Project description:The branched-chain amino acid (BCAA) metabolism plays pleiotropic roles in homeostasis. Here we show that human acute leukemia-initiating cells (LICs), but not normal hematopoietic stem cells, are heavily addicted to the BCAA metabolism, irrespective of myeloid or lymphoid types. To clarify how BCAA metabolism affect the gene expression of human acute leukemia cells, we examined the gene expression alteration in human acute leukemia cell lines in control and BCAA-resrticted culture conditions.

Project description:To clarify the global gene expression alteration in primary CD34+ AML cells after BCAA metabolism inhibition, CD34+ AML cells were treated with or without gabapentin in vitro. After 9-12 hours of culture with or without gabapentin, FACS-purified CD34+ AML cells were subjected to transcriptome analysis.

Project description:We used RNA-Seq to ask whether the transcripts for the proposed BCKDH subunits are upregulated in wild-type plants subjected to prolonged darkness. These experiments were performed using rosette leaves from 5-week-old, short-day-grown (8h light/16h dark) Col-0 wild-type plants moved to constant darkness for 6h, 24h, 48h and 72h, and grown in short day for 72h as control. The transcripts of eight BCAA catabolism genes were increased nine- to 400-fold within the first 6h of prolonged darkness, and remained high until the last time point. These results are consistent with the hypothesis that BCAA catabolic enzymes - including BCKDH subunits E1A1, E1B1, E1B2 and E2 - have one or more physiological roles in the dark. Rosette leaf mRNA profiles of 5-week old Col wild type (WT, CS60000) and BCAA catabolic mutants ivd1-2 and hml1-2 were generated byRNA sequencing, in duplicate, using Illumina HiSeq2500.
Project description:Comparative transcriptome profiles of patient-derived Sezary cells and cultured Sezary cell line (Hut78) mycosis fungoides cell line (Hut 102) and non-Sezary T cell leukemia cell line (Jurkat) relative to benign CD4+ T cells from individuals with no T cell malignancy. There are three goals. The first and primary goal is to establish a list of genes with differential expression between Sezary cells and the benign CD4+ T cell counter part from individuals without Sezary syndrome. A secondary goal is to examine if these differentially expresses genes in clinical samples of Sezary cells are preserved in Hut78 and Hut102 cells, which are the two most frequently used experimental cell models of Sezary cells in the research community. The third goal is to examine if these Sezary cell specific genes are also present in a non-Sezary T cell malignancy, such as Jurkat cells, which is derived from a non-Sezary cell T cell leukemia patient.

Two color experiment, 6 biological replicates (6 unique patients) with Sezary syndrome, 1 Hut78 cell,1 Hut102 cell and 1 Jurkat cell lines as the experimental samples, each compared with a distinct individual with no T cell malignancy of the skin or the blood.
