摘要: MicroRNAs (miRNAs) are a relatively new class of non-coding RNA molecules. They 17-21 nucleotides (nt) in length and capable post-transcriptional gene silencing [1]. Pri-miRNAs transcribed the nucleus by polymerases II III before being processed miRNA maturing enzymes, Drosha (intranuclear) Dicer (extranuclear). The latter enzyme is also part RNA-induced complex (RISC), which regulates function once mature has been loaded onto it. After Watson-Crick base pairing occurs between target mRNA 5’ “seed region” RISC-loaded miRNA, will either be translationally repressed (in case weak mRNA/miRNA complementarity) or cleaved strong causing posttranscriptional [2]. Despite significant potential for miRNA-based therapy, little research performed on roles cutaneous squamous cell carcinoma (cSCC).
