Umkirch-1/Umkirch-3 hybrid plants and their parents were grown at 23SD and then shifted to 16SD for five days. 10 plants were pooled in each of three sample replicates.

View SamplesThere is increasing interest in using primary nasal epithelial cells (PNECs) instead of primary bronchial epithelial cells (PBECs) in order to study epithelial responses in rhinitis and asthma. This study aimed to establish a robust cell culture model appropriate for studying rhinovirus infection and the consequent epithelial responses in asthma and rhinitis. First, a comprehensive comparison of fresh and cryopreserved primary nasal epithelial cells from three donors before and after RV infection was conducted, using high throughput RNA sequencing and transcriptomics.

View SamplesGenomic instability promotes evolution and heterogeneity of tumors. Unraveling its mechanistic basis is essential to design appropriate therapeutic strategies. In a recent study we reported an unexpected oncogenic property of p21WAF1/Cip1 showing that its chronic expression, in a p53-deficient environment, causes genomic instability by deregulating the replication licensing machinery.

View SamplesPowdery mildew, caused by the fungus Blumeria graminis (DC) Speer, is one of the most important foliar diseases of cereals worldwide. It is an obligate biotrophic parasite, colonising leaf epidermal cells to obtain nutrients from the plant cells without killing them. Syringolin A (sylA), a circular peptide secreted by the phytopathogenic bacterium Pseudomonas syringae pv. syringae, triggers a hypersensitive cell death reaction (HR) at infection sites when sprayed onto powdery mildew infected wheat which essentially eradicates the fungus. The rational was to identify genes whose expression was specifically regulated during HR, i.e. genes that might be involved in the switch of compatibility to incompatibility.<br></br>Powdery mildew-infected or uninfected plants were treated with syringolin two days after infection and plant material for RNA extraction was collected at 0.5, 1, 2, 4, 8, 12 hours after treatment (hat), resulting in an early (2 and 4 hat) and late pool (8 and 12 hat). Plant material that was uninfected prior to syringolin treatment was collected 8 and 12 hat (late pool of uninfected plant material), and 1 hat, respectively.

View SamplesDNA Topoisomerase I (Top1) relaxes DNA supercoiling and is inhibited with high specificity by camptothecin, a natural product of chinese tree Camptotheca acuminata with anticancer activity. Topoisomerase activity is required at transcribing regions to modulate DNA supercoils generated by RNA polymerases. However, Top1 functions at promoters and molecular responses to CPT are not fully understood. We found that camptothecin increases antisense RNA polymerase II transcripts at active divergent CpG-island promoters in a replication-independent manner. Kinetics investigations of the formation of Top1-DNA cleavage complexes and non-B DNA structures showed that CPT interferes with Top1 modulation of negative DNA supercoiling at promoters. The present findings will be a resource to establish the role of such antisense RNAs in transcription regulation and to discover additional components of the response pathway. Moreover, the transcriptional camptothecin effects can be the molecular basis of the therapeutic activity in cancer as well as neurological syndromes.
