Description
We report the impact of side-stream cigarette smoking on baseline tracriptional status of enriched epithelium from the distal lung of both male and female control mice or mice harboring a mutation in the nicotinc alpha7 recptor that selectivley diminshes the calcium current (E260A). Overall design: Mice (male or female) of each nicotinic recptor alpha7 genotype (Control (c) or mutant (E260A)) were exposed to side-stream cigarette smoke 5 days per week for four months. The distal lung epithelium was enriched and poly-adenylated strand-specific RNA-Seq libraries using Illumina TruSeq stranded mRNA were preared for analysis.

Description
Constitutive low level DNA damage in RNASEH2 deficiency is linked to innate immune activation. Hierarchical clustering of over 16000 transcripts revealed remarkably similar profiles in patients with lupus erythematosus and patients with AGS with up-regulation of genes involved in DNA damage signaling and type I-IFN signaling. Overall design: Comparison of transcriptional profiles of native RNASEH2-deficient patient fibroblasts with wild type cells.

Description
Two-dimensional (2D) nanomaterials, an ultrathin class of materials such as graphene, nanoclays, transition metal dichalcogenides (TMDs), and transition metal oxides (TMOs), have emerged as a new generation of materials due to their unique properties relative to macroscale counterparts. However, little is known about the transcriptome dynamics following exposure to these nanomaterials. Here we investigate the interactions of 2D nanosilicates, a layered clay, with human mesenchymal stem cells (hMSCs) at the whole transcriptome level by high-throughput sequencing (RNA-seq). Analysis of cell-nanosilicate interactions by monitoring change in transcriptome profile uncovers key biophysical and biochemical cellular pathways triggered by nanosilicates. A widespread alteration of genes is observed due to nanosilicate exposure as more than 4,000 genes are differentially expressed. The change in mRNA expression levels reveal clathrin-mediated endocytosis of nanosilicates. Nanosilicate attachment to cell membrane and subsequent cellular internalization activate stress-responsive pathways such as mitogen activated protein kinase (MAPK), which subsequently directs hMSC differentiation towards osteogenic and chondrogenic lineages. This study provides transcriptomic insight on the role of surface-mediated cellular signaling triggered by nanomaterials and enables development of nanomaterials-based therapeutics for regenerative medicine. This approach in understanding nanomaterial-cell interactions, illustrates how change in transcriptomic profile can predict downstream effects following nanomaterial treatment. Overall design: Examination of affect of 2D nanosilicates on hMSCs

Description
P3 Math1-nGFP mouse cochlear sensory epithelia, consisting of greater and lesser epithelial ridges (GER & LER) including the organ of Corti with nGFP-positive hair cells, were dissected, dissociated into single cells, and labeled with propidium iodide and three CD marker antibodies. The cell suspension was subjected to FACS purification. 83.6 2.8% of the total input of cells were viable, determined by exclusion of propidium iodide. Only viable cells were collected into 5 distinct populations: GFP+ cells (Samples HC_A-D), GFP/CD271High (Samples Mac_A-C), as well as GFP/CD271Low/CD326+/CD146Low (Samples SC_A-B), GFP/CD271Low/CD326+/CD146Hig (Samples GER_A-B), and GFP/CD271Low/CD326 (Sample BM_B).
