effect of sodium houttuyfonate (SH) on synovial cell proliferation in vitro. Primary cells were obtained from the synovial tissue of a patient with rheumatoid arthritis (RA). The cells were divided into five treatment groups as follows: the control group (group 1), 25 μg/ml SH-treated group (group 2), 50 μg/ml SH-treated group (group 3), 100 μg/ml SH-treated group (group 4) and the 200 μg/ml SH-treated group (group 5). Following seven days of treatment, the proliferation rate of the synovial cells was then detected using an MTT assay. The expression level of proliferative synovial cells markedly decreased in the SH-treated groups in a dose-dependent manner compared with the control group. In conclusion, the present study demonstrated that SH was able to inhibit the proliferation of synovial cells obtained from a patient with RA. These results provide a potential theoretical basis for the development of a safe and effective treatment against RA in the future.

Tripterygium Ingredients for Pathogenicity Cells in Rheumatoid Arthritis

“…Many studies showed the Tripterygium ingredients have the properties to promote FLS apoptosis and cell cycle arrest and inhibit FLS autophagy ( Xu, 2013 ; Xu et al., 2013 ; Lei et al., 2015 ; Su et al., 2017 ; Wong et al., 2019 ). It may be relevant to the increased expression of Bax/Bcl-2, Caspase-3, Caspase-9, and regulating by Ca2+/calmodulin-dependent protein kinases beta (CaMKK)-AMPK-mTOR signaling pathway.…”

Protective effect of taraxasterol against rheumatoid arthritis by the modulation of inflammatory responses in mice

“…joints and is known to have the following pathological characteristics: Auto-antibody production, synovial cell hyperplasia, inflammatory cell infiltration (such as neutrophile granulocytes and macrophages), pannus production and destruction of bones and cartilage, which finally lead to the destruction and lack of function of a whole joint (9). According to official statistics, rheumatoid arthritis is an important cause of productivity loss and extremity disability in China, with a morbidity rate of 0.32-0.36% (10).…”

The therapeutic potential of Houttuynia cordata: A current review

“…Primary cells of synovial tissue were collected from RA patients, cultured and subjected to SH treatment. Interestingly, post treatment, synovial proliferation in SH treatment groups were markedly lower than the control group (P < 0.05) in a dose dependent manner, with 200 μg/mL SH showing the highest inhibitory effects ( Li et al., 2014 ).…”
