Affymetrix Barley Genome Array (barley1)
Description
The photosynthetic organs of the barley spike (lemma, palea and awn) are resistant to drought. This is a beneficial trait because they can sustain grain-filling when drought occurs at the reproductive stage. There is little information about gene expression in the spike organs under drought conditions. In this study, we compared gene expression in drought-stressed lemma, palea, awn and seed at the grain-filling stage using the Barley1 Genome Array in order to identify drought-regulated organ-specific genes.

- Affymetrix Barley Genome Array (barley1)
Description
The lemma, the palea and the awn of a barley spike are photosynthetic organs and supply the developing seed with carbohydrates. In addition, the lemma and the palea cover the seed and protect it from pathogens and insects. In this study, we compared gene expression among the lemma, the palea, the awn and the developing seed of barley at the grain-filling stage (Zadok scale 83) using the Barley1 Genome Array in order to identify genes that determine the primary function of these organs.

Description
Atrial fibrillation (AF) is currently the most prevalent arrhythmia worldwide.Recent clinical data implicate the additional contribution of non-coding RNAs in the pathogenesis of AFwhich include microRNAs(miRNAs), endogenous small interfering RNAs, PIWIinteracting RNAs, and lncRNA. Notably, a growing number of lncRNAs have been implicated in disease etiology, although an association with AF has not been reported.

Description
We extracted nascent plasma cell tumor (PCT) cells from within inflammatory granulomas (OG) isolated from intraperitoneal pristane-injected BALB/c.iMyc E mice at five different time points during tumor progression. We used laser capture micro-dissection to collect incipient PCT cells and analyzed their global gene expression on Affymetrix Mouse Genome 430A microarrays. Two independent studies were performed with different sets of mice

Description
The objective of the overall study was to determine the effects of oral vitamin D supplementation on alveolar macrophages from human subjects. In this substudy, subjects treated with vitamin D (intervention group) in paired analysis had small, but significant effects on immune-related differential gene expression pre versus post supplementation.

Description
There is a critical need in cancer therapeutics to identify targeted therapies that will improve outcomes and decrease toxicities compared to conventional, cytotoxic chemotherapy. Ewing sarcoma is a highly aggressive bone and soft tissue cancer that is caused by the EWS-FLI1 fusion protein. Although EWS-FLI1 is specific for cancer cells, and required for tumorigenesis, directly targeting this transcription factor has proven challenging. Consequently, targeting unique dependencies or key downstream mediators of EWS-FLI1 represent important alternative strategies. We used gene expression data derived from a genetically defined model of Ewing sarcoma to interrogate the Connectivity Map and identify a class of drugs, iron chelators, that downregulate a significant number of EWS-FLI1 target genes. We then identified ribonucleotide reductase M2 (RRM2), the iron-dependent subunit of ribonucleotide reductase (RNR), as one mediator of iron chelator toxicity in Ewing sarcoma cells. Inhibition of RNR in Ewing sarcoma cells led to apoptosis and cell death in vitro and attenuated tumor growth in vivo in a xenograft model. Additionally, we discovered that the sensitivity of Ewing sarcoma cells to inhibition or suppression of RNR is mediated, in part, by high levels of SLFN11, a protein that sensitizes cells to DNA damage. This work demonstrates a unique dependency of Ewing sarcoma cells on RNR and supports further exploration of clinically used inhibitors of RNR as a therapeutic approach in treating this cancer.
