miR‑137 decreases proliferation, migration and invasion in rheumatoid arthritis fibroblast‑like synoviocytes

Downregulation of microRNA‑221 decreases migration and invasion in fibroblast‑like synoviocytes in rheumatoid arthritis.

MicroRNAs (miRNAs/miRs) are a group of non-coding RNAs that regulate the activity of target mRNAs and cellular processes, and which have been implicated in the pathogenesis of autoimmune diseases. miR-221 is one of the miRNAs that regulate cell proliferation, invasion and apoptosis in tumors. However, the role of miR-221 in rheumatoid arthritis (RA) remains to be fully elucidated. Therefore, th...

Phosphoinositide 3-Kinase d Regulates Migration and Invasion of Synoviocytes in Rheumatoid Arthritis

Rheumatoid Arthritis Migration and Invasion of Synoviocytes in Regulates δ Phosphoinositide 3-Kinase

Phosphoinositide 3-kinase δ regulates migration and invasion of synoviocytes in rheumatoid arthritis.

Cartilage destruction mediated by invasive fibroblast-like synoviocytes (FLS) plays a central role in pathogenesis of rheumatoid arthritis (RA). Increased cell migration and degradation of extracellular matrix are fundamental to these processes. The class I PI3Ks control cell survival, proliferation, and migration, which might be involved in cartilage damage in RA. PI3Kδ isoform was recently id...

Hypericin-photodynamic therapy inhibits proliferation and induces apoptosis in human rheumatoid arthritis fibroblast-like synoviocytes cell line MH7A

Objective(s): To elucidate the effects and potential mechanisms of hypericin-photodynamic therapy (HYP-PDT) for treating the human rheumatoid arthritis (RA) fibroblast-like synoviocyte (FLS) MH7A cell-line. Materials and Methods: MH7A cells were subjected to HYP-PDT intervention and apoptosis was evaluated via MTT, nuclear staining, and flowcytometry analyses. Intracellular reactive oxygen spec...
