Project description:We compared gene expression in T1alpha (-/-) lungs vs wild type at dpc 18.5 when the phenotype is moderate and at term when the phenotype is more severe. Lungs present narrow and irregular alveolar spaces, thicker mesenchyme, reduced number of attenuated type I cells, normal numbers of type II cells and secreted surfactant. At term, but not a dpc 18.5, there is increased proliferation of distal cells. We compared gene expression of T1alpha null mutant lungs to wild type lungs at dpc 18.5. The mutant phenotype at this developmental stage is moderate but the alveolar sacs are narrower than normal. Keywords: other

Project description:Despite the fact that we are constantly exposed to various environmental compounds, very few studies explore the impact of combined exposure to physical and chemical pollutants on reproductive health. Until now, assessment of pollutants is mostly based on the evaluation of single pollutant or combination of chemicals with common features and modes of action. In this context, numerous studies have demonstrated that steroidogenesis and gametogenesis, the main testicular functions, are well-known to be sensitize by endocrine disruptors (as Bisphenol A) and DNA-damaging agents (as γ-rays) respectively. In this study, we aim to investigate short and long term testicular transcriptionnal alterations of combined fetal exposure to well-known environmental toxicants: γ-rays (RAD) and BPA. To discriminate specific signatures of BPA or RAD exposure after combined exposure and evidence the type of synergisms between this pollutants, we performed transcriptomic analyses on testis exposed to BPA or RAD alone and co-exposed with BPA and RAD and compared gene expression with control condition. For this, we exposed pregnant mice from 10.5 dpc to 18.5 dpc to 10µM of BPA (in drinking water) and/or we irradiated mice at 12.5 dpc to 0.2 Gy. We performed transcriptomic analyses on fetal testis (18.5 dpc) and adult testis (3 months) to evaluate short and long term cell response after in utero exposure.

Project description:Insight into the role of Insulin-like Growth Factor (IGF) in development of lungs has come from the study of genetically modified mice. IGF1 is a key factor during lung development. IGF1 deficiency in the neonatal mouse causes respiratory failure collapsed alveoli and altered alveolar septa. To further characterize IGF1 function during lung development we analyzed Igf1-/- mouse prenatal lungs in a C57Bl/6 genetic background. Mutant lungs showed disproportional hypoplasia, disorganized extracellular matrix and dilated alveolar capillaries. IGF1 target genes during lung maturation were identified by analyzing RNA differential expression in Igf1-/- lungs using microarrays. Lungs from E18.5 were isolated from both Igf1+/+ wild type and Igf1-/- null mice and pooled to obtain RNA. Heterozygous male and female with a genetic background C57BL/6J were mated to obtain embryos at embrionic (E) stage 18.5 days post coitum (E18.5). 3 biological replicates per genotype.
