Description
c-Fos, a member of the stress-activated Activator Protein 1 (AP-1) transcription factor family, is expressed in human hepatocellular cancer (HCC). Using genetically engineered mouse models (GEMMs) we show that hepatocyte-specific expression of c-Fos leads to a proliferative, de-differentiated phenotype, whereas hepatocyte-specific deletion of c-Fos protects against diethylnitrosamine (DEN)-induced liver cancer. Furthermore, c-Fos-expressing livers resemble human HCCs based on expression profiles. In the present RNA seq, we intend to analyze the transcriptomic profile of livers at 2 and 4 mo hepatocyte-specific c-Fos expression compared to the corresponding age-matched control mice. Moreover, we analyzed livers of mice with hepatocyte-specific deletion c-Fos at 48h after DEN treatment compared to identically treated control mice. Overall design: The general idea was to analyze the transcriptomic profile of hepatocyte-specific c-Fos over-expressing livers at 2 and 4 mo expression. Hereby, a hepatocyte-specific doxycycline (Dox)-switchable mouse model was (LAP-tTA; col1a1:Tet-O-fosFlag) was generated and c-Fos expression was induced at the age of 3 weeks by removal of doxycycline. Each sample LaptTA-fos-MUT represents an individual hepatocyte-specific c-fos expressing mouse at the indicated time-point and the corresponding identically treated control mouse LaptTA-fos-CO. Moreover, the transcriptomic profile of livers with hepatocyte-specific deletion of c-Fos at 48h after diethylnitrosamine (DEN)-induced liver cancer initiation was analyzed. For hepatocyte-specific knock-out of c-Fos, mice with conditional alleles of c-fos and the Alfp-Cre transgene were used. Control mice only carried the Alfp-Cre transgene. At the age of 8 weeks these mice were injected with 100mg/kg DEN. Each sample AlfpCre-fos-MUT_DEN represents an individual hepatocyte-specific c-fos knock-out mouse 48h after DEN and the identically treated control mouse AlfpCre-fos-CO-Cre+_DEN.

Description
The female germline undergoes a unique line of differentiation processes that endows totipotency to the egg. During these processes, biologically significant events such as meiosis and oocyte growth are controlled in an orderly manner, with any disorder causing infertility and developmental arrest of the next generation. Reconstitution in vitro of the entire process of oogenesis from pluripotent stem cells is a key achievement in stem cell biology and regenerative medicine, but a robust and reproducible culture system has not been established. Here, we report successful reconstitution in vitro throughout the entire process of oogenesis from pluripotent stem cells, yielding in vitro-produced eggs that gave rise to healthy pups. Moreover, the pluripotent stem lines were re-derived from the in vitro-generated eggs, thereby reconstituting one generation on a dish. This culture system will provide a unique platform for elucidating the molecular mechanisms underlying totipotency and could open an avenue to producing vast numbers of eggs in vitro. Overall design: The transcriptomes of ES cells (ESCs), primordial germ cell-like cells at day 6 of differentiation (PGCLCs_d6), PGCLCs aggregated with gonadal somatic cells (PGCLCs_agg3), in vitro-produced primary oocytes in secondary follicles (vitro_2nd_fol_oocyte) and MII oocytes (vitro MII oocytes) are determined by RNA-seq analysis. For comparison, the transcriptomes of E12.5 PGCs (vivo_E12.5_PGCs), P8 primary oocytes (vivo_2nd_fol._oocyte) and MII oocytes (vivo_MII_oocyte) in vivo are also determined. Biologically triplicated (rep1-3) or duplicated (rep1-2) samples are sequnced simultaneously.

Description
Rhizoctonia solani is an economically important soil-borne necrotrophic fungal pathogen, with a broad host range and for which little effective resistance exists in crop plants. Arabidopsis is resistant to the R. solani AG8 isolate but susceptible to R. solani AG2-1. Affymetrix microarray analysis was performed to determine genes that are affected in common and specifically by AG8 and AG2-1.

Description
In the present study, we investigated the effect of CBM 588 on lifespan and multiple-stress resistance using Caenorhabditis elegans as a model animal. When adult C. elegans were fed a standard diet of Escherichia coli OP50 or CBM 588, the lifespan of the animals fed CBM 588 was significantly longer than that of animals fed OP50. Moreover, the worms fed CBM 588 were more resistant to certain stressors, including infections with pathogenic bacteria, UV irradiation, and the metal stressor Cu2+. CBM 588 failed to extend the lifespan of the daf-2/IR, daf-16/FOXO and skn-1/Nrf2 mutants. Transcriptional profiling comparing CBM 588-fed and control-fed animals suggested that DAF-16-dependent class II genes were regulated by CBM 588. In conclusion, CBM 588 extends the lifespan of C. elegans probably through regulation of the insulin/IGF-1 signaling (IIS) pathway and the Nrf2 transcription factor, and CBM 588 improves resistance to several stressors in C. elegans. Overall design: Transcriptional profiling of eight-day-old worms that were fed OP50 or CBM 588 for five days, by deep sequencing, using Illumina HiSeq.
