Description
We investigated whether in vitro expansion of human alveolar epithelial type II cells is possible. We found that human endogenous human alveolar epithelial type II cells can be cultured and passaged. The culture system enabled retroviral gene transduction into human alveolar epithelial type II cells. We performed RNA sequencing of human alveolar epithelial type II cells transduced with mutant surfactant protein C or control vector. Overall design: Cultured human alveolar epithelial type II cells were transfected with retroviral vector containing mutant surfactant protein C or control retroviral vector. The retroviral vector contained LNGFR as a marker. After gene transduction, transduced cells were purified by magnetic-activated cell sorting. The transcriptome of the cells was generated by 5'Tag-seq using Ion Genestudio S5 Sequencer.

Description
In the alveoli, lung fibroblasts are in close contact with alveolar epithelial cells type 2, and are considered to support alveolar epithelial cells, forming an alveolar stem cell niche. However, what fibroblast-to-epithelial cell interactions occur during the alveolar maturation stage remains unclear. To understand the lung fibroblast-to-epithelial cell interactions, we performed time-course 3´SAGE-seq analysis of lung epithelial cells and fibroblasts. Overall design: Lung epithelial cells and lung fibroblasts from various developmental stages (E18.5, P0.5, P2, P7, P28, and P56) were purified by cell sorting. The time series transcriptome of the epithelial cells and fibroblasts was generated by 3'SAGE-seq using Ion Proton sequencer.

Description
Intratracheal transfer of isolated lung fibroblasts in bleomycin-induced lung fibrosis recapitulates the activation process of lung fibroblasts after epithelial injury. In order to investigate gene expression signatures of transferred fibroblasts, we purified transferred fibroblasts 2, 4, and 7 days after the transfer and performed transcriptome analysis. We also isolated Acta2 high and low cells by using Acta2-mKO1 reporter mice 4 days after the transfer. Overall design: Lung fibroblasts were isolated from untreated Col-GFP mice after tissue dissociation and negative selection for lineage markers. Isolated lung fibroblasts were intratracheally transferred into wild type mice, which received intratracheal bleomycin treatment 7 days before the transfer. Col-GFP+ cells were purified from the host lungs by FACS sorting on 2, 4, and 7 days after the transfer. Acta2 high and low cells were prepared by transferring lung fibroblasts from Acta2-mKO1 reporter mice. mRNA was isolated from sorted cells, and gene expression profiles were acquired by next generation sequencing.

Description
Quantitative phosphoproteome and transcriptome analysis of ligand-stimulated MCF-7 human breast cancer cells was performed to understand the mechanisms of tamoxifen resistance at a systems level. Phosphoproteome data revealed that wild type (WT) cells were more enriched with phospho-proteins than tamoxifen-resistant (TamR) cells after stimulation with ligands. Surprisingly, decreased phosphorylation after ligand perturbation was more common than increased phosphorylation. In particular, 17beta-estradiol (E2) induced down-regulation in WT cells at a very high rate. E2 and the ErbB ligand, heregulin (HRG) induced almost equal numbers of up-regulated phospho-proteins in WT cells. Pathway and motif activity analyses using transcriptome data additionally suggested that deregulated activation of GSK3B(glycogen synthase kinase 3 beta) and MAPK1/3 signaling might be associated with altered activation of CREB and AP-1 transcription factors in TamR cells and this hypothesis was validated by reporter assays. An examination of clinical samples revealed that, inhibitory phosphorylation of GSK3B at serine 9 was significantly lower in tamoxifen-treated breast cancer patients that eventually had relapses, implying that activation of GSK3B may be associated with the tamoxifen resistant phenotype. Thus, the combined phosphoproteome and transcriptome dataset analyses revealed distinct signal-transcription programs in tumor cells and provided a novel molecular target to understand tamoxifen resistance.
