The rat lncRNA microarray analysis of the 8 samples from control and NNK treatment group

ABSTRACT: In order to assess the alteration in lncRNA expression in rat lung carcinogenesis induced by NNK, we determined the lncRNA expression profiles in 3 rat lung tumor samples and matched normal lung tissues and 2 blood samples from the control and NNK treatment group in the 95th week using Arraystar Rat lncRNA Microarray.

We induced lung cancer using 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) in a rat model and determined the lncRNA expression profiles in lung cancer tissues and rat blood samples.

Transcriptional responses to NNK and selenocystine in mouse lungs.

Project description:This study evaluated transcriptional effects of the lung carcinogen NNK ( 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone) injection and selenocystine consumption on the murine lung. Female A/J mice at 5 weeks of age were obtained from The Jackson Laboratory. Animals were stabilized on an unsupplemented AIN-76 diet for one week prior to being given the selenium supplemented diet. The basal level of selenium in the diet is 0.35 ppm Se, the selenocytine supplemention was at 15 ppm. NNK was administered i.p. as a single 10 uM injection in 0.2 mL saline. With this protocol, 100% of animals reproducibly develop lung tumors after 3 months. Three days after NNK administration, animals were provided AIN-76A diets supplemented with selenocystine at 15 ppm selenium ad libitum for 10 days. Animals were sacrificed thirteen days after NNK administration. Lung tissue was harvested, immediately homogenized in Trizol and frozen. The organic extracted RNAs were run over Qiagen RNeasy columes before quantifying and qualifying them. All samples had RNA quality index's greater than 9. Four groups of A/J mice were utilized with 4 biological replicates per group. 1) Untreated - controls on the AIN-76 diet (0.35 ppm Se). 2) NNK treated - single injection of NNK, maintained on norma AIN-76 diet, sacraficed after 13 days. 3) SECY - selenocystine supplemented (15 ppm) for 10 days on a AIN-76 diet then sacraficed. 4) NNK plus SECY - single injection of NNK, after 3 days, selenocystine supplemented (15 ppm) diet for 10 days then sacraficed. RNAs from the the four untreated mice were combined to phenotypically anchor the dual color expression profile. mouse lung responses to NNK injection and/or selenocystine dietary supplementation

LncRNA Expression Profiling in sinonasal squamous cell carcinomas

Project description:Long non-coding RNAs (lncRNAs) play important roles in various biological progresses of carcinogenesis. However, the function of lncRNAs in human sinonasal squamous cell carcinoma (SNSCC) remains greatly unclear. In the current study, lncRNA AC091729.7 expression was examined in SNSCC samples by using microarray.The human 8 × 60 K lncRNA array was produced by Arraystar Company (USA). Over 25,000 lncRNAs were gathered from the canonical data sources encompassing UCSC, NCBI RefSeq, RNAdb, and NRED.

RNA-sequencing of lung tissues from Gprc5a-/- and Gprc5a-/-/Lcn2-/- mice at baseline and seven months post-NNK

Project description:We have shown that Gprc5a-/- mice form Kras-mutant lung tumors spontaneously which is accelerated by tobacco carcinogen (NNK) exposure. We found in these mice that Lcn2 was distinctively up-regulated along the spectrum of Kras-mutant lung cancer development. To understand the role of Lcn2 in lung cancer pathogenesis, we generated Gprc5a-/-/Lcn2-/- mice and found that these animals have increased lung tumor devleopment following NNK compared to Gprc5a-/- animals with intact Lcn2. To understand these effects, we performed RNA-sequencing (RNA-Seq) of lung tissues from Gprc5a-/-/Lcn2-/- and Gprc5a-/- mice at baseline (prior to NNK exposure) and of tumor-bearing lungs from both groups at seven months post-NNK exposure.

Chimeric RNA RRM2-C2orf48 plays an oncogenic role in the development of NNK-induced lung cancer

Project description:Chimeric RNAs have been used as biomarkers and therapeutic targets for multiple types of cancers. However, less attention has been paid to their mechanism of action in neoplasia. Here, we report that chimeric RNA RRM2-C2orf48 promotes 4-(methyl nitrosamine)-1-(3-pyridinyl)-1-butanone (NNK)-induced lung cancer. We found that RRM2-C2orf48 had higher expression levels in lung cancer cell lines and in lung cancer tissues from 74 patients than in normal cells and tissues, respectively. And its expression level was correlated with smoking. Next, we demonstrate that the expression level of RRM2-C2orf48 could increase after treatment with 200 mg/L NNK for 24 h. Overexpressing RRM2-C2orf48 accelerated the process of NNK-induced lung cancer and promoted cell growth. Meanwhile, suppressing RRM2-C2orf48 inhibited cell growth. Finally, we identified miR-219a-2-3p as a potential target of RRM2-C2orf48. In summary, RRM2-C2orf48 accelerated the process of NNK-induced lung cancer and miR-219a-2-3p may be involved in this process.

Project description:We have previously shown that Gprc5a-KO mice develop lung tumors that are accelerated by exposure to the tobacco-specific carcinogen NNK. In this study we sought to understand the temporal evolution of gene expression changes in tumors and normal-appearing tissues.

Bladder cancer lncRNA expression profiling

Project description:Using the highly sensitive lncRNA array, we screened the lncRNAs abundant in the human bladder cancer and Adjacent normal bladder tissues, and the function of differentially expressed lncRNAs were analyzed by bioinformatics. The Arraystar Human lncRNA Array (8x15K, Arraystar) and whole human mRNA Array (4x44K, Arraystar) and was used to profile differentially expressed lncRNAs and genes in bladder cancer vs. normal tissues following the manufacturerâs instructions. Briefly, extracted RNA template (1mg) was reversely transcribed into cDNA and digested into fragments with endonucleases. These fragments were labeled with DNA labeling reagent and labeled cDNAs were hybridized to the microarray via incubation at 45Â°C and rotated at 60 rpm for 17 h. Following washing and staining, the arrays were scanned using a GeneChip Scanner3000 with GeneChip Operating Software.
