Abstract
PURPOSE This research aimed to explore the regulatory molecular mechanism among circular RNA (circ)_0011373, microRNA (miR)-1271, and lipoprotein receptor-related protein 6 (LRP6) in papillary thyroid carcinoma (PTC). METHODS Quantitative real-time PCR (qRT-PCR) assay was adopted to measure the expression of circ_0011373, miR-1271, and LRP6 mRNA. Furthermore, cell cycle distribution, apoptosis, migration and invasion were investigated by flow cytometry and transwell assay, respectively. The target relationship between miR-1271 and circ_0011373 or LRP6 was predicted by using the Starbase website and DIANA TOOL and verified by dual-luciferase reporter and RIP assay. Protein expression levels of LRP6, p-mTOR, mTOR, p-AKT, AKT, p-PI3K, and PI3K were tested by Western blot. The function of circ_0011373 on PTC tumor growth was validated by the xenograft tumor model in vivo. RESULTS Circ_0011373 and LRP6 were upregulated, while miR-1271 was downregulated in PTC tissues and cell lines. Moreover, knockdown of circ_0011373 inhibited cell cycle, migration, and invasion and promoted apoptosis. Of particular importance was the fact that circ_0011373 directly interacted with miR-1271 and miR-1271 inhibitor was able to reverse the effect of circ_0011373 knockdown on PTC cell progression. Meanwhile, LRP6 was directly targeted by miR-1271, and its expression was positively regulated by circ_0011373. We further confirmed that miR-1271 overexpression suppressed cell cycle, migration, and invasion and enhanced apoptosis by regulating LRP6. In addition, circ_0011373 knockdown restrained PTC tumor growth in vivo. CONCLUSION Circ_0011373 might be able to regulate PTC cell cycle, migration, invasion, and apoptosis by regulating the miR-1271/LRP6 axis.

Abstract
To investigate the mechanism by which Cangxi Tongbi Capsules promote chondrocyte autophagy to inhibit knee osteoarthritis(KOA) progression by regulating the circRNA_0008365/miR-1271/p38 mitogen-activated protein kinase(MAPK) pathway. The cell and animal models of KOA were established and intervened with Cangxi Tongbi Capsules, si-circRNA_0008365, si-NC, and Cangxi Tongbi Capsules combined with si-circRNA_0008365. Flow cytometry and transmission electron microscopy were employed to determine the level of apoptosis and observe autophagosomes, respectively. Western blot was employed to reveal the changes in the protein levels of microtubule-associated protein light chain 3(LC3)Ⅱ/Ⅰ, Beclin-1, selective autophagy junction protein p62/sequestosome 1, collagen Ⅱ, a disintegrin and metalloproteinase with thrombospondin motifs 5(ADAMTS-5), and p38 MAPK. The mRNA levels of circRNA_0008365, miR-1271, collagen Ⅱ, and ADAMTS-5 were determined by qRT-PCR. Hematoxylin-eosin staining was employed to reveal the pathological changes of the cartilage tissue of the knee, and enzyme-linked immunosorbent assay to measure the levels of interleukin-1β(IL-1β) and tumor necrosis factor-alpha(TNF-α). The chondrocytes treated with IL-1β showed down-regulated expression of circRNA_0008365, up-regulated expression of miR-1271 and p38 MAPK, lowered autophagy level, increased apoptosis rate, and accelerated catabolism of extracellular matrix. The intervention with Cangxi Tongbi Capsules up-regulated the expression of circRNA_0008365, down-regulated the expression of miR-1271 and p38 MAPK, increased the autophagy level, decreased the apoptosis rate, and weakened the catabolism of extracellular matrix. However, the effect of Cangxi Tongbi Capsules was suppressed after interfering with circRNA_0008365. The in vivo experiments showed that Cangxi Tongbi Capsules dose-dependently inhibited the p38 MAPK pathway, enhanced chondrocyte autophagy, and mitigated articular cartilage damage and inflammatory response, thereby inhibiting the progression of KOA in rats. This study indicated that Cangxi Tongbi Capsules promoted chondrocyte autophagy by regulating the circRNA_0008365/miR-1271/p38 MAPK pathway to inhibit the development of KOA.

Abstract
BACKGROUND Endometriosis is a common gynecological condition with a substantial economic burden on society. It is known that both genetic and environmental factors are contributing to the phenotypic development of the disease. MicroRNAs have a vital role in the pathogenesis of endometriosis. miR-1271 and its direct target gene, GRB2 (growth factor receptor-bound protein 2), expression have been studied in gynecologic cancers, while their role in endometriosis has not been studied. OBJECTIVE We measured miR-1271 and GRB2 gene expression in the eutopic and ectopic tissues of patients (endometrial tissues) in contrast to the control samples from healthy women. MATERIALS AND METHODS In this study, a total of 45 samples (15 control samples, 15 eutopic samples and 15 ectopic samples) were collected. We used qRT-PCR (quantitative polymerase chain reaction) to evaluate the expression levels of the miR-1271 and GRB2 gene. RESULTS We observed inverse expression of miR-1271 and GRB2 gene. MiR-1271 expression was significantly reduced in patients with endometriosis compared with healthy women. While there was a noticeable increase in the expression level of its target gene, GRB2, in tissues of endometriosis patients compared with normal control samples. CONCLUSION We have shown an inverse relationship between the reduction of miR-1271 expression level and increase in the expression level of GRB2, therefore, increased GRB2 expression in endometriosis tissues can be due to decreased expression of this microRNA. Our findings suggested that miR-1271 maybe play a role as a biomarker in the diagnosis of patients with endometriosis.

Abstract
Type 2 diabetes is characterized by insulin resistance (IR) and increased hepatic glucose production. MicroRNAs (miRs) are considered regulators of glucose metabolism. This study evaluated anti-diabetic activity of hydroxybenzoic acid derivatives and determined the involvement of miR-1271. Among the hydroxybenzoic acid derivatives, gallic acid (GA) showed the best anti-diabetic activity. GA improved free fatty acid (FFA)-induced hepatic IR, increased glucose consumption, and decreased reactive oxygen species. GA inhibited the upregulation of miR-1271 induced by FFA and upregulated its targets such as p-IRS, p-PI3K, p-AKT, and p-FOXO1, accompanied by the regulation of glucose metabolism genes. The involvement of miR-1271 in the protective effect of GA against IR was further confirmed in the presence of miR-1271 mimic or miR-1271 inhibitor. Our results suggest that GA attenuates IR via the miR-1271/IRS/PI3K/AKT/FOXO1 pathway and thus might be considered for the management of IR. PRACTICAL APPLICATIONS: MicroRNAs can regulate insulin resistance by affecting protein expressions involved in insulin signaling. Experimental data suggest that some phytochemicals regulate the expression of various microRNAs. However, it is not clear whether phenolic acids play any role in the hepatic insulin signaling pathway through the regulation of microRNA expression. This study assessed the anti-diabetic activity of hydroxybenzoic acid derivatives through down-regulation of microRNA-1271 and its association with the IRS1/PI3K/AKT/FOXO1 pathways. This research will be able to offer basic information regarding a potential therapeutic strategy to control hepatic insulin resistance.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is the third leading cause of cancer death, causing about 750000 deaths worldwide every year. Patients with advanced hepatocellular carcinoma will often only receive transcatheter arterial chemoembolization (TACE). Glypican-3 (GPC3) is one of the most promising serum markers for HCC. Abnormal expression of miRNAs may be involved in the occurrence and development of tumor.
AIM To explore the value of miR-1271 and GPC3 in evaluating the prognosis of patients with HCC after TACE.
METHODS From January 2016 to December 2018, 162 patients with advanced HCC who received TACE in our hospital were selected into the cancer group, and 162 patients who underwent physical examination during the same period were selected into the health group. The patients in the HCC group were treated with TACE. The changes of serum GPC3 and circulating miR-1271 in the HCC before and after TACE were analyzed. The expression of serum GPC3 was detected by enzyme-linked immunosorbent assay, and the expression of circulating miR-1271 was detected by real-time quantitative polymerase chain reaction. The methodological results of sensitivity, specificity, and accuracy of miR-1271 and GPC3 alone and joint detection of HCC were also evaluated.
RESULTS The level of serum GPC3 in patients with HCC was significantly higher than that in healthy controls. GPC3 levels were increased in both HCC patients and those treated with TACE compared with healthy controls. After TACE, the level of serum GPC3 was significantly lower than that before treatment (P < 0.05), and the level of circulating miR-1271 was significantly higher than that before treatment (P < 0.05). There were 112 cases (69.14%) with remission (complete remission + complete remission + stable disease) and 50 cases (30.86%) with relapse disease progression in HCC patients. After TACE, the miR-1271 level in patients with remission and relapse was lower than that in the healthy group, and the GPC3 level was higher than that in the healthy group, the differences were statistically significant (P < 0.05). The miR-1271 of relapsed patients was lower than that of remission patients, and the level of GPC3 was higher than that of remission patients, and the difference was statistically significant (P < 0.05). The sensitivity of combined detection of miR-1271 and GPC3 was significantly higher than that of single detection, and the difference was statistically significant (P < 0.05); while the specificity of the two combined detections was lower than that of the single detection; and the accuracy was slightly higher than that of single detection, but the difference was not statistically significant.
CONCLUSION The level of miR-1271 in patients with HCC was significantly increased and the level of GPC3 was decreased after TACE. Monitoring the levels of serum GPC3 and circulating miR-1271 has important clinical reference value for evaluating the prognosis of patients with HCC. The levels of serum GPC3 and circulating miR-1271 may help to determine tumor recurrence, evaluate survival status, and guide the next step of treatment.

Abstract
Long non-coding RNAs (lncRNAs) have recently emerged as key regulators of the occurrence and progression of various human cancers, including colorectal cancer. However, the regulatory mechanism of lncRNAs in the tumorigenesis of colorectal cancer remains poorly understood. In this study, we aimed to elucidate the potential role of lncRNA HCG18 in colorectal cancer. Herein, we found that HCG18 expression was significantly upregulated in colorectal cancer tissues and cell lines. Knockdown of HCG18 significantly inhibited the growth and invasion of colorectal cancer cells, while its overexpression had the opposite effect. Moreover, HCG18 was identified as a sponge of miR-1271. Our results showed that knockdown of HCG18 markedly upregulated miR-1271 expression in colorectal cancer cells. Notably, HCG18 expression was inversely correlated with miR-1271 expression in colorectal cancer specimens. Further investigation revealed that HCG18 contributed to the enhancement of MTDH/Wnt/β-catenin signalling in colorectal cancer cells. The antitumour effect of HCG18 inhibition was significantly reversed by miR-1271 inhibition or MTDH overexpression. Overall, the results of our study demonstrate that HCG18 exerts a potential oncogenic function in colorectal cancer by enhancing MTDH/Wnt/β-catenin signalling via sponging of miR-1271, highlighting the importance of HCG18/miR-1271/ MTDH/Wnt/β-catenin signalling in the progression of colorectal cancer.

Abstract
Objective MicroRNA-1271 (miR-1271) has a role in suppressing cell growth, cell cycle and promoting cell apoptosis in many cancers. This research was to explore the great role of miR-1271 in ovarian cancer (OC). Patients and Methods RT-qPCR was utilized to evaluate the mRNA levels of miR-1271 and its target gene. The proliferative and invasive abilities were measured using Cell Counting Kit-8 and transwell assays. The overall survival rate of OC patients was assessed by Kaplan–Meier method. Results miR-1271 was downregulated in OC tissues, and downregulation of miR-1271 predicted a poor outcome of the OC patients. Zinc finger E-box binding homeobox 1 (ZEB1) was a target gene of miR-1271 and its expression was regulated by miR-1271 in OC. The expression of miR-1271 had a negative connection with the expression of ZEB1 in OC tissues. miR-1271 inhibited cell viability and invasion-mediated epithelial–mesenchymal transition in SKOV3 cells. ZEB1 reversed partial roles of miR-1271 on viability and invasion in OC. Conclusion miR-1271 inhibited cell proliferation and invasion-mediated EMT in OC. The newly identified miR-1271/ZEB1 axis provides novel insight into the pathogenesis of OC.

Abstract
Differences in inflammatory factors IL-6 and miR-1271 expression levels between elderly and young gastric cancer patients were investigated. A retrospective analysis of 146 cases of gastric cancer tissue and normal fresh tissue specimens diagnosed in The First Hospital of Lanzhou University from January 2013 to January 2015, was performed. Patients aged ≥60 years were the elderly group (76 cases), and patients ≤40 years were the youth group (70 cases). RT-qPCR was used to detect the relative expression levels of IL-6 and miR-1271, and Kaplan-Meier for a postoperative 3-year survival analysis of young and elderly gastric cancer patients. The expression level of IL-6 and miR-1271 was significantly higher in young gastric cancer tissues than that in elderly gastric cancer tissues (P<0.001). The expression levels of IL-6 and miR-1271 were correlated with age, tumor size, lymph node metastasis, distant metastasis, clinical stage and differentiation degree of gastric cancer patients (P<0.05). The 3-year overall survival rate of patients with a low expression of IL-6 and miR-1271 was better than that of patients with a high expression in young and elderly gastric cancer (P<0.05). IL-6 was highly expressed but miR-1271 expression was low in gastric cancer tissues. The 3-year overall survival rate of patients with the low expression of IL-6 was better than that of patients with the high expression in young and elderly gastric cancer. The high expression of miR-1271 was better than that of patients with the low expression in young and elderly gastric cancer. Findings of the present study provide data support for the clinical evaluation of differences between young and elderly gastric cancer and their prognosis.

Abstract
BACKGROUND Breast cancer is the most common cancer among women worldwide, and approximately 70% of breast cancers are hormone receptor-positive and express estrogen receptor-α (ERα) or/and progesterone receptor. ERα has been identified to promote the growth of primary breast cancer, however, it can also antagonize signaling pathways that lead to epithelial-mesenchymal transition (EMT), including transforming growth factor-β (TGF-β) signaling. miRNA alteration or dysfunction is involved in cancer development and progression. Although miR-1271 has identified as a tumor suppressor in various cancers, the role of miR-1271 in breast cancer is still limited. METHODS The effect of miR-1271 on breast cancer progression was investigated both in vitro and in vivo. The EMT-related protein expression levels and localization were analyzed by western blotting and immunofluorescence, respectively. Chromatin immunoprecipitation and dual-luciferase reporter assays were used to validate the regulation of ERα-miR-1271-SNAI2 feedback loop. RESULTS miR-1271 suppresses breast cancer progression and EMT phenotype both in vitro and in vivo by targeting SNAI2. Estrogen reverses TGF-β-induced EMT in a miR-1271 dependent manner. Furthermore, ERα transactivates the miR-1271 expression and is also transcriptionally repressed by SNAI2. CONCLUSIONS Our data uncover the ERα-miR-1271-SNAI2 feedback loop and provide a mechanism to explain the TGF-β network in breast cancer progression.

Abstract
MicroRNAs (miRNAs) have been reported to exert important effects on the initiation, progression and metastasis of glioblastoma multiforme (GBM). In this study, we aimed to explore the regulation role of miR-1271 on the development of GBM. We found that miR-1271 was a Bcl-2-targeting miRNA, and the levels of miR-1271was decreased in samples from patients with GBM, compared with those from corresponding normal tissue samples. On the other hand, the levels of miR-1271 were inversely related to the levels of Bcl-2, which have been significantly increased in GBM samples. The overall survival was poorer in patients with low levels of miR-1271, compared to those with high levels of miR-1271. In vitro, the chemo-resistant cell survival mediated with Bcl-2 was inhibited by overexpression of miR-1271 and was enhanced by depletion of miR-1271. Thus, the chemo-resistance of GBM cells may be promoted after suppressing miR-1271 through cell survival mediated with Bcl-2. The prognosis of patients with GBM receiving chemotherapy may be improved by overexpressing miR-1271 in cancerous cells.

Abstract
Epigenetic dysregulation is a major driver of tumorigenesis. To identify tumor-suppressive microRNAs repressed by DNA methylation in gastric cancer (GC), we analyzed the genome-wide DNA methylation and microRNA expression profiles of EpCAM+/CD44+ GC cells. Among the set of microRNAs screened, miR-1271 was identified as a microRNA repressed by DNA methylation in GC. Forced miR-1271 expression substantially suppressed the growth, migration, and invasion of GC cells. To identify candidate target genes and signaling pathways regulated by miR-1271, we performed RNA sequencing. Among the genes down-regulated by miR-1271, MAP2K1 (MEK1) was significantly repressed by miR-1271, and the associated ERK/MAPK signaling pathway was also inhibited. TEAD4 was also repressed by miR-1271, and the associated YAP1 signatures within genes regulated by miR-1271 were significantly enriched. These findings uncovered MEK1 and TEAD4 as novel miR-1271 targets and suggest that the epigenetic silencing of miR-1271 is crucial for GC development.

Abstract
Accumulating evidence has suggested that calpain small subunit 1 (Capn4) plays an important role in the development and progression of malignant tumors. However, little is known about the role of Capn4 in colorectal cancer (CRC). In this study, we aimed to investigate the potential role of Capn4 in CRC and the regulation of Capn4 by microRNAs (miRNAs). Here, we found that Capn4 expression was highly up-regulated in CRC cell lines. Knockdown of Capn4 by siRNA significantly inhibited the proliferation and invasion of CRC cell lines. Furthermore, knockdown of Capn4 suppressed Wnt signaling in CRC cells. Interestingly, Capn4 was found to be a target gene of miR-1271, a tumor suppressive miRNA. The results showed that miR-1271 negatively regulated Capn4 expression in CRC cells. An inverse correlation between miR-1271 and Capn4 was also shown in CRC clinical tissues. Moreover, the overexpression of miR-1271 suppressed the proliferation, invasion and Wnt signaling of CRC cells. Importantly, we found that the restoration of Capn4 expression significantly reversed the antitumor effects of miR-1271 in CRC cells. Overall, these results suggest that miR-1271 inhibits the proliferation and invasion of CRC cells by down-regulating Capn4. Our study suggests that Capn4 and miR-1271 may serve as potential therapeutic targets for the treatment of CRC.

Abstract
Attenuation of estrogen receptor α (ERα) expression via unknown mechanism(s) is a hallmark of endocrine-resistant breast cancer (BCa) progression. Here, we report that miR-1271 was significantly down-regulated in letrozole-resistant BCa tissues and in letrozole-resistant BCa cells. miR-1271 directly targeted the chromatin of DNA damage-inducible transcript 3 (DDIT3) gene. miR-1271 expression level was inversely correlated to DDIT3 mRNA level in BCa biopsies. Form a mechanistic standpoint, reintroduction of exogenous miR-1271 could effectively restore ERα level via inhibiting DDIT3 expression, thereby potentiating letrozole sensitivity in BCa cells. Moreover, DDIT3 deregulation promoted letrozole-resistance by acting as a potent corepressor of ESR1 transcription. Taken together, we have identified that disruption of the miR-1271/DDIT3/ERα cascade plays a causative role in the pathogenesis of letrozole resistance in BCa.

Abstract
Obesity and metabolic diseases are closely associated with insulin resistance. Obesity-induced miRNAs are also considered to be potential contributors to the development of insulin resistance and type 2 diabetes. Previously, the expression of miR-1271 was reported to be upregulated in the liver of diet-induced obese mice (Yang et al., 2016) [1]. In this data article, multiple in silico analysis predicted FOXO1 gene to be a direct target of miR-1271. Dual luciferase reporter gene analysis showed that miR-1271 suppressed FOXO1 expression by direct binding to 3′UTR. The overexpression of miR-1271 reduced the protein expression of FOXO1, thereby reducing the transcription of PEPCK, a downstream target of FOXO1. The data is related to a research article entitled "MiR-1271 upregulated by saturated fatty acid palmitate provokes impaired insulin signaling by repressing INSR and IRS-1 expression in HepG2 cells" (Yang et al., 2016) [1].

Abstract
Circular RNA (circRNA) is a key regulator in the development and progression of human cancers, however its role in breast cancer tumorigenesis is not well understood. The present study aims to investigate the expression profiles and potential modulation of circRNA on breast cancer carcinogenesis. Human circRNA microarray was performed to screen for abnormally expressed circRNA in breast cancer tissue. Results found circ-ABCB10, was significantly up-regulated in breast cancer tissue. And results were replicated in a larger sample size. In vitro, loss-of-function experiments showed circ-ABCB10 knockdown suppressed the proliferation and increased apoptosis of breast cancer cells. Bioinformatics prediction program predicted the complementary sequence within circ-ABCB10 and miR-1271, which was validated by luciferase reporter assay. Finally, miR-1271 rescued the function of circ-ABCB10 on breast cancer cells, confirming the sponge effect of circ-ABCB10 on miR-1271. Overall, results identified a new functional circ-ABCB10 in breast cancer tumorigenesis, and reveal the important regulatory role of circ-ABCB10 through sponging miR-1271, providing a novel insight for breast cancer pathogenesis.

Abstract
The dysregulation of transcription factors contributes to the unlimited growth of cancer cells. Zic2 has been shown to be crucial to the progression of human cancers. However, its role in hepatocellular carcinoma (HCC) remains unclear. Our data showed that Zic2 expression gradually increased from normal to cancer to metastatic tissues. Zic2 overexpression promoted, whereas Zic2 knockdown inhibited, cell proliferation and migration in vitro as well as tumor growth and metastasis in vivo. Gene microarray results indicated that PAK4 was a potential target of Zic2. The knockdown of Zic2 decreased, whereas Zic2 re-expression increased, the expression of PAK4. ChIP and luciferase assays indicated that Zic2 directly bound to the PAK4 promoter and modulated its activity. PAK4 interference attenuated Zic2-mediated cell growth via modulating the Raf/MEK/ERK pathway. In a cohort of 615 patients, Zic2 was positively correlated with PAK4 and associated with worse overall and disease-free survival. Multivariate analyses revealed that Zic2 and PAK4 were independent indicators of a poor outcome in HCC. In addition, Zic2 expression was inversely correlated with miR-1271 expression. Re-introduction of miR-1271 attenuated Zic2-promoted cell proliferation and migration. Taken together, our findings suggest that the newly identified miR-1271/Zic2/PAK4 axis plays an important role in HCC progression and may serve as a potential therapeutic target for HCC.

Abstract
The forkhead transcription factor FOXK2 has been implicated in the progression of human cancers, but its role and clinical significance in hepatocellular carcinoma (HCC) have not been explored. Here we showed that FOXK2 expression was increased and associated with tumor size, TNM stage and vascular invasion. High FOXK2 expression was correlated with poor overall and disease-free survival in two independent cohorts consisting of 864 patients with HCC. The prognostic value of FOXK2 was validated by stratified survival analyses in subgroups difined by factors contributing to worse survival. Multivariate Cox regression model revealed that FOXK2 served as an independent factor for overall survival. The FOXK2 expression was reversely connected with miR-1271-5p in clinical samples. Re-introduction of miR-1271 decreased FOXK2 at both mRNA and protein levels. Luciferase assay confirmed that FOXK2 was a direct target of miR-1271 in HCC cells. Overexpression of FOXK2 enhanced the cell growth and migration, whereas FOXK2 silence resulted in the opposite phenotypes. Further studies demonstrated that FOXK2 exerted oncogenic activity via activation of PI3K/AKT signaling pathway. Collectively, our data suggest FOXK2 as an oncogene and a promising prognostic biomarker in HCC. Targeting the newly identified miR-1271/FOXK2/AKT axis may represent a potential strategy for HCC intervention.

Abstract
Disheveled-Axin domain containing 1 (DIXDC1) is involved in the development and progression of multiple cancers. However, the function significance of DIXDC1 in prostate cancer remains unclear. In this study, we investigated the function of DIXDC1 in prostate cancer and the regulation of DIXDC1 by microRNAs (miRNAs). We found that DIXDC1 was highly expressed in prostate cancer cells. Knockdown of DIXDC1 by small interfering RNAs markedly suppressed proliferation, invasion and Wnt signaling in prostate cancer cells. DIXDC1 was identified as a target gene of miR-1271 by bioinformatics analysis, dual-luciferase reporter assay, real-time quantitative polymerase chain reaction and Western blot analysis. Furthermore, DIXDC1 expression was inversely correlated with miR-1271 expression in prostate cancer tissues. The overexpression of miR-1271 significantly inhibited proliferation, invasion and Wnt signaling in prostate cancer cells. However, the inhibition of miR-1271 exhibits the opposite effects. Moreover, the overexpression of DIXDC1 significantly reversed the inhibitory effects of miR-1271 overexpression. Taken together, our results suggest that DIXDC1 plays an important role in regulating prostate cancer cell proliferation and invasion. Targeting DIXDC1 by miR-1271 may be a promising therapeutic strategy for prostate cancer.

Abstract
Non-small cell lung cancer (NSCLC) is a common lung cancer of high incidence. Since NSCLCs often grow rapidly, it is critical to elucidate the underlying mechanisms. Previous studies have shown that microRNAs (miRNAs) play critical roles in the carcinogenesis of NSCLC. Specifically, miR-1271 has been shown to downregulate in NSCLC cells. However, whether the downregulation of miR-1271 relates to carcinogenesis of NSCLC is unknown. Here, we analyzed the levels of miR-1271 and mTor in NSCLC specimens and studied their correlation. We performed bioinformatics analysis and luciferase-reporter assay to study the association of miR-1271 with mTor mRNA. We analyzed miR-1271 levels in NSCLC cells and studied their effects on mTor levels. The growth of miR-1271-modified NSCLC cells was evaluated in vitro in an MTT assay, and in vivo by bioluminescence. We detected significantly higher levels of mTor and significantly lower levels of miR-1271 in the NSCLC specimens, compared to the paired non-tumor lung tissues. We found that miR-1271 bound to the 3'UTR of mTor mRNA to prevent its translation. Overexpression of miR-1271 in NSCLC cells decreased mTor protein levels, whereas inhibition of miR-1271 increased mTor protein levels, without affecting mTor transcripts. Moreover, overexpression of miR-1271 suppressed the NSCLC growth in vitro and in vivo, while inhibition of miR-1271 significantly increased NSCLC growth. Together, these data suggest that in NSCLC, miR-1271 may inhibit the cancer cell growth through mTor suppression.

Abstract
MicroRNAs (miRNAs) are short, non-coding RNAs (∼ 22 nt) that play important roles in the pathogenesis of human diseases by negatively regulating numerous target genes at posttranscriptional level. However, the role of microRNAs in lung cancer, particularly non-small-cell lung cancer (NSCLC), has remained elusive. In this study, two microRNAs, miR-1271 and miR-628, and their predicted target genes were identified differentially expressed in NSCLC by analyzing the miRNA and mRNA expression data from NSCLC tissues and their matching normal controls. miR-1271 and its target gene HOXA5 were selected for further investigation. CCK-8 proliferation assay showed that the cell proliferation was promoted by miR-1271 in NSCLC cells, while miR-1271 inhibitor could significantly inhibited the proliferation of NSCLC cells. Interestingly, migration and invasion assay indicated that overexpression of miR-1271 could significantly promoted the migration and invasion of NSCLC cells, whereas miR-1271 inhibitor could inhibited both cell migration and invasion of NSCLC cells. Western blot showed that miR-1271 suppressed the protein level of HOXA5, and luciferase assays confirmed that miR-1271 directly bound to the 3'untranslated region of HOXA5. This study indicated indicate that miR-1271 regulates NSCLC cell proliferation and invasion, via the down-regulation of HOXA5. Thus, miR-1271 may represent a potential therapeutic target for NSCLC intervention.
