ncRNAs play a significant role in regulating EMT, impacting cancer progression, including different types of non-coding RNAs such as miRNAs, LncRNAs, CircRNAs, etc.
RNA molecules lacking capacity in protein translation, are known as non-coding RNAs (ncRNAs). Growth, dif-ferentiation and migration are influenced by ncRNAs in cells. The abnormal expression of ncRNAs contributes to development of diseases, especially cancer. On the other hand, EMT is a vital mechanism for cancer invasion and diffusion in body. In this manuscript, role of ncRNAs in EMT regulation and subsequent effect on cancer pro-gression is investigated. The miRNAs regulate EMT by affecting signaling pathways including PI3K/Akt and PTEN to modulate cancer metastasis. Furthermore, miRNA and EMT interaction has close association with drug sensitivity of tumor cells. LncRNAs can affect EMT via targeting ZEB1/2, Twist and Snail among others and similarly, based on the impact on EMT, sensitivity of cancer cells to therapy increases or decreases. CircRNAs regulate both drug sensitivity and metastasis of cancers by affecting EMT mechanism. Noteworthy, circRNAs and lncRNAs are capable of sponging miRNAs in modulating EMT mechanism. Exosomes belong to extracellular vesicles with low size that can be secreted by cells in transferring genetic materials. The transfer of ncRNAs by exosomes is performed and they can also regulate EMT in cancer progression. Finally, ncRNAs regulating EMT mechanism are used for cancer diagnosis and prognosis.
