Abstract (original English)

Objective The immunoregulatory properties of mesenchymal stromal/stem cells (MSCs) bring a promise for the treatment of inflammatory diseases. However, their ability to suppress the immune system is unstable. To enhance their effectiveness against immune responses, it may be necessary to manipulate MSCs. Although some dsRNA transcripts come from invading viruses, the majority of dsRNA has an endogenous origin and is known as endo-siRNA. DICER1 is a ribonuclease protein that can generate small RNAs to modulate gene expression at the post-transcriptional level. We aimed to evaluate the expression of several immune-related genes at mRNA and protein levels in MSCs overexpressing DICER1 exogenously. Materials and methods In this comparative transcriptomic experimental study, the adipose-derived MSCs (Ad-MSCs) were transfected using the pCAGGS-Flag-hsDicer vector for the DICER1 overexpression. Following the RNA extraction, mRNA expression level of DICER1 and several inflammatory cytokines were examined. We performed a relative real-time polymerase chain reaction (PCR) assay and transcriptome analysis between two groups including DICER1- transfected MSCs and control MSCs. Moreover, media from the transfected MSCs were evaluated for various interferon response factors by ELISA. Results The overexpression of DICER1 is associated with a significant increase in the mRNA expression level o
