Abstract
Prostate cancer is a prevalent carcinoma among males, and conventional treatment options are often limited. Cytotoxic chemotherapy, despite its drawbacks, remains a mainstay. We propose a targeted co-delivery approach using nanoscale delivery units for Oncolytic measles virus (OMV) and vincristine (VC) to enhance treatment efficacy. The HA-coated OMV + VC-loaded TCs nanoformulation is designed for targeted oncolytic activity in prostate cancer. The CD44 expression analysis in prostate cancer cell lines indicates a significantly high expression in PC3 cells. The optimization of nanoformulations using Design of Expert (DOE) is performed, and the preparation and characterization of HA-coated OMV + VC-loaded TCs nanoformulations are detailed showing average particle size 397.2 ± 0.01 nm and polydispersity index 0.122 with zeta potential 19.7 + 0.01 mV. Results demonstrate successful encapsulation efficiency with 2.4 × 106 TCID50/Ml and sustained release of OMV and VC from the nanoformulation for up to 72 h. In vitro, assays reveal potent anticancer activity at 10 ± 0.71% cell viability in PC3 cells compared to 73 ± 0.66% in HPrEC and significant morphological changes at 90 µg/ml in dose and time-dependent manner. The co-formulation showed positive cell death 49.5 ± 0.02% at 50 µg PI/ml in PBS and 54.3% cell cycle arrest at the G2/M phase, 8.1% G0/G1 and 5.7% at S phase, with significant mitochondrial membrane potential (MMP) at 50 µg/ml, as assessed by flow cytometry (FACS). The surface-integrating ligand approach enhances the targeted delivery of the oncolytic virus and chemotherapeutic drug, presenting a potential alternative for prostate cancer treatment and suggested that co-administering VC and OMV in a nanoformulation could improve therapeutic outcomes while reducing chemotherapeutic drug doses.

Abstract
The predominant kind of liver cancer is hepatocellular carcinoma (HCC) that its treatment have been troublesome difficulties for physicians due to aggressive behavior of tumor cells in proliferation and metastasis. Moreover, stemness of HCC cells can result in tumor recurrence and angiogenesis occurs. Another problem is development of resistance to chemotherapy and radiotherapy in HCC cells. Genomic mutations participate in malignant behavior of HCC and nuclear factor-kappaB (NF-κB) has been one of the oncogenic factors in different human cancers that after nuclear translocation, it binds to promoter of genes in regulating their expression. Overexpression of NF-κB has been well-documented in increasing proliferation and invasion of tumor cells and notably, when its expression enhances, it induces chemoresistance and radio-resistance. Highlighting function of NF-κB in HCC can shed some light on the pathways regulating progression of tumor cells. The first aspect is proliferation acceleration and apoptosis inhibition in HCC cells mediated by enhancement in expression level of NF-κB. Moreover, NF-κB is able to enhance invasion of HCC cells via upregulation of MMPs and EMT, and it triggers angiogenesis as another step for increasing spread of tumor cells in tissues and organs. When NF-κB expression enhances, it stimulates chemoresistance and radio-resistance in HCC cells and by increasing stemness and population of cancer-stem cells, it can provide the way for recurrence of tumor. Overexpression of NF-κB mediates therapy resistance in HCC cells and it can be regulated by non-coding RNAs in HCC. Moreover, inhibition of NF-κB by anti-cancer and epigenetic drugs suppresses HCC tumorigenesis. More importantly, nanoparticles are considered for suppressing NF-κB axis in cancer and their prospectives and results can also be utilized for treatment of HCC. Nanomaterials are promising factors in treatment of HCC and by delivery of genes and drugs, they suppress HCC progression. Furthermore, nanomaterials provide phototherapy in HCC ablation.

Abstract
Hepatocellular carcinoma (HCC) is the main type of primary liver malignancy and the fourth leading cause of cancer-related death worldwide. MicroRNAs (miRNAs), a type of non-coding RNA that regulates gene expression mainly on post-transcriptional level has a confirmed and important role in numerous biological process. By regulating specific target genes, miRNA can act as oncogene or tumor suppressor. Recent evidence has indicated that the deregulation of miR-NAs is closely associated with the clinical pathological features of HCC. However, the precise regulatory mechanism of each miRNA and its targets in HCC has yet to be illuminated. This study demonstrates that both oncogenic and tumor suppressive miRNAs are crucial in the formation and development of HCC. miRNAs influence biological behavior including proliferation, invasion, metastasis and apoptosis by targeting critical genes. Here, we summarize current knowledge about the expression profile and function of miRNAs in HCC and discuss the potential for miRNA-based therapy for HCC.

Abstract
Hepatocellular carcinoma (HCC) is a highly lethal type of malignancies that possesses great loss of life safety to human beings worldwide. However, few effective means of curing HCC exist and its specific molecular basis is still far from being fully elucidated. Activation of nuclear factor kappa B (NF-κB), which is often observed in HCC, is considered to play a significant part in hepatocarcinogenesis and development. The emergence of regulatory non-coding RNAs (ncRNAs), particularly microRNAs (miRNAs) and long non-coding RNAs (lncRNAs), is a defining advance in cancer biology, and related research in this branch has yielded many diagnostic and therapeutic opportunities. Recent studies have suggested that regulatory ncRNAs act as inhibitors or activators in the initiation and progression of HCC by targeting components of NF-κB signaling or regulating NF-κB activity. In this review, we attach importance to the role and function of regulatory ncRNAs in NF-κB signaling of HCC and NF-κB-associated chemoresistance in HCC, then propose future research directions and challenges of regulatory ncRNAs mediated-regulation of NF-κB pathway in HCC.

Abstract
Background Cervical cancer is a lethal gynecologic cancer in women. Long non-coding RNA colorectal neoplasia differentially expressed (LncRNA CRNDE) was recognized as a significant oncogene in multiple cancers. However, the functional role of CRNDE in cervical cancer remains poorly explored. Methods The expression of CRNDE, microRNA-4262 (miR-4262) and zinc-finger E-box binding homeobox 1 (ZEB1) in cervical cancer tumors and cells was detected by quantitative real-time polymerase chain reaction (qRT-PCR). Colony formation and 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) were performed to detect cell viability. Flow cytometry and caspase-3 activity assay were conducted to evaluate cell apoptosis. The interaction between miR-4262 and CRNDE or ZEB1 was verified by dual-luciferase reporter system. Transwell assay was employed to evaluate cell migration and invasion. The relative protein expression was assessed by Western blot. Results CRNDE and ZEB1 were up-regulated, while miR-4262 was down-regulated in cervical cancer tissues and cells. We found that CRNDE sponged miR-4262 and ZEB1 was a target of miR-4262. In addition, miR-4262 inhibitor abolished CRNDE silencing-induced repression on cell proliferation, EMT, migration, invasion and promotion on cell apoptosis. Furthermore, ZEB1 rescued the effects of miR-4262 overexpression or CRNDE deletion on cervical cancer progression. Our data showed that CRNDE targeted miR-4262 to regulate ZEB1 expression in cervical cancer cells. Besides, CRNDE expedited cervical cancer progression through wnt/β-catenin pathway via sponging miR-4262 and altering ZEB1 expression. Conclusion Our findings demonstrated that CRNDE facilitated the progression of cervical cancer through activation of wnt/β-catenin pathway by regulating miR-4262/ZEB1 axis, representing a prospective targeted therapy for cervical cancer.

Abstract
AIM This study aimed to explore the role of lncRNA leukemia inhibitory factor receptor antisense RNA 1 (LIFR-AS1) on glioma and its underlying molecular mechanism. METHODS The expression of LIFR-AS1 and miR-4262 was detected by quantitative real-time polymerase chain reaction (qRT-RCR) in both glioma tissues and cell lines. Colony formation assay, 5-ethynyl-20-deoxyuridine (EdU) assay, flow cytometry and transwell assay were respectively conducted to detect cell clones, proliferation, apoptosis, migration and invasion. The effect of LIFR-AS1 on the chemoresistance to temozolomide (TMZ) of glioma cells was also analyzed. In addition, dual-luciferase reporter gene assay was performed to evaluate the luciferase activity. The expressions of nuclear factor-κB (NF-κB) p65, p-NF-κB p65 and inhibitor of κBα (IκBα) in glioma cells were measured by western blot. RESULTS LIFR-AS1 was lowly expressed and miR-4262 was highly expressed in glioma tissues and cell lines. LIFR-AS1 overexpression inhibited the proliferation, migration and invasion and promoted apoptosis of glioma cells. LIFR-AS1 overexpression also reduced the chemoresistance to TMZ of glioma cells. Moreover, LIFR-AS1 overexpression suppressed the activation of NF-κB signaling pathway in glioma cells. miR-4262 was the target gene of LIFR-AS1. We also found that miR-4262 abrogated the functions of LIFR-AS1 on cell proliferation, apoptosis, migration and invasion of glioma cells in the NF-κB pathway. CONCLUSION LIFR-AS1 could suppress the proliferation, migration and invasion and promote the apoptosis through modulating miR-4262/NF-κB pathway in glioma.

Abstract
Abdominal tumors (AT) in children account for approximately 17% of all pediatric solid tumor cases, and frequently exhibit embryonal histological features that differentiate them from adult cancers. Current molecular approaches have greatly improved the understanding of the distinctive pathology of each tumor type and enabled the characterization of novel tumor biomarkers. As seen in abdominal adult tumors, microRNAs (miRNAs) have been increasingly implicated in either the initiation or progression of childhood cancer. Moreover, besides predicting patient prognosis, they represent valuable diagnostic tools that may also assist the surveillance of tumor behavior and treatment response, as well as the identification of the primary metastatic sites. Thus, the present study was undertaken to compile up-to-date information regarding the role of dysregulated miRNAs in the most common histological variants of AT, including neuroblastoma, nephroblastoma, hepatoblastoma, hepatocarcinoma, and adrenal tumors. Additionally, the clinical implications of dysregulated miRNAs as potential diagnostic tools or indicators of prognosis were evaluated.

Abstract
BACKGROUND miRNA was recently detected as tumor suppressor or inducer in various cancers including gliomas. Due to the abnormal expression of miR-4262 in glioma cancer, we supposed that miR-4262 made efforts in proliferation and migration in glioma cancer. METHODS CCK-8, Transwell migration Assay and Wound-healing assay were appraisal assays for cell proliferation and migration. qRT-PCR and western blot were performed to test the expression of miR-4262, MMP2, MMP13 and LATS1 in glioma cancers tissues and cancer cells. The targeting detection between miR-4262 and LATS1 was detected by luciferase reporter assay. RESULTS miR-4262 expression was dramatically higher in glioma tumor tissues than in para-tumor control. Inhibition of miR-4262 in glioma cancer cells prominently inhibited cell proliferation and migration. Mechanically, downregulation of miR-4262 inhibited expression of matrix metalloproteinase (MMP) -2, -13. In addition, miR-4262 directly and negatively modulated expression of large tumor suppressor 1 (LATS1). Moreover, we discovered that overexpression of LATS1 could reverse the effects of miR-4262 on cell proliferation and migration, as well as the production of MMP-2, -13. CONCLUSIONS In glioma cancer, miR-4262 regulated cell proliferation and migration mediated by LATS1. This indicated that miR-4262 is a tumor inducer in glioma cancer and may be a feasible target for glioma therapy.

Abstract
Non-small cell lung cancer (NSCLC) is considered to be the primary cause of cancer-related mortalities worldwide. Paclitaxel (PTX), either as a monotherapy or in combination with other drugs, is an alternative therapy for advanced NSCLC. However, cancer cell resistance against PTX represents a major clinical problem. This study aimed to investigate the role and underlying mechanism of miR-4262 in PTX-resistant NSCLC. The levels of miR-4262 were analysed by quantitative reverse transcription polymerase chain reaction. A luciferase reporter assay and bioinformatics were used to explore the potential target gene of miR-4262. Regulation of miR-4262 and PTEN expressions in NSCLC was conducted by transfection. PTX-resistant A549 and H1299 cells were established by stepwise screening through increasing the PTX concentration in the cultures. In vivo, tumorigenesis experiments were used to explore the effects of miR-4262 and PTX. Cell proliferation, apoptosis and cell migration were detected using a CCK-8 assay, flow cytometry and Transwell migration assay, respectively. PI3 K/Akt pathway-related proteins were detected by western blot. miR-4262 expression was significantly upregulated in NSCLC tissues and cell lines, and miR-4262 targeted PTEN. In addition, miR-4262 induced PTX chemoresistance by promoting survival and migration in A549/PTX and H1299/PTX cells. Moreover, miR-4262 expression and PI3 K/Akt signalling pathway-related proteins were upregulated and PTEN was downregulated in A549/PTX and H1299/PTX. Our results indicate that miR-4262 enhances PTX resistance in NSCLC cells through targeting PTEN and activating the PI3 K/Akt signalling pathway. The inhibition of miR-4262 expression might be an improved treatment to overcome PTX resistance in NSCLC.

Abstract
BACKGROUND miR-4262 was identified as a tumor promoter in several cancers, but its exact role in gastric carcinoma is still largely unknown. METHODS The expression of miR-4262 was detected in gastric cancer tissues. Different concentrations of miR-4262 mimic and miR-4262 antagomir were respectively transfected into primary gastric carcinoma cells. After incubation for 72 h, the overexpression efficiencies were confirmed by qPCR, cell proliferation was detected with the CCK-8 assay, cell apoptosis was detected by using the PI/Annexin V Cell Apoptosis Kit, and cell invasion was detected with the Transwell invasion assay. The molecular mechanisms underlying the action of miR-4262 in gastric carcinoma cells were also explored. RESULTS In this study, we found that miR-4262 was significantly downregulated in gastric tissue from gastric cancer patients compared with that from the control group. Moreover, the level of miR-4262 was significantly lower in advanced gastric carcinoma. Additionally, lower level of miR-4262 was correlated with poorer prognosis and lower survival rate in gastric cancer patients. Then, different concentrations of miR-4262 mimic and miR-4262 antagomir were transfected into primary gastric carcinoma cells, respectively. The results showed that miR-4262 mimic suppressed proliferation and invasion and promoted cell apoptosis in a dose-dependent manner in gastric carcinoma cells. In contrast, miR-4262 antagomir increased proliferation and invasion and decreased cell apoptosis in a dose-dependent manner in gastric carcinoma cells. Furthermore, miR-4262 could directly target and suppress the expression of the proto-oncogene CD163. CONCLUSION Our findings indicate that lower level of miR-4262 predicts poorer prognosis in gastric patients, and miR-4262 can target proto-oncogene CD163 to suppress gastric cancer cell proliferation and invasion.

Abstract
Hepatocellular carcinoma (HCC) is known as one of the major health problems worldwide. Pathological analysis indicated that a variety of risk factors including genetical (i.e., alteration of tumor suppressors and oncogenes) and environmental factors (i.e., viruses) are involved in beginning and development of HCC. The understanding of these risk factors could guide scientists and clinicians to design effective therapeutic options in HCC treatment. Various viruses such as hepatitis B virus (HBV) and hepatitis C virus (HCV) via targeting several cellular and molecular pathways involved in HCC pathogenesis. Among various cellular and molecular targets, microRNAs (miRNAs) have appeared as key players in HCC progression. miRNAs are short noncoding RNAs which could play important roles as oncogenes or tumor suppressors in several malignancies such as HCC. Deregulation of many miRNAs (i.e., miR-222, miR-25, miR-92a, miR-1, let-7f, and miR-21) could be associated with different stages of HCC. Besides miRNAs, exosomes are other particles which are involved in HCC pathogenesis via targeting different cargos, such as DNAs, RNAs, miRNAs, and proteins. In this review, we summarize the current knowledge of the role of miRNAs and exosomes as important players in HCC pathogenesis. Moreover, we highlighted HCV- and HBV-related miRNAs which led to HCC progression.

Abstract
In this study, a homogeneous polysaccharide (GTP), with a molecular weight of 7.0 × 104 Da, was isolated from Green tea, which was only composed of glucose. The antitumor effects of GTP on prostate cancer (PC) cell line along with the possible mechanism was examined. First, we investigate the potential role of microRNA-93 (miR-93) in PC progression. Our results showed that miR-93 was significantly upregulated in human PC tissues and several PC cell lines, and its overexpression was correlated with poor survival in PC patients. Furthermore, functional analysis showed that miR-93 overexpression promoted the migration, invasion and proliferation of PC-3 cells transfected with miR-93 mimics, while its knockdown displayed an opposite result in DU145 cells following miR-93 inhibitor transfection. Additionally, in vivo tumorigenic studies on nude mice confirmed that miR-93 mimic treatment accelerated the growth of PC-3 xenograft tumors. As expected, GTP (25, 50 and 100 μg/ml) inhibited growth of PC-3 cells via inducing apoptosis, which was achieved by elevation of bax/bcl-2 ratio and caspae-3 protein expression, as well as a decrease of miR-93. Thus, miR-93 may be a potential therapeutic target by GTP for PC therapy.

Abstract
The present study aimed to investigate the effect and underlying mechanism of microRNA (miR)-4262 in the development of osteoarthritis (OA) in rats. Primary chondrocytes were separated from Sprague-Dawley rats and then treated with tumor necrosis factor-α (TNF-α). The level of miR-4262 was detected in TNF-α-treated chondrocytes, and then the miR-4262 or its target gene sirtuin type 1 (SIRT1) level was overexpressed, or knocked down. Furthermore, cell viability, cell apoptosis, cell autophagy and matrix synthesis, as well as the expressions of proteins associated with the phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) signaling pathway were detected. miR-4262 was significantly overexpressed in TNF-α-treated chondrocytes compared with untreated cells (P<0.05). TNF-α treatment or miR-4262 overexpression significantly decreased cell viability, autophagy-related proteins levels and matrix synthesis-related proteins levels, as well as increased the apoptotic rate in chondrocytes (P<0.05). Overexpression of SIRT1 significantly increased cell viability, autophagy-related proteins levels and matrix synthesis-related proteins levels, as well as decreased the apoptotic rate in TNF-α-treated chondrocytes (P<0.05). In addition, the effects of miR-4262 on cell viability, cell apoptosis, cell autophagy and matrix synthesis were inhibited by SIRT1 (P<0.05). Furthermore, upregulated miR-4262 remarkably increased the expressions of phosphorylated (p)-PI3K, p-AKT and p-mTOR (P<0.05) in TNF-α treated chondrocytes. The present study revealed that the upregulation of miR-4262 may promote the occurrence and development of OA in rats by regulating cell viability, cell apoptosis, cell autophagy, and matrix synthesis. Furthermore, these roles of miR-4262 may be associated with PI3K/AKT/mTOR signaling pathway.

Abstract
Background MicroRNAs are often abnormally expressed in human non‐small cell lung cancer (NSCLC) and are thought to play a critical role in the emergence or maintenance of NSCLC by binding to its target messenger RNA. We assessed the effects of miR‐155 on cell proliferation and invasion to elucidate the role played by miR‐155/PDCD4 in NSCLC. Methods Quantitative reverse transcription‐PCR, Western blotting, and cell counting kit‐8, luciferase, and transwell invasion assays were conducted on a normal human bronchial epithelial cell line (BEAS‐2B) and three NSCLC cell lines (SPC‐A‐1, A549, and H2170). Results We confirmed that miR‐155 was upregulated, while PDCD4 messenger RNA and protein levels were downregulated in NSCLC cell lines. miR‐155 negatively regulated PDCD4 at both transcriptional and post‐transcriptional levels. Moreover, PDCD4 was forecast as an assumed target of miR‐155 using bioinformatic methods and we demonstrated that PDCD4 was a direct target of miR‐155 using luciferase reporter assays. Furthermore, PDCD4 overexpression could restrain NSCLC proliferation and invasion induced by miR‐155. Conclusion Our results collectively demonstrate that miR‐155 exerts an oncogenic role in NSCLC by directly targeting PDCD4.

Abstract
More and more studies have reported that dysregulation of microRNAs (miRNAs) leads to the proliferation and EMT of multiple cancers. Recently, several reports have demonstrated that dysregulation of miR-4262 occurs in numerous cancers. However, its role and precise mechanism in human cervical cancer (CC) have not been well clarified. Hence, this study aimed to explore the biological roles and precise mechanisms of miR-4262 in CC cell lines. The level of miR-4262 was found to be significantly decreased in CC tissues and cell lines. Moreover, decreased expression of miR-4262 was closely related to increased expression of Kaiso (ZBTB33), which belongs to the BTB/POZ family, in CC tissues and cell lines. The proliferation and EMT of CC cells were inhibited by a miR-4262 mimic. However, downregulation of miR-4262 enhanced the proliferation and EMT of CC cells. Next, bioinformatics analysis predicted that miR-4262 might directly target the Kaiso gene. Besides, luciferase reporter assay had confirmed this result. Moreover, introduction of Kaiso in CC cells partially blocked the effects of miR-4262 mimic. In conclusion, miR-4262 suppressed the proliferation and EMT of CC cells by directly downregulating Kaiso.

Abstract
Recent studies have shown that miRNAs play vital roles in tumorigenesis. However, their effects on the epithelial-mesenchymal transition (EMT) in hepatocellular carcinoma (HCC) need to be better understood. Our present study demonstrates that miR-221, which is overexpressed in HCC tissues, promotes EMT in HCC cell lines by targeting a new gene, AdipoR1. First, overexpression of miR-221 was identified in 40 pairs of human HCC tumor and matched normal tissues. Moreover, we found that elevated miR-221 was strongly associated with worse clinicopathologic features in HCC patients. Next, the loss of miR-221 inhibited, but its restoration enhanced, the EMT process in HCC cell lines. Furthermore, bioinformatics software predicted that AdipoR1 would be a direct target of miR-221. We then observed negative regulation of miR-221 on AdipoR1 protein expression, and direct binding between them was further verified using dual-luciferase assays. In addition, knockdown of AdipoR1 resulted in promotion of the EMT in HCC cells, and AdipoR1 overexpression reversed the miR-221-induced EMT. Lastly, we found that the JAK/STAT3 pathway may be involved in the AdipoR1-mediated EMT process. In conclusion, miR-221 acts as a promoter of the EMT process in HCC cells by targeting AdipoR1, and this study highlights the potential effects of miR-221 on the prognosis and treatment of HCC.

Abstract
miRNAs have been shown to be involved in breast cancer growth and progression. miR-4262 is a potential tumor promoter in human cancers. In this study, we first investigated the role of miR-4262 in the proliferation and invasion of human breast cancer cells. Our results showed that, compared with the adjacent tissues and MCF-10A normal breast epithelial cells, miR-4262 was markedly increased in the breast cancer tissues and five cell lines, including MDA-MB-231, MDA-MB-468, MDA-MB-435, SKBR3, and MCF-7. Then the miR-4262 mimic or oligo anta-miR-4262 was transfected into MDA-MB-231 and MCF-7 breast cancer cell lines. The results showed that the miR-4262 mimic greatly increased the miR-4262 level and the proliferation and invasion of MDA-MB-231 and MCF-7 cells. In contrast, the anta-miR-4262 had a completely opposite effect on miR-4262 expression, cell proliferation, and cell invasion in MDA-MB-231 and MCF-7 cells. Moreover, bioinformatics and luciferase reporter gene assays confirmed that miR-4262 targeted the mRNA 3′-UTR region of KLF6 and KLF15, two characterized tumor suppressor genes. miR-4262 suppressed protein levels of KLF6 and KLF15 in MDA-MB-231 cells, and the suppression could be rescued by the transfection of pcDNA-KLF6 and -KLF15. In conclusion, miR-4262 positively regulates proliferation and invasion of human breast cancer cells via suppression of KLF6 and KLF15.

Abstract
MicroRNAs are often aberrantly expressed in breast cancer and postulated to play a causal role in the onset and maintenance of breast cancer by binding to its target mRNA. Here, we evaluated the effects of miRNA-183-5p on cell proliferation and apoptosis which attempted to elucidate the potential role of miR-183-5p/PDCD4 axis in human breast cancer. We found that the miR-183-5p expression level was extremely promoted in breast cancer in comparison with the adjacent normal tissues. Overexpression of miR-183-5p significantly enhanced the cell proliferation and inhibited cell apoptosis in MCF-7 and MDA-MB-231 cells. Moreover, PDCD4 was predicted as a putative target of miR-183-5p by bioinformatic approaches, and miR-183-5p negatively regulated the expression of PDCD4. Furthermore, knockdown of PDCD4 suppressed expression of p21 and p27, which was consistent with the result of the attachment of miR-183-5p. These data collectively demonstrate that miR-183-5p exerts oncomiRs effects in breast cancer, and may have broad impacts on the field of using antimiRs as anti-cancer drugs for breast cancer.

Abstract
Liver cancer, primarily hepatocellular carcinoma (HCC), is a major cause of cancer-related death worldwide. HCC is a suitable model of inflammation-induced cancer because more than 90% of HCC cases are caused by liver damage and chronic inflammation. Several inflammatory response pathways, such as NF-κB and JAK/STAT3 signaling pathways, play roles in the crosstalk between inflammation and HCC. MicroRNAs (miRNAs) are evolutionarily conserved, short endogenous, non-coding single-stranded RNAs that are involved in various biological and pathological processes by regulating gene expression and protein translation. Evidence showed that miRNAs play a pivotal role in hepatitis virus infection and serve as promoters or inhibitors of inflammatory response. Aberrant miRNA was observed during liver inflammation and HCC. Many dysregulated miRNAs modulate the initiation and progression of inflammation-induced HCC. This review summarizes the role and functions of miRNAs in inflammation-associated HCC, as well as the designed therapeutics targeting miRNAs to treat liver inflammation and HCC.
