Suberoylanilide Hydroxamic Acid, an Inhibitor of Histone Deacetylase, Induces Apoptosis in Rheumatoid Arthritis Fibroblast-Like Synoviocytes.

Here, we explored the effects of suberoylanilide hydroxamic acid (SAHA) on the viability and apoptosis of rheumatoid arthritis of fibroblast-like synoviocytes (rheumatoid arthritis (RA) fibroblast-like synoviocytes (FLS)). FLS obtained from RA patients were treated with SAHA. SAHA significantly inhibited the viability of RA FLS in a concentration-dependent manner up to 5 μM.

[Effects of arsenic trioxide on the autoimmunity and survival time in BXSB lupus mice].

Objective: To investigate the effect of arsenic trioxide (ATO) on the autoimmunity and survival time in BXSB lupus mice.

Methods: The model BXSB lupus mice were randomly divided into two groups equally, the ATO treated group and the control group, 17 in each group. Mice in the ATO group were given intraperitoneal injection of ATO at the daily dose of 0.
