Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Analysis of lung samples from mice infected with a severe H5N1 influenza virus (VN/1203/04/H5N1) or a mild H1N1 influenza virus (NYMC-X-179A) on day 3 and day 5 post-infection. Uninfected controls were used for comparison.

Description
The first site exhibiting hematopoietic activity in mammalian development is the yolk sac blood island, which originates from the hemangioblast. Here we performed differentiation assays, as well as genome-wide molecular and functional studies in BL-CFCs to gain insight into the function of the essential Ldb1 factor in early primitive hematopoietic development. We show that the previously reported lack of yolk sac hematopoiesis and vascular development in Ldb1-/- mouse result from a decreased number of hemangioblasts and a block in their ability to differentiate into erythroid and endothelial progenitor cells. Transcriptome analysis and correlation with the genome wide binding pattern of Ldb1 in hemangioblasts revealed a number of direct target genes and pathways misregulated in the absence of Ldb1. The regulation of essential developmental factors by Ldb1 defines it as an upstream transcriptional regulator of hematopoietic/endothelial development. We show the complex interplay that exists between transcription factors and signaling pathways during the very early stages of hematopoietic/endothelial development and the specific signalling occurring in hemangioblasts in contrast to more advanced hematopoietic developmental stages. Finally, by revealing novel genes and pathways, not previously associated with early development, our study provides novel candidate targets to manipulate the differentiation of hematopoietic and/or endothelial cells.

Description
Approximately 60-70% of patients with pulmonary sarcoidosis have a good outcome, with disease that resolves spontaneously. It is unclear why some patients progress to fibrotic disease, and there is currently no marker that differentiates these patients from those with self-limiting lung disease.
Publication Title
Gene set analysis of lung samples provides insight into pathogenesis of progressive, fibrotic pulmonary sarcoidosis.

Description
The involvment of bile acids such as deoxycholic acid (DCA) in gastro-esophageal reflux disease and subsequent Barretts metaplsia has been postulated. This study examines gene expression induced by exposure to DCA in esophageal cells and may be utilised in cross-comparisons with data derived from gene expression studies of Barretts esophagus and associated adenocarcinoma.

This study examines gene expression induced by exposure to DCA in esophageal cells and may be utilised in cross-comparisions with data derived from gene expression studies of Barretts esophagus and associated adenocarcinoma. Additionally this study may be used to assess divergence in response to bile acids by comparisons with similar study performed in SKGT4 barrett''s assocaited adenocarcinoma cell line.

Description
Mechanosensory hair cells (HCs) are the primary receptors of our senses of hearing and balance. However, very little is known about the transcriptional regulators involved in HC fate determination and differentiation. In this paper, we show that expression of three HC lineage-specific transcription factors: Gfi1, Pou4f3 and Atoh1, can induce a direct commitment towards HC fate during in vitro embryonic stem cell (ESC) differentiation. Induced HCs (iHCs) express numerous HC-specific genes and exhibit polarized membrane protusions reminiscent of stereociliary bundles.

Description
This study utilise the examination of normal gastro-intestinal tissues to determine a tissue specific signal for use in deriving the intestinal signature of intestinal metaplasias of the oesophagus. Normal oesophageal, colonic and duodenal tissue biopsies were taken after informed consent and RNA was extracted following histological examination of adjacent tissues for normal aperaing mucosa.
Publication Title
