Description
Renin, a key component in the regulation of blood pressure in mammals, is produced by the rare and highly specialized juxtaglomerular (JG) cells of the kidney. Although these cells line the media of the glomerular afferent arterioles and share some characteristics with contractile cells, they are filled with lysosome-like organelles where renin is activated and stored for regulated secretion in response to physiological and pathophysiological stimuli. Chronic stimulation of renin release results in a recruitment of new JG cells by the seeming conversion of adjacent smooth muscle cells along the afferent arterioles. Because JG cells rapidly de-differentiate when removed from the kidney, their developmental origin and the mechanism that explains their phenotypic plasticity remain largely unclear. In an effort to overcome this limitation, we have performed RNA expression analysis on four human renin-producing tumors. The most highly expressed genes that were common between the reninomas were subsequently used for in situ hybridization in mouse kidney. Our results add 40 new genes to the list that characterize renin-producing cells and reveal a significant variation in the expression patterns of developing, mature and recruited JG cells. Overall design: RNA-Seq was performed with a HiSeq 2000 on three biopsies of a first reninoma from Paris (Par1B1-B3), one biopsy from a reninoma from Montreal (Mon), two biopsies from a reninoma from Rotterdam (RotB1, B2), and a second reninoma from Paris (Par2) along with a biopsy from adjacent supposedly normal tissue from the same patient (Par2N).

Description
Efforts to unravel the mechanisms underlying taste sensation (gustation) have largely focused on rodents. The first comprehensive database of gene expression in primate (Macaca fascicularis) taste buds is presented. This database provides a foundation for further studies in diverse aspects of taste biology. A taste bud gene expression database was generated using laser capture microdissection (LCM) of tissue freeze medium OTC embedded macaque tongue tissue blocks. We collected fungiform (FG) taste buds at the front of the tongue, circumvallate (CV) taste buds at the back of the tongue, as well as non-gustatory lingual epithelium (LE). Gene expression was also analyzed in the top and bottom portions of CV taste buds collected using LCM. Samples were collected from 10 animals - 7 female, 3 male.

AS2 encodes a protein containing AS2 domain and epigenetically regulate transcription. RH10 encodes an ortholog of human DEAD-box RNA helicase DDX47. These genes are involved in the formation of axes of leaves of Arabidopsis thaliana. To know the gene regulation in the leaf development, expression profile among wild-type, as2, rh10 and as2 rh10 double mutant plants were compared.

Description
c-MYC (MYC) overexpression or hyperactivation is one of the most common drivers of human cancer. Despite intensive study, the MYC oncogene remains recalcitrant to therapeutic inhibition. Like other classic oncogenes, hyperactivation of MYC leads to collateral stresses onto cancer cells, suggesting that tumors harbor unique vulnerabilities arising from oncogenic activation of MYC. Herein, we discover the spliceosome as a new target of oncogenic stress in MYC-driven cancers. We identify BUD31 as a MYC-synthetic lethal gene, and demonstrate that BUD31 is a splicing factor required for the assembly and catalytic activity of the spliceosome. Core spliceosomal factors (SF3B1, U2AF1, and others) associate with BUD31 and are also required to tolerate oncogenic MYC. Notably, MYC hyperactivation induces an increase in total pre-mRNA synthesis, suggesting an increased burden on the core spliceosome to process pre-mRNA. In contrast to normal cells, partial inhibition of the spliceosome in MYC-hyperactivated cells leads to global intron retention, widespread defects in pre-mRNA maturation, and deregulation of many essential cell processes. Importantly, genetic or pharmacologic inhibition of the spliceosome in vivo impairs survival, tumorigenicity, and metastatic proclivity of MYC-dependent breast cancers. Collectively, these data suggest that oncogenic MYC confers a collateral stress on splicing and that components of the spliceosome may be therapeutic entry points for aggressive MYC-driven cancers.

Description
Gan mice express Wnt1, Ptgs2, and Ptges, which develop inflammation-associated gastric tumors (Oshima et al, Gastroenterology 131: 1086, 2006). We examined the role of MyD88 in tumorigenesis by construction of Myd88-/- Gan mice and bone marrow transplantation into Gan mice from Myd88-/- mice. Overall design: Total RNA was prepared from wild-type normal glandular stomach (n=3: WT 1–WT 3), B6 C2mE mice (n=3: C2mE 1–C2mE 3), B6 Gan mice (n=3: Gan1–Gan3), B6 Gan MyD88-/- mice (n=3: Gan 1 (MyD88-/-)–Gan 3 (MyD88-/-)), and B6 bone marrow transplanted Gan mice from Myd88-/- mice (n=3: BMT-Gan 1 (from MyD88-/-)–BMT-Gan 3 (from MyD88-/-)). We used Illumina HiSeq 2000, and examined expression profiles.
