ABSTRACT: Long noncoding RNA profile in the mouse plasma after ischemia-reperfusion injury (IRI). In the study presented here, we mixed the plasma from three mouse after IRI and identified the genome-wide expression level of lncRNAs.
Project description:A total of 3 patients with basal cell carcinoma (BCC) and 3 healthy individuals (control; non-lesional skin) were enrolled in the study. Punch biopsies (4 mm) were obtained under local anaesthesia and immediately put in RNAlater (Qiagen, Hilden, Germany) and stored at - 80 °C until RNA extraction. The lncRNA and mRNA expression in BCC was compared to lncRNA and mRNA expression in non-lesional skin (control).
Project description:The expression of lncRNAs in cutaneous squamous cell carcinoma (cSCC) were determined with a commercially available microarray (Arraystar Inc.,Rockville, Maryland USA). The Arraystar human lncRNA Microarray V3.0 containing 30,586 LncRNAs and 26,109 coding transcripts (mRNAs) A total of three patients with cSCC were biopsied. A total of three control (non-lesional skin) were biopsied.
Project description:Epithelial ovarian cancer (EOC) constitutes a major gynecological malignancy, with a reported incidence rate of 3-12/100 000 woman annually. As early symptoms of ovarian cancer are often clinically atypical or absent, the majority of ovarian cancer patients are diagnosed at a late stage, when the five-year survival rate is extremely low. This condition underscores the urgency of early detection of these patients and establishment of new therapeutic targets for successful intervention. Considering that the predominant biological characteristic that differentiates malignant from benign tumors is the ability to metastasize, it is necessary to identify novel metastasis-related molecules for ovarian cancer. In this study, we found that CAFs could significantly increase the metastatic potential of ovarian cancer cells compared with non-cancer associated fibroblasts(NAFs), which is associated with over-expression of CXCL14 in CAFs. We examined the impact of CAF-secreted CXCL14 on the lncRNA expression profiles in ovarian cancer during metastasis. We treated A2780s ovarian cancer cell line with recombinant CXCL14 protein and control respectively and subjected them to Arraystar Human LncRNA microarray v3.0 to profile differential lncRNAs in ovarian cancer upon treatment of CXCL14
Project description:Long noncoding RNA profile in the heart, whole blood, and plasma before and heart failure (HF). In the study presented here, we mixed the five pairs of mouse hearts, whole blood, and plasma before and after HF and identified the genome-wide expression level of lncRNAs.
Project description:Long noncoding RNA profile in the liver after ischemia-reperfusion injury (IRI). In the study presented here, we mixed the three mouse livers after IRI and identified the genome-wide expression level of lncRNAs.
Project description:As the application of carbon nanotubes (CNT) in consumer products continues to rise, studies have expanded to determine the associated risks of exposure on human and environmental health. In particular, several lines of evidence indicate that exposure to multi-walled carbon nanotubes (MWCNT) could pose a carcinogenic risk similar to asbestos fibers. However, to date the potential markers of MWCNT exposure are not yet explored in humans. Global mRNA and lncRNA expression profiles in the whole blood of exposed workers, having direct contact with MWCNT aerosols for atleast 6 months (n=8), were compared with expression profiles of non-exposed (n=7) workers (e.g., proffessional and/or technical staff) from the same manufacturing facility.
Project description:To date, 481 transcribed ultraconserved regions (T-UCRs) have been discovered in human genome. We aimed to investigate their characteristics in Crohnâs disease (CD) with conparison to healthy normal controls, to reveal differentially expressed T-UCRs. 3 CD patients and 3 NC volunteers were recruited in this study. With colonoscopy, colon mocosa pinch biopsy samles were got at inflammed site in CD patients and normal sites in NC volunteers respectively.
Project description:Pancreatic tumors with small size can cause type3C Diabetes Mellitus (PCA-DM) but the mechanism is unknown. In this study we aimed at revealing the mRNA and long noncoding RNA (LncRNA) expression patterns of pancreatic tumors that triggered PCA-DM. Four pancreatic tumors from patients with PCA-DM (A1-A4), four pancreatic tumors from patients without PCA-DM (B1-B4), and four pancreatic tissues from patients with pancreatitis were individually profiled with Agilent microarrays(Arraystar Human LncRNA Array v3.0). Pancreatic tumors with PCA-DM or without PCA-DM, and pancreatic tissues of pancreatitis were individually profiled.
Project description:Non-alcoholic fatty liver disease (NAFLD) is a common liver disorder and affects approximately one third of the general population.Recent studies have shown that long non-coding (lncRNA) plays critical roles in a myriad of biological processes and human diseases,Since the roles of lncRNA in NAFLD remain unknown,they were investigated in the study.Our findings indicate that the expression profiles of lncRNAs has changed in NAFLD as compared with normal liver, and may provide novel insight into the molecular mechanism underlying the disease and potential novel diagnostic or therapeutic targets for NAFLD. Microarray expression profiling of mRNAs and lncRNAs were conducted using RNA extracted from five NAFLD liver tissues and five normal liver samples.
Project description:To identify the novel tumor suppressors in hepatocellular carcinoma (HCC), we have employed whole genome microarray expression profiling as a discovery platform in HCC and paired normal liver tissues to identify genes which down-regulated in HCC. Among which, INTS6 and its pseudogene, namely INTS6P1, were found to be dramatically down-regulated in HCC. The down-regulated expression of INTS6 and INTS6P1 in HCC was further confirmed by real-time PCR. RNA was extracted from 3 pairs of HCC and normal liver tissue harvested from patients to undergo microarray study.
