04). Tall vein inoculation of RM-9 cells produced significantly more experimental lung metastases in PBcav-1

males than in nontransgenic male littermates (P = 0.001), and in cav-1(+/+) AZD1208 cost mice than in cav-1(-/-) mice (P = 0.041). Combination treatment with surgical castration and systemic cav-1 antibody dramatically reduced the number of experimental metastases. These experimental data suggest a causal association of secreted cav-1 and prostate cancer growth and progression. (Mol Cancer Res 2009;7(9):1446-55)”
“Upstream of N-ras (UNR) is a conserved RNA-binding protein that regulates mRNA translation and stability by binding to sites generally located in untranslated regions (UTRs). In Drosophila, sex-specific binding of UNR to msl2 mRNA and the noncoding RNA roX is believed to play key roles in the control of X-chromosome dosage compensation in both sexes. To investigate broader sex-specific functions of UNR, we have identified its RNA targets in adult male and female flies by high-throughput RNA binding and transcriptome analysis. Here we show that UNR binds to a

large set of protein-coding transcripts and to a smaller set of noncoding RNAs in a sex-specific fashion. FG-4592 The analyses also reveal a strong correlation between sex-specific binding of UNR and sex-specific differential expression of UTRs in target genes. Validation experiments indicate that UNR indeed recognizes sex-specifically processed transcripts. These

results suggest that UNR exploits the transcript diversity generated by alternative processing and alternative promoter usage to bind and regulate target genes in a sex-specific manner.”
“The chemical composition and in vitro antioxidant capacity (AC) of the two most commercialized species of jaboticaba, Sabara (Myrciaria jaboticaba) and Paulista (Myrciaria cauliflora), were compared in different fruit parts (skin, pulp and seeds) and at different ripening stages. Both species presented similar mineral and centesimal compositions, and were found to be rich sources of Mn (1.8-2.7 mg/100 g DW) and Cu (1.0 mg/100 g DW). Except for anthocyanins, phenolic concentrations were in greater amounts in Sabara than in Paulista. Ellagic acid derivatives Roscovitine in vivo (EA) contents varied according to ripening stage and also across fruit parts (skin, pulp and seeds). Unripe jaboticaba showed the highest contents of proanthocyanidins (PAC) and ellagitannins, as well as the greatest antioxidant capacity. Complete ripening led to a decrease of 47% in total EA, 43% in PAC, 60-77% in AC. Seeds displayed the highest concentrations of ellagitannins and proanthocyanidins and the greatest AC, whereas skin exhibited the highest amounts of anthocyanins and quercetin derivatives. Phenolics strongly inhibited carbohydrate-digesting enzymes.
