Project description:Excisional biopsies of lymph nodes involved by follicular lymphoma (FL) were obtained from previously-untreated, advanced-stage patients to generate heterohybridomas and idiotype vaccine for a clinical trial (PMID: 21632504). Residual, viably-cryopreserved suspensions of disaggregated cells were magnetically sorted by negative selection into nominal B (CD3-depleted) and non-B (NB; CD19- and CD20-depleted) fractions. Total RNA was extracted from each fraction for separate gene expression profiling (GEP). Technically-satisfactory GEP results were obtained from both fractions for 43 patients.
Project description:Cell body and pseudopod RNA are differentially regulated during the migration of the metastatic cancer cells.We wanted to identify the RNA which are upregulated in the pseudopodial (PS) fraction as compared to cell body fraction (CB). We used microarray to see which are the RNAs upregulated in the PS fraction as compared to CB fraction PS and CB fractions were isolated from six different metatstatic cell lines

Project description:In order to select mRNA transcripts strongly enriched in murine white adipocytes versus brown adipocytes or stromal-vascular fraction, gene expression data of the adipocyte and stromal-vascular fractions of the interscapular brown, inguinal subcutaneous as well as visceral epididymal adipose tissue depots of young adult male C57BL/6 mice housed at constant 23°C ambient temperature were obtained.

Project description:Eukaryotic genomes contain various types of small non-coding RNAs such as microRNAs (miRNAs), silencing RNAs (siRNAs) and PIWI-interacting RNAs (piRNAs). Recent studies point to the presence of a more diverse array of uncharacterized small regulatory RNAs including those that are generated from mRNAs, rRNAs and tRNAs. To explore the possible involvement of tRNA-derived fragments (tRFs) in translational regulation, we fractionated 1 and 8h Drosophila embryos on sucrose density gradients and quantitatively measured by deep-dequencing the expression levels of the tRFs in the fractionated and unfractionated Drosophila embryonic cytosolic extracts. Analysis of 9,007,661 reads has revealed that tRFs, which are produced mainly from the 5’ends of a subset of tRNAs, are mostly associated with the non-polysomal fractions in Drosophila embryos. Quantitative analysis indicates that the expression levels of a subset of tRFs change temporally following the maternal-tozygotic transition in embryos. We detected non-polysomal association of tRFs in S2 cells as well. When transfected into S2 cells, the biotinylated tRFgly:GCC:5 co-fractionated with the non-polysomal complexes similar to the endogenous tRFgly:GCC:5 in embryos and S2 cells. These results suggest that the tRFs, which are much smaller in size than the stres-induced tRNA fragments, are generated selectively from a fraction of tRNAs and that they associate primarily with the non-polysomal complexes in Drosophila embryos and S2 cells.
Project description:Cord blood (CB) samples from normal donors were obtained with informed consent. Fresh CB samples were processed within 18-34h after collection. Mononuclear cells were isolated and CD34+ fraction was separated. CB CD34+ enriched fraction was lineage depleted by staining with purified anti-human CD2, CD3, CD4, CD7, CD8a, CD11b, CD14, CD19, CD20, CD56, CD235a followed by Qdot 605 conjugated goat F(ab')2 anti-mouse IgG (H+L). Cells were also stained with anti-human CD38-FITC, CD45RA-PE or -BV650, CD123-PE Cy7, CD90-biotin, CD34- PerCP and CD10-APC. Finally, cells were incubated with streptavidin-conjugated APC-eF780 and Hoechst 33258 (Invitrogen, final concentration: 1 g/ml). Populations were defined, as follows: HSC - Lin-CD34+CD38-CD90+CD45RA-CD10-, MPP - Lin-CD34+CD38-CD90-CD45RA-CD10-, LMPP - Lin-CD34+CD38-CD90-/loCD45RA+CD10-, MLP - Lin-CD34+CD38-CD90-/loCD45RA+CD10+, GMP - Lin-CD34+CD38+CD123+CD45RA+CD10-, CMP - Lin-CD34+CD38+CD123+CD45RA-CD10-, MEP - Lin-CD34+CD38+CD123-CD45RA-CD10-.
