1. 1. Molecular Insights into Kcnq1ot1 Noncoding Antisense RNA Mediated Long Range Transcriptional Gene Silencing

   Författare :Radha Raman Pandey; Chandrasekhar Kanduri; Karl Ekwall; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; epigenetics; gene silencing; noncoding RNA; genomic imprinting; Kcnq1ot1; Medical genetics; Medicinsk genetik;

   Sammanfattning : Non-coding antisense RNAs have been implicated in the epigenetic silencing of individual gene as well as chromosomal domains. While silencing of the overlapping gene by antisense RNAs has been well investigated, their functional role in silencing of chromosomal domains remains enigmatic. LÄS MER

3. 2. Epigenetic Regulation by Noncoding RNA

   Författare :Tanmoy Mondal; Chandrasekhar Kanduri; Jérôme Cavaillé; Uppsala universitet; []
   Nyckelord :Genomic Imprinting; Noncoding RNA; Epigenetics; DNA methylation; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

   Sammanfattning : High throughput transcriptomic analyses have realized us with the fact that eukaryotic genome encodes thousands of noncoding RNAs (ncRNAs) with unknown function. In my thesis, I sought to address epigenetic regulation of transcription by ncRNA using the Kcnq1 imprinted cluster as a model system. LÄS MER

4. 3. Long Noncoding RNA Mediated Regulation of Imprinted Genes

   Författare :Faizaan Mohammad; Chandrasekhar Kanduri; Kristian Helin; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Genomic imprinting; noncoding RNA; epigenetics; chromatin; DNA methylation; Developmental biology; Utvecklingsbiologi; Molecular biology; Molekylärbiologi; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

   Sammanfattning : Genomic imprinting is an epigenetic phenomenon that causes a subset of mammalian genes to be expressed from only one allele in a parent-of-origin manner. The defects in the imprinting regulation result in disorders that affect development, growth and metabolism. LÄS MER

5. 4. Regulatory Roles of Noncoding RNA in Development and Disease

   Författare :Gaurav Kumar Pandey; Chandrasekhar Kanduri; Claes Wadelius; Karl Ekwall; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Noncoding RNA; Genomic Imprinting; Epigenetics; Neuroblastoma;

   Sammanfattning : Long noncoding RNAs (lncRNAs) are being realized as important players in gene regulation and their misregulation has been considered as one of the underlying causes for tumor initiation and progression in many human pathologies. In the current thesis, I have addressed the functional role of lncRNAs in development and disease model systems. LÄS MER

7. 5. Long-range Control of Gene Expression by Imprinting Control Regions During Development and Neoplasia

   Författare :Noopur Thakur; Chandrasekhar Kanduri; Thomas Ekstrom; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Genomic imprinting; Imprinting control region; Antisense RNA; de novo methylation; Molekylärbiologi; Molecular biology; Molekylärbiologi;

   Sammanfattning : Genomic imprinting is an epigenetic phenomenon by which a subset of genes is expressed in a parent of origin specific manner. Most of the imprinted genes are located in clusters. Genetic evidences suggest that genes in imprinted clusters are regulated by Imprinting Control Regions (ICRs). LÄS MER
