In consequence, the differential expression levels of selected RNAs: circ-CDC27 (circ-0044235), circ-Med14 (circ-0140271), circ-TubD1 (circ-0044897), rno-miR-146a-5p, and TRAF6 were estimated in serum obtained from SLE-induced rats. The gene discussed is TUBD1; the disease is systemic lupus erythematosus.
