Background

miR-223 promotes TGF (transforming growth factor)- β1 expression, the activated signalling of which is considered to be of great importance in the pathogenesis of emphysema, one of the two pathophysiological branches of COPD.
miR-223 is significantly upregulated in COPD patients (Roffel et al., 2021).
RT-qPCR (Reverse Transcription Quantitative Real-time Polymerase Chain Reaction), is a combination of RT-PCR and qPCR methods, and is commonly employed for the detection and quantification of RNA. The procedure involves the enzyme reverse transcriptase converting total RNA or messenger RNA (mRNA) to complementary DNA (cDNA). This cDNA is then amplified and used in quantitative PCR (qPCR) or real-time PCR to detect specific targets. This PCR method utilises a number of fluorescent chemicals to quantify the amount of DNA at each cycle in real-time.
