Project description:The purpose of this experiment is to characterize changes in the transcriptome and epigenome in diet-associated liver cancer. For that we used the DIAMOND mice as a model organism and performed RNA-seq and H3K27Ac and H3K27Me3 ChIP-seq in livers from control mice (fed with a regular diet) and livers and tumours from western diet fed mice.

Project description:We analyzed the transcriptional effects of transgenic expression of our erythroid-specific codon-optimized GATA1 lentiviral vector in differentiating red blood cells of patients diagnosed with Diamond-Blackfan anemia.
Project description:Gene expression analysis from erythroid progenitors (CD34+/CD71(high)/CD45- mononuclear cells from the bone marrow) of patients with Diamond-Blackfan anemia (due to RPS19 mutations) and control individuals.
Project description:Giardia lamblia is a protozoan parasite that is found worldwide and has both medical and veterinary importance. We applied the transcription start sequence (TSS-seq) and RNA sequence (RNA-seq) techniques to study the transcriptome of the assemblage A WB strain trophozoite. We identified 8000 transcription regions (TR) with significant transcription. Of these regions, 1881 TRs were more than 500 nucleotides upstream of an annotated ORF. Combining both techniques helped us to identify 24 ORFs that should be re-annotated and 60 new ORFs. From the 8000 TRs, we were able to identify an AT-rich consensus that includes the transcription initiation site. It is possible that transcription that was previously thought to be bidirectional is actually unidirectional.
Project description:To better understand the tumorigenesis and metastasis of human metastatic melanoma(MM) , we analyzed the transcriptomes of three cell lines that represent the three distinct stages of MM pathogenesis: the normal stage (HEMn), the onset of MM (A375), and the metastasis stage (A2085). Using the next generation sequencing (NGS) technology, we detected unsymmetrical expression of genes particularly in Chr9, 12, and 14 among three cell lines, an indication of the involvement of these genes in the tumorigenesis and metastasis of MM. These genes were assigned into 41 categories by their expression patterns and their biological functions were subsequently analyzed by Ingenuity Pathway Analysis software. In the top category associated with cancer, HIF1A, IL8, TERT, ONECUT1 and FOXA1 had direct interaction with the transcription factors or cytokines known to be involved in the tumorigenesis or metastasis in other malignant tumors. Our findings suggest that pathway about cytokines regulation in macrophages may play a more prominent role in the pathogenesis of MM. This study provides not only new targets for downstream mechanistic studies in the tumorigenesis and metastasis of MM, but also a new strategy to study the progression of other malignant cancers.

Project description:Calorie restriction (CR), which is a factor that expands lifespan and an important player in immune response, is an effective protective method against cancer development. Thymus, which plays a critical role in the development of the immune system, reacts to nutrition deficiency quickly. RNA-seq-based transcriptome sequencing was performed to thymus tissues of MMTV-TGF-? mice subjected to ad libitum (AL), chronic calorie restriction (CCR), and intermittent calorie restriction (ICR) diets in this study. Three cDNA libraries were sequenced using Illumina HiSeq™ 4000 to produce 100 base pair-end reads. On average, 105 million clean reads were mapped and in total 6091 significantly differentially expressed genes (DEGs) were identified (p < 0.05). These DEGs were clustered into Gene Ontology (GO) categories. The expression pattern revealed by RNA-seq was validated by quantitative real-time PCR (qPCR) analysis of four important genes, which are leptin, ghrelin, Igf1, and adinopectin. RNA-seq data has been deposited in NCBI Gene Expression Omnibus (GEO) database (GSE95371). We report the use of RNA sequencing to find DEGs that are affected by different feeding regimes in the thymus.
