Novel molecular-targeted treatments show great prospects for radioiodine-refractory and surgically inoperable thyroid carcinomas. While aberrations in protein-coding genes are a focus in molecular thyroid cancer medicine, the impact of oncogenes on the expression of long noncoding RNAs (lncRNAs) has been largely uncharacterized. We aimed to identify the expression patterns of lncRNAs and mRNAs in high-throughput molecular profiles of 18 papillary thyroid cancer (PTC) patients. We identified 452 mRNAs and 240 unannotated lncRNAs that were differentially expressed in PTC...

Representing a novel type of endogenous noncoding RNAs, circular RNAs (circRNAs) have recently gained much attention for their involvement in multiple biological processes. CircRNAs are ubiquitously expressed in eukaryotic cells and modulate gene expression by acting as sponges of microRNAs (miRNAs) or other proteins, such as RNA-binding proteins (RBPs). Due to their unique structure, circRNAs are more stable than linear RNAs. Expression profiles of circRNAs are associated with clinicopathological characteristics of colorectal cancer patients, such as differentiation, TNM classification and distant metastasis...

The pathophysiological function of the forkhead transcription factor FOXN3 remains to be explored. Here we report that FOXN3 is a transcriptional repressor that is physically associated with the SIN3A repressor complex in estrogen receptor-positive (ER+) cells. RNA immunoprecipitation-coupled high-throughput sequencing identified that NEAT1, an estrogen-inducible long noncoding RNA, is required for FOXN3 interactions with the SIN3A complex. ChIP-Seq and deep sequencing of RNA genomic targets revealed that the FOXN3-NEAT1-SIN3A complex represses genes including GATA3 that are critically involved in epithelial-to-mesenchymal transition (EMT)...

Long non-coding RNAs (lncRNAs) have been shown to play important regulatory roles in the pathogenesis and progression of multiple cancers. Here, we investigated the role of long intergenic non coding RNA 319 (linc00319) in the proliferation and invasion of lung cancer cells. We found that, compared with normal lung cell line HBE, linc00319 was increased in low metastatic lung cancer cell lines PAa and AgiY-83a, and further increased in high metastatic lung cancer cell lines A549 and Anip-973. Then, different concentrations of pcDNA-linc00319 expression vector and different concentrations of linc00319 siRNA were respectively transfected into A549 lung cancer cells...

Evidence indicates that long non-coding RNAs (lncRNAs) play a critical role in the regulation of tumor cellular processes, such as proliferation, apoptosis, and metastasis. LncRNA CRNDE (Colorectal Neoplasia Differentially Expressed) is located at human chromosome 16 and has been found overexpressed in a variety of cancers including colorectal cancer (CRC). In this paper, we report that lncRNA CRNDE expression was remarkably upregulated in CRC tissues and that lncRNA CRNDE overexpression was positively correlated with advanced pathological stages and larger tumor sizes...

Long noncoding RNAs (lncRNAs) play roles in the tumorigenesis, proliferation and metastasis of tumor cells. Previous studies indicate that the transcription factor Sp1 is responsible for transcription of the XIAP gene, but it is unknown whether lncRNAs are involved in XIAP transcription. Herein, we identified a novel lncRNA, denoted as XIAP-AS1, transcribed from the first intron of the complementary strand of the XIAP gene. Using RNA FISH, cell fractionation and qRT-PCR, XIAP-AS1 was determined to be located primarily in the nucleus...

The long noncoding RNA, homeobox transcript antisense RNA (Hotair), has been demonstrated to have an important role in regulating various biological processes in various cancers, including hepatocellular carcinoma (HCC). However, the importance of Hotair in HCC proliferation and cell cycle progression remains to be elucidated. In the present study, knockdown of HOTAIR expression by RNA interference inhibited cell proliferation and induced G0/G1 cell cycle arrest in Huh7 hepatocellular carcinoma cells. In addition, the expression levels of CCND1 mRNA and its cyclin D1 protein product were reduced in Huh7 cells following knockdown of HOTAIR...

Reprogramming of cancer cells into induced pluripotent stem (iPSCs) is a compelling idea for inhibiting oncogenesis, especially through modulation of homeobox proteins in this reprogramming process. We examined the role of various long noncoding RNAs (lncRNAs)-homeobox protein HOXA13 axis on the switching of the oncogenic function of bone morphogenetic protein 7 (BMP7), which is significantly lost in the gastric cancer cell derived iPS-like cells (iPSLCs). BMP promoter activation occurred through the corecruitment of HOXA13, mixed-lineage leukemia 1 lysine N-methyltransferase (MLL1), WD repeat-containing protein 5 (WDR5), and lncRNA HoxA transcript at the distal tip (HOTTIP) to commit the epigenetic changes to the trimethylation of lysine 4 on histone H3 in cancer cells...

Accumulating evidences indicate that long noncoding RNAs (lncRNAs) might play important roles in tumorigenesis and metastasis. EMT (epithelial-to-mesenchymal transition) is considered as a critical step in invasion and metastasis of various tumors including bladder cancer (BC). Recent researches have showed that lncRNA H19 is implicated in metastasis through regulating EMT and the reverse MET (mesenchymal-to-epithelial transition). However, underlying mechanisms remain largely unknown. Here, we screened lncRNA and mRNA expression profiles of BC with microarray assay...

Early diagnosis is essential to reduce lung cancer-associated morbidity and mortality rates; however the lack of diagnostic biomarkers for lung cancer has made this difficult. Recent studies have demonstrated that long noncoding RNAs (lncRNAs) serve important roles in cancer occurrence and progression. The present study investigated the novel lncRNA RP11‑713B9.1, which is the antisense transcript of tumor suppressor in lung cancer 1 (TSLC1). The expression levels of RP11‑713B9.1 and TSLC1 in non‑small cell lung cancer were determined using reverse‑transcription quantitative polymerase chain reaction, which revealed that the expression of RP11‑713B9...

The long noncoding RNA highly up-regulated in liver cancer (HULC) is aberrantly elevated in hepatocellular carcinoma (HCC), and this up-regulation is crucial for HCC pathogenesis. However, the underlying mechanism in HULC up-regulation is poorly understood. We hypothesized that HULC might modulate the oncogene high mobility group A2 (HMGA2) to promote hepatocarcinogenesis. Quantitative real-time PCR analysis showed that the expression levels of HULC were positively correlated with those of HMGA2 in clinical HCC tissues...

RNA-binding proteins (RBPs) and noncoding (nc)RNAs (such as microRNAs, long ncRNAs, and others) cooperate within a post-transcriptional network to regulate the expression of genes required for many aspects of cancer behavior including its sensitivity to chemotherapy. Here, using an RBP-centric approach, we explore the current knowledge surrounding contributers to post-transcriptional gene regulation (PTGR) in ovarian cancer and identify commonalities that hint at the existence of an evolutionarily conserved core PTGR network...
