Description
The comparison of trancriptomes was part of the study by Pasternak et al. The goal was to check if BTG4 regulates mRNA polyadenylation during mouse oocyte meiosis. To test this we compared the abundancies of the polyadenylated trancripts in control and Btg4-depleted oocytes. Overall design: 3 samples of 50 oocytes were collected for both groups

Description
The comparison of trancriptomes was part of the study by Pfender, Kuznetsov, Pasternak et al, titled: "Live imaging RNAi screen reveals genes essential for meiosis in mammalian oocytes". The goal was to check if the oocytes cultured in vitro in follicles (for RNAi studies) correspond to real gametes obtained directly from mice (in vivo). Apart from functional experiments showing that they can be fertilized and develop into an embryo, we also compared transcriptomes of those oocytes. Overall design: 3 samples of 50 oocytes were collected for both groups of in vitro and in vivo grown oocytes.

Description
A majority of individuals infected with human immunodeficiency virus (HIV) have inadequate access to antiretroviral therapy and ultimately develop debilitating oral infections that often correlate with disease progression. Our study evaluates the potential of simian immunodeficiency virus (SIV) infected rhesus macaques to serve as a non-human primate model for oral manifestations of HIV disease.

Description
A majority of individuals infected with human immunodeficiency virus (HIV) have inadequate access to antiretroviral therapy and ultimately develop debilitating oral infections that often correlate with disease progression. Our study evaluates the impact of chronic exposure to the pro-inflammatory cytokine, interferon gamma, on the growth and barrier functions of the oral epithelium.

Description
The Epidermal Growth Factor Receptor (EGFR)/ligand system is centrally involved in multiple homeostatic functions of the epithelia. Epithelial cells are the primary targets of humanized antibodies and small molecule inhibitors against this system, whereby the constellation of skin-specific side effects of these drugs stems from a profound disturbance of keratinocyte biology. So far, the molecular mechanisms underlying these toxic events have been investigated only broadly. Here we show that keratinocyte response to anti-EGFR drugs comprises the development of a type 1 interferon (IFN) molecular signature including enhanced expression of IFN-kappa. Mechanistically, nuclear accumulation of IRF1 precedes this signature as well as the enhanced expression of a chemokine cluster we previously identified as a relevant pro-inflammatory component of EGFR inhibition. In fact, either silencing of IRF1 transcript expression, or antibody-mediated blockade of type 1 IFN receptor function and consequent abrogation of STAT1 activation, leads to impairment of this gene transcription profile. High levels of IRF1 and IFN-kappa can be clearly observed in the early skin lesions of patients treated with cetuximab. Type 1 IFN signaling could be crucially implicated in the triggering of the inflammatory mechanisms active in the skin of patients under treatment with anti-EGFR drugs.

Description
Increased miR-135a levels are observed in human patients with temporal lobe Epilepsy (TLE) and in experimental animal models. Upon targeting the increased miR-135a levels in vivo using antagomirs in kainic acid induced status epilepticus mouse model of TLE, we observed a strong reduction of spontaneous recurrent seizures. To understand this further and to find target mRNAs that potentially mediate the seizure suppressive function of miR-135a, we performed immunoprecipitation using biotin tagged miRNA mimics, followed by RNAsequencing (RNAseq). We found several novel neuronal targets of miRNA-135a and identified Mef2a as a key target in this study. Here we report the total RNAseq data. Overall design: N2A cells were transfected with biotin tagged miRNA mimics for miR-135a and negative control and immunoprecipitations were performed. N = 3 replicates of IP and input samples for each condition were generated and sequenced on illumina platform for total RNA for identification of novel targets of miR-135a.

Description
We investigated the occupancy of RNA PolII and INTS11 during the stimulation of EGF and compared with drug treated condition using inhibitors against MAPK pathway and Integrator. Additionally, we examined transcription by sequencing the chromatin-bound fraction of RNA. Overall design: We employed several cel lines in our experiment, including HELA, KRAS mutant lung cancer cell line A549 and BRAF mutatant melanoma cell line A375. The conditons we checked including EGF stimulation, MAPK pathway inhibition using BRAF, MEK or ERK inhibitiors, targeting INTS11 with RNAi or integrator inhibitor. We used RNA sequencing to measure the expression profile and CHIP sequencing to detect INTS11 and RNA PolII recruitment on chromatin.
