Emerging evidence has shown that microRNAs (miRNAs) play essential roles in regulating human cancers development and progression. However, the underlying mechanisms remain to be further explored. MiRNAs are a class of endogenous, non-coding, 18-24 nucleotide length single-strand RNAs that moderate gene expression primarily at post-transcriptional level. There is a growing body of literature that recognizes the importance of microRNA (miR)-129 during the development of cancers. Aberrant expression of miR-129 has been detected in various types of human cancers and the validated target genes are involved in cancer-related biological processes such as DNA methylation, cell proliferation, apoptosis, cell cycle, and metastasis. In this review, we summarized the roles of miR-129 family members and their target genes in tumorigenesis and clinical treatment of human cancers, highlighting the potential roles of miR-129 as biomarkers for cancer diagnosis and prognosis, and promising tools for cancer treatment.

Abstract miRNAs, a major class of small noncoding RNAs approximately 18–25 nucleotides in length, function by repressing the expression of target genes through binding to complementary sequences in the 3′-UTRs of target genes. Emerging evidence has highlighted their important roles in numerous diseases, including human cancers. Recently, miR-190 has been shown to be dysregulated in various types of human cancers that participates in cancer-related biological processes, including proliferation, apoptosis, metastasis, drug resistance, by regulating associated target genes, and to predict cancer diagnosis and prognosis. In this review, we summarized the roles of miR-190-5p in human diseases, especially in human cancers. Then we classified its target genes in tumorigenesis and progression, which might provide evidence for cancer diagnosis and prognosis, promising tools for cancer treatment, or leads for further investigation.

AbstractSmall non-coding RNAs (ncRNAs) are vital regulators of biological activities, and aberrant levels of small ncRNAs are commonly found in precancerous lesions and cancer. PIWI-interacting RNAs (piRNAs) are a novel type of small ncRNA initially discovered in germ cells that have a specific length (24–31 nucleotides), bind to PIWI proteins, and show 2′-O-methyl modification at the 3′-end. Numerous studies have revealed that piRNAs can play important roles in tumorigenesis via multiple biological regulatory mechanisms, including silencing transcriptional and posttranscriptional gene processes and accelerating multiprotein interactions. piRNAs are emerging players in the malignant transformation of normal cells and participate in the regulation of cancer hallmarks. Most of the specific cancer hallmarks regulated by piRNAs are involved in sustaining proliferative signaling, resistance to cell death or apoptosis, and activation of invasion and metastasis. Additionally, piRNAs have been used as biomarkers for cancer diagnosis and prognosis and have great potential for clinical utility. However, research on the underlying mechanisms of piRNAs in cancer is limited. Here, we systematically reviewed recent advances in the biogenesis and biological functions of piRNAs and relevant bioinformatics databases with the aim of providing insights into cancer diagnosis and clinical applications. We also focused on some cancer hallmarks rarely reported to be related to piRNAs, which can promote in-depth research of piRNAs in molecular biology and facilitate their clinical translation into cancer treatment.

Epilepsy represents one of the most common neurological disorders characterized by abnormal electrical activity in the central nervous system (CNS). Recurrent seizures are the cardinal clinical manifestation. Although it has been reported that the underlying pathological processes include inflammation, changes in synaptic strength, apoptosis, and ion channels dysfunction, currently the pathogenesis of epilepsy is not yet completely understood. Long non-coding RNAs (lncRNAs), a class of long transcripts without protein-coding capacity, have emerged as regulatory molecules that are involved in a wide variety of biological processes. A growing number of studies reported that lncRNAs participate in the regulation of pathological processes of epilepsy and they are dysregulated during epileptogenesis. Moreover, an aberrant expression of lncRNAs linked to epilepsy has been observed both in patients and in animal models. In this review, we summarize latest advances concerning the mechanisms of action and the involvement of the most dysregulated lncRNAs in epilepsy. However, the functional roles of lncRNAs in the disease pathogenesis are still to be explored and we are only at the beginning. Additional studies are needed for the complete understanding of the underlying mechanisms and they would result in the use of lncRNAs as diagnostic biomarkers and novel therapeutic targets.

Circular RNAs (circRNAs) are a class of novel non-coding RNAs (ncRNAs). Emerging evidence demonstrates that circRNAs play crucial roles in many biological processes by regulating linear RNA transcription, downstream gene expression and protein or peptide translation. Meanwhile, recent studies have suggested that circRNAs have the potential to be oncogenic or anti-oncogenic and play vital regulatory roles in the initiation and progression of tumors. Circular RNA Forkhead box O3 (circ-Foxo3, hsa_circ_0006404) is encoded by the human FOXO3 gene and is one of the most studied circular RNAs acting as a sponge for potential microRNAs (miRNAs) (Du et al., 2016). Previous studies have reported that circ-Foxo3 is involved in the development and tumorigenesis of a variety of cancers (bladder, gastric, acute lymphocytic leukemia, glioma, etc.). In this review, we summarize the current studies concerning circ-Foxo3 deregulation and the correlative mechanism in various human cancers. We also point out the potential clinical applications of this circRNA as a biomarker for cancer diagnosis and prognosis.

miR-873 is a microRNA located on chromosome 9p21.1. miR-873-5p and miR-873-3p are the two main members of the miR-873 family. Most studies focus on miR-873-5p, and there are a few studies on miR-873-3p. The expression level of miR-873-5p was down-regulated in 14 cancers and up-regulated in 4 cancers. miR-873-5p has many targeted genes, which have unique molecular functions such as catalytic activity, transcription regulation, and binding. miR-873-5p affects cancer development through the PIK3/AKT/mTOR, Wnt/β-Catenin, NF-κβ, and MEK/ERK signaling pathways. In addition, the target genes of miR-873-5p are closely related to the proliferation, apoptosis, migration, invasion, cell cycle, cell stemness, and glycolysis of cancer cells. The target genes of miR-873-5p are also related to the efficacy of several anti-cancer drugs. Currently, in cancer, the expression of miR-873-5p is regulated by a variety of epigenetic factors. This review summarizes the role and mechanism of miR-873-5p in human tumors shows the potential value of miR-873-5p as a molecular marker for cancer diagnosis and prognosis.

MicroRNAs (miRNAs) contribute to cellular homeostasis and differentiation in many ways, and therefore play an important role in many pathophysiological events. The knowledge of small non-coding RNAmolecules has developed our understanding towards basic processes of cancer biology and the molecular mechanisms underlying tumor initiation and progression. MiRNA research field has grown to be more and more attractive as evidence is emerging that miRNAs possibly play vital regulatory roles in all fundamental biological processes. Notably, as research continues to reveal the mechanisms underlying cancer therapy efficacy, it is apparent that miRNAs contribute to responses to drug therapy and are themselves modified by drug therapy. One important field for miRNA research is to identify functions of miRNAs and the associated signaling pathways in the initiation, progression, metastasis and drug-resistance of tumors in order to propose novel, efficient target based therapeutics that directly target pathologically essential miRNAs and their allied target genes. Currently, miRNA signatures have increasing importance and use in the diagnosis and prognosis of various types of cancers. In this review, we have highlighted the role of various miRNAs in various cancers and other disease so that future of miRNAresearch will provide more interesting outcomes in terms of therapy and cure.

Hepatocellular carcinoma (HCC) is one of the most common malignant tumors in clinical practice. The pathogenesis of HCC is still unclear. Currently, the clinical treatment of HCC is poorly targeted and the therapeutic effect is poor. MicroRNAs (miRNAs) are closely related to the occurrence of HCC, and they are mainly involved in the occurrence and development of HCC through binding to target genes or acting on related signaling pathways. In recent years, studies have shown that miRNA can be used as a potential biomarker for diagnosis and prognosis of HCC. In addition, studies have also shown that miRNA plays a tumor-suppressing or tumor-promoting role in the process of HCC by regulating the biological processes of tumor cell proliferation, migration, invasion and metastasis. In this paper, the recent studies on miRNA signaling pathways related to the occurrence and development of HCC were reviewed, with a view to providing ideas for the clinical diagnosis and treatment of HCC.

Functional Mechanism

N6-methyladenosine (m6A) is the most prevalent internal modification of eukaryotic messenger RNAs (mRNAs). The m6A modification in RNA can be catalyzed by methyltransferases, or removed by demethylases, which are termed m6A writers and erasers, respectively. Selective recognition and binding by distinct m6A reader proteins lead mRNA to divergent destinies. m6A has been reported to influence almost every stage of mRNA metabolism and to regulate multiple biological processes. Accumulating evidence strongly supports the correlation between aberrant cellular m6A level and cancer. We summarize here that deregulation of m6A modification, resulting from aberrant expression or function of m6A writers, erasers, readers or some other protein factors, is associated with carcinogenesis and cancer progression. Understanding the regulation and functional mechanism of mRNA m6A modification in cancer development may help in developing novel and efficient strategies for the diagnosis, prognosis and treatment of human cancers.
