Spinocerebellar ataxia type 3 (SCA3) is one of the polyglutamine (polyQ) diseases, which are caused by a CAG repeat expansion within the coding region of the associated genes.

View SamplesDrosophila miRNAs show distinct change in isoform distribution pattern with age. Some miRNAs show accumulation of the short isoforms, while other miRNAs show the accumulation of the long isoforms with age. The increase of the long isoforms of some miRNAs reflects increased 2''-O-methylated miRNA isoforms with age. The increase in 2''-O-methylated miRNA isoforms reflected increased Ago2-loading, but not Ago1-loading of specific miRNA isoforms with age. This raised a question on whether there is global shift in small RNA loading pattern between Ago1 and Ago2 with age. To investigate change in small RNA loading pattern between Ago1 and Ago2 with age, we performed small RNA deep-sequencing of Ago1 vs Ago2-IP small RNAs at 3d and 30d in Drosophila. This analysis revealed global increase of miRNA loading into Ago2, but not into Ago1 with age. Overall design: 3d and 30d FLAG-HA-Ago2 male flies were collected. Ago1 and Ago2 were immunoprecipitated by anti-Ago1 and anti-FLAG M2 beads respectively. RNA was purified from the beads, P32-labeled, and small RNA fraction was gel-purififed. Small RNA libraries were prepared using Illumina''s TruSeq small RNA sample preparation kit (#RS-200-0012, Illumina, Inc. San Diego, CA), following the manufacturer''s protocol. The libraries were multiplexed and sequenced on HiSeq2000 platform (Illumina).

View Samplesnbr/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).

View SamplesIL-27 has been shown to play a role in modulating functions of diverse cell types like Th1, Th2, NK and B cells demonstrating both pro and anti-inflammatory roles. It is also capable of inducing STAT1, STAT3 and ISG's. To investigate the role of IL-27 on hepatocytes, Huh7.5 cells were treated with Il-27 and analysed the differentially expressed genes by microarray analysis.

View SamplesThe identification of the most appropriate T-cell subset to ensure optimal persistence and anti-tumor activity is a major goal of cancer immunotherapy. We identified a novel post-mitotic CD45RA+CD62L+ T cell subpopulation (TTN), generated in vitro upon activation of nave T (TN) cells with beads conjugated to anti-CD3 and anti-CD28 antibodies. This cell population is highly proliferative, produces low levels of IFNg and cytotoxic molecules, and requires IL-7 and IL-15 for in vitro expansion.
IL-7 and IL-15 instruct the generation of human memory stem T cells from naive precursors.
