Description
Deleted in Azoospermia Associated Protein 1 (DAZAP1) is a ubiquitous RNA-binding protein that is highly expressed in the testis. It is a component of the hnRNP particles and shuttles between the nucleus and the cytoplasm. Mice expressing the DAZAP1-Fn mutant protein manifest both growth retardation and spermatogenic arrest before meiosis I. To elucidate the biological function(s) of DAZAP1 and to search for its natural RNA substrates, we compared the expression profiles of wild-type and Dazap1 mutant testes by cDNA microarrays.

Description
Resistance of Calu3 NSCLC cells to the cytotoxic nucleoside analog gemcitabine (2',2'-difluorodeoxycytidine) can be prevented as well as reversed by the rexinoid X receptor selective agonist bexarotene. This study was designed to investigate the changes in gene expression associated with gemcitabine resistance and its reversal by bexarotene. In addition to the parental Calu3 cells and the 10 cycles of treatment of the gemcitabine resistant Calu3 cells with vehicle or bexarotene, analogous treatment paradigms with gemcitabine alone as well as the combination of both compounds have been included as controls. (However, it has to be noted that in the combination treatment, cells that were re-sensitized by bexarotene have largely been removed from the culture before harvest due to the cytotoxic activity of gemcitabine.)

Bexarotene (LGD1069, Targretin), a selective retinoid X receptor agonist, prevents and reverses gemcitabine resistance in NSCLC cells by modulating gene amplification.

Description
Biological effects of overexpression of miR-146b microRNAs in the A549 human lung cancer cell-line was studied. A549 cells were engineered to express the precursor RNA (pre-miR-146b) that generates the miR-146b microRNAs. Control cells were engineered using the same gene expression plasmid (pLemiR, Open Biosystems) but without the pre-miR-146b insert. The Trans-Lentiviral GIPZ packaging system (Open Biosystems) was used to generate stable transfectant populations of the engineered cells.
Publication Title
Overexpression of the lung cancer-prognostic miR-146b microRNAs has a minimal and negative effect on the malignant phenotype of A549 lung cancer cells.

Description
We used RNA-seq to interrogate prostate cancer specific gene fusions, alternative splicings, somatic mutations and novel transcripts. Overall design: We sequenced the transcriptome (polyA+) of 20 prostate cancer tumors and 10 matched normal tissues using Illumina GAII platform. Then we used bioinformatic approaches to identify prostate cancer specific aberrations which include gene fusion, alternative splicing, somatic mutation, etc.

Description
We used a novel approach to study the acute effect of three physiologic stressors (active contractions, vibration, and systemic heat stress) in human skeletal muscle. Three hours after the completion of a dose of physiologic stress, we sampled the soleus (contraction and vibration) or vastus lateralis (heat) muscle and developed a unique gene expression signature for each stressor. We discovered repetitive active muscle contractions up regulated metabolic transcription factors NR4A3 (12.45 fold change), PGC-1 (5.46 fold change), and ABRA (5.98 fold change); and repressed MSTN (0.56 fold change). Heat stress repressed PGC-1 (0.74 fold change); while vibration induced FOXK2 (2.36 fold change). Vibration similarly caused a down regulation of MSTN (0.74 fold change), but to a lesser extent than active muscle contraction. Vibration induced FOXK2 while heat stress repressed PGC-1 (0.74 fold change) and ANKRD1 genes (0.51 fold change). These findings support a distinct gene regulation in response to heat stress, vibration, and muscle contractions. Understanding these responses may assist in developing regenerative rehabilitation interventions to improve muscle cell development, growth, and repair.

Description
ATP-dependent chromatin remodeling complexes are essential for transcription regulation, and yet it is unclear how these multisubunit complexes coordinate their activities to facilitate diverse transcriptional responses. In this study, we found that the conserved Arp5 and Ies6 subunits of the Saccharomyces cerevisiae INO80 chromatin-remodeler form an abundant and distinct subcomplex in vivo and stimulate INO80-mediated activity in vitro. Moreover, our genomic studies reveal that the relative occupancy of Arp5-Ies6 correlates with nucleosome positioning at transcriptional start sites and expression levels of >1,000 INO80- regulated genes. Notably, these genes are significantly enriched in energy metabolism pathways. Specifically, arp5d, ies6d, and ino80d mutants demonstrate decreased expression of genes involved in glycolysis and increased expression of genes in the oxidative phosphorylation pathway. Deregulation of these metabolic pathways results in constitutively elevated mitochondrial potential and oxygen consumption. Our results illustrate the dynamic nature of the INO80 complex assembly and demonstrate for the first time that a chromatin remodeler regulates glycolytic and respiratory capacity, thereby maintaining metabolic stability. Overall design: RNA-Seq was performed on two biological replicates of each of the following yeast strains: WT (BY4741), ino80del, arp8del, arp5del, and ies6del.
