Description
Non-steroidal anti-inflammatory drugs (NSAIDs) are used extensively as therapeutic agents, despite their well-documented gastrointestinal (GI) toxicity. Presently, the mechanisms responsible for NSAID-associated GI damage are incompletely understood. In this study, we used Microarray analysis to generate a novel hypothesis about cellular mechanisms that underlie the GI toxicity of NSAIDs. Monolayers of intestinal epithelial

Description
The alveolar type 1 (AT1) cell covers >95% of the gas exchange surface and is extremely thin to facilitate passive gas diffusion. The development of this highly specialized cell is poorly understood including fundamental questions regarding cell number and morphology. Using new molecular stereology and single cell imaging methods, we show that AT1 cells develop via a non-proliferative two-step process while maintaining proliferative potential. In the flattening step, AT1 cells remodel cell junctions and undergo molecular specification. In the folding step, AT1 cells are sculptured to match secondary septa formation, resulting in a single AT1 cell spanning multiple alveoli. AT1 cells grow in size by >10-fold, fueling most of the postnatal lung growth. Strikingly AT1 cells proliferate upon ectopic SOX2 expression and undergo stage-dependent cell fate reprogramming. These results contradict the traditional view of AT1 cells being terminally differentiated and provide insights to alveolar maturation. In this experiment, we conducted next-generation sequencing on flow-sorter AT1 cells isolated from mouse lungs ectopically expressing Sox2 under the control of the AT1-specific promoter Scnn1a versus control AT1 cells. Overall design: Two samples of Sox2-expressing AT1 cells versus two control AT1 samples.

Description
In depth temporal profiling of transcript changes at 10 time points during germination in Arabidopsis seed was carried out. The time course utilised, encompassed seed maturation, stratification, germination and post-germination and provided a global investigation into the tightly regulated, phasic changes that define seed germination.

Description
The antagonistic interaction between iron (Fe) and phosphorus (P) has been noted in the area of plant nutrition. To understand the physiology and molecular mechanisms of this interaction, we studied the growth performance, nutrient concentration, and gene expression profiles of root and shoot segments derived from 10-d-old rice (Oryza sativa) seedlings under four different nutrient conditions: (1) full strength of Fe and P (+Fe+P); (2) full strength of P and no Fe (-Fe+P); (3) full strength of Fe and no P (+Fe-P); and (4) without both Fe and P (-Fe-P).

Description
Arabidopsis ABA hpersensitive germination2-1 mutant shows an enhanced sensitivity to ABA. This mutant has higher levels of endogenous ABA. This mutant also exhibited SA hypersensitivity and dwarf phenotype. Regarding SA hypersensitivity, ahg2-1 exhibits higher endogenous SA level and an enhanced resistance to pathogenic bacteria. Since AHG2 encodes the Arabidopsis polyA specific ribonuclease that is involved in mRNA degradation, presumably abnormal accumulation of some mRNAs confers the unique phenotype. Transcriptome analyses are expected to offer information on the target of AHG2. In order to eliminate secondary effects of higher levels of ABA and SA, ahg2-1abi1-1 and ahg2-1sid2-2 double mutants were also examined. The transcriptome data revealed that; ahg2-1 confers unique gene expression profiles, ABA and SA affect the expression profiles of this mutant but many genes are independent of those plant hormone responses. Comparing with expression profiles of other mutants indicated that the ahg2-1 might affect mitochondrial function.
