The aim of this study is to assess the global transcriptome changes during the shedding of the flower, which normally takes around 6 or 7 days. We selected four time points (from day 0 to day 6) and three different tissues within the flower bud; distal, abscission and proximal zones with three biological replicates. RNA extraction, library prep and paired end sequencing was performed. Our special interest is try to describe the changes in the abscission zone and the two adjacent tissues in order to get a whole picture of the shedding process. We performed a de novo assembly by Trinity and detected the transcripts and expression changes across spatial and temporal comparisons.

Studies have shown that Rice Salt Sensitive 1 (RSS1) is involved in stress response in rice plants. Primers were developed for amplification via Polymerase Chain Reaction (PCR) of a region that contained a simple sequence repeat (SSR) in RSS1. PCR was performed on 6 different varieties of Oryza sativa. PCR product was sequenced on an ABI 3730 capillary sequence machine. Sequence data was aligned to observe differences in SSR length between each rice variety.

Acute myeloid leukemia (AML) is the most common and severe acute leukemia diagnosed in adults. Although it is one of the most studied cancers, this is the first study of Polish population of AML patients. The data were collected with the use of home-made boutique array. The additional advantage is pre-selection of patients - our sample set includes only two AML FAB subtypes with the highest content of immature myeloid cells: M1 (11 samples) and M2 (22 samples). From the majority of patients two sources of material were used for mononuclear cell separation and RNA extraction: bone marrow and peripheral blood. 15 samples from healthy volunteers were used as a control.

6-year-old ramets of U. minor (Atinian elm clone) were inoculated with O. novo-ulmi in order to evaluate molecular responses activated during plant colonization. To elucidate the different genes involved in the U. minor immune system and the molecular changes suffered after inoculation, oligomicroarrays were constructed using the data from the transcriptome available in the Dryad database (Perdiguero et al., 2015; http://dx.doi.org/10.5061/dryad.ps837), and hybridized with cDNA obtained from the ramets over a time course following inoculation. Three biological replicates for control and inoculated plants for each sampling point (1, 3, 7, 14 and 21 days post-inoculation) were hybridised using two colors (inoculated vs control).

Human cartilage taken from young normal knees following anterior cruciate ligament repair and osteoarthritic cartilage following total knee arthroplasty. Total RNA extracted using mirVana miRNA isolation kit (Life Technologies). The Affymetrix Flash Tag labelling kit was used to prepare samples for hybridisation onto Affymetrix miRNA 4.0 arrays.

This is a pilot study from the Knockout Mouse Phenotyping Program (KOMP2). The program provides broad, standardized phenotyping of a genome-wide collection of mouse knockouts generated by the International Knockout Mouse Consortium (IKMC), funded by the NIH, European Union, Wellcome Trust, Canada, and the Texas Enterprise Fund. In this experiment RNAseq was performed to profile expression of coding RNA in the liver, spleen, kidney, abdominal muscle and gonadal adipose tissue of knock out mice (1810027O10Rik knockout, Sik1 knockout, 3110043O21Rik knockout, 3110043O21Rik knockout) compared with wild type controls.

Daunorubicin (DNR) and Cytarabin (Ara-C) are the main chemotherapeutic drugs used for Acute Myeloid Leukemias (AML) treatment. However, their mode of action is not well understood. To decipher if these drug would induce rapid transcriptional reprogramming, we treated HL-60 AML cell line with DNR or Ara-C for 3 hours and carried out a transcriptomic analyses. In addition, we had shown that Reactive Oxigen Species (ROS) produced by NADPH oxidases (NOX) are involved in DNR-induced gene expression. We therefore also performed a transcriptomic analyses in HL-60 cells treated with DNR and VAS2870, an NADPH oxidase inhibitor. HL-60 cells were treated or not for 3 hours with 2 µM Ara-C, 1 µM DNR or 1 µM DNR + 20µM VAS 2870. RNAs were purified from 3 independent experiments and used to probe Affymetrix Human Gene 2.0 ST Genechips
