miR-154 overexpression inhibited the proliferation, migration, and invasion of BCa cells, while knockdown of miR-154 yielded the opposite effects revealed miR-154 inhibited BC cell proliferation, migration, and invasion by regulating RSF1 and RUNX2 expression (15). is definitely important for BCa development (19). Till day, several miRNAs, including miR-520b (20), miR-7 (21), miR-375 (22) and miR-217 (23), have been confirmed to suppress cell growth and survival by focusing on ATG7 in tumor cells. Therefore, recognition of miRNAs that target ATG7 in BCa will facilitate the development of ATG7-centered therapies for BCa. In the present study, we targeted to elucidate the part and the underlying mechanism of miR-154 in BCa. We found significant downregulation of miR-154 in BCa cells and cell lines. We assessed the effect of miR-154 on cell proliferation, migration and invasion. Furthermore, we examined its effect on tumor growth access to food in specific pathogen-free conditions (55% moisture and 22C). The mice were randomly divided into two organizations (5 per group) and subcutaneously injected with T24 cells (2106 cells/mouse) that were YHO-13351 free base infected with either control lentivirus or a lentivirus that overexpressed miR-154. The tumor volume was determined by the following method: Tumor volume (mm3) = [size (mm)] [width (mm)]2 0.5. To determine the proliferation of the cells, Ki-67 staining of tumor cells from xenograft mice was performed as previously explained (25). The mice were sacrificed by cervical dislocation after 28 days. All animal studies were authorized by the Institutional Animal Care and Use Committee of the Shanghai Tenth People’s Hospital (Shanghai, China). Dual-Luciferase reporter assay The prospective genes were expected using bioinformatics analysis tools, including TargetScan (http://www.targetscan.org/vert_72/), ComiR (http://www.benoslab.pitt.edu/comir/) and miRANDA (http://www.microrna.org/). To confirm the presence of miR-154 binding sites in the ATG7 3-UTR, ATG7-wild-type 3-UTR (ATG7-wt) and ATG7-mutant 3-UTR (ATG7-mut) luciferase psiCHECK-2 reporter vectors were constructed. For the luciferase assay, T24 and UM-UC-3 cells were plated into 24-well plates and co-transfected with 100 ng luciferase psiCHECK-2 reporter vectors and miR-154/miR-154 inhibitor or bad control. All plasmid vectors were purchased from Promega Corp. (Madison, WI, USA). After 48 h of incubation the luciferase activity was assessed using a Luciferase Reporter Assay System (Promega Corp.), according to the manufacturer’s instructions. Statistical analysis Data were analyzed using SPSS 15.0 software (SPSS, Inc., Chicago, IL, USA). Results are offered as the mean standard deviation (SD) from at least three impartial experiments. The Student’s t-test was used to assess between-group differences, and one-way analysis of variance (ANOVA) plus post hoc Bonferroni test was used when comparing more than two groups. The association between the characteristics of patients and miR-154 expression was evaluated by Chi-square test or Fisher’s exact test. The relationship between ATG7 and miR-154 expression was quantified using Spearman’s correlation. Survival analysis was performed by Kaplan-Meier method and log-rank t-test. P-values findings, the overexpression of miR-154 caused significant inhibition of tumor growth (Fig. 6B). The miR-154 level in the xenograft tumor tissues was 100-fold higher than that in the control group (Fig. 6C). Furthermore, the miR-154-overexpressed group revealed low ATG7 levels when compared to that in the control group (Fig. 6D). In addition, Ki-67 staining revealed less proliferation in the miR-154 group (Fig. 6E). Collectively, the results indicated a critical role of miR-154 in suppressing BCa growth found that miR-154 was frequently downregulated in breast cancer tissues and that it functioned as a tumor suppressor in breast cancer by targeting E2F5 (13). Chen and Gao exhibited that miR-154 inhibited the growth of skin squamous cell carcinoma cells by targeting the p53 signaling pathway (30). Additionally, miR-154 was revealed to be downregulated in human hepatocellular carcinoma tissues and to inhibit cell proliferation, migration and invasion via suppression of ZEB2 (14). However, the role of miR-154 in BCa remains unclear. In the present study, we found marked downregulation of miR-154 in BCa tissues and cell lines, which was consistent with the results of a previous study (15). Moreover, a decreased miR-154 level was correlated with aggressive clinicopathological features, including advanced T stage, lymphatic invasion, and distant metastasis. Decreased miR-154 expression predicted unfavorable OS of BCa patients. To better characterize the role of miR-154 in BCa, functional studies were conducted. miR-154 overexpression inhibited the proliferation, migration, and invasion of BCa cells, while knockdown of miR-154 yielded the opposite effects revealed miR-154 inhibited BC cell proliferation, migration, and invasion by regulating RSF1 and RUNX2 expression (15)..To better characterize the role of miR-154 in BCa, functional studies were conducted. ATG7 is usually important for BCa development (19). Till date, several miRNAs, including miR-520b (20), miR-7 (21), miR-375 (22) and miR-217 (23), have been confirmed to suppress cell growth and survival by targeting ATG7 in tumor cells. Thus, identification of miRNAs that target ATG7 in BCa will facilitate the development of ATG7-based therapies for BCa.
