Primary culture airway epithelial cells, grown under physiologic air-liquid interface conditions, with, or without IL-13 in order to study the effects of this cytokine on mucous cell metaplasia, an important feature of asthma and COPD.
IL-13-induced airway mucus production is attenuated by MAPK13 inhibition.

View SamplesIn birds and mammals, all mesoderm cells are generated from the primitive streak. Nascent mesoderm cells contain unique dorso-ventral (D/V) identities depending on their relative ingression position along the streak. Molecular mechanisms controlling this initial phase of mesoderm diversification are not well-understood. Using chick model, we generated high-quality transcriptomic datasets of different streak regions and analyzed their molecular heterogeneity.

View SamplesMice representing phenotypic extremes of airway hyperreactivity and goblet cell metaplasia post-Sendai virus infection were identified from a 500 mouse F2 cohort (CB6F2/J). Whole lung RNA from 3 mice at each extreme was analyzed via microarray for gene expression. Subsequent pairwise comparisons between arrays allowed the identification of genes differentially expressed with respect to the disease phenotypes (airway hyperreactivity and goblet cell metaplasia).

View SamplesIn zebrafish, parental exposure to ionizing radiation has been associated with effects in offspring, such as increased DNA damage and reactive oxygen species. Here, we assessed short (one month) and long term effects (one year) on gene expression in embryonic offspring (5.5 hours post fertilization) from zebrafish exposed during gametogenesis to gamma radiation (8.7 or 53 mGy/h for 27 days, total dose 5.2 or 31 Gy). One month after exposure, a global change in gene expression was observed in offspring from the 53 mGy/h group, followed by embryonic death at late gastrula, whereas offspring from the 8.7 mGy/h group was unaffected. One year after exposure, embryos from the 8.7 mGy/h group exhibited 2455(61.8% downregulated) differentially expressed genes. Overlaps in differentially expressed genes and enriched biological pathways were evident between the 53 mGy/h group one month and 8.7 mGy/h one year after exposure, which could be linked to effects in adults and offspring, such as DNA damage and lipid peroxidation. Interestingly, pathways between the two groups were oppositely regulated. Our results indicate latent effects following ionizing radiation exposure in parents that can be transmitted to offspring and warrants monitoring effects over subsequent generations. Overall design: One month after exposure, mRNA from F1 5.5 hpf embryos from parents exposed to 8.7 and 53 mGy/h gamma radiation during gametogenesis was sequenced on the Illumina 4000 platform with three replicas per treatment. One year after exposure, mRNA from F1 embryos from the same parents exposed to 8.7 mGy/h was sequenced with three biological replicates. In both cases, F1 embryos from non-exposed parents were used as control and mRNA sequenced in triplicates, taken at the same time points as the exposed samples.
Parental exposure to gamma radiation causes progressively altered transcriptomes linked to adverse effects in zebrafish offspring.

Progression from low- to high-grade in a glioblastoma model reveals the pivotal role of immunoediting.

View SamplesThe different phases of tumor immunoediting in vivo were dissected thanks to a murine model of glioma induced by PDGF-B overexpression. We show that low-grade gliomas are highly immunostimulatory and that the adaptive immune system prevents the development of secondary tumor in syngeneic mice. During tumor progression, glioma cells downregulate immunostimulatory genes and the immune infiltrate becomes pro-tumorigenic. We showed that glioma cells are able to progress towards a high-grade phenotype even in immunodeficient mice, albeit more slowly and this progression invariably requires a downregulation of immunostimulatory genes.
