(A) Band showing total miRNA in denatured RNA gel isolated from human blood plasma (N=6) and curcuma longa (turmeric). (B) Band showing Clo-miR-14 PCR product run on 1.5% agarose gel from HC (N=8), RA (N=8), and Curcuma longa (turmeric). (C) Band showing Clo-miR-14 PCR product run on 1.5% agarose gel after incubation of miRNA at 100°C for 0 to 60 min. (D) Graph showing the level of miRNA degradation from 0 to 60 min while incubating at 100°C (cooking temperature). The graph shows three experimental replicates. M, molecular weight marker; min, minutes; *P≤0.05; HC, healthy control; PCR, polymerase chain reaction; RA, rheumatoid arthritis.
