High-throughput transcriptome sequencing of an AML-M2 patient in two stages: primary tumor and remission.

ABSTRACT: In order to detect the transcriptomic differences during chemotherapy treatment of de novo AML, we adopted massively parallel pyrosequencing of mRNAs (RNA-seq) using blood tissues of an patient with AML (FAB subtype M2) in tumor stage and remission stage. We obtained a total of 34.6 and 30.8 million paired reads from the two samples. The RNA-seq data derived from the sample illustrated the differentially expression genes between the two stages. Blood samples of an AML-M2 patient in two stages examined: primary tumor and chemotherapy induced remission.

Expression profiling of E14 cells overexpressing Hk2/Pkm2

Project description:Purpose: In this study, we compared transcriptome profiling (RNA-seq) between normal mouse embryonic stem cell (E14) and Hexokinase2 (Hk2)/ Pyruvate Kinase M2 (Pkm2) overexpressed E14 cell. Result: Using an optimized data analysis workflow, we mapped over 4 billion sequence reads per sample to the mouse genome (build mm9) and identified 28698 transcripts in 5 samples. Conclusion: Our study represents the first detailed analysis of Hk2/ Pkm2 overexpressed E14 cell transcriptomes, generated by RNA-seq technology We compared transcriptome profiling (RNA-Seq) between normal mouse embryonic stem cell (E14) and E14 cells over-expressing Hexokinase2 (Hk2)/Pyruvate Kinase M2 (Pkm2)

Transcriptome of normal, paracancerouse and cancerous bladder tissues based on RNA-Seq method

Project description:In order to support our research of bladder cancer in human genome, we conducted massively parallel pyrosequencing of mRNAs (RNA-Seq) using normal, paracancerouse and cancerous human bladder tissues. We obtained a total of 30.0 million read pairs from normal, 33.1 million read pairs from paracancerous and 36.5 million read pairs from cancerous. The RNA-Seq data derived from the sample illustrated the differencially expression genes among normal, paracancerous and cancerous bladder tissues of human. 3 samples examined: normal tissue, paracancerous tissue, cancerous tissue.

Expression profiling of CD8+ T-cells in peripheral blood (PB) of AML patients

Project description:1) Transcriptional profiles of highly purified (≥ 98%) PB CD8+ T-cells from newly diagnosed AML patients (pre-treatment) were compared to age-matched healthy controls and transcriptional profiles of PB AML CD8+ T-cells from patients who achieved complete remission (CR) versus non-responders (NR) longitudinally, at pre-treatment and upon recovery following induction chemotherapy (paired samples). 2) Transcriptional profiles of PB AML CD8+ T-cells from patients who achieved complete remission (CR) versus non-responders (NR) longitudinally, at pre-treatment (PRE) and upon recovery following induction chemotherapy (POST) (paired samples).

Lin28A/CENPE promoting the proliferation and chemo-resistance of acute myeloid leukemia

Project description:Peripheral blood samples of 3 refractory/relapsed AML patients (R/R-AML, relapsed/refractory AML patients who failed to achieve complete remission/CR after 2 courses of induction chemotherapy), 3 refractory secondary AML patients (S-AML, MDS or MPN derived AML patients did not reach CR after 2 rounds of induction chemotherapy), 4 de novo AML patients (AML, CR after standard “3+7” induction chemotherapy), and 3 healthy controls (HC) were collected. Nanodrop was applied to quantify the total RNA samples. Illumina kits were used to prepare the RNA-seq library.

Implications of the miR-10 family in chemotherapy response of NPM1 mutated AML

Project description:Nucleophosmin mutated AML (NPM1mut-AML) patients have a high rate of complete remission (CR) to induction chemotherapy. However, the mechanisms responsible for such effects are unknown. Since miR-10 family members are expressed at high levels in NPM1mut-AML, we evaluated whether these microRNAs could predict chemotherapy response in AML. We found that high baseline miR-10 family expression in 54 untreated cytogenetically heterogeneous AML patients was associated with achieving CR. However, when we included NPM1 mutation status in the multivariable model, there was a significant interaction effect between miR-10a-5p expression and NPM1 mutation status. Similar results were observed when using a second cohort of 183 cytogenetically normal older (ageM-bM-^IM-%60 years) AML patients. Loss and gain of function experiments using miR-10a-5p in cell lines and primary blasts did not demonstrate any effect in apoptosis or cell proliferation at baseline or after chemotherapy. These data support a bystander role for the miR-10 family in NPM1mut-AML. Pretreatment miRNA expression was analyzed in 54 de novo adult AML patients obtained from the MD Anderson Cancer Center Leukemia Tissue Bank (LTB) using the Ohio State University (OSU) miRNA microarray (ver.3).

Transcriptome of primary acute myeloid leukemia (AML) cells treated with AICAr

Project description:Ribonucleoside AICAr, a precursor in purine synthesis and a known activator of AMPK, was shown to induce monocytic differentiation in AML cell lines by inducing pyrimidine depletion followed by activation of ATR/Chk1 pathway and cell cycle arrest. Here we report transcriptional changes induced by AICAr in the primary AML sample (FAB-M2, FLT3 negative, NPM1 negative) in which AICAr induced differentiation and accumulation of macrophage cells in vitro. RNA-seq transcriptome analysis of primary AML cells isolated from the bone marrow of a patient with de novo FAB-M2 AML. Mononuclear cells were isolated from the bone marrow sample by density gradient separation and grown in RPMI supplemented with 10% FBS, 2 mM L-glutamine, 50 U/ml penicillin, 50 μg/ml streptomycin and 50 ng/ml IL-3, IL-6, SCF and FLT3L. Cells were treated with AICAr (0.4 mM) for 24 h. Experiment was performed in biological triplicates and total RNA was isolated for transcriptome analysis using Illumina high throughput sequencing.
