Book Description
Genomic imprinting, a unique epigenetic regulation resulting in a parent-of-origin specificgene expression, is essential for normal mammalian development and growth. H19 is amaternally expressed long non-coding RNA that is a central regulator of the imprinting gene network controlling development and growth. H19 is expressed throughout embryonic development in multiple tissues including all hematopoietic cells. The role of H19 during embryonic development has only been documented for the placenta where it controls growthand the role of H19 in lymphopoiesis has not been investigated. The laboratory has previouslyfound H19 as the major differentially expressed transcript in two microarrays comparing fetalliver (FL) and bone marrow (BM) derived pro-B cells, as well as between early and latethymic settling progenitors. However, a role for imprinting gene H19 in B cell development,or even in immune system remains elusive. Here we sought to analyze mice where a large segment of the H19 locus has been deleted. In our work, we found that loss of H19 have specific impact on the FL B cell development byproducing increased numbers of BP1+ proB cell. Although BP1+ proB cells from H19-/- FLshowed impaired Ig heavy chain V-D-J rearrangement, that increase resulted in a net enlarged B cell compartment in the adult periphery of H19 mutant. In adult mice, although H19 is notexpressed in B lymphocytes after birth, B cells from H19-/- mice exhibited altered B cellsurface phenotype, represented by an upregulated B220 expression on all B cell subsets. After immunization with different T cell dependent antigens, H19-/- exhibits reduced GC B cells, and impaired specific IgM titer in the serum, indicating a defected B cell response in H19-/-mice. Competitive reconstitution analysis showed a B cell autonomous impairment in the Bcell response. Consistently we found a reduced BCR responsiveness of H19-/- naïve B cells that together with less efficient upregulation of MHCII and CD40 expression after immunization might be responsible for the impaired immune response in H19-/- mice. Genome-wide transcription analysis revealed differential expression of genes involved inregulating the intensity of B cell receptor signaling. This work brings new insights on the regulation role of long non-coding RNA H19 in the early B cell development and immune system.

Book Description
The study in this thesis mainly focus on understanding the regulatory roles of LncRNA H19 in the muscle and liver. In order to better understand the role of H19 in muscle differentiation, we utilized RNA-seq to compare the differential gene expression between control and H19 knockdown cells during C2C12 myoblast differentiation. This study can lead us to identify candidate genes that are regulated by H19 during muscle differentiation. We also found that H19 plays an important role in the liver through regulating hepatic glucose production (HGP), which is a major contributor to hyperglycemia in type-2 diabetes (T2D). Results from our study revealed a novel epigenetic mechanism utilized by LncRNA H19 in regulating HGP in both normal and pathological conditions.

Book Description
The immune system is comprised of diverse cell types that work together to protect the host from infection and maintain tissue homeostasis. To achieve this complex balance, extracellular cues determine highly specific epigenetic landscapes and transcriptional profiles of each immune cell subtype. New evidence indicates that long non-coding RNAs (lncRNAs) play critical roles in epigenetic and transcriptional regulation in mammals. Here we identify the lncRNA Morrbid, and examine its role in immune function. In Chapter 2, we assess the function of Morrbid at homeostasis and describe its role in finely tuning the lifespan of short-lived myeloid cells. In Chapter 3, we examine Morrbid under inflammatory conditions and illustrate its role in restraining CD8 T cell responses following viral infection. These data demonstrate that lncRNAs can function as highly cell-type specific effectors of extracellular cues to control immunological processes that require rapid and strict regulation.

Book Description
This book offers a comprehensive and detailed overview of various aspects of long non-coding RNAs. It discusses their emerging significance in molecular medicine, ranging from human cancers to cardiovascular and metabolic diseases. Transcriptomic studies have demonstrated that the majority of genomes found in complex organisms are expressed in highly dynamic and cell-specific patterns, producing huge numbers of intergenic, antisense and intronic long non-protein-coding RNAs (lncRNAs). Thousands of lncRNAs have been identified, and unlike mRNA, they have no protein-coding capacity. A large repertoire of ncRNAs, actively transcribed from the mammalian genome, control diverse cellular processes, both in terms of development and diseases, through a variety of gene regulatory mechanisms. IncRNAs have emerged as a new paradigm in epigenetic regulation of the genome. Given its scope, the book will be of particular interest to molecular, chemical, cell and developmental biologists, as well as specialists in translational medicine involved in disease-oriented research. It also offers a valuable resource for in silico experts seeking a deeper understanding of lncRNA expression and function through computational analysis of the NGS data.
