View SamplesAdipogenesis is a complex and precisely orchestrated process mediated by a network of adipogenic regulatory factors. The recent explosion of knowledge have demonstrated that long noncoding RNA are involved in adipogenic gene regulatory network. However, existing annotations of lncRNAs involved in adipogenic differentiation are derived from preadipocyte cell lines, researches using primary cultures of farm animals are obviously required. To comprehensively identify lncRNAs with potential functions during bovine adipogenesis, in the present study we performed Ribo-Zero-Seq to survey the transcriptome landscape of in vitro cultured bovine preadipocytes and differentiated adipocytes. A stringent set of 2882 lncRNAs were finally identified. The 2882 lncRNAs shared many of the features of their mammalian counterparts: relatively shorter in length, significantly lower expression levels and fewer in exon number than RefSeq protein coding transcripts. Comparison of the lncRNAs expression profiles identified 16 specifically regulated lncRNAs during adipogenic differentiation. Integrative computational analyses associated these lncRNAs with several signaling pathways involved in lipid metabolism, including steroid biosynthesis, PPAR signaling pathway, glycolysis/gluconeogenesis, and fatty acid metabolism. Our data provide a valuable genomic resource for the identification of lncRNAs with potential functions in adipogenic differentiation.

View SamplesAs an ancient winning strategy of microorganisms, glucose repression mechanism has become specialized to perfection in Saccharomyces cerevisiae. The galactose (GAL) metabolism network is stringently regulated by glucose repression in yeast and has been a classic system for studying gene regulation. We show here that the population of S. cerevisiae living in fermented milks has autonomously reinstated an ancient version of the structural GAL genes through introgression. The introgressed GAL network has completely abolished the glucose repression and conversed from a strictly inducible to a constitutive system through coordinative polygenic changes in the regulatory components of the network, including transitions in the upstream repressing sequence site of GAL4 that impair Mig1p-mediated repression and loss of function of the inducer Gal3p and the repressor Gal80p. In addition, the introgressed GAL2 gene has been duplicated while the native HXT6 and HXT7 genes have been inactivated, resulting in galactose-over-glucose preference and elevated galactose utilization rate. Relying on the reverse evolution of the GAL network, the non-lactose fermenting yeast has become a dominant species co-existing with other lactose fermenting microorganisms in fermented milks. Our results also provide new clues for developing yeast strains devoid of barriers to co-utilization of different sugars.

View SamplesDNA Topoisomerase I (Top1) relaxes DNA supercoiling and is inhibited with high specificity by camptothecin, a natural product of chinese tree Camptotheca acuminata with anticancer activity. Topoisomerase activity is required at transcribing regions to modulate DNA supercoils generated by RNA polymerases. However, Top1 functions at promoters and molecular responses to CPT are not fully understood. We found that camptothecin increases antisense RNA polymerase II transcripts at active divergent CpG-island promoters in a replication-independent manner. Kinetics investigations of the formation of Top1-DNA cleavage complexes and non-B DNA structures showed that CPT interferes with Top1 modulation of negative DNA supercoiling at promoters. The present findings will be a resource to establish the role of such antisense RNAs in transcription regulation and to discover additional components of the response pathway. Moreover, the transcriptional camptothecin effects can be the molecular basis of the therapeutic activity in cancer as well as neurological syndromes.

View SamplesHepatitis C virus (HCV) infection is primarily treated with a pegylated interferon alpha based therapy, a regime that induces antiviral effects through the upregulation of many interferon-stimulated genes (ISGs). Whilst a number of anti-HCV ISGs have previously been identified, others may also be involved.
