Description
Liver X Receptors (LXRa and ß) are ligand-activated transcription factors that play a key role in the control of lipid homeostasis, as well as modulation of immunity and inflammation. LXR activity can be regulated by posttranslational modifications, such as phosphorylation. This study aims to assess changes in the hepatic transcriptional profiles of mice that carry a whole-body phosphorylation deficient knock in mutant of LXRa (S196A) compared to wild-type (WT) upon being fed a HFHC diet. Overall design: Liver mRNA profiles of either wild-type (WT) or LXRa-S196A female mice after being fed a High Fat-High Cholesterol diet for 6 weeks. Three biological replicate samples for each group are included. WT samples are used as controls.

Description
Regeneration of lung epithelium is vital for maintaining airway function and integrity. An imbalance between epithelial damage and repair is at the basis of numerous chronic lung diseases such as asthma, COPD, pulmonary fibrosis and lung cancer. IGF (Insulin-like Growth Factors) signaling has been associated with most of these respiratory pathologies, although their mechanisms of action in this tissue remain poorly understood. Expression profiles analyses of IGF system genes performed in mouse lung support their functional implication in pulmonary ontogeny. Immuno-localization revealed high expression levels of Igf1r (Insulin-like Growth Factor 1 Receptor) in lung epithelial cells, alveolar macrophages and smooth muscle. To further understand the role of Igf1r in pulmonary homeostasis, two distinct lung epithelial-specific Igf1r mutant mice were generated and studied. The lack of Igf1r disturbed airway epithelial differentiation in adult mice revealed enhanced proliferation and altered morphology in distal airway club cells. During recovery after naphthalene-induced club cell injury, the kinetics of terminal bronchiolar epithelium regeneration was hindered in Igf1r mutants, revealing increased proliferation and delayed differentiation of club and ciliated cells. Amid airway restoration, lungs of Igf1r deficient mice showed increased levels of Igf1, Insr, Igfbp3 and epithelial precursor markers, reduced amounts of Scgb1a1 protein, and alterations in IGF signaling mediators. These results support the role of Igf1r in controlling the kinetics of cell proliferation and differentiation during pulmonary airway epithelial regeneration after injury. Overall design: Lung mRNA profiles of 3 months-old Igf1rfl/fl normal/control transgenic mice were generated by deep sequencing using Illumina GAIIx. ------------------------------------------- Submitter states "we use data on the absolute transcription levels (FPKM) of same IGF system genes on the adult "normal" mouse lung to compare them with those reported in the human adult lung (expressed in both as FPKM) (http://www.proteinatlas.org/)".

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.

Description
Different mutations in the gene encoding humans IGF-I cause intrauterine growth retardation, postnatal growth failure, microcephaly, mental retardation, bilateral sensorineural deafness and multiple dysmorphic features. Insight into the role of IGFs in inner ear cochlear ganglion neurogenesis has come from the study of genetically modified mice. Postnatal cochlear development is severely impaired in mice Igf1-/-, which develop smaller cochlea and cochlear ganglia, an immature tectorial membrane and they display a significant decrease in the number and size of auditory neurons.

Description
We identified a novel homozygous 15q13.3 microdeletion in a young boy with a complex neurodevelopmental disorder characterized by severe cerebral visual impairment with additional signs of congenital stationary night blindness (CSNB), congenital hypotonia with areflexia, profound intellectual disability, and refractory epilepsy. The mechanisms by which the genes in the deleted region exert their effect are unclear. In this paper we probed the role of downstream effects of the deletions as a contributing mechanism to the molecular basis of the observed phenotype. We analyzed gene expression of lymphoblastoid cells derived from peripheral blood of the proband and his relatives to ascertain the relative effects of the homozygous and heterozygous deletions.

The goal of the study was to compare transcriptome changes in HeLa cells after infection with recombinant Thogoto virus (wild-type, ML deletioin mutant or ML SW mutant not able to interact wiith TFIIB. While wild-type virus is able to inhibit inflammatory genes, ML deletion mutant and TFIIB-non-interacting mutant lose this effect on gene transcription. Overall design: Examination of transcriptome changes in HeLa cells under steady state or after THOV infection using Illumina HiSeq.
