Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
The gastrointestinal tract of mammals is inhabited by hundreds of distinct species of commensal microorganisms that exist in a mutualistic relationship with the host. The process by which the commensal microbiota influence the host immune system is poorly understood. We show here that colonization of the small intestine of mice with a single commensal microbe, segmented filamentous bacterium (SFB), is sufficient to induce the appearance of CD4+ T helper cells that produce IL-17 and IL-22 (Th17 cells) in the lamina propria. SFB adhere tightly to the surface of epithelial cells in the terminal ileum of mice with Th17 cells but are absent from mice that have few Th17 cells. Colonization with SFB was correlated with increased expression of genes associated with inflammation, anti-microbial defenses, and tissue repair, and resulted in enhanced resistance to the intestinal pathogen Citrobacter rodentium. Control of Th17 cell differentiation by SFB may thus establish a balance between optimal host defense preparedness and potentially damaging T cell responses. Manipulation of this commensal-regulated pathway may provide new opportunities for enhancing mucosal immunity and treating autoimmune disease.

Description
Here, we report the generation of human induced Pluripotent Stem (iPS) cell reporter line in which a venus fluorescent protein have been introduced into the PAX7 locus. We use microarrays to compare the transcriptome of PAX7-venus+ cells after 3 weeks of myogenic differentiation to that of undifferentiated iPS

Illumina HiSeq 1500
Description
We report that Klebsiella pneumoniae promote Th1 cell induction in colon. To examine the influence of Klebsiella on colonic epithelial cells (ECs) and lamina propria CD11c+ dendritic cells (DCs), we performed RNA seq on them. Germ free mice were orally inoculated with Kp-2H7 or BAA-2552 and total RNA was isolated from colonic ECs and DCs 1 week after inoculation. Furthermore, we examined the involvement of TLRs in induction of Th1 cells using Myd88 KO, Trif KO, Myd88/Trif DKO mice. These deficient germ free mice were orally inoculated with Kp-2H7 and total RNA was isolated from colonic ECs 3 weeks after inoculation. Overall design: The gene expression of colonic ECs and DCs isolated from germ free mice, and GF mice inoculated with Kp-2H7 or BAA-2552, and colonic ECs isolated from GF Myd88 KO, Trif KO or Myd88/Trif DKO mice inoculated with Kp-2H7.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Fibroadenomas are the most common benign breast tumors in women under 30. Unlike their malignant counterparts, relatively molecular profiling has been done on fibroadenomas. Here we performed gene expression profiling on ten fibroadenomas in order to better characterize these tumors. Through targeted amplicon sequencing, we have found that six of these tumors have MED12 mutations. We show that the MED12 mutations, among others, are associated with activated estrogen signaling, as well as increased invasiveness through upregulation of ECM remodelling genes.
