Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
The aim of the study was to elucidate the cellular origin of ameloblastoma and keratocystic odontogenic tumour, neoplasms believed to arise from dental epithelial cells, by carrying out a genome-wide expression analysis.
Publication Title
Early dental epithelial transcription factors distinguish ameloblastoma from keratocystic odontogenic tumor.

Description
Using PAXgene tubes, peripheral blood samples were collected from seven patients >18 years with documented pdm(H1N1) influenza, bilateral chest infiltrates, and in need of ventilation support. Significant co-morbidity was exclusion criterion. Expression profiles were compared with 7 age matched controls. Using a false discovery rate < 5% and an absolute fold change > 2, 370 genes were differentially expressed in case and controls.

Description
In the current study, we have performed a gene expression analysis of well characterized and defined populations of human adipose-derived stem cells (hASCs) before and after in vitro induction of osteogenic and myogenic differentiation that allows identifying DNA methylation- regulated differentiation genes. We have also address the extent of the epigenetic programming of hASCs- derived differentiated cells by comparing the expression profiling of these cells with their somatic counterparts from primary tissues. Finally, we also compared the patterns of expression of hASCs (and their derivatives)

Description
DNA methylation is a key epigenetic regulator of mammalian embryogenesis and somatic cell differentiation. Using high-resolution genome-scale maps of methylation patterns, we show that the formation of myelin in the peripheral nervous system, proceeds with progressive DNA demethylation, which coincides with an upregulation of critical genes of the myelination process. More importantly, we found that, in addition to expression of DNA methyltransferases and demethylases, the levels of S-adenosylmethionine (SAMe), the principal biological methyl donor, could also play a critical role in regulating DNA methylation during myelination and in the pathogenesis of diabetic neuropathy. In summary, this study provides compelling evidence that SAMe levels need to be tightly controlled to prevent aberrant DNA methylation patterns, and together with recently published studies on the influence of SAMe on histone methylation in cancer and embryonic stem cell differentiation show that in diverse biological processes, the methylome, and consequently gene expression patterns, are critically dependent on levels of SAMe.

Description
Purpose: using RNA-seq as a screening tool to determine candidate genes of interest within a genetically defined neural subpopulation in the zebrafish embryonic spinal cord. Results: The early embryonic spinal cord displays patterns of spontaneous activity that generate the earliest motor behavior in the zebrafish. We show the behavior and the neural activity to be inhibited by environmental levels of light. Since at these young ages the fish is blind, and since restricted illumination patterns on the trunk of the fish can elicit a photo-response, we hypothesized that the photo-inhibition is an intrinsic property of the active central pattern generator network within the spinal cord. We FACS-isolated cells from this network as well as those from a panneuronal population and sequenced mRNAs. Through differential expression analysis we identified vertebrate ancient long opsin a as a candidate and then further validated its function in the circuit through knockdown and rescue experiments. Overall design: RNA sequencing of 2 FACS purified neural populations from zebrafish spinal cord.

A spinal opsin controls early neural activity and drives a behavioral light response.

Description
The adaptor protein Lnk is an important negative regulator of HSC homeostasis and self-renewal. This study aims to investigate the role of Lnk in HSC aging. Here we performed expression profiling of bone marrow CD150+CD48-LSK LT-HSCs from young and old WT and Lnk-/- mice. Results identify select Lnk-mediated pathways with potential involvement in HSC self-renewal and aging.
Publication Title
Lnk deficiency partially mitigates hematopoietic stem cell aging.
