Role of miRNA Let-7 in Plasma of Rheumatoid Arthritis.

: Micro ribonucleic acids (miRNAs) are noncoding RNAs, recently implicated as potential biomarkers or therapeutic targets for autoimmune diseases such as rheumatoid arthritis (RA). The aim of this study is to assess the role of miRNA Let-7 in the plasma of RA. : Trained medical staff already enrolled for the study collected blood samples from healthy controls ( = 42) and RA patients ( = 44).
