the expression profile and clinical value of circRNAs in lung adenocarcinoma

Project description:Circular RNAs (circRNAs) play important roles in tumorigenesis, including lung cancer. However, the expression profile and clinical value of circRNAs in lung adenocarcinoma remains unclear. This study aimed to establish the circular RNA expression profile of lung adenocarcinoma tissue and determine its potential diagnostic and prognostic value.

Microarray expression profile analysis of circular RNAs in human pancreatic ductal adenocarcinoma

Project description:To explore the potential involvement of circular RNAs (circRNAs) in pancreatic ductal adenocarcinoma (PDAC) oncogenesis, we conducted circRNA profiling in six pairs of human PDAC and adjacent normal tissue by microarray. Our results showed that clusters of circRNAs were aberrantly expressed in PDAC compared with normal samples, and provided potential targets for future treatment of PDAC and novel insights into PDAC biology. Analyze circular RNA expression in pancreatic ductal adenocarcinoma (PDAC) by microarray platform.

CircRNA expression profiles in early stage lung adenocarcinoma

Project description:To determine the circRNA expression profile in early stage lung adenocarcinoma and matched non-tumor tissues, we used circRNA microArray analysis form Arraystar to examine the expression of circRNAs Lung adenocarcinoma, a form of NSCLC with high lethality at advanced stage, is becoming more popular in women, non- or never-smokers, and even young adult. However, there are no effective early diagnosis methods at present for patients to cure timely. Circular RNAs (circRNAs) as a special novel, stable, and conserved non-coding RNA in mammalian cells have been reported to be widely involved in the processes of cancer disease. Yet, it is still a puzzle which specific circRNAs are involved in the development of early stage lung adenocarcinoma. Here, tumour samples and paired adjacent normal tissues from 4 patients with early stage lung adenocarcinoma were selected for investigating the expression profile of circRNAs by using the high-throughput circRNA microarray. Bioinformatic analyses were conducted to screen those differentially expressed circRNAs. This work illustrates that clusters of circRNAs are aberrantly expressed in early stage lung adenocarcinoma, which might be able to provide potential targets for the early diagnosis of this disease and new genetic insights into lung cancer.

The profile of circular RNA in hypoxic exosomes from lung adenocarcinoma cell line

Project description:Hypoxia is a common feature of solid tumors and is associated with aggressiveness and poor prognosis of patients. Exosomes are involved in mediating cellular environment interactions. circRNAs are a class of non-coding RNAs (ncRNAs) broadly expressed in cells and exosomes. However, in lung adenocarcinoma tumor development, functions and regulatory mechanisms of exosomal circ-RNAs induced by hypoxia remain poorly understood.To further explore the differences in recombinant RNA expression in hypoxic and normoxic exosomes derived from lung adenocarcinoma cell line

Comprehensive profile and contrastive analysis of circular RNA in cervical squamous carcinoma and adenocarcinoma

Project description:To contrastively analyze the expression pattern of circRNAs in cervical squamous carcinoma, adenocarcinoma and adenosquamous carcinoma variants. CircRNAs expression in cervical squamous carcinoma, adenocarcinoma and adenosquamous carcinoma tissues together with the adjacent normal tissues were profiled by high-throughput RNA sequencing.

Expression profile and potential function of circRNAs in peripheral blood mononuclear cells from patients with primary gout

Project description:To determine the expression profile and clinical significance of circular RNAs (circRNAs) in peripheral blood mononuclear cells (PBMCs) of patients with primary gout and healthy control subjects. Human circRNA microarrays were used to identify the differentially expressed circRNAs in primary gout (Gout, n = 5) and healthy subjects (HC, n = 3). Bioinformatics analyses were performed to predict the roles of differently expressed circRNAs. Quantitative real-time polymerase chain reaction (qRT-PCR) was applied to validate the results in 90 gout patients, and 60 healthy control subjects (HC). Microarray analysis indicated that 238 circRNAs were up-regulated and 41 circRNAs were down-regulated in the Gout group (Fold change>1.5, p-value<0.05). Bioinformatics analysis showed that differentially expressed circRNAs were involved in the pathogenesis of gout through a variety of different pathways. Significant association was observed between these circRNAs and lipid metabolism indicators. Our results provide novel insight into the mechanisms of primary gout, and reveal that hsa_circRNA_103657 could effectively discriminate the gout group and the healthy control groups.

CircRNAs in Arabidopsis thaliana across the lifespan

Project description:To explore the overall circRNAs involved in growth and development of Arabidopsis thaliana across the lifespan, we deeply sequenced samples of whole plants from different developmental stages (cotyledons emergence, rosette leavesï¹¥1 mm, rosette growth complete, first flower open, flourishing florescence, first silique shattered, senescence). The total RNA was purified by rRNA-depletion and linear RNA removal with RNAseR, and sequenced by the Illumina HiSeq2500 platform. We obtained 31 Gb raw data and identified 1217 circRNAs with expression quantity. We annotated these circRNAs and predicted their targeted microRNA. The circRNAs involved in growth and development of Arabidopsis thaliana across lifespan were identified and analyzed using the Illumina HiSeq2500 platform.
