Description
It remains unclear how epigenetic modulators impact the tumorigenic potential of Myc. Here we show that the core subunits, including Dpy30, of the major H3K4 methyltransferase complexes are selectively upregulated in Burkitt lymphoma, and Dpy30 is important for efficient genomic binding of Myc. Dpy30 heterozygosity does not affect normal animal physiology, but significantly suppressed lymphomagenesis and reduced expression of a subset of key pro-survival genes when Myc is hyper-activated. Dpy30 heterozygosity also impedes cellular transformation without affecting normal cell growth. These results suggest that Myc hijacks this chromatin modulator to coordinate its oncogenic program for efficient tumorigenesis, meanwhile creating epigenetic vulnerability, which we then exploited by specifically targeting Dpy30s activity to inhibit growth of the Burkitt lymphoma cell model.

Description
RNA-Seq is an effective method to study the transcriptome, but can be difficult to apply to scarce or degraded RNA from fixed clinical samples, rare cell populations, or cadavers. Recent studies have proposed several methods for RNA-Seq of low quality and/or low quantity samples, but their relative merits have not been systematically analyzed. Here, we compare five such methods using a comprehensive set of metrics, relevant to applications such as transcriptome annotation, transcript discovery, and gene expression. Using a single human RNA sample, we constructed and deeply sequenced 10 libraries with these methods and two control libraries. We find that the RNase H method performed best for low quality RNA, and can even effectively replace oligo (dT) based methods for standard RNA-Seq. SMART and NuGEN had distinct strengths for low quantity RNA. Our analysis allows biologists to select the most suitable methods and provides a benchmark for future method development. Overall design: Examination of 9 different RNA-Seq libraries starting from total RNA from 5 distinct methods; also 3 control RNA-Seq libraries

- Affymetrix Rat Expression 230A Array (rae230a)
Description
This study aims at a comprehensive understanding of the genomic program activated during early-phase of collateral vessel growth in a rat model for cerebral adaptive arteriogenesis (3-VO). While arteriogenesis constitutes a promising therapeutic concept for cerebrovascular ischemia, genomic profiles essential for therapeutic target identification were analysed solely for collateral arteries of the heart and periphery. Despite challenging anatomical conditions of the brain the 3-VO model allows identification of differentially expressed genes during adaptive cerebral arteriogenesis by selective removal of the posterior cerebral artery (PCA).

Induction of cerebral arteriogenesis leads to early-phase expression of protease inhibitors in growing collaterals of the brain.

Description
Administration of exogenous mesenchymal stem cells (MSCs) has been shown to improve the recovery from acute kidney injury (AKI). It has been suggested that the beneficial effect of MSCs is related to the paracrine release of factors favouring proliferation of intrinsic epithelial cells survived to injury rather than to their trans-differentiation. However the factors involved remain to be determined. In the present study we demonstrated that microvesicles (MVs) derived from human bone marrow MSCs are able to stimulate in vitro proliferation and apoptosis resistance of tubular epithelial cells (TEC). In addition, MVs were found to accelerate in vivo the morphological and functional recovery of glycerol induced AKI in SCID mice by inducing TEC proliferation. The effect of MVs on the recovery of AKI was comparable to that of human MSC treatment. In vitro we found that the CD44 and beta1-integrin-dependent incorporation of MVs in TEC was required for their biological action. However, despite their internalization, RNase-treated MVs failed to induce in vitro apoptosis resistance and TEC proliferation, and in vivo recovery from AKI, suggesting an RNA-dependent biological effect. Microarray analysis and quantitative RT-PCR of MV-RNA extract indicated that MVs were shuttling a specific subset of cellular mRNA, such as mRNA associated with the mesenchymal differentiative phenotype and with several cell functions involved in the control of transcription, proliferation, apoptosis and cell immune regulation. These results suggest that MVs derived from MSCs may activate a proliferative program in TEC survived to injury in AKI by an horizontal transfer of mRNA.
