SUMMARY
The discussion centers on the increased expression of miR-141 following transfection with miRNA mimics, which significantly impairs insulin secretion at 16.7 mM glucose (P<0.05). The increase in miR-141 is attributed to the transfection process rather than the activity of RNA-dependent RNA polymerase, as mammals lack RDRPs for small RNA amplification. The RT-qPCR results likely reflect both the miRNA mimics and the endogenous miRNA levels.
