Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Idiopathic pulmonary fibrosis (IPF) and non-specific interstitial pneumonia (NSIP) are the 2 most common forms of idiopathic interstitial pneumonia. Response to therapy and prognosis are remarkably different. The clinical-radiographic distinction between IPF and NSIP may be challenging. We sought to investigate the gene expression profile of IPF vs. NSIP
Publication Title
Comprehensive gene expression profiling identifies distinct and overlapping transcriptional profiles in non-specific interstitial pneumonia and idiopathic pulmonary fibrosis.

Description
Regulation of gene expression at the post-transcriptional level plays an indispensable role during TGFbeta-induced EMT and metastasis. This regulation involves a transcript-selective translational regulatory pathway in which a ribonucleoprotein (mRNP) complex, consisting of heterogeneous nuclear ribonucleoprotein E1 (hnRNP E1) and eukaryotic elongation factor 1A1 (eEF1A1), binds to a 3-UTR regulatory BAT (TGF activated translation) element and silences translation of Dab2 and ILEI mRNAs, two transcripts which are involved in mediating EMT. TGFbeta activates a kinase cascade terminating in the phosphorylation of hnRNP E1, by isoform-specific stimulation of protein kinase B/Akt2, inducing the release of the mRNP complex from the 3-UTR element, resulting in the reversal of translational silencing and increased expression of Dab2 and ILEI transcripts.

Description
HPV E6 from the genus alpha 'high risk' types such as HPV16 recruit the ubiquitin ligase E6AP to ubiquitinate p53 and target it for proteasome-mediated degradation. This results in the functional inactivation of p53 in HPV16-E6 expressing cells.

Description
Study the training exercise effects in chronic obstructive pulmonary disease (COPD) patients and aged-matched healthy individuals. Skeletal muscle biopsies from 9 stable COPD patients with normal fat free mass index (FFMI, 21Kg/m2) (COPDN), 6 COPD patients with low FFMI (16Kg/m2) (COPL), and 12 healthy sedentary subjects (FFMI 21Kg/m2) before and after 8 weeks of a supervised endurance exercise program were analyzed.
Publication Title
A systems biology approach identifies molecular networks defining skeletal muscle abnormalities in chronic obstructive pulmonary disease.

Description
Upon G1-S transition, cyclin-dependent kinases (CDKs) phosphorylate the retinoblastoma tumor suppressor protein (pRB) to release E2F transcription factors, which activate transcriptional programs, required for S-phase entry. Beyond the G1-S transition, pRB activity remains poorly understood. Our lab has discovered that pRB retains exclusive binding to E2F1 through an alternate E2F1-specific binding site at the pRB c-terminus independent of CDK phosphorylation. We have developed a gene-targeted mouse model that is defective for the E2F1-specific interaction. We are exploring the function of this complex through genome-wide binding and expression profiling. Overall, this work suggests an alternate pRB-E2F1 complex persists independent of CDK phosphorylation to establish regions of constitutive heterochromatin

Description
Upon G1-S transition, cyclin-dependent kinases (CDKs) phosphorylate the retinoblastoma tumor suppressor protein (pRB) to release E2F transcription factors, which activate transcriptional programs, required for S-phase entry. Beyond the G1-S transition, pRB activity remains poorly understood. Our lab has discovered that hyperphosphorylated pRB (ppRB), found beyond G1, retains exclusive binding to E2F1 through an alternate E2F1-‘specific’ binding site at the pRB c-terminus. We have developed a gene-targeted mouse model that is defective for the E2F1-‘specific’ interaction. We are exploring the function of this complex through genome-wide expression profiling. Overall, this work suggests an alternate pRB-E2F1 complex persists beyond the G1-S transition to establish regions of constitutive heterochromatin. Overall design: 1. Total RNA from passage 4 quiescent MEFs isolated using TRIzol RNA extraction protocol 2. rRNA was depleted from total RNA using the RiboMinus Euk System V2 protocol according to manufacturer’s procotol 3. rRNA-depleted RNA samples were submitted for picoanalyzer analysis to determine concentration, purity, and rRNA content 4. Three wild-type and three mutant RNA samples with <10% rRNA remaining were submitted for library construction 5. Library was used for Illumina HiSeq 2500 paired end sequencing.

Description
RNA-seq libraries were generated on thymic epithelial cell (TEC) subsets from thymic samples (11 days to 3 months of age). Cells were sorted to isolate cortical TEC (cTEC), MHC low medullary TEC (mTEClo) and MHC high medullary TEC (mTEChi). Between 7,575 and 50,000 cells were isolated for each sample. TEC were isolated using CD45 MACS depletion followed by the sorting protocol described in Stoeckler et al. J Vis Exp 2013 (PMID 24084687; doi: 10.3791/50951). The study has been granted ethical approval and is publicly listed (IRAS ID 156910, CPMS 19587). Overall design: 1 sample for each of cTEC, mTEClo and mTEChi were generated on a total of 3 individuals (~50,000 cells per sample) and 3 replicates for each of cTEC, mTEClo and mTEChi were generated on 1 individual (7,575 cells per sample)

Description
Thirty-eight tumors from 17 patients treated with BRAF inhibitor (n=12) or combination BRAF/MEK inhibitors (n=5) with known PD-L1 expression were analyzed. RNA expression arrays were performed on all pre-treatment (PRE, n=17), early during treatment (EDT, n=8) and progression (PROG, n=13) biopsies. HLA-A/HLA-DPB1 expression was assessed by immunohistochemistry (IHC). Gene set enrichment analysis (GSEA) of PRE, EDT and PROG melanomas revealed that transcriptome signatures indicative of immune cell activation were strongly positively correlated with PD-L1 staining. In contrast, MAPK signaling and canonical Wnt/--catenin activity were negatively associated with PD-L1 melanoma expression. The expression of PD-L1 and immune activation signatures did not simply reflect the degree or type of immune cell infiltration, and was not sufficient for tumor response to MAPK inhibition.
