Abstract:
Cancer is an important health issue worldwide. Cancer therapy is multifaceted, and drug resistance is still the major limiting factor in the treatment of patients with this disease. Although the mechanisms of anticancer drug resistance have been broadly investigated, a massive biological signal pathway of Non-coding RNAs (ncRNAs) involved in this process has not been completely understood. Long noncoding RNAs (lncRNAs) are a kind of transcripts with a minimum length of 200 nucleotides in size, which have a limited potential for coding proteins. The roles of these RNA molecules have been evaluated in relation to several pathological processes, including tumor formation and progression. Increasing evidence has recently reported that non-coding RNAs (ncRNAs), particularly long non-coding RNAs, have significant roles in many cellular and genomic processes, and because of their potential in regulation specific genes, they are also involved in drug resistance. In this review, we review the literature on the features of lncRNA, their regulation roles in the gene expression related to chemo resistance, and the potential of these RNAs as targeted therapies for personalized treatment in cancers.
