Project description:Transcriptome analysis was performed to determine what gene expression changes occur in response to treatment of the plant-derived compound harmine and to determine its effect on protein kinase C agonist reactivation of latent HIV.
Project description:K562 cells were treated with 20nM PMA. Cells were harvested after 48 hours and RNA was extracted with miRvana RNA isolation kit. Expression profiling was done on Agilent platform.
Project description:Myeloid leukemia cell lines HL60, THP-1, and U937 undergo macrophage-like differentiation after treatment with phorbol ester. To explore genes whose exon usage was altered during macrophage differentiation, we compared exome of PMA-treated (differentated) and vehicle-treated (undifferentiated) myeloid cell lines.
Project description:The aim of the dataset was to study on a genome-wide level the impact of Lat deficiency on gene expression in resting and activated CD4+ T cells Lat+ and Lat? CD4+ T cells were isolated from lymph nodes and spleen of Latfl-dtr Tmat-Cre mice using a Dynabeads untouched mouse CD4 cells kit (Life Technology) and further purified by cell sorting. Lat+ CD4+ T cells were defined as: CD5+, hDTR+, CD8?, TCR???, CD25?, CD69?, CD62L+, lineage (CD11c, CD11b, CD19, CD45R, CD161)? and Lat? CD4+ Tcells were defined as: CD5+, hDTR?, CD8?, TCR???, CD25?, CD69?, CD62L+, lineage (CD11c, CD11b, CD19, CD45R, CD161)?. Sorted Lat+ or Lat? CD4+ T cells were then kept in vitro for 4 hours without stimulation or activated for 4 hours using anti-CD3 antibody and anti-CD28 antibody. Cell samples corresponding to three biological replicates were analyzed and gene expression profiles were obtained from total RNA.
Project description:FVB/N mice were subjected to 7,12-Dimethylbenz[a]anthracene (DMBA) two-hit multistage skin carcinogenesis protocol. Mice were topically treated with 200 nmol of DMBA in 0.2 mL acetone then twice weekly for six weeks with 5 nmol PMA (Phorbol 12-myristate 13-acetate). A second hit of DMBA was performed on the eighth week followed by the resumption of PMA treatment for 14 more weeks. Control mice were only topically treated with 0.2 mL acetone vehicle. Healthy skins (acetone-treated), hyperplastic skins, papillomas and tumors were harvested throughout the protocol and biopsies were frozen for RNA extraction.
Project description:All-trans retinoic acid (ATRA)-based differentiation therapy has achieved success with the treatment of acute promyelocytic leukemia (APL), a unique subtype of acute myeloid leukemia (AML). However, other subtypes of AML display resistance to ATRA-based treatment. Here, we demonstrate that a novel natural vibsane-type diterpenoid vibsanine A promotes the differentiation of myeloid leukemia cell lines and primary AML blasts. To reveal how vibsanine A function on promoting myeloid leukemia cell differentiation, we analyzed and compared the gene expression profiles in myeloid leukemia HL-60 cells treated with vibsanine A, PMA, and ATRA. HL-60 cells were treated with vibsanine A, PMA and ATRA for 6 hours or longer up to 24 hours. Gene expression profiling was conducted
Project description:ZXDC1 augments the expression of various markers of monocyte/macrophage differentiation when over-expressed in the U937 cell line treated with the phorbol ester PMA. Likewise, knockdown of ZXDC1 restricts the induced expression of these markers. We sought to identify specfic gene targets of ZXDC1 during the process of monocyte/macrophage differentiation in U937 by performing gene expression profiling in cells exhibiting reduced expression of ZXDC1 compared to controls. We used microarray to identify genes regulated by ZXDC during PMA-induced differentiation of U937 monoblasts towards a monocyte/macrophage phenotype
