BACKGROUND P73 antisense RNA 1 T (non-protein coding), also known as TP73-AS1, is a long non-coding RNA (lncRNA) which is involved in cell proliferation and the development of tumors. However, the exact effects and molecular mechanisms of TP73-AS1 in hepatocellular carcinoma (HCC) progression are still unknown. The present study is aimed to investigate the detailed functions and the mechanism o...

PURPOSE To report the identification of five novel nonsense mutations in the zinc finger E-box binding homeobox 1 (ZEB1) gene and exclusion of promoter region mutations in individuals without ZEB1 coding region mutations in posterior polymorphous corneal dystrophy (PPCD). METHODS Slit-lamp examination and DNA collection were performed for individuals diagnosed with PPCD and, when available, a...

Altered expression of long noncoding RNAs (lncRNAs) associated with human carcinogenesis. We performed a cDNA microarray analysis of lncRNA expression in 12 cases of nasopharyngeal carcinoma (NPC) and 4 non-tumor nasopharyngeal epitheliums. One lncRNA, actin filament associated protein 1 antisense RNA1 (AFAP1-AS1), was identified and selected for further study. AFAP1-AS1 expression was upregula...

LincRNA FEZF1-AS1 has been identified to exert oncogenic functions in various biological processes of tumorigenesis. However, the function of FEZF1-AS1 in lung adenocarcinoma still remains unclear. Our findings revealed that FEZF1-AS1 was increased in lung adenocarcinoma tissues and cell lines and high level of FEZF1-AS1 was associated with poor prognosis of lung adenocarcinoma. Functional expe...

Many long noncoding RNAs have been reported to play pivotal roles in cancer biology. Among them, the long noncoding RNA ZNFX1-AS1 has been confirmed to function in breast cancer progression, but the role of ZNFX1-AS1 in hepatocellular carcinoma (HCC) growth and the related molecular mechanisms still remains unknown. In the present study, we first identified the expression of ZNFX1-AS1 in HCC pa...

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 compleme...

The human DHRS4 gene cluster consists of DHRS4 and two immediately downstream homologous genes, DHRS4L2 and DHRS4L1, generated by evolutionarily gene-duplication events. We previously demonstrated that a head-to-head natural antisense transcript (NAT) of DHRS4, denoted DHRS4-AS1, regulates all three genes of the DHRS4 gene cluster. However, it is puzzling that DHRS4L2 and DHRS4L1 did not evolve...

Increasing evidence indicates that long non-coding RNAs (lncRNAs) can act as crucial regulators of tumor progression. In the present study, UXT-AS1 was found to be significantly upregulated in colorectal cancer (CRC) and high expression levels of UXT-AS1 were significantly associated with poor prognosis in CRC patients. In addition, upregulation of UXT-AS1 resulted in inhibition of cell apoptos...

Aim: To explore the expression and clinical significance of Zeb1 and Zeb2 in osteosarcoma (OS). Materials and methods: In our study, we detected the expression of Zeb1 and Zeb2 in 120 cases of OS tissues with immunohistochemistry, and divided the cohort into Zeb1 or Zeb2 high/low expression group according to the cut-off. Moreover, we evaluated the clinical significance of Zeb1/Zeb2 by analyzin...
