View SamplesHuman fibroblasts at different population doublings were treated with low amounts of rotenone (mild stress) and compared to untreated fibroblasts. Two different cell lines were used (MRC-5, HFF). Illumina sequencing (HiSeq2000) was applied to generate 50bp single-end reads. Jena Centre for Systems Biology of Ageing - JenAge (www.jenage.de) Overall design: 60 samples: 3 biological replicates for each group: MRC-5 cells at 4 different population doublings (PD) with and without rotenone; HFF cells at 6 different population doublings with and without rotenone

View SamplesRNA-Seq analysis of Treg cell subsets isolated from lungs of Il10GFPFoxp3Thy1.1 mice. Thy1.1+ Treg cells were FACS-sorted into IL-10–IL-18R–, IL-10+IL-18R– and IL10–IL-18R+ populations on day 5 following intranasal infection with 0.5 LD50 PR8-OTI influenza virus. Overall design: mRNA profiles of each Thy1.1+ Treg cell population (IL-10–IL-18R–, IL-10+IL-18R– and IL10–IL-18R+) from lungs on day 5 following influenza infection from 5 infected mice, sorted into TRIzol LS reagent.

View SamplesThymic Treg cells, mature non-Treg CD4+ single positive thymocytes, peripheral (spleen) resting and activated Treg cells were sorted from Foxp3-gfp reporter (wid type, WT) mice or Foxp3 enhancer CNS3 knockout (KO, carrying the same GFP reporter) mice. Total RNA was extracted and used for RNA sequencing to assess gene expression profiles. Overall design: Two 6-8 week old littermates of male Foxp3-gfp and Foxp3?CNS3-gfp mice were used to sort Treg cells and conventional CD4+ T cells. Lymphocyte preparation and electronic sorting were performed at the same time. RNA extraction, SMART amplification, library preparation were conducted in parallel.

View SamplesMouse embryonic fibroblasts (MEFs) were generated from 13.5-day-old embryos obtained from heterozygous PKBa mice intercrosses (Yang et al., 2003). Briefly, after dissection of head and visceral organs for genotyping, embryos were minced and trypsinized for 30 min at 37C. Embryonic fibroblasts were then plated and maintained in Dulbeccos Modified Eagle Medium (DMEM) with 10% foetal calf serum (FCS) (Life Technologies), 100 units/ml of penicillin and 100 mg/ml of streptomycin at 37C in an atmosphere of 5% CO2. All experiments were performed with wild-type and PKBa-/- MEFs between 15-20 passages. To induce adipocyte differentiation, 2-day-postconfluent cells (day 0) were treated with DMEM supplemented with 10% FCS, 8 mg/ml biotin, 4 mg/ml pantothenate, 0.5 mM 3-isobutyl-1-methylxanthine, 1 mM dexamethasone and 10 mg/ml insulin (all from Sigma). Total RNA was extracted from cells using TRIzol (Invitrogen) according to the manufacturers instructions.

View SamplesLung cancers exhibit pronounced functional heterogeneity, confounding precision medicine. We studied how the cell-of-origin contributes to phenotypic heterogeneity following conditional expression of KrasG12D and loss of Lkb1 (Kras;Lkb1). Using progenitor cell type-restricted adenoviral-Cre to target cells expressing Surfactant Protein C (SPC) or club cell antigen 10 (CC10), we show that Ad5-CC10-Cre infected mice exhibit a shorter latency compared with Ad5-SPC-Cre cohorts. We further demonstrate that CC10+ cells are the predominant progenitors of adenosquamous carcinoma (ASC) tumors, and give rise to a wider spectrum of histotypes that includes mucinous and acinar adenocarcinomas. Transcriptome analysis shows ASC histotype-specific upregulation of proinflammatory and immunomodulatory genes. This is accompanied with an ASC-specific immunosuppressive environment, consisting of downregulated MHC genes, recruitment of CD11b+ Gr-1+ tumor-associated neutrophils (TANs) and decreased T-cell numbers. We conclude that progenitor cell-specific etiology influences the Kras;Lkb1-driven tumor histopathology spectrum and histotype-specific immune microenvironment.
