Small noncoding RNAs, including endogenous antisense RNAs and microRNAs, are involved in many different cellular processes. This issue's Molecular Medicine Select highlights recent work investigating the roles of these RNAs in various aspects of tumorigenesis, suggesting new prognostic, and possibly therapeutic, tools for treating cancer. MicroRNAs (miRNAs) are small noncoding RNAs that negativ...

Circular RNAs (circRNAs) are a class of endogenous noncoding RNA, which were previously considered as byproduct RNA splicing error. Numerous studies have demonstrated the altered expression circRNAs in organ tissues during pathological conditions and their involvements disease pathogenesis progression, including cancers. In colorectal cancer (CRC), multiple been identified characterized “oncoge...

miRNAs have been recently implicated as drivers in several carcinogenic processes, where they can act either as oncogenes or as tumor suppressors. Schwannomas arise from Schwann cells, the myelinating cells of the peripheral nervous system. These benign tumors typically result from loss of the neurofibromatosis type 2 (NF2) tumor suppressor gene. We have recently carried out high-throughput miR...

mirnas are endogenous small noncoding rnas that can regulate many cellular processes. different expression levels of several mirnas have been detected in glioblastomas. function of mirnas and targets have been well studied in recent years. according to these studies, the role of mirnas in glioblastoma pathogenesis have been defined. mirnas have affected many processes in gbm such as apoptosis, ...

Abstract Wild-type KRAS ( WT ) amplification has been shown to be a secondary means of activation in cancer and associated with poor survival. Nevertheless, the precise role overexpression lung progression is largely unexplored. Here, we identify characterize KRAS-responsive lncRNA, KIMAT1 (ENSG00000228709) show that it correlates levels both cell lines specimens. Mechanistically, MYC target dr...

Micro RNAs (miRNAs) represent a class of short, non-coding, endogenous RNAs which play important roles in post-transcriptional regulation of gene expression. While the diverse functions of miRNAs in model plants have been well studied, the impact of miRNAs in crop plant biology is poorly understood. Here we used high-throughput sequencing and bioinformatics analysis to analyze miRNAs in the tub...

A discontinuous pattern of LOH at chromosome 3p has been reported in 87% of primary breast cancers. Despite the identification of several tumor suppressor genes in this region, there has yet to be a detailed analysis of noncoding RNAs including miRNAs in this region. In this study, we identified 16 aberrant miRNAs in this region and determined several that are frequently lost or amplified in br...

Osteosarcoma is the most common bone cancer in children and young adults. Surgery and multi-agent chemotherapy are the standard treatment regimens for this disease. New therapies are being investigated to improve overall survival in patients. Molecular targets that actively modulate cell processes, such as cell-cycle control, cell proliferation, metabolism, and apoptosis, have been studied, but...

The Epstein-Barr virus (EBV) is an oncogenic human Herpes virus found in ∼15% of diffuse large B-cell lymphoma (DLBCL). EBV encodes miRNAs and induces changes in the cellular miRNA profile of infected cells. MiRNAs are small, non-coding RNAs of ∼19-26 nt which suppress protein synthesis by inducing translational arrest or mRNA degradation. Here, we report a comprehensive miRNA-profiling study a...

BACKGROUND Lung cancer is one of the most common types of cancer worldwide and is characterized by a poor prognosis, related to both late diagnosis and lack of effective treatments. In the last years, microRNAs (miRNAs) have been demonstrated to have an important role in tumor microenvironment and immune regulation. These RNAs can be categorized into tumor-suppressor genes, such as let-7 family...
