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

ABSTRACT: 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.

CAMKK and CRAC channel regulate autophagy, differentiation and apoptosis in acute promylocytic leukemia cells treated by ATRA

Project description:ATRA is an active metabolite of vitamin A that is frequently used for the treatment of acute promyelocytic leukemia (APL) patients. Despite the success of this treatment, some APL patients are refractory or relapse. This emphasis the need for new therapeutic strategies aiming to improve the anti-cancer effect of ATRA. We and other have previously shown that autophagy is activated during ATRA-induced granulocytic differentiation of acute promyelocytic leukemia cells. Although the transcription effect of ATRA on autophagy has been well-documented, little is known on the post-transcription/ post-translational regulation autophagy in response to ATRA. Given the importance of calcium ions in the control of autophagy, we hypothesized that calcium ions are involved in the initiation of autophagy by ATRA in APL cells. We thus examined how ATRA regulate intracellular calcium and sense perturbation of Ca2+ responses to autophagy, differentiation and cell death in APL cells.

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.

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.

Co-targeting leukemia-initiating cells and leukemia bulk leads to disease eradication

Project description:Co-targeting the plasticity and heterogeneity of cancer is fundamental to achieve and maintain complete remission (CR). We exploited murine models of acute promyelocytic leukemia (APL), a subtype of acute myeloid leukemia driven by the promyelocytic leukemia/retinoic acid receptor (PML-RARα) oncofusion protein, which recruits histone deacetylase (HDAC)-containing complexes. We investigated the effect of two HDAC inhibitors: valproic acid (VPA), and SAHA/vorinostat with all-trans retinoic acid (ATRA), on the bulk cells and LICs of two APLs with different LIC frequencies. VPA and SAHA selectively target the bulk APL cells and LICs respectively. VPA+SAHA+ATRA combination induced CR in an APL model with lower LIC frequency.

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.

Acute myeloid leukemia cell line RNA-Seq

Project description:We performed RNA-Seq on acute promyelocytic leukemia (APL) cells treated with both all-trans retinoic acid (ATRA) and trichostatin A (TSA) to identify transcriptional changes potentially associated with changes in APL cell mechanical properties. As a control, we performed the same treatments and RNA-Seq analysis on HL-60 cells, which were derived from a patient diagnosed with APL but whose cells lacked the hallmark fusion gene associated with APL. We performed RNA-Seq on these three cell lines (AP-1060, NB4, HL-60) under different conditions (untreated, TSA, ATRA, TSA + ATRA), and identified differentially expressed genes between samples and conditions. This study identified differentially expressed genes and enriched gene sets associated with (1) a resistance to differentiation induced by ATRA or (2) changes in mechanical properties. Overall, we find evidence that ATRA resistance and mechanical properties may be linked by the degree of chromatin condensation in APL cells.

Inhibition of the LSD1 (KDM1A) demethylase reactivates the all-trans-retinoic acid differentiation pathway in acute myeloid leukemia [Illumina HumanHT-12 gene expression array]

Project description:All-trans-retinoic acid (ATRA) has been successfully used in therapy of acute promyelocytic leukemia (APL), a cytogenetically distinct subtype of acute myeloid leukemia (AML) but the response of non-APL AML cases to ATRA-based treatment has been poor. Here we show that, via epigenetic reprogramming, inhibitors of LSD1/KDM1 demethylase including tranylcypromine (TCP) unlocked the ATRA-driven therapeutic response in non-APL AML. LSD1 inhibition did not lead to an increase in genome-wide H3 lysine4 dimethylation (H3K4me2) but did increase H3K4me2 and expression of myeloid differentiation-associated genes. Importantly, treatment with ATRA plus TCP dramatically diminished engraftment of primary human AML cells in vivo in NOD.SCID mice, suggesting that ATRA in combination with TCP may target leukemia-initiating cells. Furthermore, initiation of ATRA plus TCP co-treatment 15 days post-engraftment of human AML cells in NOD.SCID gamma mice also revealed the ATRA plus TCP drug combination to have a potent anti-leukemic effect, which was superior to treatment with either drug alone. These data identify LSD1 as a therapeutic target and strongly suggest that it may contribute to AML pathogenesis by inhibiting the normal pro-differentiative function of ATRA, paving the way for novel combinatorial therapies of AML. Overall, 30 specimens derived from HL-60 or TEX cell line were treated with drugs and hybridized to Illumina HumanHT-12 gene expression arrays.
