“…It is well known that microRNAs (miRNAs) are an emerging group of gene expression modulators with critical roles in several biological processes like cell proliferation, apoptosis, differentiation, cell cycle progression, and organ development (Iorio, Casalini, Piovan, Braccioli, & Tagliabue, ; Rothschild, ; Singh & Mo, ; van Schooneveld et al, ). Additionally, it was proposed that these tiny molecules are involved in processes linked to formation and progression of various tumors and even development of different diseases such as Alzheimer’s, autism, fragile X syndrome, diabetes as well as heart diseases and allergic conditions (Mansoori et al, ; Mohammadi, Mansoori, & Baradaran, ; F. Yi et al, ). In the cancer cascade, miRNAs act mainly as oncogenes (oncomiRs) or tumor suppressors and miRNA profiling experiments demonstrated dysregulation of miRNAs in cancers when compared with normal tissues (Mansoori, Mohammadi, Shirjang, & Baradaran, ; Rothschild, ).…”
