Anti-proliferation and anti-migration effects of an aqueous extract of Cinnamomi ramulus on MH7A rheumatoid arthritis-derived fibroblast-like synoviocytes through induction of apoptosis, cell arrest and suppression of matrix metalloproteinase.

ABSTRACT:

Context

Cinnamomi ramulus, the dry twig of Cinnamomum cassia Presl. (Lauraceae), has been reported to exert several activities such as antitumor, anti-inflammatory, and analgesic effects.

Objective

This study investigates the effects of an aqueous extract of Cinnamomi ramulus (ACR) on rheumatoid arthritis (RA).

Materials and methods

TNF-α-induced RA-derived fibroblast-like synoviocyte MH7A cells were incubated with ACR (0.1-2 mg/mL) for 24 h. The proliferation was tested using CCK-8 and colony formation assays. The migration and invasion abilities were measured using transwell tests and wound healing assays. Apoptosis and cell cycle were examined by flow cytometry. The potential mechanisms were determined by western blotting and quantitative real-
