ITR‑284 is a carboxamide analog that can inhibit proliferation in human promyelocytic leukemia HL-60 cells. To understand the effects and molecular mechanisms of ITR‑284 in human erythromyeloblastoid leukemia, we treated K562 cells with different concentrations of ITR‑284 (0, 2, 4, 6, 8 and 10 nM) and all-trans retinoic acid (ATRA) (0, 0.1, 0.5, 1, 5 and 10 µM) for 24 h. The IC50 of ITR‑284 was ~10 nM in K562 cells treated for 24 h as determined by MTT assay. May-Grünwald-Giemsa staining and nitro blue tetrazolium (NBT) assays were used to determine cell morphology changes and differentiation after ITR‑284 and ATRA treatment...

Forkhead box (FOX) genes encode transcription factors, which regulate embryogenesis and play an important role in hematopoietic differentiation and in mesenchymal niche maintenance. Overexpression of the family member FOXC1 has been reported in solid tumors and acute myeloid leukemia (AML). We studied FOXC1 expression and function in acute promyelocytic leukemia (APL) and normal hematopoietic progenitors. FOXC1 mRNA and protein levels were significantly lower in primary marrow samples from 27 APL patients, as compared to samples obtained from 27 patients with other AML subtypes, and 5 normal CD34+ hematopoietic cells...

We assessed the association between 1,414 single nucleotide polymorphisms (SNPs) in genes involved in synthesis and metabolism of steroid hormones and IGF-1, and risk of breast cancer in situ (BCIS), with the aim of determining whether any of these were disease specific. This was done using 1,062 BCIS cases and 10,126 controls as well as 6,113 invasive breast cancer cases from the Breast and Prostate Cancer Cohort Consortium (BPC3). Three SNPs showed at least one nominally significant association in homozygous minor versus homozygous major models...

Acute promyelocytic leukemia (APL) is characterized by a specific chromosomal translation, resulting in a fusion gene that affects the differentiation, proliferation and apoptosis of APL cells. Epigallocatechin-3-gallate (EGCG), a catechin, exhibits numerous biological functions, including antitumor activities. Previous studies have reported that EGCG induces apoptosis in NB4 cells. However, the molecular mechanism underlying EGCG-induced apoptosis remains unclear. The present study aimed to determine the molecular basis of EGCG-induced apoptosis in NB4 cells...

Xanthones are phytochemical compounds found in a number of fruits and vegetables. Characteristically, they are noted to be made of diverse properties based on their biological, biochemical, and pharmacological actions. Accordingly, the apoptosis mechanisms induced by beta-mangostin, a xanthone compound isolated from Cratoxylum arborescens in the human promyelocytic leukemia cell line (HL60) in vitro, were examined in this study. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay was done to estimate the cytotoxicity effect of β-mangostin on the HL60 cell line...

Respiratory syncytial virus (RSV) is the most important cause of viral acute respiratory tract infections and hospitalizations in children, for which no vaccine or specific treatments are available. RSV causes airway mucosa inflammation and cellular oxidative damage by triggering production of reactive oxygen species and by inhibiting at the same time expression of antioxidant enzymes, via degradation of the transcription factor NF-E2-related factor 2 (NRF2). RSV infection induces NRF2 deacetylation, ubiquitination, and degradation through a proteasome-dependent pathway...

To examine the in vivo responses of promyelocytic leukemia protein (PML) to arsenic, rats (male, 6 weeks old, Sprague Dawley) were administered a single intraperitoneal dose of 5 mg/kg arsenic trioxide (ATO). The protein was examined in the heart, lung, liver, and brain 6 and 48 hours after administration: a significant response of PML was observed in the brain. Oxidative DNA modification was also observed in the brain as revealed by increased immunoreactivity to anti-8-hydroxy-2'-deoxyguanosine (8-OHdG) antibody...

All-trans retinoic acid (ATRA) resistance has been a critical problem in acute promyelocytic leukemia (APL) relapsed patients. In this study, dasatinib synergized with ATRA to trigger differentiation in ATRA-resistant APL cell lines. The combined treatment activated RAF-1, MEK and ERK as well as enhanced ATRA-promoted up-regulation of the protein level of PU.1, C/EBPβ and C/EBPε. U0126 (MEK specific inhibitor) and sorafenib tosylate (RAF-1 specific inhibitor) suppressed the combined treatment-induced differentiation, ERK phosphorylation and the up-regulation of C/EBPs and PU...

Gammaherpesviruses like Epstein-Barr virus (EBV) and Kaposi's sarcoma-associated herpesvirus (KSHV) subvert the ubiquitin proteasome system for their own benefit in order to facilitate viral gene expression and replication. In particular, viral tegument proteins that share sequence homology to the formylglycineamide ribonucleotide amidotransferase (FGARAT, or PFAS), an enzyme in the cellular purine biosynthesis, are important for disrupting the intrinsic antiviral response associated with Promyelocytic Leukemia (PML) protein-associated nuclear bodies (PML-NBs) by proteasome-dependent and independent mechanisms...

Recombinant human soluble thrombomodulin (rTM) is a newly developed anti-coagulant approved for treatment of disseminated intravascular coagulation (DIC) in Japan. rTM exerts anti-inflammatory and cytoprotective functions via its lectin-like and epidermal growth factor-like domains, respectively. In this study, we retrospectively reviewed the treatment of 21 consecutive patients with coagulopathy, complicated by acute promyelocytic leukemia (APL), with all-trans retinoic acid (ATRA) with or without combination with rTM...

Promyelocytic leukemia nuclear bodies (PMLNB) are sub-nuclear organelles which are the hub of numerous proteins. DNA/RNA viruses often hijack cellular-factors resident in PML-NBs to promote their proliferation in host cells. Hepatitis B virus (HBV), belonging to Hepadnaviridae family, remains undetected in early infection as it does not induce the innate immune response and is known to be the cause of several hepatic diseases leading to cirrhosis and hepatocellular carcinoma. The association of PML-NB proteins and HBV is being addressed in a number of recent studies...

Acute myeloid leukemia (AML) is a malignancy of myeloid progenitor cells that are blocked in differentiation. Acute promyelocytic leukemia (APL) is a rare form of AML, which generally presents with a t(15;17) translocation causing expression of the fusion protein PML-RARA. Pharmacological doses of all-trans retinoic acid (ATRA) induce granulocytic differentiation of APL cells leading to cure rates of >80% if combined with conventional chemotherapy. Autophagy is a lysosomal degradation pathway for the removal of cytoplasmic content and recycling of macromolecules...

The treatment of acute leukemia is still challenging due in part to the development of resistance and relapse. This chemotherapeutics resistance is established by clonal selection of resistant variants of the cancer cells. Recently, a horizontal transfer of chemo-resistance among cancer cells via extracellular vesicles (EVs) has been suggested. The aim of this research was to investigate the role of EVs in chemo-resistance in acute myeloid leukemia. For this purpose, the sensitive strain of the promyelocytic leukemia HL60 cell line was studied along with its multi-resistant strain, HL60/AR that overexpresses the multidrug resistance protein 1 (MRP-1)...

The mouse Shb gene coding for the Src Homology 2-domain containing adapter protein B has recently been placed in context of BCRABL1-induced myeloid leukemia in mice and the current study was performed in order to relate SHB to human acute myeloid leukemia (AML). Publicly available AML databases were mined for SHB gene expression and patient survival. SHB gene expression was determined in the Uppsala cohort of AML patients by qPCR. Cell proliferation was determined after SHB gene knockdown in leukemic cell lines...

We have previously demonstrated that the death-associated protein kinase 2 (DAPK2) expression is significantly reduced in acute myeloid leukemia (AML), particularly in acute promyelocytic leukemia (APL) blast cells. In this study, we aimed at further understanding DAPK2 function and regulation during arsenic trioxide (ATO) cytotoxic or all-trans retinoic acid (ATRA) differentiation therapy in APL cells. We found that the p53 family member transactivation domain-p73 isoform (TAp73) binds to and activates the DAPK2 promoter, whereas the dominant-negative ΔNp73 isoform inhibits DAPK2 transcription...

BACKGROUND: Arsenic trioxide (ATO) is highly effective in the treatment of patients with acute promyelocytic leukemia (APL). It is a chemotherapeutic agent that has been shown to induce apoptosis in several tumor cell lines. However, research into its effects on colon carcinoma cells is still very limited. We previously reported that ATO is cytotoxic and causes DNA damage in HT-29 human colorectal adenocarcinoma cells. In the present study, we further evaluated its effect on oxidative stress (OS), and examined its apoptotic mechanisms of action on HT-29 cells...

Promyelocytic leukemia (PML) nuclear bodies (NBs) recruit partner proteins, including p53 and its regulators, thereby controlling their abundance or function. Investigating arsenic sensitivity of acute promyelocytic leukemia, we proposed that PML oxidation promotes NB biogenesis. However, physiological links between PML and oxidative stress response in vivo remain unexplored. Here, we identify PML as a reactive oxygen species (ROS) sensor. Pml(-/-) cells accumulate ROS, whereas PML expression decreases ROS levels...

Oxidative stress and inflammation play a role in the physiopathology of insulin resistance, diabetes and cardiovascular disease. A single high-fat, high-carbohydrate (HFHC) meal induces an increase in inflammatory and oxidative stress markers in peripheral blood mononuclear cells (PBMC). Previous studies have shown that orange juice is able to prevent this response by inhibiting toll like receptors (TLR) expression and endotoxemia. Our goal was to study the proteome response in PBMC after the consumption of a HFHC meal consumed with water, orange juice or an isocaloric beverage (water with glucose)...

Arsenic trioxide (ATO) is used as a chemotherapeutic agent for the treatment of acute promyelocytic leukemia. However, increasing drug resistance is reducing its efficacy. Therefore, a better understanding of ATO resistance mechanism is required. In this study, we established an ATO-resistant human epidermoid carcinoma cell line, KB/ATO, from its parental KB-3-1 cells. In addition to ATO, KB/ATO cells also exhibited cross-resistance to other anticancer drugs such as cisplatin, antimony potassium tartrate, and 6-mercaptopurine...
