Description
The growth factor interleukin-3 (IL-3) promotes the survival and growth of multipotent hematopoietic progenitors and stimulates myelopoiesis. It has also been reported to oppose terminal granulopoiesis and to support leukemic cell growth through autocrine or paracrine mechanisms. We used kinetic microarray, Northern Blotting and bioinformatics analysis of IL-3 dependent myeloblasts to determine whether IL-3 acts in part by regulating the rate of turnover of mRNA transcripts in specific functional pathways. Our results indicate that exposure of myeloblasts to IL-3 causes immediate early stabilization of hundreds of transcripts in pathways relevant to myeloblast function. Examples include transcripts associated with proliferation and leukemic transformation (pik3cd, myb, pim-1), hematopoietic development (cited2), differentiation control (cdkn1a) and RNA processing (BRF1, BRF2). A domain in the 3-utr of IL-6 that mediates IL-3 responsiveness contains AU-rich elements that bind proteins known to modulate mRNA stability, however a known destabilizing protein (AUF1) is shown not to mediate degradation in the absence of IL-3. These findings support a model of IL-3 action through mRNA stability control and suggest that aberrant stabilization of this network of transcripts could contribute to growth patterns observed in leukemia.

Description
Human erythroblasts purified from cord blood were cultured in vitro and FACS-sorted into five highly purified populations representing distinct differentiation stages: proerythroblasts, early basophilic erythroblasts, late basophilic erythroblasts, polychromatophilic erythroblasts, and orthochromatophilic erythroblasts. The methods for culture and sorting experiments are given in Hu et al. 2013. For each RNA-seq library, RNA was isolated from 1x 106 sorted human erythroblasts using RNeasy Plus Mini kits (Qiagen). Libraries were then prepared using Illumina TruSeqTM RNA kits to obtain 50 nt reads. Collaborators at the New Your Blood Center were responsible for erythroblast culture, FACS purification of erythroblast populations, and acquisition of RNA-seq data. Collaborators at U.C. Berkeley and Lawrence Berkeley National Laboratory performed data analysis and experimental validation of alternative splicing in erythroblasts. Results: Differentiating erythroblasts execute a dynamic alternative splicing program that is enriched in genes affecting cell cycle, organelle organization, chromatin function, and RNA processing. Alternative splicing plays a major role in regulating gene expression to ensure synthesis of appropriate proteome at each stage as the cells remodel in preparation for production of mature red cells. Overall design: Erythroid differentiation stage-specific transcriptome analysis was performed by RNA-seq analysis of highly purified erythroblast populations

Description
Fat intake is an important determinant in the development of obesity. The small intestine is the principal site of digestion and absorption of nutrients, and these short-term circulating nutrients and hormones as well as neural signals derived from the peripheral tissues in responses to a meal act at multiple central nervous system sites where food intake is controlled.

Description
RNA-binding proteins participate in a complex array of post-transcriptional controls essential to cell-type specification and somatic development. Despite their detailed biochemical characterizations, the degree to which each RNA-binding protein impacts on mammalian embryonic development remains incompletely defined and the level of functional redundancy among subsets of these proteins remains open to question. The poly-(C) binding proteins, Pcbp's (aCPs, hnRNPEs), are encoded by a highly conserved and broadly expressed gene family. The two major Pcbp isoforms, Pcbp2 and Pcbp1, are robustly expressed in a wide range of tissues and exert both nuclear and cytoplasmic controls over gene expression. Here we report that Pcbp1-null embryos are rendered nonviable in the peri-implantation stage. In contrast, Pcbp2-null embryos survive until mid-gestation at which time they undergo a loss in viability associated with cardiovascular and hematopoietic abnormalities. Adult mice heterozygous for either Pcbp1 or Pcbp2 null alleles display a mild and non-disruptive growth defect. These data reveal that Pcbp1 and Pcbp2 are individually essential for mouse embryonic development and post-natal growth, reveal a non-redundant in vivo role for Pcpb2 in hematopoiesis, and provide direct evidence that Pcbp1, a retrotransposed derivative of Pcpb2, has evolved essential function(s) in the mammalian genome. Overall design: mRNA-seq on fetal liver tissue from 12.5 days post coitum. 4 replicates of WT and 3 replicates of PCBP2 Knockout

Description
The oviduct is a specialized organ playing crucial roles in the success of early reproductive events and it provides an optimal microenvironment for early embryonic development. However, changes in oviductal environment due to estrus synchronization and superovulation hormonal treatments and subsequent influence on embryos transcriptome profile are not yet investigated. For that, the objective of this study was to investigate differences in developmental rate and transcriptome profile of bovine blastocysts cultured under superovulation or synchronization oviductal environment.
