Affymetrix Mouse Gene 2.0 ST Array (mogene20st)
Description
Fzd2 is a Wnt receptor expressed in the embryonic lung. We made a conditional knockout of Fzd2 to specifically address the role of signaling through Fzd2 in lung epithelial development.

Description
Ezh2 epigenetically suppresses developmentally-regulated genes. Ezh2 is highly expressed during development, including in the lung. We knocked out Ezh2 in the developing lung epithelium using a Shh-cre driver which is active in foregut endoderm prior to lung morphogenesis. Many developmentally regulated genes became derepressed in the mutant lungs, leading to defects in lung development.

Description
To identify potential biological functions for three lncRNAs (NANCI, LL12, and LL34) we used shRNAs to knockdown expression of lncRNAs in MLE12 cells, a cell resembling type two lung epithelial cells. This data set contains the microarrays looking at gene expression.

Description
The molecular mechanism of how lung sacculation occurs is poorly understood. Loss of epithelial Hdac3 results in defects in the proper expansion of distal lung saccules into primitive alveoli. In this microarray, we seek to investigate the gene profile changes caused by loss of Hdac3 to better understand the molecular pathways that are regulated by Hdac3 during lung sacculation.

Description
We used microarrays to measure the expression levels of genes in irradiated immortalized B cells, lymphoblastoid cells, from members of Centre d'Etude du Polymorphisme Humain (CEPH) Utah pedigrees. Data were collected for cells at baseline and 2 hour and 6 hour after exposure to 10 Gy of ionizing radiation (IR).

Description
The lung alveolus is the primary site of gas exchange in mammals. Within the alveolus, the alveolar type 2 (AT2) epithelial cell population generates surfactant to maintain alveolar structure and harbors a regenerative capacity to repair the alveolus after injury. We show that a Wnt-responsive alveolar epithelial progenitor (AEP) lineage within the AT2 cell population is critical for regenerating the alveolar niche. AEPs are a stable lineage during alveolar homeostasis but expand rapidly to regenerate a majority of the alveolar epithelium after acute lung injury. AEPs exhibit a distinct transcriptome, epigenome, and functional phenotype with specific responsiveness to Wnt and FGF signaling that modulates differentiation and self-renewal, respectively. Importantly, human AEPs (hAEPs) can be isolated and characterized through a conserved surface marker and are required for human alveolar self-renewal and differentiation using alveolar organoid assays. Together, our findings show that AEPs are an evolutionarily conserved alveolar progenitor lineage essential for regenerating the alveolar niche in the mammalian lung.

Description
We have utilized the RNA-Seq technology to identify genes with distinct expression patterns between failing and non-failing hearts. In an era of next-generation sequencing studies, our study demonstrates how knowledge gained from a small set of samples with accurately measured gene expressions using RNA-Seq can be leveraged as a complementary strategy to discern the genetics of complex disorders.
