Anti-angiogenic Drug Resistance: Roles and Targeting of Non-coding RNAs (microRNAs and long non-coding RNAs)

Abstract: Cancers with a high capability for angiogenesis are frequently regarded as being difficult to treat. Anti-angiogenesis drugs are considered the primary therapy for these types of cancers. Due to intrinsic or acquired anti-angiogenesis resistance, therapies result in moderate clinical consequences, despite some hopeful findings. The importance of non-coding RNAs (ncRNAs) such as microRNAs (miRNAs), long non-coding (lncRNAs), and circular RNAs (circRNAs) in drug resistance mechanisms in cancer treatment has been discovered in the previous decade. Anti-angiogenic drug resistance can be influenced by ncRNA dysregulation. Hence, ncRNAs are potential drug resistance targets for new anti-angiogenic drugs in the inhibition of angiogenesis in tumors. Furthermore, some ncRNAs can be employed as biomarkers for anti-angiogenic drug responses and can be used to monitor cancer non-invasively. Combination treatment approaches, combined with routine anti-angiogenesis and some drugs that target the ncRNAs causing resistance, can be potential ways to overcome anti-angiogenesis resistance. For the first time, we explain the mechanisms of anti-angiogenic drug resistance and the related miRNAs and lncRNAs and their signaling pathways in commonly used antiangiogenic drugs implicated in this review article. These ncRNAs could be suggestions for targeting and reducing anti-angiogenic drugs in the future.
