Project description:Glioblastoma multiforme (GBM) is the most common and aggressive primary human brain tumor. Although comprehensive therapies combining radiotherapy and chemotherapy after surgery can prolong survival, the prognosis is still poor with a median survival of only 14.6 months. Chemoresistance is one of the major causes of relapse as well as poor survival in glioma patients. Therefore, novel strategies to overcome chemoresistance are desperately needed for improved treatment of human GBM. Recent studies have demonstrated that long non‑coding RNAs are closely related to resistance to cancer chemotherapy. Here, we simultaneously detected, for the first time, the expression profiles of mRNAs, lncRNAs, and circRNAs in three pairs of secondary temozolomide-resistant glioblastoma (STRG) and matched primary glioblastoma tissues by microarrays. A total of 92 mRNA, 299lncRNAs, and 53 circRNAs were altered during the Chemoresistance. The functions of these differentially expressed RNAs were predicted by Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. Co-expression networks of lncRNA-mRNA and circRNA-miRNA were conducted to uncovered the hidden ceRNA mechanisms. Our findings revealed the alteration of expression patterns of mRNAs, lncRNAs, and circRNAs in the secondary temozolomide-resistant glioblastoma. These mRNAs, lncRNAs, and circRNAs might be potential therapeutic targets for the treatment of glioblastoma.

Project description:Cross-talk between competitive endogenous RNAs (ceRNAs) may play a critical role in revealing potential mechanisms of tumor development and physiology. Glioblastoma is the most common type of malignant primary brain tumor, and the mechanisms of tumor genesis and development in glioblastoma are unclear. Here, to investigate the role of non-coding RNAs and the ceRNA network in glioblastoma, we performed paired-end RNA sequencing and microarray analyses to obtain the expression profiles of mRNAs, lncRNAs circRNAs and miRNAs. We identified that the expression of 501 lncRNAs, 1789 mRNAs, 2038 circRNAs and 143 miRNAs were often altered between glioblastoma and matched normal brain tissue. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed on these differentially expressed mRNAs and miRNA-mediated target genes of lncRNAs and circRNAs. Furthermore, we used a multi-step computational framework and several bioinformatics methods to construct a ceRNA network combining mRNAs, miRNAs, lncRNAs and circRNA, based on co-expression analysis between the differentially expressed RNAs. We identified that plenty of lncRNAs, CircRNAs and their downstream target genes in the ceRNA network are related to glutamatergic synapse, suggesting that glutamate metabolism is involved in glioma biological functions. Our results will accelerate the understanding of tumorigenesis, cancer progression and even therapeutic targeting in glioblastoma. We hope to inspire researchers to study the role of non-coding RNAs in glioblastoma.

Project description:Subcutaneous preadipocyte differentiation play a critical role in fat deposition of pigs. However, the action of different RNAs in subcutaneous preadipocyte differentiation, such as messenger RNAs (mRNAs), long noncoding RNAs (lncRNAs), and circular RNAs (circRNAs), are still largely unclear. In the present study, a transcriptome analysis including mRNAs, lncRNAs, and circRNAs was performed in different stages of D0, D2, D4, and D8 using RNA-seq technology. Our results identified 1,554, 470, 1,344, 1,777, and 676 differentially expressed (DE) mRNAs, 112, 58, 95, 136, and 93 DE lncRNAs, and 902, 787, 710, 932, and 850 DE circRNAs between D2 and D0, between D4 and D2, between D8 and D4, between D4 and D0, and between D8 and D0, respectively. Moreover, functional enrichment analysis showed that the common DE mRNAs during entire differentiation were mainly involved in lipid metabolic and cell differentiation processes. Additionally, co-expression network analysis identified the potential lncRNAs related to adipogenesis, e.g., MSTRG.42239 and MSTRG.146410. Taken together, this study provides a genome-wide landscape of RNA expression profiles during subcutaneous preadipocyte differentiation, thus improving our understanding of molecular mechanism in regulating subcutaneous adipogenesis of pigs.

Project description:Idiopathic short stature is diagnosed by a standing height of less than two standard deviation scores in a specific population adjusted for age and gender and the exclusion of identifiable diseases. A series of studies have confirmed that noncoding RNAs can regulate the chondrocyte proliferation, hypertrophy, and endochondral ossification in the growth plate. In order to analyze and find differentially expressed ceRNAs (lncRNAs, circRNAs and mRNAs in peripheral blood exosomes of idiopathic short stature and healthy controls, we aimed to explore whether differentially expressed ceRNAs (lncRNAs, circRNAs and mRNAs) in peripheral blood exosomes of idiopathic short stature. Three pairs of peripheral blood exosomes samples were subjected to microarray analysis using the SBC human ceRNA Microarray.

Project description:Long noncoding RNAs (lncRNAs) and circular RNAs (circRNAs), which were proved to play a crucial role in regulating cell differentiation and tissue development. However, the expression profiles of different RNAs, such as mRNA, lncRNAs, and circRNAs in different adipose tissues, are still largely unclear. To shed light on this issue, we performed the systematic analysis of mRNAs, lncRNAs, and circRNAs obtained from intramuscular adipose tissues (IAT), subcutaneous adipose tissues (SAT), visceral adipose tissues (RPAT), and mesenteric adipose tissues (MAT) tissues of Chinese Erhualian pigs using high-throughput sequencing. A total of 1,695, 1,878, 494, 1,300, 902, and 355 differentially expressed (DE) mRNAs, 318, 399, 192, 251, 249, and 347 DE lncRNAs, 1,367, 1,007, 999, 1,153, 1,256, and 837 DE circRNAs were identified in IAT versus SAT, IAT versus RPAT, SAT versus RPAT, MAT versus IAT, MAT versus SAT, and MAT versus RPAT, respectively. Gene ontology (GO) enrichment analyses showed these DE genes were mainly involved in lipid metabolic and immune response. Next the co-expression network construction of mRNAs-lncRNAs revealed several key lncRNAs such as MSTRG.604204 and MSTRG.604206 might associated with lipid metabolic. Tissue specific analysis indicated that circRNA exhibited the highest tissue specificity than lncRNA and mRNA, and the IAT had the most tissue specific lncRNA, mRNA, and circRNA compared with other tissues. Taken together, this study gives us a novel clue to the role of mRNAs, lncRNAs and circRNAs in fat metabolism, thus improving our understanding of the regulation mechanism of different gene expression profiles in adipose deposition

Project description:Background: Cryptosporidium baileyi is the most common Cryptosporidium species in birds. However, effective prevention measures and treatment for C. baileyi infection were less understood. Long non-coding RNA (lncRNA) and circular RNA (circRNA) were discovered to play an important role in regulating occurrence and progression of many diseases and identified as effective biomarkers for diagnosis and prognosis of several diseases. In the present study, the expression profiles of mRNA, lncRNA and circRNA associated with C. baileyi infection were investigated for the first time. Results: The tracheal tissues of experimental (C. baileyi infection) and control chickens were collected for deep RNA sequencing, and 545,479,934 clean reads were obtained. Of them, 1376 novel lncRNAs were identified, including 1161 long intergenic non-coding RNAs (lincRNAs) and 215 anti-sense lncRNAs. 124 lncRNAs were found to be significantly differentially expressed between experimental and control groups. Additionally, 14,698 mRNAs and 9085 circRNAs were identified, and significantly different expressions were observed for 1317 mRNAs and 104 circRNAs between two groups. The gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis of their targets and background genes suggested that these dysregulated genes would be involved in the interaction between host and C. baileyi. Conclusions: The present study firstly provides the expression profiles of mRNAs, lncRNAs and circRNAs during C. baileyi infection, and describes a novel perspective on the potential roles of lncRNAs and circRNAs underlying the pathogenesis mechanism of Cryptosporidium infection.
