Proteome dynamics of HL-60, NB4, and K562 cells under the ATRA treatment

Project description:Searching for new strategies of acute myeloid leukemia (AML) treatment is of particular interest. Cell lines, e. g. HL-60 and NB4, represent model systems to study molecular features of leukemic cells. The all-trans-retinoic acid (ATRA) has proven itself to be an effective treatment for one of AML subtypes, i.e., acute promyelocytic leukemia (APL). At the same time, ATRA causes granulocytic differentiation of non-APL leukemic cells in vitro. Combination of new therapeutics with ATRA could improve efficiency of treatment. Studying the proteome perturbation in leukemic cells under the ATRA treatment allows to determine potential regulatory molecules that could be affected pharmacologically. Thus, the TMT-based proteomic profiles of HL-60, NB4, and K562 cell lines under the ATRA treatment were obtained at 0, 3, 12, 24, and 72 h after the ATRA treatment.

Gene expression profiling of ATRA-resistant NB4-MR4 subclone (R4 cell line) treated with a CHK1 inhibitor i(MK-8776).

Project description:Acute promyelocytic leukemia (APL) is a hematological disease characterized by a balanced reciprocal translocation that leads to the synthesis of the oncogenic fusion protein PML-RARα. APL is mainly managed by a differentiation therapy based on the administration of all-trans retinoic acid (ATRA) and arsenic trioxide (ATO). However, therapy resistance, differentiation syndrome, and relapses require the development of new low-toxicity therapies based on the induction of blasts differentiation. Here, we performed a high-throughput gene expression profile of the ATRA-resistant acute promyelocytic leukemia (APL) cellline (aka R4) treated with a CHK1 inhibitor or DMSO as control.

Expression profiling of myeloid leukemia cell treated with vibsanin A, PMA and ATRA

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 vibsanin A promotes the differentiation of myeloid leukemia cell lines and primary AML blasts. To reveal how vibsanin A function on promoting myeloid leukemia cell differentiation, we analyzed and compared the gene expression profiles in myeloid leukemia HL-60 cells treated with vibsanin A, PMA, and ATRA.

NB4 cell line untreated and induced to differentiate by a 48h exposure to 1µM ATRA

Project description:NB4 is a cell line model of acute promyelocytic leukemia (APL).The t(15;17) translocation and consequent expression of the PML (Promyelocytic Leukemia Protein)/RARalpha (Retinoic Acid Receptor Alpha) fusion protein blocks differentiation at the promyelocytic stage.The PML portion of the PML/RARalpha fusion protein has a high affinity for the corepression complex, preventing RARalpha transcriptional activity. To induce complete remission in a high proportion of patients, a pharmacological dose of ATRA is required to destabilize this interaction and re-establish the differentiation program.

All-trans retinoic reduces the levels of cardiolipins in the NB4 acute promyelocytic leukemia cell-line affecting the autophagy and differentiation responses

Project description:All-trans retinoic (ATRA) is used in the treatment of acute promyelocytic leukemia a rare form of AML characterized by the presence of a specific translocation involving chrosomes 15;17 and causing the production of the PML-RARα fusion protein in 95% of the cases. ATRA differentiates the APL blasts into neutrophilic granulocytes which are short lived cells. This effect is at the basis of the therapeutic effect of ATRA.

Transcription profiling by array of ATRA- and control-treated NB4 leukemia cells

Project description:The acute promyelocytic leukemia-derived cell line, NB4, was grown at 37°C in 5% CO2 in an RPMI medium supplemented with 2 mM L-glutamine and 10% decomplemented fetal calf serum. Cells were cultured for 48 h with or without 1 μM All-trans retinoic acid (ATRA). Duplicates of 3 independent experiments were analyzed.

OCI/AML2 ATRA AND VPA GENE EXPRESSION

Project description:Purpose: Treatment of acute promyelocytic leukemia (APL) with the retinoid, all trans retinoic acid (ATRA), along with standard chemotherapy has significantly improved survival compared to chemotherapy alone1. ATRA mediates its benefit in APL by overcoming the transcriptional block mediated by PML-RAR-alpha fusion oncoprotein, thereby, restoring expression of retinoid response genes2. The therapeutic benefits observed with ATRA treatment in APL have not been achieved in the other more common sub-types of acute myeloblastic leukemia (AML)3. This likely reflects the recruitment of histone deacetylase complexes by other recurrent chromosomal translocations in AML cells4. In this experiment, we evaluated if treatment of the AML cell line, OCI/AML-2, with the histone deacetylase inhibitor, valproic acid (VPA), would alter the expression of sub-sets of genes by itself or in conjunction with ATRA that have been shown to be modulated by ATRA in APL2.
