ZHAO X, HE L. Hsa-circ-0006091 modulates the proliferation of hepatocellular carcinoma via the miR-622/CCNB1 axis. Turk J Med Sci 2023; 53:1367-1378. [PMID: 38813026 PMCID: PMC10763780 DOI: 10.55730/1300-0144.5703] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2023] [Revised: 10/26/2023] [Accepted: 05/31/2023] [Indexed: 05/31/2024] Open
Abstract
Background/aim Hepatocellular carcinoma (HCC) is a common type of cancer. We hypothesize that circular RNA-0006091 (circ-0006091) affects the progression of HCC. The study aims to investigate the effect of circ-0006091 in HCC cells. Materials and methods The levels of circ-0006091, microRNA-622 (miR-622), and cyclin B1 (CCNB1) were assayed using qRT-PCR and western blotting. The metastasis of the HCC cells was measured with wound healing and transwell assays. The protein expression levels of MMP-2 and MMP-9 were assayed with western blotting. Dual-luciferase reporter and RNA-pulldown assays were used to determine the link between miR-622 and circ-0006091 or CCNB1. Mice-based tests were used to determine the effect of circ-0006091 on the proliferation of HCC cells. Results The levels of circ-0006091 and CCNB1 were increased in the HCC cells, but miR-622 was down-regulated. Deficiency of circ-0006091 reduced the metastasis of the HCC cells, and silencing of circ-0006091 decreased the activities of MMP-2 and MMP-9 in the same cells. Circ-0006091 modulated the CCNB1 level in the HCC cells via miR-622. Silencing of circ-0006091 suppressed the proliferation of the HCC cells in vivo. Conclusion Circ-0006091 regulated HCC cell metastasis via the miR-622/CCNB1 axis, a possible therapeutic target in managing HCC.

Zhang J, Li X, Yang J, Zhang Y. MiR-1254 suppresses the proliferation and invasion of cervical cancer cells by modulating CD36. J Transl Med 2022; 19:531. [PMID: 36008842 PMCID: PMC9413884 DOI: 10.1186/s12967-022-03582-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Accepted: 03/06/2022] [Indexed: 11/12/2022] Open
Abstract
BACKGROUND This study aimed to elucidate the roles of miR-1254 in cervical cancer progression and to explore the underlying mechanisms. METHODS The expression levels of miR-1254 in normal-cancer cervical tissues and cells were measured using quantitive real-time polymerase chain reaction (qRT-PCR). The invasive and proliferative abilities of cervical cancer cell lines transfected with negative control (NC) mimic or miR-1254 mimic were measured using transwell, CCK-8, and colony formation assays. The binding sites between CD36 and miR-1254 were determined using luciferase reporter assays. The correlation of CD36 and miR-1254 with cervical cancer development was re-confirmed by co-transfection of miR-1254 mimic and CD36 overexpression using CCK-8, colony formation, transwell and western blot assays. RESULTS MiR-1254 was expressed at significantly lower levels in the cervical cancer cell lines and tissues than in the controls. The functional assays revealed that upregulation of miR-1254 inhibited the invasion and proliferation of cervical cancer cells. The luciferase reporter assays demonstrated that CD36 messenger RNA and miR-1254 bound to one another. CD36 overexpression reversed the inhibitory effects of upregulated miR-1254 in the cervical cancer cells, suggesting that miR-1254 regulates cervical cancer progression by modulating CD36. CONCLUSION miR-1254 attenuated the invasion and proliferation of cervical cancer cells by modulating the expression levels of CD36.

[PMID: 35929837 PMCID: PMC9417240 DOI: 10.18632/aging.204198] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2021] [Accepted: 07/15/2022] [Indexed: 11/25/2022]
Abstract
Objective: This study aimed to investigate the effects of micro ribonucleic acid (miR)-338-3p on the migration, invasion and proliferation of lung adenocarcinoma (LUAD) cells. Methods: Bioinformatics analysis was employed to evaluate the function and expression of related genes in lung cancer. Human A549 and NCI-H1299 cells cultured to logarithmic growth stage were assigned to negative control (NC) mimic group, miR-338-3p mimic group (miR-mimic group), NC inhibitor group and miR-338-3p inhibitor group (miR-inhibitor group) treated with or without MAP3K2 overexpression (OE)-lentivirus, or TBHQ or FR180204. Transwell assay, cell colony formation assay, Western blotting and cell-cycle analysis were carried out. Results: Bioinformatics results manifested that miR-338 and MAP3K2 were involved in LUAD. The expression levels of MAP3K2, p-ERK1/2, MMP-2, MMP-3, MMP-9, cyclin A2 and cyclin D1 were increased after addition of miR-338-3p inhibitor, consistent with the raised amount of LUAD cells in migration and invasion experiments and number of colonies formed, as well as the cell cycle, but miR-338-3p mimic reversed these results. Moreover, MAP3K2 overexpression elevated the level of p-ERK1/2. Meanwhile, after treatment with TBHQ or FR180204, the influence of miR-338-3p inhibitor or mimic was also verified. Conclusions: MiR-338-3p overexpression can modulate the ERK1/2 signaling pathway by targeting MAP3K2, thus inhibiting the migration, invasion and proliferation of human LUAD cells.

Abstract
Aims As one of the most prevalent malignant diseases in the world, the mechanisms of metastasis in colon cancer are poorly understood. The aim of this study was to investigate the role of the HGF/c-MET axis in the proliferation and metastasis in colon cancer. Methods The effect of MACC1 on cell proliferation and metastasis was analyzed through a series of in vitro experiments. The role of MACC1 in cancer cells was demonstrated by overexpression and silencing of MACC1 in gain or loss function experiments. To investigate the relationship between MACC1 and c-MET/HGF, we detected c-MET protein expression by disrupting with or overexpressing MACC1. The bioinformatics analysis was used to investigate the correlation between MACC1 and c-MET, and the c-MET expression after the interference of HGF with MACC1 was determined. Subsequently, the function of c-MET was verified in colon cancer cells by a series of experiments. The mouse tumor transplantation model experiment is most suitable in vivo. Results The results indicated that the overexpression of MACC1 could accelerate proliferation and facilitate metastasis in colon cancer cell lines. Furthermore, c-MET was determined to be the downstream regulator of MACC1. The addition of HGF could stimulate the expression of MACC1. With further exploration, we proved that c-MET is downstream of MACC1 in colon cancer and that overexpression of c-MET in colon cancer enhances cell proliferation and migration capability. At last, MACC1 expression level negatively correlates with the infiltration levels and several immune checkpoint biomarkers. High MACC1 expression has a lower response rate with ICIs in COAD. Conclusions We found that, under the regulation of the MACC1/HGF/c-MET axis, the proliferation and metastasis of colorectal cancer are increased by MACC1, which can be a novel biomarker for predicting ICIs response in colorectal cancer. Our findings provide a new idea for the targeted treatment of colorectal cancer.

Exosome-Mediated Transfer of miR-1323 from Cancer-Associated Fibroblasts Confers Radioresistance of C33A Cells by Targeting PABPN1 and Activating Wnt/β-Catenin Signaling Pathway in Cervical Cancer. Reprod Sci 2022; 29:1809-1821. [PMID: 35334101 DOI: 10.1007/s43032-021-00820-y] [Citation(s) in RCA: 19] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2020] [Accepted: 12/05/2021] [Indexed: 02/07/2023]
Abstract
Plenty of pieces of evidence suggest that the resistance to radiotherapy greatly influences the therapeutic effect in cervical cancer (CCa). MicroRNAs (miRNAs) have been reported to regulate cellular processes by acting as tumor suppressors or promoters, thereby driving radioresistance or radiosensitivity. Meanwhile, it has been reported that microRNA-1323 (miR-1323) widely participates in cancer progression and radiotherapy effects. However, the role of miR-1323 is still not clear in CCa. Hence, in this study, we are going to investigate the molecular mechanism of miR-1323 in CCa cells. In the beginning, miR-1323 was found aberrantly upregulated in CCa cells via RT-qPCR assay. Functional assays indicated that miR-1323 was transferred by cancer-associated fibroblasts-secreted (CAFs-secreted) exosomes and miR-1323 downregulation suppressed cell proliferation, migration, invasion, and increased cell radiosensitivity in CCa. Mechanism assays demonstrated that miR-1323 targeted poly(A)-binding protein nuclear 1 (PABPN1). Besides, PABPN1 recruited insulin-like growth factor 2 mRNA binding protein 1 (IGF2BP1) to regulate glycogen synthase kinase 3 beta (GSK-3β) and influenced Wnt/β-catenin signaling pathway. Therefore, rescue experiments were implemented to validate that PABPN1 overexpression rescued the inhibited cancer development and radioresistance induced by the miR-1323 inhibitor. In conclusion, miR-1323 was involved in CCa progression and radioresistance which might provide a novel insight for CCa treatment.

Abstract
Globally, lung cancer remains one of the most prevalent malignant cancers. However, molecular mechanisms and functions involved in its pathogenesis have not been clearly elucidated. This study aimed to evaluate the specific regulatory mechanisms of exosomal miR-338-3p/CHL1/MAPK signaling pathway axis in non-small-cell lung cancer. Western blotting and qRT-PCR (reverse transcription-polymerase chain reaction) were used to determine the expression levels of CHL1 and exosomal miR-338-3p in NSCLC (non-small-cell lung cancer). The CHL1 gene was upregulated and downregulated to evaluate its functions in NSCLC progression. In vitro MTS and apoptotic assays were used to investigate the functions of CHL1 and exosomal miR-338-3p in NSCLC progression. The high-throughput sequencing was used to explore differently expressed exosomal miRNAs. The biological relationships between MAPK signaling pathway and CHL1 and exosomal miR-338-3p in NSCLC were predicted through bioinformatics analyses and verified by western blotting. Elevated CHL1 levels were observed in NSCLC tissues and cells. Upregulated CHL1 expression enhanced NSCLC cells’ progression by promoting tumor cells proliferation while suppressing their apoptosis. Conversely, the downregulation of the CHL1 gene inhibited NSCLC cells’ growth and promoted tumor cells’ apoptotic rate. Additionally, CHL1 activated the MAPK signaling pathway. Besides, we confirmed that miR-338-3p directly sponged with CHL1 to mediate tumor cells progression. Moreover, exosomal miR-338-3p serum levels in NSCLC patients were found to be low. BEAS-2B cells can transfer exosomal miR-338-3p to A549 cells and SK-MES-1 cells. In addition, elevated exosomal miR-338-3p levels significantly inhibited tumor cells proliferation and promoted their apoptosis by suppressing activation of the MAPK signaling pathway. Exosomal miR-338-3p suppresses tumor cells' metastasis by downregulating the expression of CHL1 through MAPK signaling pathway inactivation.

Abstract
Emerging evidence reveals that long noncoding RNAs (lncRNAs) contribute to human tumorigenesis. Nevertheless, the function of HOXC cluster antisense RNA 3 (HOXC-AS3) in human cervical cancer (CC) remains largely unknown. The levels of HOXC-AS3, miR-105-5p and SOS1 in CC tissues and cells were monitored by reverse transcription-polymerase chain reaction (RT-PCR) and western blot (WB). Gain- and loss-of-function experiments were conducted to verify the function of HOXC-AS3 and miR-105-5p in CC cells. Meanwhile, cell proliferation, apoptosis, migration and invasion were examined by the cell counting kit-8 (CCK8) experiment, colony formation assay, flow cytometry and Transwell assay. Dual-luciferase reporter assay and RNA immunoprecipitation (RIP) assay were carried out to test the regulatory interaction of HOXC-AS3, miR-105-5p and SOS1. In addition, in vivo experiment was performed to certain the role of HOXC-AS3 in tumorigenesis of CC. HOXC-AS3 was overexpressed in CC tissues (vs. adjacent normal tissues) and CC cells. Besides, the higher HOXC-AS3 profile was associated with the poorer clinical prognosis of CC patients. Overexpression of HOXC-AS3 promoted cell growth, migration and invasion, hampered apoptosis, whereas knocking down HOXC-AS3 exhibited the reverse effects. MiR-105-5p was a downstream target of HOXC-AS3, and it mediated the HOXC-AS3-induced oncogenic effects. Mechanistically, the bioinformatic analysis illustrated that SOS1 was targeted by miR-105-5p. Up-regulating SOS1 heightened the growth, migration and invasion of CC cells by enhancing the ErbB signaling pathway, which was reversed by miR-105-5p. Up-regulated HOXC-AS3 aggravates CC by promoting SOS1 expression via targeting miR-105-5p.

Abstract
Cervical cancer (CC) is a type of gynecological malignancy that poses a significant threat to females. The aim of the present study was to examine the role of long intergenic non-protein coding RNA 1123 (LINC01123) and its underlying molecular mechanism in the development of CC. mRNA expression levels of LINC01123 and microRNA (miR)-361-3p in CC tissue samples and cell lines were evaluated using reverse transcription-quantitative PCR. Cell viability, migration and invasion were detected using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, wound healing and Transwell assays. Moreover, a xenograft tumor model was established for elucidating the influence of LINC01123 knockdown on tumor growth in vivo. A dual-luciferase reporter assay was used to confirm the association between LINC01123 and miR-361-3p, and miR-361-3p and tetraspanin 1 (TSPAN1). Western blot analysis was used to determine TSPAN1 protein expression. LINC01123 expression was upregulated and miR-361-3p expression was reduced in CC tissue samples and cell lines. Knockdown of LINC01123 inhibited cell viability, migration and invasion in vitro, and suppressed tumor growth in vivo. Furthermore, LINC01123 targeted miR-361-3p and negatively regulated miR-361-3p expression. Overexpression of miR-361-3p inhibited cell viability, migration and invasion in HeLa and CaSki cells. Additionally, miR-361-3p targeted TSPAN1 and negatively regulated TSPAN1 expression. Inhibition of miR-361-3p and overexpression of TSPAN1 reversed the effect of LINC01123 knockdown on cell proliferation, migration and invasion in HeLa cells. Knockdown of LINC01123 inhibited cell proliferation, migration and invasion via miR-361-3p/TSPAN1 regulation in CC, which may present an effective target for treatment of CC.

Abstract
Cervical cancer is associated with infection by certain types of human papillomaviruses (HPVs), and this affects women worldwide. Despite the improvements in prevention and cure of HPV-induced cervical cancer, it remains the second most common type of cancer in women in the least developed regions of the world. Epigenetic modifications are stable long-term changes that occur in the DNA, and are part of a natural evolutionary process of necessary adaptations to the environment. They do not result in changes in the DNA sequence, but do affect gene expression and genomic stability. Epigenetic changes are important in several biological processes. The effects of the environment on gene expression can contribute to the development of numerous diseases. Epigenetic modifications may serve a critical role in cancer cells, by silencing tumor suppressor genes, activating oncogenes, and exacerbating defects in DNA repair mechanisms. Although cervical cancer is directly related to a persistent high-risk HPV infection, several epigenetic changes have been identified in both the viral DNA and the genome of the infected cells: DNA methylation, histone modification and gene silencing by non-coding RNAs, which initiate and sustain epigenetic changes. In the present review, recent advances in the role of epigenetic changes in cervical cancer are summarized.

Abstract
Background Cancer, as one of the main causes of human deaths, is currently a significant global health challenge. Since the majority of cancer-related deaths are associated with late diagnosis, it is necessary to develop minimally invasive early detection markers to manage and reduce mortality rates. MicroRNAs (miRNAs), as highly conserved non-coding RNAs, target the specific mRNAs which are involved in regulation of various fundamental cellular processes such as cell proliferation, death, and signaling pathways. MiRNAs can also be regulated by long non-coding RNAs (lncRNAs) and circular RNAs (circRNAs). They are highly stable in body fluids and have tumor-specific expression profiles, which suggest their suitability as efficient non-invasive diagnostic and prognostic tumor markers. Aberrant expression of miR-338 has been widely reported in different cancers. It regulates cell proliferation, migration, angiogenesis, and apoptosis in tumor cells. Main body In the present review, we have summarized all miR-338 interactions with other non-coding RNAs (ncRNAs) and associated signaling pathways to clarify the role of miR-338 during tumor progression. Conclusions It was concluded that miR-338 mainly functions as a tumor suppressor in different cancers. There were also significant associations between miR-338 and other ncRNAs in tumor cells. Moreover, miR-338 has a pivotal role during tumor progression using the regulation of WNT, MAPK, and PI3K/AKT signaling pathways. This review highlights miR-338 as a pivotal ncRNA in biology of tumor cells.

Abstract
Cervical cancer is one of the leading causes of cancer-related death among women, which is attributed partly by limited treatment options. Recent studies have provided in-depth explanations regarding the role of circular RNA in cancers. We aimed to investigate the role of circular RNA_0000326 in cervical cancer. Bioinformatics analysis revealed a high circ_0000326 expression in cervical cancer. Cervical cancer cells and tissues were also observed to have elevated levels of circ_0000326 and the upregulation of circ_0000326 depended on the stage of cancer. Transfection with siRNA of circ_0000326 resulted in the inhibition of proliferation, migration and cell cycle of cancer cells. Interestingly, we confirmed that circ_0000326 served as a sponge for microRNA-338-3p and that the miRNA bound to Cyclin-dependent kinase 4. In the presence of microRNA-338-3p mimic or silencing of circ_0000326, Cyclin-dependent kinase 4 expression was decreased. Transfection with microRNA-338-3p mimic inhibited cell clone formation and proliferation. Moreover, in vivo experiment revealed that the injection of shRNA-circ_0000326 lentivirus suppressed tumor growth and decreased Cyclin-dependent kinase 4 expression. Taken altogether, our results showed that circ_0000326 exerted oncogenic effects on cervical cancer by upregulating Cyclin-dependent kinase 4 via sponging microRNA-338-3p. This systematic investigation on circ_0000326 could provide further insight into cervical cancer.

Abstract
Dysregulations in transcription factors (TFs) and their genetic products play important roles in tumorigenesis, tumor progression and metastasis. However, prognostic value of the transcriptional regulatory networks in different cancers has not been investigated in depth. The purpose of our study was to identify and validate a potential predictive signature that combines TFs and their regulatory products in eight solid tumors. We used bioinformatics analysis to identify MET Transcriptional Regulator (MACC1) and Serine Peptidase Inhibitor Kunitz Type 1 (SPINT1) as candidate TFs with the respective downstream regulatory proteins for patient prognosis in pan‐cancer. Subsequent molecular analysis of clinical gastric cancer tissue samples further verified the negative correlation between MACC1 and SPINT1. Further, we showed that mechanistically, MACC1/SPINT1 mediated the pro‐HGF proteolysis and c‐Met phosphorylation in HGF/c‐MET signaling pathway. Kaplan‐Meier plots and receiver operating characteristics analysis revealed that the two‐gene signature combining MACC1 with SPINT1 was effective in predicting survival in all eight cancer cohorts tested. In conclusion, our study clarified the regulatory relationship between MACC1 and SPINT1 in the context of the HGF/c‐MET signaling pathway and determined MACC1/SPINT1 panel as a valuable signature for the prediction of prognosis in patients for multiple solid cancer types.

Cancer Manag Res 2021; 13:1435-1447. [PMID: 33603486 PMCID: PMC7886091 DOI: 10.2147/cmar.s291778] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2020] [Accepted: 01/13/2021] [Indexed: 12/24/2022] Open
Abstract
Purpose Long intergenic non-protein coding RNA 885 (LINC00885) has been well studied in breast cancer; however, its contribution in cervical cancer remains unclear. In this study, we aimed to determine the detailed functions of LINC00885 in cervical cancer and elucidate the underlying molecular regulation mechanism. Methods The expression status of LINC00885 in cervical cancer was determined using reverse transcription-quantitative polymerase chain reaction and by searching The Cancer Genome Atlas database. The detailed functions of LINC00885 in cervical cancer cells were confirmed using Cell Counting Kit 8 assay, flow cytometry analysis, Transwell cell migration and invasion assays, and tumor xenograft assay. Mechanistic experiments included bioinformatics prediction, RNA immunoprecipitation, luciferase reporter assay, and rescue experiments. Results LINC00885 was clearly overexpressed in cervical cancer, which was linked with unfavorable clinical outcomes. Functionally, LINC00885 deficiency suppressed cervical cancer cell proliferation, migration, and invasion but stimulated cell apoptosis in vitro. Furthermore, loss of LINC00885 restricted the growth of cervical cancer cells in vivo. Mechanistically, LINC00885 functioned as a competitive endogenous RNA for microRNA-432-5p (miR-432-5p) in cervical cancer. Furthermore, metastasis-associated colon cancer 1 (MACC1) was confirmed as the direct target of miR-432-5p, and LINC00885 could enhance MACC1 expression by sequestering miR-432-5p. Rescue experiments revealed that silencing of miR-432-5p or upregulation of MACC1 expression could effectively counteract the restrained aggressive properties of cervical cancer cells induced by LINC00885 deficiency. Conclusion LINC00885 upregulated MACC1 expression in cervical cancer cells by sponging miR-432-5p, thereby promoting cancer progression. The LINC00885/miR-432-5p/MACC1 pathway may help in the identification of potential prognostic biomarkers and therapeutic targets in cervical cancer.

Abstract
The main characteristics of cervical cancer are abnormal and uncontrolled cell proliferation, and it regulates cell growth, differentiation, and cell death through genetic and epigenetic changes. This paper mainly discusses the radiosensitivity of the cervical cancer protein kinase B signaling pathway and discusses the specific mechanisms that affect the occurrence and development of cervical cancer. In addition, this paper studies the effect of transient transfection knocking down the expression of TRIP4 in cervical cancer cells on the expression of key proteins in related signaling pathways and explores the mechanism of its specific effects and finds the mechanism of TRIP4's effect on cervical cancer radiosensitivity. The findings of this study show for the first time that knocking down TRIP4 inhibits cell viability by inhibiting the P13K/AKT and MAPK/ERK pathways, and this corresponds to the first part of the experimental results, which show that knocking down TRIP4 inhibits colony formation and increases apoptosis in HeLa and SiHa cells. Moreover, simultaneous inhibition of TRIP4 and hTERT proteins can increase the radiosensitivity of cervical cancer cells. These findings indicate that the inhibition of TRIP4 may be a new type of treatment that selectively targets the P13K/AKT and MAPK/ERK pathways and hTERT pathways in cervical cancer cells and provides a therapeutic option for the treatment of cervical cancer.

Abstract
Background Cervical cancer (CC) is the one of most common malignant gynecological tumors, which is characterized with the high mortality and recurrence rate. Previous studies have elucidated the oncogenic role of small nucleolar RNA host gene 6 (SNHG6) in some types of human cancers, whereas it is unclear whether it functions as an oncogene in CC. This study was aimed at unveiling the role of SNHG6 in CC. Methods qRT-PCR analysis was implemented to evaluate the expression levels of SNHG6, miR-485-3p and STYX in CC cells. RNA pull down assay and luciferase reporter assay were conducted to verify the interaction between miR-485-3p and SNHG6 or STYX. Functional assays, such as colony formation assay, JC-1 assay and TUNEL assay were applied to detect the biological behaviors of CC cells. The resistance of CC cells to radiation was evaluated by colony formation assay. Results SNHG6 was expressed at a high level in CC cells. Silenced SNHG6 suppressed cell proliferation but promoted cell apoptosis. Additionally, silenced SNHG6 could sensitize CC cells to radiation treatment. miR-485-3p could bind to both SNHG6 and STYX. Knockdown of miR-485-3p or overexpression of STYX could abolish the effects of SNHG6 silencing on CC cell growth. Conclusions LncRNA SNHG6 enhances the radioresistance of CC cells and promotes CC cell growth by sponging miR-485-3p to release STYX.

Abstract
Objective MicroRNAs (miRNAs) are highly involved in cancer development, including in cervical cancer (CC). In this study, we aimed to investigate the role and possible mechanism of a poorly studied miRNA, miR-1193, in CC progression. Materials and Methods Expression of miR-1193 was determined in 60 pairs of cervical samples. The impacts of miR-1193 on CC cell proliferation, invasion and migration capacities were verified by CCK-8, transwell and wound healing assays, respectively. Then, bioinformatics prediction, luciferase reporter assay, qRT-PCR and Western blot were successively conducted to study the targeting of claudin 7 (CLDN7) by miR-1193. After CLDN7 was restored in miR-1193-overexpressed cells, the rescue effects were determined. Finally, CLDN7 expression was analyzed in cervical samples, and its expression correlation with miR-1193 was explored. Results Compared with paired normal tissues, miR-1193 was sharply decreased in abnormal tissues (intraepithelial lesions and cancerous tissues). Especially, miR-1193 expression was gradually decreased in low-grade squamous intraepithelial lesions, high-grade squamous intraepithelial lesions and CC. Enforced expression of miR-1193 inhibited CC cell proliferation, invasion and migration. Mechanistically, we confirmed CLDN7 as a target of miR-1193, and restoration of CLDN7 robustly rescued the tumor suppressing effects of miR-1193 in CC cells. CLDN7 was upregulated in abnormal cervical tissues and its expression exhibited inverse correlation with that of miR-1193 in CC. Conclusion Our results suggested that miR-1193 exerted tumor inhibitory roles in CC malignancy by directly targeting CLDN7.

Abstract
The present study aimed to investigate the role of miR-338-3p in pregnancy-induced hypertension (PIH), and its effects on human trophoblast cells in vitro. Quantitative real-time PCR was used to detect miR-338-3p expression. Human trophoblast HTR8/SVneo cells were transfected with miR-338-3p mimics. Effects of miR-338-3p on cell proliferation, invasion and metastasis, and anoikis resistance were detected by CCK-8 assay, Transwell chamber assay, flow cytometry and western blot analysis, respectively. Bioinformatics analysis was performed to predict the target of miR-338-3p, and the results were confirmed by dual luciferase reporter assay. The expression level of miR-338-3p was significantly upregulated in the peripheral blood and placenta of PIH patients. CCK-8 assay showed that miR-338-3p mimics inhibited the proliferation of HTR8/SVneo cells at indicated time points. Flow cytometry showed that miR-338-3p transfection significantly increased the Ki-67 expression in the HTR8/SVneo cells, indicating enhanced cell proliferation. Transwell chamber assay and western blot analysis showed that the invasion and metastatic abilities of the HTR8/SVneo cells were significantly decreased in the miR-338-3p transfection group, as well as expression levels of MMP-2 and MMP-9. Bioinformatics analysis and dual luciferase reporter assay indicated that AKT3 is a target gene of miR-338-3p. Our results suggest that miR-338-3p is significantly increased in the peripheral blood and placenta of PIH patients, which is correlated with the disease development. miR-338-3p inhibits proliferation, invasion and metastasis, and apoptosis resistance of human trophoblast cells by targeting AKT3.

Abstract
BACKGROUND Brain-derived neurotrophic factor (BDNF) and microRNA (miRNA) play crucial roles in the etiology of depression. However, the molecular mechanisms underlying this disease are not fully understood. The primary objective of this study was to investigate the relationship between miR-202-3p and BDNF in a chronic unpredictable mild stress (CUMS) model. METHODS Depression model was established with chronic mild unpredictable mild stimulation (CUMS) combined with solitary feeding. The expression levels of miR-202-3p and BDNF in rat hippocampus were measured by qRT-PCR. The novelty inhibition feeding test (NSFT), sucrose preference test (SPT), and forced swimming test (FST) were used to evaluate the functions of miR-202-3p and BDNF. Target gene prediction and screening and luciferase reporter assay were used to verify the target of miR-202-3p. The expression levels of BNDF, CREB1 and p-CREB1 were detected by Western blot. RESULTS Upregulation of miR-202-3p was associated with decreased expression of BDNF in the hippocampus of the CUMS model. Antidepressant was observed when LV-BDNF or LV-si-miR-202-3p was injected into the hippocampus. In addition, in the rat hippocampus and cultured nerve cells, the expression levels of BDNF and cyclic AMP response element binding protein 1 (CREB1), which is a target gene of BDNF, were reduced after LV-miR-202-3p injection. Overexpression of miR-202-3p aggravated depressive behavior and decreased the expression levels of BDNF. Luciferase reporter assay also confirmed that BDNF was a target of miR-202-3p. CONCLUSION Silencing miR-202-3p can reduce the damage to hippocampal nerve in CUMS rats; the mechanism may be related to the upregulation of BNDF expression. miR-202-3p may be an effective target for the treatment of depression.

Abstract
Background The carcinogenesis and progression of cervical cancer is a complex process in which numerous microRNAs are involved. The purpose of this study is to investigate the role of miR-125a-5p in progression of cervical cancer. Methods RT-qPCR was used to detect the expression of miR-125a-5p and GALNT7 in cervical cancer tissues and cell lines. Then, the miR-125a-5p mimic, miR-125a-5p inhibitor, GALNT7 siRNA, or/and pcDNA-GALNT7 were respectively transfected into HeLa and Caski cervical cancer cells, and Cell Counting kit-8 assay, Transwell assay and flow cytometry analysis were respectively used to observe cell proliferation, invasion and apoptosis. Subsequently, luciferase reporter gene assay was employed in confirming the target relationship between miR-125a-5p and GALNT7. MiR-125a-5p mimic or/and pcDNA-GALNT7 were transfected into the cervical cancer cells at the absence of epidermal growth factor (EGF) or not, and the pcDNA-GALNT7 was transfected into the cervical cancer cells at the absence of inhibitors of multiple kinases or not. Furthermore, the effect of miR-125a-5p on tumor growth was also studied using a xenograft model of nude mice. Results MiR-125a-5p was down-regulated in both cervical cancer tissues and cell lines and it inhibited cell proliferation and invasion of cervical cancer cells. MiR-125a-5p directly targeted and post-transcriptionally downregulated GALNT7 that was strongly upregulated in cervical cancer tissues and cell lines. Similar to the effect of miR-125a-5p mimic, silencing GALNT7 inhibited proliferation and invasion of cervical cancer cells. In addition, miR-125a-5p overexpression could counteract both GALNT7- and EGF-induced cell proliferation and invasion. GALNT7 promoted cell proliferation and invasion by activating the EGFR/PI3K/AKT kinase pathway, which could be abated by the inhibitors of the kinases. Moreover, the role of miR-125a-5p inhibited tumor formation in cervical cancer by suppressing the expression of GALNT7 in vivo. Conclusion In conclusion, miR-125a-5p suppressed cervical cancer progression by post-transcriptionally downregulating GALNT7 and inactivating the EGFR/PI3K/AKT pathway.

Apoptosis was evaluated by flow cytometry and alterations of apoptosis-related genes. The effect of miR-499a-5p on epithelial-mesenchymal transition (EMT) was examined by determining the protein levels of EMT-associated genes. Then, colony formation assay was used to determine the radiosensitivity of CC cells. A dual-luciferase reporter assay was performed to confirm the direct target of miR-499a-5p. Results MiR-499a-5p was significantly downregulated in CC tissues and cell lines. Overexpression of miR-499a-5p or eIF4E knockdown markedly inhibited cell proliferation, invasion, migration, and EMT, and enhanced apoptosis. eIF4E was predicted and verified as a target gene of miR-499a-5p. The influence of miR-499a-5p upregulation on proliferation, apoptosis, invasion, migration, EMT, and radiosensitivity was abrogated by eIF4E overexpression. Discussion MiR-499a-5p promoted the apoptosis and radiosensitivity and inhibited proliferation, invasion, migration, and EMT by directly targeting eIF4E in CC cells.

Abstract
Objective MicroRNA (miR)-147a acts as an inhibitory miRNA in many cancers. However, its potential roles in non-small-cell lung cancer (NSCLC) remain unclear. Methods Levels of miR-147a and C-C motif chemokine ligand 5 (CCL5) were measured using a quantitative real-time PCR assay. Cell growth, migration, and invasion of NSCLC cells were assessed by colony formation, wound healing, and Transwell invasion assays, respectively. The role of miR-147a in the growth and metastatic ability of NSCLC in vivo was detected using a xenograft model and experimental lung metastasis model. Results miR-147a was downregulated in NSCLC cell lines as well as in tissues. Gain-of-function and loss-of-function analyses demonstrated that upregulation of miR-147a decreased the aggressiveness of NSCLC cells in vitro. In addition, CCL5 was identified as a target of miR-147a. We also demonstrated the effect of miR-147a in the progression of NSCLC cells via targeting CCL5. Finally, the in vivo mouse xenograft model showed that miR-147a inhibited progression of NSCLC cells. Conclusions Overall, expression of miR-147a was downregulated in NSCLC. Importantly, upregulation of miR-147a suppressed the growth and metastasis of NSCLC cells in vivo by targeting CCL5.

Abstract
BACKGROUND Downregulation of microRNA-338-3p (miR-338-3p) was detected in many malignant tumors, which indicated miR-338-3p might serve as a role of antioncogene in those cancers. The present study aimed to explore the roles of miR-338-3p in the growth and metastasis of ovarian cancer cells and elaborate the underlying possible molecular mechanism. METHODS Multiply biomedical databases query and KEGG pathway enrichment assay were used to infilter possible target genes and downstream pathways regulated by miR-338-3p. Overexpression miR-338-3p lentiviral vectors were transfected into ovarian cancer OVCAR-3 and OVCAR-8 cells, cell proliferation, migration and invasion were analyzed by MTT, colony formation, transwell, Matrigel assay and xenograft mouse model. One 3'-untranslated regions (UTRs) binding target gene of miR-338-3p, MACC1 (MET transcriptional regulator MACC1), and its regulated gene MET and downstream signaling pathway activities were examined by western blot. RESULTS Biomedical databases query indicated that miR-338-3p could target MACC1 gene and regulate Met, downstream Wnt/Catenin beta and MEK/ERK pathways. Rescue of miR-338-3p could inhibit the proliferation, migration and invasion of ovarian cancer cells, and suppress the growth and metastasis of xenograft tumor. Restoration of miR-338-3p could attenuate MACC1 and Met overexpression induced growth, epithelial to mesenchymal transition (EMT) and activities of Wnt/Catenin beta and MEK/ERK signaling in vitro and in vivo. CONCLUSIONS The present data indicated that restoration of miR-338-3p could suppress the growth and metastasis of ovarian cancer cells, which might due to the inhibition of proliferation and EMT induced by MACC1, Met and its downstream Wnt/Catenin beta and MEK/ERK signaling pathways.

Exp Ther Med 2019; 18:3650-3658. [PMID: 31602243 DOI: 10.3892/etm.2019.7989] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2018] [Accepted: 08/02/2019] [Indexed: 12/13/2022] Open
Abstract
Previously, a number of microRNAs (miRNAs) have been reported to be dysregulated in cervical cancer, and dysregulated miRNAs may play crucial roles in the development and progression of cervical cancer. Hence, investigating the detailed roles of miRNAs that are aberrantly expressed in cervical cancer and the underlying molecular mechanisms is essential for early diagnosis and effective therapeutic approaches. miRNA-877 (miR-877) was found to be downregulated in hepatocellular carcinoma and renal cell carcinoma, and function as a tumor-suppressive miRNA. However, how miR-877 exerts an effect in cervical cancer progression and its underlying molecular mechanisms remains to be elucidated. In the current study, reverse transcription-quantitative PCR was performed to determine miR-877 expression in cervical cancer tissues and cell lines. The effects of miR-877 overexpression on cervical cancer cell proliferation and invasion were evaluated using MTT and Transwell cell invasion assays. In the present study, miR-877 was significantly downregulated in cervical cancer tissues and cell lines, and the decreased expression levels of miR-877 were significantly associated with increased International Federation of Gynecology and Obstetric stage as well as increased lymph node metastasis in patients with cervical cancer. Upregulation of miR-877 using miR-877 mimics resulted in the decreased proliferation and invasion of cervical cancer cells. Metastasis-associated in colon cancer-1 (MACC1) was assessed using bioinformatics analyses to determine whether it could be a potential target gene of miR-877, and the results were confirmed using a luciferase reporter assay. Furthermore, MACC1 was markedly upregulated in cervical cancer tissues, and its level was negatively correlated with the miR-877 level. Overexpression of miR-877 resulted in decreased expression levels of MACC1 in cervical cancer cells at both the mRNA and protein levels. In addition, the functional effects of MACC1 knockdown were similar to those induced by upregulated miR-877 in cervical cancer cells. MACC1 restored miR-877 overexpression-mediated suppression of cervical cancer cell proliferation and invasion. In conclusion, miR-877 may play an antitumor role in cervical cancer by directly targeting MACC1, which suggests that this miRNA may be a promising therapeutic target for the treatment of patients with such an aggressive gynecological cancer.

Abstract
The aim of the present study was to identify predictive factors for cervical cancer (CC) progression using a multistage approach. The present study obtained data from 390 healthy women and 259 patients with cervical cancer between June 2012 and June 2017, and used a multiple stage re-analysis strategy for clinical detection of CC. A total of seven types of serum indices were used in the present study, including sugar chain antigen 125 (CA-125), sugar chain antigen 199 (CA-199), α fetoprotein (AFP), carcino- embryonic antigen, alkaline phosphatase (ALP), cholesterol and triglyceride (TG). The expression levels of CA-125, CA-199, AFP, ALP, cholesterol and TG were significantly different between healthy women and patients with cervical squamous cell carcinoma (SCC). Furthermore, ALP, cholesterol and TG expression levels were significantly different in healthy women compared with patients with cervical adenocarcinoma (AC). Further comparisons based on age and pathological staging demonstrated that the variability in the ALP level was not significant between the <40 years old age group and the 40-50 years old age group within healthy individuals (P>0.05); however, was significant in patients with SCC (P<0.05). Staging analysis identified significant differences in ALP between healthy women and patients with SCC (Stage I-IV), and significant differences between healthy women and patients with Stage I AC. The results of the present study indicated that the expression of ALP was significantly increased in patients with CC compared with healthy women. Therefore, ALP may be a potential predictive factor for the development of CC.

J Cancer 2019; 10:1385-1392. [PMID: 31031848 PMCID: PMC6485222 DOI: 10.7150/jca.29502] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2018] [Accepted: 01/16/2019] [Indexed: 12/12/2022] Open
Abstract
Objective To detect the expression of microRNA-338-3p (miR-338-3p) and MET transcriptional regulator MACC1 (MACC1) gene in different ovarian tissues, to analyze their relationships, their correlations to the clinicopathologic characteristics of epithelial ovarian cancer and their significant to the progression of ovarian cancer. Methods The expression of miR-338-3p and MACC1 gene in 20 specimens of normal ovarian tissues, 20 specimens of benign epithelial ovarian tumor and 65 specimens of epithelial ovarian cancer was detected by real-time PCR method. Their interrelationships and their correlations to the clinicopathologic characteristics of epithelial ovarian cancer were analyzed. Risk factors of recurrence and death were discussed by binary Logistic regression analysis. The relations between miR-338-3p and MACC1 expression and the survival of ovarian cancer were measured by Kaplan-Meier analysis. Results The expressions of miR-338-3p and MACC1 gene in epithelial ovarian cancer tissues were (0.331±0.038) and (0.774±0.025), significant differences were noted between epithelial ovarian cancer and normal ovarian tissues, benign ovarian tumors (F=77.916, P=1.205E-18; F=77.945, P=1.187E-18). In different ovarian tissues, miR-338-3p expression was negatively correlated to MACC1 expression (r = -0.968, P<0.0001). In epithelial ovarian cancer, lower expression of miR-338-3p and higher expression of MACC1 were associated with more advanced FIGO stage, higher histological grade and developed lymph node metastasis. Down-regulation of miR-338-3p was related with the recurrence (P=0. 005, OR=12.862, 95%CI: 2.120~78.026) and death (P=0. 007, OR=12.837, 95%CI: 2.205~81.389) of ovarian cancer patients, which was showed by binary Logistic regression analysis. Compared to other patients, the overall survival rate and progression free survival rate of patients with lower miR-338-3p and higher MACC1 expression were obviously poorer (χ2=16.955, P=7.219E-5; χ2=18.929, P=2.828E-5). Conclusions Down-regulation of miR-338-3p and up-regulation of MACC1 gene were closely related with the poor prognosis of epithelial ovarian cancer patients, which could served as bio-markers of the progression and recurrence of ovarian cancer.

Abstract
The mortality and incidence rates of colorectal cancer (CRC) vary widely worldwide. miR-338-3p inhibits tumor cell proliferation in several types of cancer, however, the role of miR-338-3p on CRC remains unknown. The aim of the current study was to investigate the cellular function of miRNA-338-3p (miR-338-3p) in CRC, the malignant behavior of CRC cells and the interaction between miR-338-3p and metastasis-associated in colon cancer-1 (MACC1). miR-338-3p expression was significantly decreased in CRC tissue compared with adjacent normal tissue. In the CRC cell line SW480, miR-338-3p overexpression suppressed cell proliferation and migration and induced G1/S cell cycle arrest and apoptosis. By contrast, miR-338-3p knockdown significantly enhanced cell proliferation and migration, and suppressed G1/S cell cycle arrest and apoptosis. Furthermore, the dual-luciferase reporter assay confirmed MACC1 as a direct target of miR-338-3p. In addition, miR-338-3p overexpression reduced the level of MACC1 protein expression and MACC1 expression was significantly upregulated in CRC tissue samples. MACC1 siRNA significantly reduced CRC cell proliferation and migration, whilst cell apoptosis was significantly increased. In conclusion, miR-338-3p expression was decreased in CRC. miR-338-3p regulated the proliferation, apoptosis and migration of CRC cells by targeting MACC1.

Abstract
Background The inhibitor of apoptosis, B-cell lymphoma 2 (Bcl-2), is encoded by the BCL2 gene. Previous studies have shown that microRNAs are downregulated in prostate cancer. This study aimed to investigate the role of microRNA-205 and microRNA-338-3p and cell apoptosis in prostate carcinoma tissue and the LNCaP human prostate adenocarcinoma cell line by directly targeting the BCL2 gene and Bcl-2 protein expression. Material/Methods Bioinformatics methods predicted the target genes of miR-205 and miR-338-3p, which were validated by a luciferase assay. Immunohistochemistry was used to detect Bcl-2 protein expression in 30 samples of prostate carcinoma tissue and 30 matched samples of normal prostate. The normal prostate epithelial cell line, RWPE-1, and LNCaP human prostate adenocarcinoma cells studied in vitro. BCL2 mRNA expression and Bcl-2 protein expression were determined by quantitative polymerase chain reaction (q-PCR) and Western blot, respectively. Cell apoptosis was measured by flow cytometry using annexin V, fluorescein isothiocyanate, and phycoerythrin (annexin V-FITC/PE). Results TargetScan Human 7.2 predicted that the structures of miR-205 and miR-338-3p had a binding site on the proto-oncogene, BCL2, which was verified by a luciferase assay. The expression of miR-205 and miR-338-3p were significantly downregulated in prostate carcinoma tissues and LNCaP cells when compared with normal controls. BCL2 expression was significantly inhibited by overexpression of miR-205 and miR-338-3p in LNCaP cells. Conclusions The results of this study showed that miR-205 and miR-338-3p downregulated the expression of the BCL2 gene and decreased apoptosis in prostate carcinoma.

Background The purpose of this study is to explore the potential biological roles of miR-101-5p in the progression of non-small-cell lung carcinoma (NSCLC). Methods The levels of miR-101-5p and chemokine (C-X-C motif) ligand 6 (CXCL6) in NSCLC tissues and cells were detected using the quantitative real-time PCR (qRT-PCR) assay. Proliferation, colony formation, migration and invasion assays were conducted using miR-101-5p-transfected NSCLC cells in vitro. The expression of CXCL6 was measured using immunofluorescence assay. Xenograft model and lung metastasis model were constructed to further reveal the precise roles of miR-101-5p in the lung metastasis and growth of NSCLC cells in vivo. Results miR-101-5p was underregulated in NSCLC tissues when compared with that in the normal controls. The levels of miR-101-5p were lower in NSCLC cells (H1975, A549, HCC827 and H1650) than in non-tumorigenic human bronchial epithelial cells (BEAS-2B). Overregulation of miR-101-5p restrained the aggressiveness phenotypes of NSCLC cells in vitro. Furthermore, overregulation of miR-101-5p reduced the tumor growth and pulmonary metastasis of NSCLC cells in vivo. CXCL6 was the target gene of miR-101-5p in NSCLC. The mRNA levels of CXCL6 were negatively associated with the levels of miR-101-5p in NSCLC tissues. Finally, the rescue experiments suggested that the inhibitory role of miR-101-5p was mediated by regulating the expression of CXCL6 in NSCLC. Conclusion These findings indicated that overregulation of miR-101-5p restrained the progression of NSCLC cells by targeting CXCL6 and might function as a potential therapeutic target for NSCLC.

Abstract
Background MicroRNA-217 (miR-217) has been demonstrated to participate in the tumorigenesis and progression of various types of cancers. Nevertheless, the role of miR-217 in cervical carcinoma still remains not fully elucidated. This current work sought to investigate the role of miR-217 in the growth, migration, and invasion of cervical carcinoma and detect the role of miR-217 in the chemosensitivity of cervical carcinoma cell to cisplatin. Materials and methods The levels of miR-217 in 65 pairs of cervical carcinoma tissues and matched normal tissues were detected using quantitative real-time-PCR assay. The roles of miR-217 on the growth, apoptosis, migration, and invasion of cervical cancer SiHa and Ca-Ski cells were analyzed using Cell Counting Kit-8, flow cytometry, wound healing, and Transwell invasion assays, respectively. The target of miR-217 was identified using the online analysis tool TargetScan (http://www.targetscan.org/vert_72/) and was verified by luciferase reporter and immunoblotting assays. The xenograft tumor model was constructed to explore the impact of miR-217 on the growth of cervical carcinoma cell in vivo. Results The level of miR-217 was remarkably lower in cervical carcinoma tissues than that in noncancerous tissues. Overregulation of miR-217 markedly suppressed the aggressiveness of cervical cancer cell and induced cell apoptosis through regulating V-Ki-Ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS). Finally, upregulation of miR-217 enhanced the chemosensitivity of both SiHa and Ca-Ski cervical cancer cells toward cisplatin. Conclusion Altogether, upregulation of miR-217 inhibits the aggressiveness phenotypes of cervical carcinoma cell via regulating KRAS gene and increases the sensitivity of cervical cancer cell to cisplatin.

Abstract
BACKGROUND Colorectal cancer (CRC) is one the leading causes of cancer related deaths among Iranians. Despite the various progresses in new therapeutic methods, it has still a low rate of survival. This high ratio of mortality is mainly related to the late diagnosis, in which the patients refer for treatment in advanced stages of tumor. MAIN BODY: colorectal cancer progression is largely associated with molecular and genetic bases. Although Iran has a high ratio of CRC mortality, there is not an efficient genetic panel for detection and prognosis. Therefore, it is critical to introduce new diagnostic markers with ability to detect in early stages. CONCLUSION Present review summarizes all of the genetic and epigenetic factors which are reported in CRC until now among the Iranian patients to pave the way of incorporation of new ethnic specific markers into the clinical practice and development of new targeted therapeutic methods.

Abstract
Background and aim Previous studies have suggested that lymph node metastasis (LNM) in early-stage cervical cancer (CESC) may affect the prognosis of patients and the outcomes of subsequent adjuvant therapy. However, research focused on miRNA expression in early-stage CESC patients with LNM remains limited. Therefore, it is necessary to identify prognostic miRNAs and determine their molecular mechanisms. Methods We evaluated the differentially expressed genes in early-stage CESC patients with LNM compared to patients without LNM and evaluated the prognostic significance of these differentially expressed genes by analyzing a public dataset from The Cancer Genome Atlas. Potential molecular mechanisms were investigated by gene ontology, the Kyoto Encyclopedia of Genes and Genomes, and protein–protein interaction network analyses. Results According to the The Cancer Genome Atlas data, hsa-miR-508, hsa-miR-509-2, and hsa-miR-526b expression levels were significantly lower in early-stage CESC patients with LNM than in patients without LNM. A multivariate analysis suggested that three miRNAs were prognostic factors for CESC (P<0.05). The target genes were identified to be involved in the MAPK, cAMP, PI3K/Akt, mTOR, and estrogen cancer signaling pathways. Protein–protein interaction network analysis showed that TP53, MMP1, NOTCH1, SMAD4, and NFKB1 were the most significant hub proteins. Conclusion Our results indicate that hsa-miR-508, hsa-miR-509-2, and hsa-miR-526b may be potential diagnostic biomarkers for early-stage CESC with LNM, and serve as prognostic predictors for patients with CESC.
