Dual-luciferase reporter assays were performed to validate whether KRAS was regulated by miR-143; Dual-luciferase assays indicated that KRAS was a direct target of miR-143 as subsequently demonstrated by qPCR and western blot analysis showing that infection of SW480 cells with Ad-ZD55-miR-143 resulted in the down-regulation of KRAS at both mRNA and protein levels;Role of miR 143 targeting KRAS in colorectal tumorigenesis; In particular among a panel of presumed targets generated by in silico analysis that may interact with these aberrantly expressed miRNAs KRAS oncogene has been further experimentally validated as the target of miR-143; First an inverse correlation between KRAS protein and miR-143 in vivo was found; Second KRAS expression in Lovo cells was significantly abolished by treatment with miR-143 mimic whereas miR-143 inhibitor increased KRAS protein level; Third luciferase reporter assay confirmed that miR-143 directly recognize the 3'-untranslated region of KRAS transcripts; Finally inhibition of KRAS expression by miR-143 inhibits constitutive phosphorylation of ERK1/2; Taken together the present study provides the first evidences that miR-143 is significant in suppressing colorectal cancer cell growth through inhibition of KRAS translation;MicroRNA 143 replenishment re sensitizes colorectal cancer cells harboring mutant but not wild type KRAS to paclitaxel treatment; Our results showed that miR-143 but not let-7b increased sensitization of KRAS mutant tumor cells to paclitaxel; Furthermore transfection of miR-143 but not let-7b mimic negatively regulated the expression of mutant but not wild-type KRAS; Combination of miR-143 mimic and paclitaxel induced the onset of apoptosis and reverted in vitro metastatic properties migration and invasion in KRAS mutant tumor cells; MiR-143 thus can be used as a chemosensitizer for the treatment of KRAS mutant tumors and warrants further investigations in in vitro and pre-clinical in vivo models;In turn the level of miR-143 in CRC cells decreasing the amount of MACC1 metastasis-associated in colon cancer-1 and oncogenic KRAS protein may be utilized as a prognostic marker;Stable miR-143 or miR-145 overexpression increased cell sensitivity to cetuximab resulting in a significant increase of cetuximab-mediated ADCC independently of KRAS status;miR 143 decreases prostate cancer cells proliferation and migration and enhances their sensitivity to docetaxel through suppression of KRAS; The expression level of miR-143 and its target gene KRAS were measured by realtime PCR and western blotting respectively; Our results revealed an inverse correlation of expression between miR-143 and KRAS protein in prostate cancer samples Pearson's correlation scatter plots: R = -0.707 P < 0.05; These findings suggest that miR-143 plays an important role in prostate cancer proliferation migration and chemosensitivity by suppressing KRAS and subsequent inactivation of MAPK pathway which provides a potential development of a new approach for the treatment of prostate cancer ;;tumorigenesis;;metastasis;;

downregulates KRAS NRAS and MAPK1; and decreases AML growth; The delivery of miR-181a mimics to target AML cells using transferrin-targeting lipopolyplex nanoparticles NP increased mature miR-181a; downregulated KRAS NRAS and MAPK1; and resulted in decreased phosphorylation of the downstream RAS effectors;MiR 181a 5p inhibits cell proliferation and migration by targeting Kras in non small cell lung cancer A549 cells; Luciferase activity assay results demonstrated that two binding sites of Kras could be directly targeted by miR-181a-5p; Furthermore Kras was down-regulated by miR-181a-5p at both transcriptional and translational levels; SiRNA-mediated Kras down-regulation could mimic the effects of miR-181a-5p mimic in A549 cells; Our findings suggest that miR-181a-5p plays a potential role in tumor suppression by partially targeting Kras and has the potential therapeutic application in NSCLC patients ;;
