Comparison of reticulocytes from adult peripheral blood and umbilical cord blood. Hemoglobin (Hb) composition switches around the time of birth from fetal Hb to adult Hb. Together with microRNA profiling, results provide insight into the role of microRNAs in fetal-to-adult Hb switching.

(Submitter supplied) RNA from circulating blood reticulocytes was utilized to provide a robust description of genes transcribed at the final stages of erythroblast maturation. After depletion of leukocytes and platelets, Affymetrix HG-U133Plus 2.0 arrays were hybridized with probe from total RNA isolated from blood sampled from 6 umbilical cords and 6 healthy adult humans.

(Submitter supplied) MicroRNA are ~22nt-long small non-coding RNA that negatively regulate protein expression through mRNA degradation or translational repression in eukaryotic cells. Based upon their importance in regulating development and terminal differentiation in model systems, erythrocyte microRNA profiles were examined at birth and in adults to determine if changes in their abundance coincide with the developmental phenomenon of hemoglobin switching. more...

(Submitter supplied) MicroRNAs (miRNAs) are small non-coding RNAs (sncRNAs) crucial for post-transcriptional and translational regulation of cellular and developmental pathways. Study of miRNAs in erythropoiesis thus elucidates the process and facilitates diagnosis and therapy development for related disorders. Here, we used high-throughput DNA Nanoball small RNA sequencing to characterise sncRNAs, and in particular miRNAs, comprehensively in human erythroid cell cultures. more...

(Submitter supplied) The liver is a multifunctional organ, which undergoes rapid changes during the developmental period and relies on tightly-regulated gene expression. Little is known regarding the complex expression patterns of mRNAs during the early stages of human liver development in comparison to post-natal livers. We used microarrays to detail the global programme of gene expression during liver development following specification, at the stage of proliferation and differentiation when compared to post-natal livers, and identified distinct classes of up-regulated and downregulated genes during this process.

(Submitter supplied) A deletion mutation in the growth hormone receptor (GHR) gene results in the inhibition of skeletal muscle growth and fat deposition in dwarf chickens. In this study, microarray techniques were used to detect the miRNA and mRNA expression profiles of 14-day-old embryo and 7-week-old chicken skeletal muscle of deletion-type dwarf chickens and normal-type chickens. Skeletal muscle tissues of Dwarf recessive White Rock chickens and normal recessive White Rock chickens were used to make the microarray assay. more...

(Submitter supplied) MicroRNAs (miRNAs) are non-coding RNAs that play a fundamental role in regulation of gene expression affecting differentiation and development. In particular, miRNAs have been described to regulate genes important for pancreatic development and islet function. The aim of this study was to determine the miRNA expression signature during human pancreas development. We identified 212 miRNAs that were expressed throughout different gestational ages. more...

(Submitter supplied) We investigated the miRNA expression in ex vivo human erythroid cultures from K562 cells. Hypothetically, the decline of certain miRNAs may promote erythropoiesis by unblocking expression of key functional proteins while the up-regulation of other miRNAs may block commitment to non-erythroid lineages. By comparison with the miRNA expression changes in human umbilical cord blood-derived CD34 cells, signature miRNAs for erythroid development can be discovered. more...

(Submitter supplied) We investigated the miRNA expression in ex vivo human erythroid cultures from umbilical cord blood (UCB)-derived CD34 cells. Hypothetically, the decline of certain miRNAs may promote erythropoiesis by unblocking expression of key functional proteins while the up-regulation of other miRNAs may block commitment to non-erythroid lineages. Therefore, discovering the patterns and sequence of miRNA expression during hematopoietic differentiation will provide insights about the functional roles of these tiny noncoding genes. more...

(Submitter supplied) We extracted total RNA from CD4+ T cells from 3 patient groups: chronic HIV-1 patients (CHI), long term non-progressors (LTNPs) and healthy controls (HC). Array results show that a large number of miRNAs are altered in HIV-1 infected patients compared to HC. Most of the differentially expressed miRNAs are down-regulated but there are some up-regulated miRNAs. A particular family of miRNAs which appear to be downregulated in HIV-1 infected patients is the let-7 family of miRNAs.
