Description
We have identified genes that are differentially expressed between the bladders of UPII-SV40Tag mice and their age-matched wild-type littermates at 3, 6, 20, and 30 weeks of age. These are ages that correspond to premalignant, carcinoma in situ, and early-stage and later stage invasive UCC, respectively

Description
The circadian clock generates daily rhythms in mammalian liver processes, such as glucose and lipid homeostasis, xenobiotic metabolism, and regeneration. The mechanisms governing these rhythms are not well understood, particularly the distinct contributions of the cell-autonomous clock and central pacemaker to rhythmic liver physiology. Through microarray expression profiling in MMH-D3 hepatocytes, we identified over 1,000 transcripts that exhibit circadian oscillations, demonstrating that many rhythms can be driven by the cell-autonomous clock and that MMH-D3 is a valid circadian model system. The genes represented by these circadian transcripts displayed both co-phasic and anti-phasic organization within a protein-protein interaction network, suggesting the existence of competition for binding sites or partners by genes of disparate transcriptional phases. Multiple pathways displayed enrichment in MMH-D3 circadian transcripts, including the polyamine synthesis module of the glutathione metabolic pathway. The polyamine synthesis module, which is highly associated with cell proliferation and whose products are required for initiation of liver regeneration, includes enzymes whose transcripts exhibit circadian oscillations, such as ornithine decarboxylase (Odc1) and spermidine synthase (Srm). Metabolic profiling revealed that the enzymatic product of SRM, spermidine, cycles as well. Thus, the cell-autonomous hepatocyte clock can drive a significant amount of transcriptional rhythms and orchestrate physiologically relevant modules such as polyamine synthesis.

Description
nbr/CG9247 gene regulates 3''end heterogeneity of a subset of miRNAs. It is not clear how broad this effect is on small RNA population. To address this, we compared small RNA population in wild-type and tmr[f02257] mutants. This approach identified more miRNAs whose 3''end heterogeneity was affected in nbr[f02257] mutants. Overall design: 2-3 day old control (w homogeneous strain Bloomington stock center 5905) and nbr[f02257] null mutant flies were collected. nbr[f02257] line was in the homogenous (Bloomington stock center stock 5905) background through a minimum of 5 backcrosses. Total RNA from whole flies was extracted using TRIzol reagent (Invitrogen). 40ug of total RNA from each genotype was used for small RNA library preparation with Small RNA Sample Prep kit (v1.5) (Illumina).

Description
Frankincense oil is prepared from aromatic hardened wood resin obtained by tapping Boswellia trees. For thousands of years, it has been important both socially and economically as an ingredient in incense and perfumes. Frankincense oil is a botanical oil distillate made from fermented plants that contains boswellic acid, a component known to have anti-neoplastic properties. We evaluated frankincense oil-induced cytotoxicity in bladder cancer cells. With a window of concentration, frankincense oil suppressed cell viability and induced cytotoxicity in bladder transitional carcinoma J82 cells but not normal bladder urothelial UROtsa cells immortalized with SV40 large T antigen. However, frankincense oil-induced J82 cell death did not result in DNA fragmentation. Microarray and bioinformatics analysis confirmed that frankincense oil activated cell cycle arrest, suppressed cell proliferation, and activated apoptosis in J82 cells through a series of potential pathways. These finding suggest that bladder cancer can be treated through intravesical administration of pharmaceutical agents similar to direct application on melanoma.

Description
We report the cloning and sequencing of both endogenous small RNAs and virus-derived siRNAs produced by the antiviral RNAi pathway in Drosophila. We find that a diverse panel of viruses are targeted by the RNAi pathway in Drosophila to produce abundant virus-derived siRNAs, and these siRNAs map to various locations within the viral genomes. Knockdown of various RNAi and miRNA pathway components alters the levels of these viral small RNAs. Overall design: Drosophila DL1 cells were treated with dsRNA for 3 days to deplete factors involved in the antiviral RNAi pathway and miRNA pathway, then were challenged with one of four viruses for 4 days. Total RNA was collected, and the small RNA populations from 15-29 nt were cloned and sequenced.
