In breast cancer, overexpression of miR-16 declined the self-renewal skills of BCSCs in mice and enhanced the sensitivity of doxorubicin to MCF-7 cells by targeting W1P1 [110]. Some miRNAs target proteins happen to be shown to become involved in apoptosis and boost chemosensitivity. miR-125b enhanced the sensitivity of temozolomide in glioblastoma CSCs by targeting pro-apoptotic Bcl-2 antagonist killer 1 [111]. In contrast, overexpression of miR-5100 enhanced cisplatin resistance in lung CSCs by targeting Rab6, a little GTP-binding protein, belongs to the Ras superfamily, that is regarded as a pro-apoptotic factor [112]. miRNAs alter many stemness-associated signaling pathways to overcome chemoresistance; among them, the Notch signal can be a crucial pathway. miR-136 improved paclitaxel sensitivity in ovarian cancer cells by repressing the Notch3 signaling pathway [113]. Similarly, miR-181b enhanced cisplatin sensitivity and decreased CSCs phenotype in lung cancer cells by targeting Notch signal [114]. Notch is also a direct target of miR-34a. Consequently, ectopic miR-34a expression enhanced doxorubicin sensitivity and repressed cancer stem cell properties in breast cancer cells by targeting the Notch1 [115]. 4. Conclusion More than the previous couple of years, scientific investigation has created therapeutic approaches to target many things involved in tumor improvement and cancer progression. Among various elements, chemoresistance followed by tumor relapse is really a big challenge in cancer remedy. Simultaneously, researchers found that miRNA is often used as a novel target for cancer therapy as it regulates DNA translational, mRNA and protein expression and reprograms numerous cellular signaling pathways. Therefore, miRNAs would bring new hope for cancer therapy [116]. Lately, various complete scientific investigation reveals that miRNA plays ‘the sword as well as the shield’ role in chemoresistance and tumor improvement [117]. miRNAs can boost the chemosensitivity by weakening the self-renewal abilities of CSCs, repressing the function of your ABC transporter, and altering the tumor microenvironment [118]. Besides, miRNAs also improve the apoptosis of cancer cells by targeting proteins involved inside the cell cycle, metastasis, and signaling pathways. Also, miRNA also can be used as a reputable diagnostic and prognostic marker to predict the stage and varieties of cancer [119,120]. Therefore, miRNA can be focused as a brand new therapeutic target to overcome chemoresistance, having said that, clinical NOP Receptor/ORL1 Compound correlation with advancement in miRNA-based diagnostic warrants future research and its therapeutic applications.
