Abstract
Cirrhosis is a severe form of liver fibrosis that results in the irreversible replacement of liver tissue with scar tissue in the liver. Environmental toxicity, infections, metabolic causes, or other genetic factors including autoimmune hepatitis can lead to chronic liver injury and can result in inflammation and fibrosis. This activates myofibroblasts to secrete ECM proteins, resulting in the formation of fibrous scars on the liver. Fibrosis regression is possible through the removal of pathophysiological causes as well as the elimination of activated myofibroblasts, resulting in the reabsorption of the scar tissue. To date, a wide range of antifibrotic therapies has been tried and tested, with varying degrees of success. These therapies include the use of growth factors, cytokines, miRNAs, monoclonal antibodies, stem-cell-based approaches, and other approaches that target the ECM. The positive results of preclinical and clinical studies raise the prospect of a viable alternative to liver transplantation in the near future. The present review provides a synopsis of recent antifibrotic treatment modalities for the treatment of liver cirrhosis, as well as a brief summary of clinical trials that have been conducted to date.

Abstract
Renal cell carcinoma (RCC) is the second most common cancer of the urinary system, accounting for approximately 10–15% of kidney cancers in the world. Clear cell renal cell carcinoma (ccRCC) is the most common RCC subtype with the highest mortality. Surgical resection or puncture of tumor tissue is still an important clinical treatment and diagnosis of ccRCC, but its high recurrence rate and poor prognosis often lead to the short survival period of patients. Hence, the development of novel molecular biomarkers is of great clinical importance. miRNAs are endogenous non-coding small RNAs with a length of 19–24 nt. A growing number of studies have reported that miRNAs, as proto-oncogenes or tumor suppressor genes, play a key role in the development of ccRCC and might be effective diagnostic and prognostic biomarkers. In addition, miRNAs can also predict the efficacy of treatment drug, thus improving the accuracy of clinical medication. Furthermore, non-invasive detection of miRNAs or extracellular vesicles (EV) in body fluids has better convenience and repeatability, which shows remarkable advantages compared with tissue detection. In this review, we summarized the typical miRNAs reported in recent years and place emphasis on evaluating miRNAs in different body fluids to provide reference for the clinical diagnosis and prognosis of ccRCC in the future.

Abstract
BACKGROUND MicroRNAs (miRNAs), a group of non-coding post-transcriptional regulators of gene expression, are dysregulated in clear cell renal cell carcinoma (ccRCC) and play an important role in carcinogenesis. Our prior work identified a subset of miRNAs in pT1 ccRCC tumors associated with progression to metastatic disease. OBJECTIVE To investigate the impact of two of these dysregulated miRNA, miR-15a-5p and -26a-5p, in an effort to elucidate the mechanisms underpinning aggressive forms of stage I ccRCC. METHODS The ccRCC cell line 786-O was transfected with pre-miRs-15a-5p and -26a-5p to rescue expression. Cell proliferation was measured via MT Cell Viability Assay. O-GlcNAc-transferase (OGT), a known protein in ccRCC proliferation, was identified by bioinformatics analysis as a target of both miRNA and validated via luciferase reporter assay to confirm binding of each miR to the 3' untranslated region (UTR). OGT protein expression was evaluated via western blotting. RESULTS Luciferase assay confirmed specificity of miR-15a-5p and -26a-5p for the OGT UTR. Western blot analysis for OGT showed reduced expression following co-transfection of both miRNAs compared to negative control or individual transfection. Co-transfection of these miRNAs greatly reduced proliferation when compared to negative control or the individual transfections. CONCLUSION Our results indicate that the dysregulation of miR-15a-5p and -26a-5p contribute cooperatively to the proliferation of ccRCC through their regulation of OGT. These results give insight into the pathogenesis of aggressive early stage ccRCC and suggest potential therapeutic targets for future research.

Abstract
Endothelial cell proliferation disorder caused by vascular injury seems to be one of the causes of atherosclerosis, which is the pathological basis of coronary heart disease. The role of STAT3 in the regulation of microRNAs and endothelial dysfunction in atherosclerosis is unclear. STAT3 can be activated by cytokine IL-6 and up regulate the expression of CX3CL1. In addition, microRNA-15a-5p (miR-15a-5p) inhibited the transcription of CX3CL1, the proliferation of vascular endothelial cells and the proliferation of STAT3 regulated vascular endothelial cells. STAT3 positively regulates the expression of CX3CL1, and then down-regulates the inhibition of CX3CL1 by over-expression of miR-15a-5p, thus forming an elimination feedback loop to control the proliferation of HUVECs and affect the progression of atherosclerosis. In conclusion, miR-15a-5p may be the therapeutic target of the pathological basis of coronary atherosclerosis.

Abstract
Objective: MicroRNAs are short, noncoding RNA molecules that negatively regulate the stability and translational efficiency of target mRNAs. They are critical regulators of growth and development. Our aim was to identify microRNAs involved in the growth and regulation of infantile hemangiomas. In addition, we searched for the presence of Piwi-interacting RNAs in hemangioma tissue as another regulator of infantile hemangiomas. Methods: RNA was extracted from hemangioma specimens from 3 clinical, age-based categories: proliferative (N = 16), quiescent (N = 8), and involuting (N = 9). RNAs from human dermal microvascular endothelial cells were used as controls. MicroRNA microarray was performed, and the expression profiles of the hemangiomas and endothelial cells were compared using the t test. 5' End-labeling of RNA of our hemangioma specimens was performed for Piwi-interacting RNA detection. Results: Analysis confirmed statistically significant downregulated (N = 18) and upregulated (N = 15) microRNAs. Piwi-interacting RNA analysis did not detect Piwi-interacting RNA transcripts in the hemangioma specimens. Conclusions: The differential expression of microRNAs found in our hemangioma specimens provides insight into the regulation of hemangioma formation and proliferation, quiescence, and fibrofatty involution. Piwi-interacting RNA transcripts were not detected in the hemangioma specimens. These novel findings will help in establishing new therapeutic and diagnostic initiatives for these tumors.

Abstract
As a kinase at the crossroads of numerous metabolic and cell growth signaling pathways, glycogen synthase kinase-3 beta (GSK-3β) is a highly desirable therapeutic target in cancer. Despite its involvement in pathways associated with the pathogenesis of several malignancies, no selective GSK-3β inhibitor has been approved for the treatment of cancer. The regulatory role of GSK-3β in apoptosis, cell cycle, DNA repair, tumor growth, invasion, and metastasis reflects the therapeutic relevance of this target and provides the rationale for drug combinations. Emerging data on GSK-3β as a mediator of anticancer immune response also highlight the potential clinical applications of novel selective GSK-3β inhibitors that are entering clinical studies. This manuscript reviews the preclinical and early clinical results with GSK-3β inhibitors and delineates the developmental therapeutics landscape for this potentially important target in cancer therapy.

Abstract
In previous investigations, we reported that peroxisome proliferator-activated receptor β/δ (PPARβ/δ) activation by GW501516 inhibits proliferation and promotes apoptosis in the undifferentiated C666-1 nasopharyngeal carcinoma (NPC) cells by modulating caspase-dependent apoptotic pathway. In the present study, the mechanism by which GW501516 induces apoptosis was explored from the perspective of microRNA (miRNA) expression. Among the assayed miRNAs that were involved in regulating the expression of antiapoptotic protein Bcl-2, miR-206 was increased significantly and specifically by GW501516 in C666-1 cells at both the in vitro level and at the in vivo xenograft samples. The induction on miR-206 expression caused by GW501516 was capable of being antagonized by the PPARβ/δ antagonist GSK3787 and AMPK antagonist dorsomorphin in C666-1 cells. GW501516's suppression on the growth and apoptosis of C666-1 cells was found to be dependent on the presence of miR-206. miR-206 overexpression resulted in suppressed proliferation and colony formation ability, and further triggered increased apoptosis in C666-1 cells in a caspase-dependent manner. The expression of cleaved caspase 3 and caspase 9, and the ratio of Bax to Bcl-2 were elevated remarkably by miR-206. Consistent with the in vitro result, miR-206 was corroborated to suppress the ectopic NPC xenograft tumorigenesis that derived from the C666-1 cells in BALB/c nu/nu mice. Taken together, the current data demonstrated that miR-206 plays a critical role in the direct apoptosis-promoting effect induced by GW501516 in C666-1 cells. Furthermore, the emphasized tumor-suppressive role of miR-206 in the C666-1 cells indicates that it has the potential to provide a new therapeutic approach for the undifferentiated NPC.

Abstract
Human papillomaviruses (HPVs) have important roles in the development and progression of cervical cancer, but the underlying mechanisms are yet to be fully elucidated. MicroRNA-130a (miR-130a) has previously been reported to promote cervical cancer growth. However, the underlying molecular mechanisms by which miR-130a promotes cervical cancer progression have remained largely elusive. In the present study, polymerase chain reaction and western blot analyses were performed to examine the expression levels of miR-130a and associated proteins. A wound healing assay and a Transwell assay were applied to study cell migration and invasion. A luciferase reporter gene assay was performed to confirm the targeting associations of miR-130a. It was observed that miR-130a was significantly upregulated in cervical cancer tissues compared with that in adjacent non-tumorous tissues. High expression of miR-130a was significantly associated with lymph node metastasis and an advanced clinical stage of cervical cancer. Furthermore, the expression of miR-130a was also higher in HPV(+) cervical cancer cell lines compared with that in HPV(-) cells. Knockdown of HPV18 E6 significantly inhibited the expression of miR-130a in HeLa cervical cancer cells. Furthermore, knockdown of miR-130a reduced the migration and invasion of HeLa cells. Tissue inhibitor of metalloproteinase 2 (TIMP2), an antagonist of matrix metalloproteinase 2 (MMP2), was identified as a novel, direct target gene of miR-130a. The expression of TIMP2 was negatively mediated by miR-130a, and HPV18 E6 inhibited the expression of TIMP2 in HeLa cells. Furthermore, knockdown of TIMP2 rescued the suppressive effects of miR-130a downregulation on the migration and invasion of HeLa cells. In summary, the present study suggests that HPV18 E6 promotes the expression of miR-130a, which further inhibits the expression of TIMP2 and promotes cervical cancer cell invasion. Therefore, HPV/miR-130a/TIMP2 signaling may be a potential target for the prevention of cervical cancer metastasis.

Abstract
The long non-coding RNA X inactive-specific transcript (XIST) has been implicated in certain human cancers, including osteosarcoma (OS), but the molecular mechanism of XIST underlying OS progression remains to be fully uncovered. In the present study, reverse transcription-quantitative polymerase chain reaction data demonstrated that XIST was significantly upregulated in OS tissues and cell lines (Saos-2, U2OS, HOS and MG63) compared with adjacent non-tumour tissues and normal human osteoblast cell line HFOB1.19. Bioinformatics analysis and luciferase reporter gene assay data demonstrated that XIST could directly target microRNA (miR)-137 and negatively regulate the expression of miR-137 in Saos-2 and U2OS cells. Furthermore, miR-137 was markedly downregulated in OS tissues and cell lines. An inverse association between XIST and miR-137 expression was observed in OS tissues. Knockdown of XIST caused a significant reduction in cell proliferation and invasion and suppressed matrix metalloproteinase (MMP2) and MMP9 protein levels in Saos-2 and U2OS cells. Furthermore, inhibition of miR-137 expression abolished the effects of XIST downregulation on the proliferation and invasion of OS cells. In summary, the present study suggests that XIST promotes OS cell proliferation and invasion by inhibition of miR-137 expression. Thus, XIST may be a potential therapeutic target for the treatment of OS.

Abstract
MicroRNAs (miRNAs) are the non-coding class of minute RNA molecules that negatively control post-transcriptional regulation of various functional genes. These miRNAs are transcribed from the loci present in the introns of functional or protein-coding genes, exons of non-coding genes, or even in the 3'-untranslated region (3'-UTR). They have potential to modulate the stability or translational efficiency of a variety of target RNA [messenger RNA (mRNA)]. The regulatory function of miRNAs has been elucidated in several pathological conditions, including neurological (Alzheimer's disease and Parkinson's disease) and cardiovascular conditions, along with cancer. Importantly, miRNA identification in cancer progression and invasion has evolved as an incipient era in cancer treatment. Several studies have shown the influence of miRNAs on various cancer processes, including apoptosis, invasion, metastasis and angiogenesis. In particular, apoptosis induction in tumor cells through miRNA has been extensively studied. The biphasic mode (up- and down-regulation) of miRNA expression in apoptosis and other cancer processes has already been determined. The findings of these studies could be utilized to develop potential therapeutic strategies for the management of various cancers. The present review critically describes the oncogenic and tumor suppressor role of miRNAs in apoptosis and other cancer processes, therapy resistance, and use of their presence in the body fluids as biomarkers.

Taurine upregulated gene 1 (TUG1), a long non-coding RNA (lncRNA), has recently been suggested to be associated with the development of osteosarcoma (OS), but the underlying molecular mechanism still remains largely unclear. In the present study, it was revealed that TUG1 was significantly upregulated whereas miR-212-3p was significantly downregulated in OS tissues and cell lines, when compared with adjacent non-tumor tissues and normal osteoblasts cell lines, respectively. An inverse association between the TUG1 and miR-212-3p expression was also observed in OS tissues. Furthermore, TUG1 directly interacted with miR-212-3p and negatively regulated the expression of miR-212-3p in OS cells. In vitro experiments further indicated that inhibition of TUG1 suppressed the proliferation and invasion of OS cells. Furthermore, knockdown of miR-212-3p eliminated the suppressive effects of TUG1 inhibition on the proliferation and invasion of OS cells. Taken together, these findings demonstrate that TUG1 promotes OS cell proliferation and invasion by inhibition of miR-212-3p expression, thus suggesting that TUG1 may become a potential therapeutic target for OS.

Long noncoding RNA HULC accelerates liver cancer by inhibiting PTEN via autophagy cooperation to miR15a. Mol Cancer 2018; 17:94. [PMID: 29895332 PMCID: PMC5998602 DOI: 10.1186/s12943-018-0843-8] [Citation(s) in RCA: 154] [Impact Index Per Article: 25.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2018] [Accepted: 06/01/2018] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Long noncoding RNA HULC is highly up-regulation in human hepatocellular carcinoma (HCC). However, the functions of HULC in hepatocarcinogenesis remains unclear. METHODS RT-PCR, Western blotting, Chromatin immunoprecipitation (CHIP) assay, RNA Immunoprecipitation (RIP) and tumorignesis test in vitro and in vivo were performed. RESULTS HULC is negatively associated with expression of PTEN or miR15a in patients of human liver cancer. Moreover, HULC accelerates malignant progression of liver cancer cells in vitro and in vivo. Mechanistically, HULC increasesthe expression of P62 via decreasing mature miR15a. On the other hand, excessive HULC increases the expression of LC3 on the level of transcription and then activates LC3 through Sirt1 (a deacetylase). Notably, HULC enhanced the interplay between LC3 and ATG3. Furthermore, HULC also increases the expression of becline-1(autophagy related gene). Therefore, HULC increases the cellular autophagy by increasing LC3II dependent on Sirt1.Noteworthy, excessive HULC reduces the expression of PTEN, β-catenin and enhances the expression of SAPK/JUNK, PKM2, CDK2, NOTCH1, C-Jun in liver cancer cells. Of significance, our observations also revealed that HULC inhibited PTEN through ubiquitin-proteasome system mediated by autophagy-P62.Ultimately,HULC activates AKT-PI3K-mTOR pathway through inhibiting PTEN in human liver cancer cells. CONCLUSIONS This study elucidates a novel mechanism that lncRNA HULC produces a vital function during hepatocarcinogenesis.

Abstract
Various microRNAs (miRs) have been demonstrated to serve important roles in gastric cancer (GC). miR-153 in particular has been reported to serve a suppressive role in GC; however, the underlying mechanism remains unclear. In the present study Reverse transcription-quantitative polymerase chain reaction and western blot analysis were used to examine the mRNA and protein expression of Kruppel-like factor 5. An MTT, wound healing and transwell assay were used to study cell proliferation, migration and invasion, respectively. In the present study, quantitative polymerase chain reaction data indicated that miR-153 was significantly downregulated in GC tissues compared with the adjacent non-tumor tissues. In addition, the reduced expression of miR-153 was significantly associated with GC aggressiveness and poor prognosis of patients. The expression of miR-153 was also reduced in GC cell lines, including KATO III, NCI-N87, SNU-16 and SNU-5, when compared with normal gastric epithelial GES-1 cells. Overexpression of miR-153 in the GC SNU-5 cells by miR-153 mimic transfection significantly inhibited the cell proliferation, migration and invasion. Furthermore, KLF5 was identified as a target gene of miR-153 in SNU-5 cells by bioinformatics prediction. It was observed that KLF5 was significantly upregulated in GC tissues and cell lines, and its expression was negatively regulated by miR-153 in SNU-5 cells. Overexpression of KLF5 impaired the suppressive effects of miR-153 on the proliferation, migration and invasion of SNU-5 cells. In conclusion, the present study demonstrated that miR-153 serves a tumor suppressive role in GC, at least partly, through directly targeting KLF5, thus highlighting the clinical significance of miR-153 in GC.

Abstract
MicroRNAs (miRs), a class of small non-coding RNAs, have been demonstrated to perform promoting or suppressive roles in various types of human malignancy. Deregulation of miR-195 has been observed in numerous types of human cancer, including cervical cancer; however, the detailed molecular mechanism of miR-195 underlying the malignant progression of cervical cancer remains largely unclear. In the present study, miR-195 was significantly down-regulated in cervical cancer tissue samples compared with adjacent non-tumor tissue samples, and the reduced expression level of miR-195 was associated with node metastasis and an advanced clinical stage in cervical cancer. Furthermore, the patients with low miR-195 expression levels demonstrated shorter survival times when compared with those with high miR-195 expression levels. In vitro experiments indicated that miR-195 exerted suppressive effects on the proliferation, migration and invasion of cervical cancer cells. Luciferase reporter gene assay identified defective in cullin neddylation 1 domain containing 1 (DCUN1D1) as a novel target gene of miR-195 and the expression level of DCUN1D1 was identified to be negatively regulated by miR-195 in cervical cancer cells. DCUN1D1 was significantly upregulated in cervical cancer, with a negative correlation to miR-195 expression. Furthermore, upregulation of DCUN1D1 was associated with the malignant progression and poor prognosis of cervical cancer. DCUN1D1 overexpression attenuated the suppressive effects of miR-195 on the malignant phenotypes of cervical cancer cells. Notably, the expression levels of miR-195 were significantly lower in HeLa [human papilloma virus (HPV)18+] and SiHa (HPV16+) cells compared with those in C33A (HPV−) cells, and knockdown of E6 using small interfering RNA significantly increased the miR-195 expression while the DCUN1D1 expression level was reduced in HeLa and SiHa cells. Thus, these findings indicate that miR-195 exerts a suppressive role in cervical cancer by targeting DCUN1D1. Therefore, miR-195 may present as a potential therapeutic candidate for cervical cancer.

Abstract
Nasopharyngeal carcinoma (NPC), which arises from the nasopharynx epithelium, is most common in Southeast Asia, particularly in Southern China. To date, a variety of microRNAs have been demonstrated to serve key functions in the progression and development of NPC. microRNA-425 (miR-425) has previously been reported to be frequently abnormally expressed in a number of different types of human cancer, including lung, gastric, cervical, breast and prostate cancer. However, to the best of our knowledge, the expression patterns, functions and underlying mechanisms of miR-425 in NPC remain largely unexplored. In the present study, the expression of miR-425 was revealed to be low in NPC tissues and cell line. Resumption of miR-425 expression suppressed cell viability and invasion in NPC. Hepatoma-derived growth factor (HDGF) was identified as a direct target gene of miR-425 in NPC. HDGF was highly expressed at mRNA and protein levels in NPC tissues. Additionally, HDGF mRNA was negatively correlated with miR-425 expression in NPC tissues. Furthermore, overexpression of HDGF almost completely rescued the tumor-suppressing effects of miR-425 on NPC cell viability and invasion. Taken together, these results demonstrated that miR-425 acted as a tumor suppressor in NPC by targeting HDGF, suggesting that it may be a novel therapeutic target for the treatments of patients with NPC.

Abstract
Nasopharyngeal carcinoma (NPC) is a cancer pattern that often develops in the epithelial cells of the nasopharynx. miR-100 is a miRNA that has been identified in a number of cancers. The aim of the present study was to investigate whether miR-100 can affect cell migration and proliferation of NPC by targeting insulin-like growth factor 1 receptor (IGF1R). Western blot analysis was used to determine the protein levels of genes. The reverse transcription-quantitative PCR (RT-qPCR) was used to detect the expression level of miR-100 and IGF1R. Transwell assay was used to detect the migration and invasion of cell lines. The luciferase reporter assay was employed to confirm the target gene of miR-100. miR-100 expression was highly reduced in NPC tissues compared with non-cancerous tissues. Overexpression of miR-100 significantly inhibited the migration and invasion of NPC cell lines C666-1 and SUNE1. IGF1R was a downstream target of miR-100 and was downregulated by miR-100. Knockdown of IGF1R by siRNA suppressed cell proliferation of the C666-1 cell line. The newly identified miR-100/IGF1R axis offers novel biomarkers for the therapeutic intervention of NPC treatment. As a result, our findings suggest that miR-100 plays an important role in suppressing migration and invasion of NPC cells and suppresses IGF1R expression by directly targeting its 3'-UTR. It is suggested that miR-100 may be a novel therapeutic target of microRNA-mediated suppression of cell migration and invasion in NPC. However, the role of the miR-100/IGF1R axis in NPC progression needs further investigation.

Abstract
microRNAs (miRs) serve important roles in various human cancer types. Recently, miR-23a has been indicated as an oncogene in gastric cancer, but the underlying mechanism remains unclear. In the present study, reverse transcription-quantitative polymerase chain reaction and western blot analysis was used to explore the effects of miR-23a in gastric cancer. Additionally, cell proliferation, migration and invasion were examined using an MTT assay, wound healing assay and Transwell assay, respectively. Furthermore, a luciferase reporter gene assay was used to confirm the target association. It was determined that miR-23a was significantly upregulated in gastric cancer tissues and cell lines compared with adjacent tissues, and a normal gastric epithelial cell line. Furthermore, its upregulation was significantly associated with cancer progression and poor prognosis of patients. Knockdown of miR-23a caused a notable reduction in the proliferation, migration and invasion of gastric cancer AGS cells. Sprouty homolog 2 (SPRY2) was then predicted to be target gene of miR-23a. A luciferase reporter gene assay data demonstrated that miR-23a has the ability to directly bind to the 3′-untranslational region of SPRY2 mRNA. Further investigation demonstrated that SPRY2 was significantly downregulated in gastric cancer tissues and cell lines, and the protein expression of SPRY2 was negatively regulated by miR-23a in AGS cells. Furthermore, knockdown of SPRY2 reduced the suppressive effects of miR-23a inhibition in AGS cell proliferation, migration and invasion. In addition, the activity of extracellular signal-regulated kinase (ERK) signaling was also inhibited by the miR-23a/SPRY2 knockdown in AGS cells. The present study indicated that miR-23a serves a promoting role in gastric cancer via targeting SPRY2 and downstream ERK signaling.

Abstract
Hepatocellular carcinoma (HCC) is the most common primary liver cancer, ranking as the second leading cause of male cancer death worldwide. MicroRNA-29 (miR-29) has been demonstrated to act as a tumor suppressor in HCC. However, the regulatory mechanism of miR-29 underlying HCC growth and metastasis still remains obscure. In the present study, we showed that the expression of miR-29 was significantly reduced in HCC tissues and cell lines, and low miR-29 expression was associated with disease progression and shorter survival time of HCC patients. In vitro experiments showed that restoration of miR-29 expression caused a significant reduction in HCC cell proliferation, migration and invasion. Insulin like growth factor 2 mRNA binding protein 1 (IGF2BP1) was identified as a novel target gene of miR-29. The expression of IGF2BP1 was significantly increased in HCC tissues and cell lines. Moreover, IGF2BP1 was negatively regulated by miR-29 at the post-transcriptional levels in HCC cells. Furthermore, overexpression of IGF2BP1 attenuated the suppressive effects of miR-29 on the proliferation, migration, and invasion of HCC cells. According to these above findings, our study suggests that miR-29 may play a suppressive role in HCC growth and metastasis through directly targeting IGF2BP1. Therefore, miR-29 may be used as a potential candidate for the treatment of HCC.

Abstract
Cutaneous squamous cell carcinoma (CSCC) is the second most common type of skin cancer with increasing incidence. In recent years, several microRNAs (miRs) have been demonstrated to serve an oncogenic or tumor suppressive role in CSCC. However, the exact role of miR-34a in CSCC and the underlying regulatory mechanism remain unclear. The present study aimed to investigate the regulatory mechanism of miR-34a in the malignant phenotypes of CSCC cells using MTT assay, wound healing assay and transwell assay. It was observed that miR-34a was significantly downregulated in CSCC tissues and cell lines, and low miR-34a expression was associated with the aggressive progression of CSCC. Restoration of miR-34a significantly suppressed the proliferation, migration and invasion of CSCC SCL-1 cells. High-mobility group box 1 (HMGB1) was then identified as a target gene of miR-34a in SCL-1 cells using bioinformatics prediction. The expression of HMGB1 was significantly upregulated in the CSCC tissues and cell lines. Furthermore, the protein expression of HMGB1 was negatively regulated by miR-34a in SCL-1 cells, while overexpression of HMGB1 impaired the inhibitory effects of miR-34a on SCL-1 cells. These findings suggest that miR-34a represses the malignant phenotypes of CSCC cells, at least partly, via the inhibition of HMGB1. Therefore, miR-34a may be used as a promising therapeutic candidate for CSCC.

Abstract
The authors' previous study revealed that the serum levels of microRNA (miR)-663b are significantly increased in patients with nasopharyngeal carcinoma (NPC), and are associated with NPC progression and poor prognosis. However, the molecular mechanism of underlying NPC growth and metastasis remains unclear. In the present study, quantitative polymerase chain reaction and western blot analyses were performed to examine changes to mRNA and protein expression, respectively. MTT, wound healing and Transwell assays were used to examine cell proliferation, migration and invasion, respectively. Luciferase reporter gene assays were performed to identify target genes of miR-663b. It was demonstrated that miR-663b was significantly upregulated in NPC tissue compared with non-tumor nasopharyngeal epithelial tissue samples. Furthermore, miR-663b expression gradually increased with advancing stages of NPC, with the highest expression being observed in the latest stage IV. The increased expression of miR-663b was associated with advanced clinical stage and lymph node metastasis. In addition, miR-663b expression was increased in NPC cell lines compared with normal nasopharyngeal epithelial NP69 cells. Knockdown of miR-663b resulted in a significant reduction in the proliferation, migration and invasion of NPC CNE1 cells. Tumor suppressor candidate 2 (TUSC2) was identified as a novel target gene of miR-663b. It was further demonstrated that TUSC2 was significantly downregulated in NPC tissue samples and cell lines. miR-663b negatively regulated the expression of TUSC2 at the post-transcriptional level in CNE1 cells. Additionally, inhibition of TUSC2 expression attenuated the suppressive effects of miR-663b downregulation on the proliferation, migration and invasion of CNE1 cells. To the best of our knowledge, this is the first study to demonstrate that miR-663b, which is upregulated in NPC, promotes the proliferation, migration and invasion of NPC cells, partially through the inhibition of TUSC2 expression. Therefore, it is suggested that miR-663b is a promising therapeutic target for the treatment of patients with NPC.

[PMID: 28081468 DOI: 10.1016/j.biopha.2016.12.128] [Citation(s) in RCA: 34] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2016] [Revised: 12/28/2016] [Accepted: 12/31/2016] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND Accumulating evidence indicates that microRNAs are involved in various cellular processes, including cell proliferation, differentiation, apoptosis and metastasis. miR-15a is an important regulator of immune responses and angiogenesis, endogenous controls as well as potential targets and hallmarks of cancer. However, the role of miR-15a in intervertebral disc degeneration (IDD) has not been elucidated. METHODS Total RNA was extracted from degenerative nucleus pulposus (NP) tissues of 20 patients with IDD and NP cells, respectively. The expression levels of miR-15a were examined by quantitative real-time PCR. The stable overexpress or silence miR-15a expression cell lines and control cell lines were constructed by lentivirus infection. Subsequently, 3-(4,5-dimethylthia zol-2-yl)-2,5-diphenylte trazolium bromide (MTT) assay, flow cytometry test, TdT-mediated dUTP Nick-End Labeling (TUNEL) experiment, colony formation assay and western blot analysis were performed to detect the biological functions of miR-15a. Moreover, a luciferase reporter assay was conducted to confirm its target associations. RESULTS Herein, the results found that miR-15a was dramatically up-regulated in degenerative NP tissues and NP cells compared with the controls. Overexpression of miR-15a promoted NP cells proliferation and induced apoptosis. Moreover, apoptosis-related protein caspase-3 was significantly up-regulated and bcl-2 was observably down-regulated when NP cells were transfected with miR-15a mimics, while bax and caspase-3 were significantly down-regulated as well as bcl-2 was observably up-regulated when NP cells were transfected with miR-15a inhibitors. Further, luciferase reporter assay showed that MAP3K9, an upstream activator of MAPK kinase, was putative target of miR-15a. There was a negatively relationship between miR-15a and MAP3K9 expression in NP cells. In addition, knockdown MAP3K9 inhibited NP cells proliferation and promoted apoptosis, which further inhibited the activation of p38 and ERK MAPK pathway. CONCLUSION This present study revealed that miR-15a might be considered as a novel therapeutic target for IDD treatment.
