We analysed whole PolyA+ RNA from human osteosarcoma U2OS cells depleted for human Cactin or transfected with a control shRNA. Overall design: Two independent shRNAs targeting human Cactin (shCac_C and shCac_D), a control shRNA (shCtrl), a single cell line (U2OS)
Human cactin interacts with DHX8 and SRRM2 to assure efficient pre-mRNA splicing and sister chromatid cohesion.

View SamplesBPH/5 mice are an inbred strain with “borderline hypertension” that spontaneously develops both maternal and fetal hallmarks of preeclampsia. RNA-Seq analysis of BPH/5 uterine implantation sites at embryonic day 7.5, the peak of decidualization, identifies differential expression of inflammatory response genes, including members of the complement family, compared to C57 controls. Overall design: RNA-Seq was performed on RNA isolated from E7.5 BPH/5 and C57 implantation sites (n=4).

View SamplesOne current focus of nutrition research is the identification of biomarkers that reflect the impact of food on metabolic processes. As this approach mostly targets the prevention rather than the curing of diseases, novel biomarkers need to be identified. Those should be influenced by the diet already in healthy individuals and be nonetheless indicative, or even predictive, of the potential impact of specific food on the development of metabolic diseases such as obesity.

View SamplesAging within the human hematopoietic system associates with increased incidence of anemia and myeloid neoplasms, decreased bone marrow (BM) cellularity and reduced adaptive immune responses. Similar phenotypes have been observed in mice and shown, at least in part, to involve hematopoietic stem cells (HSCs). However, evidence supporting such an association within human hematopoiesis is still sparse and prompted us to detail characteristics of human hematopoietic stem and progenitor cells throughout ontogeny.

View SamplesPKR is an interferon induced serine/threonine protein kinase, that is activated by double stranded RNA. PKR plays an important role in the antiviral defense by interferon. In addition to its role in translation, PKR participates in several signaling pathways to transcription. The goal of this experiment is to study the role of PKR in regulating gene expression in our NIH 3T3 inducible cell line, which could overexpress PKR wt protein after the removal of tetracycline (Donze O, Dostie J, Sonenberg N. (1999) Virology 256: 322-9).

View SamplesReduced cancer incidence has been reported among type II diabetics treated with metformin. Metformin exhibits anti-proliferative and anti-neoplastic effects associated with inhibition of mTORC1, but the mechanisms are poorly understood. We provide the first genome-wide analysis of translational targets of canonical mTOR inhibitors (rapamycin and PP242) and metformin, revealing that metformin controls gene expression at the level of mRNA translation to an extent comparable to that of canonical mTOR inhibitors. Importantly, metformin's anti-proliferative activity can be explained by selective translational suppression of mRNAs encoding cell cycle regulators via the mTORC1/4E-BP pathway. Thus, metformin selectively inhibits mRNA translation of encoded proteins that promote neoplastic proliferation, motivating further studies of this compound and related biguanides in cancer prevention and treatment.
