Description
Erythroid progenitor BFU-Es are so-named based on their ability to generate in methylcellulose culture large colonies of erythroid cells that consist of “bursts” of smaller erythroid colonies derived from the later CFU-E Epo- dependent progenitors. “Early” BFU-E cells forming large BFU-E colonies presumably have higher capacities for self-renewal than do those forming small BFU-E colonies. In order to understand the mechanism underlying this heterogeneity, we conducted single cell transcriptome analysis on BFU-E cells purified from mouse embryos. Our analyses showed that there are two principal subgroups of mouse BFU-E cells and that the type III TGFß receptor (TßRIII) is a potential marker that distinguishes “early” and “late” BFU-Es. Expression of TßRIII is correlated with that of GATA1, a gene encoding an erythroid transcription factor induced during the BFU-E to CFU-E transition. The mouse and human BFU-E sub populations (TßRIII10%lo) expressing the 10% lowest amount of surface TßRIII are indeed enriched for early BFU-Es, and are significantly more responsive to glucocorticoid stimulation, which promotes BFU-E self-renewal, as compared to the total BFU-E population. The TßRIII10%lo BFU-E subpopulation presumably represents earlier BFU-Es with maximal capacity for self-renewal. Consistent with this notion, signaling by the TGFß receptor kinases RI and RII increases during the transition from early (TßRIII10%lo) to late (TßRIII10%hi) BFU-Es and then decreases in CFU-E cells. Blocking TGF-ß signaling by receptor kinase inhibitors increase TßRIII10%lo BFU-E cell self-renewal and increases total erythroblast production, suggesting the use of this type of drug in treating Epo unresponsive anemias. Overall design: Discovery of BFU-E subpopulations

Description
The regulatory mechanisms that shapes the hepatic zonation is not well understood. In addition, the concept and significance of of hepatic zonation is well established in rodens, however, its relavence to human liver biology remain elusive. We conducted a comprehensive transcriptome analysis of each zonation within normal human liver vis Laser Capture Microdissection approach. Here, we report a poly A RNA sequencing data of the individual zone of liver tissue as well as the whole liver of the corresponding subjects. Overall design: The RNA samples were collected from each zone within hepatic lobule by a Laser Captured Microdissection approach. This study examined the gene expression profile in each zone of the normal human liver.

Description
Pro-opiomelanocortin (POMC)- and agouti-related peptide (AgRP)-expressing neurons of the arcuate nucleus of the hypothalamus (ARC) are oppositely regulated by caloric depletion and coordinately stimulate and inhibit homeostatic satiety, respectively. This bimodality is principally underscored by the antagonistic actions of these ligands at downstream melanocortin-4 receptors (MC4R) in the paraventricular nucleus of the hypothalamus (PVH). Although this population is critical to energy balance, the underlying neural circuitry remains unknown. Using mice expressing Cre recombinase in MC4R neurons, we demonstrate bidirectional control of feeding following real-time activation and inhibition of PVH(MC4R) neurons and further identify these cells as a functional exponent of ARC(AgRP) neuron-driven hunger. Moreover, we reveal this function to be mediated by a PVH(MC4R)?lateral parabrachial nucleus (LPBN) pathway. Activation of this circuit encodes positive valence, but only in calorically depleted mice. Thus, the satiating and appetitive nature of PVH(MC4R)?LPBN neurons supports the principles of drive reduction and highlights this circuit as a promising target for antiobesity drug development. Overall design: Single-neuron mRNA-seq was performed on fluorescently-labeled or -unlabeled cells that were manually isolated from dissociated adult mouse paraventricular and arcuate hypothalamus: Mc4r-2a-Cre::L10-GFP+ or Mc4r-2a-Cre::AAV-XFP+ or Mc4r-2a-Cre::AAV-XFP-negative PVH neurons; Agrp-IRES-Cre::L10-GFP+ ARC neurons; Pomc-hrGFP+ ARC neurons; and vGLUT2-IRES-Cre::AAV-XFP+ ARC neurons Note: Raw files unavailable for samples GSM2413312 GSM2413313 GSM2413314 GSM2413346 GSM2413347

Description
This study addresses long-term effects of clinically relevant regimens of radiation in human glioma stem cells. Our investigations reveal a strikingly diverse spectrum of changes in cell behavior, gene expression patterns and tumor-propagating capacities evoked by radiation in different types of glioma stem cells. Evidence is provided that degree of cellular plasticity but not the propensity to self-renew is an important factor influencing radiation-induced changes in the tumor-propagating capacity of glioma stem cells. Gene expression analyses indicate that paralell transcriptomic responses to radiation underlie similarity of clinically relevant cellular outcomes such as the ability to promote tumor growth after radiation. Our findings underscore the importance of longitudinal characterizations of molecular and cellular responses evoked by cytotoxic treatrments in glioma stem cells.
